How common is autism?

, How common is autism?Latest reports indicate that prevalence of autism is approximately 1-2 per 1,000 children and prevalence of ASDs (Autism Spectrum Disorders) at approximately 6 per 1,000 children. The ASDs include, autism (1-2 per thousand), PPP-NOS or Pervasive Developmental Disorder-Not Otherwise Specified (3.7 per 1,000) and Asperger Syndrome (0.6 per 1,000). But this data is not accurate and the true prevalence of autism and ASDs may be much higher. There has been sharp increase in autism and ASDs from 1990s to 2000s, most likely due to change in diagnostic criteria, public awareness, age at diagnosis, availability of services, referral patterns etc. However, the role of unknown environmental factors also can not be ruled out.

Currently available evidence suggest that, there is true increase in prevalence of autism, and the increase in prevalence is not merely due to public awareness, change in diagnostic criteria, availability of service etc. as previously thought, which indicate the presence of unidentified environmental factors, which need to be identified. To identify the unknown environmental factors responsible for increase in autism prevalence, we need to focus the research and funding towards identifying the causes of autism, other than genetics.

There is a sex difference in prevalence of autism and boys are at higher risk in compare to girls. The sex ratio of ASDs is 4.3:1 for boys: girls. The prevalence of ASDs is same in all socioeconomic classes, races and ethnic groups.

Children suffering from autism or ASDs are at higher risk of certain medical problems such as:

  • Mental retardation: 25% to 70% of children with autism have some degree of mental retardation. But for children with ASDs, without autism, the mental retardation is lower.
  • Genetic disorders: approximately 10-15% of children with autism have some genetic disorder, such as Mendelian disorder, chromosomal disorder etc.
  • Epilepsy: the risk of epilepsy in autistic children is higher than normal children.
  • Anxiety disorders: autistic children have higher incidence of anxiety disorders.

Autism is not an uncommon disorder of metal and social developmental problem among children. Do not ignore autistic children and manage them well, so that they can adjust in society and live productive life.
