Infantile spasms and autism related?

Not always. Infantile spasms are a specific form of seizure seen in infants that will generally be replaced by other seizures as they get older. Though children with autism are more likely to suffer from seizures, not all of them do.
West Syndrome. 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.

Whats the deal with infantile spasms and autism?

Seizures? By "spasms", do you mean seizures? Specifically, when you say "infantile spasms" are you referring to febrile (fever related) seizures, or is this more something you have observed on your own at home. I recommend that you take the child to see his or her primary care provider for clarification.
West Syndrome. Clusters of brief flexor or extensor contractions (spasms) with a distinct eeg pattern; can cause developmental regression. An underlying cause is found in >75%. ~50% have a prenatal/congenital cause like abnormal cortical development, metabolic syndromes. Genetic syndromes. Tuberous sclerosis is a cause that often has autistic symptoms. Also, riskof autism goes up with any brain pathology.

Does anyone know where to find information about infantile spasms and autism?

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.
Doctors. This is a good, but complex question. The best answers should come from your pediatrician or a pediatric neurologist for facts and the proper context.
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 such as 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.
Epilepsy foundation. I would contact the Epilepsy Foundation for information about Infantile Spasms, a particularly serious seizure disorder that effects children during the first year of life. There are also web sites dealing specifically with infantile spasms. The same can be said for autism web sites.

Is there information about infantile spasms causing autism?

Not the spasms. The brain pathology that caused the infantile spasms confers a greater risk of autism, especially if it's tuberous sclerosis. A cause is found in > 75% of cases; almost half have a prenatal cause like abnormal development of the cortex of the brain, metabolic syndromes, or genetic syndromes. West syndrome itself can cause regression or arrest of development. 90% have first spasms before 12 mos.
Cart and horse. It is not infantile spasms that causes autism, it is the brain abnormalities that cause both. Definitions have changed over time. Many children who were previously labeled retarded, are not called on the autism spectrum.

Does anyone know where to find information about infantile spasms causing autism?

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.
