Marked neuron loss in the predominantly serotonergic nucleus raphes dorsalis (NRd) in Alzheimer's disease (AD) has repeatedly been reported in the literature. However, most of these studies quantitated only part of the NRd and data were expressed as numerical density. Applying a 3-dimensional sampling scheme throughout the entire rostrocaudal extent of the NRd and sampling neurons regardless of their size and staining characteristics, an overall neuron loss of 39.4% was demonstrated and a tendency for cell shrinkage was likely to be present. No rostrocaudal gradient in neuron loss could be shown. These NRd data are in accordance with neuron loss in other subcortical structures in AD.

D003704 Dementia An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness.
