Epidemiologic studies in the general population and those based on the clinical assessment of schizophrenic populations have revealed a high degree of overlap between schizophrenia and addictive disorders. The abuse of psychoactive substances (including alcohol) throughout life is so frequent (50%) that the possibility of a specific link inevitably arises.(More)
BACKGROUND Dysfunction of serotoninergic transmission could predispose to excessive alcohol consumption and dependence. The functional polymorphism of the serotonin transporter gene (5-HTTLPR) has been associated with different disorders, including alcoholism. Considering the likelihood of heterogeneity in the "alcohol dependence" phenotype, 5-HTTLPR may be(More)
The gene coding for the dopamine receptor D3 (DRD3) is considered as a major candidate gene in various addictive disorders. Association studies in alcohol-dependence for this gene are nevertheless controversial. We made the hypothesis that phenotypical heterogeneity of alcohol-dependence (i.e. the DRD3 gene is a vulnerability gene in a specific subgroup of(More)
Because pharmacological and genetic data supported the idea that serotonin receptors of the 5-HT(1B) type can play a modulatory role in alcohol consumption in both human and rodents, the 5-HT(1B) receptor gene is considered as a candidate gene for alcohol dependence. However, contradictory results have been reported as a positive association between alcohol(More)
BACKGROUND The dopamine transporter (DAT) plays a key role in homeostatic regulation of dopaminergic neurotransmission and could thus be involved in the variability of two severe alcohol-withdrawal symptoms, alcohol-withdrawal seizure (AWS) and delirium tremens (DT). Interestingly, an association was found between the DAT gene (9-copy repeat) and the risk(More)
We analysed the impact of the TaqI A1 allele of the D2 dopamine receptor gene on the risk for alcoholism, trying to depict three explanations frequently proposed to explain discrepancies in association and linkage studies: that the A1 allele may act as a marker rather than as a vulnerability factor, that stratification biases and unevaluated controls may(More)
Alcohol-dependence is a complex phenotype, with behavioral, psychological, pharmacological, medical and social dimensions. Aggregation studies, adoption and twin researches have demonstrated that the vulnerability to alcohol-dependence is at least in part linked to genetic factors, the genetic vulnerability to alcoholism being mainly not substance-specific.(More)
The present study investigated the onset of maternal nest building in pregnant Fischer rats following chronic repeated cocaine administration. Pregnant Fischer rats were injected with saline or cocaine, 15 mg/kg, three times daily at 1-h intervals for 10 days starting on gestation day 8. Cocaine-exposed females incorporated less material into their nests(More)
OBJECTIVES Brief interventions are effective in reducing heavy drinking in the general population but few studies examined whether it is also effective in alcohol dependent patients, and whether brief intervention increases self-efficacy. METHOD One hundred and seven patients with alcohol-dependence were randomized in a controlled trial examining the(More)
