Question about PDD-NOS with relation to Apraxia and SID
My DS is almost three and a half and is diagnosed with speech apraxia and sensory integration disorder. He fits these profiles very well but lately he has been showing new behavior that as his mom I feel is beyond his diagnoses. For one he is now becoming very sensitive to sound to the point he will put his hands ove his ears when he hears certain things, like a baby crying. In the past the only sensory issue he has had is in relation to touch. Stuff like he cant stand his hands, face or clothes being wet. He screams bloody murder when I wash his hair. He also does stuff like lining up his cars in one long row across the floor, and spins in circles till he falls down.
He is very outgoing and likes people but is very hard to get to make eye contact. I will come down right to his level and say look me in the eye and he will for half a second and then look every other direction then at me. He doesnt talk much but he never has.
His speech therapist and occupational therapist dont seem to think anything has changed in him but my moms instinct is screaming something is changing.
I think they just dont want to repeat the IEP since we just recently did it. How do I go about getting my son tested for PDD-NOS, or better yet is there a test for that. How is is different then autism? anyone have advice for me? am I being paranoid?
