Introduction
- Migraine is a neurological condition characterized by recurrent, moderate-to-severe headaches, often accompanied by other symptoms such as nausea, vomiting, and sensitivity to light and sound.
- Migraine is more common in women and can significantly impact daily life and productivity.
- Effective management includes identifying triggers, acute treatments for attacks, and preventive therapies to reduce the frequency and severity of episodes.
Types of Migraine
- Migraine Without Aura
- Most common type.
- Moderate-to-severe throbbing pain, often on one side of the head.
- Migraine With Aura
- Visual or sensory disturbances (e.g., flashing lights, zigzag lines, or tingling) precede the headache.
- Chronic Migraine
- Headache on 15 or more days per month, with at least 8 days having migraine features.
- Hemiplegic Migraine
- Rare type causing temporary paralysis or weakness on one side of the body.
- Menstrual Migraine
- Linked to hormonal changes during the menstrual cycle.
Causes and Triggers of Migraine
- Triggers
- Stress, lack of sleep, dehydration.
- Dietary factors: Alcohol, caffeine, processed foods.
- Environmental changes: Bright lights, loud sounds, strong odors.
- Hormonal fluctuations in women.
- Underlying Mechanisms
- Overactivation of the trigeminovascular system.
- Cortical spreading depression leading to aura.
- Imbalances in neurotransmitters, particularly serotonin.
Symptoms of Migraine
- Prodrome (Warning Phase)
- Fatigue, mood changes, cravings, or yawning hours to days before the headache.
- Aura (In Some Cases)
- Visual disturbances: Zigzag lines, blind spots.
- Sensory symptoms: Tingling or numbness.
- Headache Phase
- Throbbing or pulsating pain, often unilateral.
- Nausea, vomiting, and sensitivity to light (photophobia) or sound (phonophobia).
- Postdrome (Resolution Phase)
- Fatigue, confusion, and body aches after the headache subsides.
Complications of Migraine
- Medication Overuse Headache: Frequent use of pain relievers can worsen headaches.
- Stroke Risk: Slightly increased in migraines with aura, particularly in women using hormonal contraceptives.
- Chronic Migraine: Conversion from episodic to chronic headaches.
- Quality of Life Impact: Missed work or school and emotional distress.
Diagnosis of Migraine
- Clinical Assessment
- History of recurrent headaches with associated symptoms.
- Diagnostic Criteria (ICHD-3)
- At least five attacks fulfilling specific criteria for migraine without aura or two for migraine with aura.
- Exclusion of Other Causes
- Imaging (MRI or CT) to rule out structural brain issues in atypical cases.
- Headache Diaries
- Track frequency, duration, triggers, and associated symptoms.
