Are Preschoolers Overdiagnosed With ADHD? 

Concerns about preschool ADHD overdiagnosis have grown in recent years, as more young children are being assessed for behavioural and attention issues. While early identification can be helpful, diagnosing ADHD in toddlers and preschoolers is tricky because many typical behaviours at this age naturally resemble ADHD symptoms. 

At ages 3 to 5, it’s normal for children to be impulsive, energetic, or have short attention spans. However, in structured settings like nurseries or early classrooms, these behaviours can raise red flags. The danger comes when developmentally typical actions are too quickly labelled as early childhood ADHD, leading to potential ADHD misdiagnosis and unnecessary treatment. 

Why ADHD May Be Overdiagnosed in Preschoolers 

Here are a few reasons why preschool ADHD overdiagnosis occurs: 

Developmental variability  

Children develop at different rates one child’s restlessness may be age-appropriate, while another’s may be a concern. 

Pressure from structured environments  

Preschools with rigid routines may see normal behaviour as disruptive, prompting early referrals. 

Limited diagnostic clarity  

There’s a lack of age-specific tools to accurately assess ADHD in toddlers, increasing the risk of misjudgment. 

In conclusion, while it’s important to support children with genuine needs, it’s equally crucial to avoid pathologising normal early childhood behaviour. Careful, age-appropriate evaluation is key to avoiding overdiagnosis in the preschool years.
