What is Dyslexia?

Dyslexia is a neurological learning disability that primarily affects reading, spelling, and writing. It is not caused by poor vision, low intelligence, or lack of effort. The brain of a person with dyslexia processes written language differently — particularly in areas responsible for phonological processing (the ability to recognise and manipulate sounds in words).

Crucially, dyslexia has nothing to do with intelligence. Many gifted and highly successful people have dyslexia — including Albert Einstein, Richard Branson, and Agatha Christie.

📊 Key Dyslexia Statistics

Dyslexia affects approximately 15–20% of the population. It is estimated that up to 80% of people with learning disabilities have dyslexia. Early intervention before age 7 is dramatically more effective than intervention started later.

Early Warning Signs of Dyslexia by Age

Signs of dyslexia vary depending on a child's age and stage of development. Here is what to look for at each stage:

Ages 3–4 (Preschool)

Difficulty learning nursery rhymes or rhyming games. Late development of speech. Trouble learning the alphabet. Mispronouncing common words.

Ages 5–6 (Kindergarten)

Difficulty segmenting words into sounds (phonemic awareness). Struggle to match letters to sounds. Reluctance to pick up books. Confusing left from right.

Ages 7–8 (Early School)

Reversing letters like b/d or p/q. Slow, choppy reading aloud. Poor spelling despite effort. Difficulty reading small "sight words" like "the," "was," "said."

Ages 9–12 (Middle School)

Avoidance of reading and writing tasks. Poor writing organisation. Difficulty summarising. Slow reading pace with frequent errors. Poor handwriting.

The Most Common Signs of Dyslexia

Regardless of age, these are the most widely reported signs of dyslexia that teachers and parents notice first:

What Dyslexia Is NOT

Many common misconceptions about dyslexia can delay diagnosis:

Dyslexia vs. Dysgraphia: What's the Difference?

Dyslexia is often confused with dysgraphia, another learning disability that affects writing and fine motor skills. While dyslexia primarily affects reading and phonological processing, dysgraphia affects the physical act of writing — including handwriting, spelling, and expressing thoughts on paper.

The two conditions can co-occur. If your child struggles with both reading and writing, both conditions may be present. A comprehensive screening can identify which difficulties are at play.

When Should You Seek a Dyslexia Screening?

If your child shows 3 or more of the signs listed above, particularly if they persist beyond the typical developmental stage, it is worth seeking a formal screening. The earlier a screening is done, the earlier targeted intervention can begin.

🎯 The Critical Window

Research consistently shows that children who receive dyslexia intervention before age 7 have significantly better long-term reading outcomes than those who begin intervention at 9 or 10. Early screening saves years of struggle.

Frequently Asked Questions

What are the early signs of dyslexia?
Early signs include difficulty rhyming, trouble learning the alphabet, letter reversals (b/d confusion), slow reading, poor spelling, and avoidance of reading tasks. Signs vary by age group.
At what age can dyslexia be detected?
Warning signs can appear as early as ages 3–4. Formal screening is typically most useful from age 5–6 when children begin reading instruction, but can be done at any age.
Is dyslexia related to intelligence?
No. Dyslexia is a neurological difference with no connection to intelligence. Many highly intelligent and successful people throughout history have had dyslexia.
Can dyslexia be cured?
Dyslexia is a lifelong neurological difference and cannot be "cured." However, with appropriate structured literacy interventions, children with dyslexia can develop strong reading skills and thrive academically.
