Taquet, M. et al. Nat. Outcomes were ascertained 30 d after the COVID-19-positive test until the end of follow up. It is imperative that we recognize the enormous challenges posed by Long Covid and all its downstream long-term consequences. The participants with long COVID reported their current cognitive issues: 78% reported difficulty concentrating. Burdens are presented per 1,000 persons at 12 months of follow up. The thing that bothered me the most was that I was really having trouble thinking, speaking, rememberingtrying to complete a task and having no idea what it was. We leveraged the breadth and depth of the national healthcare databases of the US Department of Veterans Affairs to build a large cohort of 154,068 people who had COVID-19 and more than 11 million people in the control group. The dashed line marks a HR of 1.00; lower limits of 95% CIs with values greater than 1.00 indicate significantly increased risk. Her early infection and ongoing symptoms make her one of the first people in the country with long COVID, a condition where symptoms persist for at least three months after the infection and can last for years. Both predefined and algorithmically selected covariates were used in the modeling and were assessed in the year before T0. Continuous variables were transformed into restricted cubic spline function to account for potential nonlinear relationships. 7 The risks of incident postacute COVID-19 composite neurologic outcomes across age compared with the historical control cohort. Z.A.A. Burdens are presented per 1000 persons at 12 months of follow up. Xie, Y., Bowe, B. Alzheimer's-like signaling in brains of COVID-19 patients. She tells people their bodies can heal themselves if the patients and clinicians find the right tools. Nervous system consequences of COVID-19. 12, 27762797 (2021). https://doi.org/10.1038/s41591-022-02001-z, DOI: https://doi.org/10.1038/s41591-022-02001-z. Adjusted HRs (dots) and 95% (error bars) CIs are presented, as are estimated excess burdens (bars) and 95% CIs (error bars). & Al-Aly, Z. The Mount Sinai Health System was among the first to create a Center for Post-COVID Care. Knowledge awaits. Burdens are presented per 1000 persons at 12 months of follow up. COVID-19 cohort (n=154,068) and historical control cohort (n=5,859,621). This places more emphasis on the continued need for multipronged primary prevention strategies through nonpharmaceutical interventions (for example, masking) and vaccines to reduceto the extent possiblethe risk of contracting SARS-CoV-2. Composite outcomes consisted of cerebrovascular disorders (ischemic stroke, TIA, hemorrhagic stroke, and cerebral venous thrombosis), cognition and memory (memory problems and Alzheimers disease), disorders of the peripheral nerves (peripheral neuropathy, paresthesia, dysautonomia, and Bells palsy), episodic disorders (migraine, epilepsy and seizures, and headache disorders), extrapyramidal and movement disorders (abnormal involuntary movements, tremor, Parkinson-like disease, dystonia, myoclonus), mental health disorders (major depressive disorders, stress and adjustment disorders, anxiety disorders, and psychotic disorders), musculoskeletal disorders (joint pain, myalgia, and myopathy), sensory disorders (Hearing abnormalities or tinnitus, vision abnormalities, loss of smell, and loss of taste), other neurologic or related disorders (dizziness, somnolence, Guillain-Barr syndrome, encephalitis or encephalopathy and transverse myelitis), and any neurologic outcome (incident occurrence of any neurologic outcome studied). J. Clin. PubMed Even if it's 15 percent less, the total population of patients is still growing and exploding, Pittman says. Nephrol. Altogether, our results show that the risks and burdens of neurologic disorders in the COVID-19 group at 12 months are substantial. Those alive after 30 days after the start of follow up (n=5,638,795) were selected as the contemporary control cohort. She gets exhausted quickly, her heartbeat suddenly races, and she goes through periods where she can't concentrate or think clearly. Long Covid, in contrast, affects anywhere from about 5% to 30% of those infected by SARS-CoV-2. We investigated a comprehensive list of prespecified neurologic outcomes. Among Ghormley's toughest symptoms is her brain fog, a catchall term for a slew of cognitive problems that make it hard for her to function. 