ADHD Comorbidity Prevalence in US Adults

Plain-language summary

Research suggests that ADHD commonly co-occurs with other mental health conditions like anxiety and depression, especially in women. This can make diagnosis tricky because the symptoms often overlap. While many people experience "hyperfocus," its role in diagnosis and treatment is still being explored.

Key findings

• ADHD is frequently observed alongside anxiety and depression, particularly in women seeking psychiatric care.
• The overlap in symptoms between ADHD, anxiety, and depression can complicate accurate diagnosis.
• Hyperfocus is a reported experience among individuals with ADHD, anxiety, or depression, but its specific diagnostic value requires more investigation.

   ObjectiveThis study investigated ADHD comorbidity and clinical features, including hyperfocus, in women with depressive or anxiety disorders, addressing the diagnostic complexities arising from symptom overlap and the underdiagnosis of ADHD in this population.MethodsFemale patients from outpatient psychiatric clinics (n = 170) were assessed using the Beck Depression Inventory and Beck Anxiety Inventory. Participants meeting threshold scores underwent further evaluation with the Wender-Utah Rating Scale, Hyperfocus Scale, and Adult ADHD DSM-IV-Based Diagnostic Screening Scale, complemented by s
