By increasing population of the aged people, the problem on brain aging and dementia becomes an important target of neuroscience, especially in the Western countries and Japan. Formerly, the brain aging has been thought to be a process of involution. However, in human, the intelligence does not always decline in senescence. Recent idea on the intellectual ability is reverse: it remains well in the healthy aged persons, espe-cially the crystallized intelligence after Cattell (1943). By the study with PET, it is known that the utilization of glucose in the brain did not significantly decrease with age.

We presented here the macroscopical and histo-logical changes of the aged human brain firstly, the regenerative capacity of the cultured aged neurons secondly, and the pathological changes of the brain from senile dementia of Alzheimer's type thirdly.
