According to Sally Saywitz M.D., co-director of the Yale Center for Dyslexia & Creativity and author of the best-selling book Overcoming Dyslexia:
“Dyslexia is an unexpected difficulty in reading for an individual who has the intelligence to be a much better reader. It is most commonly due to a difficulty in phonological processing (the appreciation of individual sounds of spoken language), which affects the ability of an individual to speak, read, spell and often, learn a second language (1).”
For example, it may take an individual with dyslexia multiple steps to read something, when it only takes someone without the disorder one step to read it.
Therefore, the first step in the multi-step reading process of dyslexics is connection. In other words, the first step involves helping the brain identify letters and connect them to sounds. The second step involves organizing the sounds (i.e. putting them in the right order). The third step involves forming sentences, then paragraphs, and making sure they are clear, cohesive, and constructive.(1)
Keep in mind that both dyslexic children and adults have problems matching the letters to the correct sounds that the letters make.

Dyslexia is the most common learning disability, representing approximately 85% of those with learning disabilities. (1)
Estimates vary, however approximately one-in-five people suffer from the condition.(1) In addition, even though both boys and girls experience dyslexia, boys tend to be diagnosed earlier than their female counterparts – partly because of behavioral problems commonly associated with dyslexia. It is important to note that dyslexia can occur alone or in combination with other learning disabilities.
This condition tends to run in families. In fact, approximately 40% of siblings have dyslexia (i.e. reading issues) and approximately 49% of parents with dyslexic children also have reading problems. Therefore, researchers have suggested that a number of genes are linked to this condition.(3)
A common myth linked to dyslexia is that people with this condition tend to write their letters and words backwards. The truth is, while dyslexics do tend to write letters and words backwards, so do “healthy” young children – especially when first learning to write. In fact, writing letters and words in reverse is not the most common sign or symptom of dyslexia.(1)
Although the signs and symptoms of dyslexia are based on the individual, some characteristics have been linked to the condition.
Listed below are common signs and symptoms of dyslexia:(2)
• A family history of reading and/or spelling difficulties
• An inability to recognize rhyming patterns like: cat, bat & rat

Here is a helpful video that can help you better understand what triggers this condition:
Several learning conditions can concur (co-exist) with dyslexia. Some of these conditions may even resemble dyslexia.
Listed below are other conditions that can co-exist with dyslexia (3):
• ADHD: Approximately 40% of people with attention deficit hyperactivity disorder (ADHD) have dyslexia. People with ADHD tend to have a hard time staying focused while reading. Conversely, people with dyslexia can appear to have problems focusing while reading, when in reality they are grappling with dyslexia – not ADHD.
• Executive Functioning Disorders (EFD): “Executive functioning” refers to flexible thinking, organization, and working memory.
• Slow Processing Speed Conditions (SPS): Slow processing conditions can make it hard to master basic reading skills. Slow processing speed refers to a slower speed of “processing” – i.e. receiving information, analyzing it, and crafting a response to it.
• Auditory Processing Disorders (APD): Auditory processing disorders can affect what a person actually hears. In fact, children with APD tend to have a hard time recognizing different letter sounds and sounding out new words.
• Visual Processing Disorders (VPD): Visual processing disorders can affect what a person actually sees on the page (i.e. words and letters). In other words, words may appear blurry on the page or jump off the page.
• Dysgraphia: Dysgraphia occurs when a person has a hard time writing letters and numbers. In addition, some words may also be difficult to spell.
• Dyscalculia: Dyscalculia occurs when a person has a hard time writing numbers and working math problems.
Brain imaging studies (i.e. functional MRI and PET scans) identify differences between people with and without dyslexia. It is important to note that multiple regions in the brain are responsible for reading.
In addition, the term “neuroplasticity” refers to the concept that the brain is capable of changing. In fact, according to researchers, the brain activity of people with dyslexia can change once they receive proper tutoring.
Here is a helpful video that can help you better understand the relationship between dyslexia and the brain:
A series of tests administered by a reading specialist, clinical psychologist, school psychologist and/or neuropsychologist are used to diagnosis dyslexia. A comprehensive evaluation is used to determine the individual’s strengths and weaknesses. It is also used to identify other learning disorders.
First, the professionals take an in-depth medical and family history, notating previous and/or current learning difficulties. If the individual is a child, the professionals will also examine his/her school reports provided by his/her teacher. (3)
Note: School psychologist can also provide formal evaluations for a child. This can be initiated by providing a written request to school administrators or the child’s principal. School-based exams are free. But, as an alternative, there are private evaluators who charge for their services.
Once the child is tested, an individualized education plan (IEP) or 504 plan may be initiated. This IEP or 504 plan may include specialized reading services and/or classroom accommodations.
Here are helpful videos that can help you better understand the evaluation process:
It is important to understand that dyslexia is not a vision problem. Therefore, treatment should not involve eye exercises, vision therapy, tinted lenses, or filters.(5) Rather, the proper treatment should involve learning tools that help decode words and phonics, along with classroom accommodations.
One treatment that can be beneficial for dyslexics is the Orton-Gillingham (OG) technique. The Orton-Gillingham technique is a gold standard dyslexia treatment that involves a multisensory, structured language education (MSLE) intervention. This technique is commonly used by reading specialists, speech-language professionals, and special education teachers to combat learning disorders like dyslexia.
For example, this technique may involve using sandpaper letters to help a person with dyslexia learn phonics.
Or it may involve learning syllables by tapping them out with fingers.
MSLE also includes “over-learning” or learning through repetition.(4)
Classroom accommodations may include: having more time to take tests, having copies of teacher’s notes, having a special seating arrangement, having assisted reading technology (text to speech software or audiobooks), having a classroom attendant, and more.(4)
Below is a helpful video that can help you better understand the Orton-Gillingham technique:
There is no cure for dyslexia. It is a lifelong condition. However, early intervention with a reading specialist can improve one’s understanding of the written language, and thus facilitate learning. In addition, classroom accommodations can help those with this condition.