6. Within the COVID-19 cohort, nonhospitalized (n=131,915), hospitalized (n=16,764), admitted to intensive care (n=5,389) and historical control cohort (n=5,809,908). COVID-19 cohort (n=154,068) and historical control cohort (n=5,859,621). It's estimated that more than a third of people who have had COVID-19 also have neurological complications such as brain fog that persist or develop 3 months after infection. Acute COVID-19 infection can sometimes lead to long-lasting effects, that have collectively been termed "Long Covid," and can include a wide variety of symptoms in the brain and nervous system that range from a loss of taste and smell, impaired concentration, fatigue, pain, sleep disorders, autonomic disorders and/or headache to . Direct invasion of the virus into the central nervous system has also been proposed as a putative hypothetical mechanism of neuronal injury22. 32,33,35). provided supervision and mentorship. CAS Neurol. Risks and burdens were assessed at 12 months in mutually exclusive groups comprising nonhospitalized individuals with COVID-19 (green), individuals hospitalized for COVID-19 (orange) and individuals admitted to intensive care for COVID-19 during the acute phase (first 30 days) of COVID-19 (purple). 168, 656664 (2008). Since COVID-19 can impact so many parts of the body, it can cause a wide range of symptoms. But those, too, result from nerve dysfunction, often in the autonomic nervous system, which directs our bodies to breathe and digest food and generally runs our organs on autopilot. The estimated probability (P(group=observed group|L)) was used as the propensity score to calculate the inverse probability weight for average treatment effect within the cohort. Sensory disorders included hearing abnormalities or tinnitus (HR 1.22 (1.18, 1.25); burden 11.87 (10.05, 13.75)), vision abnormalities (HR 1.30 (1.24, 1.36); burden 5.59 (4.55, 6.68)), loss of smell (HR 4.05 (3.45, 4.75)); burden 1.07 (0.86, 1.32)) and loss of taste (HR 2.26 (1.54, 3.32); burden 0.11 (0.05, 0.21)). We estimated the risks of a set of prespecified neurologic outcomes in COVID-19 versus the contemporary control group; we also estimated the adjusted excess burden of neurologic outcomes due to COVID-19 per 1,000 persons at 12 months on the basis of the difference between the estimated incidence rate in the COVID-19 and contemporary control groups. "The language that we as psychologists speak, and the capacity we have, is hitting COVID survivors exactly where they live." Post-COVID Care: A Neurologist's Perspective. Although we adjustedthrough weightingfor predefined and algorithmically selected covariates, and although we used validated definitions for outcomes, and our results were robust to challenge in sensitivity analyses and survived the scrutinous application of negative controls, we cannot completely rule out misclassification bias or residual confounding. (2) Our interaction analyses suggest that the effect of COVID-19 on risk of memory and cognitive disorders, sensory disorders and other neurologic disorders (including GuillainBarr syndrome and encephalitis or encephalopathy) is stronger in younger adults; the effects of these disorders on younger lives are profound and cannot be overstated; urgent attention is needed to better understand these long-term effects and the means to mitigate them. Multisystem involvement in post-acute sequelae of coronavirus disease 19. Risks and burdens of the composite endpoints are provided in Fig. Slider with three articles shown per slide. There's dysregulation of the nervous system, and so many things can cause it: some cancer therapies, viruses, autoimmune conditions. Agarwal recognized POTS in Ghormley in the fall of 2020, when very little was known about long COVID. Governments and health systems should take into account the findings that SARS-CoV-2 leads to long-term neurologic (and other serious) consequences when devising policy for continued management of this pandemic and developing plans for a postpandemic world. Most of the first recognized cases of long COVID were in patients who needed extended respiratory therapy or who had obvious organ damage that caused lasting symptoms. 