Autism is often referred to as autism spectrum disorder (ASD), as the level of severity and symptoms vary from person to person; some people have mild symptoms while others may display severe symptoms.

Autism’s social deficits and behavioural patterns might not be recognised until much later in life when the individual is unable to meet social, educational, occupational, or other important life stage demands.

Diagnosis can significantly improve the quality of life for people living with autism, however, it is not always easy to diagnose. It is not uncommon for people with autism to reach adulthood without a diagnosis.
Diagnosis is usually conducted through an autism assessment. This involves a team of medical experts observing an individual’s behavior and listening to their concerns.
In children, autism is primarily diagnosed through observation. The child may be assessed by a specialist team of health professionals (including a pediatrician, psychologist, speech pathologist and/or a neurologist).
In adult cases, if an individual decides to seek a diagnosis, a team of health professionals will carry out a comprehensive autism assessment. A psychologist or psychiatrist may inquire about an individual's childhood and experiences at school to gain a better understanding of their life. A speech pathologist may also examine social communication skills.

Presently, there are no drug treatments to alleviate the symptoms of autism, nor is there a cure for the condition. However, autism can be effectively managed.
It is important to note that treatment for autism differs from person to person – based on the severity of symptoms.
The aim of these therapies is to improve speech and behavior, and can include:

  • Applied Behavior Analysis (ABA)
  • Occupational therapy - to help with everyday tasks
  • Pivotal Response treatment (a behavioral treatment approach)
  • Relationship Development Intervention 
  • Speech therapy to improve communication skills
  • Play therapy - commonly offered to children with autism, the aim is to help improve social and emotional skills.
