    Psychological tests and visual evoked potentials effectively track depression treatment progress. However, the TRH test and MHPG dosage offered limited insights into patient outcomes.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Psychology

    Context:

    • Major depressive disorder (MDD) diagnosis and treatment monitoring present ongoing challenges.
    • Objective biomarkers are needed to complement clinical assessments in evaluating antidepressant efficacy.
    • Previous research has explored various physiological and psychological markers in depression.

    Purpose:

    • To evaluate the utility of clinical interviews, psychological tests, Visual Evoked Potentials (VEPs), Thyrotropin-Releasing Hormone (TRH) tests, and plasmatic 3-methoxy-4-hydroxyphenylglycol (MHPG) levels in assessing treatment response in MDD patients.
    • To determine which of these methods provide reliable indicators of clinical improvement after antidepressant therapy.

    Summary:

    • Thirty MDD patients underwent assessments including clinical interviews, VEPs, psychological tests, TRH tests, and MHPG levels before and after a 28-day antidepressant treatment.

  • Analysis revealed that psychological tests and VEPs showed significant changes correlating with clinical status, indicating their value in monitoring treatment.
  • The TRH test provided no useful diagnostic information, and while MHPG levels identified patient subgroups, they did not correlate with treatment outcomes or specific depressive subtypes.

    • Impact:

    • Psychological tests and VEPs emerge as valuable tools for objectively assessing antidepressant treatment effectiveness in major depressive disorder.
    • Findings suggest that TRH testing and MHPG dosage may have limited utility in routine clinical monitoring of depression treatment response.
    • This study highlights the need for a multimodal approach, combining subjective and objective measures, for comprehensive depression management.
