Migraine: A Complete Guide for International Patients in Shanghai

Introduction

Migraine is far more than a bad headache. It is a complex neurological disorder that affects approximately 1 billion people worldwide, making it one of the most prevalent and disabling conditions on the planet. A migraine attack can last anywhere from 4 to 72 hours and is often accompanied by nausea, vomiting, and extreme sensitivity to light and sound — rendering sufferers unable to work, study, or carry out daily activities.

For international patients and expatriates living in Shanghai, migraine can be particularly challenging to manage. Jet lag, irregular sleep, high-stress work environments, air quality fluctuations, and unfamiliar food and drink can all act as triggers. Accessing specialist neurological care in a foreign healthcare system adds another layer of complexity. This guide provides a comprehensive overview of migraine — from understanding the condition to finding the right treatment and specialist care in Shanghai.

What Is a Migraine?

Migraine is a neurological disorder characterized by recurrent attacks of moderate-to-severe headache, typically on one side of the head (unilateral), with a pulsating or throbbing quality. Attacks are often accompanied by nausea, vomiting, and heightened sensitivity to light (photophobia) and sound (phonophobia).

Migraine is not simply a headache — it involves complex changes in brain chemistry, nerve pathways, and blood vessels. The exact mechanisms are not fully understood, but dysregulation of the trigeminal nerve system and the release of calcitonin gene-related peptide (CGRP) play central roles in migraine pathophysiology.

Types of Migraine

• Migraine without Aura (Common Migraine): The most prevalent type. Attacks occur without preceding neurological symptoms. Characterized by unilateral, pulsating headache lasting 4–72 hours, with nausea and/or light/sound sensitivity.
• Migraine with Aura (Classic Migraine): Approximately 25–30% of migraine sufferers experience aura — transient neurological symptoms that typically precede the headache by 20–60 minutes. Aura most commonly involves visual disturbances (zigzag lines, blind spots, flashing lights) but can also include sensory symptoms (tingling, numbness) or speech difficulties.
• Chronic Migraine: Defined as headache occurring on 15 or more days per month for more than 3 months, with at least 8 days per month meeting migraine criteria. Requires a different treatment approach from episodic migraine.
• Hemiplegic Migraine: A rare form where aura includes temporary motor weakness or paralysis on one side of the body. Can mimic stroke and requires urgent evaluation.
• Vestibular Migraine: Characterized by episodes of vertigo, dizziness, and balance problems, with or without headache. An underdiagnosed condition that is increasingly recognized.
• Menstrual Migraine: Attacks that occur in close association with menstruation, driven by fluctuations in estrogen levels.

The Four Phases of a Migraine Attack

Understanding the full migraine cycle helps patients recognize early warning signs and intervene promptly:

• Prodrome (hours to days before): Subtle warning signs including mood changes, food cravings, neck stiffness, increased urination, yawning, and fatigue.
• Aura (if present, 20–60 minutes before headache): Transient neurological symptoms, most commonly visual. Fully reversible within 60 minutes.
• Headache Phase (4–72 hours): Moderate-to-severe unilateral throbbing pain, worsened by physical activity, accompanied by nausea, vomiting, photophobia, and phonophobia.
• Postdrome (“migraine hangover”, up to 48 hours after): Fatigue, cognitive fog (“brain fog”), mood changes, and residual head sensitivity. Often overlooked but significantly impacts quality of life.

Common Triggers

Migraine triggers vary between individuals. Identifying and managing your personal triggers is a key part of long-term management. Common triggers include:

• Sleep disruption: Both too little and too much sleep; jet lag is a significant trigger for international travelers and expats
• Stress: High-pressure work environments, emotional stress, and “letdown” migraines after periods of stress
• Hormonal changes: Menstruation, ovulation, oral contraceptives, menopause
• Dietary triggers: Alcohol (especially red wine and beer), caffeine (both excess and withdrawal), aged cheeses, processed meats, MSG, skipping meals, and dehydration
• Environmental factors: Bright or flickering lights, strong smells, loud noise, weather changes, and air pressure fluctuations
• Shanghai-specific triggers: Air pollution (PM2.5), strong cooking smells, MSG-heavy cuisine, irregular meal schedules during business travel, and high workplace stress
• Physical factors: Intense exercise, poor posture, neck tension
• Medications: Medication overuse headache (MOH) — taking acute pain relief medications on more than 10–15 days per month can paradoxically worsen and perpetuate headache

Diagnosis

Migraine is a clinical diagnosis — there is no definitive blood test or imaging finding that confirms it. Diagnosis is based on a detailed history and the International Headache Society (IHS) diagnostic criteria.

