Difference between those diagnosed early to those diagnosed later

According to research theres different genes involved in those diagnosed as young children to those diagnosed later in life and certainly those of us who were diagnosed as adults. The research states that theres no one cause of autism and that multiple genes are involved.

There's an article on it in todays Guardian newspaper.

  • I did see this, but looked at the research paper, and what they said about sample sizes says it all. The usual suspects - 'limited size', 'mostly male' in the young group, and a lack of understanding of what the older diagnosed might have been like when they were young due to the knowledge gain over the years. It felt like another flimsy theory as unless they do a proper study of significant size and exam all factors, it felt like another false start. The problem being it's mostly pharmaceutical companies fund research if they think they can sell something at the end, and if you can't rewire brains they have no impetus to find out.

  • Smaple sizes in these sort of studies has always been a problem, it's one of the reasons why I like Gina Rippon's, The Gendered Brain so much, as she looks so closely at sample sizes and their make up. It's a problem with medical research in general, they always seem to end up with young white men, nobody wants to give untested drugs to children for obvious reasons, women get excluded because of menstral cycles making things "difficult", many minorities don't trust researchers not to be racially motivated. Although why they should exclude anyone who's not a young white male from studies on things like autism I really don't understand.

  • Studies are normally voluntary, so you can't study people who won't participate.
