Migraine: Symptoms, Diagnosis and Treatment

Overview

Migraine is a neurological condition, not just a headache. It is characterized by episodes of intense, often one-sided head pain accompanied by sensitivity to light, sound, and sometimes smell, along with nausea and other symptoms. Migraine affects approximately 12% of the population and is three times more common in women than men.

Migraine is now understood as a disorder of the nervous system involving abnormal brain activity, nerve pathways, and chemical imbalances. It involves the trigeminal nerve system and substances like CGRP (calcitonin gene-related peptide), which plays a key role in pain signaling and inflammation.

Migraine attacks can last from 4 to 72 hours if untreated and can be debilitating. Some people experience an 'aura' — visual disturbances, tingling, or other neurological symptoms — before or during an attack. Migraine can be episodic (fewer than 15 days per month) or chronic (15+ headache days per month).

Migraine is often underdiagnosed and undertreated. Many people who could benefit from preventive treatments don't receive them. The development of CGRP-targeting medications has been a major breakthrough, offering new options specifically designed for migraine prevention.

Symptoms

Common Symptoms

The Headache Phase

Intense, throbbing or pulsating pain — often on one side of the head, but can affect both sides
Pain that worsens with physical activity
Duration — 4 to 72 hours if untreated
Sensitivity to light (photophobia) — needing to be in a dark room
Sensitivity to sound (phonophobia)
Nausea and vomiting
Sensitivity to smells (osmophobia)

Aura (Approximately 25% of Migraine Sufferers)

Visual disturbances — flashing lights, zigzag lines, blind spots, or temporary vision loss
Sensory changes — tingling or numbness, often starting in the hand and spreading
Speech difficulties — trouble finding words or slurred speech
Lasts 5–60 minutes before the headache phase

Prodrome (Hours to Days Before)

Mood changes (irritability, depression, or euphoria)
Food cravings
Neck stiffness
Frequent yawning
Increased sensitivity to light or sound

Postdrome (After the Attack)

Exhaustion or 'migraine hangover'
Difficulty concentrating
Mood changes
Can last up to 48 hours

Triggers

Hormonal changes (menstruation, ovulation)
Stress or stress letdown
Sleep changes (too much or too little)
Certain foods (aged cheese, MSG, nitrates, chocolate, alcohol)
Skipping meals or dehydration
Weather changes
Bright or flickering lights
Strong smells

Diagnosis

How Migraine Is Diagnosed

Clinical Diagnosis

Migraine is diagnosed based on symptoms and medical history
There is no blood test or scan that confirms migraine
Imaging (MRI or CT) may be used to rule out other causes if red flags are present

Diagnostic Criteria (IHS/ICHD-3)

At least 5 attacks lasting 4–72 hours
Headache with at least 2 of: one-sided, pulsating, moderate-to-severe, worsened by activity
At least 1 of: nausea/vomiting, OR photophobia and phonophobia
Not attributed to another disorder

Medical Evaluation

Detailed headache history (frequency, duration, triggers, symptoms)
Neurological exam
Blood pressure check
Family history of migraine

When Imaging Is Needed (Red Flags)

Sudden, severe headache ('thunderclap')
New headache after age 50
Headache with neurological symptoms that don't resolve
Headache with fever or stiff neck
Headache after head trauma
Progressive or changing headache pattern

Headache Diary

Keeping a detailed diary is crucial for diagnosis and treatment
Track: when headaches start, pain location and intensity, symptoms, triggers, medications taken and their effect
This helps identify patterns and guides treatment decisions

Treatments

Treatment Approaches

Acute Treatment (During an Attack)

Triptans — sumatriptan, rizatriptan, and others; first-line for moderate-to-severe migraine
CGRP antagonists (gepants) — ubrogepant, rimegepant; newer option, fewer side effects
NSAIDs — ibuprofen, naproxen; for mild-to-moderate attacks
Acetaminophen — alone or combined with NSAIDs
Anti-nausea medications — metoclopramide, prochlorperazine
Ditans — lasmiditan; newer class, for acute treatment

Preventive Treatment

CGRP monoclonal antibodies — erenumab (Aimovig), fremanezumab (Ajovy), galcanezumab (Emgality); monthly injections, specifically designed for migraine prevention
Beta-blockers — propranolol, metoprolol
Anticonvulsants — topiramate, valproate
Antidepressants — amitriptyline, venlafaxine
Botox injections — for chronic migraine (15+ days/month), injected every 12 weeks
Oral CGRP antagonists (for prevention) — atogepant (Qulipta)

