ADHD symptoms girls vs boys often differ significantly, particularly in terms of hyperactivity and inattention. Boys with ADHD are more likely to display outwardly disruptive behaviours such as fidgeting, impulsivity, and constant movement, which are easily recognised as hyperactivity. In contrast, ADHD symptoms in girls are often less overt. Girls with ADHD typically exhibit more subtle signs of inattention, such as daydreaming, forgetfulness, or a lack of focus, rather than the disruptive hyperactive behaviour commonly seen in boys.

The gender presentation of ADHD can lead to differences in diagnosis. Since girls are less likely to display the typical hyperactive symptoms, their ADHD may go unnoticed or be misinterpreted as anxiety, depression, or simply being “shy” or “introverted.” This difference in symptom presentation often results in a delayed or missed diagnosis for many girls.

Common Symptoms

Hyperactivity in Boys

Boys with ADHD tend to display more visible hyperactivity, including constant movement, fidgeting, and difficulty staying seated. These behaviours are more noticeable in structured environments like classrooms, leading to earlier diagnosis.

Inattention in Girls

In contrast, ADHD symptoms in girls are often characterised by inattention, which can manifest as forgetfulness, difficulty staying organised, and trouble completing tasks. These subtle signs may not draw as much attention, delaying diagnosis.

Understanding the behavioural differences in how ADHD presents in girls vs boys is crucial for accurate diagnosis and timely intervention. Recognising these gender-specific symptoms can help ensure that girls receive the support they need for managing ADHD.
