What to Know About Autism

I want to thank Bethany, my guest poster, for sharing her knowledge on autism with us.  Did you know that autism affects 1 in 66 children in Canada?  I learned this recently and was so surprised at how common it is.  If you think this doesn't affect you in any way, you may be surprised as autism is a spectrum and someone you know and love could very well be on it. Finally, if time is limited, there is a chart included that is a very useful tool. Thank you to Bethany for the oodles of time she put into this post.

Autism prevalence for children and youth in Canada

I have worked with individuals (specifically children ages 2-8) with autism for the past seven years. I started out as a Behaviour Interventionist, working one-to-one with preschoolers with autism. I became increasingly aware of the strengths and challenges that individuals with autism and their families face on a daily basis, and believe that early intervention and continued support services are critical to the development of these kids.

My goal for this post is to inform and provide current research on the definition, causes of and red flags for autism. 

The information below includes links to various reputable sites where further definitions, research and information can be found.

What is Autism?

According to Autism Speaks“Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors.”

This diagram provides an easy visual of the core symptoms of autism, as well as associated neurological issues, systemic issues and related disorders. Expanded definitions of the social challenges, communication difficulties, and repetitive behaviours can be found here

What Causes Autism?

While there is not one specific answer, we do know that there are a variety of factors that can contribute to the disorder. These include:

1. Genetic disposition including gene changes or mutations

2. Environmental factors such as:
- advanced parental age at time of conception (both mom and dad)
- maternal illness during pregnancy
- extreme prematurity
- low birth weight
- difficulties during birth including loss of oxygen to the baby’s brain
- mother’s exposure to high levels of pesticides and air pollution

However, it is important to note that the environmental factors alone do not cause autism, but in combination with genetic risk factors, the risk of having a child with autism increases.   While knowing some of the causes of autism, it is also critical to point out what does not cause autism.

Autism is not caused by bad parenting or cold, unloving mothers or vaccines.

More research is needed to determine the causes and risks of autism. To view current research in the field, you can check out Autism Speaks.

What Are The Red Flags For Autism?
Red flags may look different depending on the child and his/her age, and may be less obvious and subtler in individuals who are on the "higher" end of the spectrum. This is a list of developmental milestones that are present in typically developing children by each year up to age 5. Below is a chart that outlines the core symptoms of autism and what they might look like for children (1) under three and (2) over the age of four. The list has been compiled based on information from Autism Navigator, Autism Speaks, Health Link BC and the Diagnostic and Statistical Manual of Mental Disorders  (DSM-5).

One of the best resources for red flags for autism is available through Autism Navigator.  They have a video glossary that compares the skills displayed by a typically developing child and a child at risk for, or with a diagnosis of autism, for each of the core symptoms. The site requires an email address and password to access the videos, but I would highly recommend registering so you can see firsthand the difference between the two children in each case. There is also a description below each video explaining what you are seeing and which skills are either present or absent in each child.

What you can do if you have concerns:

If you have concerns that a child/individual you know might be at risk for autism, there are some online screening tools you can take. The M-CHAT-R is available to take online through the M-CHAT.org website, as well as through Autism Speaks. This is a checklist that is designed to screen children between the ages of 16-30 months for signs of autism. The M-CHAT-R is also available as a app to download on your phone. Additionally, Autism Canada provides links to 4 types of screening tools for individuals of varying ages which include children under 3, children 3-11 years, teenagers between 12-15 and adults (age 16+). Those tests can be found here.
If the scores indicate that your child may be at risk, contact your doctor. You may also want to refer your child to an Early Intervention/Therapy program. These programs are available locally and provide services for speech-language pathology, occupational Therapy and physiotherapy. They are free services available for children from birth until they enter kindergarten. You can search for service providers  and early intervention programs through Therapy BC.
