I've got a kid with definite sensory issues and some dyspraxia. He does not have autism.
Now, I will admit that some days, he looks close. But we had him evaluated this summer for anxiety, and one of the diagnoses that was considered was autism, and he clearly fell outside the range of autism/Asperger's for his social communication. So, his major issues ARE sensory. And probably anxiety too (though I think at the core, they may be related, because it's an issue of overexcitabilty/overstimulation and difficulty regulating 'input', whether that's sensory or emotional).
So, I've got a lovable, quirky kid with definite sensory issues.
