Abstract
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.

Abstract
OBJECTIVE Our goals were to examine clinical characteristics and age and gender correlates in pediatric trichotillomania. METHOD A total of 62 children (8-17 years of age) were recruited for a pediatric trichotillomania treatment trial and characterized using structured rating scales of symptoms of hairpulling and common comorbid conditions. We analyzed the association between qualitative and quantitative characteristics of pulling, comorbidities, and age and gender. We also examined the type of treatments these children previously received in the community. RESULTS We found lower rates of comorbid depression and anxiety disorders than have been reported in adult trichotillomania samples. Focused hairpulling significantly increased with age, whereas automatic pulling remained constant. Older children with hairpulling experienced more frequent urges and a decreased ability to refrain from pulling. Female participants reported greater distress and impairment associated with hairpulling, even though the severity of pulling did not differ from that of male participants. CONCLUSION These results confirm several findings from the Children and Adolescent Trichotillomania Impact Project (CA-TIP). Our cross-sectional findings suggest there may be a developmental progress of symptoms in trichotillomania. Children appeared to develop more focused pulling, to become more aware of their urges, and to experience more frequent urges to pull, as they get older. Although these are important findings, they need to be confirmed in prospective longitudinal studies.

Abstract
Trichotillomania is currently classified as an impulse control disorder not otherwise classified, whereas body-focused behaviors other than hair-pulling may be diagnosed as stereotypic movement disorder. A number of disorders characterized by repetitive, body-focused behaviors (eg, skin-picking) are prevalent and disabling and may have phenomenological and psychobiological overlap. Such disorders deserve greater recognition in the official nosology, and there would seem to be clinical utility in classifying them in the same diagnostic category.

Abstract
Although trichotillomania and pathological skin-picking are both characterized by repetitive self-injurious stereotypic behaviors, the former is classified as an impulse control disorder, while the latter is not given a specific diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders (4th edition) [APA, 1994]. There are, however, few empirical data on phenomenological similarities and differences between these disorders. Patients with trichotillomania and pathological skin-picking were compared in terms of several demographic (age, gender), clinical (comorbid axis I and II disorders), and personality variables. Trichotillomania and pathological skin-picking were very similar in demographics, psychiatric comorbidity, and personality dimensions. Dissociative symptoms may be more common in trichotillomania than in pathological skin-picking. These data support the concept of phenomenological overlap between trichotillomania and pathological skin-picking. Future work to assess the implications of overlap for clinical evaluation and intervention in the two conditions may be useful.

Abstract
This study was designed to detail the demographic and phenomenological features of adult chronic hair-pullers. Key possible subtypes were identified a priori. On the basis of the phenomenological data, differences between the following possible subtypes were investigated: hair-pullers with and without DSM-IV trichotillomania (TTM), oral habits, automatic versus focused hair-pulling, positive versus negative affective cues prior to hair-pulling, comorbid self-injurious habits, obsessive-compulsive disorder (OCD), and tics. Forty-seven participants were drawn from an outpatient population of chronic adult hair-pullers. A structured interview that focused on hair-pulling and associated behaviors was administered to participants. Six of the participants (12.8%) were male, and 41 (87.7%) were female. A large number of hair-pullers (63.8%) had comorbid self-injurious habits. A greater proportion of male hair-pullers had comorbid tics when compared with females. Certain subgroups of chronic hair-pullers (e.g., hairpullers with or without automatic/focused hair-pulling, comorbid self-injurious habits, and oral habits) were found to differ on a number of phenomenological and hair-pulling characteristics. However, differences between other possible subgroups (e.g., hair-pullers with or without DSM-IV TTM, comorbid OCD, and negative versus positive affective cues) may reflect greater severity in hair-pulling symptomatology rather than distinct subtypes of chronic hair-pulling. The findings of the present study also indicated that chronic hair-pulling (even in cases where DSM-IV criteria for TTM were not met) has a significant impact on quality of life. The present study provided limited support for the existence of possible subtypes of chronic hair-pulling. Recommendations are made for further investigations into such subtypes.

Abstract
Trichotillomania is a little-known disorder with wider prevalence and more significant consequences than previously believed. While sharing similarities with obsessive-compulsive disorder, compelling differences from it have also been noted. This fact, coupled with recognized overlap with other obsessive-compulsive spectrum disorders, has resulted in the ongoing evolution of our conceptualization of this illness. While empirical evidence supports the use of behavioral treatment and pharmacotherapy, considerable research is still needed before we can promise highly effective interventions tailored to the individual hairpuller. This review will summarize the evidence supporting, as well as challenging, a hypothesized link with obsessive-compulsive disorder. Current treatment approaches will be reviewed, as well as evidence for their efficacy. Suggestions will be made for future directions in this field.

Abstract
Eleven chronic hair pullers, 11 subjects with obsessive-compulsive disorders (OCD), and 11 subjects with a non-OCD anxiety disorder were assessed with structured interviews and the Child Behavior Checklist (CBCL). Only 4 hair pullers (36%) reported both rising tension and relief with hair pulling. Each group had significantly more internalizing than externalizing symptoms on the CBCL. Seven hair pullers (64%) had a lifetime history of at least one other axis I diagnosis. The results provide further evidence that trichotillomania in referred children and adolescents is usually a chronic disorder often associated with internalizing symptoms and psychiatric comorbidity. Rising tension followed by relief with hair pulling may be an unnecessary restriction in the diagnosis of childhood trichotillomania.

Abstract
Given recent conceptualizations of trichotillomania (TM) as a variant of obsessive compulsive disorder (OCD), clinician-rated measures of obsessive compulsive symptoms have been adapted for use in the assessment of TM. Although the reliability and validity of these instruments have been well-documented in patients with OCD, psychometric properties have not been examined systematically in patients with TM. Here, we evaluate the reliability and validity of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) in a sample of 11 patients with a primary diagnosis of TM. Data addressed the utility of the Y-BOCS for evaluating symptoms of TM, and provided information regarding the proposed overlap between OCD and TM. Initial analyses suggested that interrater reliability, internal consistency, and test-retest reliability for the total score were adequate. However, the range of scores was somewhat restricted, and suggested in particular that interference in daily functioning from TM symptoms is quite low. Both internal consistency and test-retest reliability for the Target Behaviors subscale were inadequate, suggesting that this combined score is inappropriate for use with TM patients. Concurrent validity data using the total score were mixed, although the Y-BOCS did appear to be sensitive to change in TM symptoms over treatment. Implications for the use of the Y-BOCS with TM patients and hypothesized phenomenological differences between TM and OCD are discussed.

Abstract
Trichotillomania is a neglected neuropsychiatric disorder that only recently has received research attention. Based on clinical data, it appears far more common than previously believed. Like OCD, the behavior is recognized as senseless and undesirable, but is chronic and difficult to treat. The comorbidity, drug response data, familiality, and phenomenology of the disorder extend the concept of OCD to a spectrum of inappropriately released, excessive grooming behaviors. Although the discovery of clomipramine's effectiveness has provided relief to some trichotillomanics, further work is indicated to find regimens that provide long-term suppression of symptoms. Ongoing investigations of early-onset trichotillomania may reveal etiologic triggers, whereas studies that examine the similarities and differences between trichotillomania and OCD may help define the neurobiology of OCD, and possibly of other atypical impulse control disorders.
