Mood disorders are mental health conditions that cause ongoing disturbances in mood and emotions. They include major depression, bipolar disorder, and dysthymia. Symptoms often involve persistent sadness, loss of energy, irritability, or sudden shifts between high and low moods. These conditions may affect daily life, relationships, and productivity. Management typically involves counseling, medication, and lifestyle changes, which help individuals regain stability, reduce symptoms, and improve overall mental well-being.
