The cause of autism is very controversial. They should be regarded not as an established fact, but as a theory and probability. However, do not overlook them due to lack of evidence; it simply is not possible to test them. 

Toxic heavy metals such as lead and mercury are highly toxic to live and are known to cause developmental defects. Exposure to these elements may have contributed to your child's autism. You can get more information about heavy metal testing via online sources.

Lead is a potent killer of brain cells (neurotoxin). Even short-term exposure to small amounts led by the fetus, infants, or children can cause permanent learning disabilities, attention deficit disorder, and reduced intelligence.

Banned lead paint and gasoline in the 1970s, but is still a serious threat through the contaminated soil, pipes, old painted surfaces, vinyl mini-blinds, and lead in toys. 

Leading poses are a serious threat to all children, but it may be much more devastating in children with a genetic or biochemical predisposition to autism because the path to rid the body of toxic heavy metals such as lead and mercury is often seriously flawed and ineffective in children. 

High lead may appear in your blood mineral tests and can provide your child with the help of a doctor. If it's higher than average or if you live in a house built in the 1960s or earlier, you should buy home lead testing kits.
