The Brain Performance Index for NeuroGuide Deluxe
The Brain Performance Index(BPI) is an estimate of the efficiency of neural resource allocation. It is not designed to replace neuropsychological test, but rather to compliment neuropsychological evaluations, especially where a patient has problems taking a conventional neuropsychological test, or when one wants to rapidly repeat the test.
The Weschler Intelligence test, and the EEG was recorded from 19 channels with a linked ears reference in the eyes closed condition from 339 normal control subjects, age 6 to 18 years of age. EEG variables that correlated at P<.01 were entered into a multivariate regression analysis called the Brain Performance Index, in which individual neuropsychological sub-tests were the dependent variable and EEG Phase delays, EEG cohereence, EEG amplitude, asymmetry, and EEG power were the independent variables. The multivariate regression equations, referred to as the Pricted Neuropsychological Score(PNS) also computes the + and - 95% confidence band as EEG prediction of performance on each neuropsychological test.
The correlation to I.Q. was approximately .58 and involved short time delays between the frontal lobes and the rest of the brain, elevated power, and lower coherence. These three combined measures give rise to an overall prediction of the efficiency of neural resource allocation.
