To just remind you that autism is genetic?

Research tells us that 60 to 90% of the risk for autism comes from your genome. Maternal and paternal age are also a significant factor. Also genetic variants exist that cause autism-like behaviours and go undiagnosed because we don't routinely run genetic tests on our children. We also don't routinely institutionalise children that are different to their peers.

There's 'more' autism because people are having babies at older ages. And we are better at spotting autism.

It isn't heavy metals, microplastics, or the MMR.

Sorry, but it seems like every day I open this app and there's a new post saying 'What's going on with all this autism around, eh?' and a slew of replies blaming environmental factors that have no science behind them whatsoever. Or, worse, blaming mothers for reproducing too late in life or eating tuna in pregnancy or taking prescribed meds.

If you see enough of these threads every day you could well start to believe the nonsense that people write, much like people that read the Daily Mail every day start to believe that Meghan Markle is the devil.

Autism has always been here. It's not better or worse than it used to be.

No autism in my family or H’s family. DS2 has autism.
If it’s genetic I’d like to know which gene mutation is responsible for it.
It seems like a plague these days.

I spoke to a scientist about this. There are three main ‘causes’ of autism - two which cause intellectual disability, and one which doesn’t.

The first (Group 1) is a massive genetic mutation (or major congenital damage), which leads to children with major intellectual disability, epilepsy, etc. etc These are children who get diagnosed very early, end up in special school, and have very high support needs into adulthood. They are largely in families with no history of autism.

The second (Group 2) are ‘copy number’ genetic variations. These cause mild intellectual disability, but - again - largely aren’t uncomplicated inherited from parents. Again, the kids usually end up in special school and often have co-associated conditions.

The third (Group 3) is where the kids have inherited autistic traits from one, or more, family members. Increasingly, these kids get diagnosed in childhood and you’ll find whole families where every child, or almost every child, has a diagnosis of ADHD, autism or both. These children are healthy, of average, or above average, intelligence, and they usually have an autistic parent or grandparent. They don’t have any co-associated conditions that aren’t shared with a family member (i.e. if you get arthritis or migraines, your kids probably will).

It turns out there’s vastly more Group 3 than Groups 1 & 2, probably 10x more, but most adults in Group 3 were never diagnosed. About a third of diagnosed-autistic adults aged 30-50 registered with GPs in the UK have a learning disability. Only 10% of autistic children diagnosed under 10 do (90% don’t).

As such, there’s now a huge fight within the autism community between parents of kids in Groups 1 & 2, who view autism as a disaster that needs curing, and families of people where literally everyone is autistic (or ‘broader autistic phenotype’), who see themselves as ‘neurodivergent’, and simply requiring some adjustments to live a happy, productive life.

Most research was done on people who are now adults and, as such, most autism resources assume the vast majority of autistic people have learning disabilities. This isn’t the situation on the ground and it’s obvious that researchers haven’t yet caught up. Some of the increased diagnosis is due to changing classroom settings (e.g. talking in class for group work) along with powerful noisy new technologies, such as Dyson hand driers, which many autistic kids struggle with.

Both my children are group 1 or 2 -both in special school, no family history of ASD or LD. The fact there are two of them suggests a similar genetic issue and we are under genetics team at the NHS to try to identify.

It is SO clear you don't work with significant numbers of children U10 in any capacity.
Such a completely ridiculous statement.

Yes, I come from a family of neurodivergents, both diagnosed and happily unaware. In amongst the hypermobility, epilepsy, chronic migraines of all varieties and autoimmune disorders. We have pretty wonky genes.

I think we may be related 😂

GladiatoooorsReadyyyy · 02/07/2024 20:49

I have twins. One is autistic, one isn’t. A friend of mine has the same. How does that work then?

Katemax82 · 02/07/2024 20:34

I was 23 when I had my autistic son, my husband was 33. I always thought he got it from me up I was assessed a few years ago and turns out it's more likely my husband who has it but he won't get assessed. My youngest son has it also but I was 36 and my husband 46 when he was born

I'm autistic too. I was mostly talking about risk v chance. The other bit is about respecting what the majority of the community prefers, not dictating to individuals how they describe themselves.
And yes, I will go there because it's important.

I'm sorry, I seen to have missed the time where the autistic community had a formal vote and agreed to be bound by the results. Does that mean I lose my special badge? There is no such thing as 'the majority of the autistic community'. It may be the majority of the people you interact with but we are a diverse group of people and no one has the right to dictate the language we use.

You do you. If distinguishing between 'risk' v 'chance' is important to you, then go ahead and ask and explain why. Just don't dictate to me what language I have to use.

For me, language is the easy thing that the NT world can use to say that they accept neurodiversity. I see it all the time at work - get the language right, talk about superpowers and being your authentic self, and somehow we're all good. That's why I really struggle to care about language. For me, and the world I operate in, there are bigger fish to fry.

Is your son still in school? Because if you have true understanding about autism you’ll know that issues at school is only start of a lifetime of struggling. My eldest was exactly the same, ok until he start primary. Not because of the work structure expected but because neurotypical children start to emerge from the ‘selfish toddler/preschooler’ stage into social beings. And this is where the disability of autism starts to emerge, where the delays even in children with seemingly low needs will become apparent. In small spaces, and certainly safe spaces like home, of course people with autism will be more comfortable being themselves. School and the world beyond is an exhausting place beyond that and a lot of support is needed.

Yes, he's still in school. He's seven. He lives in a big city and travels around all over with me (and DS4). Most of his obvious problems are sensory and are (relatively) easy to fix by avoiding sensory triggers. I have similar sensory issues and, thus, part of the ease is that the places he doesn't want to go, I don't want to go either.

He's never going to be the life-and-soul of the party, but being a super extrovert with the charisma of Bill Clinton isn't the normal human condition.

