Which vaccines for infants, toddlers, to prevent childhood illnesses cause autism because of the mercury in it?

Q: I was just curious and wonder which vaccines that are given to babies and infants, to prevent childhood diseases and illnesses cause autism? Will this new vaccine for H1N1 make autism worse? My son has PDD autism NOS on the mild form and it makes me wonder. Could have been before 14 months (the age ADHD was obvious) or close to 2 years old when autism was first suspected. If it was caused from a shot and was preventable that is pretty sad and makes me annoyed.

A: I think it is interesting that autism is on the rise. At first, the professionals said that they were simply diagnosing it, better. Now, they say there is truly a rise in the incidents.

Read, google, etc. Look up natural treatments, but be careful of those who are out to market books, online. Look in bookstores, rather than online books. Some people have mentioned gluten and wheat products. Some have connected mercury, wheat, and candida. Look it all up, and see what you think. Do an elimination diet.

A: Functional defects can affect the nervous system, immune system, reproductive system, endocrine system, or other systems of the body, and may not become apparent for months or years. These may include, for example, mental retardation, autism, attention deficit hyperactivity disorder (ADHD), some types of blindness and deafness, some immunological problems, and some degenerative disorders. AD/HD is a disorder that makes it hard for children to sit still, control their behavior, and pay attention. It is usually diagnosed before the age of 7, but not always. Doctors aren’t sure what causes AD/HD, but studies support the theory that it is related to an imbalance of certain chemicals in the brain called neurotransmitters.
