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).
Senile chorea (SeC) is the descriptive term used to describe chorea with onset at age greater than 64 years with the lack of family history, dementia, or identifiable cause. As a myriad of conditions may account for chorea at this age, they need to be ruled out for the diagnosis of SeC to be made.
