![]() Last week, a study from the Yale School of Medicine and the Icahn School of Medicine at Mount Sinai found lower rates of cortisol, a stress hormone, in those with long COVID. Catching the disease has been tied to chronic fatigue, muscle weakness, hair loss, erectile dysfunction, stroke, and cardiovascular illness. Scientists are still investigating just how broadly COVID affects the body. The research also did not examine how vaccination altered the chance of developing a neurological condition, but referred to earlier work by some of the authors that found that vaccination reduced the risk of psychotic disorders, while leaving the risk of anxiety and depression unchanged. The study only analyzed patients whose COVID diagnosis was entered into their medical record, and so may not reflect those who never sought professional medical care for COVID, such as those who were asymptomatic or had mild symptoms. ![]() The study found that despite lower death rates, new variants showed “similar” risks of “neurological and psychiatric outcomes” as earlier strains. New variants, like the more transmissible but less deadly Omicron variant, did not seem to change the risk of developing one of these conditions. Children were not found to have an increased risk of mood or anxiety disorders compared to non-COVID patients. The risk of ‘brain fog’ returned to a baseline level after about two months, but the chance of developing other conditions like epilepsy remained elevated after two years. That risk returned to baseline levels within a few months, and both COVID and non-COVID patients reported equal incidences of these conditions within 15 months.Ĭhild COVID patients also had an increased chance of developing conditions like brain fog, insomnia, and other disorders following a COVID-19 diagnosis. The study also uncovered an increased risk of mood and anxiety disorders in the weeks following a diagnosis of COVID-19. For conditions like cognitive deficit, dementia, epilepsy, insomnia, and psychotic disorder, the risk never returned to the baseline level by the end of the studied time period. ![]() Researchers also tracked when the chance of developing one of thes e conditions would return to the same level as non-COVID patients. In particular, COVID patients were 36 times more likely to be diagnosed with cognitive deficit and 33 times more likely to be diagnosed with dementia six months after catching COVID. The study found that COVID patients were 13 times more likely to be diagnosed with any one of 14 tracked neurological conditions six months after catching the disease, compared to patients of other respiratory diseases. Researchers compared COVID patients to an equal number of patients diagnosed with a non-COVID respiratory infection, who acted as a control group. Researchers analyzed data from almost 1.5 million COVID patients sourced from TriNetX, which compiles health records from 89 million patients across eight countries. The study, published in The Lancet Psychiatryon Wednesday, found that the risk of disorders like cognitive deficit (also known as ‘brain fog’), psychotic disorders, and epilepsy was elevated even two years after a COVID diagnosis. ![]()
