Alzheimers of Picks and me

My mother started showing signs of dementia when she was in her mid 50's.  No one in Mom's family had these type of symptoms at a young age. In fact, most lived into their 80's and 90's and were still living alone.  Because of that I wasn't convinced she had Alzheimers.  A relative told me about Picks.  He said it was caused by stress or abuse.  My mother was verbally and emotionally abused by my father their entire marriage. I could understand closing her mind to get away from him.

I guess my questions are...
Is this a true statement regarding Picks?

Are Alzheimers or Picks inheirited?  (Sorry, I know that's spelled wrong)

I'm getting close to the age my mother was when she first started exhibiting symptoms and am scared to death.  Every time I misplace my keys or forget someones name I panic, thinking that I'm getting one disease or the other.

Can anyone help?  Mom passed away in February after suffering with this for over 20 years.  I need to know if I'm going to be imprisoned like Mom was.

Thanks!
