Frequent neurocognitive deficits after recovery from mild COVID-19.
Neuropsychiatric complications associated with coronavirus disease 2019 caused by the Coronavirus SARS-CoV-2 (COVID-19) are increasingly appreciated. While most studies have focussed on severely affected individuals during acute infection, it remains unclear whether mild COVID-19 results in neurocognitive deficits in young patients. Here, we established a screening approach to detect cognitive deficiencies in post-COVID-19 patients. In this cross-sectional study, we recruited 18 mostly young patients 20–105 days (median, 85 days) after recovery from mild to moderate disease who visited our outpatient clinic for post-COVID-19 care.

The landscape of cognitive function in recovered COVID-19 patients
This study aims to evaluate the impacts of COVID-19 on cognitive functions in recovered patients and its relationship with inflammatory profiles. Twenty-nine patients recovered from COVID-19 as confirmed by negative nucleic tests for two consecutive times were recruited. A total of 29 age-, gender- and education-matched healthy controls were also recruited. The cognitive functions of all subjects were evaluated by the iPad-based online neuropsychological tests, including the Trail Making Test (TMT), Sign Coding Test (SCT), Continuous Performance Test (CPT), and Digital Span Test (DST). Blood samples from all patients were collected for examining inflammatory profiles, including interleukin-2 (IL-2), IL-4, IL-6, IL-10, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and C-reactive protein (CRP). The relationship between cognitive functions and inflammatory profiles were analyzed by Pearson correlation. In results, although no significant differences were found in TMT, SCT, and DST between the two groups, patients with COVID-19 scored lower in the correct number of the second and third parts of CPT, they also scored higher in the missing number of the third part of CPT (all P < 0.05). In patients with COVID-19, there was a trend of significant difference for lower reaction time in the first and second parts of CPT (P = 0.050, and 0.051, respectively), as well as the lower correct number of the second part of CPT (P = 0.050). Correlation analysis showed that the reaction time for the first and second parts of CPT was positively correlated with the CRP levels (r = 0.557 and 0.410, P < 0.05). In conclusion, our findings indicated that cognitive impairments exist even in patients recovered from COVID-19, and might be possibly linked to the underlying inflammatory processes.

Brain Damage And Hallucinations Associated With Even Mild Covid-19 Coronavirus Infection
A new study has warned that potentially deadly brain disorders may be a symptom of Covid-19, even in people with otherwise mild disease.
The research published today in the journal Brain, looked at 40 adult patients with Covid-19 in the U.K., finding that they showed symptoms of a wide range of serious brain diseases. Many of the patients had only mild typical Covid-19 symptoms such as fever or respiratory issues and for some, their neurological symptoms were the only sign they were sick.
One 55-year old woman with no known current or historical mental illness was admitted to hospital with recognized Covid-19 symptoms including fever, cough and muscle aches. She was discharged after two weeks, having been treated with oxygen, but four days later her husband reported she was confused and behaving strangely. She then experienced hallucinations, reporting seeing lions and monkeys in her house, and became delusional and aggressive with her family and hospital staff. She was treated with anti-psychotic medication and her symptoms improved over the course of three weeks, although the study does not confirm whether she made a full recovery.
Other neurological issues experienced by the Covid-19 patients, who ranged in age from 16-85, included more cases of delirium or psychosis, strokes and problems with peripheral nerves found in extremities like hands and feet.

Kids' COVID cases on the rise, but most are mild, new data show
While the proportion of COVID-19 cases in children has tripled or quadrupled since the start of the pandemic, it remains below their proportion of the US population, and hospitalizations and deaths are uncommon—although racial minorities and those with public insurance and underlying conditions appear to be at higher risk for serious outcomes, according to two new studies.
Case growth rate by region, month
In the first study, published late last week in Pediatrics, researchers from the American Academy of Pediatrics and the Children's Hospital Association analyzed COVID-19 case data from the websites of 49 state health departments that report cases by age, as well as from two cities and two territories, starting Apr 16.

Merkel says British coronavirus variant more dangerous to children
BERLIN (Reuters) - A variant of the coronavirus first detected in Britain, and now spreading in Germany, is more dangerous to young people, Chancellor Angela Merkel said on Wednesday.
“The British mutant, and this is the difference with the spring, is proven to be more dangerous in children and young people so we need to put the protection of schools more front and centre than with the original virus,” she told lawmakers.

