Abstract

Little attention has been paid to the morphological changes in the olfactory bulbs in patients with dementia of the Alzheimer type, despite the fact that rhinencephalo-limbic structures, which receive fibers directly from the olfactory bulbs, are known to be severely affected.1–4 Recently, Pearson et al.4 raised the possibility that the olfactory tracts provide a portal of entry to the brain for any putative pathogenic agent(s) that induces senile plaque formation and/or Alzheimer’s neurofibrillary tangles (NFT).
