Dyslexia: What it is, signs, and how to intervene.

Dyslexia is one of the best-known learning difficulties and, at the same time, one of the most misunderstood. When we talk about dyslexia, many people only think about "swapping letters," but the reality is much more complex.

Dyslexia is a specific reading disorder that influences how the brain processes written language, affecting accuracy, fluency, and often writing and spelling.

This article aims to explain, in a clear and accessible way, what dyslexia is, what the main signs are to watch out for, and how to intervene at home, at school, and with specialized support. 

What is dyslexia?

Dyslexia is a specific learning disorder of reading origin, with a neurobiological basis. This means that the brain of a person with dyslexia processes written information differently, making it more difficult to decode words, associate letters with sounds, and automate reading, even when intelligence is adequate and instruction is appropriate.

A child with dyslexia may try very hard, but still read slowly, hesitate, make many mistakes, or avoid reading aloud.

Dyslexia is not laziness or lack of interest. On the contrary, many children with dyslexia feel frustrated because they know they try harder than their peers and yet still have more difficulty.

Simply put, when we talk about dyslexia, we are referring to:

• Persistent difficulty in learning to read as easily as peers.

• Problems in letter-sound (grapheme-phoneme) correspondence.

• Slow, hesitant reading with many errors.

• Persistent spelling errors, even with words that have already been practiced.

Understanding what dyslexia is helps to view these difficulties not as a "lack of ability," but as a learning profile that requires specific strategies and support.

Causes of dyslexia

Research shows that dyslexia is strongly associated with alterations in processing. phonological, That is, in the way a person perceives, distinguishes, and manipulates speech sounds.

In many cases, there is a family history of dyslexia or reading difficulties, indicating a significant genetic component.

Dyslexia is not caused by poor vision, lack of motivation, or deficient teaching, although a poorly structured environment can exacerbate existing difficulties. In dyslexia, there are real differences in how the brain areas linked to reading and language work together.

Some factors frequently associated with dyslexia are:

• Family history of reading difficulties or dyslexia.

• Previous delays in spoken language.

• Early difficulties with rhyming games, dividing words into syllables, or identifying sounds.

Understanding these fundamentals helps reduce guilt and focus on what's essential: creating effective support for the child or young person with dyslexia.

Signs of dyslexia at different ages

Signs of dyslexia can vary depending on age, but there are recurring patterns. Paying attention to these signs facilitates earlier and more effective intervention.

Before school age

Even before a child begins to learn to read, there may be signs that they may develop dyslexia:

• Language delay Oral (starts speaking later or with simpler sentences).

• Difficulty in learning rhymes, songs, and tongue twisters.

• Difficulty in identifying the initial sound of words.

• Problems memorizing simple sequences (days of the week, short series).

At this stage, dyslexia is not yet formally diagnosed, but these signs warrant vigilance and, if necessary, early assessment.

In the early years of schooling

When a child begins formal reading instruction, the signs of dyslexia become more evident:

• Very slow reading, syllable by syllable, with many hesitations.

• Swapping letters with similar shapes or sounds (b/d, p/q, m/n, f/v, etc.).

• Difficulty in consistently associating letters with sounds.

• Frequent spelling errors, even with familiar words.

• Avoidance of reading aloud or resistance to reading tasks.

It is precisely at this stage that identifying dyslexia and intervening can make the biggest difference in the student's academic journey.

At older ages

At the end of the first cycle, in the 2nd and 3rd cycles, and even in secondary school, dyslexia can manifest itself in different ways:

• Functional reading, but slow and tiring.

• Difficulty reading long texts within the expected time.

• Persistence of spelling errors, especially in more complex words.

• Difficulty copying from the board and organizing written texts.

• High levels of fatigue and frustration in tasks that involve a lot of reading.

Even when dyslexia has been partially compensated for, the effort required to keep up with the teaching load remains high.

Dyslexia: what it is not

Understanding dyslexia also involves dispelling some myths. Dyslexia is not:

• Lack of intelligence.

• Laziness or carelessness.

• Lack of attention from parents.

• Simply "swapping letters" or having ugly handwriting.

This clarification is essential so that parents, teachers, and the students themselves understand dyslexia as a specific learning disorder, and not as a character flaw.

Assessment and diagnosis of dyslexia

Given persistent signs of dyslexia, specialized evaluation is essential. Diagnosis is not made solely through observation, but through a set of specific tests, conducted by professionals experienced in reading difficulties.

An assessment for dyslexia typically includes:

• Interview with the family and collection of detailed school records.

