Is autism hereditary?

From what I know and have experienced, I most assuredly would say ‘yes’, if not though straight-up autism, then through autism-phenotype..

I have read that it is. Many of my family are/were autistic, no doubt, but only the youngest generation have been diagnosed. 

Autism is hereditary, but it had no real bearing on my own decision not to have kids. I think having family members who understand you is really important, so the hereditary nature of autism probably helps in some ways.

And no, being autistic isn't always a fun time... but we still deserve to be here. We have as much right to exist as anyone else does.

That's a remarkably offensive thing to say in a group for autistic people. I think what was said in your other post is right and you're just a troll trying to bait people. I've reported your profile.

You asked a question "is autism hereditary?" so I thought a few links would help with the answer:

www.sciencedirect.com/.../S2666247722000677
The heritability of autism spectrum disorder (ASD), based on 680,000 families and five countries, is estimated to be nearly 80%

www.psycom.net/autism-genetic
A recent study, published in JAMA Psychiatry, analyzed the data among 2 million people across five countries... Results of the study showed that 80 percent of autism can be traced to inherited genes

en.wikipedia.org/.../Heritability_of_autism
The heritability of autism is the proportion of differences in expression of autism that can be explained by genetic variation; if the heritability of a condition is high, then the condition is considered to be primarily genetic. Autism has a strong genetic basis.

Research tells us that autism tends to run in families.

While it's long been accepted that Autism Spectrum Disorder is heritable, no studies have been able to offer a genetic explanation.

Consensus in the scientific community seems to clearly point to it being hereditary although the exact mechanism of its transfer is not yet understood.

I've not come across any articles yet which have such large scale, rigorous studies that imply the opposite.

I'm 62 and had an autism assessment earlier this week and my autism will be officially confirmed in a few weeks. It appears that my great grandma was probably on the spectrum. My mum is too (but oblivious to the fact and will never be diagnosed. She has had a pretty decent life ) I "inflicted" autism on my daughter. She's doing just fine. And so am I. My granddaughter is also very likely autistic. We're great people.. I feel a bit uncomfortable with the idea of "not making any more" We are different not less. 

That was a typo. I used to look at the keyboard when I type, but recently, I can just type without looking at it.

Also, help me understand what the Plus Sign refers to: "+autism"

dude, it seems like you are in a dark place ... many of us can relate, but things can get better.

I can tell you about my experiences and ways I've found to make my own life better. If you relate to them, it may or may not help... 

Maybe I'm on the extreme side of the spectrum. I can watch a whole series of a TV show and aferwards I can't recall any of their names. I'm in trouble and have no idea who to talk to. I have a mental illness. I'm so glad I'm single without children. This only affects me.

I don't know what it is. I don't know what is happening to me.

Have you seen +autism in me Juniper?

It's a being-human "condition" :) While anyone - ND or NT - can have added difficulties and disabilities, I 100% believe core Autistic Traits can thrive with the right instruction and in the right context.

I've heard several NT individuals say they micro-dose on psilocybin to think like us.  

If I can stop it happening, I would. It's not something you would inflict on a child if you could prevent it. 

But now you know you are autistic, you can take steps to ensure any kids you have will have a good life.   

And can I just point out the implication of your question ... that we and your niece and nephew would be better off not existing.
