LONG COVID’s BRAIN SYMPTOMS MAY BE RELATED TO LOW BRAIN DOPAMINE
Patients with long COVID have described neurologic symptoms like brain fog, memory problems, difficulty concentrating, and lack of motivation. A new study suggests these symptoms may be related to measurable changes in the brain’s dopamine system. The lower levels were in the region of the brain called the striatum, which plays key roles in reward and motivation, movement and motor control, and cognition—the brain’s ability to think and process information.
