Dyskinesias are involuntary movements usually of the face and tongue and sometimes of the limbs and trunk. Tardive (delayed) dyskinesia occurs in patients who have been taking an antipsychotic (neuroleptic) drug or, rarely, another central dopamine-receptor-blocking drug such as metoclopramide. It generally occurs only in those treated for longer than a year, although much shorter exposures have been implicated with the antipsychotics. A similar dyskinesia occurred in schizophrenic patients before antipsychotic drugs were introduced, and can occur in healthy untreated elderly people; risk factors include old age, brain damage1 and the schizophrenic disease process.2 Nevertheless, in most patients on an antipsychotic drug (whether psychotic or not), tardive dyskinesia is an unwanted effect of the drug. It occurs in 5–40% of patients on long-term antipsychotic medication.3–5 we discuss here advances in the management of this difficult condition since our last review.6

BackgroundIn recent years there has been a shift to ‘community care’ and the introduction of several ‘atypical’ antipsychotic drugs. We report the impact of these changes.MethodIn Nithsdale, Dumfries and Galloway, Scotland, the population of patients with schizophrenia was identified in 1996. This census replicated a study carried out in 1981. The population with schizophrenia were compared on clinical and social variables. The whereabouts in 1996 of the 1981 population was determined.ResultsIn comparison with the 1981 population, more patients in 1996 had positive, negative and non-schizophrenic symptoms. More showed tardive dyskinesia. Social adjustment had not changed. They had spent less time in hospital; fewer (13%) were living with their parents; and fewer (8%) were employed. By 1996, 35% of the 1981 cohort had died (standardised mortality rate male – 154, female – 162).ConclusionsThe mental health of a community of people with schizophrenia living in a rural area in 1996 was poorer than in 1981.

Antipsychotic drugs, such as the phenothiazines (chlorpromazine, fluphenazine, thioridazine), butyrophenones (haloperiodol), and diphenylbutylpiperidines (pimozide) are used in children and adolescents to treat a variety of clinical entities including psychoses, tics, behavior disorders, and movement problems. Because virtually all of these drugs have a potential to affect body movements and posture, they have also been termed neuroleptics.1 Most physicians are aware of the more common acute extrapyramidal side effects of these drugs, such as oculogyria, pseudoparkinsonism, dystonia, and restlessness (akathisia). Despite the widespread use of neuroleptics, however, little is known about the long-term neurologic consequences of such treatment. Of particular concern, based originally on data in adults, is the risk of severe and persistent tardive dyskinesia developing in persons receiving neuroleptic therapy.

Tardive syndromes are drug-induced hyperkinetic movement disorders that occur as a consequence of dopamine D2 receptor antagonism/blockade. There are several types, including classical tardive dyskinesia, tardive dystonia, tardive tics, tardive myoclonus, and tardive tremor, and it is important to the management of these disorders that the type of movement disorder induced is identified. Tardive syndromes can occur with all antipsychotic drugs, including so-called atypical drugs. Patients taking these drugs should be evaluated frequently for side effects. Evaluating the nature of the movement (i.e., chorea or dystonia) is important because treatment options can differ according to the type of dyskinesia present.

While the rate of tardive dyskinesia (TD) and other extrapyramidal side effects (EPSE) is lower with second generation antipsychotic medications compared to first generation antipsychotic medications, these side effects remain of clinical concern. This paper reviews the basis for the continued concern and the importance of secondary prevention, or early detection, within the primary-secondary-tertiary prevention model. The importance of standardized assessment instruments, education, and training is reviewed. Given the widespread use of antipsychotic drugs, the fact that antipsychotic drugs are the standard of care for several psychiatric conditions (with little indication that the magic bullet is on the immediate horizon to replace current antipsychotic drugs) applied monitoring and the early detection of TD and EPSE takes on added importance.

SummaryHyperkinetic movement disorders may occur as side effects of antipsychotic drugs; and a hyperdopaminergic state induced by the neuroleptic compounds is thought to be a cause of extrapyramidal disorders such as tardive dyskinesia. We have observed two cases of the dyskinetic syndrome in patients receiving tricyclic antidepressants (TCA). Because the TCA are known to have little effect on striatal dopamine but do share with the neuroleptics potent anticholinergic activity, these cases appear to support the hypothesis that the drug-induced hyperkinetic disorders are related to a diminution of CNS acetylcholine activity as well as to an increase in dopamine activity.
