Mood disorders are a group of mental health diseases that are characterized by various shifts and changes in an individual’s disposition. Subtle and severe changes in mood can affect a person’s temper and frame of mind, and ultimately impact how they communicate, sleep, and interact. Some examples of mood disorders include major depressive disorder, bipolar disorder, dysthymia, and seasonal depression. Meeting with a therapist, counselor, or psychiatrist to learn the skills needed to manage your mood disorder is helpful for living a healthy, positive, and personally successful life.
