Question

Quizplus · Accepted Answer

Ashley's symptoms fit the pattern of Huntington disease, a genetic disorder that affects movement, cognition, and behavior. The fact that her father had similar symptoms before his early death supports the suspicion of a genetic disorder. Parkinson's disease and multiple sclerosis have different symptoms and do not typically have such a strong genetic component as Huntington disease. A brain tumor could cause some of the symptoms described, but it is less likely given the family history and the specific pattern of symptoms.
