ASK YOUR PSYCHIATRIST/MEDICAL DOCTOR

The main difference between Bipolar I and Bipolar II disorder lies in the severity and type of mood episodes experienced:

Bipolar I Disorder

• Manic episodes are the hallmark. These are severe, often requiring hospitalization, and can include psychosis (delusions, hallucinations).

• The person may also experience major depressive episodes, but depression is not required for a diagnosis.

• Manic episodes Might last at least 7 days, or are so severe that immediate medical care is needed.

Example: A person may go days without sleep, have grandiose ideas, and engage in risky behaviors—followed (or preceded) by deep depression.

Bipolar II Disorder

• Characterized by hypomanic episodes (a milder form of mania) and major depressive episodes.

• No full manic episodes occur.

• Hypomania Might lasts at least 4 days and doesn’t usually cause significant disruption or require hospitalization.

• 
  

Example: A person may feel unusually energetic, talkative, and productive for a few days, but not out of control—then experience weeks or months of debilitating depression.

Summary Table:

Feature	Bipolar I	Bipolar II
Mania	Full mania (severe)	Hypomania (mild/moderate)
Depression	May occur, not required	Required for diagnosis
Hospitalization	Common during mania	Rare
Psychosis	Possible in mania	Absent

Here’s a comparison of Bipolar I vs Bipolar II including their core features and typical treatment options:

Bipolar I vs. Bipolar II: Full Comparison

Feature	Bipolar I	Bipolar II
Type of Elevated Mood	Full mania	Hypomania (less intense than mania)
Depressive Episodes	Common, but not required for diagnosis	Required for diagnosis
Mania Duration	≥ 7 days, or any duration if hospitalization needed	≥ 4 days, not severe enough for hospitalization
Psychosis	Can occur during manic episodes	Not typical
Functioning Impairment	Often severe, may lead to hospitalization	Impairment usually mild during hypomania
Diagnosis Requirement	At least 1 manic episode	At least 1 hypomanic + 1 major depressive episode
Suicide Risk	High (especially with mixed episodes or depression)	Higher than Bipolar I due to more time spent in depression
Course of Illness	May have rapid cycling or mixed episodes	Often more time spent depressed than elevated
