Description
An apraxia characterized by the affected limb having involuntary, autonomous, and purposeful behaviors that are perceived as being controlled by an external force. Often the affected limb interferes with the actions of the normal limb. Symptoms develop from lesions in the CORPUS CALLOSUM or medial frontal cortex caused by stroke, infarction, and neurodegenerative diseases (e.g., CREUTZFELDT-JAKOB SYNDROME, corticobasal degeneration).
