What Causes Autism? Myths vs Facts
There is no single cause of autism. The evidence points to genes and to differences in how the brain develops very early — often before a baby is born — and nothing a parent did, ate, feared or failed to do makes a child autistic. This page sets out what is genuinely known about what causes autism, corrects the eight myths parents in Multan hear most often, and explains what actually helps once the question of why has been put down.
Families usually ask us this quietly, a week or two after a diagnosis, and often in Urdu: autism kis wajah se hota hai? They have been awake half the night reading, and have found blame where they went looking for answers. If you want the practical side first, our autism support program in Multan explains what help looks like week to week.
What causes autism?
Autism is caused by differences in how the brain develops, and those differences are strongly linked to genetics. For most children there is no single cause, and no test that can name one. Researchers describe autism as many small genetic and biological factors acting together, usually beginning before a baby is born.
Autism spectrum disorder (آٹزم) is a developmental difference, not an illness. It shapes how a child communicates, how they connect with people, and how they take in sound, light, touch and texture. It is lifelong. It is not contagious, it is not a punishment, and it is not the result of anything that happened in your home. If the word itself is still new to you, our plain-language overview of autism in children is the place to start.
Is autism genetic, and does it run in families?
Genetics is the largest known factor in autism. Autism does often run in families, which is why parents recognise familiar traits in an uncle, a cousin, or in themselves. In most children it is not one faulty gene but many small genetic differences combining, which is part of why no two autistic children look quite the same.
Occasionally a specific genetic condition sits underneath the picture. Whether that is worth testing for is a decision for a developmental paediatrician, and the answer, if one is ever found, does not change the teaching your child needs tomorrow.
Does cousin marriage cause autism?
Cousin marriage does not cause autism. Marriage between close relatives is known to raise the chance of some inherited conditions in general, and genetics do matter in autism, so the two get tied together in conversation. But most children of cousin marriages are not autistic, and plenty of autistic children have parents who are not related at all.
In our experience this question rarely arrives on its own — it arrives with blame attached, and usually aimed at the mother. Please put it down. If your family genuinely wants to understand its own genetic picture, that is a conversation for a doctor, not for relatives at a wedding.
Did something in pregnancy or during the birth cause it?
Almost every parent has a candidate ready: a fall, a fever, a caesarean, a fright, a medicine taken for two days, working late into the pregnancy, feeling low afterwards. None of those everyday things is an established cause of autism. The differences behind autism are part of how the brain is built, and that building starts long before the moment you are blaming yourself for. If a doctor has said something specific to you about your pregnancy or your child’s birth, ask them directly what it does and does not mean — rather than filling the gap with a search engine at 2am.
Do vaccines cause autism?
No. Vaccines do not cause autism. The question has been examined in very large studies across many countries and no link has been found. The single 1998 study that started the claim was retracted by the journal that published it. Delaying vaccines does not lower the chance of autism; it only leaves a child open to serious illness.
In Pakistan this fear usually attaches to the polio drops or the MMR injection, and it does so for an understandable reason: those are given at roughly the same age the first clear signs of autism become visible, somewhere between twelve and twenty-four months. That is a coincidence of timing, not a cause. The signs were forming earlier, which is why many of the earliest signs of autism can be spotted in babies months before any of this.
Eight myths about what causes autism, gently corrected
These are the eight we hear most often in our clinic room on MPS Road, and every one has been said to a parent by someone who meant well.
| What you may have been told | What we actually know |
|---|---|
| “The vaccines did it.” | No link found in very large studies worldwide. The study that started the claim was retracted. |
| “The mother was cold with him.” | An idea from the 1950s, long since abandoned. Warmth neither causes autism nor prevents it. |
| “Too much mobile and TV.” | Heavy screen use does eat into the talking and playing hours a child needs, so it is worth cutting. It does not cause autism. |
| “It was the diet, the sugar, the formula milk.” | No food causes autism. Diet matters for a child’s health, not for whether they are autistic. |
| “Nazar lag gayi hai.” | A common and understandable belief, but it does not explain a developmental difference — and acting on it instead of getting an assessment costs time. |
| “It is because they married within the family.” | Close-relative marriage raises the chance of some inherited conditions in general. It is not, on its own, a cause of autism. |
| “Autistic children cannot learn or love.” | They learn, they attach, and they love — often fiercely. What they need is teaching pitched at how they process information. |
| “The right injection or diet will cure it.” | Autism is not an illness with a cure. Communication, skills and confidence can grow a great deal with steady, well-aimed support. |
What about nazar, taweez, or “someone has done something”?
Faith and prayer bring real comfort to families, and we would never ask you to set them aside. But the evil eye (نظر), jinn and magic do not cause autism, and treating them will not change how your child’s brain handles language, sound or social information. What changes that is teaching, repeated patiently, pitched at the level your child is actually at.
So pray if praying steadies you. Our only request is that it runs alongside an assessment rather than instead of one — the families who lose the most ground are the ones who spend two or three years looking for a spiritual cause first, because those are exactly the years in which a child learns fastest.
If the cause cannot be changed, what actually helps?
Support helps, and it helps most when it starts early and stays steady. Therapy is not a cure and does not change who your child is. It builds skills, takes the heat out of frustration, and gives your child a reliable way to be understood — which is usually what a parent is really asking for when they ask about a cure.
- Speech and language therapy builds a way to communicate now — words for some children, and pointing, gestures, photographs or picture cards for others.
- Structured behavioural teaching breaks a skill into small steps and teaches them in order. If that is unfamiliar, what ABA therapy actually involves explains it without the jargon.
