Area of Science:

Psychiatry
Clinical Psychology
Neuroscience

Background:

Negative symptoms are a core feature of several psychiatric disorders.
Their prevalence and specific manifestations in major depressive disorder (MDD) require further investigation.
Understanding negative symptoms is crucial for comprehensive patient assessment.

Purpose of the Study:

To assess the frequency and types of negative symptoms in patients with major depression.
To explore potential correlations between demographic variables and the presence of specific negative symptoms.
To highlight the clinical implications of systematically evaluating negative symptoms in depression.

Main Methods:

Utilized the Scale for Assessment of Negative Symptoms (SANS) to evaluate 34 cases of major depression.

Collected demographic data for correlation analysis.

Statistical analysis to identify significant associations.

Main Results:

Negative symptoms were frequently observed in the studied major depression cohort.
The most common negative symptoms included inability to enjoy activities (76%), anhedonia (64.7%), and physical anergia (55.9%).
Poverty of speech was more prevalent in younger patients (P < .001), and avolition in unmarried patients (P < .05).

Conclusions:

Negative symptoms are a significant and common feature in major depression.
Specific negative symptoms show correlations with demographic factors like age and marital status.
Systematic assessment of negative symptoms in depression is recommended for future research, particularly for prognostication, treatment response, and classification.
