Alcohol drives opposite brain circuit changes in amyloid and tau Alzheimer's models

Article excerpt

Alcohol use has been associated with an increased risk of cognitive decline and dementia. But new research from Texas A&M University's Naresh K. Vashisht College of Medicine at Texas A&M Health suggests the relationship between alcohol and Alzheimer's disease is more complicated than previously thought. Instead of affecting all Alzheimer's-related brain changes in the same way, alcohol interacted differently with amyloid-beta-related and tau-related pathology in animal models, two key pathological processes involved in Alzheimer's disease.
