Abstract

The distribution of neurofibrillary tangles and senile plaques was surveyed in the striatum of Alzheimer's disease cases. Neurofibrillary tangles were present throughout the striatum, but displayerd significantly higher densities in the nucleus accumbens, olfactory tubercle and tail of the caudate nucleus. Senile plaques with dense amyloid cores showed a similar pattern of distribution. By contrast, non-cored senile plaques were homogenously distributed in all striatal territories. No tangles and few plaques were observed in the striatum of control cases. These findings suggest that the 'limbic' striatum is preferentially vulnerable to pathology in Alzheimer's disease.
