What Is Bipolar Disorder?
Bipolar disorder is a chronic mental health condition that causes shifts in mood, energy, sleep, and behavior. Unlike everyday mood swings, bipolar episodes last days to weeks, significantly disrupt functioning, and respond to specialized psychiatric treatment.

Bipolar Mood Episodes
Types of Bipolar Disorder
Bipolar I
Defined by at least one manic episode lasting a week or more (or requiring hospitalization). Depressive episodes are common but not required for diagnosis. Treatment typically combines mood stabilizers, antipsychotics, and therapy.
Bipolar II
Defined by recurrent depressive episodes and at least one hypomanic episode — but no full mania. Often misdiagnosed as depression. Treatment emphasizes mood stabilization to prevent switches into hypomania.
Cyclothymia
A chronic, lower-intensity pattern of mood fluctuations lasting at least two years. Symptoms don’t meet full criteria for mania or major depression but cause meaningful impairment.
Other
Includes substance- or medication-induced bipolar disorder and bipolar disorder due to a medical condition. Diagnosis requires ruling out other causes of mood instability.

What Causes Bipolar Disorder?
Key Takeaway: There is no single cause. Genetics, biology, environment, and life experiences all contribute to risk.
Bipolar Disorder & Addiction
Substance use is common in bipolar disorder and complicates treatment. Many people self-medicate, but substances destabilize mood and increase relapse risk.
| Substance | Why People Use It | Risk |
|---|---|---|
| Alcohol | Emotional numbing | Worsens depression |
| Cocaine | Energy boost | Triggers mania |
| Methamphetamine | Euphoria | Triggers psychosis |
| Opioids | Escape from pain | Dependence, depression |
| Cannabis | Anxiety relief | Mood instability, psychosis risk |
Dual Diagnosis Treatment Matters
Treating bipolar disorder and addiction together produces the best outcomes.
How Bipolar Disorder Is Diagnosed
Treatment Options
Mood Stabilizers
First-line treatment. Lithium, lamotrigine, and valproate reduce the frequency and severity of episodes.
Antipsychotics
Used for acute mania, mixed episodes, and maintenance. Includes quetiapine, olanzapine, aripiprazole, and others.
Therapy
CBT, family-focused therapy, and interpersonal/social rhythm therapy reduce relapse and improve functioning.
Lifestyle
Consistent sleep, exercise, stress management, and avoidance of substances are protective and essential to stability.
Dual Diagnosis
Integrated treatment of bipolar disorder and substance use produces the strongest long-term outcomes.
Common Mood Stabilizers
