Abstract

Autism, like a number of other challenging conditions, is impressive by the multiple theories of aetiological explanation in the face of a concrete universally accepted Up till the 1970’s it was being wrongly labelled as childhood schizophrenia. Since then, much ground has been covered both by researchers and the condition itself, which according to the National Disease Control centres, effects 1 in 42 boys and 1 in 89 girls. In 2013, the American Psychiatric Association merged four previously distinct diagnoses into one umbrella diagnosis of autism spectrum disorder (ASD). These included autistic disorder, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDDNOS) and Asperger syndrome. Some disregard the Spectrum altogether. These are but a tiny fraction of evidence exhibition the flux of uncertainty in the very perception of the condition.
