Understanding the symptoms, causes, and triggers of rapid cycling in bipolar disorder
- Rapid cycling is a symptom of some bipolar patients that causes them to cycle through four or more episodes a year.
- Rapid cycling may be caused by substance abuse, severe life stressors, or trauma.
- Stopping medication, using antidepressants, and sleep disturbances can trigger rapid cycling.

What is rapid cycling bipolar disorder?
Bipolar disorder is a
These episodes tend to be short, with another occurring fairly soon after, hence the name rapid cycling. By contrast, people who are bipolar who don't experience rapid cycling typically have episodes that last weeks or months.
All bipolar disorder patients generally experience grace periods of normal mood in between episodes of depression and mania, but these periods are shorter for rapid-cycling patients.
What are the risks of rapid cycling?
Experiencing multiple depressive or manic episodes can take an immense toll on a person's life.
According to Lea Lis, MD, a board-certified psychiatrist with a clinical practice in Southampton, New York, rapid cycling can lead to the following:
- Loss of employment
- Failed relationships
- Problems maintaining social relationships
Rapid cycling not only disrupts the quality of life but it can be life-threatening, as well. A 2003 study published in JAMA Psychiatry followed 345 people with either bipolar 1 or 2. Of those studied, 89 experienced rapid cycling. Researchers determined that this condition put them at more than twice the risk of attempting suicide.
However, the same study found that in four out of five cases of rapid cycling, it stopped within two years of its first occurrence. Researchers are unclear why the condition resolved on its own, but believe rapid cycling may be only temporary for some patients.
What causes rapid cycling?
While researchers are still unsure exactly what causes rapid cycling, Lis says the risk factors to developing the condition are:
- Substance abuse
- Severe life stressors
- Family history
- Younger age at the time of bipolar onset
What triggers rapid cycling?
Rapid cycling appears to be triggered by both internal and external influences. A number of factors can trigger rapid cycling, some of which are more preventable than others. According to Lis, these primary triggers include:
- The use of substances such as amphetamines, alcohol, or marijuana.
- Skipping doses or stopping medication prescribed by a doctor.
- Use of antidepressants without a concurrent mood-stabilizing medication.
- Genetic differences that may cause sleep disturbances.
- Conditions such as hypothyroidism which is when the thyroid does not produce enough hormones or traumatic brain injury.
- Severe life stressors like childhood trauma or divorce.
How to treat rapid cycling
In order to successfully treat for rapid cycling, treatment plans must also address the underlying bipolar disorder symptoms.
Consistent therapy can teach patients coping skills — habits which people can integrate into their lives that help them deal with the issue at hand, says Anandhi Narasimhan, MD, a board-certified psychiatrist with her own private practice in Los Angeles, California.
For rapid cycling, coping skills that patients may find beneficial include getting a full eight hours of sleep, attending a support group, or journaling.
Generally, the use of antidepressants, especially for an extended period, is not advised for patients who experience rapid cycling, says Lis, as they may exacerbate symptoms.
Instead, she says mood-stabilizing drugs such as lithium or Depakote tend to be better treatment options for preventing future episodes as they decrease abnormal brain activity responsible for episodes.
However, doctors must monitor patients closely to ensure they continue the proper intake of these mood stabilizers and do not forego them if adverse side effects, such as weight gain, occurs, says Lis.

The bottom line
Rapid cycling is a symptom of bipolar disorder that some, but not all, people experience. It cannot be cured, but with proper medication and therapy, it can be managed.
"Symptoms can wax and wane at different times in life without treatment and sometimes with treatment when a person is faced with stress," says Narasimhan. "Maintenance treatment can help prevent future episodes or at least mitigate the severity of symptoms."