• Analysis of global development and language.

• Reading tests (words, pseudowords, texts) and writing tests.

• Tests of phonological awareness (rhyming, segmentation, sound manipulation).

• Observing the strategies used by the child when reading and writing.

To clarify technical terms related to dyslexia and other language and reading disorders, it may be helpful to consult the... Speech therapy glossary.

Dyslexia and other communication disorders

Dyslexia can coexist with other disorders, which makes the picture more complex. In some cases, there is a history of oral language disorders., stuttering or motor speech difficulties.

How to intervene in dyslexia

The good news is that dyslexia can be addressed with specific, evidence-based strategies. Intervention doesn't "cure" dyslexia, but it can significantly reduce the impact of difficulties and allow the person to read and write better, with more confidence.

Intervention for dyslexia should be structured, intensive, and adapted to each student's level. Some general principles include:

• Explicit and systematic teaching of letter-sound relationships.

• Consistent training in phonological awareness.

• Reading practice with graded materials.

• Immediate and targeted feedback.

• Coordination between family, school, and professionals.

The role of speech therapy in dyslexia.

A Speech therapy It plays a central role when dyslexia is linked to weaknesses in spoken language and phonological processing. speech therapist Assesses the linguistic profile and designs an intervention plan focused on the necessary foundations for reading.

In speech therapy, aspects such as the following can be addressed:

• Phonological awareness: rhymes, syllable segmentation, sound identification and manipulation.

• Auditory discrimination of nearby sounds.

• Automation of letter-sound matching.

• Reading syllables, words and pseudowords.

• Strategies for improving reading comprehension.

Content such as the article on speech therapy exercises shows examples of activities that can complement the work done in session, always with professional guidance.

In some cases, it may be helpful to combine in-person sessions with speech therapy follow-up in a digital format, ensuring greater continuity and flexibility of support.

Strategies for supporting dyslexia at home

Parents and caregivers often ask what they can do on a daily basis to help a child with dyslexia. Small gestures, repeated consistently, have an impact.

Some practical strategies include:

• Read together every day, in short sessions, without turning the moment into a test.

• Alternate: the adult reads one part, the child reads another.

• Choose books with larger print, short sentences, and topics that interest the child.

• Emphasize effort and persistence, not just the result.

• Playing with words: rhymes, guessing the initial letter, separating words into syllables.

• To help underline or mark more difficult words for separate practice.

• Avoid making negative comments about mistakes; correct them calmly and constructively.

When in-person access to services is more difficult, combining local intervention with online speech therapy can be an effective way to maintain follow-up.

Strategies for teachers and school

In school, knowledge about dyslexia should translate into concrete practices. Simple adjustments can reduce the impact of dyslexia on academic performance and student self-esteem.

Some pedagogical measures that can help are:

• Allow more time for completing written tests.

• Reduce the number of copies of the chart.

• Allow, whenever possible, a silent reading before reading aloud.

• Use legible handwriting and good contrast in written materials.

• Differentiate the assessment: value the content and reasoning, not just the spelling.

• Offering fact sheets with pre-written keywords to reduce the burden of writing.

Teachers who are informed about dyslexia are able to identify warning signs earlier, refer students for evaluation, and actively collaborate on the intervention plan defined by the professionals.

Dyslexia and emotional impact

Dyslexia doesn't just affect grades. How a child feels about themselves is also profoundly influenced.

When the effort is great and the result falls short, it's common to hear phrases like "I'm stupid," "I can't do it," or "I don't like to read.".

Therefore, any intervention in dyslexia must include attention to emotional well-being:

• Avoid negative labels and comparisons with siblings or peers.

• To value other skills of the child (art, sports, creativity, oral expression).

• To explain, in simple language, what dyslexia is and why it causes reading to occur differently.

• To offer opportunities for success in a variety of tasks, not just reading.

When signs of anxiety, persistent sadness, or school refusal appear, it may also be important to involve psychological support.

Conclusion

Understanding dyslexia is the first step towards acting in an informed and effective way. When we know what dyslexia is, recognize its signs, and know how to intervene, we stop seeing only difficulties and start seeing possibilities.

Dyslexia does not define a child's or adult's intelligence, potential, or future. With appropriate intervention, consistent support through speech therapy, school adaptations, and home strategies, it is possible to improve reading, strengthen confidence, and build a more equitable academic and personal path.

More than labeling, what's important is listening, understanding, and supporting. Every dyslexia story is unique, but all can benefit from quality information, a well-defined intervention plan, and a network of people who believe that learning is possible, even when the path is different.
