By the time Mattis reached Grade 3, Cécile and Arsenio grew concerned that he wasn’t meeting certain milestones.

“Mattis struggled to interact with others,” explains Cécile. “Then we realized he was barely writing at school. We knew he could do it, but he just refused. On top of that, his walking wasn’t well coordinated and he wasn’t growing as quickly as his peers physically.”

Cécile and Arsenio became worried that these symptoms were caused by something more serious, so they booked assessments for Mattis at Ron Joyce Children’s Health Centre.

Seeking answers

Mattis always had challenges with social interactions. An occupational therapist worked with him to develop social skills and confidence, and they also addressed family discipline to help reduce conflict in his life.

“Anxiety and emotional regulation were major challenges for Mattis,” says Cécile. “As a parent, it was difficult to watch him struggle emotionally. The occupational therapist involved him with different groups of peers, including a cooking class, which were very helpful in enabling him to socialize appropriately with other children his age.”

Recently, Mattis was diagnosed with level 1 autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD), which explains his difficulties with peers and family.

At the same time, Mattis was seen by Endocrinology at McMaster Children’s Hospital, where the team treated Mattis with hormone therapy to support his physical growth into adolescence and beyond.

Originally, Mattis actively resisted taking needles for his hormone treatment, but he soon learned to administer his own shots and follow the directions of health care providers to overcome his fear.

Always developing

“The teams at Hamilton Health Sciences make a major difference in Mattis’s life,” says Cécile. “We still use the services of the Children's Developmental Rehabilitation Program and the Autism Program, which help him develop valuable skills to control his emotions and socialize more comfortably.”

Now 14 years old, Mattis is doing well in school and making new friends. He loves to speak with peers and adults about his passion for science and engineering.

“We are grateful for the care we’ve received as a family. Thanks to the help of many different specialists from Hamilton Health Sciences, Mattis continues to grow and develop with each passing day. It’s been wonderful to watch our son shine and live life to its fullest.”
