F31: Bipolar affective disorder

Bipolar affective disorder, often known as bipolar disorder, is a group of mental health conditions characterized by drastic and significant shifts in mood, energy, and activity levels. These changes can range from periods of feeling euphoric, energetic, and overactive (known as mania) to episodes of feeling low and lethargic (known as depression), which may include feelings of sadness, hopelessness, and a lack of energy. The cause of bipolar disorder is not entirely known, but it's generally believed that both genetic and environmental factors play a significant role. Its onset is usually in late adolescence or early adulthood. The intensity and duration of these episodes can vary greatly from person to person and can severely impact a person's daily functioning--affecting their relationships, job performance, and overall quality of life. Bipolar disorder is not a condition that can be passed from one person to another, like a cold or flu.
