Long after a Covid-19 infection, mental and neurological effects smolder

Even people who were never sick enough to go to a hospital, much less lie in an ICU bed with a ventilator, report feeling something as ill-defined as “Covid fog” or as frightening as numbed limbs. They’re unable to carry on with their lives, exhausted by crossing the street, fumbling for words, or laid low by depression, anxiety, or PTSD. As many as 1 in 3 patients recovering from Covid-19 could experience neurological or psychological after-effects of their infections, experts told STAT, reflecting a growing consensus that the disease can have lasting impact on the brain. Beyond the fatigue felt by “long haulers” as they heal post-Covid, these neuropsychological problems range from headache, dizziness, and lingering loss of smell or taste to mood disorders and deeper cognitive impairment. Dating to early reports from China and Europe, clinicians have seen people suffer from depression and anxiety. Muscle weakness and nerve damage sometimes mean they can’t walk.
