The qEEG brain mapping should have included VEP and AEP. Maybe the psychologist does not know how to read the test. The doc who did mine could look at the wave form and tell me what my symptoms are. But, my doctor did qEEG mapping research.
Yes, VEP, AEP and such are entirely objective tests.
Maybe researching qEEG testers in your area would help you find somebody who is a better test reader. Look at my previous post.
Here is an interesting research article about VEP and diagnosing concussion caused convergence insufficiency:
