I'm afraid I don't remember, without digging thru papers, if ds has technically been diagnosed with it, but it definitely is part of his Aspergers and ADHD. The biggest thing is to have him tested and find out where this occurs. The school did their own testing, independent of the testing his Dr. did. All concur. He hears things, but may concentrate on only one sound, so doesn't hear the whole sentence. Therefore, it may appear he's listening, but he isn't.
He also has poor working memory, which is very challenging. However, he can tell you the name of every dinosaur and Bionicle out there.
In dealing with the school, the big thing the psychologist was stressing to the teachers is that just telling him how to do an assignment or learn something is not enough. He must see it, concrete. Also, if it's in front of him, he's studying it, he can't really process what direction she is giving. Therefore, if you veer off what is written, you must make sure to repeat it to him, ensure you have his attention, and write down as much as you can. My son also has motor issues, so it's not effective yet for him to take notes. Worse, a child taking notes is too busy taking the note to listen to the next thing the other person is verbalizing.
In a noisy environment, the person can't filter out background noise and listen to the person who is speaking directly at him. I have the same challenge in having him do homework. The TV is on in the other room, but he has to have it off. Homework here is very challenging because he has a younger sister.
Things can change with therapy and maturity. It used to be that I couldn't give him more than one task at a time. If I say, "Go in your room and hang up your shirt, feed your fish and bring me your clothes hamper", he'll go to his room and not think of why he's there. Or he'll go in, hang up his shirt, but not do the next two tasks. He's processed the first part of the sentence, but not the second.
He also can't process info very quickly. If you give him information, then change paths or change subjects, he has to stop you while he thinks of what you just discussed, putting it into his memory banks. Or he won't stop you, but believe me, he also isn't listening.
Because he hears sounds differently, or misses sounds, speech therapy has come into play. His is thru the school.
There is listening therapy available. I tried to get the school to give it to him, but it's still in the unproven, experimental stage, so they do not use it yet. I'm on my own. I have a friend who uses it and she reports it has helped a lot. She's going to try to get me a copy of the CDs, but if that's impossible (due to copyrights), I'll get the info to buy them.
I haven't looked up books on Amazon yet, but I'll bet there are some. I did find these sites, however:
Auditory Processing Disorder in Children
Auditory Processing Disorder
I really liked the info given on this one.
If you google it, you'll get up more info. I'm remembering now that he was diagnosed with it definitely...what is interesting is that I don't think it's in his IEP...note to self. I know the IEP addressed what is needed, but I think we need to add on. Thanks!!