2023 Scientific American, a Division of Springer Nature America, Inc. Adjusted HRs (dots) and 95% (error bars) CIs are presented, as are estimated excess burdens (bars) and 95% confidence intervals (error bars). The historical control cohort served as the referent category. Zhang, L. et al. Clues about the inflammatory processes at work could point toward treatments for neurological symptoms. But as 2020 came to an end, says Helen Lavretsky, a psychiatrist at the University of California, Los Angeles, we started getting to a place of sorting through what was really going on and it became very evident at that time that neuropsychiatric symptoms were quite prevalent, most commonly fatigue, malaise, brain fog, smell loss and post-traumatic stress disorder, as well as cognitive problems and even psychosis. CAS The clinic grew out of a program aimed at coordinating care for medically complex COVID patients, says its director Nisha Viswanathan, an internist and primary care physician. Assessment of standardized mean differences after application of inverse weighting suggested that covariates were well balanced (Extended Data Fig. The findings were consistent in comparisons involving the contemporary control group and the historical control group. 2 and Supplementary Table 3 and are discussed below. We then used cause-specific hazard models where death was considered as a competing risk to estimate hazard ratios of incident neurologic outcomes between the COVID-19 and contemporary cohorts and the COVID-19 and historical cohorts after application of inverse probability weights. NPR's Scott Simon talks with Dr. Leora Horwitz of NYU Langone Health about what we now understand about long COVID and its treatments. Adjusted HRs (dots) and 95% (error bars) CIs are presented, as are estimated excess burdens (bars) and 95% confidence intervals (error bars). & Vassall, A. I can't tell you the number of times I was told it was in my head., In addition to drugs, other types of therapies, including physical therapy, can help improve some symptoms. I want you to know that everything you're feeling is real, and I've seen so many patients like you. And she started crying. The respective risk and burden of a composite of these mental health disorders were 1.43 (1.38, 1.47) and 25.00 (22.40, 27.69). Composite outcomes consisted of cerebrovascular disorders (ischemic stroke, TIA, hemorrhagic stroke and cerebral venous thrombosis), cognition and memory disorders (memory problems and Alzheimers disease), disorders of the peripheral nerves (peripheral neuropathy, paresthesia, dysautonomia and Bells palsy), episodic disorders (migraine, epilepsy and seizures, and headache disorders), extrapyramidal and movement disorders (abnormal involuntary movements, tremor, Parkinson-like disease, dystonia, myoclonus), mental health disorders (major depressive disorders, stress and adjustment disorders, anxiety disorders, and psychotic disorders), musculoskeletal disorders (joint pain, myalgia and myopathy), sensory disorders (hearing abnormalities or tinnitus, vision abnormalities, loss of smell and loss of taste), other neurologic or related disorders (dizziness, somnolence, GuillainBarr syndrome, encephalitis or encephalopathy and transverse myelitis) and any neurologic outcome (incident occurrence of any neurologic outcome studied). We're trying to sort through long COVID patients and say, This would be a good group to take to trials of an anti-inflammatory drug, whereas this group may need to focus more on rehabilitation, Torgerson says. 1). contributed to critical revision of the manuscript. This so-called dysautonomia can lead to dizziness, a racing heart, high or low blood pressure, and gut disturbances, sometimes leaving people unable to work or even function independently. Research on other viruses, and on neurological damage from the human immunodeficiency virus (HIV) in particular, is guiding work on long COVID. Risks and burdens were assessed at 12 months in mutually exclusive groups comprising nonhospitalized individuals with COVID-19 (green), individuals hospitalized for COVID-19 (orange) and individuals admitted to intensive care for COVID-19 during the acute phase (first 30 d) of COVID-19 (purple). These could include signs of inflammation or certain molecules. She mostly recovered from this acute phase within a few weeks, but, she says, I never really got better., Soon after coming home from the hospital, Ghormley developed what her husband called goldfish brain. I'd put something down and have no idea where I put it, she recalls. And a therapy called rituximab that targets antibody-producing B cells provides a time-tested therapy for a lot of autoantibody-mediated syndromes, Nath says. Outcomes were ascertained 30d after the COVID-19-positive test until the end of follow up. Outcomes were ascertained 30d after the COVID-19-positive test until the end of follow up. SCOTT SIMON, HOST: On March 13, 2020, then-President Donald . Even though her symptoms are rooted in nervous system dysfunction, she needed an array