As a parent or caregiver, there’s nothing more pleasurable and rewarding than seeing our children grow and thrive. This includes everything, right from interacting with family and friends, to performing well in a school environment, and eventually in their professional lives.

Among all this, one crucial aspect of every child’s development is their ability to communicate effectively. However, for some children, this development can be hindered by speech and language disorders. These can be difficult to understand and diagnose, leaving many parents feeling confused and overwhelmed.

Here, we will explore the different types of speech and language disorders that children can experience, the possible causes behind them, and how they can be diagnosed. We’ll also touch on some of the challenges that children with these disorders may face in their daily lives, as well as the various treatments and therapies that can help them overcome these challenges.

By gaining a better understanding of these complex issues, you can better support and advocate for children who are struggling with these conditions.

What are speech and language disorders?

Most children develop their communication skills naturally as they grow, but some may experience difficulties. Medically, these can be diagnosed as speech and language disorders, which reflect difficulties in understanding and using language effectively.

There are two main categories of speech and language disorders:

  1. Receptive Language Disorder: This type of disorder affects a child’s ability to understand words they hear or read. Children with this disorder may struggle to follow instructions, respond to questions, or understand conversations.
  2. Expressive Language Disorder: This type of disorder affects a child’s ability to use language to express their thoughts and feelings. Children with this disorder may have trouble with word order, grammar, and vocabulary, and may struggle to form complete sentences or express themselves clearly.

It’s worth noting that some children may experience both receptive and expressive language disorders, which can further impact their ability to communicate effectively.

Speech and language disorders are often diagnosed in children between the ages of 3 and 5.

What are the different types of speech and language disorders?

Speech and language disorders can manifest in different ways and can be classified into various types.

Here are some common types of speech and language disorders in children:

  1. Articulation Disorders: These disorders involve difficulties with pronouncing sounds correctly, resulting in unclear speech. Children with articulation disorders may substitute, omit, or distort sounds, which can affect their speech intelligibility.
  2. Language Disorders: These disorders involve difficulties with understanding and using language effectively. Language disorders can affect a child’s ability to express themselves, understand instructions, and follow conversations.
  3. Fluency Disorders: These disorders involve disruptions in the normal flow of speech, such as stuttering. Children with fluency disorders may repeat sounds, syllables, or words, prolong sounds, or have difficulty starting or completing words or sentences.
  4. Voice Disorders: These disorders involve abnormalities in pitch, volume, or quality of the voice. Voice disorders can affect a child’s vocal pitch, loudness, or voice quality, resulting in a hoarse, breathy, or strained voice.

Speech and language disorders among children in Canada

Speech and language disorders in children are common in Canada, with between 8% and 12% of preschoolers experiencing some form of language impairment.1 Hearing and vision difficulties also affect a significant number of children aged 0 to 14, with approximately 13.1% and 9.2% of children with disabilities experiencing hearing and vision problems, respectively.2

Speech-related disability in itself affects roughly 67,000 children in Canada aged 5 to 14, with a higher prevalence in boys than girls.

Overall, speech and language disorders are estimated to affect around 13% of children between the ages of 2 and 5 years, with a higher prevalence in males.2

These disorders can occur in isolation or coexist with other conditions, and may result from primary conditions such as head injury or epilepsy, or from a lack of stimulation or abuse. It is important that children with speech and language disorders are referred to a Speech-Language Pathologist for a full assessment of their abilities.3

Studies have shown repeatedly that early detection, diagnosis and particularly early intervention make a huge difference in the lives of children.

Early intervention and treatment can even make the difference between continuous progress and long-term lifelong challenges.1

Therefore, if you as the parent or caregiver notice your child or children having any kind of speech or language difficulties, it is important to take them to a medical center or qualified medical professional, such as a speech and language pathologist, who can do an immediate and comprehensive diagnosis.

What are the causes of speech and language disorders in children?

