Autism Spectrum Disorder
Autism Spectrum Disorder- Better Diagnosis or growing epidemic?
Is there a growing epidemic of Autism Spectrum Disorder, or is modern medicine better diagnosing the disorder? This seems to be a current debate in the question “Why do we now see so many diagnosed cases of autism?” Current incidence of Autism Spectrum Disorder, or ASD is unbelievably 1 out of every 150 children. As compared with the number of children diagnosed with this disorder in 1980, the percentage of ASD has quadrupled. In 1980, autism was considered a rare disorder, with an estimated 2-5 per 10,000 people.
♦ Autism is generally diagnosed during a child’s first 3 years of life, however new research is now identifies diagnostic indicators as early as 6 months.
♦ In their 1999 report entitled ‘Changes in the Population of Persons with Autism and Pervasive Developmental Disorders in California’s Developmental Services System: 1987 through 1998’, the California Department of Developmental Services reported a 273% increase in DSM-IV full-criteria autism cases enrolled in their program during that 10 year period of time.
♦ Currently 1 in every 150 children will be diagnosed with autism. The table below demonstrates the escalating diagnosed cases of autism when compared with other childhood disabilities.

One may wonder what is happening to cause such a dramatic increase in this relatively new disability. A review of medical, professional, and research literature will result in an array of various explanations. An extensive review of the medical, professional, and autism interest group literature results in a wide diversity of opinion and explanation to the apparent escalating rise of autism.
♦ One will find an extreme pivotal range from the most traditional and conservative to the most transitional and holistic of theory.
♦ There are the ones that state that autism has no cure, while others claim that there is a complete and definite cure.
♦ Trying to formulate one’s own concrete opinion, given the variety of theories, can be quite mind-boggling.
♦ During the 1970’s, research data began to be reported which showed strong evidence in the role of genetics in the causation of autism.
♦ The theory of environmental influence in the causation of autism has only recently taken a more prominent stance amongst the professional and medical communities.
♦ In his book Changing the Course of Autism, Dr. Bryan Jepson states that even though finding the gene that triggers autism could lead to developing a medication for treatment, “understanding the role of the environment and studying the biochemistry of autistic children seems much more likely to lead to effective treatment immediately, and in fact would pinpoint which genes should be targeted…understanding the genetic factors requires understanding the impact of the environment on the genetic code.”
♦ Most proponents of this theory do believe that there is a genetic predisposition to autism, however that changes in the environment and in the practice of modern day medicine are “activating”, you might say, the genetic flaw.
As a Speech/Language Pathologist of 25 years, I have noted an unprecedented increase in the diagnosis of autism or one of the various diagnostic labels that fall within the autism spectrum of disorders among the pediatric client population I work. The “picture” of the typical autistic child has made dramatic and wide range changes in the years since beginning in the field of speech and language therapy. The profile of a regular classroom has been transformed in the past 20 years. School nurses are inundated with various medications from those for ADD/ADHD to Bipolar Disorder to ASD. So, are we experiencing an epidemic of Autism Spectrum Disorders or are we just getting better in diagnosing it? Regardless of the causation, the autistic child can be helped! New technology and integrative techniques are available to assist in better brain networking and the overall abilities for the autistic child to understand his or her world.
