Alcohol and dementia: Heavy drinking closely related to early onset condition, study finds | Idaho Statesman
"Of the 57,000 cases of early-onset dementia, the researchers found that more than half (about 57 percent) were at least related to chronic heavy drinking, which is defined as drinking about four or five drinks a day for men and about three a day for women, according to the World Health Organization."
“The findings indicate that heavy drinking and alcohol use disorders are the most important risk factors for dementia, and especially important for those types of dementia which start before age 65, and which lead to premature deaths,” Dr. Jürgen Rehm, study co-author and director of the CAMH Institute for Mental Health Policy Research, said in a news release."
