Are There Gender Differences in ADHD Prevalence According to DSM-5? 

The DSM-5 acknowledges that there are significant ADHD gender differences in the prevalence and presentation of ADHD. Research shows that ADHD is more commonly diagnosed in boys than in girls, with a higher boys vs girls ADHD ratio. However, this difference may partly be due to diagnostic bias and differences in how ADHD symptoms manifest across genders. 

In boys, ADHD symptoms are often more outwardly noticeable, such as hyperactivity and impulsivity, which can lead to an earlier diagnosis. Girls, on the other hand, may display more subtle symptoms, such as inattention and daydreaming, which can be easily overlooked. As a result, ADHD in girls is often underdiagnosed or diagnosed later in life. 

The DSM-5 highlights these gender prevalence differences and calls for clinicians to be aware of how ADHD symptoms may present differently in boys and girls. This helps to reduce diagnostic bias, ensuring that both genders are appropriately assessed for ADHD, even if their symptoms don’t fit the typical patterns observed in boys. 

How It Helps 

Understanding ADHD gender differences helps clinicians make more accurate diagnoses. By recognising how ADHD manifests differently in boys and girls, healthcare providers can avoid diagnostic bias and ensure timely intervention. This leads to better support and treatment tailored to the specific needs of each individual, regardless of gender.
