Depressive disorder, also known as major depressive disorder or clinical depression, is a common mental health condition characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities. It can significantly impact a person's daily life, relationships, and ability to function effectively. Individuals with depressive disorder may experience a range of symptoms, including changes in appetite, sleep disturbances, fatigue, difficulty concentrating, and thoughts of self-harm or suicide. The exact causes of depressive disorder are not fully understood, but a combination of genetic, biological, environmental, and psychological factors are believed to contribute to its development. Treatment for depressive disorder typically involves a combination of therapy, medication, and lifestyle changes. Cognitive-behavioral therapy and medication such as antidepressants are commonly used to help manage symptoms and improve overall mental well-being. It is important for individuals with depressive disorder to seek help from a mental health professional, as early intervention and treatment can greatly improve their quality of life.
