Did you know?

More than 7% of the population has DLD (dysphasia). This represents about 2 students per classroom.

Here are the differences between DLD, a language disorder (LD), and a language delay.

DLD or Dysphasia?

Developmental Language Disorder (DLD) is the new term for dysphasia. In September 2017, the Order of Speech-Language Pathologists and Audiologists of Quebec (OOAQ) began using this term.

Other terms used for Developmental Language Disorder include:

  • Dysphasia

  • Primary Language Disorder

  • Audimuteness

  • Congenital Aphasia

These terms all mean the same thing. It is the same diagnosis.

What is DLD?

DLD is a neurodevelopmental disorder present from birth. The severity varies from person to person.

DLD can bring several language difficulties that affect both comprehension and expression.

Examples include:

  • Using and understanding words

  • Understanding instructions and being able to follow them

  • Knowing what to answer to a question

  • Formulating clear sentences

  • Learning new information and generalizing it

  • Telling a story or event in the correct order

  • Understanding and following “social rules”

  • Socializing appropriately

  • Making friends and maintaining social relationships

  • Producing speech sounds

Other diagnoses, associated disorders, may occur alongside DLD

  • Speech disorders : The person has difficulties that affect different aspects of speech, such as:

  • Articulation : How the parts of our mouth are positioned to produce sounds
  • Fluency: How smoothly ideas come out when we speak
  • Voice production : The sound that comes out of our mouth when we talk

  • Developmental Coordination Disorder (DCD) : “The person has difficulty planning and controlling movements. Individuals may appear more clumsy. This disorder may affect both fine and gross motor skills.”

  • Fine motor skills : Difficulty making precise movements, such as cutting a shape with scissors or washing and drying dishes
  • Gross motor skills : Difficulty jumping, walking, running, handling objects like a ball, balancing, etc.
  • Auditory Processing Disorder (APD) :The person has difficulty perceiving and processing different sounds. Their brain does not properly process the sounds that the ears hear.

  • Speech Sound Disorder (SSD)

  • Developmental Dyslexia

  • Specific Learning Disorder(dyslexia, dysorthographia, dyscalculia)

  • Attention Deficit Hyperactivity Disorder (ADHD)

  • Behavioral Disorders: The person may have inappropriate reactions, such as:

  • Opposing
  • Arguing
  • Being aggressive

Other difficulties may accompany DLD

  • Visual perception difficulties: The person has trouble understanding what they see. It becomes even harder when there is a lot of visual information.

  • Spatial orientation difficulties: The person struggles to navigate places - finding their way or knowing where they are.

  • Difficulty with abstraction: The person has difficulty identifying what information is important when there is a lot to process.

  • Difficulty with generalization: The person has trouble applying previously learned information to a new or different situation.

  • Difficulty perceiving time: The person has difficulty understanding time—estimating, organizing, or locating themselves in time.

  • Sensory difficulties: The person may be more sensitive (hypersensitive) or less sensitive (hyposensitive). Sensory difficulties may relate to touch/textures, noise/sounds, smells, or light.

Executive Functions and DLD

We often think that people with Developmental Language Disorder (DLD) only have difficulty speaking or understanding.
That is false!
Executive functions are also affected.

What is an executive function?
Executive functions help us learn, organize, and control:

  • Our behaviors

  • Our thoughts

  • Our emotions

Examples of executive functions

  1. Attention:
    Being able to concentrate and ignore unimportant things.

  2. Memory:
    Being able to remember information or keep it in mind.

  3. Flexibility:
    Being able to find new solutions to problems.

  4. Organization:
    Being able to plan ideas and actions.

  5. Inhibition:
    Being able to stop our actions or words - like a filter that prevents us from saying or doing everything that comes to mind.

Examples of everyday difficulties related to executive functions:Voici des exemples de difficultés de la vie quotidienne qui sont liées aux fonctions exécutives:

1) Managing money

Money management may be difficult for someone with DLD. It requires executive functions such as:

  • Inhibition

  • Memory

  • Organization

2) Hygiene

Maintaining good hygiene can be difficult for someone with DLD. It requires executive functions such as:

  • Organization

  • Flexibility

  • Memory

3) At school or work

A person with DLD may face many difficulties in school or work environments. These settings require a lot of energy and rely heavily on executive functions such as:

  • Organization

  • Flexibility

  • Attention

  • Inhibition

  • Memory

Défis courants chez les personnes atteintes du TDL

Les personnes atteintes de troubles du développement du langage (TDL) sont souvent confrontées aux cinq principaux défis suivants, dont la gravité varie d'une personne à l'autre :

  • Difficultés linguistiques : Elles affectent à la fois la compréhension et l'expression verbales, y compris la syntaxe, la sémantique, la phonologie, la pragmatique et le discours.

