A migraine is a neurological disease characterized by recurrent, often severe, headaches and a collection of other symptoms. It is much more than a typical headache.
Key Characteristics:
Pain: Typically described as a throbbing or pulsing pain, usually affecting one side of the head (though it can affect both).
Severity: The pain is often moderate to severe and can be debilitating, often worsening with physical activity.
Associated Symptoms: The pain is frequently accompanied by:
Nausea and/or vomiting.
Extreme sensitivity to light (photophobia) and sound (phonophobia).
Sometimes sensitivity to smell (osmophobia).
Duration: Attacks typically last from 4 to 72 hours.
The Four Phases of a Migraine (Though not everyone experiences all phases):
Prodrome (The Warning): Occurs hours or days before the headache. Symptoms can include mood changes (irritability or depression), food cravings, neck stiffness, frequent yawning, or increased urination.
Aura (Sensory Disturbances): Affects about 20-30% of people. It usually occurs just before or during the headache and lasts less than an hour. Auras are often visual (seeing flashes of light, zigzag lines, or blind spots) but can also involve tingling/numbness in the face or limbs, or difficulty speaking.
Headache (The Attack): The phase with the severe throbbing pain and associated symptoms.
Postdrome (The "Migraine Hangover"): Occurs after the headache subsides. The person may feel exhausted, drained, confused, or unusually refreshed.
Causes and Triggers:
The exact cause is complex and related to changes in brain activity, blood vessels, and nerve pathways. Genetics play a significant role. Triggers vary by individual but commonly include:
Hormonal Changes: Common in women around the menstrual cycle.
Stress and Anxiety.
Dietary Factors: Alcohol (especially red wine), aged cheeses, food additives (like MSG), and caffeine withdrawal.
Sensory Stimuli: Bright lights, loud noises, or strong smells.
Sleep Irregularities: Too much or too little sleep.