A neurologist will typically:

• Take a comprehensive headache history (frequency, duration, character, associated symptoms, triggers, family history)
• Perform a neurological examination
• Order brain MRI or CT scan to rule out secondary causes of headache (tumors, vascular malformations, intracranial hypertension) — particularly important for new-onset severe headache, headache with neurological symptoms, or headache that has changed in character
• Consider blood tests to exclude other conditions

A headache diary — recording attack frequency, duration, severity, triggers, and medication use — is invaluable for diagnosis and treatment planning. Many smartphone apps are available for this purpose.

Treatment

Acute (Abortive) Treatment

The goal is to stop or reduce the severity of an attack as quickly as possible. Treatment is most effective when taken early in the attack.

• Simple analgesics: Aspirin, ibuprofen, naproxen, or paracetamol (acetaminophen). Effective for mild-to-moderate attacks. Available over the counter in China.
• Triptans: The gold standard for moderate-to-severe migraine. Selective serotonin (5-HT1B/1D) receptor agonists that constrict blood vessels and block pain pathways. Sumatriptan, rizatriptan, zolmitriptan, and others are available in China by prescription. Most effective when taken at the first sign of headache.
• Anti-emetics: Metoclopramide or domperidone to relieve nausea and improve absorption of oral medications.
• Ergotamines: Older agents, less commonly used due to side effect profile, but still available.
• Gepants (CGRP receptor antagonists): Newer acute treatments (ubrogepant, rimegepant) with a favorable side effect profile. Availability in China is expanding.
• Lasmiditan: A newer acute treatment targeting the 5-HT1F receptor. Availability in China is limited.

Important: Avoid taking acute medications on more than 10–15 days per month to prevent medication overuse headache (MOH).

Preventive (Prophylactic) Treatment

Preventive therapy should be considered when attacks are frequent (≥4 per month), prolonged, severely disabling, or not adequately controlled by acute treatment. The goal is to reduce attack frequency, severity, and duration by at least 50%.

• Beta-blockers: Propranolol and metoprolol are first-line preventive agents. Well-established efficacy and widely available in China.
• Topiramate: An anticonvulsant with strong evidence for migraine prevention. Available in China.
• Amitriptyline: A tricyclic antidepressant effective for migraine prevention, particularly in patients with comorbid depression or insomnia.
• Valproate: Effective but requires monitoring; not recommended in women of childbearing potential.
• Flunarizine: A calcium channel blocker widely used in Asia for migraine prevention; highly effective and commonly prescribed in China.
• CGRP monoclonal antibodies (anti-CGRP mAbs): A major advance in migraine prevention. Monthly or quarterly injections (erenumab, fremanezumab, galcanezumab) with high efficacy and excellent tolerability. Availability in China is growing; CMCS can assist with access.
• OnabotulinumtoxinA (Botox): Approved for chronic migraine prevention. Administered as injections every 12 weeks by a trained neurologist. Available at leading Shanghai hospitals.

Non-Pharmacological Approaches

• Biofeedback and relaxation therapy
• Cognitive behavioral therapy (CBT): Particularly effective for stress-related migraine
• Acupuncture: Evidence supports acupuncture as an effective preventive treatment; widely available in Shanghai through both TCM and integrated medicine departments
• Neuromodulation devices: Non-invasive devices targeting the vagus nerve or trigeminal nerve (e.g., Cefaly, gammaCore). Availability in China is limited but growing.
• Lifestyle optimization: Regular sleep schedule, consistent meal times, adequate hydration, stress management, and regular moderate exercise

Migraine & Women’s Health

Migraine disproportionately affects women, with a 3:1 female-to-male ratio. Key considerations:

• Menstrual migraine: Attacks around menstruation are often more severe and longer-lasting. Mini-prophylaxis with NSAIDs or triptans around the expected period can be effective.
• Oral contraceptives: Combined oral contraceptives can worsen migraine with aura and are associated with a small but increased risk of ischemic stroke in this group. Discuss with your neurologist and gynecologist.
• Pregnancy: Many women experience improvement in migraine during pregnancy (particularly the second and third trimesters). Medication choices are significantly restricted during pregnancy — specialist guidance is essential.
• Menopause: Migraine patterns often change around menopause; some women improve, others worsen.

Living with Migraine in Shanghai

Practical strategies for managing migraine as an international patient in Shanghai:
