How Do Diagnosis Rates Differ for ADHD-I in Men vs. Women? 

The ADHD inattentive subtype gender rates reveal significant differences between men and women, with women often being underdiagnosed or misdiagnosed. ADHD-I (inattentive subtype) presents differently in women, and as a result, ADHD-I prevalence is often more difficult to detect, especially in women. 

Key Differences in Diagnosis Rates 

Several factors contribute to the differing diagnosis rates of ADHD-I between men and women: 

Presentation differences 

The symptoms of ADHD-I are typically characterised by forgetfulness, disorganisation, difficulty sustaining attention, and a lack of focus. These symptoms tend to be less disruptive compared to the hyperactive and impulsive symptoms more commonly seen in men with ADHD. As a result, women with ADHD inattentive subtype are more likely to go unnoticed, as their symptoms are often internalised or attributed to other factors, such as stress or anxiety. 

Subtlety of symptoms 

The inattentive subtype is often harder to detect in women because it manifests in less overt ways. Many women may exhibit symptoms like daydreaming, poor time management, or forgetfulness, which may be dismissed as personality traits or external factors rather than ADHD. This leads to a delay in diagnosis and a higher likelihood of missed diagnoses. 

Sex-based biases 

 Traditionally, ADHD diagnosis has focused more on hyperactivity and impulsivity, which are more common in men. Subtype differences in ADHD-I often cause women’s symptoms to be overlooked or misattributed to other conditions, leading to lower diagnosis rates for women. 

Impact of the Diagnosis Discrepancy 

The gender gap in diagnosis rates for ADHD-I can have lasting effects. Women who are not diagnosed may face years of frustration, low self-esteem, and difficulties in academic and professional settings. Additionally, untreated ADHD can lead to comorbid conditions like anxiety or depression.
