Rapamycin Temporarily Alleviates Autism-Like Behaviors in Adult Mice

A study in Nature Communications reported that a single dose of rapamycin temporarily improved autism-like brain and behavioral symptoms in adult mice. This research suggests that adult brain circuits may possess more adaptability than previously understood, even when underlying physical brain differences persist. However, researchers cautioned that rapamycin is not a viable human treatment due to its temporary effects and potential toxicity with repeated use.
