Apraxia – Joseph H. Friedman, MD
This patient has a rare neurodegenerative disorder, corticobasal syndrome. It has that name because it causes parkinsonism (a syndrome with slowed movements, stooped posture and shuffling gait), a basal ganglia disorder, and aphasia or apraxia, both caused by dysfunction in the cerebral cortex.

Apraxia is an inability to voluntarily perform a maneuver that the person is physically able to perform. In this case, she has difficulty continuing to perform rapid alternating hand movements on the left after doing a few. More severe was her inability to slide her left foot up and down her right shin. Apraxia is due to dysfunction in the parietal lobe and is seen in a number of disorders, most commonly stroke. It is rarely so severe as in this case.
