- In the Piteå River Valley all persons with memory impairment that interferes with normal life are referred to one hospital department for clinical workup and diagnosis. 619 patients were assessed in the department during the years 1990–1995. Of these, 36.9% had Alzheimer’s disease (AD), 30.4% had vascular dementia (VaD), 3.0% had a mixed AD/VaD, 3.2% had frontotemporal dementia and 5.3% had other forms of dementia. Another 7% had memory impairment but no dementia. The overall mean annual incidence rate of clinically relevant dementia was 295/100,000 persons at risk and the mean prevalence rate was 755/100,000 persons. For persons 65 years and older the incidence and prevalence rates were 840 and 2,150/100,000 persons, respectively. This means that annually, approximately 300 persons/100,000 population over the age of 40 need medical attention or social services.

- In this study, we determined the relationship between Guillain-Barré syndrome (GBS) and pregnancy. By taking advantage of several nationwide registers and the availability of personal identification numbers, we calculated person-years for Swedish females aged 15-49 years in the following categories: (1) neither pregnant nor postpartum; (2) pregnant; (3) in the first month postpartum, or (4) in the first 3 months postpartum during 1973-1983. For these women, we determined the corresponding exposure status of hospital-registered GBS cases. Medical records were examined for GBS cases hospitalized during the 2-week period postpartum and 1-month period after the last menstruation. Poisson regression analysis yielded age-adjusted relative risks (RRs) of 0.86 (95% CI 0.40-1.84) for pregnant women, and 1.47 (0.54-3.99) and 2.21 (0.55-8.94) for females during the 3-month and the 30-day period after delivery. The risk for GBS seems to be lower during pregnancy and increases after delivery.
