Overview: Migraines are severe, recurrent headaches often accompanied by other symptoms such as nausea, vomiting, and sensitivity to light and sound. Migraines are a neurological condition affecting approximately 12% of the population, with higher prevalence in women. Migraines can significantly impact quality of life and work productivity.
Types of Headaches
- Migraine with Aura: Visual or sensory disturbances precede the headache
- Migraine without Aura: Headache without preceding symptoms (most common)
- Chronic Migraine: 15 or more headache days per month
- Status Migrainosus: Migraine lasting > 72 hours
Migraine Phases
- Prodrome (24 hours before): Mood changes, food cravings, fatigue
- Aura (20-60 minutes): Visual disturbances, numbness, tingling
- Headache Phase (4-72 hours): Throbbing pain, usually one-sided
- Postdrome (24 hours after): Fatigue, mood changes, difficulty concentrating
Symptoms
- Throbbing or pulsating headache
- Pain usually on one side of head
- Nausea and vomiting
- Sensitivity to light (photophobia)
- Sensitivity to sound (phonophobia)
- Sensitivity to smell
- Blurred vision
- Dizziness
Triggers (Common)
- Hormonal changes (menstrual cycle, oral contraceptives)
- Stress and anxiety
- Sleep changes
- Skipped meals
- Caffeine withdrawal
- Certain foods (aged cheese, processed meats, chocolate, citrus)
- Alcohol (especially red wine)
- Environmental factors (bright lights, strong smells, weather changes)
- Physical exertion
Risk Factors
- Family history (70% of migraine patients have family history)
- Female gender (3:1 ratio)
- Age (typically start between 10-40 years)
- Hormonal factors
- Stress
- Sleep disorders
- Obesity
Diagnosis
- Detailed history of headache characteristics
- Neurological examination
- Headache diary to identify patterns and triggers
- Brain imaging (MRI or CT) if symptoms are atypical or progressive
- Blood tests to rule out other conditions
Treatment Options
- Acute Treatment (for individual migraines):
- Triptans (sumatriptan, rizatriptan, naratriptan)
- NSAIDs (ibuprofen, naproxen)
- Combination medications
- Anti-nausea medications
- Rest in dark, quiet room
- Preventive Treatment (for frequent migraines):
- Beta-blockers (propranolol)
- Tricyclic antidepressants (amitriptyline)
- Anti-seizure medications (topiramate, valproic acid)
- CGRP antagonists (newer class of preventive medications)
- Botox injections (for chronic migraine)
- Lifestyle Modifications:
- Identify and avoid triggers
- Regular sleep schedule
- Stress management techniques
- Regular exercise
- Healthy diet
- Limit caffeine and alcohol
- Stay hydrated
- Relaxation techniques (yoga, meditation)
Prognosis
With appropriate treatment, migraine frequency and severity can be significantly reduced. Many patients achieve 50% or greater reduction in migraine days with preventive treatment. Some patients may experience remission, especially if triggers are identified and avoided.
