HD involves three main symptom groups.
- Abnormal movements can include too much movement (chorea), uncoordinated movements (dystonia), and too little movement or the slowness of movement (bradykinesia).
- Cognitive impairments frequently include problems with organization, task sequencing, multitasking, memory recall, social judgments, impulse control, language expression, and the inability to suppress normal stimuli.
- Psychiatric symptoms include depression, impulsivity, apathy, obsessive behavior, unawareness, irritability, and in some cases mania, changes in sexuality, and psychosis.
When these symptoms occur, medical care and certain medications can be helpful. For more information on how to handle the symptoms of HD, read about treatments.
