Neuroleptic Induced Tardive
Dyskinesia
|
A medication-induced movement disorder, this symptom
associated with neuroleptic drugs used
in the treatment of mental disorders is characterized by
progressive involuntary movements, usually beginning in the voluntary muscles of the head.
They may progress to involve the limbs and trunk. The movements may be described as
choreiform, athetoid, or rhythmic. They may last indefinitely, but may appear to resolve
with increased dose of the neuroleptic.
