Depressive Disorders

Depressive disorders are a group of mental health conditions characterized by persistent sadness, emptiness, and loss of interest or pleasure in everyday activities. Unlike temporary feelings of sadness, depression involves symptoms that are intense, long-lasting, and interfere with a person’s ability to function at work, school, or in social situations. These disorders can also affect physical health, leading to changes in sleep, appetite, and energy levels. Depression is one of the most common mental health conditions worldwide, but with early diagnosis and proper treatment, individuals can experience significant recovery and improved quality of life.
