Dopaminergic Vulnerability in Long COVID: Why Dopamine May Be the Missing Link Between the Brain and the Body
Understanding the New eBioMedicine Editorial A recent editorial published in eBioMedicine , "Dopaminergic Vulnerability in Long COVID: Striatal PET Imaging at the Brain–Body Interface," highlights an emerging area of neuroscience that may fundamentally change how researchers understand Long COVID. The editorial discusses growing evidence that the dopaminergic system—the network of neurons responsible for producing and regulating dopamine—may be particularly vulnerable following SARS-CoV-2 infection. For millions of people living with Long COVID, symptoms such as profound fatigue, brain fog, poor concentration, depression, reduced motivation, autonomic dysfunction, movement abnormalities, and exercise intolerance have often appeared disconnected. However, the dopaminergic system provides a possible biological explanation that links many of these symptoms into a single neurological framework. Rather than suggesting that Long COVID is simply a disorder of one organ, this resear...
