We investigated the survival of patients with amyotrophic lateral sclerosis (ALS) in a follow-up study of all patients hospitalized with the disease in 2 Danish counties during the period 1974 to 1986. There were 186 patients, with a mean age at diagnosis of 64.3 years. The median survival time was 12 months from diagnosis, the 3-year survival rate was 12%,(More)
Acetazolamide increases cerebral blood flow. The generalized and regional changes in blood flow after administration of acetazolamide were evaluated by the xenon-133 inhalation technique in a series of patients with subacute or chronic focal cerebral ischemia. Acetazolamide augmented interhemispheric asymmetry of cerebral blood flow in patients with(More)
OBJECTIVES To study mortality and survival of patients with myasthenia gravis. METHODS 290 patients with myasthenia gravis were studied, including 212 incident cases identified during a comprehensive epidemiological study of myasthenia gravis in western Denmark 1975-89. Follow up was performed on 31 December 1994. Survival curves were constructed using(More)
During a comprehensive epidemiological study of myasthenia gravis (MG) in Western Denmark 1975-1989, we analyzed the occurrence, clinical characteristics and prognosis of associated autoimmune diseases (AAD) in MG patients. AAD were found in 20 of 212 incident cases (9%) and in 30 of 220 prevalent cases (14%). The most common diseases were: thyroid(More)
The two-dimensional xenon-133 inhalation method was used to measure cortical blood flow in 16 patients with small subcortical ischemic infarcts and in 10 patients with larger cortical infarcts in the chronic phase of stroke. An abnormal hemispheric asymmetry of blood flow was seen, not only in patients with cortical infarcts, but also in those with(More)
We studied the epidemiology of myasthenia gravis (MG) in western Denmark from 1975 to 1989, basing case identification on records from all hospitals in the survey area. The population surveyed was 2.80 million in 1985. The average annual incidence rate was 5.0 per million population (women, 5.9; men, 4.2). The point-prevalence rate (January 1, 1990) was 78(More)
Thirty-three patients with reversible ischemic deficits or completed minor strokes had their cerebral function measured neuropsychologically a few days before and 3 months after extra-intra cranial bypass surgery. Three months post-operatively bypass patency was demonstrated by angiography. Ten patients were operated on the right side and 23 on the left(More)
A neuropsychological study of 12 patients with transient ischemic attacks from the carotid artery territory was carried out about 2 months following their latest attack, about a week before STA/MCA bypass operation, and again 3 months postoperatively. The results suggest that the TIA patients as a group were slightly intellectually impaired preoperatively.(More)
A total of 186 cases of motor neuron disease (MND) was identified in two Danish counties during the period 1974-1986. The average annual incidence rate was 1.4/100,000 population, and the male:female ratio of incidence rates was 1.5. Mean age at diagnosis was 64.3 +/- 10.0 years. The incidence rates increased significantly with advancing age and reached a(More)
