Tardive Dyskinesia

Tardive Dyskinesia is a nervous system disorder that results in repetitive, involuntary body movements such as grimacing, lip-puckering or smacking, tongue protrusion, respiratory irregularity and difficulty breathing, rapid eye-blinking or involuntary movements of the limbs, torso and fingers. In some cases a patient's legs may be so heavily affected that walking becomes difficult or impossible. These movements have a slow or belated onset and frequently appear after long-term or high dosage use of antipsychotic medications and is often diagnosed as a mental disorder than as a neurological disorder.
