Tardive dyskinesia: are first signs reversible?

F Quitkin, A Rifkin, L Gochfeld

    The American Journal of Psychiatry
    |January 1, 1977
    PubMed
    Summary

    Tardive dyskinesia, a side effect of antipsychotics, may be reversible. Early symptom duration, not age, appears key to recovery when antipsychotic medication is stopped.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Pharmacology

    Background:

    • Tardive dyskinesia (TD) is a concerning, potentially irreversible side effect of antipsychotic medications.
    • Increasing prevalence of TD highlights the need for understanding its clinical course and reversibility.
    • Existing knowledge regarding TD's prognosis remains incomplete, causing clinical uncertainty.

    Purpose of the Study:

    • To investigate the course and reversibility of tardive dyskinesia.
    • To identify factors influencing the persistence or resolution of TD symptoms.
    • To clarify the relationship between symptom duration, age of onset, and TD reversibility.

    Main Methods:

    • Longitudinal observation of 12 psychiatric patients diagnosed with tardive dyskinesia.
    • Monitoring patients from the initial presentation of TD symptoms.
    • Assessment of symptom persistence following discontinuation of antipsychotic medication.

    Main Results:

    • First-episode TD symptoms showed a low rate of persistence after antipsychotic discontinuation.
    • The duration of symptoms before drug cessation was a significant factor in reversibility.
    • Age at onset did not appear to be the primary determinant of TD reversibility.

    Conclusions:

    • Early intervention and discontinuation of antipsychotic medication may improve the chances of TD symptom reversal.
    • The duration of untreated TD symptoms is a critical factor in predicting recovery.
    • Further research is warranted to fully elucidate the mechanisms and management of tardive dyskinesia.