The most terrifying thing': Some Covid-19 patients are suffering severe psychosis
'There's something happening'
As Belluck explains, while the virus that causes Covid-19 was initially considered primarily a respiratory disease, more and more patients are reporting a host of other symptoms, including neurological, cognitive, and psychological effects. And among these cases is a small but growing number of patients who are experiencing severe "post-Covid psychosis," providers say.
For example, a patient named Ivan Agerton—a 49-year-old documentary photographer living in Seattle, who had no personal or family history of mental illness—began experiencing crippling paranoia and auditory hallucinations weeks after recovering from a mild case of Covid-19. He believed that his neighbors were spying on his family and that police were tracking his movements.
"Like a light switch—it happened this fast—this intense paranoia hit me," Agerton said. "It was really single-handedly the most terrifying thing I've ever experienced in my life."
In another case, Hisam Goueli, a psychiatrist, helped treat a physical therapist in her early 40s who sought help at South Oaks Hospital in New York after she started to hear a voice telling her to kill herself and harm her children. The woman, who had never experienced psychiatric symptoms before, said the symptoms started just months after recovering from a mild case of Covid-19.
Goueli said he was initially unsure whether her case was Covid-related. "But then," he said, "we saw a second case, a third case and a fourth case, and we're like, 'There's something happening.'"
Indeed, while the overall number of these cases remains low—and experts expect the cases to remain rare—the reports aren't merely anecdotal, Belluck reports. A British study of neurological and psychiatric symptoms among 153 Covid-19 patients found that 10 study participants presented with "new-onset psychosis." Similarly, another study identified 10 such patients at a hospital in Spain.
Much about the condition remains a mystery, experts say
While experts don't think this trend is unique to Covid-19—psychotic episodes have sporadically occurred amid other viruses, including the 1918 flu and the SARS and MERS coronaviruses—they note that much about post-Covid psychosis remains a mystery, Belluck writes.
Cheat sheet: Tele-behavioral health
Currently, experts hypothesize that this condition may be associated with how the immune system responds to the virus, including vascular issues or inflammation. "Some of the neurotoxins that are reactions to immune activation can go to the brain, through the blood-brain barrier, and can induce this damage," said Vilma Gabbay, a co-director of the Psychiatry Research Institute at Montefiore Einstein, who has treated two patients with post-Covid psychosis.
As Robert Yolken, a neurovirology expert at Johns Hopkins University School of Medicine, explained, the immune systems of some patients who've physically recovered from Covid-19 remain activated because of "delayed clearance of a small amount of virus."
And that continuing activation of the immune system, according to Emily Severance, an expert in schizophrenia at Johns Hopkins, is currently the leading hypothesis into other brain-related symptoms of Covid-19, such as brain fog and memory loss. It's reasonable to think that post-Covid psychosis may stem from "something similar happening in the brain," she said.
In fact, the variety of symptoms may depend on what part of the brain is affected by the ongoing immune response, Yolken said. He noted that "some people have neurological symptoms, some people psychiatric and many people have a combination."
A different expression of psychosis—and an ambiguous recovery
According to experts, the experience of psychosis among Covid-19 patients seems to differ significantly from how psychosis typically presents.
Webinar series: 'Stay Up to Date' on the latest with Covid-19
For instance, while paranoid delusions typically accompany schizophrenia during late adolescence or dementia in elder adults, post-Covid-19 psychosis so far seems to primarily affect patients in their 30s, 40s, and 50s. "It's very rare for you to develop this type of psychosis in this age range," Goueli said.
In addition, while most people experiencing psychosis generally "don't have insight into their symptoms," several patients with post-Covid psychosis were aware that something was off, according to Veronika Zantop, a psychiatrist who helped treat Agerton.
There's also little consistency in symptoms among those affected by post-Covid-19 psychosis, Belluck writes, although several patients reported experiencing only mild Covid-19. For example, some patients experiencing post-Covid-19 psychosis feel urges to hurt themselves or others, much like Goueli's patient, while others—such as Agerton—experience deep paranoia rather than any violent impulses.
Moreover, while some patients require weeks of hospitalization to identify the right medications, others improve relatively quickly. Goueli's patient, for instance, was hospitalized for four weeks before doctors found a regimen of medicine that alleviated her symptoms and enabled her to return home. She's currently "95% perfect," Goueli said.
And while some patients seem to experience just a one-off episode, others struggle with relapses. For his part, Agerton was hospitalized in a psychiatric ward twice for his psychosis. While he's now returned home and says he's improving, he's still not 100%. "There's this fear of how long is this going to happen," he said. "How long am I going to live with this?"
Ultimately, however, experts hope that studying these individual cases and larger pieces of research can shed light on what remains a challenging and difficult situation. "We don't know what the natural course of this is," Goueli said. "There are just so many unanswered questions" (Belluck, New York Times, 12/28/2020; Belluck, New York Times, 3/22).

The COVID-19 Virus May Have Been in Humans For Years, Study Suggests
The study raises some interesting possibilities regarding the origin of the new coronavirus. One of the scenarios suggests the virus may have been circulating harmlessly in human populations for quite a while before it became the pandemic that's now stopped the world in its tracks.
"It is possible that a progenitor of SARS-CoV-2 jumped into humans, acquiring [new genomic features] through adaptation during undetected human-to-human transmission," the team from the US, UK and Australia writes in the study.
"Once acquired, these adaptations would enable the pandemic to take off and produce a sufficiently large cluster of cases."
The researchers analysed genomic data available from SARS-CoV-2 and other similar coronaviruses, showing that the receptor-binding domain (RBD) sections of SARS-CoV-2 spike proteins were so effective at binding to human cells, they had to be caused by natural selection.
"By comparing the available genome sequence data for known coronavirus strains, we can firmly determine that SARS-CoV-2 originated through natural processes," said one of the researchers, immunologist Kristian Andersen at Scripps Research.
"Two features of the virus, the mutations in the RBD portion of the spike protein and its distinct backbone, rules out laboratory manipulation as a potential origin for SARS-CoV-2."

The chronic neuropsychiatric sequelae of COVID‐19: The need for a prospective study of viral impact on brain functioning..
Physicians treating people hospitalized with COVID-19 report that a large number experience delirium, and that the condition disproportionately affects older adults. An April 2020 study in Strasbourg, France, found that 65% of people who were severely ill with coronavirus had acute confusion — a symptom of delirium1. Data presented last month at the annual meeting of the American College of Chest Physicians by scientists at the Vanderbilt University Medical Center in Nashville, Tennessee, showed that 55% of the 2,000 people they tracked who were treated for COVID-19 in intensive-care units (ICUs) around the world had developed delirium. These numbers are much higher than doctors are used to: usually, about one-third of people who are critically ill develop delirium, according to a 2015 meta-analysis2 (see ‘How common is delirium?’).

