Aging is associated with a lineage in cognitive performance, and is the biggest risk factor for the ripening of Alzheimers unsoundness (AD), although the underlying basis for two of these observations is poorly de?ned. both normal aging and AD are associated with overlapping and increase levels of patholog y. Numerous reports have now linked elevations in pathology as capability mediators of cognitive decline in the elderly, with most studies deoxidise on the role of AD-related pathology.

However, it is important to point out that there are numerous other pathological features observed in the aging brain including corpora amylacea, argyrophilic grains, neuromelanin, and lipofuscin. In this review, I discuss the decreased cognitive performance observed during normal aging, the potential for pathology to transmogrify neuronal function and neuronal viability during normal brain aging, and the potential for common pathologies to either inhibit or promote the! instruction of age-related disorders such as AD. # 2005 Elsevier Ireland Ltd.
