PET reveals visual brain pattern of long COVID


Dr. Rob’s comment: Many individuals report ongoing neurological problems after COVID, especially after more severe cases. A PET study in 143 individuals has identified the metabolic fingerprint of long COVID in the brain, involving decreased activity in the olfactory and limbic areas, and the pons and cerebellum. These brain areas relate to frequently reported problems in loss of smell, emotional disturbance, reduced memory, balance impairment, and autonomic disturbances like sudden high heart rate.
