Ashleigh's vision problems were misdiagnosed as autism

Does our lack of understanding about vision mean that some children are being misdiagnosed with autism?

This happened to Ashleigh.

After being misdiagnosed with Asperger syndrome, Ashleigh later found out that her behavioural problems actually came from Cerebral Visual Impairment (CVI).

Not in Plain Sight, a documentary for BBC One Scotland, is available afterwards on the BBC iplayer.
