The concept of vascular dementia is not still established. Its pathogenesis is not completely understood, either. It may be different among the subtypes, e.g., ischemic, hemorrhaginc, or Binswanger's disease. In this article epidemiology of vascular dementia was reviewed, based on the important findings regarding to prevalence, ethnic difference in prevalence, incidence, risk factors, and natural history and survival. We have to wait for more elegant concept of and better understanding of vascular dementia.

OBJECTIVE: Examination of the changing pattern of cognitive function in old age. METHOD: Cross-sectional observation of MMSEK performances of the elderly living in a rural community. The mean and standard deviation, coefficient of variability, and 95% confidence interval and difference between the upper and lower limits by the 5-year age interval were employed as indicators of the change. RESULTS: Characteristics of the change of the MMSEK score by age were (1) overall decline and (2) widening of variance in terms of the standard deviation, coefficient of variability and difference between upper and lower limits of the 95% confidence interval. CONCLUSION: The changing pattern of cognitive function with age in the elderly is decline with 'fan-spread' shape. Heterogeneity, genetic effect on cognitive function in the old age, cerebral reserve gained before the old age, and different extent of physical activities might suggest some explanation for the phenomena.

OBJECTIVES: To examine the changing pattern of cognitive function in old age. METHODS: Longitudinal observation of MMSEK performances of the elderly living in a rural community through 2 consecutive 6-year follow-ups. The mean, standard deviation, and coefficient of variability of the three consecutive MMSEK performances with 6-year interval were indicators of the changing pattern. Paired t-test was used for comparison of two consecutive MMSEK performances : MMSEK-90 vs MMSEK-96 and MMSEK-96 vs MMSEK-02, while Student's t-test for comparison between the first and second 6-year changes of the MMSEK performance. RESULTS: In all age groups, the MMSEK performance declined significantly during the two consecutive 6-year periods, the standard deviation and coefficient of variability widened with age, and the second 6-year decline of the MMSEK performance was significantly greater than the first 6-year decline. CONCLUSION: Decline of the cognitive function is steeper in the elderly with age and the declining pattern is the 'fan-spread' shape.
