Introduction:Long-acting depot antipsychotic medication is associated with extrapyramidal side effects (EPS). This may reduce adherence to medication, and precipitate relapse (1). Clearly, EPS is a major drawback and early detection is essential. However, in an earlier review of patients’ medical notes, we identified only one patient with an examination that recorded the presence of EPS. Despite the fact that a number of rating scales are available. We proposed that the application of these rating scales, would allow us to improve the assessment of EPS.Method:All patients prescribed a depot antipsychotic or long-acting risperidone injection, were identified. the Barnes Akathisia Scale (2) was chosen to rate akathisia, a modified Simpson-Angus scale (3) was chosen to rate parkinsonism and the Abnormal Involuntary Movement Scale (4) was chosen to rate tardive dyskinesia.Results:A total of 43 patients were evaluated. 23 (53%) patients showed drug induced EPS. the total number of positive cases of akathisia was 12 (28%), and 10 (23%) patients were found to have tardive dyskinesia. 13 (30%) patients were found to have drug induced parkinsonism.Conclusions:Our screening programme has identified high rates of previously undiscovered drug induced EPS.

Neuroleptic Therapy

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 Dystonia

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.

Prevention Model

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.

Extrapyramidal Disorders

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.

Background Antipsychotic agents are the basis for the pharmacological management of acute and chronic schizophrenia, bipolar disorders, mood disorders with psychotic feature, and other psychotic disorders. Antipsychotic medication use is frequently associated with unfavorable adverse effects such as extrapyramidal side effects (EPSEs). Hence, this systematic review and meta-analysis was aimed to determine the magnitude of antipsychotic-induced EPSEs. Method A literature search was conducted using legitimate databases, indexing services, and directories including PubMed/MEDLINE (Ovid®), EMBASE (Ovid®), google scholar and WorldCat to retrieve studies. Following screening and eligibility, the relevant data were extracted from the included studies using an Excel sheet and exported to STATA 15.0 software for analyses. The Random effects pooling model was used to analyze outcome measures at a 95% confidence interval. Besides, publication bias analysis was conducted. The protocol has been registered on PROSPERO with ID: CRD42020175168. Result In total, 15 original articles were included for the systematic review and meta-analysis. The pooled prevalence of antipsychotic-induced EPSEs among patient taking antipsychotic medications was 37% (95% CI: 18–55%, before sensitivity) and 31% (95% CI: 19–44%, after sensitivity). The prevalence of antipsychotic-induced parkinsonism, akathisia, and tardive dyskinesia was 20% (95% CI: 11–28%), 11% (95% CI: 6–17%), and 7% (95% CI: 4–9%), respectively. To confirm a small-study effect, Egger’s regression test accompanied by funnel plot asymmetry demonstrated that there was a sort of publication bias in studies reporting akathisia and tardive dyskinesia. Conclusion The prevalence of antipsychotic-induced EPSEs was considerably high. One in five and more than one in ten patients experienced parkinsonism and akathisia, respectively. Appropriate prevention and early management of these effects can enhance the net benefits of antipsychotics.

Extrapyramidal Syndromes

One of the main advantages of clozapine is that it rarely produces extrapyramidal syndromes and tardive dyskinesia. This advantage is linked to the atypical biochemical profile of clozapine, especially its combined and low blockade of D1 and D2 receptors. The level of D2 receptor blockade is too low to induce extrapyramidal side-effects, and D1 antagonists have a lower extrapyramidal side-effect potential than traditional D2 neuroleptics, especially with respect to dystonia. The combined and balanced D1/D2 receptor blockade may prevent the development of a dysbalance between D1/D2 receptor function (in favour of D1) which otherwise might lead to tardive dyskinesia.

BackgroundThere are claims that second-generation antipsychotics produce fewer extrapyramidal side-effects (EPS) compared with first-generation drugs.AimsTo compare the incidence of treatment-emergent EPS between second-generation antipsychotics and perphenazine in people with schizophrenia.MethodIncidence analyses integrated data from standardised rating scales and documented use of concomitant medication or treatment discontinuation for EPS events. Mixed model analyses of change in rating scales from baseline were also conducted.ResultsThere were no significant differences in incidence or change in rating scales for parkinsonism, dystonia, akathisia or tardive dyskinesia when comparing second-generation antipsychotics with perphenazine or comparing between second-generation antipsychotics. Secondary analyses revealed greater rates of concomitant antiparkinsonism medication among individuals on risperidone and lower rates among individuals on quetiapine, and lower rates of discontinuation because of parkinsonism among people on quetiapine and ziprasidone. There was a trend for a greater likelihood of concomitant medication for akathisia among individuals on risperidone and perphenazine.ConclusionsThe incidence of treatment-emergent EPS and change in EPS ratings indicated that there are no significant differences between second-generation antipsychotics and perphenazine or between second-generation antipsychotics in people with schizophrenia.

Bipolar Illness

The drug class of dopamine blockers includes agents called antipsychotics. It consists of dopamine blockers, often with serotonin blockade. Dopamine blockers are agents used to treat psychotic symptoms such as delusions and hallucinations. These medications have been developed mostly for use in schizophrenia, but they always have been found to be effective in acute mania as well. For the latter reason, they have been used in bipolar illness as well. Several of these agents have been proven effective in the depressive phase of bipolar illness, not just the manic phase. Also, some of them have been shown to be effective in the depressive phase of unipolar mood illness. The clinical pharmacology of specific agents within each class of dopamine blockers, including efficacy and side effects, is explored. Specific phenomena surveyed include metabolic syndrome, weight gain, extrapyramidal side effects, Parkinsonism, akathisia, and tardive dyskinesia.
