Start with a phone call. Your doctor’s office has a triage line and a nurse will talk it through with you. They are genuinely good at this, they do it all day, and it costs nothing. Most practices have a phone line where a nurse takes calls about whether something needs to be seen, and how soon. It is often not advertised — you ring the main number and ask to speak to the triage nurse. There is no charge and you do not need an appointment to use it.
If it feels more serious than that, go to urgent care. You will usually be seen faster than at a hospital, and the care is good.
If it feels life-threatening, call 911 or go to the emergency room. Do not wait until you are sure.
Which one is yours to decide, not ours. But our advice is to assume it is worse than it looks and take the more cautious road. And trust your body — if it is telling you something is wrong, it is probably right. The best possible outcome of a trip to the emergency room is walking out saying well, that was a waste of an evening — but I feel a lot better knowing it is nothing serious.
Before you call, have these ready. They are what the nurse will ask, and the call goes better when you are not working them out on the phone.
You are not diagnosing yourself by having this ready. You are handing them the things they would otherwise spend the call extracting — and the decision stays entirely theirs.
Writing to the portal instead of calling? The same list works, in that order, in one message. Put the direction it is going and the immune-system line near the top — portal messages get read quickly, and those two change how the rest is read.
These are about seizures. Tick anything true right now.
What we would do, as a friend rather than as your doctor. This is our opinion and we stand behind it. It is not medical advice and we are not examining your child.
If you have rescue medication and a plan, follow your plan. It was written for your child and it beats anything on this page.
None of them? Then nothing below is an emergency, and you can read at your own pace.
The short answer, before anything else.
SYNGAP1 is a gene. When one copy does not work, there is not enough of the protein it makes. That single fact explains most of what follows: the seizures, the delay, the trouble with noise and crowds, the sleep.

Autism is a description, not a cause. Being given that description does not rule out a genetic cause underneath it, and looking for one changes what can be done.
→ where this is explained: What this page is about
Some seizure types point at it specifically — much more than others. If you have a phone video of one, bring it. It is often worth more than the description.
→ where this is explained: The seizures that point at it specifically
The one thing to do next: Worth asking: “He has autism features and seizures. Has anybody looked for a genetic cause that would explain both?” and “Which genes were on that panel, and was a microarray done as well as sequencing?” Sequencing alone can miss it.
Everything below explains each of those, in whatever order suits you.
SYNGAP1 is a gene. Everyone has two copies. It makes a protein that acts as a brake on brain signalling — it helps the brain filter, time, and settle down after being stimulated.
When one copy does not work, there is not enough of that protein. The brain is not damaged. It is under-braked. Signals arrive without being filtered or timed properly.
That single fact explains most of what follows: the seizures, the delay, the trouble with noise and crowds, the sleep.
Across children identified with it:
GRADE B These figures are carried from this project’s own SYNGAP1 work rather than re-checked against the primary papers today. They are good enough to tell you what to ask. They are not good enough to quote.
And one caution that matters for every number above. They describe children who were found to have it. Children with milder versions may never be tested, so the real spread is probably wider and gentler at one end than these figures suggest.
Some seizure types are much more suggestive than others. If any of these sound familiar, that is worth saying out loud to a neurologist:
If you have a phone video, bring it. Thirty seconds of footage settles questions that an hour of description cannot. Neurologists ask for this and are glad to get it.
Pick whichever sounds like your family. There is no wrong door and no right order. Each of these feeds the next, and the last feeds the first.
Autism features are present in about two thirds of children with SYNGAP1, so the description fits. It is not a wrong observation.
But autism is a description, not a cause. It says what is happening. It does not say why.
The combination that should prompt a genetic test: autism features plus seizures plus intellectual disability. Autism alone, in a child with no seizures and typical development elsewhere, is a different situation.
GRADE A That developmental delay with epilepsy warrants genetic testing is standard practice, not a fringe view.
“He has the autism diagnosis and he has seizures. Has anybody looked for a genetic cause that would explain both?”
“Genetic testing” is not one test, and a normal result may mean the test did not look.
Two things worth checking, and both are reasonable questions:
GRADE B The deletion proportion is carried from our own work. The principle beneath it — that sequencing and microarray detect different classes of change — is Grade A and not disputed.
panel did not include it → or sequencing missed a deletion → “normal” → the search stops → years pass
“Which genes were on that panel, and was a microarray done as well as sequencing?”
Testing has moved fast. A test from a few years ago is not the test available now, and repeating it is not a criticism of anyone.
Some diagnoses describe a pattern of seizures rather than a cause. Doose syndrome is one; Jeavons is another.
