Brain scans reveal a possible cause of long COVID fatigue and brain fog

Researchers have discovered that long COVID may damage dopamine-releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. This groundbreaking finding, revealed through advanced brain imaging, provides the first neurological evidence of how the virus affects cognitive and physical function long after the acute infection resolves. The damage to the dopamine system—a critical neurotransmitter involved in motivation, movement, and memory—could explain why many long COVID patients struggle with debilitating fatigue that doesn't improve with rest. This discovery opens new avenues for targeted treatments that could restore dopamine function and significantly improve quality of life for the millions suffering from long COVID symptoms.
