REVIEW
W Harth
Psychosomatic disorders of the scalp have some special characteristics due to the visibility, possible stigmatization, and amount/patterns of hair. Of practical relevance is trichotillomania, which is now classified as an obsessive-compulsive disorder (OCD). Patients who are obsessed with normal physiological hair loss represent a further psychodermatological challenge. Psychosomatic therapy includes basic psychosomatic care, behavior therapy, or treatment with psychopharmaceuticals.

BACKGROUND: Athina Markou and her colleagues discovered persistent changes in adult behavior following adolescent exposure to ethanol or nicotine consistent with increased risk for developing addiction. Building on Dr. Markou's important work and that of others in the field, researchers at the Bowles Center for Alcohol Studies have found that persistent changes in behavior following adolescent stress or alcohol exposure may be linked to induction of immune signaling in brain. AIM: This study aims to illuminate the critical interrelationship of the innate immune system (e...

BACKGROUND: Fear acquisition and extinction are central constructs in the cognitive-behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive-behavioral therapy. Youths with OCD may have impairments in fear acquisition and extinction that carry treatment implications. METHODS: Eighty youths (39 OCD, 41 healthy controls [HC]) completed clinical interviews, rating scales, and a differential conditioning task that included habituation, acquisition, and extinction phases...

RATIONALE: Early life stress combined with heavy adolescent alcohol use predicts impaired neuropsychological functioning in adulthood. We investigated whether adolescent intermittent ethanol (AIE) exposure combined with neonatal maternal separation in rats altered attentional processes and impulsivity in adulthood. METHODS: Male Wistar rat pups were exposed to maternal separation (postnatal days (PNDs) 1-14) and moderate AIE exposure (PNDs 28-57). Adult rats were tested in the five-choice serial reaction time task, which provides separate measures of attention, motor impulsivity, and compulsivity...

BACKGROUND: Cognitive behavior therapy (CBT) involving exposure and response prevention is the gold standard psychotherapeutic intervention for obsessive-compulsive disorder (OCD). However, applying traditional CBT techniques to treat patients with predominant obsessions (POs) without covert compulsions is fraught with problems because of inaccessibility of mental compulsions. In this context, we examined the efficacy of mindfulness-integrated CBT (MICBT) in patients with POs without prominent overt compulsions...

We recently showed that deep brain stimulation (DBS) in the bed nucleus of the stria terminalis (BST) reduces obsessions, compulsions and associated anxiety in patients suffering from severe, treatment-refractory obsessive-compulsive disorder. Here, we investigated the anxiolytic effects of electrical BST stimulation in a rat model of conditioned anxiety, unrelated to obsessions or compulsions. Two sets of stimulation parameters were evaluated. Using fixed settings at 100 Hz, 40 μs and 300 μA (Set A), we observed elevated freezing and startle levels, whereas stimulation at 130 Hz, 220 μs and individually tailored amplitudes (Set B) appeared to reduce freezing...

Global smartphone penetration has led to unprecedented addictive behaviors. To develop a smartphone use/non-use pattern by mobile application (App) in order to identify problematic smartphone use, a total of 79 college students were monitored by the App for 1 month. The App-generated parameters included the daily use/non-use frequency, the total duration and the daily median of the duration per epoch. We introduced two other parameters, the root mean square of the successive differences (RMSSD) and the Similarity Index, in order to explore the similarity in use and non-use between participants...

The mechanisms underlying social dysfunction in neuropsychiatric conditions like obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) remain uncertain. Dysfunctions in basal ganglia, including reduced number of striatal cholinergic interneurons (SCIN), have been involved in their pathophysiology. To explore the role of SCIN in relation to perseverative behaviors we characterized a new transgenic mouse model in which inducible ablation of SCIN is achieved with high efficiency in a cell-type and region specific manner...

We recently reported molecules designed according to the multi-target-directed ligand paradigm to exert combined activity at human fatty acid amide hydrolase (FAAH) and dopamine receptor subtype D3 (D3R). Both targets are relevant for tackling several types of addiction (most notably nicotine addiction) and other compulsive behaviors. Here, we report an SAR exploration of a series of biphenyl-N-[4-[4-(2,3-substituted-phenyl)piperazine-1-yl]alkyl]carbamates, a novel class of molecules that had shown promising activities at the FAAH - D3R target combination in preliminary studies...

The development of animal models of drug reward and addiction is an essential factor for progress in understanding the biological basis of this disorder and for the identification of new therapeutic targets. Depending on the component of reward to be studied, one type of animal model or another may be used. There are models of reinforcement based on the primary hedonic effect produced by the consumption of the addictive substance, such as the self-administration (SA) and intracranial self-stimulation (ICSS) paradigms, and there are models based on the component of reward related to associative learning and cognitive ability to make predictions about obtaining reward in the future, such as the conditioned place preference (CPP) paradigm...

BACKGROUND: Compulsive exercise, a form of unhealthy exercise often associated with prioritizing exercise and feeling guilty when exercise is missed, is a common precursor to and symptom of eating disorders. College-aged women are at high risk of exercising compulsively compared to other groups. Social network analysis (SNA) is a theoretical perspective and methodology allowing researchers to observe the effects of relational dynamics on the behaviors of people. METHODS: SNA was used to assess the relationship between compulsive exercise and body dissatisfaction, physical activity, and network variables...

Research has shown that brain regions mediating disgust (e.g., the insula) become activated when viewing others' disgust, a response mediated, perhaps by the mirror neuron system or the Theory of Mind module. In a novel behavioral experiment, we explore vicarious disgust and relief, in individuals with obsessive-compulsive disorder (OCD) symptoms. Participants (N = 10) provided disgust ratings to self-contamination or watching the contamination of an experimenter; and to the experimenter washing his own hands after the subjects had been contaminated...

Toshi, a 14-year-old Japanese boy, had uncontrolled asthma after relocating from Japan with his family 1 year ago. In Japan, he was diagnosed with moderate, persistent asthma, which was controlled with salmeterol and albuterol on an as needed basis. Since moving to the United States, Toshi complained of frequent dyspnea.Initially, he was seen by a Japanese physician who prescribed 200 mg of fluticasone 3 times a day and albuterol nebulization as needed. When Toshi came to the Pediatric Primary Care Clinic, he reported using his nebulizer up to 25 times daily...

Manic episodes are one of the major diagnostic symptoms in a spectrum of neuropsychiatric disorders that include schizophrenia, obsessive-compulsive disorder and bipolar disorder (BD). Despite a possible association between BD and the gene encoding phospholipase Cγ1 (PLCG1), its etiological basis remains unclear. Here, we report that mice lacking phospholipase Cγ1 (PLCγ1) in the forebrain (Plcg1(f/f); CaMKII) exhibit hyperactivity, decreased anxiety-like behavior, reduced depressive-related behavior, hyperhedonia, hyperphagia, impaired learning and memory and exaggerated startle responses...

In the contemporary milieu, the term "addiction" brings to mind issues of physical dependence, uncontrolled behavior, psychoactive substances, and disease. Thus, the use of the term "food addiction" which has become common in research on binge eating and obesity, suggests a disease state characterized by craving, compulsive eating and, possibly, the presence of food constituents with drug-like properties which weaken the will power to abstain from consumption. In this commentary, the case is made that, following the trends in substance use disorder terminology, adoption of "food use disorder" as a term for compulsive eating associated with subjective loss of control may foster continued research in this area without the connotations suggested by "food addiction...
