[verse18]

Tardive dyskinesia is a neurological syndrome caused by the
long-term use of neuroleptic drugs. Neuroleptic drugs are
generally prescribed for psychiatric disorders, as well as for
some gastrointestinal and neurological disorders. Tardive
dyskinesia is characterized by repetitive, involuntary,
purposeless movements. Features of the disorder may include
grimacing, tongue protrusion, lip smacking, puckering and
pursing, and rapid eye blinking. Rapid movements of the arms,
legs, and trunk may also occur. Involuntary movements of the
fingers may appear as though the patient is playing an
invisible guitar or piano.
