Is it normal to feel depressed after a migraine?

Yes. Mood change is listed among the non-headache symptoms of the postdrome phase in ICHD-3, alongside fatigue, difficulty concentrating, and neck stiffness. It typically arrives as the head pain resolves and clears within 24 to 72 hours. If the low persists past that window or deepens across weeks, that's outside the postdrome pattern and worth raising with a clinician.

How long does the mood crash after a migraine last?

Usually inside the same 24 to 72 hour postdrome window as the fatigue and brain fog, and often shorter. The defining feature isn't how bad it feels, it's that it resolves on its own, keyed to when the attack ended, without any change in medication or circumstance.

How do I tell postdrome mood from depression?

Timing. Log your mood daily for a couple of months and mark when each attack ends. Postdrome mood clusters in the hours after attack resolution and lifts by itself. A mood disorder shows up on attack-free days too and doesn't track the attack cycle. Both can be present at once, which is exactly why the timestamps are useful to your prescriber.

What is the "migraine high" or post-attack euphoria?

Some people get the opposite of the crash: a bright, wired, unusually clear stretch right after an attack clears, sometimes with a burst of energy that outruns their actual reserves. It's part of the same postdrome spectrum and it's the least reported, because patients rarely think to mention feeling good.

Should I tell my neurologist about mood changes after attacks?

Yes, and bring dates. Attack duration reported as pain-only undercounts your actual disability, and preventive treatment decisions get made on that picture. Saying "the low mood and fog run about a day and a half past the headache, here are the last ten attacks" gives a specialist something to work with that "I've been down lately" doesn't.

The emotional crash after a migraine isn't depression. It's postdrome.

Your post-migraine mood crash has a clock, and that changes what it is

Mood change is a documented phase of the attack, not a separate diagnosis. The difference is timing, and no tracker is capturing it.

The dish in the sink

Your headache broke around two in the afternoon. By seven you're standing at the sink crying about a dish, and it isn't about the dish.

Or you're not crying at all. You're flat. Low voltage. Snapping at whoever walks into the kitchen, running a quiet internal audit of everything wrong with your life, while the overhead light is still slightly too bright and your neck is still stiff enough that you keep rolling it without noticing.

Tomorrow you'll be fine.

That last part is why none of this ever reaches the appointment. By the time you're sitting across from your neurologist, the crash has resolved and what you remember is the head pain, so head pain is what you report. The mood gets filed somewhere else entirely: your GP, a nine-question screener, a therapist who reasonably assumes chronic pain is the cause, sometimes a prescription that has nothing to do with migraine.

The crash has a clock

Postdrome mood change is time-locked to the attack. It arrives as the head pain lets go, it runs somewhere inside the 24 to 72 hours after, and it lifts on its own without any change in dose, sleep, therapy, or circumstance.

Mood disorder doesn't behave that way. It doesn't reliably start four hours after your triptan works and end by Thursday lunch.

So two people can describe an identical Tuesday evening, in identical words, and be describing different phenomena. What separates them isn't severity. It's timing. Plot the low against attack end and the shape either tracks the attack cycle or it scatters across days when nothing neurological happened at all.

None of that requires a new theory of migraine. It requires a timestamp.

Why searching "depression after migraine" returns the wrong answer

Type that phrase into anything and you get chronic-illness mental health content. Pain is depressing. Unpredictability is depressing. Losing days to a condition your employer half believes is depressing. All of that is true, and the comorbidity between migraine and mood disorder is well documented, and none of it answers the question the person actually typed.

The dominant framing treats the mood as downstream of the disease burden: you feel bad because migraine has made your life smaller. That's a reaction. Reactions don't run to a schedule.

What that framing can't account for is the timing signature, or the third presentation nobody warns you about, which is the strange bright wired hour some people get after an attack clears, and which fits reactive-sadness models not at all.

The cost of the misread lands in one place: the mood gets treated as a standing trait rather than as part of the attack, so the attack never gets credited with it, and the treatment conversation never touches the actual driver.

What the clinical record says

ICHD-3 treats the postdrome as a phase of the migraine attack, not as an aftermath, and lists non-headache symptoms including tiredness, difficulty concentrating, neck stiffness, and mood change. The app's exported clinical summary describes postdrome citing ICHD-3 and Bose & Goadsby (2016): "Per ICHD-3 + Bose & Goadsby (Neurology, 2016), migraine has a fourth phase (postdrome) that can disable the patient for hours to 3 days after the headache resolves. Symptom cluster: fatigue, cognitive impairment, residual photophobia, mood changes." The phrase used is the plural "mood changes," not the singular "mood change."

