However, brain imaging studies have shown that, in older people, even moderate alcohol consumption is associated with reduced brain total volume, increased ventricle size, and reduced grey matter in the frontal and parietal lobes.

Heavy drinking is known to be associated with Korsakoff’s syndrome, alcoholic dementia and widespread brain atrophy. Light drinking has been associated with an increase in oropharyngeal, oesophageal and breast cancer, but was previously thought to be protective against cognitive decline.
