Learn what do neurologists look for in migraine diary reviews, from attack frequency and severity trends to rescue medication use and trigger patterns.
Understanding what do neurologists look for in migraine diary entries changes how you keep your log, and often changes what happens at your appointment. Most people walk in with a rough count of bad days, or a note on their phone that says something like "bad week." What your neurologist actually needs is structured, consistent data across months, not impressions.
This guide breaks down exactly what clinicians scan for, why each data point matters, and how to make sure your log does real work for you.
When a neurologist opens your log, they are not reading it like a journal. They are running a quick mental analysis, looking for signals that point toward a diagnosis, a pattern, or a treatment decision. Here is what gets their attention.
Monthly migraine days (MMDs) is the single most important number in your log. It is the foundation for classifying your migraine as episodic or chronic, and it directly influences which treatments are appropriate. Chronic migraine is generally defined as 15 or more headache days per month, with at least eight of those meeting migraine criteria.
Your neurologist will count MMDs across multiple months, not just the worst one. A single brutal month surrounded by lighter months tells a different story than a consistent pattern of 12 to 14 days every month for six months straight.
These are related but not the same. You might have four discrete migraine attacks in a month, but each one lasts three days, pushing your headache day count to 12. That frequency and duration pattern matters. It tells the clinician whether your attacks are long and infrequent or short and relentless, which informs both prevention strategy and acute treatment choices.
A single severity rating per attack is useful. A trend across months is much more useful. If your average severity was 7 out of 10 six months ago and is now consistently 9 out of 10, that trajectory is a signal, even if your attack count stayed the same. Severity scores help your neurologist evaluate whether a current treatment is working or whether something is getting worse.
Use a consistent scale, either 1 to 10 or a simple mild, moderate, severe, and apply it the same way every time.
How often you reach for acute medication is one of the first things a neurologist checks. Frequent rescue medication use, regardless of which type it is, raises the question of medication overuse headache, which can transform episodic migraine into a chronic daily pattern. Most guidelines flag use on 10 or more days per month as a potential concern for certain medication classes, and 15 or more days for others.
Your log does not need to track dosages in clinical detail, but it should record every day you took something for an attack. This data is often the piece that unlocks a new conversation about prevention. For more on how to structure what you record, see what to log in your migraine diary.
How long each attack lasts is separate from how many days you have. An attack that lasts four hours and one that lasts 72 hours are clinically very different, even though they each count as one attack. Duration also helps identify postdrome, the recovery phase after the headache resolves, which many people do not log but which contributes significantly to total disability.
Neurologists look for consistent triggers across many attacks, not isolated ones. If bright light appears as a trigger in 65 percent of your attacks, that is a meaningful finding. If you logged red wine once during a bad month, that is not enough to draw conclusions.
The most clinically relevant triggers tend to be hormonal (especially menstrual cycle timing), sleep disruption, and missed meals. Weather and stress appear frequently but are harder to control and harder to interpret.
Log what you suspect, but let your clinician decide what the pattern means. Avoid over-identifying triggers based on one or two data points.
Pain level is only one dimension of a migraine attack. Your neurologist also wants to know what the attack took from you. Did you miss work? Cancel plans? Stay in bed? That functional impact is what disability scales like the MIDAS score are designed to capture.
You can get a sense of your current disability burden using the MIDAS calculator. MIDAS scores help clinicians benchmark severity and track whether a treatment is actually improving your ability to function, not just changing pain scores.
An attack rated 6 out of 10 that still let you work from home is different from a 6 out of 10 that kept you in a dark room. Logging disability alongside pain gives a fuller picture.
A log with 90 days of complete entries is worth more than one with six months of spotty data. Neurologists need to see your migraine-free days as much as your attack days. If you only log when you have a headache, the log looks like you have headaches every day you logged, with no context.
Phrases like "really bad" or "not too bad" are hard to compare across months. Stick to numbers or defined categories. Mild, moderate, and severe with consistent personal definitions work well.
If you have head pain on Monday, feel okay Tuesday, then pain returns Wednesday, is that one attack or two? Log them as separate attacks if there was a clear pain-free window. Conflating them inflates duration and obscures the true pattern.
Aura, nausea, light sensitivity, and sound sensitivity are diagnostic data points. If your log only captures pain, your neurologist is missing part of the picture. These symptoms also help distinguish migraine from tension headache or other conditions.
For a deeper look at how clinicians actually interpret the data you bring in, how doctors use migraine data walks through the clinical decision process in more detail. And when you are preparing for an upcoming appointment, sharing your migraine log with your doctor covers how to present your data effectively.
The biggest mistake is not logging at all during good stretches. If you only open your tracking app when you have pain, you lose the baseline data that makes patterns visible.
Other common issues:
Mild attacks still count. They contribute to your monthly headache day total and they often carry useful trigger and pattern information.
Migraine Tracker: CGRP Log is built around exactly the data points covered here. It tracks monthly migraine days, severity trends, rescue medication use, and disability impact automatically, then formats that data into clinician-ready summaries and CGRP renewal reports you can bring directly to your appointment.

Neurologists focus on monthly migraine days, attack frequency, severity trends, how often you use rescue medication, how long attacks last, and how much disability each attack causes. Patterns across weeks and months matter more than any single entry.
