What disorder is characterized by manic episodes lasting more than one week?

Bipolar I Disorder is characterized by the presence of manic episodes that last at least one week, or any duration if hospitalization is necessary. During these episodes, individuals experience elevated mood, increased activity levels, and may exhibit impulsive or risky behaviors. This disorder can significantly affect a person's functioning and can lead to distress or impairment in various areas of life.

The distinction of having manic episodes lasting more than one week is a critical component that helps differentiate Bipolar I from other mood disorders, including Bipolar II Disorder, where the manic episodes are less severe and classified as hypomanic rather than fully manic. Understanding this distinction is vital for accurate diagnosis and appropriate treatment planning in mental health practice.
