ABSTRACT
A possible link between levels of aluminium in drinking water supplies and the incidence and frequency of Alzheimer's disease, or the onset of early senility, have found some support in Southern Norway. Southern Norway has been divided into five zones according to increasing concentrations of aluminium in lakes, and overall mortality statistics from senile and presenile dementia have been compared between the zones. How acids are being formed in the atmosphere is now much better understood and there is some scientific concensus emerging over the relationship between pollutive emissions and acid deposition. The hypothesis has been tested by use of indicators - both for the intake of aluminium from drinking water (concentration of Al) and for the frequency of Alzheimer's/Alzheimerlike diseases. Alzheimer's/Alzheimerlike diseases can only be diagnosed by use of specific cerebral studies, which only exceptionally are being carried out for people dying with symptoms of the diseases in Norway.
