Q

Compared to a normative database, a client’s EEG power values are 2 standard deviations away from expected values. Which of the following describes how a clinician might interpret the results?

B. Any data different from the statistical database represents a clinical or functional abnormality.
C. The clinician could explore the client history to match symptoms from the client that correlate with the identified difference from expected values.
D. The clinician would not interpret the results; it is unacceptable for anyone other than a physician skilled in clinical application to interpret QEEG data
