Dehydroepiandrosterone (DHEA) as an add-on treatment for schizophrenia showed mixed results. While some symptom improvements were noted, overall findings were inconclusive, suggesting DHEA remains experimental.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Pharmacology

Background:

  • Sex hormones, including estrogens and testosterone derivatives, are being investigated for treating persistent schizophrenia symptoms.
  • Dehydroepiandrosterone (DHEA) is a hormone precursor with potential therapeutic applications.

Purpose of the Study:

  • To review the efficacy of dehydroepiandrosterone (DHEA)/testosterone as adjunctive therapy to standard antipsychotic medications in schizophrenia patients.
  • To synthesize findings from randomized controlled trials examining DHEA/testosterone augmentation in schizophrenia treatment.

Main Methods:

  • A systematic search of the Cochrane Schizophrenia Group Trials Register was conducted.
  • Clinical randomized trials comparing DHEA/testosterone plus antipsychotics versus antipsychotics alone were included.

  • Data extraction and analysis followed Cochrane guidelines, using fixed-effects models for dichotomous and continuous outcomes.

    • Main Results:

    • Three small, short trials (n=126) were analyzed.
    • Most outcomes, including total and positive PANSS scores, were not significantly different between groups.
    • Some positive findings for negative symptoms (SANS scale) and extrapyramidal symptoms (St Hans Rating Scale) were observed, but results were often equivocal or contradictory.
    • Participant dropout rates were similar between groups, and quality of life appeared unaffected.

    Conclusions:

    • The current evidence is inconclusive, with non-significant or contradictory findings for most outcomes.
    • Adjunctive dehydroepiandrosterone (DHEA) should be considered an experimental treatment for schizophrenia.
    • Further high-quality research is needed to clarify the role of DHEA in schizophrenia management.
