BACKGROUND: Psychiatric manifestations in Prader-Willi Syndrome (PWS) are common and often are the most debilitating problem in these individuals. We present an epidemiological nation-wide survey of psychiatric diagnoses in the PWS population, based on full-range psychiatric interviews. METHODS: We studied the distribution of psychiatric diagnoses (as opposed to a symptom-based approach) in the Israel national cohort of adolescents and adults with PWS. There was a total of 53 (32 males) ages 12 years and older...

OBJECTIVE: The syndemics framework has been used to explain the high rates of HIV infection among gay and bisexual men. However, most studies have relied primarily on urban or otherwise limited (e.g., single location) samples. We evaluated the prevalence of syndemics-here, depression, polydrug use, childhood sexual abuse, intimate partner violence, and sexual compulsivity-among gay and bisexual men from across the United States, including nonurban areas. METHOD: Using data from a national sample of 1,033 HIV-negative gay and bisexual men, demographic differences in the prevalence of each syndemic condition and associations with HIV transmission risk behavior were examined...

The lateral hypothalamus (LHA) integrates reward and appetitive behavior and is composed of many overlapping neuronal populations. Recent studies associated LHA GABAergic neurons (LHA (GABA) ), that densely innervate the ventral tegmental area (VTA), with modulation of food reward and consumption; yet, LHA (GABA) >VTA projections exclusively modulated food consumption, not reward. We identified a subpopulation of LHA (GABA) neurons that co-express the neuropeptide galanin (LHA (Gal) ). These LHA (Gal) neurons also modulate food reward, but lack direct VTA innervation...

Intermittent theta burst stimulation (iTBS), a patterned repetitive transcranial magnetic stimulation, was applied over the posterior superior temporal sulcus (pSTS) or dorsolateral prefrontal cortex (DLPFC) to explore its impact in adults with autism spectrum disorder (ASD). Among 25 adults with ASD, 19 (mean age: 20.8 years) completed the randomized, sham-controlled, crossover trial. Every participant received iTBS over the bilateral DLPFC, bilateral pSTS and inion (as a sham control stimulation) in a randomized order with a 1-week interval...

Background: Increased locomotor activity in response to the same stimulus is an index of behavioral sensitization observed in preclinical models of drug addiction and compulsive behaviors. Repeated administration of Quinpirole (QNP), a D2/D3 dopamine agonist, induces locomotor sensitization. This effect is potentiated and accelerated by co-administration of U69593, a kappa opioid receptor agonist (KOR). The mechanism underlying KOR potentiation of QNP-induced locomotor sensitization remains to be elucidated...

OBJECTIVES: Body dysmorphic disorder (BDD) is characterized by repetitive behaviors and/or mental acts occurring in response to preoccupations with perceived defects or flaws in physical appearance. There are some similarities, but also important differences, between BDD and obsessive-compulsive disorder (OCD), not just in terms of core clinical symptoms, but possibly in the domain of perception. This study compared the nature and extent of perceptual anomalies in BDD versus OCD and health controls (HC), using a modified Mooney task...

In Obsessive Compulsive Disorder (OCD), overvalued ideas (OVI) are considered poor prognostic indicators in adults. To date, OVI has not been studied in an adolescent population with OCD, nor has it been examined in relation to obsessive-compulsive beliefs. To investigate the relationship between OVI and specific cognitions, fifty-five adolescents with OCD (35 male; 20 female; age range 13-17 years; M=14.05 years, SD=1.75 years) participated. It was predicted that OVI would be associated with symptom severity and would moderate obsessive-compulsive beliefs and functional disability...

Addictive substances mediate positive and negative states promoting compulsive drug use. However, substrates for aversive effects of drugs are not fully understood. We found that inactivation of the lateral habenula (LHb) by microinjection of tetrodotoxin (TTX) abolished naloxone-precipitated conditioned place aversion (CPA) in morphine-dependent mice. We also found that lateral habenular administration of KN-62, a specific inhibitor for calcium/calmodulin dependent protein kinase II (CaMKII), abolished naloxone-precipitated CPA in morphine-dependent mice...

A great deal of studies suggests that cluster headache (CH) patients are usually comorbid to anxiety-mood spectrum disorders and psychopathological symptoms; however, the personality profiles reported in the literature strictly depend on type of assessment used. Psychiatric comorbidities have been extensively studied in migraine and they are recognized to represent a major risk factor associated with poorer outcome, playing a role in the headache chronification process at once as cause and consequence of it...

Cannabis is a widely spread drug which chronic abuse may cause diverse adverse effects on the body, in the short and long term. Among these effects, we can cite digestive disorders, mainly characterized by the onset of cyclical vomiting illness. Vomiting symptoms can be temporarily relieved by hot water showers. As a matter of fact, many patients adopt a compulsive bathing behavior characterized by the irrepressible need of having showers or baths at a high temperature. We describe the case of two patients (22 and 23 years-old) who consume cannabis on a regular basis...

