Tardive dyskinesia (TD) is a disorder that results in involuntary, repetitive body
movements. This may include grimacing, sticking out the tongue, or smacking the lips.Additionally there may be rapid jerking movements or slow writhing movements. In about 20% of people, decreased functioning results.

Tardive dyskinesia occurs in some people as a result of long-term use of neuroleptic medications (antipsychotics, metoclopramide). These medications are usually used for mental illness, but may also be given for gastrointestinal or neurological problems. The condition typically develops only after months to years of use. The diagnosis is based on the symptoms after ruling out other potential causes.
