[33] During normal aging, oxidative DNA damage in the brain accumulates in the promoters of genes involved in learning and memory, as well as in genes involved in neuronal survival. [34]
In contrast, younger people with normal memory have virtually no orientation problems" [53] (p. 505). So although current research suggests that normal aging is not usually associated with significant declines in orientation, mild difficulties may be a part of normal aging and not necessarily a sign of a particular pathology.

The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory connections become blocked, memory functions decrease much more than what is normal for that age and a memory disorder is ...
