Depression and Stress: How Stressful Life Events Can Trigger Depressive Episodes

Depression is not solely caused by stress, but stressful life events are significant risk factors. Major stressors—such as bereavement, financial hardship, trauma, or chronic illness—can precipitate depressive episodes in vulnerable individuals.

The relationship is bidirectional: chronic stress dysregulates the HPA axis and neurotransmitter systems, while depression impairs coping, creating a cycle. Effective treatment often addresses both stress management (therapy, lifestyle) and mood symptoms (medication, CBT).
