Abstract This study examines the role of aluminium in the etiology of Alzheimer’s disease (AD). Brains taken at autopsy (n=50) from patients with a history of long-term hemodialysis (HD) and intake of aluminium (Al)-containing drugs were examined by light microscopy. Using our modified silver stain we have been able to demonstrate and clearly discriminate between AD changes and dialysis-associated encephalopathy (DAE) on paraffin sections; evaluation was done with a 3-point scale. DAE morphology is characterized by lysosome-derived intracytoplasmic, Al-containing, pathognomonic, argyrophilic inclusions in choroid plexus epithelia, cortical glia and neurons. A statistically significant difference was found between the amounts of drug-related Al ingested and the degree of DAE-related morphological change (P
