Manic episode

A manic episode is a period when a person experiences extremely high energy levels, intense mood changes, and unusual behavior that is very different from their normal self. It affects the brain, which controls mood, thoughts, and behavior. During a manic episode, people may feel overly happy or irritable, have racing thoughts, and talk very fast. They might also take risks without thinking about the consequences, such as spending a lot of money or engaging in unsafe activities. These changes can make it hard to function at work, school, or in relationships. The episode usually lasts for at least a week and can be very disruptive to daily life.

A manic episode is defined as a distinct period of abnormally and persistently elevated, expansive, or irritable mood lasting at least one week, accompanied by increased goal-directed activity or energy. It is a core feature of bipolar disorder and results from dysregulation of neurotransmitters such as dopamine and norepinephrine in the central nervous system. The episode is characterized by symptoms including inflated self-esteem or grandiosity, decreased need for sleep, pressured speech, flight of ideas, distractibility, increased involvement in risky activities, and psychomotor agitation. This state significantly impairs social or occupational functioning or may necessitate hospitalization to prevent harm. The pathophysiology involves altered neural circuits in the prefrontal cortex and limbic system. Recognizing a manic episode is critical due to its association with increased risk of suicide and functional decline.
