DS is 2 1/2. We've been working with EI for a year now, the initial concern being language regression. His ped dismissed our concerns at his 12 month appt, and at his 2 year, she referred him to be tested for Autism. Now we are working with a Behavior Ped, almost 2 hours away. I really feel like his main issue is SPD, not Autism, but feel that it is important to continue with this Dr. The Dr is wanting to figure out why DS is not speaking, so we're working through a 'check list' which includes cognitive testing, hearing test, OT eval, genetic testing, and some other things including an EEG. I feel at this point the EEG is not really necessary, and am wondering about the genetic testing as well. I know that unnoticed seizures are possible but I just don't think that putting him through that will really be beneficial. They want him awake, but will put him under (IV I think) to do the test since he will not tolerate it. I'm looking to get some opinions of others who have gone through this.
