Acetazolamide relieves concurrent episodic movement disorders encountered in Southern states.

Patients with episodic or paroxysmal movements or postures often are thought to have hysteric or psychosomatic illnesses. Kinesigenic (movement-induced) posturing similarly is usually misinterpreted. This case is notable because of the presence of symptoms of two distinct diseases with similar symptoms and changes from one dystonic posture to another during three different durations of attack. The condition improved with acetazolamide therapy. The effect of acetazolamide on sodium and potassium ionophores is discussed because of new genetic information about these illnesses.
