Summary
Comorbid personality disorders (PDs) are frequent in euthymic bipolar patients, with cluster B PDs and borderline PD being the most common. This systematic review highlights the high prevalence of these conditions in bipolar disorder management.
Area of Science:
- Psychiatry
- Clinical Psychology
- Mental Health Research
Background:
- Bipolar disorder (BD) is a chronic mental health condition.
- Comorbid personality disorders (PDs) can complicate BD diagnosis and treatment.
- Assessing PDs in euthymic bipolar patients is crucial for comprehensive care.
Purpose of the Study:
- To systematically review the frequency of comorbid PDs in studies of euthymic bipolar patients.
- To determine the prevalence of different PD clusters and subtypes in this population.
Main Methods:
- A systematic literature search was conducted across PubMed, ciELO, and PsychINFO databases for articles published between 1997 and 2013.
- Three eligible empirical studies were identified after screening 1,249 papers.
- Data were extracted by two independent reviewers from a total sample of 376 euthymic bipolar patients.
Main Results:
- Over 41% of euthymic bipolar patients exhibited at least one comorbid PD.
- Cluster B PDs were most frequent (23.1%), followed by Cluster C (14.6%) and Cluster A (6.6%).
- Borderline PD (10.1%) was the most common subtype, followed by histrionic (7.7%) and obsessive-compulsive PD (7.4%).
Conclusions:
- Comorbid PDs are highly prevalent in euthymic bipolar patients.
- Cluster B PDs, particularly borderline PD, are the most common comorbidities.
- These findings underscore the importance of screening for PDs in individuals with bipolar disorder.

Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...
