Quick Facts:
- Bipolar I involves mania, while Bipolar II involves hypomania and major depression.
- Bipolar II is not simply a less serious form of Bipolar I. Depressive episodes can significantly affect daily functioning.
- Bipolar disorder is usually treated with medication, therapy, or a combination of both.
- New Journeys Behavioral Health provides inpatient mental health treatment in Irvine for adults who need more structure and support.
Bipolar I and Bipolar II are both forms of bipolar disorder, but they can affect mood, energy, behavior, and daily life in different ways. The main difference comes down to the types of mood episodes a person experiences. Bipolar I involves at least one manic episode, while Bipolar II involves hypomanic episodes and major depressive episodes without a history of full mania.
Understanding the difference can make it easier to recognize symptoms and find the right level of mental health treatment.
What Is the Difference Between Bipolar I and Bipolar II?
The clearest difference between Bipolar I and Bipolar II is mania versus hypomania.
With Bipolar I, a person has experienced at least one manic episode. Mania causes a major change in mood and energy that lasts at least seven days, most of the day, nearly every day, or is severe enough to require hospital care. Someone may sleep very little, talk rapidly, have racing thoughts, become unusually confident or irritable, or make impulsive decisions. Severe mania can also include psychosis. (nimh.nih.gov)
With Bipolar II, a person experiences hypomanic episodes and major depressive episodes. Hypomania involves many of the same changes in mood and energy as mania, but symptoms are less severe and do not cause the same level of impairment. Bipolar II does not include a history of full mania (nimh.nih.gov). However, Bipolar II should not be thought of as “mild bipolar disorder.” Depression can be severe and may have a major impact on someone’s ability to work, maintain relationships, or manage everyday responsibilities.
Because mania and hypomania can sometimes be difficult to recognize, a professional mental health assessment is important for understanding a person’s full history of mood episodes, symptoms, and behaviors and determining whether they meet the criteria for Bipolar I, Bipolar II, or another condition.
What Do Bipolar Episodes Look Like?
Bipolar disorder involves more than ordinary changes in mood. Episodes can last for days or longer and cause noticeable changes in how someone thinks, feels, sleeps, and behaves.
During mania or hypomania, someone may have unusually high energy, need very little sleep, talk more or faster than usual, feel extremely confident, become easily distracted, or engage in impulsive or risky behavior. During a depressive episode, the pattern changes. Someone may experience persistent sadness, hopelessness, low energy, difficulty concentrating, changes in sleep or appetite, loss of interest, or thoughts of death or suicide. And depression can significantly affect functioning. According to SAMHSA’s 2025 National Survey on Drug Use and Health, 13.8 million U.S. adults experienced a major depressive episode with severe impairment in 2025.
When Is Inpatient Treatment Needed?
Many people manage bipolar disorder through ongoing psychiatric and outpatient care. However, there are times when symptoms become too severe to safely manage with occasional appointments alone. Signs that a higher level of mental health care may be needed include:
- Severe manic or depressive episodes
- Going for extended periods with very little or no sleep
- Hallucinations, delusions, or other symptoms of psychosis
- Suicidal thoughts or self-harming behavior
- Impulsive or risky behavior that creates safety concerns
- Extreme agitation, aggression, or major changes in behavior
- Difficulty taking medications consistently or managing symptoms at home
- Being unable to keep up with basic daily needs or responsibilities
- Symptoms that continue to worsen despite outpatient treatment
Inpatient mental health treatment in Irvine, CA, provides a structured environment with greater supervision and support. It also gives the treatment team an opportunity to closely evaluate symptoms, medications, sleep, behavior, and other factors that may be affecting mood while helping the person regain stability.
What Happens During Bipolar Treatment?
Bipolar treatment is personalized because the symptoms and needs of someone with Bipolar I may look very different from those of someone with Bipolar II. Medication management is often an important part of treatment. Mood stabilizers and atypical antipsychotics are commonly used to control symptoms and reduce the risk or severity of future mood episodes. Medication may also be adjusted depending on whether someone is experiencing mania or bipolar depression. (nimh.nih.gov)
Therapy works alongside psychiatric care. Cognitive behavioral therapy (CBT) can help clients recognize unhelpful thought and behavior patterns and develop healthier ways to respond. Family-focused therapy can improve communication and help family members better understand bipolar disorder and warning signs of an episode. Interpersonal and social rhythm therapy focuses on relationships and maintaining consistent daily routines, including sleep. NIMH identifies each of these as psychotherapy approaches that may be used as part of bipolar treatment.
Treatment may also include individual and group therapy, coping skills, stress management, sleep support, and planning for continued care after inpatient treatment. Long-term follow-up matters because bipolar disorder typically requires ongoing management. A 2025 NIMH research update noted that symptoms can return over time even though effective treatments are available.
Does Insurance Cover Inpatient Bipolar Treatment?
Private health insurance may cover inpatient or residential mental health treatment when the level of care is considered medically necessary. The amount covered depends on the individual policy, provider network, deductible, coinsurance, and any authorization requirements. New Journeys Behavioral Health works with most private insurance. Depending on the specific plan and benefits, coverage may be available through major private insurers and networks such as Anthem Blue Cross Blue Shield, Aetna, Cigna, and more.
Insurance coverage is different for every person, so it is important to verify benefits before admission. The admissions team can check your plan, explain available benefits, and help you understand potential out-of-pocket costs before beginning treatment.
