Does anybody have any experience with alzheimer's disease?

my dad has early on set dementia. I have read up a lot on it but unfortunately was too late for him.

You can ask for a blood test for b-vitamins. Quite often a high dose b-vit injection can help as those with dementia can be severely lacking.
If it came on suddenly it could have been accelerated by a stroke as this can cause dementia as it did with my nan.
This is a helpful association to get advice and help from - http://www.alzheimers.org.uk
and it has a facebook group too - http://www.facebook.com/alzheimerssocietyuk
It can be very distressing to watch a love one go through this, find a local group that you can go to where people can give you the support you need.