COVID-19 cognitive deficits after respiratory assistance in the subacute phase: A COVID-rehabilitation unit experience
Introduction
COVID-19 complications can include neurological, psychiatric, psychological, and psychosocial impairments. Little is known on the consequences of SARS-COV-2 on cognitive functions of patients in the sub-acute phase of the disease. We aimed to investigate the impact of COVID-19 on cognitive functions of patients admitted to the COVID-19 Rehabilitation Unit of the San Raffaele Hospital (Milan, Italy).
Material and methods
87 patients admitted to the COVID-19 Rehabilitation Unit from March 27th to June 20th 2020 were included. Patients underwent Mini Mental State Evaluation (MMSE), Montreal Cognitive Assessment (MoCA), Hamilton Rating Scale for Depression, and Functional Independence Measure (FIM). Data were divided in 4 groups according to the respiratory assistance in the acute phase: Group1 (orotracheal intubation), Group2 (non-invasive ventilation using Biphasic Positive Airway Pressure), Group3 (Venturi Masks), Group4 (no oxygen therapy). Follow-ups were performed at one month after home-discharge.
Results
Out of the 87 patients (62 Male, mean age 67.23 ± 12.89 years), 80% had neuropsychological deficits (MoCA and MMSE) and 40% showed mild-to-moderate depression. Group1 had higher scores than Group3 for visuospatial/executive functions (p = 0.016), naming (p = 0.024), short- and long-term memory (p = 0.010, p = 0.005), abstraction (p = 0.024), and orientation (p = 0.034). Group1 was younger than Groups2 and 3. Cognitive impairments correlated with patients’ age. Only 18 patients presented with anosmia. Their data did not differ from the other patients. FIM (<100) did not differ between groups. Patients partly recovered at one-month follow-up and 43% showed signs of post-traumatic stress disorder.
Conclusion
Patients with severe functional impairments had important cognitive and emotional deficits which might have been influenced by the choice of ventilatory therapy, but mostly appeared to be related to aging, independently of FIM scores. These findings should be integrated for correct neuropsychiatric assistance of COVID-19 patients in the subacute phase of the disease, and show the need for long-term psychological support and treatment of post-COVID-19 patients.

There is one inevitable conclusion from these studies: COVID infection frequently leads to brain damage — particularly in those over 70. While sometimes the brain damage is obvious and leads to major cognitive impairment, more frequently the damage is mild, leading to difficulties with sustained attention.

One-Third of COVID-19 Survivors Develop a Brain Disorder.
Large study finds psychiatric, neurological illnesses common within 6 months after infection
As many as 1 in 3 COVID-19 survivors experience a mental health or neurological disorder within six months of a coronavirus infection, according to a large study published this week in The Lancet Psychiatry. These latest findings add to a growing body of evidence that show COVID-19 can have serious and potentially long-lasting effects on the brain.
Researchers analyzed data from more than 236,000 patients diagnosed with COVID-19 and found that about 34 percent were diagnosed with a neurological or mental health disorder following their bout with the coronavirus. For nearly 13 percent of these patients, it was their first time receiving such a diagnosis.

A study suggests that in the United States in 2020, around a third of COVID-19 survivors were diagnosed with a neurological or mental health condition within 6 months of their COVID-19 diagnoses.
Anxiety and mood disorders were the most common diagnoses.
Neurological conditions, such as stroke and dementia, occurred less often but were more common among people with severe COVID-19.
The overall effect of these disorders, many of which are chronic, may be substantial for health and social care systems due to the scale of the pandemic.

COVID-19’s Effects on the Brain.
Autopsy studies have yet to find clear evidence of destructive viral invasion into patients’ brains, pushing researchers to consider alternative explanations of how SARS-CoV-2 causes neurological symptoms.
When epidemics and pandemics washed over humanity through the ages, watchful doctors noticed that in addition to the usual, mostly respiratory ailments, the illnesses also seemed to trigger neurological symptoms. One British throat specialist observed in the late 1800s that influenza appeared to “run up and down the nervous keyboard stirring up disorder and pain in different parts of the body with what almost seems malicious caprice.” Indeed, some patients during the 1889–92 influenza pandemic reportedly became afflicted with psychoses, paranoia, stabbing pains, and nerve damage. Similarly, scholars have linked the 1918 flu pandemic to parkinsonism, neuropsychiatric disorders, and a broadly coinciding outbreak of the “sleeping sickness” encephalitis lethargica, which would often arrest patients in a coma-like state—although researchers still debate whether the two are causally connected.
That SARS-CoV-2, the culprit of the COVID-19 pandemic, is also associated with neurological symptoms isn’t entirely surprising, given some evidence that its close relatives, MERS-CoV and SARS-CoV-1, have been associated with neurological symptoms too. But the proportion of patients developing such symptoms—and their mounting collective numbers—has startled some scientists. When the news broke early last year that some 36 percent of COVID-19 patients in Wuhan hospitals were developing impaired consciousness, seizures, sensory impairments, and other neurological symptoms, “that floored me,” remarks Shibani Mukerji, a neuroinfectious disease specialist at Massachusetts General Hospital.

How Covid-19 can damage the brain.
For Julie Helms, it started with a handful of patients admitted to her intensive care unit at Strasbourg University Hospital in northeast France in early March 2020. Within days, every single patient in the ICU had Covid-19 – and it was not just their breathing difficulties that alarmed her.
“They were extremely agitated, and many had neurological problems – mainly confusion and delirium,” she says. “We are used to having some patients in the ICU who are agitated and require sedation, but this was completely abnormal. It has been very scary, especially because many of the people we treated were very young – many in their 30s and 40s, even an 18-year-old.”
Helms and her colleagues published a small study in the New England Journal of Medicine documenting the neurological symptoms in their Covid-19 patients, ranging from cognitive difficulties to confusion. All are signs of “encephalopathy” (the general term for damage to the brain) – a trend that researchers in Wuhan had noticed in coronavirus patients there in February.

