Alcohol-associated cues are able to elicit brain activations in mesocorticolimbic networks that are related to the rewarding properties of the drug. Some authors hypothesize that the activation of the mesocorticolimbic reward system triggers an attention allocation to alcohol-associated cues. Yet, no functional magnetic resonance imaging (fMRI) studies(More)
OBJECTIVES The aim of the present study was to investigate beneficial effects of cue exposure treatment for alcohol dependence by contrasting it with a well-established treatment approach. We hypothesized that cue exposure treatment is associated with a stronger decline of craving, a stronger increase in self-efficacy and has beneficial effects on drinking(More)
AIMS In the present study, the effect of previous detoxifications on prefrontal function and decision making was examined in alcohol-dependent patients. Further, we examined whether the length of abstinence affects cognitive function. METHODS Forty-eight alcohol-dependent patients were recruited from an inpatient detoxification treatment facility and(More)
BACKGROUND In alcohol-dependent patients, alcohol-associated cues elicit brain activation in mesocorticolimbic networks involved in relapse mechanisms. Cue-exposure based extinction training (CET) has been shown to be efficacious in the treatment of alcoholism; however, it has remained unexplored whether CET mediates its therapeutic effects via changes of(More)
AIMS Craving for the rewarding effects of alcohol may be evoked by conditioned alcohol-like effects whereas conditioned compensatory responses may induce withdrawal relief craving. We tested the hypothesis that drinking in positive emotional states is associated with appetitive reactions to alcohol-associated cues and contributes to reward craving, while(More)
Recent studies demonstrated that alcohol impairs inhibitory control of behavioural responses. We questioned whether alcohol via its disinhibiting effects would also impair the inhibition of an instrumental avoidance response in the presence of a safety signal. Thirty-six moderate social drinkers were randomly allocated to receiving either alcohol (0.8 g/kg)(More)
Recent models of the development of addiction propose a transition from a pleasure-driven to a heavily automatized behaviour, marked by a loss of cognitive control. This study investigated the deficits in different components of cognitive functions including behavioural inhibition in response to alcohol-related stimuli in alcohol-dependent patients (ADP)(More)
AIMS The aim of this study was to analyse initial orienting processes as well as maintenance of attention towards alcohol cues in recently detoxified alcoholics and light social drinkers. Furthermore, we investigated the influence of pre-treatment alcohol consumption and abstinence duration onto alcohol-related attentional bias. METHODS We used an(More)
BACKGROUND/AIMS Little is known about the association of binge drinking with impulsivity related to trait- or state-like aspects of behavior. The aim of the present study was therefore to investigate whether binge drinkers show an impairment of inhibitory control in comparison to non-binge drinkers when confronted with alcohol-associated or control stimuli,(More)
OBJECTIVE Starting from a model of impaired response inhibition and salience attribution for addictive behaviour we investigated whether obese participants show a greater impairment of inhibitory control in response to food-associated cues compared with neutral stimuli and whether this is seen in normal-weight control subjects. In addition, we questioned(More)
