Tardive dyskinesia controlled by anticholinergic agents.

L M Monteiro

    Clinical Neuropharmacology
    |January 1, 1985
    PubMed
    Summary

    Tardive dyskinesia emerged in a teenage boy after stopping pimozide and thioridazine. Anticholinergic drugs resolved symptoms, while dopamine blockers worsened them, indicating a specific treatment approach for this condition.

    Area of Science:

    • Neuroscience
    • Pharmacology
    • Movement Disorders

    Background:

    • Tardive dyskinesia (TD) is a potential side effect of antipsychotic medications.
    • Understanding the specific mechanisms and effective treatments for TD is crucial for patient management.

    Observation:

    • A 17-year-old male developed choreodyskinetic movements affecting limbs and trunk after discontinuing pimozide and thioridazine.
    • The patient's symptoms showed a clear response to anticholinergic therapy and a negative reaction to dopaminergic agents.

    Findings:

    • Anticholinergic drugs, specifically benztropine mesylate (Cogentin), effectively treated the tardive dyskinesia.
    • Dopaminergic receptor blockers exacerbated the choreodyskinetic movements, highlighting the role of dopamine in the observed symptoms.

    Implications:

    • This case suggests a potential therapeutic strategy for drug-induced tardive dyskinesia involving anticholinergic agents.
    • Further research into the differential response to dopaminergic and anticholinergic agents in TD is warranted.
