Characteristics of tardive dyskinesia
What is the epidemiological characteristics of tardive dyskinesia symptoms?
Tardive dyskinesia presents clinically as stereotypical involuntary movements of the tongue, neck and facial muscles, truncal musculature, and limbs. Buccolingual movements including masticatory muscles are characterized by lip-smacking, tongue protrusion, perioral movements, chewing movements, or a puffing of cheeks.

How do you test for tardive dyskinesia?
The trunk, legs and mouth are again observed for signs of TD. The patient then walks a few paces, while his or her gait and hands are observed by the rater twice. The total score on the AIMS test is not reported to the patient. A rating of 2 or higher on the AIMS scale, however, is evidence of tardive dyskinesia.
What is the difference between dystonia and tardive dyskinesia?
Tardive dyskinesia causes involuntary movements most commonly in areas of the face, eyes, and mouth. Dystonia, on the other hand, leads to involuntary muscular contractions that can affect the head, face, and neck.
How long does tardive dyskinesia take to develop?
The symptoms of TD usually first appear after 1–2 years of continuous exposure to a DRBA and almost never before 3 months. Severity of TD ranges from mild involuntary movements often unnoticed by a patient to a disabling condition.
What is the Rabbit Syndrome?
Rabbit syndrome is an antipsychotic-induced rhythmic motion of the mouth/lips, resembling the chewing movements of a rabbit. The movement consists of a vertical-only motion, at about 5Hz, with no involvement of the tongue.
Does tardive dyskinesia start suddenly?
Tardive dyskinesia symptoms usually come on gradually. They may appear while taking an antipsychotic medication, but they can also show up months or even years after stopping the drug. A person should consult a doctor as soon as symptoms appear to help treat it in its early stages.
How long does tardive dyskinesia take to develop?
The symptoms of TD usually first appear after 1–2 years of continuous exposure to a DRBA and almost never before 3 months. Severity of TD ranges from mild involuntary movements often unnoticed by a patient to a disabling condition.
Should I go to the hospital for tardive dyskinesia?
If you have effects that seem to be getting worse, such as constant or worsening involuntary movements, be sure to get prompt medical attention.
Can TD go away on its own?

What does mild tardive dyskinesia look like?

What is an example of tardive dyskinesia?

What is the most common involuntary movement disorder?
“Essential” Tremor (ET) (Kinetic Tremor / Familial Tremor)
Most common involuntary movement disorder, typified by a rapid postural tremor most often of the upper extremities. Progressive, may appear at anytime of life but most commonly >70 years.
What’s the difference between tardive dyskinesia and dystonia?
Tardive dyskinesia is characterized by truncal, appendicular, or orobuccolingual choreiform movements; whereas tardive dystonia manifests as stereotyped twisting and turning muscle spasms. Tardive dyskinesia also tends to have a later age of onset than tardive dystonia.
