Argyrophilic grain disease (AGD) constitutes a neurodegenerative disorder that occurs in the brains of the elderly and affects 5% of all patients with dementia. Tau protein-containing lesions known as argyrophilic grains and located predominantly in limbic regions of the brain characterize this disease. Dementia is encountered in only a subset of cases that display the morphological pattern of AGD. Read More

Converging evidence supports the role of oxidative stress in the pathology of Alzheimer's disease (AD). This notion is further supported by recent findings of increased NAD(P)H:quinone oxidodreductase (NQO1) activity, a potent antioxidant system, in association with hippocampal AD pathology. If increased NQO1 activity is truly related to the AD process, however, we would expect to see regional co-localization of NQO1 activity with AD pathology throughout affected brain regions and the absence of NQO1 activity in regions unaffected by AD.

Physical exercise is considered to exert a positive neurophysiological effect that helps to maintain normal brain activity in the elderly. Expectations that it could help to fight Alzheimer's disease (AD) were recently raised. This study analyzed the effects of different patterns of physical exercise on the 3xTg-AD mouse. Read More

The present study is an attempt to reclassify the pathological subtypes of DLB based on both Lewy pathology and Alzheimer pathology, and to clarify the pathological boundary between DLB and Parkinson's disease (PD) or Alzheimer's disease (AD) in autopsied cases, using pathological and immunohistochemical methods. Dementia with Lewy bodies was classified into the limbic type and neocortical type according to the degree of Lewy pathology, including Lewy bodies (LB) and LB-related neurites, by our staging and was classified into the pure form, common form and AD form according to the degree of Alzheimer pathology including NFT and amyloid deposits by Braak staging. These combined subtypes were lined up on a spectrum not only with Lewy pathology but also with other DLB-related pathologies including Alzheimer pathology, neuronal loss in the substantia nigra, spongiform change in the transentorhinal cortex and LB-related neurites in the CA2-3 region.
