    Definition of diagnoses

    Intellectual Disability

    An intellectual disability (ID) is a diagnosis given to people who have some type of intellectual impairment. This diagnosis is given to people who, before the age of 18, show major limitations in their mental abilities and life skills. These limitations appear in the areas of conceptual, social and practical skills that coexist with the person’s strengths. To identify these limitations, health care professionals evaluate how the person functions in different environments with people of the same age while taking into account the person’s cultural and language background.

    Global Developmental Delay

    Children with a global developmental delay (GDD) develop more slowly than other children the same age. The diagnosis of a global developmental delay is generally given to children under the age of 6 who, compared to other children the same age, are experiencing major delays in several areas of development: fine and gross motor skills; cognition; sensory, social and emotional development; language and communication development; and activities of daily living (eating, hygiene, getting dressed, etc.).

    A diagnosis of an intellectual disability, autism spectrum disorder or global developmental delay can pose different and major challenges for children and their families. It is essential that you get a diagnosis so that your child gets the most appropriate services for their needs.

    Autism Spectrum Disorder

    People with autism spectrum disorder (ASD) have problems with communication and social interaction to varying degrees. These problems appear in the areas of:

    • Mutual social and emotional interaction
    • Non-verbal communication during social interactions
    • Developing, maintaining and understanding social relationships

    People with ASD can also have narrow or repetitive behaviour, activities or interests that may include:

    • Repetition or excessive repetition of actions or phrases.
    • An overly excessive focus on familiarity, inflexible routines, or ritualized verbal or non-verbal patterns.
    • Highly restricted and abnormal interests that can vary in type and intensity.
    • Over-or under-sensitivity to different types of sensory information.

    These characteristics can show up early in the child’s development or they may only fully appear when the social demands of the environment exceed the child’s limited abilities. The severity of ASD has a wide spectrum depending on how much support the child gets to function as well as possible.
