[The presence of aluminum in cerebral vessels in Alzheimer's disease].

Abstract

Morin staining is a specific method by which to detect aluminium in the brain. In cases of Alzheimer disease, aluminium was found to occur in neurons and glial cells, dense cores of senile plaques, primitive plaques, and intracortical congophilic vessels. Findings obtained are likely to suggest concomitant presence of aluminium and amyloid. Aluminium is assumed to have high affinity for amyloid. Aluminium is thus capable of overcoming the blood-brain barrier.
