Overview of #406 – Migraine, cluster headache, and tension headache: symptoms, causes, prevention, and treatment

Peter Attia interviews headache specialist Brian Grosberg, M.D. about the full landscape of headache disorders, with a strong focus on migraine, plus practical distinctions from tension-type headache and cluster headache. The conversation covers how headaches are diagnosed without biomarkers, why migraine is so often underrecognized, how genetics, hormones, sleep, stress, and lifestyle shape risk, and the major treatment categories available today—from classic medications to CGRP-targeted therapies, Botox, and neuromodulation devices.

Main Takeaways

  • Headache medicine is under-taught in medical training despite headaches being among the most common neurologic complaints.
  • Migraine is not “just a bad headache”—it is a neurologic disease with phases, triggers, disability, and major societal burden.
  • Women are affected about 3x more often than men, and migraine often fluctuates with hormonal transitions such as puberty, menstruation, pregnancy, perimenopause, and menopause.
  • Cluster headache is far rarer than migraine but can be dramatically more painful and often requires urgent, multi-pronged treatment.
  • Lifestyle factors matter, but they do not “cause” migraine on their own; they act as triggers or risk modifiers in genetically susceptible people.
  • Headache diaries are one of the most useful tools for diagnosis and treatment selection.
  • Newer treatments—especially CGRP therapies—have significantly improved care for many patients, though access and cost remain major barriers.

How Headaches Are Classified

Primary vs. Secondary Headaches

  • Primary headaches are headache disorders in themselves, not caused by another disease.
    • Main examples discussed:
      • Migraine
      • Tension-type headache
      • Cluster headache
  • Secondary headaches are caused by something else, such as:
    • Brain tumor or aneurysm
    • Medication overuse
    • Caffeine withdrawal
    • Infection, inflammation, vascular problems, or CSF leak

Why Diagnosis Is Hard

  • There is no biomarker, lab test, or imaging result that reliably “proves” a migraine.
  • Diagnosis depends heavily on a careful history:
    • Location
    • Quality of pain
    • Speed of onset
    • Duration
    • Associated symptoms
    • Disability
    • Pattern over time

Migraine: What It Looks Like

Core Features

Migraine is typically defined by:

  • At least 5 lifetime attacks
  • Attacks lasting 4 to 72 hours
  • Plus 2 of 4 main pain features:
    • Often one-sided
    • Pulsating/throbbing
    • Moderate to severe
    • Worsened by or causing avoidance of routine activity

Common associated symptoms:

  • Light sensitivity
  • Sound sensitivity
  • Nausea/vomiting
  • Activity intolerance
  • In some cases, autonomic symptoms like tearing, eye redness, nasal congestion, or runny nose

Migraine Phases

Dr. Grosberg emphasizes that migraine is a process, not just the pain phase:

  • Premonitory/prodrome phase
    • Yawning
    • Food cravings
    • Fatigue
    • Irritability
    • Neck stiffness
    • Light sensitivity
  • Aura occurs in about 25–33% of patients
    • Usually visual
    • Gradual onset over 5–60 minutes
    • Can include zigzags, spots, blind spots, or partial visual loss
  • Headache phase
    • Pain plus sensory and autonomic symptoms
  • Postdrome
    • “Migraine hangover”
    • People feel drained or not back to normal for hours to days
  • Interictal burden
    • Anxiety and planning pressure between attacks, because patients live with uncertainty about when the next migraine will strike

Important Clinical Clues

  • Allodynia is common in migraine:
    • Painful sensitivity to normally non-painful stimuli
    • Examples: brushing hair, ponytails, hats, glasses
  • Allodynia may signal central sensitization
  • If migraine treatment is delayed until allodynia develops, some meds—especially triptans—may work less well

Migraine Risk Factors and Triggers

Genetic and Hormonal Influences

  • Migraine is highly heritable and polygenic
  • The nervous system in migraine patients appears more hyperexcitable
  • Hormonal transitions often affect migraine:
    • Puberty
    • Menstruation
    • Pregnancy
    • Lactation
    • Perimenopause
    • Menopause
  • About:
    • 2/3 of women with migraine have perimenstrual attacks
    • <10% have pure menstrual migraine
    • Around 50% have menstrual-related migraine

