Hi, I’m Helene. In May 2026, I’ll be running the Leiden Marathon for PMDD (Premenstrual Dysphoric Disorder).
PMDD is a severe, hormone-based mood disorder that can cause anxiety, rage, depression, and in some cases, suicidal thoughts in the luteal phase of the menstrual cycle.
Why this matters:
- Over 30 million women and AFAB people are affected worldwide.
- A 2024 global study found that 82% of people with PMDD experience suicidal thoughts every month, and 1 in 4 have attempted suicide.
- Despite the urgency, a diagnosis takes on average 12 years.
There’s barely any research. Most people, including many doctors, don’t know it exists.
So I’m running 42.2 km (+ 100s more during training) to raise funds for two incredible organisations fighting for change:
The PMDD Project (UK) – supporting awareness, research, and advocacy.
Stichting PMDD Nederland – building community, visibility, and care locally.
Thank you for your support.
Together we’ll push for the recognition and support PMDD deserves.
Because PMDD awareness is suicide prevention.
With love and determination,
Helene
