A Rutgers-led international collaboration has identified 36 genes that substantially raise the risk for obsessive-compulsive disorder (OCD) and chronic tic disorders – providing what two researchers said is the most detailed biological understanding of how these conditions develop – and how they might eventually be treated.
Before this study, published in Nature Neuroscience, scientists had found a few genetic clues, each linked separately to OCD or chronic tic disorders.
Results from a clinical trial funded by the National Institutes of Health (NIH) and published today in the journal Lancet Infectious Diseases show that the antiviral drug, PAXLOVID, commonly prescribed to treat acute COVID-19, does not have an impact on Long COVID symptoms when compared to placebo.
Regular aerobic exercise – the kind that gets your heart pumping – can improve important thinking skills called executive functions, and the benefits appear especially strong for women after menopause, according to Rutgers researchers.
