Pseudochoreoathetosis

Pseudochoreoathetosis

Pseudochoreoathetosis is the name given to choreoathetoid type involuntary movements, including dystonic movements, which result from a loss or impairment of proprioception. These may be observed with lesions anywhere along the proprioceptive pathways, including parietal cortex, thalamus (may be associated with ataxic hemiparesis and hemihypoesthesia), spinal cord, dorsal root ganglia (neuronopathy), and mononeuropathy.