Taking a Closer Look at COVID-19’s Effects on the Brain
While primarily a respiratory disease, COVID-19 can also lead to neurological problems. The first of these symptoms might be the loss of smell and taste, while some people also may later battle headaches, debilitating fatigue, and trouble thinking clearly, sometimes referred to as “brain fog.” All of these symptoms have researchers wondering how exactly the coronavirus that causes COVID-19, SARS-CoV-2, affects the human brain.
In search of clues, researchers at NIH’s National Institute of Neurological Disorders and Stroke (NINDS) have now conducted the first in-depth examinations of human brain tissue samples from people who died after contracting COVID-19. Their findings, published in the New England Journal of Medicine, suggest that COVID-19’s many neurological symptoms are likely explained by the body’s widespread inflammatory response to infection and associated blood vessel injury—not by infection of the brain tissue itself [1].
The NIH team, led by Avindra Nath, used a high-powered magnetic resonance imaging (MRI) scanner (up to 10 times as sensitive as a typical MRI) to examine postmortem brain tissue from 19 patients. They ranged in age from 5 to 73, and some had preexisting conditions, such as diabetes, obesity, and cardiovascular disease.
The team focused on the brain’s olfactory bulb that controls our ability to smell and the brainstem, which regulates breathing and heart rate. Based on earlier evidence, both areas are thought to be highly susceptible to COVID-19.
Indeed, the MRI images revealed in both regions an unusual number of bright spots, a sign of inflammation. They also showed dark spots, which indicate bleeding. A closer look at the bright spots showed that tiny blood vessels in those areas were thinner than normal and, in some cases, leaked blood proteins into the brain. This leakage appeared to trigger an immune reaction that included T cells from the blood and the brain’s scavenging microglia. The dark spots showed a different pattern, with leaky vessels and clots but no evidence of an immune reaction.

How COVID-19 Affects the Brain
COVID-19 has resulted in more than 120 million cases and 2.6 million deaths to date. Respiratory and gastrointestinal symptoms are accompanied by short- and long-term neuropsychiatric symptoms (NPs) and long-term brain sequelae.
Some patients present with anosmia, cognitive and attention deficits (ie, brain fog), new-onset anxiety, depression, psychosis, seizures, and even suicidal behavior.1,2 These present before, during, and after respiratory symptoms and are unrelated to respiratory insufficiency,1 suggesting independent brain damage. Follow-ups conducted in Germany and the United Kingdom found post–COVID-19 NPs in 20% to 70% of patients, even in young adults, and lasting months after respiratory symptoms resolved,1 suggesting brain involvement persists.
Entering through angiotensin-converting enzyme 2 receptors,2 SARS-CoV-2 can damage endothelial cells leading to inflammation, thrombi, and brain damage. Moreover, systemic inflammation leads to decreased monoamines and trophic factors and activation of microglia, resulting in increased glutamate and N-methyl-d-aspartate (NMDA)3 and excitotoxicity (Figure). These insults induce new-onset or re-exacerbation of preexisting NPs.

Cognition and COVID-19 – What we know
Nearly a year on from the first outbreak of COVID-19, we still have a lot to learn about how the virus works and affects our health. In this article Operational Scientist, Iona Pickett, explores our current understanding of the neuropsychological consequences of COVID-19, in particular the impact on cognitive function.
Nearly a year on from the first outbreak of COVID-19, we still have a lot to learn about how the virus works and affects our health. It is becoming increasingly clear though that many patients recovering from COVID-19 are also experiencing neurological, psychiatric, and cognitive problems (1-4). These symptoms are estimated to be present in up to a third of COVID-19 patients who have been hospitalised(3,4).These symptoms also appear to persist long after recovery from the initial infection, with detrimental effects on patient quality of life(3, 5-7). With a vaccine on the horizon, and hopefully an end to the pandemic, it is time to start assessing the needs of COVID-19 survivors and providing support for their long-term recovery. This article explores our current understanding of the neuropsychological consequences of COVID-19, in particular the impact on cognitive function.

Altered global brain signal in schizophrenia
This study identified elevated global brain signal variability in schizophrenia, but not bipolar illness. This variability was related to schizophrenia symptoms. A commonly used analytic procedure in neuroimaging, global signal regression, attenuated clinical effects and altered inferences. Furthermore, local voxel-wise variance was increased in schizophrenia, independent of global signal regression. Finally, neurobiologically grounded computational modeling suggests a putative mechanism, whereby altered overall connection strength in schizophrenia may underlie observed empirical results.

