Has brain fog become a regular companion in your luteal phase or during perimenopause? Dr.Em, a neuroscientist from Oxford and Harvard explains how and why it happens in both cases 🤔

Right before your period, your brain’s pain circuits are still deciding how much a cramp is going to hurt.

Researchers writing in PAIN Reports (2025) applied brain stimulation over the motor cortex in women with severe menstrual pain, starting a few days before their period. The stimulation produced a measurable change in connectivity between the periaqueductal gray, the brain’s own pain control center, and the motor cortex. That change predicted less pain in the following cycle.

That’s neuroplasticity doing exactly what it’s built for: the brain relearning how to regulate pain.

The study was small, 28 women, and the researchers call it preliminary. But it’s real evidence that menstrual pain can be treated at the level where pain actually gets processed: the brain.

You reread the same sentence three times and still don’t know what it says.

That’s not you losing your edge. That’s your brain, days before your period, running on less dopamine and more of a compound that quite literally slows it down.

Swipe to see exactly what’s happening in there, and why some cycles hit so much harder than others.

Day 1 can feel like the hardest day of your cycle because estrogen and progesterone are both at their lowest, and your brain is adjusting to that shift in real time.

That’s neuroplasticity: the brain learning, cycle after cycle, how to respond to hormonal change.

On harder days, 20 minutes using the Samphire Headband can make a difference. You’re not fixing your hormones. You’re giving your brain support while it relearns to respond to them.

Cycle syncing for food and exercise gets the most attention. But the research on the brain across the menstrual cycle points somewhere more specific.

Cortical excitability, neuroplasticity, and the brain’s response to stimulation all shift by phase. Timing your brain support to your cycle isn’t a wellness trend. It’s what the neuroscience points toward.

This is what the research shows.

Cortisol affects every woman’s brain differently across the month – and in PMDD, the stress axis itself appears dysregulated in ways research is only starting to map.

The gold standard of clinical research wasn’t designed around the complexity of women’s lives.

Double-blind RCTs are the most rigorous evidence we have – but they require excluding women with more than one condition. The women who need answers most are often the ones the trial can’t include.

That’s why here at Samphire we run three types of studies. RCTs for regulatory-grade evidence. Open-label trials to explore new territory safely. Observational studies to learn from real women, with all their complexity, in real life.

Your PMS or PMDD was never a hormone problem.

The first genome-wide study of premenstrual experiences – 72,000 women – found no genetic link to estrogen levels. The strongest signal was a brain gene.

Swipe to see what that means for how we can treat it with non-invasive neurostimulation. Also, you can check more of our users’ reviews on Trustpilot!
