Genes Linked to OCD & Tics: New Treatment Hope

Scientists have identified 36 genes that significantly elevate the risk for obsessive-compulsive disorder (OCD) and chronic tic disorders, potentially revolutionizing treatment development. These newly discovered genes often overlap between the conditions, suggesting shared biological pathways in the brain. This finding moves beyond targeting individual genes to addressing entire networks, which could simplify the design of new therapies.

In a separate breakthrough, researchers have pinpointed a protein, EFHD1, within liver cell mitochondria that appears to drive damage in fatty liver disease. This condition affects hundreds of millions globally, but only a fraction develop severe scarring. Blocking EFHD1 has demonstrated a protective effect against liver injury in both laboratory human cells and mice on a high-fat diet. The discovery may lead to targeted drug development with potentially minimal side effects, aiming to limit fat buildup damage.