If the patient is a danger to himself or others and is unwilling to seek treatment, they can be involuntarily committed to a hospital and held for a period of evaluation usually lasting three to seven days. A court order is required for involuntary commitment to be extended.11
Film and news media have characterized schizophrenia as a violent condition, however, the majority of people with schizophrenia are not violent. The majority of violent crime is committed by individuals who do not suffer from this disorder. The risk of violence in schizophrenia drops dramatically when treatment is in place.12

2018: Burden of schizophrenia increasing globally.
Schizophrenia is a complex mental disorder, with typical onset in late adolescence or early adulthood. Despite intensive and ongoing research, outcomes from best-practice treatment are often suboptimal. A systematic review based on 50 outcome studies reported that the median proportion of people with schizophrenia who met clinical and social recovery criteria was only 13.5%.1
In addition to poor recovery outcomes, those living with schizophrenia have a significantly reduced life expectancy.2 High excess mortality is found across all age groups3 and this differential mortality gap between those with and without schizophrenia may have increased in recent decades.4 Schizophrenia has also been linked to higher rates of comorbid illnesses and most excess deaths are due to underlying physical illnesses, especially chronic diseases such as coronary heart disease, stroke, type II diabetes, respiratory diseases, and some cancers.2 Unnatural causes, including suicide, account for less than 15% of excess deaths.3
Findings from the 2016 global burden of disease study indicated that population growth and aging has led to an increasing disease burden attributable to schizophrenia globally, especially in middle-income countries.
“Developing health services for schizophrenia will require robust and informative epidemiological estimates, including estimates of the number of people living with schizophrenia in a given population and how these have changed over time — estimates that are currently unavailable for schizophrenia,” Fiona J. Charlson, MIPH, PhD, of the University of Queensland School of Public Health in Australia, and the Institute for Health Metrics and Evaluation at University of Washington, and colleagues wrote. “Recent innovations in statistical modeling, as part of the global burden of disease studies, have allowed for the derivation of detailed and comparable epidemiological estimates for schizophrenia by age, sex, geography, and year.”
Charlson and colleagues reported the global disease burden study 2016 estimates of schizophrenia prevalence and burden of disease. In this systematic review, the researchers identified studies reporting the prevalence, incidence, remission and/or excess mortality relating to schizophrenia, then entered estimates into the Bayesian meta-regression tool used in the 2016 global disease burden study to obtain prevalence for 20 age groups, seven super-regions, 21 regions and 195 countries/territories. They obtained burden of disease estimates for schizophrenia by multiplying the prevalence specifically for age, sex, year and location.
In total, 129 individual data sources were included in the systematic review. The results showed that the prevalent cases rose from 13.1 (95% uncertainty interval [UI], 11.6–14.8) million in 1990 to 20.9 (95% UI, 18.5–23.4) million cases in 2016 worldwide. According to the global disease burden study, schizophrenia contributes 13.4 (95% UI, 9.9–16.7) million years of life lived with disability to the worldwide burden of disease.
Analysis demonstrated that the estimated global age-standardized point prevalence of schizophrenia in 2016 was 0.28% (95% UI, 0.24–0.31), with no differences between sexes. Furthermore, there were no large differences between age-standardized point prevalence rates across countries or regions globally.
Globally, an estimated 21 million people are living with schizophrenia and this number will continue to rise with population ageing and growth, according to the researchers. The findings showed that most people live in low- and middle-income countries.
“Health systems in low- and middle-income countries need to prepare for this increase, but existing evidence-based interventions have been poorly implemented, with only 31% of people with schizophrenia accessing treatment in low- and middle-income countries, where the overall mental disorders treatment gap is as high as 89%,” Charlson and colleagues wrote in Schizophrenia Bulletin.
Differences in disability adjusted life years per income status showed that the burden of schizophrenia experienced in lower- and upper-middle income countries was roughly four times that experienced by high-income countries, largely due to the growing populations of these lower income countries.
“This calls for an urgent scaling up of services to respond to serious mental disorders such as schizophrenia,” the researchers wrote. “Health systems in most countries are unprepared for this escalating burden and without action to scale-up services, a lack of effective treatment for this debilitating mental disorder will critically impact individuals and their families.” – by Savannah Demko

People With Schizophrenia Have Increased Risk of Dying From COVID-19, Research Reveals..
Mark Olfson, M.D., MPH
Professor, Epidemiology and Psychiatry
Columbia University Medical Center
A newly published study based on data from a 2020 peak period of the pandemic in New York City indicates that people previously diagnosed with schizophrenia or a schizophrenia spectrum disorder who contracted a COVID-19 infection had a significantly increased risk of mortality. Specifically, their risk of death from COVID within 45 days of infection was 2.7 times the risk in people without a psychiatric diagnosis who contracted COVID.
The observed increase in COVID mortality risk for people on the schizophrenia spectrum was second highest in the study, following the elevated risk associated with age. By comparison, people who had previously suffered heart failure had 1.6 times the risk of those without a psychiatric diagnosis, while those with a history of diabetes had 1.27 times the risk.
The mortality risk within 45 days of COVID diagnosis was also elevated in people who had a recent diagnosis of mood disorders, after demographic factors were factored into the calculation. But this excess risk was not present statistically after various medical risk factors were taken into consideration.
There was no observed relation detected between COVID-related mortality and a stable, established mood disorder or with recent or previously established anxiety disorders.
The study, appearing in JAMA Psychiatry, was based on medical records complied in the spring of 2020 at the NYU Langone Medical Center in New York. Donald C. Goff, M.D., of NYU Langone was senior member of the team. He is a 2009 and 2003 BBRF Independent Investigator. The team also included 2005 BBRF Distinguished Investigator Mark Olfson, M.D., MPH, of Columbia University.
Electronic medical records of 26,540 patients tested within the multi-center NYU Langone health system were the basis for the study. Of these, 7,348 tested positive for COVID-19; 53% were women and the average age was about 54.
75 (1%) of those receiving a positive COVID test had a history of schizophrenia; 564 (7.7%) had a history of a mood disorder; and 360 (4.9%) had a history of an anxiety disorder. The sample was demographically diverse and reflected a consecutive stream of adult patients tested in the NYU Langone system between March 3 and May 31, 2020. Outcomes including mortality (death or discharge to a hospice) were monitored for 45 days following each positive COVID diagnosis.
A systematic study led by BBRF Scientific Council member Nora Volkow, M.D., and based on the electronic health records of over 61 million American adults recently found that people with a diagnosis of a mental disorder within the last 12 months have a significantly increased risk for COVID-19 infection and tend to have worse outcomes than people infected with COVID-19 who don’t have a mental disorder.
Results of the new study revealing the elevated risk of death in people with schizophrenia in the 45 days following a COVID infection should be important, the researchers said, in “guiding clinical decision-making, including the need for enhanced monitoring and targeted interventions” in such patients.
The result in schizophrenia may have reflected “unmeasured medical comorbidities,” the researchers said. But they also pointed out that “the risk remained significantly increased after adjustment for multiple established risk factors.”
It has been noted previously that people with severe mental illness are more likely to live in crowded housing, institutional or otherwise, and may either lack or eschew the need for personal protective equipment to avoid COVID inflection. Yet the increased risk of death from COVID seen in people with schizophrenia may also indicate the presence of biological factors related to schizophrenia or to treatments for it that the current study was not designed to detect, the researchers said.
The team speculates that among the biological factors that may make people with schizophrenia more vulnerable to COVID infection are dysregulation of the body’s immune system, deficits in cellular immunity, and irregularities in immune-system signaling. Evidence for all of these has been generated in many previous studies of schizophrenia, including studies of the genes that tend to be perturbed in people who have the illness.
Unable based on their study to forge more precise biological linkages, the researchers stressed the practical clinical need of “targeted interventions for patients with severe mental illness to prevent worsening health disparities” in circumstances such as are being faced now in the continuing COVID pandemic.

