- Layla, a teaching assistant with ADHD, relies on phone alarms to manage her daily routine, but finds her symptoms intensify and control diminishes as her period approaches.
- King's College and Queen Mary University in London are conducting the first study of its kind, tracking 50 women with diagnosed ADHD to map how menstrual cycles affect symptom severity and medication effectiveness.
- Dr Sally Cubbin, a neurodiversity specialist, explains that low oestrogen levels before menstruation reduce dopamine activity, worsening core ADHD symptoms like focus, impulse control, and emotional regulation.
- Héloïse, a 19-year-old student with ADHD, reports that her Ritalin medication becomes ineffective during her period, likening it to losing a vital support tool.
- Dr Jessica Agnew-Blais, lead researcher on the study, says the project could help women integrate ADHD management into their hormonal cycles, not change who they are, calling it a 'starting point' for understanding menopause and perimenopause impacts.
- Women in the study documented increased impulsivity during hormonal lows, including binge eating, overspending, and risky behaviors like skipping contraception, according to clinical observations.
Why it matters: Hundreds of thousands of women in the UK are waiting for ADHD diagnoses, and NHS services are overwhelmed. If the study confirms hormonal cycles reduce medication efficacy, it could shift treatment plans for a significant portion of ADHD patients, affecting how clinicians time prescriptions and support monthly symptom fluctuations.
