This is certainly not news to those who work with young ASD children on sensory processing skills. The Journal of Autism and Developmental Disorders published research stating that young autistic children experience specific sensory sensitivities with regards to tactile input, taste, smell and auditory filtering when compared to other children with different developmental disabilities. The researchers recommend that these differences are considered as specific symptoms in young children with autism.
It still leaves the question - is sensory processing disorder a diagnosis or a symptom of other disabilities?? In my non expert opinion, this research study is a score for the theory that sensory sensitivities are a symptom and not a disorder by itself. Any comments?
