Need help playing a character with memory problems

well for one, depending on how long they known the other chars they would likely forget who they are, and not know them. possibly mistake them for potential enemies? view them with suspicion. 

unless they are childhood friends or long term friends. my nan had alzheimers and dementia, she seemed to forget all memories up to a certain point but yet had her youth memories which her brain seemed to back on and cycle back to.... kinda like when you have a pc issue, and you have to restore you pc back to its last restore point, but its last restore point was like ....50 years ago... you think you are that person 50 years ago in that time and still have those people you knew around back then, then you realise your old, your not that young person, this confuses you, you wonder were all the people you know have gone, and see a new set of people that are alien to you but claim to know you and be related, you perhaps may see familial similarity in them which confuses you more, then they tell you all your freinds you think are still current and in your time, are long dead, which then gives you back your grief as if you only just lost your closest friends all at once all over again like new.

she also had hallucinations for some reason, probably brain breakdown due to the dementia? but she used to hallucinate and start screaming in bed thinking there was snakes in her bed.

you forget every basic thing like how to go to the toilet and detecting whether you need the toilet, you pretty much sit slumped in a chair which is also commode vacant most of the time, drooling. every now and then laughing or screaming for no reason. you cant walk, perhaps you forgot how to walk or perhaps because you stayed bed ridden too long that your muscles dont work but maybe it could be a forgetting of how to walk or to use your muscles.

it doesnt matter if someone just brought you up to date with all the current things and the fact everyone you know has died, you forget, then have to be told again, and again, and again, you will be on a repeat of wondering were your mum is, when your mum has died 50 years ago, and being told that she has died long ago, getting upset and grief stricken about it, then losing the memory and then asking again, a constant cycle of forgetting, asking where someone is, remembering they are dead, getting upset, then forgetting, over and over again.

for rpg mechanics though.... this forgetting and cycling back to a older point can be done in a game mechanic way in that if your char is a level 20, when they slip into dementia they perhaps cycle back to being a level 4 or something.
