A disturbance of motor function caused by lesions or dysfunctions of the extrapyramidal motor system and may present as hyperkinetic-hypotonic or as akinetic-rigid disorder. Drug-induced movement disorders may occur in association with levodopa or dopamine agonist therapy or drugs with central dopamine receptor antagonist properties, anticholinergic drugs, some anticonvulsant drugs, and amphetamines. Divided into the 4 disorder complexes associated with disease of the basal ganglia. o Akathisia: subjective feelings of restlessness, objective signs of restlessness, or both. o Dyskinesia: (including tardive dyskinesia): involuntary choreoathetoid movements commonly involving orofacial region, fingers, and toes. Athetoid movements of head, neck, and hips may also occur. o Dystonia: brief or prolonged contractions of muscles resulting in abnormal movements or postures, including oculogyric crises, tongue protrusion, trismus, torticollis, laryngeal-pharyngeal dystonias, and dystonic postures of the limbs and trunk. o Parkinson\'s like events: triad of resting tremor, rigidity and bradykinesia that can appear identical to Idiopathic Parkinson\'s disease. Other Parkinson\'s-like features include bradyphrenia (slowed thinking), excessive salivation, drooling, shuffling gait, micrographia, hypophonia, and diminished postural reflexes.
