Effects of Various Stimuli on the Elderly with Dementia

The stimulations of (1) group recreation activity, (2) touching, and (3) ringing a bell are given to demented elderly subjects to learn what kinds of effects are obtained by each stimulation. The following are used in the analysis: HDS-R, GBS scales, blood pressures, pulse rates, neurometry, thermography, inquiries, etc. In addition, the particular personality of the demented elderly is found for personal relations and interests in the externality by carrying out a language association test for the subjects. On the relevance between the language association test and objective indices, statistical treatment is difficult because of the characteristics of the language association test. The demented elderly subjects whose numerical values of the objective indices are good tend to appropriately react to the stimulus word in the language association test, and the validity of the objective indices is confirmed.
