Adolescent Excessive Drinking Impairs Astrocyte Function, Increases Anxiety Risk, Study Finds

Recent neuroscience research indicates that excessive alcohol consumption during adolescence can leave permanent damage to brain health that persists into adulthood. The study found that even after quitting alcohol, the structure and function of astrocytes—cells that support neuronal communication—remain impaired, which can trigger abnormal fear responses and anxiety disorders. The research was conducted by the School of Medicine at Marshall University in the United States and has been published in the peer‑reviewed journal Molecular Psychiatry. The findings highlight the critical role of astrocytes, often described as the brain's "guardians," in maintaining neural stability and suggest that early‑life drinking may have long‑term psychiatric consequences.
