Bipolar disorder patients with comorbid obsessive-compulsive disorder were significantly more likely to suffer from tic disorders, as well as hoarding, excoriation, and body dysmorphic disorder, than were those without comorbid OCD, data from 70 patients suggest.
Between 10% and 20% of patients with bipolar disorder (BD) also meet criteria for obsessive-compulsive disorder (OCD), and these patients are more likely to experience treatment resistance and poor prognosis than are BD patients without OCD. In addition, preliminary indications suggest a specific association between OCD and bipolar depression (BP-D) in particular, wrote Leonid Braverman, MD, of Ma’ale HaCarmel Mental Health Center, Tirat Carmel, Israel, and colleagues.
In addition, “there is compelling evidence indicating that OCD-spectrum and tic disorders share with OCD clinical characteristics, familial inheritance, neurobiological underpinnings and some aspects of pharmacotherapy,” and investigations into the clinical characteristics of OCD spectrum behaviors in BP-D patients with and without OCD are ongoing, they said.
In a study published in the Journal of Obsessive-Compulsive and Related Disorders (2021 Mar 21. doi: 10.1016/j.jocrd.2021.100643), the researchers reviewed data from 87 adults who met the DSM-5 criteria for BP-D. Of these, 27 also met criteria for OCD, 17 for subthreshold OCD, and 43 had neither OCD nor subthreshold OCD. The researchers compared the 27 OCD patients and the 43 non-OCD patients; the OCD patients had significantly higher rates overall of body dysmorphic disorder, hoarding disorder, excoriation disorder, and tic disorder, compared with non-OCD patients (P range from < .05-0.01 for all). No differences between the groups appeared for trichotillomania.
Also, the researchers found significant between-group differences in the number of patients with at least one OCD spectrum disorder and tic disorders (13 of 19 patients in the OCD group vs. 3 of 37 patients in the non-OCD group) and in the co-occurrence of two OCD-spectrum and tic disorders (3 of 19 patients in the OCD group vs. 1 patient in the non-OCD group).
The most common comorbid psychiatric disorders in both groups were substance use and combined anxiety disorders, followed by eating disorders, but no between-group differences were found in the frequencies of any of these conditions.
“From the clinical perspective, in BP-D patients,” the researchers noted.
The study findings were limited by several factors, including the small sample size, cross-sectional design, and exclusion of subsyndromic disorders, the researchers noted. However, the results support findings from previous studies, and the study emphasizes the clinical complexity and poor prognosis for these patients. Therefore, additional research is needed in patients with BP-D verse the manic/hypomanic phases of bipolar illness to determine similar patterns, they said. Medication trials are needed to address functional impairments in these patients, given the differences in treatment of BDD, hoarding, excoriation, and tic disorders, compared with “pure” OCD, they concluded.
The study received no outside funding. The researchers reported no financial conflicts.
