Prevalence of Autism


The Center for Disease Control (CDC) has estimated in the United States alone, the diagnosis of autism continues to rise. Autism is diagnosed at a greater rate than childhood cancer, juvenile diabetes, and pediatric AIDS combined (DAS, 2010).  According to Autism Speaks, it is estimated that there may be more than 1.5 million individuals with autism.  It is estimated that 1 in 42 are boys and 1 in 189 are girls (CDC). The Center for Disease Control (CDC) estimated that the prevalence rate among males is 4 times higher than females (Quirantes, 2009). The CDC reports that ASD now affects 1 in 54 children.


WHAT CAUSES AUTISM?


The etiology of autism continues to be a mystery. It is often described from a biological perspective and classified as a neurological disorder (Quirantes, 2009). Experts speculate that a combination of genetic and environmental influences has been considered. Currently, through extensive research, the answer to the cause of autism continues to be an idiopathic phenomenon, and science has not yet found the exact cause.


POSSIBLE SIGNS OF AUTISM

  • Limited, absent, and/or avoidance of eye-contact
  • No babbling, vocal sounds, non-verbal, no words or effective communication
  • Loss of previously acquired speech
  • Prefers solitary activities
  • Hyperactivity (very active)
  • Impulsivity (acting without thinking)
  • Aggression and Meltdowns may be due to absent speech or communication
  • Causing self-injury
  • Unusual eating and sleeping habits
  • Lack of fear or more fear than expected

  • Sensitive to sounds, textures, lights, colors, smells, and food.
  • Difficulty understanding, or showing understanding, or one's own or other people’s feelings 
  • Avoid or resist physical contacts such as hugs, holding hands, or sensitivity to touch

"STIMMING"


Stim or Stimming is best described as self-stimulatory behavior and is sometimes also called, "stereotypic" behavior that a child with autism is often observed to engage in and may include repeating words, songs, or phrases. 
As autism is a spectrum disorder, not all children diagnosed with autism will display the same symptoms.
