My DH has vascular/Alzheimers dementia. He has since the age of 45 been a moderate drinker. However, now, with mild/moderate dementia it seems to me that after not very much to drink he does not cope well mentally, and starts talking rubbish - and being confrontational (not physically aggressive) - which he admits himself later. Is it likely that having the dementia increases the effects of alcohol - the only reports I can find are on whether alcohol consumption can be involved are in getting dementia in the first place.
