St. PAUL, Minn., May 15 (UPI) -- Millions of "long COVID" patients coping with debilitating "brain fog" and chronic fatigue, who are looking for answers to what's at the root of their illness, received a hopeful sign through a new study released Thursday.
The answers, though somewhat complex, appear to be biological and neurological, authors of the study said. In other words, it's not just in patients' heads.
An estimated 12 million COVID "long-haulers" in the United States experience a range of neurological symptoms such as feeling slow, having difficulty thinking or concentrating, confusion and forgetfulness many months after recovery from the viral infection.
Sufferers have reported up to 200 different symptoms, both mental and physical, the most common of which include brain fog, lingering fatigue and shortness of breath.
