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)
Overeating, weight gain and obesity are considered as a major health problem in Western societies. At present, an impairment of response inhibition and a biased salience attribution to food-associated stimuli are considered as important factors associated with weight gain. However, recent findings suggest that the association between an impaired response(More)
Preclinical and clinical data suggest modulating effects of appetite-regulating hormones and stress perception on food intake. Nicotine intake also interferes with regulation of body weight. Especially following smoking cessation gaining weight is a common but only partially understood consequence. The aim of this study was to examine the interaction(More)
CONTEXT Overlapping neurobiological pathways between obesity and addiction disorders are currently in discussion. Whereas the hypothalamic regulation of energy homeostasis by endocrine feedback signals has been widely investigated, its interplay with mesolimbic reward-associated pathways represents a rich field of future research. OBJECTIVE To assess(More)
BACKGROUND Despite the dissemination of second generation antipsychotics for schizophrenia and bipolar disorder, outcomes remain suboptimal, largely due to poor treatment and drug adherence. The primary aim of the current study was to assess the tolerability, validity and feasibility of the pocket-sized electronic diary Medicus®. SUBJECTS AND METHODS Our(More)
BACKGROUND This study examined functional social support (FSS) and its impact on treatment outcome in alcohol-dependent outpatients treated with supervised disulfiram. METHOD FSS was assessed cross-sectionally in 46 severe alcohol-dependent patients participating in a close-meshed biopsychosocial treatment program. The FSS was measured with the Medical(More)
It has been shown that supervised pharmacological relapse prevention with the acetaldehyde dehydrogenase inhibitor disulfiram is effective in alcohol-dependent patients. However, there are numerous serious risks associated with disulfiram. Thus, for individualized treatment monitoring, it would be important to identify those patients before treatment who(More)
Pregabalin is a novel GABA-analogue approved for the treatment of partial onset seizures, neuropathic pain, and general anxiety disorder. Pregabalin has been classified as a Schedule V drug with a low risk of inflicting abuse or addiction. However, some publications have indicated that pregabalin may have a potential for abuse among patients with past or(More)
Chronic alcohol abuse and dependence are associated with dysfunctional dopaminergic neurotransmission in mesocorticolimbic circuits. Genetic and environmental factors have been shown to modulate susceptibility to alcohol dependence, and both may act through epigenetic mechanisms that can modulate gene expression, e.g. DNA methylation at CpG sites.
