New preclinical research in rats has identified a link between adolescent alcohol exposure and specific molecular changes in the brain that contribute to increased anxiety in adulthood. A large body of evidence demonstrates a strong relationship between alcohol and anxiety problems in humans. “These findings provide insight into the mechanisms through which alcohol-induced brain changes … Read more

NIH study of brain energy patterns provides new insights into alcohol effects

Image of brain scans

Assessing the patterns of energy use and neuronal activity simultaneously in the human brain improves our understanding of how alcohol affects the brain, according to new research by scientists at the National Institutes of Health. The new approach for characterizing brain energetic patterns could also be useful for studying other neuropsychiatric diseases. A report of … Read more

Lack of sleep may be linked to risk factor for Alzheimer’s disease

Illustration of beta-amyloid accumulation

Preliminary NIH study shows increased levels of beta-amyloid Losing just one night of sleep led to an immediate increase in beta-amyloid, a protein in the brain associated with Alzheimer’s disease, according to a small, new study by researchers at the National Institutes of Health. In Alzheimer’s disease, beta-amyloid proteins clump together to form amyloid plaques, … Read more
