What is chorea? Chorea refers to involuntary movements characterized by their random, brief, and non-rhythmic character. They are often described as seeming to âflowâ from one body part to another unpredictably, though they can also be confined to a single area of the body (such as the mouth area or hands).
Choreoathetosis is essentially an intermediate form (ie, a bit more rapid than the usual athetosis, slower than the usual chorea, or a mingling of chorea and athetosis within the same patient at different times or in different limbs).