Common Modifiers / Triggers

Triggers are not the root cause; they elicit attacks in susceptible people. Common examples:

  • Changes in weather / barometric pressure
  • Stress “letdown” after a high-stress period
  • Sleep disruption or sleep apnea
  • Skipped meals / irregular eating
  • Dehydration
  • Alcohol
  • Certain foods
  • Overuse of acute pain medication
  • Mood disorders
  • Obesity
  • Other pain disorders

Obesity and Migraine

  • Obesity meaningfully increases risk, especially with more severe obesity
  • Dr. Grosberg notes:
    • Morbid obesity is associated with about a 5x higher risk of more frequent migraine
    • Even obesity itself roughly doubles risk
  • Weight loss can improve migraine in some patients

The Burden of Migraine

  • Migraine affects about 12% of the population
    • Roughly 1 billion people worldwide
    • About 45 million in the U.S.
  • It is disproportionately common in women:
    • About 18% of women may be affected
  • Economic burden is enormous:
    • Lost productivity
    • Absenteeism
    • Presenteeism — being at work but functioning poorly
  • Chronic migraine is especially disabling:
    • 15+ headache days/month
    • Seen in about 1–2% of the population

Tension-Type Headache

  • The most common headache people experience
  • Typically:
    • Bilateral
    • Mild to moderate
    • Non-throbbing
    • No nausea
    • At most, light or sound sensitivity—not both
  • Often feels like pressure or tightness involving the head, neck, or face
  • Can still be disabling, especially if it becomes chronic or frequent
  • May respond to simple OTC treatments like acetaminophen, but only if the diagnosis is correct

Cluster Headache

Defining Features

Cluster headache is:

  • Rare, but extremely severe
  • More common in men
  • Often described as one of the most painful disorders known

Typical presentation:

  • Severe pain behind or around one eye
  • Usually one-sided
  • Peaks quickly, often within 5–15 minutes
  • Attacks last 15 minutes to 3 hours
  • Can happen:
    • Several times per day
    • In clusters lasting weeks to months
    • Episodically or chronically

Hallmark Symptoms

  • Tearing
  • Eye redness
  • Nasal congestion / runny nostril
  • Eyelid droop
  • Intense restlessness
    • Unlike migraine, where patients usually want to lie still in a dark room

Misdiagnosis Risk

Cluster headache is often mistaken for:

  • Sinus infection
  • Allergies
  • Dental problems

This can lead to unnecessary antibiotics, allergy treatment, or even dental/sinus procedures.

Why It’s Urgent

  • Sometimes called “suicide headache” because of the intensity and frequency of attacks
  • Patients often need:
    • Acute abortive therapy
    • Preventive therapy
    • Bridge/transitional therapy

Treatment Principles

The Goal of Prevention

Prevention is not a cure. The goals are to:

  • Reduce attack frequency
  • Reduce intensity and duration
  • Improve response to acute medicines
  • Lower overall disease burden
  • Prevent progression to more frequent headaches
  • Improve quality of life and day-to-day functioning

When Preventive Therapy Is Used

Usually considered when:

  • Attacks are frequent
  • Attacks are very disabling
  • Acute medications are ineffective, poorly tolerated, or contraindicated
  • Headache frequency is high enough to risk chronification

Dr. Grosberg notes that many eligible patients still do not receive preventive therapy.

Preventive Treatments Discussed

Common Medication Classes

  • Beta blockers
    • Examples: propranolol, timolol
    • Used mainly for migraine
    • Caution with asthma, low blood pressure, low heart rate, exercise intolerance
  • Antidepressants
    • Examples: amitriptyline, nortriptyline
    • Often used at doses much lower than depression dosing
    • Can help especially when insomnia is part of the picture
  • Anti-seizure medications
    • Examples: topiramate, valproic acid
    • Useful for migraine prevention
    • Side effects and reproductive considerations are important
  • Calcium channel blockers
    • Especially useful in cluster headache
    • Verapamil can require high doses and EKG monitoring
  • Botox
    • FDA-approved for chronic migraine
    • Useful when patients have 15+ headache days/month

CGRP-Targeted Therapies

One of the biggest advances in headache medicine.

