“…The amount of alpha waves has been reported by many authors to decrease in elderly people, or in cases of dementia (Mundy-Castle et al, 1954;Mankowski & Belonog, 1971), but we reported in a cross-sectional study (Miyasaka et al, 1978) that the percent time alpha did not decrease in the elderly until mental deterioration had advanced. Our finding in the present study of the preservation of percent time alpha until the early eighties is consistent with a cross-sectional study of Matejeck (1980) and with our previous study.…”

“…No longitudinal study of BGT in elderly people has been found in the literature. -Castle et al, 1954;Obrist, 1954;Yamauchi, 1960;Obrist & Busse, 1965;Mankowski & Belonog, 1971;Ohtomo, 1971;Kiloh et al,1981) have reported that slowing of alpha waves was one of the most pronounced characteristics of the EEG of elderly people, and that dominant frequency of alpha waves became slower with increasing age and advancing of dementia. But it is uncertain whether the decrease of alpha frequency progresses linearly through senescence in the normal elderly.…”

“…Previous authors (Gibbs & Gibbs,l951;Mundy-Castle, 1951;Obrist, 1954;Yamauchi, 1960) have found that the amount of fast waves was higher in elderly people than in younger adults. On the other hand, it has been said that fast waves were rare in cases of advanced dementia (Mundy-Castle et al, 1954;Obrist & Henry, 1958;Ohtomo, 1968). But previous authors (Silverman et al, 1955;Ohtomo, 1968;Wang & Busse, 1969) have not always agreed on how the amount of fast waves changed through senescence.…”

Computer-analyzed EEG data and mental functions of the healthy aged (28 survivors and 20 nonsurvivors) were followed for nine years in a study of their relationship with age and longevity. The study revealed that decrease in fast waves occurred from early senescence. The slowing of EEG, the increase in theta waves, and the decrease in alpha frequency became obvious in late senescence, after the late 70s or beyond 80 years. The amount of alpha waves was maintained until the early 80s. The decline of mental functions occurred with the slowing of EEG in late senescence. The slowing of EEG and the lowered scores of psychometrics were closely related to the longevity of life, comparing the survivors and nonsurvivors in retrospect.

“…Electroencephalography was used to study the developing brain of the intact prenatal human fetus (30,37), the developing heart in the intact prenatal human fetus (29,72), the normal aged adult (245,281), brain phenomena in senile psychoses (235), and in retrolental fibroplasia (169). Blum (34) checked on the reliability of electroencephalographic judgments by having 10 sets of electroencephalographic records evaluated by five experienced neurologists.…”

“…Results of many studies suggest that the amount of EEG slow-wave activity is proportional to the degree of mental deterioration in patients with dementia [4][5][6][7][8][9][10]. Therefore, a parallelism between the development of dementia and a successive deterioration of the EEG would be expected.…”

EEG slow-wave activity was correlated with the regional brain syndrome profile in 74 patients with dementia. The EEGs were visually assessed using a semiquantitative rating scale. The intensities of four regional brain syndromes (parietal, frontal, subcortical, global) and the degree of dementia were rated. The patients were examined twice with a 1-year interval. A significant relationship was found between the increase in EEG slow-wave activity and the increase in intensity of the parietal brain syndrome. A somewhat lower significance was found for the relation between increase in slow-wave activity and increase in dementia degree. The results suggest that the EEG deterioration in dementia mainly reflects the gradual decline of parietal brain function.
