Left Handed and Autism

Well-Known Member
There are a lot of things that I do differently to the majority of the people, I have find the pattern that if I look if this have any relationship with Autism, I do find the connection.

Today the example is around being left handed.

What I take from this is that neurotipicals are 90% right and 10% left handed, while people with autism are more on the 50/50 spread, with some that are even mixed handed.

This is the generated answer that google gives me:

Relationship between Left-Handedness and Autism

Studies have shown a higher prevalence of left-handedness in individuals with autism spectrum disorder (ASD) compared to the general population.

Prevalence:
  • Approximately 28% of individuals with ASD are left-handed, compared to around 10% in the general population.

  • Some studies report an even higher prevalence, with up to 45% of individuals with ASD being left-handed.
Possible Explanations:

  • Brain Lateralization:
    Autism is associated with atypical brain development, particularly in the left hemisphere, which is typically dominant for language and motor functions. Left-handedness may reflect an altered balance between the hemispheres.

    • Motor Deficits:
      Some individuals with ASD experience motor coordination difficulties, which may make it easier for them to use their left hand.
    • Sensory Differences:
      Individuals with ASD may have heightened or diminished sensitivity to sensory stimuli, which could influence their handedness.
Other Considerations:

    • It's important to note that not all individuals with ASD are left-handed.
    • Left-handedness is also present in other neurodevelopmental disorders, such as dyslexia and attention-deficit/hyperactivity disorder (ADHD).
    • The relationship between left-handedness and autism is complex and not fully understood. Further research is needed to elucidate the underlying mechanisms and potential implications.
Conclusion:

While left-handedness is more common in individuals with ASD than in the general population, it's not a definitive diagnostic criterion. Other factors and assessments are necessary for an accurate diagnosis.

My parents reacted to my being ambidextrous the same in that I didn't look people in the eye. Another thing I shouldn't be doing, so I learned to use only my right hand for anything important.

Sometimes peer pressure seems really, really stupid. But an order was an order in our house. So much time went by I doubt I could ever again use both hands again with any sense of being equal. Oh well...

Sure, I don't know much about the workings of the forum, if you know how to set that up, that would be great.

It would have to have 3 options, for left, for right and for both... consider that mixed handed is different to ambidextrous... in that mixed handed might write with the right but do other things with the left, like hold a tool. Or the other case around, write with left but do other things with right.

In my case they try really hard at home and at school to have me to write with the right, it was all useless, so eventually they gave up and let me be... latter in life I self train myself to write with the right, granted a lot slower than with the left... my goal is to write with both at the same time.
 
I'm a lefty. I can write and draw somewhat with my right hand, but I only do that if I want something to look like a child drew/wrote it.
 
I was born left handed, my dad thought that was a bad thing so "converted" me to being right handed... I don't remember any of this, but was told this years later...

Functionally I am now very challenged with using my left hand effectively for some tasks, don't ask me try writing with my left hand :rolleyes:
 
I was fortunate to grow up right after schools stopped pushing lefty conversion therapy, and my parents thought I was just fine as is, so I got to be pretty much an unfettered lefty. The only specific activities in which that isn’t the case are those where my right handed grandmother taught me things like knitting. She tried to use a mirror and some other tricks, but I found it easiest just to mimic her actions directly. Surprisingly (not really) none of those activities became life long hobbies.
 
My mother was another one that was forced to write with her right hand when in school, she still sews and knits left handed though. When we were little she made us practice writing with our left hands as well, and writing with our feet. Part of that is just to teach small children finer motor control, but from her point of view it was practical knowledge as well, her family were all bush people and it's not uncommon for people to suffer injuries where they lose the use of one limb or another.
 
My dad (Aspie) was left handed, back in the days when being left handed was considered "wrong", so he was forced to use his right hand.

I'm right handed, but my left hand likes to jump in, if it thinks it can get away with it (weirdly, both hands work independently from my main brain, and are very good at doing their own thing).
 
I'm ambidextrious, I write mostly with right hand, more rarely left, some things I prefer do with the right hand, some left.
 
I was born a lefty and like many others here was forced to become right-handed only by my dad.
He walked in one day when mom was teaching me to draw and write and told her to stop letting me use my left hand. He thought it was a sign of not "being normal."
Now I can't do anything like writing with my left hand.

I always wondered if it is hard on the brain of a developing child to make them go against what comes naturally for them.
 
Went to party last night, they had pool table so of course played wife. Normally I could play with either hand.do not use rake unless in real awkward position. found out such lack of feeling in left hand, wacked ball it moved 2 inches.
Probably worst effect of stoke loss of being ambidextrous.
 
I have covered this topic before. MRI scans show that there are no marked differences between the NT and autistic brain. I am NT, so I'm impartial regarding this matter.
 
I was raised to be right handed, so that's my primary writing hand. But just about everything else I do the same or better with my left hand.

Back when I was 21 I broke my right wrist while roller skating. My right arm from elbow down was in a cast for 2 months. It wasn't difficult to get used to writing with my left hand. But my brain started working differently. At my job, we designed machines that transferred engine blocks from one machining station to the next, left to right. My brain started looking at these drawings from right to left. It wasn't hard to get used to using the mouse with my left hand. These days if I work on a lefty's computer, I use the mouse with the left hand just the same.

I am also left eye dominant. I didn't know this was a thing, but I learned it in hunter's safety. I thought everybody was. I figured that's why the viewfinder on cameras is always on the left side. But I guess it's not as common, because everyone I knew had their gun scope set up for the right eye, so I had to use it that way.

As a kid I had a skateboard. I always rode it right foot forward, and was told it was wrong, or "goofy foot". But I also had skateboard books, and when I saw a picture of Tony Hawk riding the same way as me, I knew it was ok. His board in the pic even had the tape angled to how his feet would go. I sanded down my board and redid it the same layout as his.

Autistic and Neurotypical Brains: Neurological Differences

I have followed the first link that you provided in your post, then another link within the article that led to the original article. I have read the article's abstract, and I'm skeptical about their findings. To start with, the number of autistic individuals participated in the study is 12.
Although it is possible to use small group studies to draw a valid conclusion, in general this is not recommended. I have participated in clinical drug studies of 30 or more participants. As a rule of thumb, the number of subjects of study in each group (placebo group and trial group) should be at least 30.
I don't have an access to the journal, so I cannot read the whole article and render the final conclusion. For me the validity of the study is far from being clear
