What are the cause of autism?

Not Yet. We know from results of massive amounts of research that immunizations are not the cause.As yet, there are many theories , but nothing remotely proven.
Many Causes, unknown. Dr. Windisch is correct, but wording is very important. Obviously there has to be some cause to autism, as a minority of kids have it. We just don't know what the cause/causes are. 1 current theory is that some people have relatively minor genetic variations that make them more susceptible to insults from infections, allergies, or toxins. Since there is not one autism, there is not one treatment.
No. There almost certainly is not a single cause of autism; but, so far, no one has identified even one. There are plenty of theories including genetic risk, environmental toxins, auto-immune difficulties, and on and one. Some have more backing than others, but no one yet has crafted a compelling hypothesis of exactly what systems go awry with autism and why.

What are the causes of autism or how is it diagnosed to young children?

No known cause. There is currently no known cause. A diagnosis is usually made after a psychiatrist or physician obtains a complete history and physical and bases the diagnosis on specific criteria. Often a test called the ados can provide further information in making the diagnosis. Read more...

Please explain what are the causes of autism and how to heal the disease?

Multiple causes. Most often these are individuals with a genetically based vulnerability, and inadequate biological screeening out of dietary and environmental toxins and deficiecies lead to abn in information processing and if unrecognized the indiv copig strategies lead to behavioral problems. Is need good accurate dx, then support to address information processig pbms, and diet nutritional change and support. Read more...

What's the primary cause for autism or autistic spectrum disorder?

Cause Unknown. Risk factors include genetics, pre-/perinatal factors, neuroanatomical abnormalities, & environmental factors. No single gene can account for autism. There seems to be multiple genes involved. Possibly maternal gestational diabetes, maternal/paternal age over 30, bleeding after first trimester, use of prescription medication during pregnancy, & meconium in the amniotic fluid but not conclusive.

Please advise me. What do you think causes autism?

Multifactoral. Improved recognition is responsible for only part of the increase. Other theories are: our level of exposure to chemicals in our food and environment is thought to be a factor, and our increased consumption of processed food which often lack micronutrients are probably also at play. 1 reference about chemicals: http://www.Mheproducts.Com/autism/pfcs_and_autism.Htm.

Human variability. I suspect it's always been with us but is getting recognized more often. Whether a child is diagnosed as "austistic" or "retarded / learning disabled" varies tremendously place-to-place depending largely on how benefits work, and there's probably a spectrum between severe disability and mild geekiness. None of the "pop" claims have found any real scientific support so far. Read more...
Autism. Truth is we do not know what causes autism. As time goes on pervasive developmental disorder is a spectrum of disorder ranging from mild to what we traditionally thought of as autistic children. The rise in incidence maybe some factor or may simple be our increasing awareness of it. Read more...

What is the main cause for autism and what are symptoms?

Genetics. The main cause of autism is thought to be genetic with environmental injury or toxin. Symptoms are language delay or loss, social incompetence, repetitive stylized behaviors or movements.

No main cause. Autism may have multiple reasons for it's presentation. Genetic, influence of toxins during pregnancy or outside influences. Research is still on going. Main thing - it's NOT the MMR vaccine. The physician who started this fear falsified his research and was disbarred in England. Multiple studies have shown it's not vaccine related.

What is the main cause for autism? What signs should I watch out for?

Autism causes. It is suspected that autism develops from a combination of a genetic predisposition which is triggered by a single or combination of unknown environmental triggers. Thousands of theories are in circulation, but to date none have been indisputably confirmed.

What can cause autism in children?

Antenatal factors . Some syndromes cause autistic spectrum disorder & intellectual disability. Chromosomal microarrays find genetic errors in ~15% of kids with ASD. Maternal low folate (folic acid) levels at conception, rubella, "flu", obesity, advanced age & alcohol/drug use from 3 wks.post-conception-term are some epigenetic factors that alter function, but not structure or sequence, of fetal genes & increase risk of ASD. .

What causes some kids with autism to regress?

Autism's a pervasive. Developmental disorder affecting many aspects of function. It's a challenge for child & family. Anyone may regress to a lower level of function when overwhelmed but a child with autism is more easily overwhelmed by the world even with excellent family & therapeutic support. Regression indicates something is overwhelming the child. Strive to identify the cause while continuing support. Read more...

What causes someone to have autism / asperger's?

Genetic. Leading theories include strong genetic predisposition as we know that autism runs in families. There are twin studies that support this from leading universities. Sometimes "chunks" of DNA are missing, or duplicated. We also know of anatomic brain differences in children on the spectrum versus "neurotypical" kids. The way their "brains are wired" is "different" we are learning. Read more...
