🤕 Migraine Trigger Diary Pattern Recognition Simulator

Starting the Migraine Trigger Diary

Every attack gets logged next to the day's possible triggers.

• 5: Tracked Factors (sleep, stress, food, weather, hormones)
• ~2 min: Entry Time (per day, evening review)
• 4 wks: Minimum Useful Window (before patterns are reliable)
• +40%: Attack Recall Accuracy (diary vs memory alone)

Why log at all

Memory alone misses subtle recurring triggers.

What gets recorded

Sleep hours, stress level, meals, weather, cycle day.

Building the habit

Same time each evening keeps entries consistent.

Sparse Data Hides Real Signal

A week or two of entries is simply too little to trust.

• <14: Entries So Far (days logged)
• High: False Pattern Risk (small samples mislead easily)
• 1–3: Attacks Observed (not enough for statistics)
• Low: Confidence Level (noise dominates the signal)

Random noise looks like signal

Coincidences happen often in tiny datasets.

Patience matters

Jumping to conclusions early wastes the diary.

Keep logging anyway

Every extra day sharpens the eventual picture.

A Trigger Pattern Starts Emerging

Poor-sleep nights begin clustering right before attack days.

• 4–6: Weeks Logged (enough for early trends)
• Sleep: Leading Trigger (strongest early correlate)
• ~0.4: Correlation Strength (moderate, still noisy)
• ~50%: Attacks Explained (by this one trigger)

Sleep debt stands out

Short sleep nights repeatedly precede migraine days.

Other factors fade

Weather and food show weaker, inconsistent links.

Still needs confirmation

One good stretch of data is not proof.

The Pattern Becomes Statistically Solid

More logged weeks push the sleep-trigger correlation higher.

• 8–12: Weeks Logged (strong sample size)
• ~0.7: Correlation Strength (clinically meaningful)
• ~70%: Attacks Explained (by identified trigger)
• High: Confidence Level (pattern holds across weeks)

More data, less noise

Longer logs average out one-off coincidences.

A trigger worth acting on

Sleep deprivation now predicts most attacks.

Time to intervene

Confirmed patterns justify a targeted lifestyle change.

Avoiding the Trigger Reduces Attacks

Protecting sleep on schedule measurably lowers attack frequency.

• 0–100%: Avoidance Compliance (adjustable behavior change)
• up to 70%: Attack Reduction (at full compliance)
• 2–3 wks: Time to Benefit (after consistent avoidance)
• Yes: Diary Still Useful (catches new triggers too)

Behavior follows evidence

A confirmed trigger makes avoidance worth the effort.

Partial compliance still helps

Even imperfect sleep habits lower attack days.

The diary keeps working

Continued logging catches any new emerging trigger.
