What treatment is there for alcohol brain damage?

My dad was an alcohol for about his whole life. He just quit a year ago and has not drank since. He has been fainting about twice or three times now in maybe the past year and a half. I am wondering how much brain damage he could have and what treatment is there for him. I know he will need an MRI. but i heard there were vitamins he needs to take to help repair some damage.

He will not go into the doc. He hasn't been for about 20 years
