Abstract
BACKGROUND: Hyperlexia is defined by a precocious and spontaneously acquired ability to read at preschool age. Hyperlexia appears to be a wide yet not highly studied phenomenon involving different populations and possibly including children with different neuropsychological profiles and outcomes.METHODS: we describe two clinical cases of unrelated children diagnosed with Autism Spectrum Disorder (ASD) who both showed precocious and spontaneous reading ability. We report the neuropsychological assessment they underwent. RESULTS: Both children showed above average IQ, reading skills, and text comprehension, whereas one showed below average comprehension only in oral text. We question whether these two phenotypes can be considered forms of hyperlexia, as defined by the most recent and consistent observations, or a subtype of ASD. CONCLUSION: We conclude that our patients should be considered hyperlexic, with interesting potential implications for prognosis and rehabilitation.
