Adjustment disorder is a psychiatric condition characterized by the development of emotional or behavioral symptoms in response to an identifiable stressor occurring within three months of the onset of the stressor. Unlike major depressive disorder or post-traumatic stress disorder, the symptoms are disproportionate to the severity of the stressor or significantly impair social, occupational, or other important areas of functioning.

The etiology is multifactorial, stemming from the interaction between an external stressor (e.g., job loss, divorce, bereavement, chronic illness) and an individual’s subjective resilience. While genetic predisposition plays a minor role compared to major mood disorders, early life adversity and personality traits (e.g., neuroticism) significantly influence the threshold for development.

Pathophysiology involves dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and altered autonomic nervous system responsiveness. Chronic stress leads to sustained cortisol elevation, which impacts the hippocampus and amygdala. Neurochemically, there is often an imbalance in serotonin and norepinephrine signaling within the prefrontal cortex, which impairs executive function and emotional regulation.

Prevalence ranges from 5% to 20% in outpatient psychiatric populations. It is one of the most common diagnoses in primary care and general hospital settings. There is no clear gender predominance, though women are more likely to seek treatment. It can occur at any age, from childhood to late adulthood.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Rule out anemia/infection
Expected Findings: Normal
Interpretation: Normal findings exclude physical fatigue causes. Thyroid Stimulating Hormone (TSH)
Type: Blood Test
Purpose: Evaluate for hypothyroidism
Expected Findings: Normal
Interpretation: Abnormalities indicate metabolic, not primary psychiatric, causes.
