Hyperlexia is when a child starts reading early and surprisingly beyond their expected ability, sometimes when they are 18 or 24 months, and occasionally it is not a stand-alone diagnosis. In this post, find out what hyperlexia is, what are the symptoms, what are the different types, how it is diagnosed and if you share some of the traits.
There are three different types of hyperlexia:
Experts disagree about how common hyperlexia is, but it is believed that around 6% to 14% of autistic kids are considered hyperlexic. In addition, the causes of hyperlexia remain unknown, yet it might be related to a different neurological brain organisation from the neurotypical one.
Depending on the type of hyperlexia, the diagnosis may vary. Hyperlexia 1 does not need to be diagnosed as it is not a disorder, but more a kind of child superpower.
On the other hand, a diagnosis is needed for hyperlexia 2 and 3, but there is no specific test. As happens with other neurodivergent conditions or traits, the diagnosis is based on the symptoms children show and develop.
A first step can be doing our online hyperlexia test, but remember this is not an official diagnosis but an indicator.
Nat Hawley, our Head of Community, has hosted a webinar about hyperlexia. The webinar explains the signs of hyperlexia. It is not intended to diagnose hyperlexia – only a qualified medical professional can make a diagnosis.
