Major contributors include:

Family history of depression
Chronic illnesses
Traumatic life events

Hormonal changes

Research from the National Institute of Mental Health (NIMH) shows that brain chemistry and hormonal imbalances also play a significant role.

Treatment and Management

Depression is treatable. Common approaches include:

Psychotherapy – Techniques like cognitive-behavioral therapy (CBT) can help modify negative thinking patterns.
Medication – Antidepressants can balance brain chemicals linked to mood regulation.
Lifestyle Changes – Regular exercise, a healthy diet, and sufficient sleep can improve symptoms.
Support Groups – Connecting with others who have similar experiences can reduce feelings of isolation.

The Mayo Clinic emphasizes that early treatment improves recovery outcomes.
