Numerous research studies have found it to be very sensitive to general brain dysfunction and it is frequently used to assess executive functioning. This advance edition of the MeSA-AE test can be used to evaluate individuals between the ages fifteen to eighty-nine years old. Since the test administration, scoring and interpretation are automated, this test can be easily and accurately administered by an examiner’s assistant.

The test by itself is not to be used as a stand-alone instrument in making any determination of impairment or diagnosis. Its primary function is to provide data that may prove helpful to clinicians as part of their comprehensive evaluation.
