I also have Fahr's. I'm 33 and have been experiencing symptoms for about 3 years. (Slight tremors in the hands, muscle stiffness, difficulty walking, twitches, involuntary curling of the toes, depression, some very minor short-term memory loss, dizziness, and feelings of numbness in the head)

So far it is progressing relatively slow. I was wondering how long before I start experiencing seizures and/or dementia, or does it vary from person to person?
