Alcohol exhibits a split personality when it comes to the influence it has on the development of dementia and similar conditions, such as Alzheimer's. Low-to-moderate intake apparently protects the brain against these disorders, while high intake accelerates their development.

These are the conclusions of a new scientific study, which was conducted by experts at the Boston University Medical Center. Details of the work appear in the latest issue of the esteemed journal Psychiatry Investigation.

Excessive drinking is especially bad for seniors, who are exposed to a higher risk of developing cognitive dysfunctions and memory loss. Scientists do not yet know if low alcohol intake protects this age group against this array of conditions, so they plan to investigate this in detail.

“Current biomedical data supports the concept that regular, moderate intake of ethanol is not simply less dangerous for cognitive function, but is positively protective. This is the same conclusion reached by epidemiologic studies,” the team writes in its journal entry, according to PsychCentral.
