Research and Causes

The great portal/blog Left Brain / Right Brain has a lengthy post on current research dealing with potential causes of autism. The post offers links to multiple peer-reviewed studies underway on the familiar suspects, ranging from mercury to the age of parents.

Of course, no amount of research will influence the zealots, but I can at least suggest reading the actual studies underway:

Again, I can only suggest reading and following the research. Many of the early findings demonstrate what we already know: mercury and other toxins are dangerous. What the findings do not, at least not yet, demonstrate is that mercury or other heavy metals are the primary cause of autism.

Mercury exposure in adults does cause neurological damage. This is generally not genetic in nature, but is serious neurological damage affecting the brain and central nervous system. When we find genetic markers, that is a different form of damage. Birth defects can be caused by toxins, without a doubt.

It is unlikely we will locate a single cause for the genetic damage associated with some types of autism. I do not believe mercury will be a major factor, but data are needed. I also hope people understand that genetic damage cannot be caused by a vaccine -- genetic damage occurs before birth. This does not mean the mother or father wasn't exposed to toxins or other factors causing damage to DNA passed on to a fetus.

My point is that we should follow serious research. It is underway and should help eliminate some theories. Research can only disprove the null, it cannot prove with complete certainty anything. Again, that's very difficult to explain, so I won't try in this posting.

I'm hoping the research projects exclude a great many theories so we can move ahead.

Autism, Asperger's, and IQ

"Aren't people with Asperger's more likely to be geniuses? Isn't genius related to autism?" A university student asked this in a course I am teaching. The class discussion was covering neurological differences, free will, and the nature versus nurture debate. The textbook for the course includes sidebars on the brain and behavior throughout chapters on ethics and morality. This student was asking a question reflecting media portrayals of autism spectrum disorders, social skills difficulties, and genius. I did not address this question from a personal perspective in class, but I have when speaking to groups of parents, educators, and caregivers. Some of the reasons these questions arise, as mentioned above, are media portrayals and news coverage of autism. Examples include: Television shows with gifted characters either identified with or assumed to have autistic traits: Alphas, Big Bang Theory, Bones, Rizzoli and Isles, Touch, and others. Some would include

Scott on Fall 2023

Normal life has made it difficult this fall to maintain the podcast, my blogs, and my social media accounts. I have no idea how other working parents with podcasts and blogs manage to produce any content during a school year. Trying to produce episodes at least monthly proved beyond my stamina. After months like November, I find myself envying full-time creators who earn a living producing quality podcasts, videos, blog posts, and social media. They have tens of thousands or even hundreds of thousands of subscribers and followers. Their podcasts have sponsors. Many of them have small teams or they outsource editing and transcription of content. And then there are the dedicated hobbyists. That’s me: a slightly insane, certainly overwhelmed, and sometimes on-schedule hobbyist.
