摘要：

Computerized spectral analysis of the EEG was performed in 119 healthy, elderly men and women, ranging in age from 60 to 87 years with an (x) over bar age of 70.4 years, to evaluate gender-related variance. The groups did not differ in age, education levels or Folstein score. We compared the parasagittal derivations in men (n = 53) to women (n = 66), controlling for the effect of age by decade. Compared to men, women had a significant (usually P < 0.01) increase in the parasagittal mean frequency (1-30 Hz and 4-20 Hz) beta(1) and beta(2), while alpha(2) and theta-beta were decreased. Mean frequency did not differ significantly by decade, nor were there significant sex-age interactions. Our results extend previous EEG spectral findings to older, healthy, elderly subjects. Although the basis for the gender-related differences is uncertain, we suggest that quantitative EEGs establish gender-based norms in elderly adults.
