Dyslexia is a complex neurological disorder where the individual has varying degrees of difficulty in processing information. Studies show that the dyslexic brain processes and adapts to information at a rate half of the normal brain. Everyday examples of information would be objects, sounds and peoples’ voices.
MRI’s now show how a brain responds meaning earlier diagnosis.
Professor John Gabrieli of MIT suggests that this shows a decreased plasticity, or ability to learn new things, in the dyslexic human brain. Gabrieli conducted an MRI experiment on young individuals who were both normal and dyslexic, and found that the dyslexic showed a significant difference in cranial response when hearing multiple voices as opposed to only one voice.
It’s a difference in the brain that’s not about reading per se, but it’s a difference in perceptual learning that’s pretty broad,” Gabrieli added.

Key takeaways
- Those with dyslexia, the brain have the inability to understand to repeated input which is known as neural adaptation.
- People with dyslexic’s brain activity remains high while listening to a consistent voice and not to multiple voices, showing they did not assimilate well with change.
- Researchers are beginning to believe that dyslexia affects the entire brain and not only the learning portion.

Is your child struggling in school?
Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
