Pain perception and physiological correlates in body-focused repetitive behavior disorders.

CNS Spectr 2022 Mar 22:1-8. Epub 2022 Mar 22.

Department of Psychiatry and Biobehavioral Sciences, University of California, Los Angeles, California, USA.

Background: Behaviors typical of body-focused repetitive behavior disorders such as trichotillomania (TTM) and skin-picking disorder (SPD) are often associated with pleasure or relief, and with little or no physical pain, suggesting aberrant pain perception. Conclusive evidence about pain perception and correlates in these conditions is, however, lacking.

Methods: A multisite international study examined pain perception and its physiological correlates in adults with TTM (n = 31), SPD (n = 24), and healthy controls (HCs; n = 26). Read More

A prospective clinical cohort-based study of the prevalence of OCD, obsessive compulsive and related disorders, and tics in families of patients with OCD.

BMC Psychiatry 2022 03 17;22(1):190. Epub 2022 Mar 17.

Chaim Sheba Medical Center, Post Trauma Center, Ramat-Gan, Israel.

Background: The lifetime prevalence of obsessive - compulsive disorder (OCD) is currently estimated at 2 - 3% and the prevalence in first-degree family members is estimated to range between 10 and 11%. Separating OCD from other anxiety disorders and including it into the new "obsessive - compulsive and related disorders" (OCRDs) category has had a dramatic impact on the diagnosis, while also contributing to the better understanding of the genetics of these disorders. Indeed, grouping OCD with body dysmorphic disorder (BDD), and body-focused repetitive behaviors such as trichotillomania (hair pulling), onychophagia (nail biting), and excoriation (skin picking) into the same diagnostic family has resulted in a much greater lifetime prevalence (> 9%).

A Hierarchical Personality Approach Toward a Fuller Understanding of Onychophagia and Compulsive Buying.

Psychol Rep 2022 Feb 11:332941211061696. Epub 2022 Feb 11.

New Kensington Campus, Penn State University , Kensington, PA, U.S.A.

Purpose: Employing a hierarchical model of personality, prior research suggests that cardinal traits such as conscientiousness and agreeability predict central traits such as materialism and need for arousal that in turn impact surface traits such as onychophagia and compulsive buying. More research is needed to explore additional central traits and their effect on onychophagia and compulsive buying. Thus, the goal of the current research is to examine how another central trait-negative perfectionism-impacts onychophagia and compulsive buying. Read More

Trichotillomania: What Do We Know So Far?

Skin Appendage Disord 2022 Jan 1;8(1):1-7. Epub 2021 Sep 1.

Phillip Frost Department of Dermatology and Cutaneous Surgery, University of Miami School of Medicine, Miami, Florida, USA.

Trichotillomania is defined as an obsessive-compulsive or related disorder in which patients recurrently pull out hair from any region of their body. The disease affects mainly female patients, who often deny the habit, and it usually presents with a bizarre pattern nonscarring patchy alopecia with short hair and a negative pull test. Trichoscopy can reveal the abnormalities resulting from the stretching and fracture of hair shafts, and biopsy can be necessary if the patient or parents have difficulties in accepting the self-inflicted nature of a trichotillomania diagnosis.