AIM: to investigate peculiarities of psycho-emotional reactions in patients with central serous chorioretinopathy (CSCR). MATERIAL AND METHODS: The study involved 35 patients with CSCR (mean age of 47.7±8.5 years) and 26 volunteers without visual impairment (mean age of 35.8±4.5 years). Their psycho-emotional state was studied using the SCL-90-R questionnaire (the severity of psychopathological symptomatology), TOBOL method (the type of attitude to the disease), Ways of Coping Questionnaire (WCQ) (strategies for controlling behavior), Spielberger-Hanin method (the level of anxiety), and the VFQ-25 questionnaire (quality of life)...

Traumatic brain injury (TBI) occurs when a blow or jolt to the head or a penetrating injury results in damage to the brain. It is the most frequent cause of hospitalization in young people with a higher prevalence in men. TBI is the leading cause of disability and mortality between the ages 1 and 45. TBI can be caused either by the direct result of trauma or due to a complication of the primary injury. The most common etiological factors for TBI are falls, road traffic accidents, violent physical assaults, and injuries associated with athletic activities...

Previous research has shown strong connections of anger experience and expression with obsessive-compulsive (OC) symptoms. Additionally, studies have demonstrated links between family environment variables and obsessive-compulsive disorder (OCD). Our study aims to integrate the perspectives from these two literatures by exploring the moderating roles of family cohesion and family adaptability in the relationship between anger proneness and suppression and OCD symptoms. A total of 2008 college students were recruited from a comprehensive university in Shanghai, China between February and May 2016...

Compulsive buying is a relatively new addictive disorder that interferes with everyday functioning and may result in serious psychological and financial problems (1). A very few data are currently available regarding this behavioral addiction. This study investigated gender differences in the relationships between contingent self-esteem (CSE), fear of negative evaluation (FNE), and compulsive buying. Participants included 240 Italian adults (170 females, M age = 33.80) who responded to self-report questionnaires...

Personality disorders (PDs) are stable and enduring patterns of thought, feeling, and behavior that deviate from one's cultural norms and cause impairment in functionality. Patients with PDs are commonly encountered in the dermatologic setting and can be perceived by providers as "difficult." Given that PDs are chronic, rigid, and frustrating to deal with, it is important to be skillful in the approach to such patients, especially in the era of the value-based reimbursement system, in which patient satisfaction is crucial for reimbursement...

Impulsive and compulsive behaviors in Parkinson's disease (PD) patients are most often attributed to dopamine agonist therapy; dysregulation of the mesocorticolimbic system accounts for this behavioral phenotype. The clinical presentation is commonly termed impulse control disorder (ICD): Behaviors include hypersexuality, compulsive eating, shopping, pathological gambling, and compulsive hobby participation. However, not all PD individuals taking dopamine agonists develop these behavioral changes. In this review, the authors focus on the similarities between the phenotypic presentation of ICDs with that of other reward-based behavioral disorders, including binge eating disorder, pathological gambling, and substance use disorders...

Obsessive-compulsive disorder (OCD) is a chronic, disabling condition with inadequate treatment options that leave most patients with substantial residual symptoms. Structural, neurochemical, and behavioral findings point to a significant role for basal ganglia circuits and for the glutamate system in OCD. Genetic linkage and association studies in OCD point to SLC1A1, which encodes the neuronal glutamate/aspartate/cysteine transporter excitatory amino acid transporter 3 (EAAT3)/excitatory amino acid transporter 1 (EAAC1)...

BACKGROUND AND OBJECTIVES: To address the fact that not all individuals who receive cognitive-behavioral therapy (CBT) for obsessive-compulsive disorder (OCD) exhibit complete symptom reduction, research has examined factors that predict outcome; however, no studies have examined anxiety sensitivity (AS) as a predictor of outcome of CBT for OCD. AS refers to the fear of anxious arousal that results from mistaken beliefs about the dangerousness of anxiety-related body sensations. It is important to understand whether AS influences OCD treatment outcome, considering that (a) some obsessions directly relate to AS, and (b) OCD patients with high AS may be reluctant to engage in anxiety-provoking components of CBT for OCD...

BACKGROUND AND AIMS: Pioglitazone (PIO), a potent agonist of PPAR-gamma, is a promising candidate treatment for cocaine use disorder (CUD). We tested the effects of PIO on targeted mechanisms relevant to CUD: cocaine craving and brain white matter (WM) integrity. Feasibility, medication compliance, and tolerability were evaluated. DESIGN: Two-arm double-blind randomized controlled proof-of-concept pilot trial of PIO or placebo (PLC). SETTING: Single-site outpatient treatment research clinic in Houston, Texas, USA...
