Introduction: Drug craving could be described as a motivational state which drives drug dependents towards drug seeking and use. Different types of self-reports such as craving feeling, desire and intention, wanting and need, imagery of use, and negative affect have been attributed to this motivational state. By using subjective self-reports for different correlates of drug craving along ...

Internet gaming disorder (IGD) is characterized by high levels of craving for online gaming and related cues. Since addiction-related cues can evoke increased activation in brain areas involved in motivational and reward processing and may engender gaming behaviors or trigger relapse, ameliorating cue-induced craving may be a promising target for interventions for IGD. This study compared neura...

Bupropion has been used in the treatment of patients with substance dependence based on its weak inhibition of dopamine and norepinephrine reuptake. We hypothesized that 6 weeks of bupropion sustained release (SR) treatment would decrease craving for Internet game play as well as video game cue-induced brain activity in patients with Internet video game addiction (IAG). Eleven subjects who met ...

OBJECTIVE Since signals for cocaine induce limbic brain activation in animals and cocaine craving in humans, the objective of this study was to test whether limbic activation occurs during cue-induced craving in humans. METHOD Using positron emission tomography, the researchers measured relative regional cerebral blood flow (CBF) in limbic and comparison brain regions of 14 detoxified male co...

BACKGROUND Several theories of cigarette craving suggest that dopaminergic function in the ventral striatum plays an important role. The objective of this study was to determine correlations between craving-related brain activation and dopamine D1 receptor (D1R) binding in smokers. METHODS Twelve smokers and 12 nonsmoking controls underwent [(15)O]H(2)O-positron emission tomography activation...

Cues previously paired with rewarding stimuli induce a time-dependent increase in the motivational craving state (incubation of craving). Whether there is an increase in craving for high-fat (HF) food over time, which may contribute to overeating and obesity, has not been determined. We hypothesized that cues paired with HF pellets would elicit a greater incubation of craving effect than those ...

Craving is what makes addiction to drugs so difficult to overcome. The intense craving that follows a cue that has been previously associated with the drug, combined with a stressful state or a dysphoric state, represents an unstoppable force that leads to drug intake and relapse for most addicted individuals. However, although difficult, some people successfully control this craving, but the b...

BACKGROUND Leptin has been shown to regulate food intake and energy expenditure. Because leptin acts via regulation of appetite, we studied the hypothesis that suggests leptin modulates craving for alcohol as well. METHODS We studied leptin plasma concentrations (RIA) both in alcoholic subjects during inpatient detoxification (day 1: n = 78, day 14: n = 60) and in healthy control subjects (n ...

objective: drug craving is defined as an urge to continue substance abuse. drug dependents use different terms to express their subjective feeling of craving. this study was an attempt to generate an understanding of craving terminology among different groups of persian speaking iranian opiate dependents. method: terms used for the meaning of drug craving were listed by 36 ex-opiate dependents ...
