OBJECTIVE Major depression is a major risk factor for suicide. However, not all individuals with major depression commit suicide. Impulsive and aggressive behaviors have been proposed as risk factors for suicide, but it remains unclear whether their effect on the risk of suicide is at least partly explained by axis I disorders commonly associated with suicide, such as major depression. With a c...

BACKGROUND The relationship between impulsivity and suicide has been conceptualized in the literature as a direct one. In contrast, Joiner's [Joiner, T.E., 2005. Why people die by suicide. Harvard University Press, Cambridge, MA.] theory posits that this relationship is indirect in that impulsive individuals are more likely to engage in suicidal behavior because impulsivity makes one more likel...

Background Opiate addiction is associated with complex cognitive impairment, which contributes to the development of compulsive drug use and relapses. Dopamine and N-methyl-D-aspartate receptors play critical roles in opiate-induced cognitive deficits. However, the roles of D1 and D3 receptors in the N-methyl-D-aspartate/glycineB receptor-regulated cognitive behaviors induced by morphine remain...

Previous research suggests an association between hyperactivity-impulsivity - one of the two behavioral dimensions that form attention deficit hyperactivity disorder - and the temperament characteristic of novelty seeking. We aimed to examine etiological links underlying the co-occurrence between these behaviors using a general population sample of 668 twin pairs, ages 7-10, for whom we obtaine...

OBJECTIVE Studies in Western world patients suggest the possible existence of a subgroup of patients with bulimia nervosa (BN) who display multiple problems with impulsivity, such as suicidal attempts. We assessed impulsive behaviors among BN patients in Japan to discuss them crossculturally. METHOD Impulsive behaviors in 64 BN patients were assessed and multi-impulsivity (MI) was defined acc...

The way emotions are regulated might affect the engagement on risk behaviors in adolescents and young adults. Therefore, studying the relationship between these variables could be of great importance. Some of the less studied risky behaviors are pathological gambling, and Internet and videogame abuse. This research aims to analyze the existing relationship between such risky behaviors, emotion ...

Impulsivity is a central defining feature of several psychiatric disorders and a frequent correlate of many forms of psychopathology and maladjustment. Despite recognition of the importance of impulsivity to an understanding of a wide variety of clinically–relevant behaviors, this multifaceted construct remains ill–defined and not well understood. The primary aims of this article are to briefly...

Impulsive and aggressive behaviors are important clinical challenges in the treatment of patients with schizophrenia. They occur both in the acute phase as well as in the chronic phase of the disorder and call for differentiated treatment interventions. It is important to always first consider behavioral and nonpharmacological interventions. High levels of structure and organization together wi...

BACKGROUND Impulsive and compulsive behaviors (ICBs) are a heterogeneous group of conditions that may be caused by long-term dopaminergic replacement therapy (DRT) of Parkinson's disease (PD). The spectrum of ICBs includes dopamine dysregulation syndrome (DDS), punding, and impulse control disorders (ICDs). CONTENTS We made a detailed review regarding the epidemiology, pathology, clinical cha...

Aim To investigate impulsive behaviors in pathological buying (PB). Methods The study included three groups matched for age and gender: treatment seeking outpatients with PB (PB+), treatment seeking psychiatric inpatients without PB (PB-), and a healthy control group (HC). PB was assessed by means of the Compulsive Buying Scale and by the impulse control disorder (ICD) module of the research ve...
