I included it to make the following point: Accessibility is more than catering for the deaf or blind. It also includes color blindness, mental handicaps or going by the standard:

Which have the following guidelines (or myths?):

  - allow users to control flickering, avoid causing the screen to flicker

  - allow users to control blinking, avoid causing content to blink

  - allow users to freeze moving content, avoid movement in pages

  While people with epilepsy are browsing web sites, they 
  may encounter pages that have blinking texts and 
  animation that may trigger seizures. Sudden loud sounds 
  and repetitive audio in some web pages can also cause 
  epileptic seizures.

I do not know much about epilepsy, so I will believe your experience, but believe me when I say I am not using it as a way to further a point. I believe in above guidelines, regardless if they help for epilepsy, because in this case they help other users with a mental handicap or ADHD and so remain good guidelines. Or do you rather have we don't mention epilepsy all together when making sites accessible and just call them common sense? It is easy to ignore even a common sense guideline when there are so many different ones.

It seems you have an uphill battle to fight if mentioning epilepsy and accessibility in one sentence gets up your nose. Like my quotes show, I am not the fringe 'defend epileptics' spreader of myths here, this is part of the accessibility topic.
