That's the challenge.
What's written and seen via YouTube usually comes from people without the disorder.
Because the disorder is so rare so is the factual information.

Sift through the AvPD forum past posts.
Granted that the large majority of information you read will come from those who don't have AvPD so that misinformation is in the mix- so you're welcome to question an old thread that we might be able to expand on. I don't always answer questions but there is another Avie on here who might answer what I miss.