of medical specialists to treat them. Composite outcomes consisted of cerebrovascular disorders (ischemic stroke, TIA, hemorrhagic stroke and cerebral venous thrombosis), cognition and memory (memory problems and Alzheimers disease) disorders, disorders of the peripheral nerves (peripheral neuropathy, paresthesia, dysautonomia and Bells palsy), episodic disorders (migraine, epilepsy and seizures, and headache disorders), extrapyramidal and movement disorders (abnormal involuntary movements, tremor, Parkinson-like disease, dystonia, myoclonus), mental health disorders (major depressive disorders, stress and adjustment disorders, anxiety disorders, and psychotic disorders), musculoskeletal disorders (joint pain, myalgia and myopathy), sensory disorders (hearing abnormalities or tinnitus, vision abnormalities, loss of smell and loss of taste), other neurologic or related disorders (dizziness, somnolence, GuillainBarr syndrome, encephalitis or encephalopathy and transverse myelitis) and any neurologic outcome (incident occurrence of any neurologic outcome studied). The dashed line marks a HR of 1.00; lower limits of 95% CIs with values greater than 1.00 indicate significantly increased risk. 28, 583590 (2022). In Part 2 of this series, we take a closer look. The contemporary control cohort served as the referent category. Because of the broad nature of the neurologic sequelae of SARS-CoV-2, variousand not necessarily mutually exclusivemechanisms may be at play for different neurologic disorders; these mechanisms may accelerate progression of pre-existing subclinical disease or result in de novo disease31. Some studies have offered more conservative numbers. The road to addressing Long Covid. Ziyad Al-Aly. Nevertheless, 'long-COVID' is conceptualized as a multi-organ disorder with a wide spectrum of clinical manifestations that may be indicative of underlying pulmonary, cardiovascular, endocrine, hematologic, renal, gastrointestinal, dermatologic, immunological, psychiatric, or neurological disease. BMJ 371, m4677 (2020). 3b,c). Researchers are examining inflammatory signals in patients with long COVID in increasingly fine detail. PubMed Google Scholar. 28, 14611467 (2022). To further reduce the influence of extreme weights, the stabilized weights were truncated at 30 (refs. Bowe, B., Xie, Y., Xu, E. & Al-Aly, Z. Kidney outcomes in Long COVID. Google Scholar. Extended Data Fig. In recognition that our knowledge of COVID-19 is evolving and incomplete, we used a dual-pronged approach to identify covariates: (1) we selected covariates based on previous knowledge1,3,5,6,7,8,9,10,11,12,13,22,36,45,46,47,48,49; (2) we used an algorithmic approach to identify covariates in several data domains including diagnoses, medications and laboratory test results. Lavretsky adds that lifestyle choices can play a huge role in improvement, particularly better sleep habits and the use of breathing exercises to control anxiety. Soc. In the meantime, to ensure continued support, we are displaying the site without styles Boldrini, M., Canoll, P. D. & Klein, R. S. How COVID-19 affects the brain. Thanks for reading Scientific American. The autopsy study of 44 people who died of COVID found rampant inflammation mainly in the respiratory tract, but viral RNA was detected throughout the body, even in the brain, as long as 230 days after infection. JAMA 324, 603605 (2020). Post-COVID conditions may not affect everyone the same way. 18, e1003773 (2021). Nobody knew anything about it, but everyone listened to me, Ghormley says. Eur. Health systems should consider these findings in capacity planning and in designing clinical care pathways to address the care needs of people who survive the acute phase of COVID-19. 2 The risks of incident postacute COVID-19 composite neurologic outcomes across age compared with the contemporary control cohort. Persistent symptoms in patients after acute COVID-19. We hypothesized that exposure to the influenza vaccine in odd-numbered or even-numbered calendar days between 1 March 2020 and 15 January 2021 would be associated with similar risks of all the neurologic outcomes examined in our analyses. J. Epidemiol. The VHAa branch of the US Department of Veterans Affairsoperates the largest nationally integrated healthcare system within the US consisting of 1,255 healthcare facilities (including 170VA healthcare systems and 1,074 outpatient sites). The contemporary control cohort served as the referent category. This algorithmic selection process for high-dimensional covariates was conducted