Monoclonal Antibodies

  • Monthly self-injections or quarterly infusion
  • Target CGRP or its receptor
  • Have significantly changed care for many patients
  • Help many, but not all; response varies by person and by drug

Oral CGRP Antagonists (“Gepants”)

  • Shorter-acting small molecules
  • Used for prevention and/or acute treatment depending on the drug
  • Examples discussed:
    • Atogepant – preventive
    • Rimegepant – preventive and acute
    • Ubrogepant – acute

Botox Details

  • Works through a non-cosmetic mechanism
  • Injected according to the PREEMPT protocol
  • Targets forehead, sides of head, back of head, neck, and shoulders
  • Insurance often requires trying other therapies first

Acute / Rescue Treatments

Non-Specific Options

  • Acetaminophen
  • NSAIDs
  • Generally avoid routine reliance on:
    • Opioids
    • Barbiturate-containing combinations
  • Why avoid them:
    • They raise the risk of medication-overuse headache
    • They can worsen chronification

Migraine-Specific Acute Treatments

Triptans

  • First modern migraine-specific acute drugs
  • Examples include sumatriptan and others in the class
  • Best used early, before allodynia and central sensitization fully develop
  • Formulations matter:
    • Oral
    • Nasal
    • Dissolving
    • Injectable

Ergot Derivatives

  • Older migraine-specific options
  • Still used in some cases

Choosing the Right Acute Therapy

Depends on:

  • Attack speed
  • Nausea / gastric stasis
  • Need for rapid onset
  • Prior response
  • Risk of recurrence
  • Tolerability

Neuromodulation and Non-Drug Options

  • External neuromodulation devices may help some patients
  • Examples include:
    • Trigeminal nerve stimulation
    • Vagus nerve stimulation
    • Remote electrical neuromodulation armband devices
  • Can be used for acute treatment and/or prevention depending on device
  • Particularly attractive for:
    • Patients who prefer fewer medications
    • Patients who are pregnant or trying to conceive
    • Patients who want adjunctive options

Cannabis / THC

  • A substantial portion of headache patients report use
  • Evidence remains difficult to interpret because:
    • Products vary widely
    • Dosing/formulation are inconsistent
    • Benefits may be indirect via sleep or anxiety rather than headache itself
  • More rigorous studies are still needed

Red Flags: When to Suspect a Secondary Headache

Seek more caution if there is:

  • New headache pattern
  • Headache change in a known sufferer
  • Fever or rash
  • Neck stiffness / pain with flexion
  • Unintended weight loss
  • New headache during pregnancy
  • Immune suppression
  • Neurologic symptoms:
    • Weakness
    • Numbness
    • Speech problems
    • Double vision
    • Vision loss
    • Balance issues
  • New headache after age 50
  • Thunderclap onset: peak intensity in seconds to a minute
  • Headache triggered by cough, exertion, sex, or positional change
  • Signs suggestive of CSF leak
    • Worse when upright
    • Better lying down
    • “Second-half-of-the-day” headache
    • Interscapular pain

Practical Advice for Patients and Clinicians

  • Keep a headache diary
    • Timing
    • Severity
    • Sleep
    • Meals
    • Caffeine
    • Alcohol
    • Menstrual cycle
    • Triggers
    • Response to treatment
  • Bring the diary to the primary care doctor or specialist
  • Expect treatment to be individualized
  • Prevention often takes weeks to months to work
  • Migraine care is usually a marathon, not a sprint
  • Lifestyle changes and medication work best together

Notable Quotes / Insights

  • Migraine is an “invisible disease” that is often dismissed as “just a headache.”
  • A headache diary is often more valuable than any tracker because it captures the real-world timing and context of attacks.
  • “Not every trigger is the cause”—triggers matter most in biologically susceptible people.
  • Preventive treatment is about reducing burden, not curing the disease outright.

Bottom Line

This episode offers a deep clinical overview of headache disorders and a practical framework for understanding when headaches are likely to be migraine, tension-type headache, cluster headache, or something secondary and potentially serious. The key message is that headache medicine is highly individualized: accurate diagnosis, a detailed history, and consistent tracking often matter more than scans or labs, and modern therapies—especially CGRP-targeted treatments—have made major improvements possible for many patients.
