How long does a hypomanic episode last?

A hypomanic episode is characterized by a period of persistently elevated, expansive, or irritable mood that lasts for at least four consecutive days. This duration is essential for the diagnosis as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). During this time, the individual experiences an increase in energy or activity levels and may exhibit behaviors such as decreased need for sleep, inflated self-esteem, racing thoughts, and increased talkativeness.

This specific duration differentiates hypomanic episodes from manic episodes, which typically last for at least one week, and this distinction is critical in the context of mood disorders. Understanding the timeline of hypomanic episodes helps in the accurate diagnosis and management of conditions such as Bipolar II disorder, where these episodes play a significant role.

The other response options do not accurately reflect the established criteria; for instance, episodes lasting at least two weeks, seven days, or more than 30 days pertain to other classifications of mood episodes or disorders, thereby rendering them incorrect for this question.
