Mood Disorders are a group of mental health conditions that affect a person’s emotional state, causing persistent sadness, irritability, extreme mood swings, or fluctuations between high and low moods. These disorders disrupt daily functioning, relationships, work performance, and overall well-being. Common causes include genetic factors, chemical imbalances in the brain, long-term stress, trauma, or underlying medical conditions. Mood Disorders include depression, bipolar disorder, dysthymia, and cyclothymia. With proper diagnosis and treatment through medication, psychotherapy, and lifestyle changes, individuals can achieve emotional stability and significantly improve their quality of life.
