By Sandee LaMotte, CNN(CNN) — Drinking any amount of alcohol increases your risk of dementia later in life, according to a new study that challenges prior research findings. However, for people with less genetic risk for Alzheimer’s it often depends on “when” and “how” people drink, Isaacson added. Higher genetic risk was associated with an increased risk of dementia, with a linear increase in dementia risk the higher the alcohol consumption, according to the study. “There is a 15% higher dementia risk for 3 drinks per week compared to 1 drink per week across life,” Topiwala said. In addition, a doubling in the genetic risk of alcohol dependency was associated with a 16% increase in dementia risk, according to the study.
