Massia Bailey | Demystifying dyslexia: Understanding the learning difference behind the label

INCREASED PREVALENCE RATES

Approximately one in five students struggles with dyslexia, yet many misconceptions persist. Dyslexia is a subtype of neurodivergence that has shown increased prevalence rates over the last decade. According to the International Dyslexia Association, dyslexia is a common learning disability or neurodevelopmental condition that affects how the brain processes written and spoken language — particularly in areas such as reading, spelling, and sound processing.

Estimates of its prevalence vary. Some studies suggest that approximately three to seven per cent of a school population may demonstrate significant reading and writing difficulties when strict diagnostic criteria are applied. However, broader indicators suggest that as many as 15–20 per cent of individuals may exhibit some symptoms of dyslexia, including slow or inaccurate reading, disfluency, poor spelling, or confusion of similar-looking words.

DIFFERENTIATING BETWEEN DYSLEXIA AND GENERAL READING DIFFICULTIES

Given the increased recognition of dyslexia, it is essential that general reading difficulties are not misdiagnosed as dyslexia. Understanding this distinction is critical for providing appropriate supports and interventions to the learner. Reading difficulties associated with dyslexia typically stem from challenges in phonological processing. Phonological processing is the ability to manipulate the sound structure of language. These challenges are considered unexpected when compared to an individual’s general intelligence. A common method of identifying dyslexia is the ‘discrepancy model’, which reveals a notable gap between a student’s intelligence and reading achievement. Learners with dyslexia often demonstrate average to above-average intelligence, yet struggle to read and write at a level consistent with their cognitive capacity.

In contrast, general reading difficulties may result from external or instructional factors. These may include limited early exposure to reading, ineffective or insufficient instruction, socio-economic disadvantages, English language acquisition challenges (e.g., Creole interference), or cognitive impairments unrelated to phonological processing, such as those resulting from traumatic brain injury. Unlike dyslexia, general reading difficulties can often improve significantly with targeted and consistent instruction.

DEBUNKING MISCONCEPTIONS SURROUNDING DYSLEXIA

Misconception 1: Dyslexia means seeing or reading words backwards

Dyslexia is not a visual disorder. While letter reversals, such as confusing ‘b’ and ‘d’, or ‘p’ and ‘q’, may occur, these are also common among early readers without dyslexia. The primary difficulty lies in phonological processing – identifying and manipulating the sounds of spoken and written language – which impacts decoding, spelling, fluency, and comprehension. Although some individuals may experience visual stress (e.g., words appearing to move on the page), the root cause of dyslexia is neurological, not optical.

Misconception 2: Dyslexia is a sign of low intelligence or laziness

This is a harmful and inaccurate misconception. Dyslexia is unrelated to intelligence or motivation. Many individuals with dyslexia have average or above-average IQ scores and often exert greater effort than their peers to read and learn. Some demonstrate strengths in problem-solving, creativity, and spatial reasoning. Prominent individuals such as Whoopi Goldberg and Richard Branson exemplify how dyslexia affects how someone learns, not how intelligent or driven they are.

Misconception 3: Dyslexia is not real – it is just an excuse

Dyslexia is widely recognised by major educational, psychological, and medical organisations, including the American Psychological Association and the International Dyslexia Association. Research has shown that dyslexia has a strong genetic and neurological foundation. Family histories often include learning differences or related neurodivergent profiles. Brain imaging studies have further confirmed distinct patterns of activation in individuals with dyslexia, particularly in areas responsible for phonological processing.

Misconception 4: Dyslexia only affects English speakers

Dyslexia occurs across all languages and writing systems. While it may manifest differently depending on the complexity of a language’s phonetic structure, dyslexia is not language-specific. Children learning any language can be affected.

Misconception 5: Dyslexia cannot be diagnosed before third grade

Although many students are not formally identified until later, signs of dyslexia can be observed as early as the preschool level. Difficulties with letter recognition, rhyming, and word retrieval may indicate risk. Early screening and intervention greatly improve outcomes.

CO-OCCURRING CONDITIONS AND BROADER IMPACT

Reading challenges are a hallmark of dyslexia, but the condition may also affect spelling, written expression, working memory, and executive function skills such as time management and organisation. Many students struggle with word retrieval, following multi-step directions, or sequencing tasks. Dyslexia often co-occurs with other conditions, such as attention deficit hyperactivity disorder, which may further impact learning through inattention, impulsivity, or hyperactivity. Additionally, some students with dyslexia experience auditory or sensory processing difficulties, including heightened sensitivity to sound, touch, or smell – factors that can further interfere with reading development and classroom functioning.

INTERVENTION FOR DYSLEXIA

Dyslexia is not a condition that can be ‘fixed’ with extra reading practice alone. Because it is a lifelong neurological difference, individuals with dyslexia require reading instruction that is specifically designed to meet their needs. The first step is diagnostic testing to identify specific areas of deficit. Research supports the use of structured literacy –an instructional approach that is explicit, systematic, sequential, and multisensory. This method has yielded positive outcomes for students with dyslexia. In addition, assistive technologies such as text-to-speech and speech-to-text tools can be used to scaffold learning and enhance access to other curriculum areas.

EMOTIONAL SUPPORT

Academic intervention is essential for students with dyslexia – but emotional support is just as critical. A child who constantly struggles to read may begin to internalise feelings of failure, frustration, or shame. Both teachers and parents can foster resilience and self-confidence. Teachers can create a classroom culture that values effort over perfection. Allow the student to volunteer, and never equate reading ability with intelligence. Reinforce that reading does not define their potential. Parents can offer that many successful people share the same challenge. Reading aloud together and focusing on their strengths can reinforce a positive self-image.
