Dr. Romina Mizrahi: Cannabis disrupts brain activity in young adults prone to psychosis: study

Published on: 2024-11-20

A new study led by Dr. Romina Mizrahi reveals that young adults at risk of psychosis exhibit reduced brain connectivity, a deficit further exacerbated by cannabis use.

The findings indicate that cannabis disrupts the brain’s natural process of synaptic pruning and refinement, essential for healthy brain development. Published in JAMA Psychiatry, the study links lower synaptic density to symptoms like social withdrawal and lack of motivation, which remain challenging to treat with current medications.

This research offers hope for therapies that specifically address these symptoms, aiming to enhance social functioning and overall quality of life. It also lays the foundation for early interventions to prevent the progression of psychosis.

« Not every cannabis user will develop psychosis, but for some, the risks are high. Our research helps clarify why.»
