Hard to say from what you've written.

It is not at all uncommon for children who have autism to have various different types of movements including tics and stereotyped movements. Some children with tic disorders can have problems that may appear to other people as if their eyes are not focused. My son is on autism spectrum and also has another condition that affects movement and a lot of his eye tics involved movement of the actual eye balls, not just his eye lids. Plus he used to "space out" a lot when younger which could have possibly looked like seizure activity to onlookers, but was actually something else altogether.

Some people who have tics can tic in their sleep despite some very old information that's still around online saying that tics are not present in sleep. That old information is not correct.

Not sure what you mean exacly by "She has smell senses, and goes out". Sensory issues are also common in autism however, if she has a sudden disturbance of smell (or taste?) and then passes out, then this has nothing to do with autism or tics.

If this was my child I'd be getting another opinion. If I'm reading your message correctly and the child is in fact passing out then I'd be looking into that as fast as I could. As far as I know, seizures are not uncommon in children on autism spectrum either.

As far as anxiety issues are concerned, that's not uncommon in a lot of these conditions either. I have full blown panic attacks, but have never passed out from one yet, although I have felt as if I was dying. They certainly do affect breathing with hyperventilation though, which in turn affects heart beat and a lot of other things. I even get an aura prior to my anxiety attacks which does heighten my senses... a little like before I get a migraine. In fact some of the sensory activity that I get prior to both has often made me wonder about seizure activity for myself.

I know little from experience about seizure disorders, apart from what I've learned in regard to their association with other conditions in my own family. I would suggest perhaps reposting over on the Epilepsy board here to see if this rings any bells to everyone over there.

As I said, I'd not be putting this down to anxiety or to a movement disorder if she's passing out totally, but I'm not sure if you meant that she is doing that.

Let us know what happens.

I don't know a lot about movement disorders. I get myoclonus jerking, a involuntary jerking of my legs, preventing me from walking. I also cannot stand because my legs unlock and buckle. It is triggered in me by dizziness, and caused from brain stem damages (as far as I can figure out) as a result of an adult onset leukodystrophy. It happens too with people with MS, but is not one of the presenting symptoms. Certain lights will set me off. Looking up for too long will also. The low blood pressure dizziness, when going from sitting to standing will trigger me.
It is something like hiccups. I get those everyday too. But I am sorry I do not know much about movement disorders. What I have is just one of my many symptoms, and I can live it.

I can relate and here to find out more myself, mine started with panic about going out, ocd, that was becoming very strange, moving my hand in a certain way, flapping right arm i couldn't control, slured speech, twitching face, lack of co ordination, long periods of time i can't acount for, then a lump in my throat, that eventually has progressed to having drink in my mouth and not reaisinf i've not swallowed, it takes intense concentration, sometimes my eyelids won't open, sometimes won't close so long period i don't sleep.. Finally i actually had a general seizue in casualty and atlast it was initially taken seriously as i was unconscious for 8 hrs, admitted and put on drips, refered to neurology. They have tried to rule out organic reasons, though i am waiting for EEG and MRI results, i think it is trauma related as i have been through the most traumatic abusive treatment with local services, who don't believe in DID. But i was diagnosed with that at a trauma unit two and a half years ago. No though i have no control over switches, and seem to be in a constant state of terror. I've had infections mainly sinus and respiritory every month for over a year, can't leave the house and cronically tired but can't sleep. What is wrong with me, and why won't anyone do anything, it is so distressing, as i've never had anything like this before, its also frightening for my family, i am trying to research the brain and work out what could be happening, but also would like to know if something like this can happen due to trauma and will i ever function again. I certainly understand your worries and hope that it is not left so long that the symptoms worsen, grateful for any feedback Fractured mind
