How does Tuberoous Scroloses cause autism?
You a few people on the spectrum have Tuberous Scroloses (TS)? Is the TS that they have just a co-morbid, just something which just comes with the autism, like epilepsy, ADHD, LD's, etc, or is it actually a specific cause of autism. If it is then how does TS cause autism? And what is the link between TS & Autism?
actually, almost all the other conditions you listed are seperate of autism, although they are often co-morbids, it is not needed
About 50% of people with TS have autism. I know it's a seperate condition, but autism is still very common in TS & I want to know if it's the TS that's the co-morbid of the autism, or if it's the TS that causes the autism, when they come together. And I most of the other conitions I mentioned were seperate too, but they still often come with autism.
Where did you hear this? I think you're wrong about that.
I checked the wiki on TB, there was no mention of autism. A google search of autism and TB brought a few studies possibly linking a mother having TB to her child having an increased chance of a mental disability, including autism. Also there were some studies about a TB drug being tested as a possible treatment for autistic kids. But I found nothing like what you said. So please find something and link it here.

This quote from the TSC Association UK:
So by applying very basic maths (even that I can do!) then technically yes it is about 50%. I know someone who has TSC with AS (They put the C on to stop the confusion with Tourette syndrome). I think you are at a 50-50 risk of having an ASD with TSC but having an ASD doesn't make you more likely to have TSC.
Sorry if that was a load of pointless babble...
And here's a link to their website:

Just in case you are interested

Thanks for your help. So, when TSC comes with autism; is it a cause of it, or is just something which just comes with it, but we don't know why; like autism & epliepsy? Except of course, epilepsy's far more common in autism, as there aren't many ASD people who have TS even though there are a lot of TSC people who are autistic. But TSC is quite a rare condition.
Tuberous Sclerosis has a frequency of 1 out of 20,000 people. Autistic Spectrum Disorders amongst those with Tuberous Sclerosis is 43%-86% in epidemiological studies.
I discovered this because my Shagreen Patches have again been irritated by something, along with subungual fibromas disrupting my toe nail anatomy. I also have epilepsy, and epilepsy happens in 78% of cases of Tuberous Sclerosis. I have genetic dental problems that are also very common with Tuberous Sclerosis. My very large, and unusual type, of Becker's Nevus is not suppose to be related to Tuberous Sclerosis, but many types of nevi are. If these readily apparent impairments were independent of each other, the chances that I would have them would be about one out of a few hundred million, while having them as a result of Tuberous Sclerois would be about one out of thirty thousand. Money stops me from getting genetic testing for Tuberous Sclerosis and genetic disorders possibly independent of it (such has genetic hypodontia, other nevi tuberous disorders, LQTS-2, etc.).
Whether Autism is associated from the epilepsy, or directly from the sclerosis (which may have "caused" everything else) "remains to be examined".

If I have Tuberous Sclerosis, the epilepsy is the most disruptive, the autism is more of Asperger's, the heart conditions more like LQTS-2, with minor to moderate liver, kidney, skin, dental, and digestive problems from other possible "tubers" in fluctuating disruptions.
Much confusion results from the "a priori" nature of DSM disorders, versus the much more empirical base for nearly exclusive physical disorders often with strong correlations to DSM disorders.

It does in some cases. Autism isn't caused by one thing but by many different things. And there are a number of brain areas that, if damaged, result in specific kinds of autistic behavior. Such as frontal lobe damage causing perseveration and executive dysfunction, or right-hemisphere damage causing difficulty understanding nonverbal cues and tone of voice (NVLD is often caused by right-hemisphere brain damage) or so forth. Damage to enough of those areas would cause someone to meet the criteria for an autism spectrum condition, and if the damage happened early enough they'd meet the onset criteria too.
Brain damage can even cause strengths. People with frontotemporal dementia (where the frontal lobes and tempioral lobes progressively degenerate) sometimes develop artistic or other creative talents at a certain stage in the condition, because lack of inhibition means they no longer suppress irrelevant ideas and so those ideas turn into creative inspiration.
