the illness my grandmother and mother have is hereditary. but it does not skip a generation. if it misses me my children will never get it. it is an inbalance of the brain . it is where the cerebal part of the brain deteriates and causes you to loss your balance. and fall down all the time. you live like you are drunk.it causes you to have an inner ear problem. thanks sandy p.s. i dont know where the desease came from the adams or the hutchinson side of the family.
