LONDON, April 7: One in three COVID-19 survivors in a study of more than 230,000 mostly American patients were diagnosed with a brain or psychiatric disorder within six months, suggesting the pandemic could lead to a wave of mental and neurological problems, scientists said on Tuesday.

Neurological symptoms can linger as long-term effects after COVID-19, but one in particular is becoming known as "COVID-19 brain fog." Though it can manifest in different ways, the reports are concerning: a nurse can't remember what patients say once she leaves the room, one vascular medicine specialist has lost chunks of time from his memory (he couldn't recall a 12-day vacation weeks earlier), and a lawyer can't recognize her own car.