Schizophrenia Tied to Higher Risk of COVID-19 Death
— Increased mortality risk not seen with mood and anxiety disorders
People with schizophrenia may face a higher risk for severe COVID-19, a new study suggested.
Compared with COVID-19 patients without a psychiatric disorder, those previously diagnosed with schizophrenia spectrum disorder had more than a two times higher risk for mortality within 45 days of a confirmed case (odds ratio 2.67, 95% CI 1.48-4.80), reported Katlyn Nemani, MD, of New York University Langone Medical Center in New York, and colleagues.

Schizophrenia is 2nd highest risk factor for dying of COVID-19, after age. By Yasemin Saplakoglu - Staff Writer January 27, 2021.
"It is both expected but also surprising."
Schizophrenia may be one of the highest risk factors for dying from COVID-19, second only to age, according to a new study.
Previous studies had found that people with mental illnesses, particularly depression and schizophrenia — a condition that causes distortions in thinking and perception — had a higher risk of becoming infected with SARS-CoV-2, the virus that causes COVID-19. But it was not known whether mental disorders were also associated with a risk of dying from COVID-19.
In the new study, researchers looked at health records from 260 outpatient clinics and four hospitals across New York City, based on data published by the New York University electronic health record; Of 26,540 patients tested (around 4,500 patients were excluded for various reasons), 7,348 adults tested positive COVID-19 between March 3 and May 31.

2021: Schizophrenia diagnosis among top risk factors for mortality in COVID-19 patients
Schizophrenia spectrum disorder diagnosis appeared to be a significant risk factor for mortality among individuals with COVID-19, according to results of a retrospective cohort study published in JAMA Psychiatry.
“The increased incidence of COVID-19 among individuals with mental disorders has been reported in at least [two] nationwide cohort studies in the US, with depression and schizophrenia associated with the highest infection risk in one sample,” Katlyn Nemani, MD, of the department of psychiatry at New York University Langone Medical Center, and colleagues wrote. “This association may be attributable to socioeconomic and environmental factors that contribute to exposure (eg, crowded housing, institutional settings and lack of personal protective equipment). Because outcomes may differ by diagnosis, it is important to determine which infected patients are at increased risk [for] adverse outcomes.”

2020: Severe mental illness and risks from COVID-19
People living with SMI may also be at risk of worse outcomes from COVID-19 than the general population. A range of clinical syndromes are associated with COVID-19, from asymptomatic or mild disease to severe infection with complications such as acute respiratory distress syndrome, with high associated mortality (15). Risk factors for severe infection are highly prevalent in the SMI population. For example, increased rates of obesity, cardiovascular disease and chronic obstructive pulmonary disease are found in people with SMI (16). In part, this may reflect lifestyle factors, including smoking and physical inactivity, but also is a consequence of psychiatric medication side-effects. In particular, atypical antipsychotics are associated with a metabolic syndrome encompassing weight gain, hyperlipidemia and impaired glucose control (17). These factors have been associated with severe infection with SARS-CoV-2 (16). There are additional concerns relating to clozapine, the gold-standard antipsychotic for treatment-resistant schizophrenia (18). Clozapine is associated with haematological side effects including neutropenia and rarely life-threatening agranulocytosis (19), resulting in cessation of clozapine treatment if white cell counts are less than < 3.0 x 109/L (21). Prior to COVID-19, clozapine treatment has been associated with a higher rate of hospital admissions due pneumonia (although the mechanism is debated) (20). However, there is concern that interruption of clozapine treatment, in the case of low white cell count during SARS-CoV-2 infection, may in fact pose a greater challenge to safely managing a COVID-19 infected patient, due to risk of relapse of their psychotic disorder (22). Theoretical concerns have also been raised about benzodiazepines, which are associated with depression of respiratory function, and COVID-19 infection outcomes (3). Finally, access to healthcare may affect outcomes following infection with SARS-CoV-2 in people with SMI. It has previously been shown that people with SMI experience reduced access to healthcare, for example through delayed presentation, misattribution of symptoms and stigmatising attitudes of health professionals (16).

