Drinking and vascular dementia

It is easy to point the finger at Dave and think he has vascular dementia from too much drinking.  His German heritage made it normal to consume a lot of beer.  Was it the beer or the hard alcohol that created plaque in his veins?  Was it beer that made his father have a cerebral stroke... again, vascular issues? A depressing thought.  This could have been prevented.
   It was a wake up call for my kids when they witnessed their dad in a coma, recovering from an operation, complicated by withdrawal. Again the alcohol.  It is in the genes.  Hence we all drink too much.  I know I do.
   I could go on and on about this depressing topic but it is easier to say, it is what it is, sweep it under the table and forget it.  Except maybe a word to the wise is sufficient, as my mother used to say.
