inherited degenerative neurologic disorder
- characterized by CHOREA
- typically progresses into mental deterioration> death
chorea
uncontrollable jerking movements
huntington disease onset
middle age
-often after theyve already had kids
huntington disease subjective findings
- difficulty w reasoning
- dysphagia
- disinhibition
huntington disease objective findings
- muscle rigidity
