Tardive dyskinesia (TD) is a disorder that involves involuntary movements, most often affecting the tongue, lips, and face.
TD is caused by the use of dopamine receptor blocking drugs that are prescribed to treat certain psychiatric or gastrointestinal conditions. People with schizophrenia and other neuropsychiatric disorders are especially vulnerable to developing TD when exposed to neuroleptics, anticholinergics, toxins, and other agents. Neuroleptics block dopamine receptors in the brain that help brain cells to communicate.
What are the symptoms of tardive dyskinesia (TD)?
Symptoms of TD include:
Sticking tongue out
In some cases, the arms and/or legs may also be affected by involuntary rapid, jerking movements (chorea), or slow, writhing movements (athetosis).

Treatment for TD primarily consists of discontinuing the neuroleptic drug as soon as characteristic symptoms are identified in people taking the drugs, if medically appropriate.
