The entorhinal cortex (EC) plays a crucial role as a gateway connecting the neocortex and the hippocampal formation. Layer II of the EC gives rise to the perforant pathway, the major source of the excitatory input to the hippocampus, and layer IV receives a major hippocampal efferent projection. The EC is affected severely in Alzheimer disease (AD), likely contributing to memory impairment. We applied stereological principles of neuron counting to determine whether neuronal loss occurs in the EC in the very early stages of AD. We studied 20 individuals who at death had a Clinical Dementia Rating (CDR) score of 0 (cognitively normal), 0.5 (very mild), 1 (mild), or 3 (severe cognitive impairment). Lamina-specific neuronal counts were carried out on sections representing the entire EC. In the cognitively normal (CDR = 0) individuals, there were ~650,000 neurons in layer II, 1 million neurons in layer IV, and 7 million neurons in the entire EC. The number of neurons remained constant between 60 and 90 years of age. The group with the mildest clinically detectable dementia (CDR = 0.5), all of whom had sufficient neurofibrillary tangles (NFTs) and senile plaques for the neuropathological diagnosis of AD, had 32% fewer EC neurons than controls. Decreases in individual lamina were even more dramatic, with the number of neurons in layer II decreasing by 60% and in layer IV by 40% compared with controls. In the severe dementia cases (CDR = 3), the number of neurons in layer II decreased by ~90%, and the number of neurons in layer IV decreased by ~70% compared with controls. Neuronal number in AD was inversely proportional to NFT formation and neuritic plaques, but was not related significantly to diffuse plaques or to total plaques. These results support the conclusion that a marked decrement of layer II neurons distinguishes even very mild AD from nondemented aging.
