We have studied local irregularity of brain waves using "local fractal dimensions(LFDs)" for two groups of elderly people, one healthy and the other affected by senile dementia. It is determined that(a) the probability distribution of the LFDs for both groups is subject to the universal law of the beta distribution;(b) the stochastic processes of LFDs of the two groups show a marked difference. We have demonstrated the applicability of the present statistical method based on the LFD for estimating the degree of progression of dementia.
