Microscopic photograph of the hippocampus demonstrating the characteristics of Alzheimer's disease which include neuritic plaques (senile plaques) which are extracellular deposits of the amyloid beta-protein (AB). In the more numerous, smaller diffuse plaques this AB alone is present as filamentous masses. However, the diagnostic neuritic plaques also have dystrophic dilated and tortuous neurites, microglia, and surrounding reactive astrocytes. These plaques are best seen with a Bielschowsky (silver) stain.
