“My ADHD medication works… except the week before my period.”
If you’ve heard something like this from a client, they’re not imagining it.
For many people with ADHD, symptoms don’t remain consistent throughout the month. Instead, attention, emotional regulation, working memory, and executive functioning may fluctuate alongside hormonal changes across the menstrual cycle.
A recent scoping review examined the growing body of research on menstrual health and ADHD. While the evidence is still emerging, the findings suggest a meaningful relationship between hormonal fluctuations and ADHD symptom severity (Kennedy et al., 2026).
The review identified six recurring themes across 20 studies. These included worsening ADHD symptoms during certain phases of the menstrual cycle, higher rates of menstrual difficulties among people with ADHD, attentional challenges related to menstrual pain, menstrual side effects associated with stimulant medication, and early evidence supporting interventions tailored to the menstrual cycle.
For mental health professionals, this is an important reminder that context matters.
When a client describes feeling more forgetful, emotionally reactive, overwhelmed, or unable to focus at predictable points in their cycle, it may not be a lack of motivation or a setback in treatment. It may reflect the interaction between fluctuating hormones and ADHD.
Encouraging clients to track both their menstrual cycle and their ADHD symptoms can help identify patterns that might otherwise be missed. This information can also support conversations with physicians or psychiatrists about individualized treatment strategies.
The review also highlights an important gap in healthcare. Despite increasing recognition of these cyclical changes, research remains limited, and many people report feeling dismissed when they raise concerns about the impact of their menstrual cycle on ADHD symptoms. More high quality research is needed, but the existing evidence suggests these experiences deserve to be taken seriously.
When we recognize that mental health does not exist separately from hormonal health, we create space for more compassionate, individualized care.
Sometimes one of the most validating things we can say is, “There may be a pattern here, and it’s worth paying attention to.”
