ADHD girls vs boys often present differently, which can lead to misdiagnosis or underdiagnosis, especially in girls. While ADHD affects both genders, the symptom differences can make it harder to identify ADHD in girls. Understanding these differences is key to providing accurate support and appropriate treatment.

ADHD in Boys: Hyperactivity and Impulsivity 

In boys, ADHD is often characterised by the more obvious symptoms of hyperactivity and impulsivity. These include restlessness, fidgeting, talking excessively, and interrupting others. Boys with ADHD tend to be more disruptive in school and at home, which makes their symptoms easier to spot. Their behaviour often leads to early intervention and a clearer diagnosis. 

ADHD in Girls: Inattention and Subtle Symptoms 

On the other hand, ADHD in girls is typically marked by inattention rather than hyperactivity. Girls may struggle with staying focused, organising tasks, following instructions, and remembering important details. They are less likely to act out and may internalise their difficulties, which often leads to them being misunderstood as lazy, disorganised, or daydreamers. These more subtle behavior patterns can easily be overlooked by teachers, parents, and even healthcare providers, leading to delayed diagnoses. 

Why ADHD in Girls is Often Missed 

Girls with ADHD often learn to mask their symptoms, especially as they grow older. They may adapt by becoming more perfectionistic, overcompensating for their struggles, or working harder to keep up with their peers. This masking can result in ADHD being missed or misdiagnosed as anxiety, depression, or just “poor behaviour.” 

Recognising the differences between ADHD girls vs boys is crucial for understanding and diagnosing ADHD accurately in both genders.
