COVID reduces brain's happiness hormone for years

COVID reduces brain's happiness hormone for years

A recent study has shown that a COVID-19 infection can leave long-lasting effects on the brain, which can be detected through tests even years after recovery, particularly in those suffering from "long COVID" syndrome. The study revealed that patients experiencing symptoms such as depression after infection exhibit approximately an 18% reduction in dopaminergic nerve endings, a neurotransmitter responsible for controlling movement, motivation, and cognitive functions. The research focused on critical areas of the brain, especially the striatum, where a decline in nerve endings was observed, linked to decreased motivation, memory impairment, and slowed movements. These changes persisted for up to 4.6 years, indicating long-term effects. Millions of people worldwide are suffering from long COVID symptoms, and researchers hope that these findings will contribute to the development of more effective treatments to address these enduring neurological impacts.
