Involuntary movements that are irregular and writhing, creating an appearance of restlessness. Choreoathetosis can involve the face, neck, arms, legs, trunk, and respiratory muscles. Movements range from subtle to wild and ballistic. They can be a side effect of the drug levodopa (used to treat Parkinson disease) and an effect of Huntington disease.
A type of athetosis frequently seen in cerebral palsy, marked by extreme range of motion, jerky involuntary movements that are more proximal than distal, and muscle tone fluctuating from hypotonia to hypertonia.
The described condition entails involuntary movements affecting the limbs, face, and trunk. This disorder manifests as a combination of rapid and jerky motions akin to chorea, along with the slower and continuous writhing movements characteristic of athetosis.
Choreoathetosis can manifest in children diagnosed with cerebral palsy, and it may also arise as an adverse reaction to specific medications.