The prevalence work backs it up. Giffin and colleagues ran an electronic diary study published in Neurology in 2016 and found the large majority of patients reported at least one non-headache symptom during postdrome. Kelman's earlier Cephalalgia series of 893 patients put postdrome at roughly two thirds, with an average duration measured in tens of hours rather than a quick fade. Kelman 2006 study found postdrome symptoms occurred in 68% of migraine patients. ([source](https://pubmed.ncbi.nlm.nih.gov/16426278/))

And the mood piece isn't one thing. There are three presentations, they look nothing alike, and each one gets misfiled in a different direction.

24 to 72h

typical window in which postdrome symptoms resolveICHD-3 postdrome description

The three postdrome mood presentations as described in the postdrome literature, ranging from fatigue and low mood to a lifted, almost euphoric sense of relief once the attack passes.
Presentation	What it looks like	When it shows up	What it gets misread as
Irritability	Short fuse, noise intolerance, snapping at people you don't want to snap at, needing the room quiet and dim	As head pain resolves, often the same evening	A personality problem, or anxiety, or "you're always like this after"
Low affect	Flat, tearful, heavy, an internal audit of everything wrong, no energy for anything you normally like	First 24 hours after attack end, sometimes into day two	Depression, or reasonable sadness about being sick
Post-attack euphoria	Bright, wired, unusually clear and social, a burst of doing that outruns your actual energy	Immediately post-attack, often short	Nothing at all, because patients rarely think to report feeling good

A month, reconstructed

Take an ordinary month with four attacks. Nothing dramatic.

On paper, in the tracker, it's four rows: date, pain score, aura yes or no, medication taken, done. What actually happened is that on the evening of the 3rd you cancelled dinner and told the friend you were "just in a mood." On the 11th you had the argument about the dishwasher. On the 18th you sat in the car in the parking lot for twenty minutes before going in. On the 25th you cleaned the whole kitchen at ten at night and felt terrific.

Four incidents, in four different mental folders, none of them tagged migraine.

Now line them up against attack end. Every one falls inside 36 hours of a headache resolving. The month wasn't four headaches and a rough patch. It was four attacks, each with a phase that outlasted the pain, and the only reason it looked like a rough patch is that the pain is the only part anything recorded.

What changes if you time-stamp it

Three things change, and only one of them is about medication.

You stop grading yourself for the 11th. The argument about the dishwasher was a symptom with a mechanism and an end time, which is a different thing to carry than evidence of who you are.

Your household gets a forecast instead of a mystery. "The day after is usually rough" is a sentence a partner can plan around.

And your neurologist gets attack duration that reflects the attack. A patient who reports twelve hours of pain and a patient who reports twelve hours of pain plus thirty hours of a mood floor and no cognitive bandwidth are not describing the same disability, and preventive decisions are made on that picture. The postdrome burden is frequently the part that costs the work day.

This is additive, not subtractive. Timestamps don't overwrite a diagnosis you already have.

This is additional data, not a re-diagnosis

Migraine and mood disorders co-occur often, and a time-locked postdrome crash does not mean an existing depression or anxiety diagnosis was wrong. Plenty of people have both, and the postdrome window can sit on top of a baseline. Never stop or change a psychiatric medication based on a pattern you found in a tracker. Bring the pattern to the prescriber instead. And treat anything that doesn't fit the clock as its own signal: mood that persists past 72 hours after attack end, deepens across weeks, or involves thoughts of self-harm is not postdrome resolving, and it warrants a same-week call to a clinician. In the US, the 988 Suicide and Crisis Lifeline is available by call or text.

The field that doesn't exist

Here's the practical reason this data never reaches anyone: the trackers stop logging when the pain stops.

Open the mainstream migraine apps and the flow is built around attack entry. Onset, intensity, triggers, medication, relief. Mood, where it exists at all, sits on that same entry screen, which means you're rating it while your head hurts, before the crash has happened. Nothing prompts you the next evening.

So the single most under-reported phase of the attack is also the one phase nobody's app asks about, and the result is a fifteen-minute appointment built entirely from the hours the patient was in pain.

Postdrome logs the after. Mood sits in the post-attack window alongside fatigue, brain fog, and residual photophobia, on a timeline that keeps running after the headache ends, so what you show your neurologist is the whole attack instead of its loudest hour.

Postdrome was built around the 24 to 72 hours the other trackers treat as over. Mood, fatigue, brain fog, and residual photophobia get logged on a continuous timeline keyed to attack end, not to attack start, so the pattern is visible before you're in the room trying to remember it. Aura Mode keeps entry possible when you can't focus on a screen. Everything stays on your device, exports cleanly for an appointment, and the price is paid once.