Lifestyle and Behavioral

Identify and avoid triggers — use a headache diary
Maintain regular sleep, meals, and hydration
Exercise regularly — moderate aerobic exercise can reduce frequency
Stress management — CBT, biofeedback, meditation
Supplements — magnesium, riboflavin (B2), and coenzyme Q10 have evidence for prevention

When to Consider Prevention

4+ migraine days per month
Migraines that significantly interfere with daily life
Acute medications not effective or overused
Patient preference

Important Notes

Medication overuse headache can occur with frequent use of acute medications (triptans, NSAIDs, pain relievers more than 10–15 days per month)
Discuss a comprehensive treatment plan with your doctor
CGRP-targeting treatments are a significant advance but not everyone responds

Your Care Plan

A step-by-step guide to navigating your condition, from finding the right doctors to advocating for the care you deserve.

Step 1: Doctors to See

Which Specialists to See

Primary Care Provider

Start here for initial evaluation and management
Can prescribe basic acute and preventive medications
Can order imaging if needed

Neurologist

Specialist in neurological conditions including migraine
For complex cases, chronic migraine, or when initial treatments aren't working
Can prescribe CGRP monoclonal antibodies and Botox

Headache Specialist (Neurologist with Headache Medicine Certification)

Subspecialist focused on headache disorders
For refractory or complicated migraine cases
Access to newest treatments and clinical trials

Pain Management Specialist

For chronic pain that is not well-controlled

Mental Health Professional

For stress management, CBT, or depression/anxiety related to migraine

Gynecologist (for menstrual migraine)

If migraines are strongly linked to menstrual cycle
Can discuss hormonal management options

Step 2: Advocate for Yourself

How to Advocate for Yourself

1. Keep a Detailed Headache Diary

Track: date/time, pain intensity (1–10), location, symptoms, triggers, medications taken and their effect
Use an app (like Migraine Buddy) or a notebook
This is the most important tool for diagnosis and treatment

2. Ask About Preventive Treatment

If you have 4+ migraine days per month, ask: 'Am I a candidate for preventive treatment?'
Ask specifically about CGRP-targeting medications — they're newer and specifically designed for migraine
Don't accept 'just take pain pills' as a complete treatment plan

3. Don't Accept 'It's Just a Headache'

Migraine is a neurological condition, not just a headache
It can be disabling — if your provider dismisses it, seek a neurologist
Ask: 'Is this migraine or another type of headache?'

4. Discuss All Treatment Options

Ask about both acute and preventive treatments
Ask about lifestyle changes, supplements (magnesium, B2, CoQ10), and behavioral therapies
If one treatment doesn't work, ask about alternatives — there are many options now

5. Watch for Medication Overuse

Taking acute medications more than 10–15 days per month can cause medication overuse headache
If you're using pain relievers frequently, discuss a preventive strategy

6. Consider a Specialist

If your migraines are frequent, severe, or not responding to treatment, ask for a neurologist referral
A headache specialist may be needed for complex cases
Don't wait years — early treatment can prevent progression to chronic migraine

Step 3: Your Action Plan

Your Step-by-Step Action Plan

Step 1: Start a Headache Diary (Week 1)

Track every headache: date, time, intensity, location, symptoms, triggers, medications and their effect
Note patterns related to your menstrual cycle if applicable
Use an app or notebook — consistency is key

Step 2: See Your Doctor (Week 2–3)

Bring your headache diary
Ask: 'Are these migraines? What type?'
Discuss both acute and preventive treatment options
Ask about CGRP-targeting medications if appropriate
Request a neurologist referral if migraines are frequent or severe

Step 3: Start Treatment (Week 3–6)

Take acute medications as prescribed at the first sign of a migraine
Start preventive medication if recommended — give it 6–8 weeks to work
Begin lifestyle changes: regular sleep, meals, hydration, exercise

Step 4: Identify and Manage Triggers (Week 4–8)

Review your diary for patterns
Address modifiable triggers (sleep, stress, meals, hydration)
Consider supplements (magnesium, B2, CoQ10) — discuss with your doctor
Start stress management (CBT, meditation, biofeedback)

Step 5: Evaluate and Adjust (Month 2–3)

Review your diary — are migraines less frequent or less severe?
If not, discuss alternative or additional treatments with your doctor
Ask about Botox or CGRP antibodies if appropriate

Step 6: Long-Term Management (Ongoing)

Continue your headache diary
Maintain lifestyle changes (sleep, exercise, stress management)
Take preventive medication consistently
Plan for attacks — have acute medication with you
See your neurologist regularly to adjust treatment as needed
