Summary
Psychotic major depression (PMD) patients showed poorer social functioning than nonpsychotic major depression (NPMD) patients. Higher cortisol levels at one year, but not baseline, correlated with worse outcomes in depressed individuals.
Area of Science:
- Psychiatry
- Endocrinology
- Clinical Psychology
Background:
- Longitudinal biological markers and their relation to long-term outcomes in depression are under-researched.
- Understanding these relationships is crucial for improving treatment and prognosis in major depressive disorder.
Purpose of the Study:
- To compare 1-year symptomatic and functional outcomes between psychotic major depressed (PMD) and nonpsychotic major depressed (NPMD) patients.
- To investigate the association between baseline and 1-year cortisol levels (urinary and plasma) and 1-year outcomes in depressed patients.
Main Methods:
- A cohort of 42 depressed patients (9 PMD, 33 NPMD) and healthy controls were assessed at baseline and 1-year follow-up.
- Evaluations included clinical ratings (HDRS, BPRS), social and occupational functioning measures, and urinary/plasma cortisol levels.
Main Results:
- At 1-year, PMD patients exhibited significantly poorer social and occupational functioning compared to NPMD patients, despite similar symptom severity (HDRS, BPRS).
- Elevated urinary and plasma cortisol levels at 1 year were significantly correlated with poorer social and occupational functioning at 1 year, irrespective of residual depressive symptoms.
- Baseline cortisol levels did not predict 1-year social and occupational functioning.
Conclusions:
- While psychotic features in major depression do not necessarily predict symptom severity at 1 year, they are associated with significant functional impairment.
- Elevated cortisol levels in the latter stages of depression may serve as a biological marker for persistent functional deficits, independent of symptom levels.
