The findings, printed Dec. 9 within the journal Neurology Clinical Practice, are primarily based on sufferers seen earlier within the pandemic.
At this level, docs have realized extra about managing COVID, in methods that may assist stop neurologic issues, mentioned Dr. Aaron Glatt, a spokesperson for the Infectious Diseases Society of America.
That consists of utilizing drugs like corticosteroids and remdesivir, and medicines to stop blood clots.
Glatt identified that the sufferers on this examine had been a choose group — these sick sufficient to require a neurological seek the advice of within the hospital. And of the 74 sufferers, 47 had a historical past of neurological circumstances.
“This isn’t looking at all comers,” famous Glatt, who wasn’t a part of the examine.

Doctors worldwide have been reporting seeing sufferers with lingering fatigue and what’s been dubbed “brain fog” — issues with reminiscence, focus and different psychological abilities.
The abbreviated time period ADHD denotes the situation generally often called:
“There’s a false sense of security among younger people, that COVID is only a risk to older people who end up in the hospital,” Glatt mentioned.
