BACKGROUND The neuropeptides leptin and ghrelin are involved in the appetite regulating network consisting of distinct orexigenic (ghrelin) and anorexigenic (leptin) circuitries. Recently, it has been shown that elevated leptin levels are associated with alcohol craving in patients suffering from alcoholism. Therefore, the aim of the present pilot study was(More)
BACKGROUND Alpha synuclein has been found elevated in dopamine neurons of cocaine abusers and in rats whose alcohol preference is inbred. METHODS The alpha synuclein mRNA expression level was measured by quantitative polymerase chain reaction in the blood of 75 male alcoholics and 69 nondrinking healthy control subjects. Alcohol craving was assessed by(More)
BACKGROUND A role of appetite-regulating peptides like leptin and ghrelin in the neurobiology of alcohol craving has been proposed by several studies. Aim of this analysis was to search for differences regarding an association between these peptides and alcohol craving with respect to different subtypes and beverage consumption patterns in patients with(More)
Recent studies have described an association of leptin serum levels and craving in alcohol dependent patients. The aim of the present study was to investigate a large patients' sample using a power-based statistical analysis. We included 156 male and 33 female patients suffering from alcohol dependence admitted for detoxification treatment. Leptin serum(More)
BACKGROUND Alpha synuclein has been found to be increased in dopamine neurones of cocaine abusers and in rats whose alcohol preference is inbred. Furthermore, increased alpha-synuclein messenger RNA expression has been linked to craving in patients with alcoholism. The aim of the current study was to investigate whether protein levels of alpha synuclein in(More)
Gray matter abnormalities have been found in anorexia nervosa (AN) in several brain regions. However, little is known about white matter abnormalities under the condition of AN. To comprehensively assess the microstructural integrity of white matter pathways in women with anorexia nervosa, we performed voxel-based Diffusion Tensor Imaging (DTI). 21 women(More)
OBJECTIVE There is growing evidence, that genetic variants contribute to the pathogenesis of anorexia nervosa and bulimia nervosa. Genetic studies have revealed candidate genes, but no satisfactory associations with the disorders have been found so far. The aim of the present study was to evaluate, whether behavioral and attitudinal traits of the disorders(More)
BACKGROUND As epidemiological surveys have shown, binge drinking is a constant and wide-spread problem behavior in adolescents. It is not rare to find that more than half of all adolescents engage in this behavior when assessing only the last 4 weeks of time independent of the urbanity of the region they live in. There have been several reviews on(More)
Subtyping in alcohol dependence has become an important issue as studies have proposed different neurobiological mechanisms in alcoholism in the recent years. Studies have shown that alcohol dependence reflects a wide range of different phenotypes, including psychological, social, and neurobiological factors. Different ways of subtyping have been proposed(More)
