In the October issue of the Archives of Neurology Carol Ann Paul, of Wellesley College, and colleagues reports that alcohol makes our brains shrink.
Even moderate intake such as a small glass of wine over dinner every night has a significant effect.
The positive effect that low to moderate alcohol intake has on our blood flow only helps our heart not our brain. The study also showed that the negative effect is more serious for women.
Since declines in brain volume and increases in white matter lesions are associated with memory loss and worsening dementia, the effects of alcohol likely have some functional impact over time, says Carol Ann Paul.
