Sunday evening. You are drying a pan at your sister’s sink, and you yawn.
Then again.
“That’s six,” your sister says from the table. “You do this the day before.”
You laugh. You have never counted. She has.
By Monday afternoon you are in the dark room, going back over the weekend for the thing that did it.
Months later a headache specialist says it in one line. The yawning was not a tired day. It was the first phase of the attack, and it has a name.
What is migraine prodrome?
The prodrome is the first phase of a migraine attack. It comes before the aura, if you get one, and before the headache.
The American Migraine Foundation says the prodrome can begin several hours or days before the aura or the headache.
Headache doctors also have a formal definition. A 2024 review in Frontiers in Neurology quotes the International Classification of Headache Disorders, the rulebook they work from. It defines the prodrome as symptoms that come 2 to 48 hours before the attack.
The word sounds like a diagnosis. It is only a name for the part of the attack that comes first.
The prodrome phase of migraine, in order
A migraine attack has four phases. The American Migraine Foundation lists them in its timeline of a migraine attack:
- **Prodrome:** the first phase. Mood, energy, appetite and body signs, from several hours to several days before.
- **Aura:** flashing lights, shimmering patterns or blind spots, if you get one.
- **Headache:** the pain, plus nausea and sensitivity to light, sound and smell.
- **Postdrome:** the migraine hangover that follows.
Your diary starts at phase three. The prodrome phase of migraine is phase one. For the full set of lengths, see how early a migraine can start.
The migraine prodrome symptoms list
The American Migraine Foundation lists these migraine prodrome symptoms:
- Irritability
- Depressed mood or changes in mood
- Yawning
- Fatigue
- Difficulty sleeping
- Increased need to urinate
- Food cravings
- Nausea
- Sensitivity to light or sound
- Trouble concentrating
- Difficulty speaking or reading
- Neck pain or muscle stiffness
- Hyperactivity
Look at how little of that list looks like a headache. That is the point.
If the stiff neck is the one you know best, read neck tightness before migraine. It has its own numbers.
Migraine symptoms before the pain: the odd ones
Three items on that list sit oddly in a migraine story. Yawning. Food cravings. Frequent trips to the bathroom.
The American Migraine Foundation calls those three especially unique to the prodrome. They are the ones people file under “just me.”
Food cravings before migraine are easy to blame on the food. A craving for the cheese. A sudden need for sugar. Dr. Rashmi Halker Singh, a neurologist at Mayo Clinic Arizona, writes that some well-known triggers may be signs that an attack has already started. Craving first, cheese second. The cheese takes the blame.
Mood changes before migraine are filed under stress. Irritability. A flat, low day. The list says depressed mood or changes in mood belong to the same phase.
And frequent urination before migraine gets filed under water. Nobody tells their doctor about it. It is on the list too.
Why these? Researchers do not fully agree. A 2025 trial analysis in Nature Medicine noted that brain imaging shows activity in the hypothalamus during this phase. The hypothalamus helps run sleep, appetite and hormones. Same list.
How long does the prodrome last?
It depends on who you ask.
- The American Migraine Foundation: several hours, and sometimes several days.
- The International Classification of Headache Disorders, as quoted in the 2024 Frontiers review: 2 to 48 hours.
- Cleveland Clinic: up to 24 hours before the headache.
Three sources, three ranges. They overlap in the hours before the pain. Your own prodrome is yours to measure, and the first-sign log in the neck tightness article shows you how.
Prodrome vs aura
They are not the same phase, and they are easy to mix up.
The aura, as the American Migraine Foundation describes it, is a visual event: geometric patterns, flashing or shimmering lights and blind spots, usually in both eyes. It builds over at least 5 minutes and can last up to 60 minutes.
The prodrome is slower and broader. Hours, sometimes days. Mood, appetite, yawning, the neck.
Put plainly: the prodrome comes first. The aura, if there is one, comes later. The headache comes after both.
How many people have a prodrome?
Many. The numbers differ.
The American Migraine Foundation says about 70 to 80% of people with migraine have a prodrome at the start of their attacks. The 2024 Frontiers review reports that some research found it in about one third of patients, and describes a diary study where 82% of participants noticed prodromal symptoms and correctly predicted 72% of their attacks.
Studies measure it in different ways, and what people notice can depend on whether they are looking.
What to do with the prodrome
You cannot act on what you cannot see. So start by seeing it.
Keep a first-sign log for a few attacks: the time you first notice anything, what it was, how you slept, what you ate, and the time the headache started. The steps are in the neck tightness article. This is our suggestion, not medical advice.
Then ask your doctor about the early phase. The American Migraine Foundation says that treatment in this phase may stop or lessen an attack.
Questions
What is migraine prodrome?
It is the first phase of a migraine attack. It comes before the aura and the headache, and it can begin several hours or days before them, according to the American Migraine Foundation.
What are the symptoms of the migraine prodrome?
The American Migraine Foundation lists irritability, mood changes, yawning, fatigue, trouble sleeping, frequent urination, food cravings, nausea, sensitivity to light or sound, trouble concentrating, difficulty speaking or reading, neck pain or stiffness and hyperactivity.
How long does the prodrome last?
Sources differ. The American Migraine Foundation says several hours and sometimes days. Cleveland Clinic says it begins up to 24 hours before the headache. The formal headache classification uses 2 to 48 hours.
Is the prodrome the same as an aura?
No. The aura is usually a visual event that lasts 5 to 60 minutes. The prodrome is the earlier phase, with mood, appetite, yawning and neck signs.
Do all migraines have a prodrome?
Not every person notices one. The American Migraine Foundation says about 70 to 80% of people with migraine have a prodrome at the start of their attacks, and studies report different numbers.
Can you stop a migraine in the prodrome phase?
The American Migraine Foundation says treatment in this phase may stop or lessen an attack. Ask your doctor what that could look like for you.
Where the line comes in
If the first phase begins before the pain, the real question is how close your brain was to the edge when the day began.
There is a name for that edge. The Migraine Tipping Line™.
