The present invention provides a method for diagnosing, detecting and monitoring brain function, especially neurological diseases and disorders. This invention examines the output of a neurological monitoring device such as an electroencephalography (EEG) recording. The EEG recording is often taken while a person is engaged in a specific neurological task such as delayed recognition. This invention provides for two methods for the diagnosis, detection and brain monitoring based on the EEG recording. The first is the use of the person as their own baseline for comparison. The efficacy of a person's brain function is measured by comparing a portion of their EEG recording with a different portion. Each of these portions is taken from the same EEG recording of a single neurological task performance. The second method is the minimal use of monitoring device output, such as an EEG recording, in a manner congruent with the neurological task being performed by the person. For example, to test a person's delayed recognition memory; a person would first be required to perform a delayed recognition memory task. Then, the EEG recording for two electrodes, P3 and P4 would be examined for the first 150 milliseconds after recognition memory stimulus onset. Then the EEG recording for two other electrodes, T7FPp1 and T8Fp2 would be examined for the next 150 milliseconds. Since this choice of electrodes and times is congruent with the neurological task of delayed recognition, the data is highly relevant to the monitoring of the person's delayed recognition memory. This method, combined with using a person as their own baseline allows this invention to provide high accuracy in the detection, diagnosis and monitoring of brain function, especially neurological diseases and disorders.
