ABSTRACT
Though congitive functions of a man decline in normal aging and memory decline is the most common complaint of an elderly, the status of quantitive and qualitative estimates of these are rare in Korea. To assess the qualitative and quantitive aspect of changes of memory in aging, neuropsychological tests about memory functions were performed and the results were.analyzed in healthy adult volunteers of 20 to 9 year-old, having no evidence-of organic brain dysfunction. The scores of each tests.are lower than that of English-speaking countries, but memory functions declined significantly in normal aging and the qualitative aspect of these are characteristics. Contrary to the western reports. The visuospatial memory declined significantly before the age of 50 and the verbal memory after 50 in aging. So we should take care in screening and diagnosis of dementia and amnesia using these neuropsychological test in Korea.
