Mel, my DDs CAPD was diagnosed by an audiologist (it was noted by her OT and her psychologist but they are not qualified to diagnose in Australia). Her Dyslexia and ADHD will be assessed by a psychologist in September, I will be deeply shocked if she is not diagnosed with both.
The first time it occurred to me that DD might be deaf and we had her tested we were told that her hearing was spectacular and that her focus was beyond her years. No-one thought to ask why we had brought a child with such fabulous hearing to have it tested and the school did not suggest that if she acted like she had hearing problems but had perfect hearing then we should investigate further. We had never heard of CAPD so we stopped there. It was with the change of schools that we started down the path to diagnose everything, not just the CAPD.
My long winded point being - if your child has great hearing but seems like they can't hear you or doesn't listen well, then that would be the reason to investigate CAPD.
From my understanding Dyslexia is also, in the vast majority of cases, an auditory condition. It is not usually related to visual processing so much as to auditory processing. So it's not uncommon for the two to go hand in hand as I understand it. My DD had to be painstakingly taught to map symbols to sounds and painfully taught every possible phonetic rule there is (she knows them all, inside out), it took her until just this last term to read for pleasure (mid yr4) but she still has very poor phonemic awareness, her spelling is approximately 5-6 years behind her comprehension and her reading aloud is wooden and stilted.
