Occurrence of neuropil threads in the senile human brain and in Alzheimer's disease: a third location of paired helical filaments outside of neurofibrillary tangles and neuritic plaques.

Abstract

Paired helical filaments, pathologically changed components of the cytoskeleton of human nerve cells, are demonstrated by a specific silver staining technique, immunostaining and electron microscopy. Accumulations of these filaments are found in the telencephalic cortex of old-aged individuals and patients suffering from Alzheimer's disease. Apart from neurofibrillary tangles and neuritic plaques, paired helical filaments are encountered in neuropil threads. At this third location, pathological filaments occur in small and inconspicuous profiles scattered throughout both allocortical and isocortical areas. The pattern of distribution and packing density of neuropil threads varies between different cortical areas and layers.
