A new study published in Psychiatry Research explores the relationship between fatigue in Long COVID and specific patterns of brain connectivity. Researchers observed that fatigue, one of the most common and debilitating symptoms in Long COVID patients, is associated with certain patterns of brain structure and function, particularly in the frontal and cerebellar regions. Notably, mental and physical fatigue were linked to distinct brain connectivity patterns, suggesting the possibility that different neural mechanisms may be involved in each type of fatigue. Long COVID, also known as post-COV…
