  Tardive dyskinesia - Wikipedia, the free encyclopedia
Tardive dyskinesia is a serious neurological disorder caused by the long-term and/or high-dose use of dopamine antagonists, usually antipsychotics and among them especially the typical antipsychotics.
The cause of tardive dyskinesia appears to be related to damage — due to the use of antipsychotic medications — to the system that uses and processes the neurotransmitter dopamine.
Tardive dyskinesia most commonly occurs in patients with schizophrenia, bipolar disorder, or other psychiatric conditions who are given antipsychotic medication, but it can occur in other patients who are treated with these drugs.

 Dyskinesia - Wikipedia, the free encyclopedia
Dyskinesia is sometimes caused by long-term use of anti-psychotic drugs or other dopamine antagonists like the antiemetic metoclopramide.
The effect of these drugs can be tardive, meaning the dyskinesia continues or appears even after the drugs are no longer taken (see Tardive dyskinesia).
Dyskinesias most commonly occur at the time of peak levodopa plasma concentrations and are thus referred to as peak-dose dyskinesias.

 Parkinson’s Disease and Movement Disorder Center - University of Kansas Medical Center
Tardive (meaning "late onset") dyskinesia (meaning "abnormal involuntary movement") is a term used to describe a syndrome occurring as a result of treatment with medications that block the receptors for the neurotransmitter dopamine in the brain.
Tardive dyskinesia was first described in the 1950s in patients treated with antipsychotic medications.
Tardive dystonia clinically appears identical to idiopathic or primary dystonia (meaning "of unknown cause") but is classified as a secondary dystonia since it is the result of a known agent.

 Drug-Induced Tardive Movement Disorders
The mechanism of tardive parkinsonism appears to be the drug-induced opposition or blockade of striatal dopamine receptors.
Once tardive dyskinesia presents, a gradual reduction of the neuroleptic should be attempted in hopes of a spontaneous remission.
Other drug-induced movement disorders including tardive dyskinesia, akathisia (a subjective sensation of restlessness) or myoclonus may accompany tardive dystonia, and have led many researchers to classify tardive dystonia as a variant of tardive dyskinesia, Unlike tardive dyskinesia, tardive dystonia is seen in children as well as adults.

Tardive dystonia may appear at any time in the course of treatment with DRAs and up to years afterward, while acute dystonia may occur within a few days of exposure.
Backward arching of the trunk is primarily seen in acute dystonia; spasmodic torticollis, retrocollis, and internal rotation of the arms, elbow extension, and wrist flexion are characteristic of tardive dystonia.
Tardive akathisia usually exists concurrently with tardive dystonia or tardive dyskinesia but may also occur in isolation.

 Neuroleptics, psychiatric drug hazards and tardive dyskinesia by Peter R. Breggin, MD
In long-term studies, the prevalence of tardive dyskinesia often exceeds 50 per cent of all treated patients and is probably much higher.
Tardive akathisia involves painful feelings of inner tension and anxiety and a compulsive drive to move the body.
The basal ganglia, which are afflicted in tardive dyskinesia, are richly interconnected with the higher centres of the brain, so that their dysfunction almost inevitably leads to disturbances in cognitive processes (for the functional neuroanatomy, see Alheid et al., 1990).

 Risperdal Side Effects: Tardive Dyskinesia
The phrase comes from tardive, which means "late" and dyskinesia which means "abnormal movement." The cause of tardive dyskinesia appears to be related to damage---due to the use of antipsychotic medications---to the system that uses and processes the neurotransmitter dopamine.
There is no standard treatment for tardive dyskinesia, which in many cases appears to be irreversible and may even get worse if use of the chemical agent(s) that caused it is stopped.
Even so, when tardive dyskinesia develops, the first step is generally to stop or reduce the use of the neuroleptic drug in order to prevent further damage and worsening of the symptoms.

 eMedicine - Dystonia, Tardive : Article by Perla Periut, MD   (Site not responding. Last check: 2007-11-06)
In 1988, Burke and Kang suggested that tardive dystonia is distinguished from the classic oral-buccal-lingual choreic form of tardive dyskinesia not only by the dystonic nature of the involuntary movements but also by the frequency with which it causes significant neurologic disability.
The current model used to explain the mechanism underlying tardive dyskinesia is the supersensitivity of the postsynaptic dopamine striatal receptors resulting from the long-term administration of dopamine receptor–blocking agents.
Tardive akathisia, characterized by subjective and motor restlessness, is present in 31% of patients with tardive dystonia.

 WE MOVE - Tardive Dyskinesia - Definition
In general, tardive dyskinesia (TD) refers to a wide variety of involuntary, repetitive, persistent, stereotypic movements caused by the use of drugs that block dopamine receptors.
Dyskinesia is from the Greek words, dys and kinEsis, meaning difficulty of movement.
Tardive comes from the French word (tardif) for tardy or late, meaning that the dyskinesias appear late in the course of therapy with a drug that blocks dopamine receptors (DRAs).

Tardive dyskinesia is a syndrome involving dysfunctional, involuntary movements associated with long-term, chronic use of neuroleptic medications, such as Haldol, Prolixin, and Thorazine.
Common tardive dyskinesia movements include, but are not limited to: facial tics, grimacing, eye blinking, lip smacking, tongue thrusting, moving one's head back or to the side, foot tapping, ankle movements, shuffled gait, and head nodding.
Tardive dyskinesia movements may be confused with stereotypy because of the repetitive nature of both behaviors.

 Drug-induced and Tardive Movement Disorders
Involuntary movements, including tremor, chorea, athetosis, dyskinesias, dystonia, myoclonus, tics, ballismus and akathisia, may be symptoms of primary neurologic disease or occur secondary to pharmacotherapy (Table 1).
Drug-induced and tardive parkinsonism resemble idiopathic parkinsonism, and are therefore characterized by tremor, rigidity and most commonly an extreme paucity of movement called akinesia.
Neuroleptic malignant syndrome is the least common of the extrapyramidal adverse effects of neuroleptic drugs, but the most dangerous.[2] Idiosyncratic reactions including fever, severe rigidity, tremor, autonomic instability and obtundation lead to pulmonary embolism, myocardial infarction and disseminated intravascular coagulation.
