OBJECTIVE Citicoline is an endogenous nucleotide that has historically been used to treat stroke, traumatic brain injury, and cognitive dysfunction. Research has also shown that citicoline treatment is associated with improved cognitive performance in substance-abusing populations. We hypothesized that marijuana (MJ) smokers who received citicoline would demonstrate improvement in cognitive per...

Currently prominent models of narcissism (e.g., Morf and Rhodewalt, 2001) primarily explain narcissists' self-defeating behaviors in terms of conscious cognitive and affective processes. We propose that the disposition of impulsivity may also play an important role. We offer 2 forms of evidence. First, we present a meta-analysis demonstrating a strong positive relationship between narcissism an...

We assessed correlates of obsessive-compulsive (OCPD), schizotypal (SPD) and borderline (BPD) personality disorders in 110 obsessive-compulsive disorder (OCD) patients. We found OCD patients with OCPD (20.9%) to exhibit higher rates of hoarding and bipolar disorders, increased severity of hoarding and symmetry, lower prevalence of unacceptable thoughts involving sex and religion and less non-pl...

It is now generally agreed that there are inherent sex differences in healthy individuals across a number of neurobiological domains (including brain structure, neurochemistry, and cognition). Moreover, there is a burgeoning body of evidence highlighting sex differences within neuropsychiatric populations (in terms of the rates of incidence, clinical features/progression, neurobiology and patho...

Problem: Food addiction, which is characterized by poor control of eating and dietary habits, has been linked to aspects of reduced executive functioning, including impulsivity and impaired inhibitory control. Impulsivity and inhibitory control can be measured by subjective self-report inventories and objective, performance-based cognitive tasks. No prior works have examined whether subjective ...

BACKGROUND Impaired decision-making is one diagnostic characteristic of alcoholism. Quantifying decision-making with rapid and robust laboratory-based measures is thus desirable for the testing of novel treatments for alcoholism. Previous research has demonstrated the utility of delay discounting (DD) tasks for quantifying differences in decision-making in substance abusers and normal controls....

OBJECTIVE Poor impulse control is thought to be one of the characteristics of alcohol addiction. The capacity to remain abstinent may be linked to cognitive bias related to three dimensions of impulsivity: motor, non-planning, and attentional impulsivity. The aim of this study was to evaluate the neuropsychological profile related to these impulsivity dimensions in alcohol-dependent patients wi...

Introduction Bipolar disorder (BD) is a chronic mental characterized by mood instability 1 . BD further related to neurocognitive and functional disruptions that remain remarkably stable even when patients are euthymic, leading poor well-being quality of life. Mindfulness means paying attention on purpose, in the present moment, involves different facets such as observing, describing, acting wi...

Evidence for serotonin involvement in impulsivity has generated interest in the measurement of impulsivity in regular ecstasy users, who are thought to display serotonergic dysfunction. However, current findings are inconsistent. Here, we used a recently developed Information Sampling Test to measure ‘reflection’ impulsivity in 46 current ecstasy users, 14 subjects who used ecstasy in the past,...
