Asperger’s syndrome (AS), was historically considered a distinct high-functioning subtype of autism, but is now considered simply an autism spectrum disorder (ASD) following a change to the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 2013. (Kite,2013)

Because AS was entered into the DSM-IV only 22 years ago, the total number of affected individuals remains difficult to specify. Recent results from the National Institute of Child Health and Mental Development estimate that 1/500 people (0.2% of the general population) have some form of AS (Autism/Asperger Network). In terms of autism (ASD) in general, it is important to note that the most commonly reported measure of frequency is not incidence, but prevalence, because the disorder begins long before diagnosis, and that time interval is influenced by a wide range of factors (Newschaffer,2007). The overall prevalence of ASD worldwide (including AS) is 7.6/1000, or 1 in 132 persons (Baxter,2015). The overall prevalence of ASD in the U.S. (including AS) is far greater at 14.7/1000, or 1 in 68 children aged 8 years (Baio/CDC ADDM Network).

ASD has been reported in all racial, ethnic, and socioeconomic groups. ASD is almost 5 times more common among boys (1 in 42) than girls (1 in 189) (Baio/CDC ADDM Network). Nearly half (46%) of children with ASD have average to above average intellectual ability (IQ>85) (Baio). In some cases, IQ may be very high, even in the genius range (Asperger 'sNormalIQ, 2010).
