BACKGROUND: The management of trichotillomania is challenging. The limited efficacy and side-effects of pharmacological medications and difficulty in long-term maintenance of behavioural therapies necessitates alternative treatment options. A dysregulated glutamatergic system has been implicated in the pathophysiology of trichotillomania. A limited number of reports indicate that N-acetylcysteine (NAC), a glutamate modulator, may be a promising treatment for this disorder. OBJECTIVES: We report two patients with trichotillomania for whom treatment with NAC was successful...

OBJECTIVE: To assess the utility of N-acetylcysteine administration for depressive symptoms in subjects with psychiatric conditions using a systematic review and meta-analysis. DATA SOURCES: A computerized literature search was conducted in MEDLINE, Embase, the Cochrane Library, SciELO, PsycINFO, Scopus, and Web of Knowledge. No year or country restrictions were used. The Boolean terms used for the electronic database search were (NAC OR N-acetylcysteine OR acetylcysteine) AND (depression OR depressive OR depressed) AND (trial)...

Intrusive thinking triggers clinical symptoms in many neuropsychiatric disorders. Using drug addiction as an exemplar disorder sustained in part by intrusive thinking, we explore studies demonstrating that impairments in corticostriatal circuitry strongly contribute to intrusive thinking. Neuroimaging studies have long implicated this projection in cue-induced craving to use drugs, and preclinical models show that marked changes are produced at corticostriatal synapses in the nucleus accumbens during a relapse episode...

BACKGROUND: Current pharmacological treatments for Tourette Syndrome (TS), such as antipsychotic agents and α-2 agonists, are moderately effective in the treatment of tics, but have substantial side effects that limit their use. N-acetylcysteine (NAC) modulates glutamatergic systems, and has been used safely as an antioxidant agent with minimal side effects for decades. NAC has been increasingly studied for the treatment of other obsessive-compulsive spectrum disorders. We aim to examine the efficacy of NAC for the treatment of pediatric TS in a double-blind, placebo-controlled, add-on study...

Skin Picking Disorder affects 4% of the general population, with serious quality of life impacts, and potentially life threatening complications. Standard psychoactive medications do not help most patients. Similarly, Mouse Ulcerative Dermatitis (skin lesions caused by excessive abnormal grooming behavior) is very common in widely used inbred strains of mice, and represents a serious animal welfare issue and cause of mortality. Treatment options for Ulcerative Dermatitis are largely palliative and ineffective...

OBJECTIVE: To examine long-term outcome in children with trichotillomania. METHOD: We conducted follow-up clinical assessments an average of 2.8 ± 0.8 years after baseline evaluation in 30 of 39 children who previously participated in a randomized, double-blind, placebo-controlled trial of N-acetylcysteine (NAC) for pediatric trichotillomania. Our primary outcome was change in hairpulling severity on the Massachusetts General Hospital Hairpulling Hospital Hairpulling Scale (MGH-HPS) between the end of the acute phase and follow-up evaluation...

N-acetylcysteine (NAC) is recognized for its role in acetaminophen overdose and as a mucolytic. Over the past decade, there has been growing evidence for the use of NAC in treating psychiatric and neurological disorders, considering its role in attenuating pathophysiological processes associated with these disorders, including oxidative stress, apoptosis, mitochondrial dysfunction, neuroinflammation and glutamate and dopamine dysregulation. In this systematic review we find favorable evidence for the use of NAC in several psychiatric and neurological disorders, particularly autism, Alzheimer's disease, cocaine and cannabis addiction, bipolar disorder, depression, trichotillomania, nail biting, skin picking, obsessive-compulsive disorder, schizophrenia, drug-induced neuropathy and progressive myoclonic epilepsy...

INTRODUCTION: Individuals affected by trichotillomania (TTM) (hair-pulling disorder) consciously or non-consciously pull out their own body hair. The disorder has recently been incorporated into a chapter entitled, 'Obsessive-Compulsive and Related Disorders' in the diagnostic and statistical manual of mental disorders, fifth edition. AREAS COVERED: The review describes the literature currently available on the pharmacotherapy for TTM, including both randomized controlled trials and open-label trials of pharmacotherapy for TTM in adults or children...

BACKGROUND: Trichotillomania (TTM) (hair-pulling disorder) is a prevalent and disabling disorder characterised by recurrent hair-pulling. The effect of medication on trichotillomania has not been systematically evaluated. OBJECTIVES: To assess the effects of medication for trichotillomania in adults compared with placebo or other active agents. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials and the Cochrane Depression, Anxiety and Neurosis Group Register (to 31 July 2013), which includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years); EMBASE (1974 to date); MEDLINE (1950 to date) and PsycINFO (1967 to date)...

Trichotillomania is as medical condition caused by the patient himself by pulling out of is own hair, resulting in a perceptible hair loss pattern that frequently is associated with other psychiatric processes. Generally has a chronic course in most patients, and a challenging therapeutical management. There are several available options for is treatment, but the clinical response is not satisfactory in many patients. Recently, N-acetylcisteine, a glutamate modulator, has shown efficacy in the treatment of trichotillomania and other compulsive behaviors, and is considered a new alternative in the management of this condition...

Hair pulling disorder (HPD; trichotillomania) is characterized by recurrent pulling of hair from the scalp, eyebrows or other parts of the body. Skin picking disorder (SPD) is closely related to HPD and involves re-current picking of the skin. Even though both HPD and SPD are relatively common and potentially severe disorders, health professionals typically know little about them. In the present article, we describe the clinical characteristics of these problems and provide diagnostic guidelines. We also discuss main treatment approaches (drug treatments and behavior therapy) and review research on their efficacy...

BACKGROUND: In Obsessive Compulsive Disorder (OCD) current standard pharmacotherapies may be of limited efficacy. Non-conventional interventions such as Complementary and Alternative Medicine (CAM), self-help techniques, and lifestyle interventions are commonly used by sufferers of OCD, however to date no systematic review of this specific area exists. METHODS: We conducted a systematic review of studies using CAM, self-help, and lifestyle interventions for treatment of OCD and trichotillomania (TTM)...

N-acetyl-cysteine, N-acetylcysteine, N-acetyl cysteine, and N-acetyl-L-cysteine are all designations for the same compound, which is abbreviated as NAC. NAC is a precursor to the amino acid cysteine, which ultimately plays two key metabolic roles. Through its metabolic contribution to glutathione production, cysteine participates in the general antioxidant activities of the body. Through its role as a modulator of the glutamatergic system, cysteine influences the reward-reinforcement pathway. Because of these functions, NAC may exert a therapeutic effect on psychiatric disorders allegedly related to oxidative stress (e...

CONTEXT: Trichotillomania is characterized by repetitive hair pulling that causes noticeable hair loss. Data on the pharmacologic treatment of trichotillomania are limited to conflicting studies of serotonergic medications. N-acetylcysteine, an amino acid, seems to restore the extracellular glutamate concentration in the nucleus accumbens and, therefore, offers promise in the reduction of compulsive behavior. OBJECTIVE: To determine the efficacy and tolerability of N-acetylcysteine in adults with trichotillomania...
