Drinking and dementia

Hi all,

So my mum is in her early 60’s, and is a pretty heavy drinker. Like 3 bottles of wine and maybe 10-15 pints a week.

Does drinking this amount mean she will be at increase risk down the line? I can’t really find straight answers on line, does anyone have any knowledge/experience on this? Sorry if this is the wrong place to ask, I know it’s quite a general question!
