Bipolar disorder is a mood disorder characterized by extreme changes in mood, ranging from episodes of mania and hypomania (elevated mood) to episodes of depression (extreme sadness). Within the classification of bipolar disorder, two main types are distinguished: bipolar disorder type I and bipolar disorder type II. Despite having similarities in terms of symptoms, these two subtypes present significant differences in terms of severity and clinical characteristics.
Bipolar Disorder Type I
Bipolar disorder type I is characterized by the presence of at least one manic episode that may be preceded or followed by episodes of depression or hypomania. Mania is the hallmark of this subtype and manifests itself in an abnormally elevated, expansive, or irritable mood, accompanied by symptoms such as increased energy, decreased need for sleep, racing thoughts, impulsive behaviors, and, in extreme cases, , delusions or hallucinations. These manic episodes are usually severe and may require hospitalization.

Bipolar Disorder Type II
On the other hand, bipolar disorder type II is characterized by the presence of episodes of hypomania (lower intensity mania) that alternate with episodes of depression. Unlike bipolar disorder type I, complete manic episodes do not occur in type II, which means that the symptoms of hypomania are not as severe as in mania but still affect the functioning of the individual and their environment.
Characteristics of Bipolar Disorder Type II:
- Presence of episodes of hypomania and depression.
- Complete manic episodes are not present.

Bipolar disorder Type II is often more difficult to diagnose than type I, as hypomanic episodes can be confused with habitual elevated mood or other mood disorders, such as cyclothymia. It is important to perform a thorough evaluation to differentiate between both subtypes and provide appropriate treatment according to the patient's specific needs.
Comparison between Bipolar Disorder Type I and Type II

- Nature of the episodes: Type I experiences full manic episodes, with more intense symptoms, while type II presents hypomania, which is less severe and does not reach the intensity of mania.
- Diagnosis and management Clinical: Bipolar disorder type I is often easier to diagnose due to clear evidence of manic episodes, in contrast to type II, which can be more challenging to correctly identify.
