For a diagnosis of Bipolar I disorder, what is required?

For a diagnosis of Bipolar I disorder, it is essential to have at least one episode involving an elevated mood and increased energy. This is a cornerstone criterion for the diagnosis, as Bipolar I is characterized by the presence of manic episodes, which are defined by prolonged periods of significantly altered mood and energy levels.

The manic episodes can vary in duration and intensity, but they fundamentally include symptoms such as increased activity, grandiosity, decreased need for sleep, and exuberant or irritably elevated mood. This manic phase distinguishes Bipolar I from other types of mood disorders, including Bipolar II, which requires hypomanic episodes instead of full manic episodes, alongside depressive episodes.

The requirement for an episode that features increased energy and elevated mood captures the essence of what makes Bipolar I disorder unique, reflecting its impact on functioning and behavior. Therefore, understanding manic symptoms is crucial for accurate diagnosis and treatment planning in clinical practice.