expert reaction to COVID and schizophrenia
A study as published in JAMA Psychiatry looks at Psychiatric Disorders and mortality among COVID-19 patients.
Prof James MacCabe, Professor of Epidemiology and Therapeutics, Institute of Psychiatry Psychology and Neuroscience, Kings College London, said:
“The increased death rate from COVID-19 in people with schizophrenia is a cause for concern. We know that people with severe mental illness have higher overall mortality and often face reduced access to healthcare. They may be less likely to present to healthcare settings, and may be subject to healthcare rationing in some settings. These disparities in access to healthcare may be especially severe in the USA, where this study was conducted. To put the findings into context, the magnitude of the effect is comparable to that seen in physical health conditions including diabetes and neurological diseases. Crucially, this study did not take obesity into account which may account for some or even all of the effect. The most closely comparable study is probably that conducted in South Korea, which found that people with depression were slightly more likely to die from COVID-19 than schizophrenia, suggesting that these findings may vary in different healthcare systems. It will therefore be important to examine this effect in the UK and to address inequalities in access to healthcare in people with severe mental illness.”
Dr Sameer Jauhar, Senior Research Fellow and JMAS Sim Fellow, Institute of Psychiatry, Psychology and Neuroscience, King’s College London, said:
“We have known for a number of years that people with major mental illness, such as schizophrenia, have decreased life expectancy, which varies depending on the country and health system, and can be as much as 10-15 years less than the general population.
“There is an older literature from around ten years ago, suggesting that people with schizophrenia and pneumonia were almost twice as likely to be admitted to ITU than people with pneumonia who did not have a diagnosis of schizophrenia.
“Therefore the findings of this study, where people with schizophrenia and COVID-19 were more likely to die than the general population and people with other mental illness such as mood and anxiety disorders, are plausible.
“The authors of this study were able to control for a number of factors that may have been associated with this increase mortality risk, such as smoking, heart disease and race.
“It should be borne in mind that the findings are based on data from 75 people with schizophrenia and CO-VID 19, and therefore though plausible, should be interpreted cautiously.
“The authors talk about immune function being compromised, and whilst that may well be the case (and there is a small level of increased risk from genetic studies to support this), there are a myriad of factors that could be at play here, including barriers to accessing care early, and perhaps an interplay between these social factors and vulnerability in this population of people.
“In my opinion this study has practical implications-these are a vulnerable group of people, and should be targeted for vaccines, in much the same way as other people at increased mortality risk from CO-VID 19. Parity for people with severe mental illness has been a slogan for a number of years, and the findings from this study underline this.”

COVID Especially Risky With Schizophrenia
THURSDAY, Jan. 28, 2021 (HealthDay News) -- Schizophrenia is second only to age when it comes to risk factors for dying from COVID-19, new research suggests.
People with this mental illness are known to be at greater risk for contracting COVID-19, but the new study shows they are also more likely to die from this virus.
"Old age is still the most important risk factor for dying of COVID-19, but in our study, schizophrenia surpassed even heart, lung and kidney disease," said study author Dr. Donald Goff, director of the Institute for Psychiatric Research at NYU Langone in New York City.
"We believe that people with schizophrenia should be prioritized in terms of receiving COVID 19 vaccinations and encouraged to observe safety precautions," said Goff, who is also a psychiatry professor at NYU Langone.

Severe mental illness: reassessing COVID-19 vaccine priorities
As evidence mounts that patients with severe mental illness are at increased risk of severe COVID-19, some countries are reassessing their vaccine priority strategies. Nayanah Siva reports.
“The evidence is really very clear. We have well over six studies now published with data from US, the UK, Denmark, and Sweden all showing the same thing”, Livia De Picker, University Psychiatric Hospital Campus Duffel, Antwerp, Belgium, told The Lancet. “Patients with severe mental illness, which is patients with psychotic disorder, bipolar disorder, or severe depression, are at a significantly increased risk of being hospitalised or dying from COVID.”

COVID-19 vaccination for people with severe mental illness: why, what, and how?
Psychiatric disorders, and especially severe mental illness, are associated with an increased risk of severe acute respiratory syndrome coronavirus 2 infection and COVID-19-related morbidity and mortality. People with severe mental illness should therefore be prioritised in vaccine allocation strategies. Here, we discuss the risk for worse COVID-19 outcomes in this vulnerable group, the effect of severe mental illness and psychotropic medications on vaccination response, the attitudes of people with severe mental illness towards vaccination, and, the potential barriers to, and possible solutions for, an efficient vaccination programme in this population.

