Depression and anxiety are on the rise, surveys suggest. That rise might be especially sharp in people who endured stressful diagnoses, illnesses and isolation.<img src="https://www.sciencenews.org/wp-content/uploads/2021/04/042321_ls_covid_brain_inline3.jpg" alt="clotting protein in postmortem brain from person with COVID-19" class="fr-fic fr-dii fr-draggable " style="" />In a postmortem brain from a person with COVID-19, a clotting protein called fibrinogen (red) indicates that the blood vessels are damaged and leaky.AVINDRA NATHJust being in an intensive care unit can lead to confusion. Delirium affected 606 of 821 people — 74 percent — while patients were in intensive care units for respiratory failure and other serious emergencies, a 2013 study found. Post-traumatic stress disorder afflicted about a third of people who had been seriously sick with COVID-19 (SN: 3/12/21).More specific aspects of treatment matter too. COVID-19 patients who spent long periods of time on their stomachs might have lingering nerve pain, not because the virus attacked the nerve, but because the prone position compressing the nerves. And people might feel mentally fuzzy, not because of the virus itself, but because a shortage of the anaesthetic drug, propofol, meant they received an alternative sedative that can bring more aftereffects, says Rogers, the psychiatrist at University College London.Lingering questions — what the virus actually does to the brain, who will suffer the most, and for how long — are still unanswered, and probably won’t be for a long time. The varied and damaging effects of lockdowns, the imprecision doctors and patients use for describing symptoms (such as the nonmedical term “brain fog”) and the indirect effects the virus can have on the brain all merge, creating a devilishly complex puzzle.For now, doctors are busy focusing on ways in which they can help, even amid these mysteries, and designing larger, longer studies to better understand the effects of the virus on the brain. That information will be key to helping people move forward. “This isn’t going to be over soon, unfortunately,” Troyer says.  By Laura Sanderssciencenews.org</blockquote>