- Daily-living and sensory support works on dressing, eating, sitting, and coping with noise and crowds — the things that decide whether a school day is survivable.
- Parent coaching is the quiet lever. Your child spends a handful of hours with a therapist and every other hour with you, so what changes at home carries the most weight.
Some children arrive here with a diagnosis and some arrive with only a worry that they are late to talk. If you are still weighing that up, speech delay and autism differ in specific, checkable ways, and our is my child autistic checklist walks you through what to look for before you speak to anyone.
What can I do tomorrow morning?
None of this requires equipment, English, or a diagnosis. Pick two and do them for a week.
- Get low and wait. Come to eye level, hold up the thing they want, and count to five before you fill the silence. Waiting is the most under-used technique in any home.
- Follow their lead for ten minutes. Play with what your child has already chosen, at their pace, without redirecting. Attention is easiest to borrow from inside their own game.
- Say one word more than they do. They say “car”, you say “red car” or “car go”. If they use no words yet, pair one clear word with one clear gesture.
- Halve your instructions. Short, concrete, one step at a time, with a gesture attached. Long sentences do not teach; they fill the air.
- Answer every attempt immediately. A look, a point, a sound, a hand pulling yours — respond as though it were a sentence. That is what teaches a child that communicating works.
- Book a hearing test. Glue ear and hearing loss are common, easy to miss and treatable, and they change how a child responds to their name.
What a first visit at our Multan centre looks like
Inclusive Developmental and Therapy Center is on MPS Road in Block A, Model Town, Multan, near Bloomfield Hall School, and was founded by Mahnoor Baloch, Speech & Language Therapist. The first consultation is free, and you do not need a diagnosis or a referral to come.
Most of the first visit is spent on the floor with toys while we talk to you. What we are watching for is specific: whether your child turns to their name in a quiet room, whether they point to show you something as well as to ask for it, whether play is functional or mostly lining up and spinning, how they let you know they want something, how they handle noise, textures and the end of an activity, and the gap between what they understand and what they can say. We then talk you through a developmental assessment if one is the right next step.
What usually changes first is not speech. It is requesting — a child who has been screaming for the biscuit tin starts pointing at it, or hands over a picture card. Sessions run around forty-five minutes, usually once or twice a week, and we work in short blocks with a review at the end of each one.
What would make us send you elsewhere first. If hearing is in any doubt, we ask for a hearing test before anything else. If you need a formal medical diagnosis — for a school place or official paperwork — that comes from a developmental paediatrician or a psychiatrist, not from us, and we will say so and tell you who to see. And if your child has lost skills they clearly had before, or has had any seizure-like episode, see a doctor that same week; that is not something to work around in a therapy room.
You did not cause this
If you take one thing from this page, take that sentence. The cause of autism is not something you chose, and for most families it will never be pinned down to one thing. What is within reach is the next step: understanding how your child communicates, and building on it patiently from wherever they are today.
If you have questions turning over in your mind, or a report you do not understand, talk to our Multan team — call or WhatsApp on +92 314 6040262, Monday to Saturday, 10am to 7pm. No judgement, no pressure, and no charge for the first conversation.
Diet is where a great many of these promises land, so we have set out what the research actually shows in our guide to food, feeding and your child’s development — including why removing wheat and dairy from an already narrow diet carries a real risk.
Frequently asked questions
Will a test ever tell us why our child is autistic?
For most children, no. There is no blood test or scan that names the cause of autism, and in the majority of families no single cause is ever identified. Occasionally a specific genetic condition is found, and a developmental paediatrician is the person who decides whether that testing is worth doing. Either way, the answer does not change the support your child needs.
Did my parenting, or screen time, cause my child’s autism?
No. Autism is not caused by parenting style, affection, discipline, diet or screen time. These ideas are myths, and they leave families carrying guilt they never earned. Autism comes from differences in how the brain develops, largely genetic, beginning very early in life. Cutting screen time is still worth doing, because it frees up hours for talking and play, but it is not a cause.
Should I delay or skip my child’s vaccines now that he has been diagnosed?
No. Vaccines do not cause autism, and skipping them will not undo or ease it. Very large studies across many countries have found no link, and the single study behind the claim was retracted by the journal that published it. Delaying vaccination only leaves your child exposed to illnesses that are genuinely dangerous. Speak to your paediatrician if you are worried.
Is autism curable?
Autism is a lifelong way of experiencing the world, not an illness with a cure. That said, a great deal can change. With early, steady support many children build communication, independence and confidence, and family life gets easier as frustration falls. The goal we work towards is not a different child but a child who can be understood and can join in.
My child is non-verbal. Can therapy still help?
Yes. Being non-verbal is the start of a different route to communication, not the end of one. We build a way for your child to be understood now — pointing, gestures, photographs, picture-exchange cards or a simple app — while still encouraging speech. Giving a child a reliable way to ask does not stop them talking, and it usually takes the heat out of the behaviour that frustration was driving.
Is it too late to start if my child is already seven or ten?
It is not too late. Earlier is easier, and we will not pretend otherwise, but children and teenagers keep learning language, self-care and social skills well beyond the early years. With an older child the goals shift towards being understood at school, managing daily routines and coping with frustration. We work with children from two to sixteen.
Is stem cell therapy, or a special diet, a treatment for autism?
Neither is an established treatment for autism, and neither is part of any standard care pathway. Families are sometimes offered expensive options that promise a great deal. Before you spend on any of them, please ask your child’s paediatrician what evidence sits behind it. Money and months spent there are money and months not spent on teaching that reliably helps.
