I know I harp on this topic and for that, I apologize.
My daughter has Triple X and I have been fervently posting on the forum for Triple X in regards to sensory issues we are facing.
There are a few moms who have a dual DX for their girls (triple X and ASD), but the overwhelming majority have Triple X and sensory issues. One mom took her daughter to see the Triple X specialist in the country and she told her Triple X girls have the most sensory issues out of any chromosome disorder she has even seen.
That said, I am now trying to figure out if the things DD does fit more of an ASD profile or a SPD profile. She was dx'd w/ PDD-NOS as more of a precaution to getting services. She didn't clearly fit into the ASD dx.
Re: How do you separate out ASD from SPD?
Do you think age is a factor, then? DD is 29 months and we didn't even see sensory issues until 24/25 months. Her sensory issues change, as well. Socially, she does pretty well one on one, but large, crowded places w/ screaming kids...she cannot handle. She is actually better about sharing toys and engaging than some typically developing kids are. Her eye contact is sometimes good, sometimes bad. She responds to her name about 80% of the time. She is aware of other's feelings/emotions and has asked me if I am okay (after I had a bad break down in front of her). She gets concerned when a baby cries and will even hand a crying child her own lovey.
She has a laundry list of sensory stuff, some very new. Just this morning, she was d-o-n-e with therapy, had a sensory meltdown and started running around on tip toes.
Is there generally an age when the dx becomes more clear? When the sensory issues should go away, but if they don't, then Houston, we have a problem?
I learned not to fully trust professionals during the arduos process of getting a dx for my DD.
And my DD talks (granted, she has articulation issues), is very funny and knows when she is being funny, is friendly and will look people right in the eye. And this is why so many people, including therapists and her own father, cannot believe she is anywhere on the spectrum. It seems that only time will tell us for sure at this point.
