Severely neurologically impaired individuals, who manifest islets of remarkable skills in specific areas of interest (e.g., drawing, sculpturing, painting, music, memory feats, arithmetic and calendar calculations), are often identified or described as savants. Initially, the term idiot savant – a French term that means unlearned (idiot) skill (savant) – was first used by down (1887) to describe such individuals with very poor general ability, who were unable to live independently on their own but possessed fantastic abilities in specific areas. An estimated prevalence of savantism in the autistic population is 10 percent, whereas the prevalence in the non-autistic population is less than 1 percent. In this paper, the authors have chosen to delve on the psycho-educational diagnostic evaluation and profiling of a crypto-savant (or hidden savant) boy (YY) with non-verbal low-functioning autism that they have observed, assessed and worked with.
