question: In the last year my dad has been diagnosed with a genetic brain disease called CCM type 3 and I have been diagnosed as well. But i do not necessarily have the same symptoms. Earlier this year they found a tumor on his brain stem and it has caused his social skills, reasoning skills to go downhill, and it has changed his personality. I am afraid that this will happen to me as well. If so I don t ever want to get married and put my spouse through what my mom goes through. What do i do?
