Mood disorders are conditions that can cause significant changes or abnormalities in an individual's mood, which can negatively impact their ability to carry out daily activities. Some of the common mood disorders include major depression, bipolar spectrum disorders, seasonal affective disorder, premenstrual dysphoric disorder, and persistent depressive disorder (dysthymia). Symptoms of mood disorders can range from periods of intense sadness (depression) with loss of interest in activities that were once enjoyable, changes in eating habits or weight, sleeping issues, fatigue, feelings of sadness, feeling emotionally flat or empty, difficulty concentrating, and thoughts of dying or suicide to episodes of elevated mood and energy (mania or hypomania). Both medication management and therapy are beneficial for effectively managing symptoms.
