585. Unmasking ADHD in Girls and Women w/ Dr. Kathleen Nadeau

Would you rather read the transcript? Click here. In this episode, I sit down with renowned author, psychologist, and CHADD Hall of Fame inductee **Dr. Kathleen Nadeau** to dismantle long-held myths about ADHD. Dr. Nadeau shares her journey as an “accidental ADHD specialist” who helped pioneer the recognition of adult, female, and high-IQ manifestations of ADHD. The conversation explores why girls fly under the diagnostic radar, the exhausting cost of masking, how hormonal shifts dynamically alter symptoms, and how practitioners can overhaul their assessment frameworks to look beyond basic DSM checklists. **Key Moments** - **\[01:07] The “Accidental” ADHD Pioneer:** How a field once thought to only apply to hyperactive, misbehaving boys exploded in the mid-90s to include adults, girls, and women. - **\[10:53] Redefining “Functional Impact”:** Why high-IQ individuals, doctors, and lawyers get missed. *“ADHD is manifested when the demands of our circumstances are greater than can be met.”* - **\[12:56] The Staircase Analogy:** A powerful reframing tool for practitioners. Just because a student or professional achieves an “A” or finishes a project doesn’t mean they didn’t have to “crawl up the stairs” to get there. - **\[22:34] The Estrogen Factor & The Ghost of Research Past:** Addressing the historical lack of female-centric data and how estrogen directly dictates dopamine and serotonin receptor sensitivity. - **\[27:14] Socially Rejected vs. Socially Neglected:** Breaking down the social struggles of girls with ADHD. Hyperactive girls are often rejected as “bossy,” while inattentive girls are silently neglected/isolated. - **\[34:48] The Kindergarten Masking Toll:** The intense cognitive load girls carry to keep from rocking the boat, often leading to school avoidance or after-school behavioral meltdowns (“Screaming Mimis”). - **\[52:20] Internalizing Disorders Require Internalized Inquiries:** Why standard parent/teacher rating scales fail girls and why we must ask them about their qualitative, internal experiences. - **\[01:03:40] Accommodations & ADHD-Friendly Families:** Moving away from rigid symptom-tamping toward environment matching, collaborative problem solving, and making classrooms universally ADHD-friendly. **Cool Things Mentioned** - Craft: the premier membership community for testing psychologists - Crafted Practice: the only in-person business retreat for testing psychologists - Reverb: the premier AI-powered report-writing platform for testing psychologists **Featured Resources** TherapyNotes is the leading EHR system for mental health practitioners.
