High prevalence of behavioral and psychiatric disorders in adults with Prader-Willi Syndrome (PWS) has been reported in last few years. However, data are confusing and often contradictory. In this article, we propose a model to achieve a better understanding of the psychopathological features in adults with PWS. The study is based on clinical observations of 150 adult inpatients, males and females. Non-parametric statistics were performed to analyse the association of psychopathological profiles with genotype, gender and age...

Little is known about the neurological control of human sexual behavior. Investigating and measuring this behavior by using quantitative and objective methods is difficult. Insights from lesion studies contribute to analyze the effects of neurological disorders on human sexual behavior. In this chapter, we focus on frontal lobe lesions, brain injuries, epilepsia, dementia, and Parkinson disease to describe human sexual behavior disorders, in order to highlight cortical and subcortical brain regions and neural networks involved in human sexual behavior...

AIMS: The objective of this study is to explore, within a sample of early psychosis patients (EPP), if subgroups regarding rate of violent behaviour (VB) against others can be identified on the basis of dynamic risk factors (treatment modifiable characteristics). METHODS: In a sample of 265 EPP, treated at the Treatment and Early Intervention in Psychosis Program in Lausanne, we conducted a latent-class analysis on the basis of the main dynamic VB risk factors (substance use disorder [SUD], positive symptoms, insight, and impulsivity)...

OBJECTIVE: The goal of this study was to determine the sensitivity and specificity of some widely used, easily administered clinical tests. BACKGROUND: Simple tests of oculomotor function have become widely used for clinical screening of patients suspected of having vestibular disorders despite a paucity of evidence showing good statistical support for their use in this highly variable population. METHODS: Healthy controls with no history of otologic or neurologic disorders (n = 291) were compared to patients with known vestibular disorders (n = 62)...

REVIEW
Andrea Schampel, Stefanie Kuerten
Voltage-gated calcium channels (VGCCs) are widely distributed within the central nervous system (CNS) and presumed to play an important role in the pathophysiology of a broad spectrum of CNS disorders including Alzheimer's and Parkinson's disease as well as multiple sclerosis. Several calcium channel blockers have been in clinical practice for many years so that their toxicity and side effects are well studied. However, these drugs are primarily used for the treatment of cardiovascular diseases and most if not all effects on brain functions are secondary to peripheral effects on blood pressure and circulation...

Voltage-gated sodium (Na(+)) channels are expressed in virtually all electrically excitable tissues and are essential for muscle contraction and the conduction of impulses within the peripheral and central nervous systems. Genetic disorders that disrupt the function of these channels produce an array of Na(+) channelopathies resulting in neuronal impairment, chronic pain, neuromuscular pathologies, and cardiac arrhythmias. Because of their importance to the conduction of electrical signals, Na(+) channels are the target of a wide variety of local anesthetic, antiarrhythmic, anticonvulsant, and antidepressant drugs...

Previous work has suggested that maternal developmental disorder traits related to autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) are significantly associated with child maltreatment. However, there may be other important maternal characteristics that contribute to child maltreatment. We hypothesized that maternal impulse control disability may also affect child maltreatment in addition to maternal developmental disorder traits. We aimed to test this hypothesis via a cohort study performed in Tokyo (n = 1,260)...

AIMS: Chronic metabolic acidosis (CMA) refers to increased plasma acidity due to disturbed acid-base equilibrium in human body. CMA leads to many dysfunctions including disorders of intestinal metabolism and barrier functions. The human body responds to these intestinal dysfunctions by creating a compensatory mechanism at genomic level in intestinal epithelial cells. This study was to identify the molecular pathways involved in metabolic dysfunction and compensatory adaptations in intestinal epithelium during CMA...

Gambling disorder affects approximately 1.1-3.5% of the population, with the rates being higher in young adults. Despite this high prevalence, little is known regarding which pathological gamblers decide to seek treatment. This study sought to examine the differences in three groups of pathological gamblers: those who did not seek treatment (n = 94), those who sought therapy (n = 106) and those who sought medication therapy (n = 680). All subjects were assessed on a variety of measures including demographics, family history, gambling history, comorbid psychiatric disorders and an assortment of clinical variables such as the Quality of Life Inventory, Hamilton Depression and Anxiety Rating Scales, Yale Brown Obsessive Compulsive Scale for Pathologic Gambling (PG-YBOCS), Barratt Impulsiveness Scale, Eysenck Impulsiveness Questionnaire and select cognitive tasks...

Attention deficit disorder (ADD) is characterized by a pattern of inattention and/or impulsivity that is inconsistent with developmental level and interferes with normal functioning in at least two settings. A recent meta-analysis suggested a significant relationship between lead (Pb) exposure and attention deficit symptoms. This study evaluated the potential relationship between increasing blood Pb levels and the risk of a reported ADD diagnosis. This cross-sectional study examined a sample of 2109 persons (32,762,158 weighted-persons) between 10 and 19 years-old from the 2003-2004 National Health and Nutritional Examination Survey (NHANES)...

