Mood disorders, or affective disorders, are mental health problems such as depression, bipolar disorder, and mania. Mood disorders can occur in anyone, including children. The cause of mood disorders is not fully understood, but an imbalance in brain chemicals known as neurotransmitters is likely to play a role.
Most people with bipolar disorder spend more time with depressive symptoms than manic or hypomanic symptoms. What Are the Symptoms of Bipolar Disorder? In bipolar disorder, the dramatic episodes of high and low moods do not follow a set pattern. Someone may feel the same mood state (depressed or manic) several times before switching to the opposite mood.
