The way ADHD in girls vs boys presents can be strikingly different, often leading to underdiagnosis in girls. Boys with ADHD are more likely to show external behaviours like hyperactivity or impulsiveness, which are more noticeable in school settings. Girls, on the other hand, tend to display symptoms that are internalised, such as daydreaming or disorganisation, which can be mistaken for personality traits rather than signs of a condition.
These gender differences in how ADHD presents mean many girls go undiagnosed or are mislabelled as anxious, shy, or “not trying hard enough.” Understanding the variation in symptom presentation between boys and girls is essential for early recognition and support.

Key Patterns and Inattentive ADHD Traits
Here’s how the core symptoms of ADHD can vary by gender, with a closer look at inattentive ADHD, which is more common in girls:
External vs internal behaviours
Boys are often flagged for interrupting, moving constantly, or acting out. Girls may be more withdrawn, quiet, or prone to zoning out. These patterns influence how quickly teachers or caregivers notice symptoms.
Inattentive ADHD and academic impact
Girls with inattentive ADHD may seem dreamy, forgetful, or inconsistent with schoolwork. These symptoms are easier to miss but can still cause academic and emotional challenges.
Emotional regulation differences
Girls often experience more internal emotional distress, such as low self-esteem or anxiety, tied to undiagnosed ADHD. Early recognition helps prevent these secondary struggles.
