What is Hyperlexia Disorder?

Some say hyperlexia is a type of autism. Some say hyperlexia is it's own unique disorder and should not be placed under the "A" umbrella. Regardless, it is a developmental disorder manifesting in the remarkable ability of very young children to read. Hyperlexic children are typically fascinated by letters and will often recite letter names as their first words. All of this would be fine if it were not for the varying degrees of limitations in social and communicative abilities that so commonly accompany this amazing skill. It is this similarity to some autistic traits that leads some to believe that it's just a form of autism.
