Cerebral Circulatory and Electroencephalographic Changes in Aging and Dementia
A full understanding of senescent behavioral changes requires information from in vivo physiologic studies, including both the electroencephalogram (EEG) and cerebral blood flow (CBF). The purpose of the present paper is to review some of the recent findings on cerebral physiology in the dementias of old age. Earlier EEG and CBF findings have been extensively reviewed elsewhere (Obrist 1972; Obrist 1975) and will only be summarized here.
