Hi K,
As you know C-Dog was just diagnosed with a vision processing issue. I think you can have DS4 tested because the Dr. said something about age-norming DD's results and it would all be in the report we are supposed to get.
I didn't even talk to our pediatrician about it.

We saw him the day after her test, for school exam, and I told him. He just said, yes, it's genetic, runs in families, glad you caught it blah blah blah and that's about it.
I saw trouble earlier, probably since about 4 or 5. Things that stuck out were that C-dog started reading sentences at 3 then never pursued it further, but I justified that as being possibly other issues because of her age. Her handwriting is awful. It's obvious that she had fine motor issues, and the eye is fine motor so.......but that's also a different issue, I think.
She also was flipping letters and numbers, but the problem is that it's totally age appropriate for children that are developing intellectually in a normal rate, so it's hard for a Dr. to tease it out at his age.
I looked for a Dr. at : covd.org
I talked to the Dr. prior to the interview. I basically told her C-dog's IQ results and ALL the history that I could think of that I thought was relevent, including that her K teacher thought she was..........well, you know all that.
I think that's what made the difference and why the Dr. took a very close look instead of saying something like, we'll take a look again in a year or so,,or whatever.
I got this link on the forum and had C-dog attempt all the excercises. They are fun little video game type tasks for kids, she liked it. The issue she had stuck out tremendously and that's what made me finally make the appt.
http://www.eyecanlearn.com/Can't help you out with other processing issues such as auditory. Sorry. Oh one other thing, phonics seems to be an issue with vision processing or visual spatial learning types. C-dog did not get phonics AT ALL.. She took a computer class this summer for phonics and it finally clicked, but it was very different than her sister. She literally learned to read by memorizing sight words. Now she gets phonics, but we had to have her do a special program at a learning center. It seemed very unusual.
Hope this helps.
