Analysis of brain images taken before and after infection with SARS-CoV-2 suggests that even mild COVID-19 is associated with brain structure alterations and cognitive impairment. However, the clinical implications for individuals are unclear and further studies are needed to assess the ...
Imaging before and after infection by the SARS-CoV-2 virus reveals substantial changes in the brain after infection. The work sets an example for the high standards required in large longitudinal neuroimaging studies. By Randy L. Gollub
3. Detecting cognitive changes in longitudinal studies demands the use of more advanced tests than the MoCA (1). Although the authors clearly stated that they study brain health was conducted after severe acute COVID-19, it is important to remember that most brain health changes after COVID-19...
Quite a few studies now indicate cognitive changes after COVID-19 illness. The cognitive problems mainly include memory, attention, executive function, processing speed, and visuospatial deficits, but may also include other brain functions. The research indicates that cognitive impairments ca...
Long Covid can also develop after milder infections. But the research team, from the universities of Oxford and Leicester, stress: *Their findings are relevant only to patients admitted to hospital *They are “the first piece of the jigsaw” but further research is needed before they can propo...
However, months of anxiety, grief and loneliness can easily create a spiral of negativity that is hard to break out of. That's because chronic stress changes thebrain. And sometimes when we're low we have no interest in doing the things that could actually make us feel better. ...
COVID-19 has been associated mostly with problems like difficulty breathing, fever and cough. However, as the pandemic has continued, it has become increasingly clear that other problems can occur in patients. These include confusion, stroke, inflammation of the brain,spinal cord, and other kinds...
after some had either medical and public health records of COVID-19, or had tested positive for SARS-CoV-2 twice using rapid antibody tests. Those participants were then matched with control individuals who had undergone the same longitudinal imaging protocol but had tested negative using the rapi...
Researchers, clinicians, and the public all are eager to learn more about COVID-19’s outcomes after the initial infection, especially for individuals with mild or asymptomatic disease, which represents most people with SARS-CoV-2 infection. Of particular interest are brain-related changes that cou...
After initial COVID-19 infection, approximately 20% of patients experience persistent symptoms for more than 4 weeks. This clinical phenomenon is often termed "long COVID" but many other terms exist in the literature including "Post-COVID-19 syndrome," "Chronic COVID-19," "long haul COVID,...
