Chorea is characterized by:

Chorea is characterized by:

• A. Slow, twisting, writhing movements
• B. Irregular, unpredictable movements that are brief
• C. Excessive muscle strength in the lower extremities
• D. Fluttering movements of the eyelids

Answer: (B)

Chorea is indeed characterized by irregular, unpredictable movements that are often brief and appear to be sudden. These involuntary movements can affect various body parts and are typically non-repetitive, making them distinct from other movement disorders. Chorea can manifest as a range of movements, such as quick jerks or fidgeting motions that can disrupt normal activities. In contrast, slow, twisting, writhing movements describe a different condition known as dystonia, which is characterized by sustained muscle contractions and abnormal postures. Excessive muscle strength in the lower extremities does not align with the definition of chorea, as the disorder involves involuntary movements rather than increased strength. Fluttering movements of the eyelids, also known as myokymia, are not indicative of chorea but relate to separate muscular disturbances that specifically affect the eyelids. Thus, the nature of chorea aligns perfectly with unpredictable, brief movements, highlighting the unique characteristics that make it identifiable.
