Not correct: Infantile spasms will not cause autism. Infantile spasms are usually the result of an underlying brain abnormally, which may result in autism like symptoms.

There is another neurological condition call Landau-Klefner syndrome that also has some features that can look like autism. Although as many as 1/3 of children with autism may have seizure problems, no evidence suggests that seizures are an underlying cause of autism--rather that the brains children with autism are vulnerable to seizures.

It's not the spasms: Any brain pathology causes greater risk of autism. Underlying causes are found in > 75% of infants with west syndrome. Almost 50% of infants with ws have a prenatal cause like abnormal development of the cortex of the brain, metabolic syndromes, or genetic syndromes. Tuberous sclerosis can cause both west syndrome & autism. West syndrome itself can cause regression or arrest of development.

Some connection: Not clear that there is a causal link. Here's a link to an abstract of a study: http://www.Ncbi.Nlm.Nih.Gov/pubmed/18557779 risk of autism increased with those with infantile spasm, but risk of seizures is increased with autism. The grea majority of children with autism don't have infantile spasms, and vice versa. Co-occurrence may reflect an underlying problem with brain development.