These are not wrong, and they are not the end of the road. They are descriptions of what the seizures do. SYNGAP1 is one of the things that can cause that pattern.
So a child can correctly have both labels: the pattern name, and the genetic cause underneath it. Having the first does not mean anybody looked for the second.
“That name describes his seizure pattern. Do we know what is causing the pattern?”
Sleep is often treated as the side issue, to be dealt with once the seizures are sorted. It may be the most reachable part of the whole picture.
Here is the loop, and every arrow in it is ordinary neurology:
poor sleep → seizures come more easily → more seizures → tiredness and poor concentration → less learning → more frustration and harder behaviour → more stress → worse sleep
Read it round again and you end where you started. There is no first cause to find, which is why arguing about which came first goes nowhere.
What matters is which part you can reach. The gene cannot be changed. Sleep sometimes can. And because it is a loop, improving sleep does not only mean a better night — it pushes on the seizure threshold, and on the learning, and on the behaviour.
GRADE B The individual links — sleep and seizure threshold, seizures and cognition — are established. Presenting them as one self-reinforcing loop is this project’s reading, and we are saying so.
“Can we treat the sleep as a real target rather than something to sort out later?”
About half of children respond well to anti-seizure medication. About half do not, and that is called drug-resistant epilepsy. It is a description of what happened, not a verdict on your child or on anybody’s effort.
Seizure type changes which medicine helps. Some drugs that work well for one type can make another type worse. That is exactly why naming the seizure type — and having a genetic cause — changes treatment rather than just satisfying curiosity.
The ketogenic diet is a recognised option where medication has not controlled seizures. It is demanding, it is properly supervised, and it is not a fringe idea.
GRADE A That some anti-seizure drugs worsen particular seizure types, and that the ketogenic diet is used in drug-resistant epilepsy, are both standard.
“Given his seizure types, which medicines are most likely to help — and are any of them likely to make things worse?”
Parents are often told, gently and with real kindness, that the early years are the window and that after them the picture is fixed.
That assumption is being questioned, and it is worth knowing why.
In mice — and we are saying in mice because it matters — restoring SynGAP function in adult animals improved cognition. Not in newborns. In adults, after the supposed window.
GRADE U This is animal work and it has not been shown in people. Mouse findings often do not carry across, and nobody should change what they are doing on the strength of it. We are not telling you there is a treatment. There is not one yet.
What it does mean is that “the window has closed” is a hypothesis rather than a fact — and one with evidence against it. If somebody sets the expectation low, the effort follows the expectation. That is a reason to keep teaching, keep working, and keep expecting.
“Is there any reason to stop working on new skills at his age?”
Read them in any order and you end up where you started. That is not a weakness in the explanation. It is what the thing is.
You are the observer here, and you have watched longer and closer than anyone. These are the questions a good history asks. Answer the ones that matter and skip the rest. What you write stays on your own machine.
When did you first think something was different? Not when somebody agreed with you — when you first thought it. The gap between those two dates is often years, and it is worth saying.
Which way is it going? Over months, not days. Gaining, holding, or losing ground.
What do the episodes actually look like? Describe them as you would to a neighbour. If you have video, that is better than any description.
When do they happen? Time of day, around meals, after poor nights, during illness.
What changed around the same time? Any medicine started, stopped or increased. Any illness. Any change at school.
What have you tried, and what happened? Including what made things worse. That is information, not failure.
What has he stopped doing — and what have you stopped trying? Both halves. The second one is the question nobody asks, and it often says the most.
What worries you most? Not the medical question. The real one.
Number five is the one worth pressing. A genetic answer is not just a label — it changes which medicines are chosen, and it opens research that is closed to children whose cause is unknown.
Not a diagnosis. Nothing here can give you one.
What you have is a specific question with a specific test behind it, and the words to ask it with. This is missed for an ordinary reason: the description fits something commoner, the description gets recorded, and the search stops. You are the only person holding the whole picture, because you are the only one who is there for all of it.
Take one question. Not six.
Grade A here: that delay with epilepsy warrants genetic testing; that sequencing and microarray find different things; that seizure type changes drug choice; that the ketogenic diet is used in drug-resistant epilepsy.
Grade B: the percentages, the deletion proportion, and the sleep loop as one connected circle. Carried from our own work, not re-verified today.
Grade U, and said plainly: the adult-restoration finding is mouse work. It is a reason for hope and a reason to keep expecting. It is not a treatment, and we will not dress it as one.
Why this page exists. It was promised in January 2026, alongside another room that was built. This one was written and then left in a folder. It is here now because somebody asked what else had already been written and never used.
