Attention-deficit/hyperactivity disorder (ADHD), though now classified in the Diagnostic and Statistical Manual (DSM-5) as a neurodevelopmental disorder, has been framed in myriad ways over the last century. Regardless of framing, however, the diagnostic category has consistently occupied a contentious space in public discourse and medical systems alike. Even though current research in clinical psychology estimates that ADHD is likely underdiagnosed and undertreated, particularly among women, debates which question the legitimacy and prevalence of the disorder continue to persist. The last two years have witnessed a pushback to underdiagnosis with assistance from an unlikely source: social media. Platforms like Instagram and TikTok have seen increasing amounts of content produced on the disorder, with particularly profound consequences for women. Significantly, women have taken to these platforms to share experiences with the disorder, spreading awareness of the differences in symptom presentations for women and illuminating the paradox of being diagnosed with a neurodevelopmental disorder in adulthood. Using qualitative data collected from Zoom interviews, social media posts, and comment sections, I seek to elucidate the dual phenomenon of late diagnoses of ADHD in women and the proliferation of ADHD content online. I ask: what becomes of those who are not the center of the DSM’s gaze? And how does one form reality in the biomedical periphery? In answering these questions, I evaluate how women reorient themselves after the rupture caused by a “late” diagnosis and interrogate the role of social media to understand how women find their bearings in the wake of a late diagnosis.
