A putatively functional tetranucleotide repeat polymorphism in the tyrosine hydroxylase gene (TH) has been investigated with regard to different aspects of psychopathology. We investigated whether reported associations of this TH polymorphism may reflect associations with common personality traits. Personality was assessed by the NEO Personality(More)
100 consecutive cases of spontaneous intracerebral haematomas are reported, all examined by computerized tomography (CT). Exact siting of the haemorrhages was obtained, their expansion and volumes were calculated. 36 patients were operated upon. 63 survivors were followed up in respect of disablement and social rehabilitation. Almost half of the haematomas(More)
Drug abuse is associated with a variety of neurological complications. The use of certain recreational drugs shows a marked temporal association with the onset of both haemorrhagic and ischaemic strokes, the majority of which develop within minutes to 1 h after the administration of the index drug. Delayed onset of stroke has also been observed. Acute,(More)
Alterations in the dopamine system have been hypothesized as a predisposing factor in alcoholism. The presence of the TaqI A1 and B1 alleles adjacent to the dopamine D2-receptor gene (DRD2) was studied in Scandinavian alcoholic inpatients (n=74), alcoholics autopsied at a forensic clinic (n=19) and controls (n=81). There were no significant differences(More)
Benzodiazepine (BZ) receptor binding in the brain was determined in five chronic alcohol-dependent men and in five healthy male control subjects using [11C]flumazenil (Ro 15-1788) and positron emission tomography (PET). Magnetic resonance imaging was used to evaluate brain anatomy and pathology, and to define regions of interest in the brain.(More)
Associations of polymorphic genetic markers at the tyrosine hydroxylase (TH) and dopamine D4 receptor (DRD4) loci were examined in Scandinavian chronic alcoholics (n = 72) and control subjects (n = 67). Patients were divided into subgroups with regard to the presence of parental alcoholism and age of onset. Neither the TH nor the DRD4 allele distributions(More)

Alcohol consumption in excess affects the brain negatively, both immediately and in the long-term. Brain lesions in alcohol abusers are multiple and are multifactorial in origin. The toxic effect of ethanol, withdrawal from alcohol, nutritional deficits, and electrolyte disturbances, as well as liver damage, may contribute to the ethiopathogenesis of brain(More)
1. The disposition kinetics of ethanol and its toxic metabolite acetaldehyde were investigated in 10 healthy male volunteers who ingested 0.25 g kg-1 ethanol after an overnight fast. This dose of ethanol was given 2 h after they swallowed a tablet of either calcium carbimide CC (50 mg), a potent inhibitor of low Km aldehyde dehydrogenase (ALDH), or placebo(More)
Numerous studies on the involvement of dopamine receptors in the genetics of alcoholism focused on associations between a polymorphism of the D2 dopamine receptor (DRD2) gene and alcohol dependence. However, the results of these studies are conflicting. Another receptor, the D3 dopamine receptor (DRD3), may be of additional interest since it is specifically(More)
Two regions of the human prodynorphin gene, the exon 4-region coding for the opioid peptides and the putative promotor/exon 1-region were analyzed for possible presence of polymorphisms. No polymorphism was detected in the exon 4-region, whereas a GC/AT base-pair exchange was observed 301 base pairs upstream of the exon 1/intron A boundary. This polymorphic(More)
