Migraine
A common neurological disorder causing recurrent, often disabling headaches.
Migraine is a neurological disorder characterized by moderate-to-severe headaches, often one-sided and pulsating, accompanied by nausea, light sensitivity, and sound sensitivity. It affects approximately 14% of the global population, making it the third-most disabling condition affecting the nervous system and a leading cause of disability worldwide.

Lore & Background
Migraine attacks have multiple phases. The premonitory phase can start 48 hours before the headache, with symptoms like altered mood, fatigue, and food cravings. The aura phase, experienced by about 30% of those with migraine, involves reversible neurological disturbances—most often visual, such as scintillating scotoma—lasting 5 to 60 minutes. The pain phase typically involves moderate-to-severe throbbing pain, often one-sided, and can last up to 72 hours. The postdrome, or 'migraine hangover,' follows the headache and may include tiredness, difficulty concentrating, and mood changes.
Reader's Guide
Migraine is believed to result from a combination of genetic, environmental, and neurological factors that affect nerve cell activity and brain chemical signals. Attacks are theorized to occur when the brain exceeds an individual's sensitivity threshold. Management includes lifestyle changes to identify triggers, such as stress management, regular sleep, and exercise. Acute treatment for mild to moderate attacks begins with over-the-counter pain relievers; triptans are first-line for moderate to severe attacks. Preventive medications include beta blockers, anticonvulsants, certain antidepressants, and gepants. Opioids should not often be prescribed. Migraine is associated with neuropsychiatric disorders including depression, anxiety, and sleep disorders. Its high prevalence and disabling nature make it a significant public health concern, particularly for women, who experience more frequent and longer attacks beginning in puberty and peaking during perimenopause.
Did You Know?
- Migraine attacks can last longer than 72 hours despite treatment, a condition known as status migrainosus.
- About 30% of people with migraine experience aura, which are reversible neurological disturbances often visual in nature.
- Frequent use of pain medications can worsen migraines and lead to medication overuse headache.
- Migraine is associated with neuropsychiatric disorders such as major depression, bipolar disorder, and anxiety disorders.
Frequently Asked Questions
What is Migraine?
Migraine is a neurological condition that produces recurring episodes of intense, typically one-sided, throbbing head pain. These episodes are frequently paired with nausea, sensitivity to light and noise, and can last anywhere from four hours up to three days in adults.
How widespread is Migraine?
Roughly 14% of people worldwide—about 1.16 billion individuals—deal with this condition at some point. It ranks as the third most disabling nervous-system disorder and is a top contributor to global disability overall.
Who does Migraine hit hardest?
Women are disproportionately affected, experiencing up to four times as many episodes as men during their 30s and 40s. Hormonal shifts are a well-known factor behind this gap.
What sets off a Migraine episode?
Common triggers include poor or interrupted sleep, going too long without eating, and hormonal fluctuations. About 30% of people with the condition also report a visual or sensory 'aura' before the pain phase begins.
Is Migraine inherited?
Family history plays a significant role, with heritability estimates ranging from roughly 34% to 64%. This means a genetic component is a major piece of the puzzle, though environmental factors also contribute.
