What are the two types of episodes associated with bipolar 1 disorder?

Bipolar I disorder is characterized by the presence of manic episodes, which are the hallmark of the disorder. These episodes can be severe and last at least seven consecutive days, or they may be so severe that immediate hospital care is needed. In addition to manic episodes, individuals with bipolar I disorder may also experience hypomanic episodes, which are similar but less intense and do not impair functioning as much, lasting for at least four consecutive days. It is important to note that the severity and duration differentiate these episodes and contribute to the overall diagnosis and management of bipolar I disorder.

While depressive episodes can also occur in bipolar I disorder, the question specifically asks for the types of episodes that are associated primarily with this condition. Therefore, the emphasis is on manic and hypomanic episodes, as they define the spectrum of bipolar I disorder.
