Sense of Touch and ASD Research

People with Autism Spectrum Disorder (ASD), Sensory Processing Disorder (SPD), and Attention Deficit Hyperactivity Disorder (ADHD) are often more or less sensitive to sensory stimuli than the general population. This can include the sense of touch. In my case, I am hypersensitive to touch.

I was curious if a certain mechanoreceptor in the skin may be involved in this sensitivity. And indeed, there has been some research done on this question. From what I've seen, researchers are linking hyper/hypo-sensitivity to touch in ASD to the Lamellar corpuscles. These are the mechanoreceptors that detect vibrations in the 250 Hz range.

Here are the sources that I found which discuss it. Collapse )
