Not sure of question
I'm a little uncertain about some aspects of the question--you said when you were "little your dad had c-m-t".
Not sure if you saying he no longer has it, or he is no longer with you. It is not something that goes away, and if that has seemed to be the case, re-evaluation is in order. There are a number of different types, and seeing a neurologist familiar with the genetics of it may be useful.
