Alcohol-induced loss of consciousness is a long-term risk factor for dementia


  • Losing consciousness due to alcohol consumption doubles the risk of subsequent dementia regardless of overall alcohol consumption.

Why this matters

    The association between alcohol consumption and increased dementia risk is usually related to overall consumption; this is the first study to demonstrate that alcohol-induced loss of consciousness further increases the risk. This suggests that the drinking pattern may be even more significant than the overall weekly quantity consumed; the findings further our knowledge about the consequences of alcohol misuse on the brain.
