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: Exploration of the questionable Alzheimer disease is important for accurate estimation of prevalence and incidence, understanding the natural history, and evaluation of treatment strategies for the Alzheimer disease. Subjects and METHODS: We compared neuropsychological test performances among 14 nondemented controls, 14 elderly persons with questionable dementia of the Alzheimer type and 14 elderly persons with mild dementia of the Alzheimer type. The test performances analyzed were the digit span of the Korean Adult Wechsler Intelligence Scale, registration, short term memory and long term memory of the Cognitive Impairment Diagnosing Instrument, and paired association learning and logical memory of the Wechsler Memory Scale. RESULTS: There was significant difference between questionable dementia of the Alzheimer type and controls in the long-term memory, short-term memory, immediate and delayed recalls of the logical memory, and easy association. But the subjects with questionable and mild dementia of the Alzheimer type scored similarly on all tests except the long-term memory. CONCLUSION: These findings suggest that questionable Alzheimer disease may be the very early Alzheimer disease.

Most of the research activities on dementias have been and are focused on Alzheimer's disease. With regard to the treatment possibility and the cause and pathogenesis of cognitive impairment, however, non-Alzheimer dementias are also very important. We should extend our efforts to other dementing diseases than Alzheimer's disease.

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.
