What percentage of people with ASD's are left handed?

Post Reply New Topic

What percentage of autistic individuals are left handed? Is it higher? I've read so but wanted confirmation. Is there any reason for this? Is there research into this. Articles,stats etc would be good

I know very few articles on the matter.

As for me personally, it's more 60% right, 40% left. Can write pretty well with both hands.

Have always read that for the general population its 10 percent left handed. And that its been that way for a long time. Most stone age tools of the Upper Paleolithic were made for left handed people Ive read.

It's a known phenomenon that there's a higher-than-normal percentage of individuals with neuropsychiatric disorders who are left-handed. It's really been studied in schizophrenia. Read up on the "testosterone theory." That's one hypothesis as to why left-handedness tends to occur more often in those with neuropsych disorders. It also explains why left-handedness occurs more often in males than in females (even in neurotypical individuals). I'm a big believer in this, as I am living proof. Both of my parents are right-handed, there is next to no left-handed individuals in my family (just two of my mom's cousins, who have very little genetic link to me), yet I'm a left-handed female on the spectrum who showed left-handed preferences in infancy.

I'm right handed, my dad is kind of ambidextrous, and my sister doesn't have a hand she uses more, so I guess she is ambidextrous as well.

I found this from 1983 of 26 autistic children: https://www.ncbi.nlm.nih.gov/pubmed/6580656

I'm left handed, and as far as I know I don't have an ASD. However, I'm probably not NT either. My parents are both right handed, but my sister and I are left-handed. Also, I have longer ring fingers on each hand and I was born prematurely, if that's relevant at all.

I'm a lefty Can a poll be added onto this thread?

I'm right handed and in my family only person who is left handed is my father and he is not autistic though he has his own share of mental issues.

I'm right-handed. A possible "forced convert" from left-handedness.

I was classically autistic at a young age. Aspergian at present.

It can change then can it? I've not heard of this before, people moving on the spectrum I mean.

I'm exclusively left handed, I'm also very awkward gripping a pen, and clumsy. So clumsy I've had to develop very fast reflexes to snatch whatever I've dropped out the air before it falls. I can only assume this is down to the spacial reasoning aspect. I've read people with aspergers have terrible spacial reasoning. I do, I'm not sure about other people.

I can certify that I was a classic autistic until I acquired speech at age 5.

Then I became more aware of things, and I presented more Aspergian after that.

There's a book called "Elijah's Cup," which depicts such a person.

To some extent, Temple Grandin was like that.

I would have to look up info: the only thing I already know is that I'm one of the very few left-handed people in either Mom or Dad's side of the family.

I'm the only known left-handed person on both sides of my family. I once read a study linking it to stress hormones in utero, which would make sense in my case, because it was a high-stress pregnancy. I can't find that study again, though.
