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. Mapping is used to determine activation during tasks such as motor and memory tasks, cognitive processing or other conditions, and also to assess the level of perfusion of the brain.
