Abstract

There are no previous studies which have compared quantitative electroencephalographic (QEEG) activity in young adult and normal elderly participants during olfactory tasks. This may be important if QEEG is to have a role in distinguishing between normal and pathological aging associated with this sensory system. Seventeen healthy elderly subjects (mean age 79.00+/-3.54 years) and 16 young adult controls (mean age 22.60+/-2.00 years) participated in the study. As reported in previous studies, beta1 and 2 activity was significantly greater in elderly subjects compared to young adults, thus confirming the reliability and validity of this study's quantitative electroencephalographic (QEEG) meth..