The most terrifying thing': Some Covid-19 patients are suffering severe psychosis
'There's something happening'
As Belluck explains, while the virus that causes Covid-19 was initially considered primarily a respiratory disease, more and more patients are reporting a host of other symptoms, including neurological, cognitive, and psychological effects. And among these cases is a small but growing number of patients who are experiencing severe "post-Covid psychosis," providers say.
For example, a patient named Ivan Agerton—a 49-year-old documentary photographer living in Seattle, who had no personal or family history of mental illness—began experiencing crippling paranoia and auditory hallucinations weeks after recovering from a mild case of Covid-19. He believed that his neighbors were spying on his family and that police were tracking his movements.
"Like a light switch—it happened this fast—this intense paranoia hit me," Agerton said. "It was really single-handedly the most terrifying thing I've ever experienced in my life."
In another case, Hisam Goueli, a psychiatrist, helped treat a physical therapist in her early 40s who sought help at South Oaks Hospital in New York after she started to hear a voice telling her to kill herself and harm her children. The woman, who had never experienced psychiatric symptoms before, said the symptoms started just months after recovering from a mild case of Covid-19.
Goueli said he was initially unsure whether her case was Covid-related. "But then," he said, "we saw a second case, a third case and a fourth case, and we're like, 'There's something happening.'"
Indeed, while the overall number of these cases remains low—and experts expect the cases to remain rare—the reports aren't merely anecdotal, Belluck reports. A British study of neurological and psychiatric symptoms among 153 Covid-19 patients found that 10 study participants presented with "new-onset psychosis." Similarly, another study identified 10 such patients at a hospital in Spain.
Much about the condition remains a mystery, experts say
While experts don't think this trend is unique to Covid-19—psychotic episodes have sporadically occurred amid other viruses, including the 1918 flu and the SARS and MERS coronaviruses—they note that much about post-Covid psychosis remains a mystery, Belluck writes.
Cheat sheet: Tele-behavioral health
Currently, experts hypothesize that this condition may be associated with how the immune system responds to the virus, including vascular issues or inflammation. "Some of the neurotoxins that are reactions to immune activation can go to the brain, through the blood-brain barrier, and can induce this damage," said Vilma Gabbay, a co-director of the Psychiatry Research Institute at Montefiore Einstein, who has treated two patients with post-Covid psychosis.
As Robert Yolken, a neurovirology expert at Johns Hopkins University School of Medicine, explained, the immune systems of some patients who've physically recovered from Covid-19 remain activated because of "delayed clearance of a small amount of virus."
And that continuing activation of the immune system, according to Emily Severance, an expert in schizophrenia at Johns Hopkins, is currently the leading hypothesis into other brain-related symptoms of Covid-19, such as brain fog and memory loss. It's reasonable to think that post-Covid psychosis may stem from "something similar happening in the brain," she said.
In fact, the variety of symptoms may depend on what part of the brain is affected by the ongoing immune response, Yolken said. He noted that "some people have neurological symptoms, some people psychiatric and many people have a combination."
A different expression of psychosis—and an ambiguous recovery
According to experts, the experience of psychosis among Covid-19 patients seems to differ significantly from how psychosis typically presents.
Webinar series: 'Stay Up to Date' on the latest with Covid-19
For instance, while paranoid delusions typically accompany schizophrenia during late adolescence or dementia in elder adults, post-Covid-19 psychosis so far seems to primarily affect patients in their 30s, 40s, and 50s. "It's very rare for you to develop this type of psychosis in this age range," Goueli said.
In addition, while most people experiencing psychosis generally "don't have insight into their symptoms," several patients with post-Covid psychosis were aware that something was off, according to Veronika Zantop, a psychiatrist who helped treat Agerton.
There's also little consistency in symptoms among those affected by post-Covid-19 psychosis, Belluck writes, although several patients reported experiencing only mild Covid-19. For example, some patients experiencing post-Covid-19 psychosis feel urges to hurt themselves or others, much like Goueli's patient, while others—such as Agerton—experience deep paranoia rather than any violent impulses.
Moreover, while some patients require weeks of hospitalization to identify the right medications, others improve relatively quickly. Goueli's patient, for instance, was hospitalized for four weeks before doctors found a regimen of medicine that alleviated her symptoms and enabled her to return home. She's currently "95% perfect," Goueli said.
And while some patients seem to experience just a one-off episode, others struggle with relapses. For his part, Agerton was hospitalized in a psychiatric ward twice for his psychosis. While he's now returned home and says he's improving, he's still not 100%. "There's this fear of how long is this going to happen," he said. "How long am I going to live with this?"
Ultimately, however, experts hope that studying these individual cases and larger pieces of research can shed light on what remains a challenging and difficult situation. "We don't know what the natural course of this is," Goueli said. "There are just so many unanswered questions" (Belluck, New York Times, 12/28/2020; Belluck, New York Times, 3/22).

COVID-19 and schizophrenia: A potentially deadly combination.
A study conducted in a major New York City hospital system in 2020 found that people with schizophrenia have 2.7 times the overall risk of dying within 45 days if they are infected with the COVID-19 virus. Higher mortality was not seen in people with depression or anxiety who contracted the virus.
People living with schizophrenia are uniquely vulnerable to COVID-19 and completely missing from Canada’s National Advisory Committee on Immunization’s recommendations for vaccine distribution, which prioritizes seniors, front-line health-care workers and Indigenous communities in the first stage.
Those with schizophrenia are almost three times more likely to die from COVID-19 than those without the serious mental illness, making it second only to age as a risk factor for mortality, according to a study in JAMA Psychiatry.
The study included more than 7,000 adults with confirmed COVID-19 in a large New York health system. It found that a pre-existing diagnosis of schizophrenia was significantly associated with an increased risk of death, even after adjusting for other demographic and medical risk factors.
In fact, schizophrenia was found to be a distinct, and more deadly COVID-19 risk factor than heart, lung and kidney disease — even while it is well-established that those with schizophrenia often also have multiple co-morbid conditions, such as COPD or diabetes, that put them at further risk, say advocates.

2019: Is the global prevalence rate of adult mental illness increasing? Systematic review and meta-analysis.
The question whether mental illness prevalence rates are increasing is a controversially debated topic. Epidemiological articles and review publications that look into this research issue are often compromised by methodological problems. The present study aimed at using a meta‐analysis technique that is usually applied for the analysis of intervention studies to achieve more transparency and statistical precision.
