Keep a simple symptom record to talk through changes around your period.

**The number:** Record premenstrual symptoms for at least 2 menstrual cycles ([NHS, 2024](https://www.nhs.uk/conditions/pre-menstrual-syndrome/))

## The evidence

- How sure: Certainty of evidence: Not rated. Measured in the general population; we say so because ADHD trials of this do not exist or are too small.
- Evidence grade: C. Grade C: small or mixed studies, expert consensus or clinical practice. Worth knowing, not worth betting on.
- Basis: Small, heterogeneous ADHD hormone studies and general NHS symptom-diary guidance; no formal GRADE rating or tracking-treatment trial.
- Outcome: duration of premenstrual symptom recording
- Comparison: general PMS assessment guidance
- Benefit: 36/100. The benefit score is an editorial prioritization for the general list, weighted by certainty. It is not a prediction of what will happen for you.

## Why it matters

A 2025 review of 11 studies, 4 on the menstrual cycle, suggests ADHD symptoms may vary across the cycle, but the studies were few, small and varied. General NHS advice recommends recording premenstrual symptoms across at least two cycles to inform an appointment. Tracking can help a conversation, but no reliable ADHD benefit or standard medication adjustment can be promised from the current hormone evidence.

## How to do it

1. If you notice a pattern, jot down period timing, sleep, concentration and any physical or mood symptoms.
2. Take the record to a clinician when the symptoms affect your daily life.
3. Ask what else could explain the changes, and whether you need further assessment.

## Talk to a clinician first

Do not use cycle timing to change medicines yourself. Seek help for severe symptoms without waiting to finish a diary.

## Putting it into practice

### Start now

- 1 minute: Ask yourself whether the changes you want to raise seem to line up with your period.
- 5 minutes: Make a brief note of today's symptoms and where you are in your cycle, if known.
- 15 minutes: Prepare questions for a clinician using any cycle and symptom information you already have.

### What it looks like

- Note that concentration and sleep seem worse before your period, with the dates.
- Bring cramps, bleeding or mood changes into the same clinical discussion.

### Common mistakes

- One hard week can't show a hormonal cause. Look for a pattern that repeats.
- A symptom diary doesn't set a medication plan. Treatment decisions stay with the prescriber.

### A structured start

**Record enough to discuss**

1. Choose a few symptoms that affect daily life.
2. Make brief entries across cycles when feasible.
3. Bring the pattern, including exceptions, to the appointment.