DS4 does have the charisma of Bill Clinton, despite being diagnosed autistic. He has five friends, including a best friend, and attracts excited football chanting of his name whenever he goes into nursery. Again, massive sensory issues...

I think there's a cluster of 'stuff' that gets merged into autism diagnoses. It's not even clear it's down to the same neurological mechanisms...

The problem is that it's not 'a thing'. It's lots of things. And, in some cases, it can match the model of social disability.

I have no problems with my older DS at home. He had no problems at an (outdoor) nursery. The minute he got to school, his support needs were so high that he's now got an EHCP. It's like 'if he'd been born in the 12th century and we were living/working in a forest in a rural area, would he even be disabled?' It all feels weirdly contextual...

Let's not go there please. A large proportion of people commenting on this thread are autistic/have autism. People can describe themselves however they want, and there is by no means a unified position within the autistic community on whether is should be 'has autism' or 'is autistic'.

I'm autistic/have autism, and personally have far bigger concerns than language.

stayathomer · 02/07/2024 20:13

Only one diagnosed in our family but we could easily be the poster family for autism. I used to go to a lot off autism seminars and talks and support groups and the thread running through with most people I talked to who were advocating for children or siblings was they were nearly sure they/ other family members were autistic, just to a lesser extent (and always explained away as kooky/odd). It always drove me a bit crazy when some of the people said about how they couldn’t/ didn’t relate to whoever had autism as I could almost see it in them too. I can honestly say that if they ever proved without doubt that autism is not hereditary in a huge number of cases I’d be floored!!!!

Who’s ’these people’ exactly? Do you know what autism is? Seriously, anyone who thinks like this really needs say what they think autism is and detail why is not ‘that big a deal’ in their minds. It’s not a differential in personality or comparable to sexuality or a fucking allergy.

What annoys me is people consider this an 'illness' and like there is something wrong with these people. And there simply isn't.

Overall, humanity is total shit in dealing with different people than the norm, be it autism, allergies, sexuality ... whoever is different is being explored as a speciment that needs analysing and fixing.

It's not an illness but it is, in some cases, a severe disability.

I think people get muddled with disability and illness.
It bugs me when people say autism is a superpower, or that it’s not a disability. I think that really minimises what it can be like, particularly if you don’t have a structure that works for you.

yes, it's a bucket diagnosis and people tend to lump learning disabilities in with 'autism' - possibly because autistics tend to have 'spiky' cognitive profiles and people traditionally don't bother to work out if someone who can't use 'mouth words' (i.e. speak) is otherwise cognitively able.
isn’t it more likely that it’s because the majority of people with autism also have learning disabilities?

They don't. If you look at the government's latest autism need report, 90% of children with an autism diagnosis under the age of 10 registered with a GP don't have learning disabilities.

This rises to 34% in adults above 30/35 (I forget which) because the vast majority of adults without learning disabilities never got diagnosed as kids.

All the historical research has been done on the children who are now adults - hence, all the stats claiming most autistic people have learning disabilities.

This is where all the debates about 'profound autism' come from. Parents of autistic kids with very severe learning disabilities are now vastly outnumbered by the parents of children who are 'just autistic', and they're trying to create a new 'type/category' of autism to avoid their needs being ignored.

Is that Jaguar Land Rover?

I once knew a very old man who had been a chemist at Rolls Royce (aeroplane engines not the cars) and he often talked of it being a hotbed for odd men, he included himself in this, who were monumentally clever but needed to be looked after outside of work.

He lived with his sister all his life. She married, had children, but looked after her brother all his life. Looking back he was undoubtedly autistic.

Ridiculous. I have 2 x diagnosis as do my 3 dc. Their cousins have x2 diagnosis and their grandfather, great aunt and great grandfather would have been diagnosed I’m sure. None of us live in the same area and had very few meds growing up.

What is ridiculous is that you have no idea what I am referring to, but just jumped to your own conclusions. I wasn't talking about autism per se, I was confirming what RatHole said about pharma companies and suppression of research in general. For what it's worth we have clear genetic links to autism in our family, but I also think there's other factors, so do jog on with your outrage.

So hello question.

They lump it together because the traits are the traits.

Sarah who is "highly functioning" has low support needs but may struggle in different areas and excel in others.

Sally who need additional help around the clock ,has high support needs. And requires help in many different areas of her life.

They are both ND.

It's a spectrum, not a barometer. You're not a tiny bit autistic, you are or you aren't.

ND people have variable needs like any other human.

That's not really the question the other poster was asking...

@WorriedMama12 yes, it's a bucket diagnosis and people tend to lump learning disabilities in with 'autism' - possibly because autistics tend to have 'spiky' cognitive profiles and people traditionally don't bother to work out if someone who can't use 'mouth words' (i.e. speak) is otherwise cognitively able.

Also, there are a lot of people in the autism community who are trying to keep together a coalition of families containing members with severe learning disabilities and families with 'familial autism', by talking airily about varying levels of support, and - yes - there are people with such massive 'spikes' that they have wildly-varying support needs. But most people posting on Twitter/X have an above-average functional IQ in at least one area, even if they need a support worker to help them cope with the noise/lights in the supermarket.

That said, all of us can agree that people, whatever they're able to do, deserve respect, love, dignity, and a fulfilling life. It frustrates me that some autism activists try to pretend my DS are the same as a DS who needs 24/7 care - and it does come down to learning disabilities (or not). That doesn't mean I think autistic people needing 24/7 care deserve to be neglected or abused :(

Waffle78 · 02/07/2024 19:51

We have 5 in our family so there's obviously a genetic link. I know a few people with more than one autistic child. I was lucky my DC were diagnosed when the NHS was properly funded. We didn't have to wait long for a diagnosis and support was put in place before they started school.
