Are women with ADHD actually less common than men, or just diagnosed less?

Diagnosed less, not necessarily less common. ADHD likely affects a broadly similar proportion of women and men, but the diagnostic criteria were developed almost entirely from studies of hyperactive boys, and clinical diagnosis ratios have historically run anywhere from 2:1 to 16:1 male to female, a gap far too large to reflect true prevalence difference alone. Women more often present with inattentive or internalized symptoms that get misread as anxiety, mood issues, or personality traits rather than recognized as ADHD, which is part of why average diagnosis age for women tends to run later. FasTreat also offers private online ADHD assessment and ongoing care, depending on your needs and clinical assessment.
