Prevalence of Autism

It is estimated that between 1 in 80 and 1 in 240 with an average of 1 in 110 children in the United States have an ASD. [Read article] 
ASDs are reported to occur in all racial, ethnic, and socioeconomic groups, yet are on average 4 to 5 times more likely to occur in boys than in girls.  However, we need more information on some less studied populations and regions around the world. [Read article]
If 4 million children are born in the United States every year, approximately 36,500 children will eventually be diagnosed with an ASD.  Assuming the prevalence rate has been constant over the past two decades, we can estimate that about 730,000 individuals between the ages of 0 to 21 have an ASD.
Studies in Asia, Europe and North America have identified individuals with an ASD with an approximate prevalence of 0.6% to over 1%.

LONDON (Reuters) - The world's largest genetic scan of people with autism in their families has found that many patients have their own unique pattern of genetic mutations, not necessarily inherited.

The findings published in the journal Nature help confirm the strong role that genes play in autism, and also suggest that small genetic disruptions may begin in the parents' eggs and sperm.

"Our research strongly suggests that this type of rare genetic variation is important and accounts for a significant portion of the genetic basis of autism," said Tony Monaco of the Wellcome Trust Center for Human Genetics at Oxford University, who helped lead the study.

"By identifying the genetic causes of autism, we hope in the future to be able to improve the diagnosis and treatment of this condition which can affect children and their families so severely," he told reporters on a telephone briefing.

A small US study involving toddlers diagnosed with autism, some as as young as 18 months old, showed that intensive early intervention delivered by trained specialists and parents was very effective and improved IQ, social interaction and language ability.

The five year study was based at the University of Washington (UW) Seattle and was led by Dr Geraldine Dawson, who used to be professor of psychology and director of UW's Autism Center, and is now chief science officer of Autism Speaks, an awareness, fundraising, science, and advocacy organization. A paper on the study was published online in the journal Pediatrics on 30 November.

UC Davis M.I.N.D. Institute Study Shows California's Autism Increase Not Due to Better Counting, Diagnosis

January 7, 2009 (SACRAMENTO, Calif.) — A study by researchers at the UC Davis M.I.N.D. Institute has found that the seven- to eight-fold increase in the number children born in California with autism since 1990 cannot be explained by either changes in how the condition is diagnosed or counted — and the trend shows no sign of abating.

Published in the January 2009 issue of the journal Epidemiology, results from the study also suggest that research should shift from genetics to the host of chemicals and infectious microbes in the environment that are likely at the root of changes in the neurodevelopment of California’s children. “It’s time to start looking for the environmental culprits responsible for the remarkable increase in the rate of autism in California,” said UC Davis M.I.N.D. Institute researcher Irva Hertz-Picciotto, a professor of environmental and occupational health and epidemiology and an internationally respected autism researcher.

1.  Behavior is communication.  All behavior occurs for a reason.  It
tells you, even when my words can't, how I perceive what is happening around
me.  Negative behavior interferes with my learning process.  But merely
interrupting these behaviors is not enough; teach me to exchange these
behaviors with proper alternatives so that real learning can flow.
      Start by believing this:  I truly do want to learn to interact
appropriately. No child wants  the negative feedback we get from "bad"
behavior. Negative behavior usually means I am overwhelmed by disordered
sensory systems, cannot communicate my wants or needs or don't understand
what is expected of me.  Look beyond the behavior to find the source of my
resistance.  Keep notes as to what happened immediately before the behavior:
people involved, time of day, activities, settings.  Over time, a pattern
may emerge.

To hear his enemies talk, you might think Paul Offit is the most hated man in America. A pediatrician in Philadelphia, he is the coinventor of a rotavirus vaccine that could save tens of thousands of lives every year. Yet environmental activist Robert F. Kennedy Jr. slams Offit as a “biostitute” who whores for the pharmaceutical industry. Actor Jim Carrey calls him a profiteer and distills the doctor’s attitude toward childhood vaccination down to this chilling mantra: “Grab ‘em and stab ‘em.” Recently, Carrey and his girlfriend, Jenny McCarthy, went on CNN’s Larry King Live and singled out Offit’s vaccine, RotaTeq, as one of many unnecessary vaccines, all administered, they said, for just one reason: “Greed.”
