Shelly,

Yes, there are evoked potential evaluations which can aid in the
assessment of central auditory processing disorders (CAPD).  The Middle
Latency Response (MLR) is currently receiving a great amount of
attention for diagnosing CAPD.  Another type of evoked potential which
may be used is the P300, which is a late potential.
