Teenagers are often impulsive. In some cases this is a phase of normal development; in other cases impulsivity contributes to criminal behavior. Using functional magnetic resonance imaging, we examined resting-state functional connectivity among brain systems and behavioral measures of impulsivity in 107 juveniles incarcerated in a high-security facility. In less-impulsive juveniles and normal ...

AIM Although the precise nature of pathological gambling (PG) is still elusive, currently it is considered an impulse-control disorder that shares several features with substance dependence, such as deficit in self-regulation and impaired impulsivity. The aim of this study was to evaluate the impulsivity of PG patients by means of the Barratt Impulsivity Scale, version 11 (BIS-11), as compared ...

obsessive-compulsive disorder is characterized by the presence of recurrent and persistent thoughts, urges or images as well as repetitive behaviors or mental acts. according to the existing evidence, it can be predicted that difficulties in emotion regulation, impulsivity and anger are related to obsessive-compulsive disorder in one way or another. the aim of the present study was to predict o...

BACKGROUND Impulsivity has been associated with serotonergic system functions. However, few researchers have investigated the relationship between a polymorphism in the promoter of the serotonin transporter gene (5-HTTLPR) and the different components of impulsivity in a non-clinical population. The aim of this study was to investigate the relationship between a polymorphism in the promoter reg...

Background Impulsivity and reward expectancy are commonly interrelated. Waiting impulsivity, measured using the rodent 5-Choice Serial Reaction Time task, predicts compulsive cocaine seeking and sign (or cue) tracking. Here, we assess human waiting impulsivity using a novel translational task, the 4-Choice Serial Reaction Time task, and the relationship with reward cues. Methods Healthy volun...

purpose and background: eating disorders and obsessive-compulsive disorder co-occur on many occasions. impulsivity is one of the prevalent features between the mentioned disorders. the purpose of this study is to compare the feature of impulsivity and its components in eating disorders, obsessive-compulsive disorder and the normal individuals. methods and materials: this study carried on patien...

OBJECTIVE The aim of the present study was to evaluate relationship of probable attention deficit hyperactivity disorder (ADHD) with severity of psychopathology and the effect of impulsivity on this relationship in a sample of male patients with opioid use disorder (OUD). METHODS Participants included 234 patients (115 inpatients and 119 outpatients) with OUD. Participants were evaluated with...

OBJECTIVE We investigated relationships among gender, impulsivity and disordered eating in healthy college students. METHOD Participants (N=1223) were healthy, undergraduate men (28.5%) and women (71.5%), who completed the Barratt Impulsiveness Scale - Version 11 (BIS-11) and a four-factor version of the Eating Attitudes Test (EAT-16). RESULTS As predicted, mean scores on all four EAT-16 fa...

BACKGROUND Pathological forms of impulsivity are manifest in a number of psychiatric disorders listed in DSM-5, including attention-deficit/hyperactivity disorder and substance use disorder. However, the molecular and cellular substrates of impulsivity are poorly understood. Here, we investigated a specific form of motor impulsivity in rats, namely premature responding, on a five-choice serial ...
