Dyslexia / dysorthographia

Although dyslexia or reading difficulties appear at the begin of school, their impact can be seen throughout school years in all subjects.

Dyslexia, usually paired with dysorthographia, is also called a written language disorder.

It consists of persistent and significant difficulties with the written word. It can affect not only reading, but also reading comprehension and writing difficulties.

What is dyslexia and dysorthographia?

Reading difficulties, also called dyslexia, is specifically when the decoding and identification of words is more difficult for a student than for peers of the same age and grade level. Reading and writing disorders refer to difficulty reading words, understanding texts, spelling difficulties and written text difficulties. Most frequently, a student who has difficulties reading will experience the same difficulties in writing. Difficulties evolve over time and can affect two principal aspects :

Sounds and words

  • Segmenting a word into sounds
  • Associating the sounds with the letters
  • Recognizing high-frequency words

Sentence and paragraph

  • Understanding sentence structure
  • Using proper syntax and grammar
  • Reading comprehension
  • Writing longer texts

How to support these

First of all, it is important to note the complexity of written language. Students with written word challenges experience a host of difficulties when understanding or writing paragraphs. In other words, to understand what you’re reading, you need to decode the letters, associate them with sounds, recognize the word, and do so quickly in order to put information together, interpret the information, deduce and predict the next steps and formulate a hypothesis of the sense of the piece you are reading.

To write a paragraph, you need to organise your ideas, adapt the information to your eventual reader, structure the text, select the information to be included, structure the paragraph and the sentences to support your ideas, choose adequate vocabulary, spell the words correctly, and so much more.
It is common for students to experience difficulties at one or several stages of the reading or writing process. A speech language pathologist can evaluate where the difficulties lie and build an intervention plan to support learning through the difficulties. This work is always done in collaboration with the family and the school team.


Written language difficulties, including dyslexia and dysorthographia, can be seen in isolation and in conjunction with other difficulties such as ADHD. Whatever the origin of the difficulties, the speech-language pathologists at the Centre Mosaïque de Québec are here to help.
