We saw a paed. OT who thinks my son has that - it can be related to some or all of the senses. Alex freaks out at birds, the vaccum, hairdryer, people singing etc. He has a very high pain tolerance, things that make me wince don't bother him at all. He also cannot handle some fabrics against his skin.

There is a tonne of informtion on the web.

The OT talked about Alex being 'on the spectrum' but didn't say autism.
