Chronic depression, also known as persistent depressive disorder or dysthymia, is a long-lasting form of depression that can affect a person's daily life. Symptoms may include feelings of sadness, low energy, and a lack of interest in activities for at least two years. Unlike major depressive episodes, the symptoms are less severe but can still significantly impact overall well-being. People with chronic depression may struggle with relationships, work, and self-esteem. Treatment options often include therapy, such as cognitive-behavioral therapy, and medications like antidepressants. Early intervention can help manage symptoms and improve quality of life.