  • Problèmes de perception auditive : Difficulté à distinguer et à mémoriser les signaux auditifs, en particulier ceux liés à la durée des sons.

  • Problèmes de pensée abstraite : Difficultés à identifier les éléments essentiels dans des situations complexes, avec une meilleure compréhension des concepts concrets.

  • Difficultés de généralisation : Difficulté à appliquer les concepts appris à des situations nouvelles ou différentes.

  • Problèmes de perception du temps : Difficulté à comprendre les concepts temporels et à effectuer des tâches liées au temps.

Comment l TDL peut être observé à travers les âges

Le trouble développemental du langage (TDL) présente des défis uniques qui varient à travers les groupes d'âge. Voici six exemples illustrant la façon dont le trouble du développement du langage peut se manifester :

Autonomie

Les adultes atteints du TDL peuvent faire preuve de rigidité face au changement. Par exemple, ils peuvent avoir du mal à s'adapter lorsqu'un superviseur modifie la façon dont une tâche familière est exécutée au travail.

Langage

Les enfants d'âge scolaire peuvent avoir du mal à organiser leur discours de manière cohérente. Par exemple, ils peuvent passer d'un sujet à l'autre sans lien entre eux lorsqu'ils décrivent leur week-end, ce qui fait que les auditeurs ont du mal à les suivre.

Motricité globale

Les enfants d'âge préscolaire peuvent rencontrer des difficultés dans les activités physiques nécessitant de l'équilibre, comme marcher en ligne droite ou sauter sur place avec les deux pieds simultanément.

Motricité fine

Les tâches de motricité fine, comme couper des légumes ou verser des liquides, peuvent être plus complexes pour les adultes en raison de la précision requise, ce qui peut affecter leur capacité à cuisiner efficacement.

Écriture et lecture

Les enfants d'âge scolaire peuvent éprouver des difficultés à écrire proprement dans des espaces définis ou à lire des mots complexes dans un texte, faisant souvent des pauses ou des hésitations.

Compétences cognitives

Les enfants d'âge préscolaire peuvent éprouver des difficultés à séquencer des tâches, comme l'organisation correcte d'images montrant une plante en train d'être arrosée, de grandir et de s'épanouir.

Frequently Asked Questions

Do all people with DLD have the same profile?

No, severity varies from person to person. It is difficult to describe a single profile for someone with DLD because everyone is different. However, all people with DLD experience these five difficulties:

  • Language disorders

  • Auditory perception disorder

  • Difficulty with abstraction

  • Difficulty generalizing information

  • Difficulty perceiving time

How many people in Quebec have Developmental Language Disorder?

According to the Order of Speech-Language Pathologists and Audiologists of Quebec (OOAQ), 7% of the population has DLD. That equals 1 person out of 14, or about 2 children per classroom.

Is my child more likely to have DLD if someone in my family has it?

Yes. If someone in your family has DLD, your child is 2 to 7 times more likely to have DLD. DLD can be partially hereditary.
What is a hereditary disorder?
A hereditary disorder means the condition can come from family genetics. DLD can be passed from a parent to a child.

How can I help someone with DLD?

To help someone with DLD better understand, you can:

  • Check understanding by asking, “What did you understand?”

  • Use simple words

  • Emphasize important words

  • Repeat if requested, without getting impatient

  • Speak more slowly

  • Use positive sentences — for example, say “walk slowly” instead of “don’t run,” because negation is harder to process

  • Use visual supports

To help a child with DLD speak better, you can:

  • Describe everyday objects and actions — this helps the child learn more words

  • Speak to the child often

  • Repeat words and sentences, correcting errors gently by emphasizing the right word without saying it’s wrong.
    Example: if the child says, “eat the carrot,” the parent can respond, “Yes, he is eating the carrot.”

  • Say correct sentences without forcing the child to repeat them

Does DLD last a lifetime?

Yes. DLD is a neurodevelopmental disorder, meaning the brain of a person with DLD is built differently. A person with DLD can improve and develop coping strategies. In adulthood, challenges remain, but the person may manage them better by using their strategies effectively.
