Here's a quick list of online suppliers of medical equipment with a focus on neurological disorders and illnesses, such as ASD, Down's Syndrome, and head injuries, that I've found across many years of shopping online. Some of the items on these sites can get a little pricey, but they are specialty shops, so there may be similar products featured in different shops with a broader focus. I find that even if I can't afford something featured on these sites, I can at least get inspiration of what exactly I'm looking for by window shopping and then trying to find a similar product elsewhere.

NOTE: I'm a normal decent person so I hate AutismSpeaks. As far as I'm aware, none of these sites are sponsored or partnered with them, but if I'm incorrect about that, let me know and I'll remove the link.
