Could Allergies Be Causing Learning Difficulties

When we think of childhood allergies, we typically picture watery eyes, sneezing, or hives. However, underlying allergic reactions can sometimes manifest as extreme restlessness and behavioural challenges, occasionally leading to a misdiagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD).

A Classroom Wake-Up Call

Could underlying allergies be behind a child's sudden restlessness or classroom challenges? Before jumping straight to behavioral diagnoses or medications, it is always wise to look closer at potential physical triggers. Read on to learn how a routine allergy test completely transformed—and saved—one of my student's lives in Scarborough.

Years ago, while teaching in Scarborough, Ontario, I had a student who was incredibly energetic. In my hands-on classroom, this was never an issue; students were encouraged to move around and channel their physical energy into their learning. Unfortunately, the educator slated to teach him the following year favoured a much stricter, sedentary approach. Concerned by the child's activity levels, this colleague demanded to know when I planned to advise the parents that their son had ADHD.

My response was clear: "I am an educator, not a medical professional, and it is not my place to make a clinical diagnosis."

However, the interaction sparked a memory. I’d recently watched a talk show highlighting children who had been misdiagnosed with ADHD. It was shocking to see how severe food allergies could trigger extreme behavioural spikes. In one dramatic case, a child exposed to an allergen began exhibiting erratic, animal-like behaviour.

Prompted by this insight, I approached the parents and gently asked if their son had ever been tested for allergies, sharing what I had observed in class alongside the information from the program.

A Life-Saving Discovery

A few days later, the child's mother returned to the classroom with profound news: "You saved our son's life."

Medical testing revealed that the boy was severely anaphylactic to shellfish. Because the family was from eastern Canada, shellfish was a staple of their regular diet. The constant exposure was causing chronic, low-grade physical distress that manifested as severe hyperactivity.

The Takeaway for Parents and Educators

Allergies are complex and should never be underestimated. If an educator or medical professional suggests that your child may have ADD or ADHD, it is always wise to explore all avenues. Before jumping straight to behavioural medication, consider scheduling an appointment with an allergist. A simple allergy test could change—or even save—your child's life.

If your child is struggling with mysterious behavioural or focus shifts, exploring underlying medical triggers is a vital first step. I highly recommend reading The Allergy Solution: Unlock the Surprising, Hidden Truth about Why You Are Sick and How to Get Well by Dr. Leo Galland and Jonathan Galland, which provides a brilliant look into how resetting immune balance can reverse hidden obstacles to learning and health.
