Understanding Bipolar Subtypes with Adelson Behavioral & Mental Health
Not all bipolar disorders are the same. While many people have heard of “bipolar disorder,” fewer know that there are actually different types—each with distinct symptoms and treatment needs. Bipolar I and Bipolar II are the most common subtypes, and understanding the difference can help individuals get the right diagnosis and care.
At Adelson Behavioral & Mental Health, we help clients understand the nuances of mental health diagnoses, including the complexities of bipolar disorder. Here’s how Bipolar I and Bipolar II differ—and what that means for treatment and daily life.

1. What Is Bipolar Disorder, Generally?
Bipolar disorder is a mood disorder marked by significant shifts in mood, energy, and activity levels. These shifts go beyond everyday ups and downs and can impair a person’s ability to function.
Key features of bipolar disorder include:
📉 Depressive episodes – Feelings of sadness, hopelessness, fatigue, or loss of interest
📈 Manic or hypomanic episodes – Elevated mood, increased energy, impulsive behavior
🔁 Periods of stable mood between episodes
🧠 Mood changes that disrupt work, relationships, and daily responsibilities
📅 Symptoms often develop in late teens or early adulthood (National Institute of Mental Health)
Understanding which subtype you have can influence both treatment and recovery strategies.
2. What Is Bipolar I Disorder?
Bipolar I is defined by the presence of at least one manic episode, which may or may not be followed by depressive episodes. Manic episodes can be severe and may require hospitalization.
Key characteristics of Bipolar I:
⚠️ Manic episodes last at least 7 days (or less if hospitalization is needed)
🗣 Symptoms include high energy, inflated self-esteem, reduced need for sleep, fast speech
😔 May include depressive episodes, but not always required for diagnosis
🏥 Higher risk for hospitalization due to severe mania or psychosis
📊 Episodes significantly impair functioning across multiple areas
Bipolar I is often the more recognizable and disruptive form, particularly during manic episodes.
3. What Is Bipolar II Disorder?
Bipolar II involves at least one major depressive episode and one hypomanic episode, but no full manic episodes. Hypomania is less intense than mania and usually doesn’t require hospitalization.
Key characteristics of Bipolar II:
📉 Long-lasting depressive episodes—often more frequent and severe
📈 Hypomanic episodes last at least 4 days
💡 Symptoms include increased energy, talkativeness, confidence—but not extreme behaviors
🧍 Individuals may appear “high functioning,” which can delay diagnosis
🔍 Often misdiagnosed as depression due to prominent low moods (Mayo Clinic)
Bipolar II is just as serious as Bipolar I but is sometimes misunderstood or overlooked.
4. Diagnosis and Treatment: Why the Distinction Matters
Getting the correct diagnosis between Bipolar I and II is essential, because each subtype may respond differently to certain medications and therapeutic approaches.
Treatment considerations include:
💊 Mood stabilizers are used in both types but may vary in dosage and type
🧠 Antidepressants are used with caution, especially in Bipolar I (to avoid triggering mania)
🗣 Therapy, including CBT and psychoeducation, is key for both types
📅 Long-term monitoring helps prevent relapse or identify early warning signs
🧍 Individualized care plans ensure treatment fits the person's needs and life
At Adelson Behavioral & Mental Health, we provide accurate assessment, diagnosis, and personalized care to help clients thrive, no matter their diagnosis.
Conclusion: Understanding the Difference Empowers Better Care