independently for each outcome-specific cohort. To date, most studies examining postacute COVID-19 clinical neurologic disorders were limited to people who were hospitalized during the acute phase of COVID-19, and all studies had follow-up duration of less than 6 months with a narrow selection of neurologic outcomes3,4,5,6,7,8. Successful application of these negative outcomes and negative-exposure controls might reduce concern about the presence of spurious biases related to study design, covariate selection, analytic approach, outcome ascertainment, residual confounding and other potential sources of latent biases53. One day last year she skipped a dose of her heart medication and made a Target run in the southern California heat. Investig. Age was transformed into restricted cubic spline function for the analyses. This is not a psychological or psychosomatic disorder; this is a neuroimmune disorder.. A diagnostic routine for the detection of consequential heterogeneity of causal effects. A June 2022 survey reported by the U.S. National Center for Health Statistics found that among adults who had had COVID, one in five was experiencing long COVID three months later; the U.K. Office for National Statistics put the estimate at one in 10. Sometimes the symptoms can even go away or come back again. Mild respiratory COVID can cause multi-lineage neural cell and myelin dysregulation. 32, 33883414 (2013). Long COVID is linked to reduced oxygen uptake in the brain, a new study reports. 3 and Supplementary Table 3. We show increased risk of an array of neurologic disorders spanning several neurologic disease categories including stroke (both ischemic and hemorrhagic), cognition and memory disorders, peripheral nervous system disorders, episodic disorders, extrapyramidal and movement disorders, mental health disorders, musculoskeletal disorders, sensory disorders, and other disorders including GuillainBarr syndrome, and encephalitis or encephalopathy. Early research identified markers that often are elevated in people with the condition, says Troy Torgerson, an immunologist at the Allen Institute in Seattle. Our estimates of the risk of cerebrovascular disorders are generally consistent with our prior report (which was focused on investigating cardiovascular outcomes and included cerebrovascular disorders); minor differences in estimates of risk and burden are likely due to updated analytic approach and the longer follow up time (generally 60 more days of follow up in this current study)18. J. Neurol. If I try to move around, my legs give out. Most frustratingand scaryto Ghormley is the unpredictability of her symptoms. I have patients whose symptoms have disappeared in the course of a year, or they disappear and occasionally flare up again. But for some, she says, it could last many years., We're going to be addressing this for probably decades, Viswanathan says. We investigated these associations in COVID-19 versus a contemporary cohort exposed to the broader contextual changes brought on by the pandemic, and a historical cohort from an era undisturbed by the pandemic. Spudich, S. & Nath, A. PubMed Central The P value for cerebrovascular disorders=0.57, cognition and memory disorders=0.009, disorders of the peripheral nerves=0.04, episodic disorders<0.001, extrapyramidal and movement disorders=0.05, mental health disorders<0.001, musculoskeletal disorders<0.001, sensory disorders<0.001, other neurologic or related disorders=0.002, and any neurologic disorder<0.001. Primary Handling Editor: Ming Yang, in collaboration with the Nature Medicine team. Taken together, our results provide evidence of increased risk of long-term neurologic disorders in people who had COVID-19. The burdens per 1,000 participants at 12 months of follow up in the COVID-19 and control groups were estimated based on the survival probability at 12 months within each group; excess burdens were computed based on the difference of the estimated burdens between COVID-19 and control groups. While most patients did report. But brain inflammation is probably not caused by the virus infecting that organ directly. Nat. Outcomes were ascertained 30 days after the COVID-19-positive test until the end of follow up. PubMed This study used electronic health records from the VA Corporate Data Warehouse (CDW). In following up with COVID patients after several months, she realized that we had a group of patients who still had symptoms. ME/CFS has been difficult to study because it often arises long after a mild infection, making it hard to