Deep brain stimulation (DBS) of the subthalamic nucleus markedly improves the motor symptoms of Parkinson's disease, but causes cognitive side effects such as impulsivity. We showed that DBS selectively interferes with the normal ability to slow down when faced with decision conflict. While on DBS, patients actually sped up their decisions under high-conflict conditions. This form of impulsivit...
Initial evidence that cognitive function improves after bariatric surgery exists. The post-surgery increase in cognitive control might correspond with a decrease of impulsive symptoms after surgery. The present study investigated cognitive function and nonfood-related impulsivity in patients with substantial weight loss due to bariatric surgery by using a comparative cross-sectional design. Fif...
Attention deficit hyperactivity disorder (ADHD) is a common neurobehavioural disorder which has been associated with sleep and circadian rhythm disturbances. Numerous studies have linked evening circadian typology with traits and behaviours associated with the disorder, although a precise reason for this relationship has not been clarified. The current study examines ADHD symptoms, impulsivity,...
Objective: This study aimed to compare psychological distress, impulsivity, and type D personality between students with positive and negative attitudes toward addiction. Method: The present study was a causal-comparative design. The statistical population consisted of all undergraduate students of Razi University of Kermanshah in 2017-2018. Among them, 305 students were selected by multi-stage...
Implication for health policy/practice/research/medical education: For risky behaviors and mental disorders. The construct of impulsivity is significantly important in research and clinical fields concerning risky behaviors and some mental disorders. Although, according to DSM and ICD, impulsivity is recognized as a diagnostic criterion for several disorders (1), but the way it influences menta...
BACKGROUND In cross-sectional studies, cocaine users generally display elevated levels of self-reported and cognitive impulsivity. To what extent these impairments are stable v. variable markers of cocaine use disorder, and, thus, are pre-existing or drug-induced, has not yet been systematically investigated. METHOD We conducted a longitudinal study with cocaine users who changed or maintaine...
Impulsivity and compulsivity represent useful conceptualizations that involve dissociable cognitive functions, which are mediated by neuroanatomically and neurochemically distinct components of cortico-subcortical circuitry. The constructs were historically viewed as diametrically opposed, with impulsivity being associated with risk-seeking and compulsivity with harm-avoidance. However, they ar...
Because impulsivity-reflectivity (IR), as measured by the Matching Familiar Figures Test (MFF; Kagan, 1965) and KRISP (Wright, Note 1), is correlated with age and IQ, we sought to determine how much variance in impulsivity-reflectivity is attributable to an impulsivity-reflectivity trait and how much to cognitive development, as measured by mental age (MA). Since the usefulness of measures of i...
