Autism isn't more likely in a smoking pregnancy. Autism is a neurological difference, just like with any other biological variation it comes down to genetics.
Men. a.k.a. young boys
It is unlikely that your child would have autism. There is a genetic component to autism, so it is more likely that you would have a child with autism than a couple with no history of autism in their backgrounds. However, it is still more likely that your child will not have autism than have autism.
There are about an equal number of boys and girls who are diagnosed with severe cases of autism, but more boys than girls are diagnosed with moderate and mild cases of autism. It has not been determined whether this is because fewer girls have autism or because they are less likely to be diagnosed.
Autism isn't something you 'get' you are born autistic - anyone can be born autistic, although there does seem to be a gentic link so often autistic people are more likely to have autistic children, or you often see multiple siblings in a single family with autism. As yet we don't know what causes autism, so we can't tell who is more likely to have autistic offspring.
No, Autism doesn't make you lose your hair - how could it? Autism is a neurological variation, it's no more likely to cause hair loss than any other neurological variation.
There is no direct evidence linking smoking during pregnancy to Gray Matter Heterotopia. However, smoking during pregnancy has been associated with various adverse effects on fetal brain development and overall health. More research is needed to determine any potential links between smoking during pregnancy and Gray Matter Heterotopia.
Yes, it is possible. In one study, the chance that an identical twin has autism when the other does is 82%. That means that 18% of the identical twins did not have autism. It is much more likely that an identical twin will have autism if the other does than that a fraternal twin or other sibling will, but it does not happen every time.
The following numbers are approximations since different studies have found slightly different results. The chance of having one child with autism might be as high as 1 in 100. After having one child with autism, the chance of having a second child with autism is 1 in 20. After having two children with autism, the chance of having a third child with autism is 1 in 3.
No
Not very likely. Nosebleed is extremely rarely a sign of pregnancy. Nosebleed can however be much more likely a sign of allergies rather then pregnancy.
More than likely
yes