BACKGROUND: Alcohol-induced disinhibition (AID) is defined as a "loss of restraint over some form of behavior after drinking alcohol regardless of its amount". Although many previous studies have investigated on alcohol use disorder and suicide attempt, few studies have focused on AID and suicide. METHODS: A total of 9461 adults who had a history of drinking completed a face-to-face interview using the Korean version of Composite International Diagnostic Interview (K-CIDI) with the Suicide Module, and Barratt Impulsiveness Scale 11 (BIS-11)...

BACKGROUND: Fibromyalgia syndrome (FMS) is a chronic, generalized and diffuse pain disorder accompanied by other symptoms such as emotional and cognitive deficits. The FMS patients show a high prevalence of gastrointestinal symptoms. Recently it has been found that microbes in the gut may regulate brain processes through the gut-microbiota-brain axis, modulating thus affection, motivation and higher cognitive functions. Therefore, the use of probiotics might be a new treatment that could improve the physical, psychological and cognitive state in FMS; however, no evidence about this issue is available...

Background and aims The DSM-5 includes criteria for diagnosing Internet gaming disorder (IGD) that are adapted from substance abuse and widely used in research and clinical contexts, although evidence supporting their validity remains scarce. This study compared online gamers who do or do not endorse IGD criteria regarding self-control-related abilities (impulsivity, inhibitory control, and decision-making), considered the hallmarks of addictive behaviors. Method A double approach was adopted to distinguish pathological from recreational gamers: The first is the classic DSM-5 approach (≥5 criteria required to endorse the IGD diagnosis), and the second consists in using latent class analysis (LCA) for IGD criteria to distinguish gamers' subgroups...

BACKGROUND: Suicidal behavior accounts for at least 40,000 admissions per year to emergency departments in Japan; however, little is known about emergency admissions owing to suicidal behavior in metropolitan areas. Therefore, we examined the clinical characteristics of suicidal behavior using psychosocial assessments performed by experienced psychiatrists in an intensive care unit. METHODS: Participants were 971 patients admitted to a university hospital's intensive care unit for suicidal behavior between July 2006 and June 2013...

The interest in studying addictive use of online sexual activities (OSA) has grown sharply over the last decade. Despite the burgeoning number of studies conceptualizing the excessive use of OSA as an addictive disorder, few have tested its relations to impulsivity, which is known to constitute a hallmark of addictive behaviors. To address this missing gap in the literature, we tested the relationships between addictive OSA use, impulsivity traits, and affect among a convenience sample of men (N=182; age, M=29...

OBJECTIVES: Kleptomania is characterized by strong urges to steal and is one of only a few psychiatric disorders defined by illegal behaviors, but the clinical characteristics of individuals with kleptomania who have faced legal consequences due to their behavior are poorly understood. METHOD: From 2001 to 2012, we recruited 107 adult participants with DSM-IV kleptomania. Participants with a history of shoplifting-related arrest (N=82) were compared with those who had no such history (N=25) on demographics, clinical features, and a self-report measure of impulsivity...

BACKGROUND: The limited behavioural phenotype literature on Phelan-McDermid syndrome (PMS) indicates atypically high levels of activity, impulsivity and autism spectrum disorder (ASD) behaviours. Divergent profiles of ASD in PMS are also reported, with some studies demonstrating similarities to idiopathic ASD and others indicating an uneven profile of social and communication impairments and repetitive behaviours. An evaluation of the behavioural phenotype of PMS and the prevalence and phenomenology of ASD is warranted, particularly given the causal involvement of the SHANK3 gene in the aetiology of PMS...

BACKGROUND: Highly hypnotizable individuals have impaired executive function, elevated motor impulsivity and increased emotional sensitivity, which are sometimes found in bipolar disorder patients. It is then reasonable to assume that certain aspects of hypnotic susceptibility differ with the types of bipolar disorder. METHODS: The Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) test, the Mood Disorder Questionnaire (MDQ), the Hypomanic Checklist-32 (HCL-32) and the Plutchick-van Praag Depression Inventory (PVP) were applied to 62 patients with bipolar I disorder, 33 bipolar II disorder, and 120 healthy volunteers...

BACKGROUND: Eisenmenger syndrome as a severe form of cyanotic congenital heart disease results in a complex multisystemic disorder. Due to increased systemic venous pressure and the inability to ensure systemic perfusion and metabolic requirements, the liver may develop congestion, fibrosis or cirrhosis. This study aimed to assess hepatic abnormalities in Eisenmenger patients non-invasively. METHODS AND RESULTS: 10 adults with Eisenmenger syndrome (six female; median age 44...
