Relative to bred low-responder (bLR) rats, bred high-responder (bHR) rats have an exaggerated locomotor response to a novel environment, are more risk-taking, more impulsive, and more likely to exhibit compulsive drug-seeking behaviors. These phenotypic differences in addiction-related behaviors and temperament have previously been associated with differences in neurotransmitter signaling, including the mesolimbic dopamine system. In the current study, we applied advanced in vivo microdialysis sampling in the nucleus accumbens of bHRs/bLRs to assess differences in basal and stimulated neurochemical efflux more broadly...

BACKGROUND: Children with autistic spectrum disorder (ASD) frequently present with inattention, impulsivity and hyperactivity, which are the cardinal symptoms of attention deficit hyperactivity disorder (ADHD). The effectiveness of methylphenidate, a commonly used ADHD treatment, is therefore of interest in these children. OBJECTIVES: To assess the effects of methylphenidate for symptoms of ADHD (inattention, impulsivity and hyperactivity) and ASD (impairments in social interaction and communication, and repetitive, restricted or stereotypical behaviours) in children and adolescents aged 6 to 18 years with ASD...

Behaviour may be influenced by pituitary hormones or treatments. Dopamine agonist (DA) indicated in prolactinomas treatment can cause side effects, and especially impulse control disorders. In the context of prolactinomas treatment, impulse control disorders (ICD) have been reported like gambling, compulsive shopping, but mostly hypersexuality. These ICD can occur with low AD doses, and seem to be independent of type of molecule and psychiatric medical history. The main pathophysiologic hypothesis is a dysregulation of dopaminergic pathway involved in reward system...

BACKGROUND: Non suicidal self-injuries (NSSIs) are deliberate self-harm behaviors without suicidal intent, usually starting in adolescence, with increasing rates of occurrence both in epidemiological and clinical samples. Several studies associated cyclothymic-hypersensitive temperament (CHT) with self-harm behaviors and suicidal risk. Aim of this study is to explore the association between NSSIs and CHT in a clinical sample of adolescents. We hypothesized that CHT may differentiate NSSI from non-NSSI adolescents with mood disorders, when other psychopathological features are controlled for...

Psychopathy consists of a constellation of affective-interpersonal features including lack of empathy, callousness, manipulativeness and interpersonal charm, impulsiveness and irresponsibility. Despite its theoretical and predictive value in forensic contexts, the relationships between the psychometric dimensions of psychopathy, including its antisocial features, and the construct's neuropsychological characteristics remain uncertain. In this study, 685 personality-disordered prisoners with histories of serious violent or sexual offenses were assessed for psychopathy before completing a computerized and well-validated assessment of the ability to recognize emotional expressions in the face...

Child-to-parent violence is a form of family violence that is still a well-kept secret. Abused parents can be victims of different types of abuse. Children can use both physical and psychological violence such as financial threats to take control of the home. In this situation, parents often no longer dare to contradict their children by fear of triggering uncontrollable violence. Although the phenomenon recently drew the attention of the media, there is still little knowledge about its prevalence and clinical characteristics...

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...

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)...

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)...

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: 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...

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: 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...

PURPOSE OF REVIEW: Impulsivity is considered a trans-diagnostic feature of many mental disorders, yet our understanding of the concept and approaches to measurement have evolved significantly with advances in neuroimaging. This review will provide an overview of impulsivity as it is currently understood, its association with personality disorder and implications for treatment. RECENT FINDINGS: Impulsivity is now considered to involve failure of inhibitory control, either motor or cognitive, and deficits of the reward valuation system...

Impulse control disorders (ICDs) in Parkinson's disease (PD) are considered dopaminergic treatment side effects. Cognitive and affective factors may increase the risk of ICD in PD. The aim is to investigate risky decision-making and associated cognitive processes in PD patients with ICDs within a four-stage conceptual framework. Relationship between ICDs and affective factors was explored. Thirteen PD patients with ICD (ICD+), 12 PD patients without ICD (ICD-), and 17 healthy controls were recruited. Overall risky decision-making and negative feedback effect were examined with the Balloon Analogue Risk Task (BART)...

High impulsivity and poor executive function are characteristic of methamphetamine use disorder. High arousal in the impulsive system has been proposed to compromise the executive system's regulating ability (i.e. the dual-systems model). While interaction between these variables may partly explain poor treatment outcomes associated with methamphetamine use disorder, previous research has tended to examine each factor separately. We investigated whether high impulsivity (measured with an impulsive choice task) and poor executive function (measured with a working memory task) predict methamphetamine use (determined by hair sample) in the 6 weeks following treatment commencement...

Individuals with a family history of alcohol and other drug use disorders (FH+) are at increased risk for developing substance use disorders themselves relative to those with no such histories (FH-). Here we sought to identify key characteristics associated with FH+ status and alcohol and other drug use disorder status in a large cohort of FH+ and FH- young adults. We conducted principal component analyses on demographic, temperament, and cognitive measures differentiating 506 FH+ and 528 FH- young adults. Three principal components were identified, and these component scores were then used to predict the odds of being FH+ and the odds of having an alcohol or other drug use disorder...

The fundamental diagnoses of attention deficit hyperactivity disorder (ADHD) and autism consists of inattention, hyperactivity, and impulsivity, which lead to abnormal social interactions and repetitive and restricted behavior. Several food contaminants are suspected of being a possible contributing factor to the present-day increase in diseases, such as obesity and ADHD, and pesticides are also considered as a contributor to the increased prevalence of ADHD. Imidacloprid is a neonicotinoid insecticide with lower toxicity to mammals...

Bo Bach, Joan M Farrell
In this study we investigated how early maladaptive schemas and schema modes uniquely characterize Borderline Personality Disorder (BPD) patients versus comparison groups. BPD patients (n = 101) were systematically matched with personality disordered patients without BPD (n = 101) and healthy controls (n = 101). Differences were investigated using one-way ANOVA and multinomial logistic regression analyses. Results indicated that schemas of Mistrust/Abuse and Defectiveness/Shame along with modes of Angry Child, Impulsive Child, and (low) Happy Child uniquely differentiated BPD patients from patients with other personality disorders...
