Is chorea and Huntington’s disease the same?
Chorea, which is sometimes a symptom of Huntington’s disease, but not deadly, is one of several known involuntary movements, which also include more common ones such as tremor and tics. To the untrained eye, it can be challenging to identify chorea, because its appearance varies from one individual to another.
What is the best treatment for chorea?

What is the difference between chorea and tics?
Tics are stereotyped, repetitive movements that tend to change in type and anatomical location over long periods of time. The primary difference between tics and chorea is that tics are stereotyped, whereas choreatic movements tend to vary in location from movement to movement.

What are the causes and treatment of chorea?
Metabolic and endocrine-related choreas are treated according to the cause(s) of symptoms. Chorea is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias, which are caused by overactivity of the neurotransmitter dopamine in the areas of the brain that control movement.
Is the chorea movement disorder a disease or symptom?
