My daughter never had speech, and was an early talker. But she asked "What?" all the time. She passed all her hearing tests, but I knew something was off. When she started struggling, her Dr and teacher said ADHD. But that didn't seem it to me. My 2 year old was in speech, special ed, and OT for his delays, and the OT that evaluated him mentioned APD to me. That was like a year ago, but all of a sudden it popped in my head, and I looked it up. My daughter fit almost all of it. We are lucky enough to live near a specialist in APD, who designed the testing himself. Her case is extreme, and it was surprising how well she has already coped.
In fact, her coping ability seems to have counted against her. She has a 504 plan, and they doubted her test results because she is doing average in school. With as bad as she tested, especially with background noise/overlapping voices, you would think she would be doing much worse. But what we now know is APD comes across as inattentiveness. And it seems like people don't get that inattentiveness is also a symptom of APD.
Her APD was diagnosed in November 2011, so it is still pretty new. In January was when she told us about her "episodes" when she sees, hears, feels unusual things. Same as her APD, she thought it was typical, and that everyone experienced those things. We have noticed her memory has improved a LOT with the medicine. Like A LOT! She still has some issues with memory because of her APD, but I think a big part of it was the seizures.
Sorry about the novel, lol.
