Introduction
Imagine a child who can read fluently before they can even speak. This remarkable ability, known as hyperlexia, can sometimes be observed in children with autism. Hyperlexia, characterized by an unusually early and rapid development of reading skills, often stands out as a “splinter skill” within the broader context of autism.
“Splinter skills” refer to isolated areas of exceptional ability that may exist alongside significant challenges in other areas of development. In autism, these skills can manifest in various forms, such as exceptional memory, musical talent, or, in the case of hyperlexia, advanced reading abilities.
While these skills can be impressive, it’s important to remember that splinter skills may not always translate into functional abilities in real-world situations. So, while a child with hyperlexia may be able to decode words with remarkable accuracy, this advanced reading ability may not always translate into a deep understanding of the text or the ability to use this skill for social interaction or communication.
Hyperlexia is most common among children with autism spectrum disorder (ASD) – with approximately 6-20% of children with autism demonstrating hyperlexia. [1]
This blog post will explore the fascinating phenomenon of hyperlexia in the context of autism, examining its characteristics and challenges.
The Link Between Autism and Hyperlexia
Studies have shown a strong association between hyperlexia and autism. Research suggests that approximately 84% of children with hyperlexia are also diagnosed with autism. Conversely, about 6 to 14 percent of children with autism are estimated to have hyperlexia. [2]
Autism spectrum disorders (ASDs) are neurodevelopmental disorders associated with atypical brain connectivity. Although language abilities vary widely, they are impaired or atypical in most children with ASDs. The strong link between hyperlexia and autism likely stems from these shared neurodevelopmental underpinnings. Here are some key factors:
Overconnectivity in specific brain regions
Some research suggests that individuals with autism may have atypical brain connectivity, with overconnectivity in certain areas related to visual processing and language. This may contribute to the exceptional visual processing skills often observed in hyperlexia. [3]
Differences in brain regions involved in language processing
Autism can affect the typical development of brain regions crucial for language comprehension and social communication. This may explain why advanced reading skills in hyperlexia are often not accompanied by a deep understanding of the meaning of the text or the ability to use language effectively in social situations.

Hyperlexia: A Red Flag for Autism?
Hyperlexia typically emerges between the ages of 2 and 4, with some children demonstrating advanced reading skills as early as 18 months. However, diagnosing hyperlexia requires careful observation of the child’s overall development over time, as there is no single definitive test.
While the early display of advanced reading skills may initially excite parents, it’s crucial to remain vigilant for potential signs of autism. Children with hyperlexia and autism may exhibit a unique set of characteristics, including:
- Advanced Reading Skills: Early and exceptional reading abilities significantly exceeding age expectations.
- Limited Reading Comprehension: Despite fluent reading, they may struggle to understand the meaning of what they read.
- Social Communication Challenges: Difficulties with social interaction, communication, and understanding social cues are common.
- Repetitive Behaviors and Restricted Interests: Children may exhibit repetitive behaviors and have intense, narrow interests.
- Sensory Sensitivities: Sensory sensitivities to sounds, touch, light, or other stimuli may be present.
Hyperlexia, while impressive, can be a red flag for autism. Early identification and intervention are crucial for children who exhibit both hyperlexia and signs of autism to ensure their optimal development and well-being.

Investigating Folate Deficiency in Children with Hyperlexia
Since approximately 84% of individuals with hyperlexia are also diagnosed with autism, it’s important to recognize that autism can be accompanied by underlying conditions. One such potential factor is folate deficiency.
Folate Receptor Autoantibodies (FRAAs) can interfere with the brain’s ability to utilize folate, a crucial nutrient for brain development, particularly in areas related to cognitive function and neurodevelopment. Therefore, identifying the presence of FRAAs is important, especially in children exhibiting hyperlexia.
The FRAT® test can identify the presence of these autoantibodies. If the test is positive, indicating the presence of FRAAs, alternative folate forms like folinic acid may be considered under the guidance of your child’s healthcare provider.
To understand the impact of FRAT® testing and how it can benefit children with hyperlexia, let’s explore some key facts and a real-life success story.
FRAT® Test - Key Facts To Know
Of the 15,000+ individuals tested with the FRAT® test, a significant percentage showed positive results, indicating the presence of Folate Receptor Autoantibodies. Supplementation with alternative treatments like folinic acid has demonstrated improvements in quality of life for many of these individuals.
A FRAT® user’s TikTok video, sharing her child’s positive transformation following a positive FRAT® test result, went viral. Since its posting, the video has garnered an impressive 800K views, 79K likes, 27K shares, 33K bookmarks, and over 3K comments. Watch the video below:

Over the years, more than 250 physicians have been prescribing the FRAT® Test, underscoring its growing recognition as a valuable diagnostic tool.

Conclusion
Hyperlexia, while an impressive cognitive ability, can sometimes be a red flag for autism. It’s crucial to remember that hyperlexia is often one facet of a broader developmental profile, and it’s essential to address any underlying concerns, such as potential folate deficiencies.
Tools like the FRAT® test can help identify potential folate transport issues, allowing for early intervention and personalized treatment plans. By working closely with healthcare professionals and implementing a comprehensive support plan, parents can help their children with hyperlexia and autism reach their full potential and thrive.
