Although the literature contains many references on the electroencephalogram (EEG) of aged psychiatric patients, there are relatively few investigations of brain wave patterns in "normal" senescence. Most of the reports are based on average people with the usual chronic diseases of old age. In contrast, the present project was designed to observe optimally healthy old people and to compare them with elderly subjects who are less healthy. Information could thus be gained on the degree to which factors of health contribute to EEG changes in later life. This phase of the study is reported in the current chapter. The interdisciplinary aspect of the investigation made it possible to pose several additional questions. Of particular interest was the correlation of senescent EEG changes with alterations in cerebral metabolism. It also seemed desirable to determine the relation of EEG findings to early signs of mental deterioration. Results from the interdisciplinary studies are presented in chapter 15. The literature and hypotheses relevant to these issues are reviewed in the following sections. (PsycINFO Database Record (c) 2017 APA, all rights reserved)
