Objective: Trichotillomania (TTM) is characterized by the pulling out of one's hair. TTM was classified as an impulse control disorder in DSM-IV, but is now classified in the obsessive-compulsive related disorders section of DSM-5. Classification for TTM remains an open question, especially considering its impact on treatment of the disorder. In this review, we questioned the relation of TTM to tic disorder and obsessive-compulsive disorder (OCD).
Method: We reviewed relevant MEDLINE-indexed articles on clinical, neuropsychological, neurobiological, and therapeutic aspects of trichotillomania, OCD, and tic disorders.
Results: Our review found a closer relationship between TTM and tic disorder from neurobiological (especially imaging) and therapeutic standpoints.
Conclusion: We sought to challenge the DSM-5 classification of TTM and to compare TTM with both OCD and tic disorder. Some discrepancies between TTM and tic disorders notwithstanding, several arguments are in favor of a closer relationship between these two disorders than between TTM and OCD, especially when considering implications for therapy. This consideration is essential for patients.

Article Synopsis
- Pediatric patients with trichotillomania (TTM) have a significantly increased risk of developing various psychiatric disorders compared to matched controls.
- The study involved a large case-control analysis using data from the TriNetX global research network, focusing on patients under 18 diagnosed with TTM.
- Results highlighted that TTM patients are particularly susceptible to conditions like ADHD, obsessive-compulsive disorder, and mood disorders, indicating the need for timely intervention and support from healthcare professionals.
Measuring Treatment Response in Pediatric Trichotillomania: A Meta-Analysis of Clinical Trials.

In clinical trials of pediatric trichotillomania (TTM), three instruments are typically employed to rate TTM severity: (1) the Massachusetts General Hospital Hair Pulling Scale (MGH-HPS), (2) the National Institute of Mental Health Trichotillomania Severity Scale (NIMH-TSS), and (3) the Trichotillomania Scale for Children (TSC). These instruments lack standardized definitions of treatment response, which lead researchers to determine their own definitions of response and potentially inflate results. We performed a meta-analysis to provide empirically determined accuracy measures for percentage reduction cut points in these three instruments.

Background: This study addresses the strength of associations between trichotillomania (TTM) and other DSM-IV Axis I conditions in a large sample (n = 2606) enriched for familial obsessive-compulsive disorder (OCD), to inform TTM classification.
Methods: We identified participants with TTM in the Johns Hopkins OCD Family Study (153 families) and the OCD Collaborative Genetics Study, a six-site genetic linkage study of OCD (487 families). We used logistic regression (with generalized estimating equations) to assess the strength of associations between TTM and other DSM-IV disorders.

This study compared youth ages 5-17 years with a primary diagnosis of trichotillomania (TTM, n = 30) to those with primary OCD (n = 30) and tic disorder (n = 29) on demographic characteristics, internalizing, and externalizing symptoms. Findings suggest that youth with primary TTM score more comparably to youth with tics than those with OCD on internalizing and externalizing symptom measures. Compared to the OCD group, youth in the TTM group reported lower levels of anxiety and depression.
