"Drinking any quantity of alcohol could increase the risk of developing dementia, new research has shown. The study, led by researchers at the University of Oxford, Yale University and the University of Cambridge, analysed data from more than 559,000 people in the UK Biobank and the US Million Veteran Programme. Over the follow-up period, 14,540 participants developed dementia. The results of the observational data were striking."
"Heavy drinkers, defined as consuming 40 or more drinks a week, as well as non-drinkers, had a 41 per cent higher risk of developing dementia compared with light drinkers, who had fewer than seven drinks a week. For those who were alcohol dependent, the risk rose to 51 per cent. But the researchers also carried out genetic analysis, using genome-wide association studies (GWAS) of 2.4 million people to untangle correlation from causation."
Analysis of over 559,000 participants in the UK Biobank and the US Million Veteran Programme found 14,540 dementia cases during follow-up. Observational results showed heavy drinkers (40+ drinks/week) and non-drinkers had a 41% higher dementia risk than light drinkers (<7 drinks/week), while alcohol dependence raised risk to 51%. Researchers performed genetic analysis using GWAS data from 2.4 million people to distinguish correlation from causation. Three alcohol measures were assessed: self-reported weekly drinks, risky drinking and alcohol dependency. Findings indicate alcohol consumption at various levels links to elevated dementia risk.
