Gut Feelings: New Research Links OCD Origins to Microbiome, Not Just the Brain
A groundbreaking new study suggests that obsessive-compulsive disorder (OCD), a condition that has long baffled mental health experts, may have roots that extend far beyond the brain—down into the gut. Researchers in China have discovered compelling evidence that the bacteria living in our digestive systems, collectively known as the gut microbiota, could play a direct causal role in the development of OCD. This insight has the potential to reshape our understanding of a disorder that affects up to 3 percent of people worldwide and has proven notoriously difficult to treat effectively (ScienceAlert).
