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)
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 D 2-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(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)
Of alcoholic patients who underwent MRI (magnetic resonance imaging) of the brain and neuropsychological tests shortly after discontinuation of heavy drinking, a subgroup underwent repeat MRI scans and neuropsychological assessment one year later. The reduction in drinking habits was associated with cognitive improvement but no significant difference in MRI(More)
The effects of hyperbaric oxygen at a pressure of two atmospheres absolute were studied in a group of patients with chronic progressive multiple sclerosis. A slight but statistically insignificant shortening of the visual evoked potential latencies was seen after treatment with hyperbaric oxygen as compared with placebo treatment. The treatment did not(More)
The etiological characteristics of cerebrovascular disease (CVD) before the age of 55 are reviewed in 399 patients admitted to the Department of Neurology, Karolinska Hospital, Stockholm, from 1973-77. The material was well-defined with regard to subtypes of stroke as well as to the diseased population. The control material consists of 829 males and females(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)
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)
