Abstract
Determining brain lesions by quantified electroencephalography is effected by obtaining absolute power data in a primary frequency domain for a brain region. Power data in the primary frequency domain in relation to power in a secondary frequency domain is determined. The two sets of data are related to obtain a value representative of the electrical output in the brain region. The representative value is compared to a selected base value and quantified departures are mapped topographically. This map is used to identify and assess lesions associated with disorders and afflictions including dementia and demyelinating diseases.