identify a viral trigger. Epidemiology 20, 512522 (2009). Ann. We then examined the risk and burden of having any neurologic outcome (defined as the occurrence of any incident prespecified neurologic outcome included in this study). ISSN 1078-8956 (print). Several mechanisms have been proposed to explain the postacute sequelae of COVID-19; these include persistence of the virus, RNA fragments or viral proteins leading to continued activation of the immune system and chronic inflammation; other mechanisms may involve autoimmunity, microbiome dysbiosis and organ injury during the acute phase that may result in postacute manifestations19,20,21,22,23,24,25. These post-acute effects usually include fatigue in combination with a series of other symptoms. One of the patterns we see is patients who definitely meet the criteria for ME/CFS. Morgan, S. L. & Todd, J. J. The team approach has also been critical for doctors trying to understand a brand-new disease, Pittman says. Whether that's true for everyone remains to be seen, Viswanathan says. Baseline characteristics in the COVID-19, contemporary and historical control groups and standardized mean differences were described. The dashed line marks a HR of 1.00; lower limits of 95% CIs with values greater than 1.00 indicate significantly increased risk. The risk appears at least slightly higher in people who were hospitalized for COVID and in older adults (who end up in the hospital more often). A small study led by Joanna Hellmuth, a neurologist at U.C.S.F., found that patients with cognitive symptoms had immune-related abnormalities in their cerebrospinal fluid, whereas none of the patients without cognitive symptoms did. Internet Explorer). Long-term neurologic outcomes of COVID-19, https://doi.org/10.1038/s41591-022-02001-z. Post- COVID-19 syndrome involves a variety of new, returning or ongoing symptoms that people experience more than four weeks after getting COVID-19. Outcomes were ascertained 30 d after the COVID-19-positive test until the end of follow up. The treatment, referred to as IVIg, contains a cocktail of proteins and antibodies that can mitigate an overactive immune response. Med. Supplementary Table of Contents and Tables 116. Across 102 long COVID studies, neurologic. A neurological disorder, peripheral neuropathy is a general term for damage to . Nephrol. The dashed line marks a HR of 1.00; lower limits of 95% CIs with values greater than 1.00 indicate significantly increased risk. BMJ 376, e068993 (2022). Incident individual and composite neurologic outcomes during the postacute phase of COVID-19 were assessed during the follow-up period between the 30 days after T0 until the end of follow up in those without any history of the specified outcome in the year before T0. And two-thirds of. We examined the associations in clinically important subgroups and across the spectrum of care during the acute phase of COVID-19 (nonhospitalized, hospitalized and admitted to intensive care). Using the approach outlined in the previous paragraph, inverse probability weights were estimated for each care setting group. What Is Long COVID? A number of people, Viswanathan says, benefit from reducing various treatments they have accumulated. Tachycardiathe T in POTScauses the heartbeat to speed up, contributing to exhaustion and fatigue in addition to stressing the heart itself. Burdens are presented per 1,000 persons at 12 months of follow up. In some people, post- COVID-19 syndrome lasts months or years or causes disability. We employed a longitudinal observational study design and used inverse probability weighting to balance the cohorts, and estimated the risks and burdens at 12 months of a set of prespecified neurologic outcomes in the overall cohort and by care setting of the acute phase of COVID-19 (nonhospitalized, hospitalized and admitted to intensive care). Direct SARS-CoV-2 infection of the human inner ear may underlie COVID-19-associated audiovestibular dysfunction. Many people recover fully within a few days or weeks after being infected with SARS-CoV-2, the virus that causes COVID-19. This study used data from the VA COVID-19 Shared Data Resource. Burdens are presented per 1000 persons at 12 months of follow up. Tara Ghormley has always been an overachiever. Science 373, 491493 (2021). COVID-19 cohort (n=154,068) and contemporary control cohort (n=5,638,795). More than 2 years into the COVID-19 global pandemic, it is abundantly clear that infection with SARS-CoV-2 may result in a broad array of long-term disorders9,10,11,12,13,14.