There is no one specific cause for speech and language disorders in children. Each case can be different, and manifest in different ways. However, in general, there are some broadly accepted factors that could be instrumental in causing developmental delays or disorders in young children.

These include, but are not limited to:

  1. Developmental Factors: Some speech and language disorders may be related to a child’s developmental stage. For example, speech sound disorders are common in young children as they learn to coordinate their speech muscles and produce sounds accurately.
  2. Genetic Factors: Certain speech and language disorders may have a genetic component, meaning they can run in families. If a close family member, such as a parent or sibling, has a history of speech and language disorders, a child may be at a higher risk of developing a similar condition.
  3. Environmental Factors: Environmental factors, such as exposure to chronic ear infections, hearing loss, or speech-language stimulation, can impact a child’s speech and language development. Additionally, a lack of exposure to multiple languages or limited opportunities for communication and interaction may also affect speech and language skills.

How are speech and language disorders diagnosed in children?

The diagnosis of speech and language disorders typically involves a comprehensive evaluation by a qualified speech-language pathologist.

The evaluation may include the following steps:

  1. Case History: The speech-language pathologist will gather information about the child’s medical history, developmental milestones, and communication skills.
  2. Speech and Language Assessment: The child’s speech and language skills will be assessed using standardized tests, observation, and analysis of speech samples. This may include assessing articulation, language comprehension, expressive language skills, and other relevant areas of communication.
  3. Hearing Assessment: A hearing assessment may be conducted to rule out any hearing-related issues that may be affecting the child’s speech and language skills.

Depending on the suspected speech and language disorder, additional assessments may be conducted, such as assessments of fluency, voice, and oral motor skills.

What happens after the diagnosis?

First, the speech-language pathologist will analyze and interpret the assessment results to determine the presence and severity of speech and language disorders. They will then develop an individualized treatment plan tailored to the child’s needs.

They can recommend appropriate interventions and follow-up, which may include monitoring, periodic consultation with home programming, or intensive speech-language therapy.

In some cases, the speech-language pathologist may collaborate with other professionals, such as pediatricians, audiologists, psychologists, or educators, to ensure a comprehensive approach to diagnosis and treatment.

Fortunately, speech-language services are widely available in Canada, and can be found in most hospitals, rehabilitation centers, schools, as well as in certain CLSCs (local community service centers) and private clinics.

It’s important to know that children can be referred to a Speech-Language Pathologist as early as 1 year of age.

Early intervention is crucial in addressing speech and language disorders in children, as it can improve outcomes and help them develop the communication skills necessary to succeed in school and in life.

Treatment for speech and language disorders

Treating speech and language disorders in children typically involves speech-language therapy, which is delivered by a qualified speech-language pathologist. The therapy sessions may be individual or in a group setting, depending on the child’s needs.

The goals of speech-language therapy may include improving speech articulation, language comprehension, expressive language skills, fluency, voice, and other relevant areas of communication.

What can parents do to support children with speech or language difficulties?

In addition to speech-language therapy administered by medical professionals, parents and caregivers play a critical role in supporting their child’s speech and language development.

If you have a child who has been diagnosed with such a condition, here are some steps you can take to support their development and help them overcome challenges and better assimilate into school and general society:

  1. Create a Language-Rich Environment: Provide ample opportunities for your child to listen, speak, and interact in a language-rich environment. Talk to your child, read books together, sing songs, and engage in conversations to promote language development.
  2. Encourage Communication: Encourage your child to communicate using words, gestures, or any other means of expression. Avoid finishing their sentences or speaking on their behalf, and give them time to express themselves.
  3. Provide Positive Reinforcement: Praise and reinforce your child’s efforts in communicating, even if their speech or language may not be perfect. Positive reinforcement can boost their confidence and motivation to communicate.
  4. Follow Medical Recommendations: Strictly and rigorously follow all of the recommendations and strategies provided by the speech-language pathologist to support your child’s speech and language goals at home.
