What is major depression?
Major depression is a common but serious mental health condition that affects how you feel, think, and function each day. It can make even simple tasks feel overwhelming and may impact your relationships, work, and physical health.
This condition is not a personal failure. It is linked to changes in brain chemistry and other factors, and it can be effectively treated with the right care.
Depression often develops from a combination of factors. These may include changes in brain chemistry, a family history of mood disorders, stressful life events, or ongoing health conditions. In some cases, it can begin without a clear cause.
Symptoms
Depression can look different for each person, but symptoms usually last most of the day for at least two weeks.
Common symptoms include:
- Ongoing sadness or a feeling of emptiness
- Loss of interest in hobbies or activities
- Changes in sleep or appetite
- Low energy or constant fatigue
- Trouble focusing or making decisions
- Feelings of guilt, worthlessness, or hopelessness
- Restlessness or slowed movement
- Thoughts of death or self-harm
How is it diagnosed?
To diagnose major depression, a healthcare provider or mental health professional will talk with you about your symptoms, medical history, and overall well-being. They may use screening tools or questionnaires to understand better how you’re feeling.
A diagnosis is typically made when symptoms last at least two weeks and interfere with daily life. Your provider may also check for other conditions that could be affecting your mood.
How is it treated?
Treatment for depression is personalized and often involves more than one approach.
Most people begin with medication, therapy, or both. If symptoms are severe or don’t improve, other treatments may be considered, including electroconvulsive therapy (ECT).
Healthy habits can also support recovery. Regular exercise, staying connected with others, and maintaining a routine can make a meaningful difference.
Many people begin to feel better within a few weeks of starting treatment. Staying consistent with care can help prevent symptoms from returning.
