Mood Disorders
Depression
Depression is more than feeling sad or having a difficult day. It is a mental health condition that can affect your mood, energy, sleep, concentration, and interest in everyday activities. It can make even familiar tasks feel overwhelming and affect relationships, work, and daily life.
Depression can affect people differently, and symptoms may range from mild to severe. With an appropriate diagnosis and individualized care, many people find ways to manage their symptoms and improve their quality of life.

Overview
Understanding Depression
Depression, also known as major depressive disorder when specific diagnostic criteria are met, is a mental health condition that affects how a person feels, thinks, and manages daily activities. Unlike temporary sadness, depression can persist and interfere with everyday functioning, even when there is no obvious reason for feeling low. It can affect sleep, appetite, motivation, relationships, work, and the ability to enjoy activities that once felt rewarding. Some people experience persistent sadness, while others primarily notice fatigue, irritability, difficulty concentrating, or a loss of interest in things they previously enjoyed. Depression can develop at different stages of life and may occur alongside anxiety or other health conditions. Recognizing the symptoms and understanding their impact can help individuals identify when professional support may be useful.
Key Insight
Depression is a treatable mental health condition, although the type of treatment and the time it takes to experience improvement vary from person to person. Early assessment and an individualized treatment plan can help people address symptoms and work toward improved daily functioning.
Treatment Success
Depression care may involve psychotherapy, medication, or a combination of approaches. For some individuals, additional options, such as transcranial magnetic stimulation (TMS), may be considered when symptoms do not improve with initial treatments.

Brain chemistry imbalances
Genetic predisposition
Major life changes or trauma
Chronic medical conditions
