Depression is a common but serious mood disorder characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities that were once enjoyable, lasting for at least two weeks and significantly impairing daily functioning. It affects how a person thinks, feels, and handles everyday activities such as sleeping, eating, and working, and can range from mild and manageable to severe and disabling. Depression arises from a complex interplay of biological, psychological, and social factors rather than simple sadness or a personal weakness. It is highly treatable, though it often goes undiagnosed and untreated due to stigma and lack of awareness.

What are the main symptoms of Depression?

The most common symptoms include: Persistent sad or empty mood; loss of interest in previously enjoyed activities; changes in appetite or weight; sleep disturbances. Early recognition is key to prompt diagnosis and effective treatment.

Is Depression contagious?

No, Depression is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

How is Depression treated?

Treatment options include: Treatment typically combines psychotherapy; such as cognitive behavioral therapy; with antidepressant medications that help regulate brain chemistry. Treatment should always be guided by a qualified Psychiatry specialist. Do not self-medicate.

Can Depression be prevented?

While Depression cannot always be fully prevented, several measures can reduce risk: Building strong social support networks; regular physical activity; adequate and consistent sleep.

When should I see a doctor for Depression?

Consult a Psychiatry specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
