The characteristics of rapid cycling bipolar disorder is unclear and controversial. One reason for this is the lack of research on the concept. It is also because non-rapid cycling bipolar disorder has an unclear course and is variable amongst all individuals with the disorder. It is difficult to determine the  time frame of the episodes; when and how many episodes occur and how long they last.

Rapid cycling is a subtype of bipolar disorder characterized by the occurrence of at least four manic episodes, or a combination of at least four manic and major depressive episodes, within a one-year period.

Research has indicated that rapid cycling bipolar disorder causes more disruptions and impairments in an individual's every day life and functioning. They predominantly experience depressive episodes.  It may lead to more frequent episodes, greater numbers of hospitalizations, a worse response to pharmacotherapy, and are at a greater risk of attempting suicide.

Rapid Cycling Bipolar Disorder: Lack of Research 

Although results may not be completely generalizable, research has found that rapid cycling bipolar disorder is correlated with: 
- Gender (More common in women)
- Use of anti depressants 
- Comorbid ADHD

Rapid Cycling Bipolar Disorder: Correlations 

Rapid cycling bipolar disorder is often extremely difficult to treat. It does not respond to lithium treatment and there is limited research available on whether other mood stabilizers and anti- psychotics are effective.

Rapid Cycling Bipolar Disorder: Treatment Difficulties 

Due to the nature of bipolar disorder, it is difficult to determine the effectiveness of treatment over a short period of time. Therefore, treatment for rapid cycling bipolar disorder is most effective when it occurs over a period of 6-12 months.

Rapid Cycling Bipolar Disorder: Treatment 

Based on the 12-month history provided in the case study, would this patient's presentation meet the criteria for the 'rapid-cycling' specifier for their disorder? Justify your answer by referencing the specific diagnostic time frame and the number of mood episodes.
