In short
Migraine isn't just a bad headache — it's a distinct neurological condition with recognizable subtypes, common triggers, and a treatment approach that splits cleanly into stopping an attack and preventing the next one.
Emergency if: A headache that comes on suddenly and is extremely painful; weakness or numbness on one side of the face or body, or trouble speaking; loss of vision or blurred or double vision that is new for you; drowsiness, confusion or a seizure; a headache with a very high fever, a stiff neck or a rash; or a headache after a recent head injury: call emergency services now. The NHS lists these as reasons to get help straight away, even in someone who already has migraine.

What Sets Migraine Apart From a Regular Headache
Migraine is a neurological condition that causes attacks of moderate to severe headache, often on one side of the head, along with symptoms such as nausea, vomiting, and sensitivity to light and sound. It tends to run in families and often begins in adolescence or early adulthood.
What distinguishes migraine from a tension headache is both the intensity and the accompanying symptoms; a migraine attack can be disabling enough to require lying down in a dark, quiet room until it passes.
02
With Aura, Without Aura, and Chronic Migraine
Migraine with aura involves temporary sensory disturbances, most often visual changes like flashing lights, zigzag lines, or blind spots, that typically develop before or alongside the headache. Migraine without aura, the more common type, has the same headache and associated symptoms but no preceding sensory warning.
Chronic migraine is defined by headache on fifteen or more days a month for at least three months, with at least eight of those days having migraine features, and it often requires a different, more comprehensive treatment strategy than occasional episodic migraine.
03
Common Triggers
Triggers vary from person to person but frequently include lack of sleep, skipped meals, dehydration, stress or the letdown after stress, hormonal changes across the menstrual cycle, certain foods or alcohol, and changes in weather or barometric pressure. Bright lights and strong smells can also set off an attack in some people.
Keeping a simple log of headache days alongside sleep, meals, and stress can help identify a person's individual pattern, since triggers are often specific to the individual rather than universal.
04
Treatment: Stopping an Attack Versus Preventing One
Acute treatment, taken as soon as an attack starts, aims to stop the headache and associated symptoms in progress, using options ranging from over-the-counter pain relievers to migraine-specific prescription medications that act on the pathways involved in an attack. Acting early in an attack generally works better than waiting.
Preventive treatment is a separate, ongoing strategy considered when migraines are frequent or significantly disabling, using daily medications, or newer options given less often, to reduce how often attacks happen in the first place. A neurologist can help decide when someone has crossed the threshold where preventive treatment makes sense.
05
Living With Migraine, and the Outlook
Migraine tends to fluctuate over a lifetime, often improving with age or around major hormonal changes, though the course differs for everyone. Consistent sleep, regular meals, hydration, and stress management are simple but genuinely effective habits that reduce attack frequency for many people.
With the right combination of trigger management, acute treatment, and, when needed, preventive medication, most people with migraine achieve meaningfully better control over their attacks and daily life. A neurologist is the right specialist when migraines are frequent, severe, or not responding to initial treatment.
Migraine: how fast to act
Routine — see a doctor
Attacks more than once a week, attacks getting worse or harder to control, or attacks that come before or during your periods: book a visit with a doctor to talk about preventive treatment.
Same-day — call promptly
A migraine attack that has lasted longer than 72 hours, aura that lasts longer than 1 hour, or a migraine while pregnant or soon after giving birth: see a doctor today. The NHS lists these as reasons for urgent advice.
Emergency — act now
A headache that comes on suddenly and is extremely painful; weakness or numbness on one side of the face or body, or trouble speaking; loss of vision or blurred or double vision that is new for you; drowsiness, confusion or a seizure; a headache with a very high fever, a stiff neck or a rash; or a headache after a recent head injury: call emergency services now. The NHS lists these as reasons to get help straight away, even in someone who already has migraine.
