Migraine is a neurological condition that causes recurring attacks. A typical attack may include a moderate to severe headache, nausea, and sensitivity to light or sound. Some people also experience an aura before or during an attack. (National Health Service [NHS], 2026; MedlinePlus, n.d.)
Migraine vs. Headache: What’s the Difference?
Not all headaches are migraines, though people often use the terms interchangeably. A headache is a symptom — pain in the head or face that can be caused by dozens of things, from tension and dehydration to sinus congestion or eye strain. Migraine, on the other hand, is a distinct neurological disease in which headache is just one part of a larger cluster of symptoms.
Key differences:
- Nature of the pain — Tension-type headaches usually feel like a dull, constant pressure or tightness on both sides of the head. Migraine pain is typically throbbing or pulsating, often on one side, and tends to worsen with physical activity.
- Accompanying symptoms — A regular headache is often just pain, with little else. Migraine attacks commonly come with nausea, vomiting, and sensitivity to light and sound — symptoms that are rare with ordinary headaches.
- Aura — Some migraines are preceded or accompanied by aura (visual disturbances, tingling, numbness, or speech difficulty). This is unique to migraine and doesn’t occur with typical tension or sinus headaches.
- Duration and pattern — Tension headaches often resolve within a few hours and may respond quickly to simple pain relief. Migraine attacks typically last longer (4–72 hours untreated) and tend to recur in a pattern over a person’s life, often with identifiable triggers.
- Underlying cause — Most everyday headaches are secondary to something identifiable (stress, dehydration, poor posture, minor illness). Migraine has a strong genetic and neurological basis, meaning the tendency toward attacks is often inherited rather than caused by a single external factor.
Bottom line: All migraines involve headache, but not all headaches are migraines. If headaches are frequent, severe, disabling, or accompanied by nausea, visual changes, or sensitivity to light and sound, it’s worth discussing with a clinician to determine whether migraine — rather than a more common type of headache — is the underlying cause.
What causes it or increases the risk?
- Migraine has a strong biological and often genetic component
- Attacks may be triggered by stress, sleep changes, missed meals, hormonal changes, dehydration, alcohol, or excessive caffeine in some people
- triggers differ from person to person and are not the underlying cause of the disorder
Common signs and symptoms
- Throbbing or pulsating headache, often worse with movement
- Nausea or vomiting
- Sensitivity to light and sound
- Visual symptoms such as flashing lights or zigzag lines in migraine with aura
- Tingling, numbness, dizziness or speech difficulty can occur with aura
How it is diagnosed
Migraine is diagnosed clinically from the pattern of attacks and a neurological examination. Imaging is usually reserved for cases with an unusual pattern, abnormal examination or red flags suggesting another cause.
Treatment and management
- Acute treatment can include suitable pain medicines, anti-nausea medicines, triptans or newer migraine-specific medicines prescribed according to local availability and individual health needs
- Preventive medicines may be considered when attacks are frequent or disabling
- Regular sleep, meals, exercise, hydration and stress management can support treatment
- Frequent use of pain medicine can itself worsen headaches, so repeated use should be discussed with a clinician
Treatment choices depend on the person, severity, pregnancy status, other medical conditions, local resistance patterns where infection is involved, and current national guidance. Readers should not start, stop or share prescription medicines based only on an online article.
Possible complications
- Medication-overuse headache
- Lost work or school time
- Dehydration from repeated vomiting
- Rarely, complications such as persistent aura or migrainous infarction
Prevention and practical steps
- Identify personal triggers
- Keep regular sleep and meal times
- Stay hydrated
- Follow a clinician-approved preventive plan if attacks are frequent
When to seek urgent medical help
- A first or worst-ever sudden headache
- New weakness, facial droop, speech difficulty or loss of consciousness
- Headache with high fever and stiff neck
- New severe headache after injury
- A major change in a long-standing migraine pattern
Key takeaway
Migraine should be understood using the full pattern of symptoms, risk factors and appropriate testing. Early assessment is especially important when symptoms are severe, persistent, unusual or accompanied by the warning signs listed above. Reliable diagnosis and treatment come from qualified health professionals and current clinical guidance.
