Recent discussions in the field of ADHD research have highlighted a critical, yet often overlooked, aspect of the condition: the interplay between female hormone cycles and ADHD symptom severity. In a noteworthy article published by Kelo Harper and Tanya Lewis in Scientific American on January 8th, new insights were shared regarding a conference presentation by Dr. Michelle Martell and her colleagues, shedding light on this important topic.

The Study: Tracking Hormones and ADHD Symptoms

Dr. Martell’s team conducted a longitudinal study involving 97 female college students diagnosed with ADHD. Over the course of their menstrual cycles, participants’ hormone levels were measured daily, and their ADHD symptoms—including inattention and impulsivity—were closely monitored.

The findings revealed a clear pattern:
Participants reported significantly worse ADHD symptoms just before and at the start of their menstrual periods, with a less pronounced effect observed around ovulation.
These self-reported changes were mirrored by measurable differences in cognitive performance on tasks related to ADHD and executive functioning.

Clinical Relevance and Expert Commentary

The Scientific American article also featured insights from Dr. Dora Winan, a researcher and psychiatrist from the Netherlands, who has studied this phenomenon in women with ADHD. Dr. Winan noted that these results align with the experiences reported by many of her patients.
Patients often describe a marked deterioration in their symptoms in the week before their period, with some saying, “Something happens to me in the week before my period where all hell breaks loose,” or, “A couple of days into my period, I look back and don’t recognize myself.”

Dr. Martell, the lead researcher, suggests that these fluctuations are likely driven by changes in estradiol—the most potent form of estrogen. Estrogen is not only a key female sex hormone but also plays a crucial role in brain function, influencing attention, memory, and mood stabilization. Additionally, estrogen helps regulate dopamine, a neurotransmitter closely linked to ADHD.

Broader Implications: Hormones Across the Lifespan

This is not the first time researchers have explored the relationship between female hormones and ADHD. A comprehensive review published in the journal Hormones and Behavior (December 2023) examined the impact of hormonal fluctuations not just across the menstrual cycle, but throughout a woman’s life—including during perimenopause and menopause.

The review highlighted that, while research in this area is still limited, there is growing evidence that hormonal changes can significantly affect ADHD symptom severity. The recent study by Dr. Martell adds to this body of knowledge, reinforcing the idea that fluctuations in female hormones can have a notable impact on ADHD across the menstrual cycle.

Why This Matters

For women and girls with ADHD, understanding the role of hormones is crucial. Recognizing that symptoms may worsen at certain points in the menstrual cycle can help individuals and their healthcare providers develop more tailored and effective management strategies.

Looking Ahead

As research in this area continues to expand, it is hoped that more studies will provide deeper insights into the mechanisms at play and identify targeted interventions to support women with ADHD throughout their hormonal cycles.

For those interested in learning more, the Scientific American article and the review in Hormones and Behavior are excellent resources to explore this important topic further.
