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.

When to Seek Emergency Care

  • Sudden, severe "thunderclap" headache
  • Headache with fever, stiff neck, confusion
  • Headache with weakness, numbness, vision changes
  • Headache after head injury
  • Worsening headache pattern
