A young child participated in a functional analysis and treatment of hair twirling, a frequently occurring precursor to hair pulling. The functional analysis showed that hair twirling occurred mostly when the child was alone at bedtime. Noncontingent application of mittens decreased hair twirling to near-zero levels in two settings (home and day care).

BACKGROUND Many patients suffering from trichotillomania (TTM) have never undergone treatment. Without treatment, TTM often presents with a chronic course. Characteristics of TTM individuals who have never been treated (untreated) remain largely unknown. Whether treatment history impacts Internet-based interventions has not yet been investigated. We aimed to answer whether Internet-based interv...

This article was accepted fur publication September 26, 1991.

Treatments for persistent thumb-sucking, however, have shown minimal or transie...

Evidence suggests that abnormalities in the corticostriato-thalamic-cortical circuits are one of the key factors underlying the pathophysiology of OCDR, including trichotillomania. Particularly, orbitofrontal cortex, anterior cingulate and ventromedial striatum hypermetabolism has been linked to OCD (Ahmari et al., 2013). Glutamate is the primary neurotransmitter within the cortico-striatothala...

Trichobezoars are impactions of swallowed hairs in the stomach and occasionally in the intestine. They occur in emotionally disturbed, depressed, or mentally retarded patients who have trichotillomania and trichophagia. Trichobezoars are usually diagnosed on CT scan or upper GI endoscopy. They can give rise to complications like gastroduodenal ulceration, haemorrhage, perforation, peritonitis, ...

Given this dearth of information, the present investigation sought to examine the treatment practices of members of the nationally recognized Trichotillomania Learning Center–Scientific Advisory Board (TLC-SAB) and practitioners known by m...

In DSM-IV-TR, trichotillomania (TTM) is classified as an impulse control disorder (not classified elsewhere), skin picking lacks its own diagnostic category (but might be diagnosed as an impulse control disorder not otherwise specified), and stereotypic movement disorder is classified as a disorder usually first diagnosed in infancy, childhood, or adolescence. ICD-10 classifies TTM as a habit a...
