Understanding Dyslexia

Updated: Apr 27


Although dyslexia is often believed to occur due to a vision disorder, it is actually a language-based learning disability that is caused by neurological processing differences. Dyslexia is the most common learning disability among children in the US, and is made up of a collection of symptoms such as challenges with reading, writing, spelling, and word pronunciation. Individuals with dyslexia can also have trouble with spoken word and find it difficult to express their thoughts accurately and comprehend what others tell them. Those with dyslexia struggle connecting letters or a collection of letters to the sounds they make, due to different processing in the brain. Challenges at this step makes it much more difficult for those with dyslexia to complete the other steps needed for reading, writing, and speaking. Dyslexia most commonly presents throughout childhood and into adulthood through difficulty with reading, however, it is important to note that most people with dyslexia have average or above average intelligence, as dyslexia is not tied to IQ.




The Massachusetts Dyslexia Guidelines created by the Massachusetts Department of Elementary and Secondary Education defines dyslexia as:

“Dyslexia is a specific learning disability that is neurobiological in origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities and the provision of effective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge.”


Although dyslexia cannot be cured, intervention can provide systematic instruction to allow those with dyslexia to read and write successfully, increasing their self-esteem, allowing them to thrive in school, work and home.


Dyslexia can present differently at different stages of development. If you suspect that a family member, friend, student, or that you yourself may have dyslexia here are some typical signs at different ages to look out for:
