At 30yo? I'm guessing brain tumor :|
I don't think so. If you have these there's no cure for it. He was able to travel back so maybe not.
Even some young children get dementia or alzheimer's
I don’t think it’s either of those cause those are long term illnesses that only progress and get worse over time and since he’s 73 and even remembering his youthful years i can see it being a brain tumor
It most likely is a brain tumor because when you have those you get worse he probably might had a surgery went in a coma and woke up to his wife being dead
dementia or alzheimer's?? noooo
