ABOUT CHRONIC MIGRAINE

Chronic Migraine is a prevalent and well-defined condition, yet many patients remain undiagnosed.1-7

ICHD-3* Criteria

Headache on ≥ 15 days per month for more
than 3 months

≥ 5 prior migraine attacks (with or without aura)

On ≥ 8 days per month for > 3 months,
headache fulfills criteria for migraine
headache (with or without aura)

Not better accounted for by another
ICHD-3 diagnosis

With or without medication overuse

PRACTICAL CLINICAL CRITERIA

Headache on ≥ 15 days per month

≥ 8 days are migraine days;
headaches last ≥ 4 hours per day

With or without medication overuse

3.3 million: Adults in the United States with Chronic Migraine

75%: Patients who do not receive a Chronic Migraine diagnosis despite meeting the criteria (n = 512)

56%: Patients who do not have their condition managed by a Headache Specialist (N = 609)

3.9: Number of preventive treatments the average Chronic Migraine patient has already tried (n = 493)

*The International Classification of Headache Disorders, 3rd edition.
Based on 2010 data estimating a 1.4% incidence of Chronic Migraine and a 234,504,070 US 2010 adult population (.014 x 234,504,070 ≈ 3.3 million).

CHRONIFICATION OF MIGRANE

Migraine is a disorder that may progress along a continuum from low-frequency episodic migraine to Chronic
Migraine. As patients chronify, they experience pervasive physiological changes that distinguish Chronic Migraine
from other headache subtypes.8

Watch the "Chronification of Migraine" video to learn how persistent migraine can cause increased sensitization of
the central nerve centers as well as structural abnormalities of the brain, underscoring the importance of Chronic
Migraine identification and diagnosis.8

DIAGNOSIS

Many patients struggle with debilitating headache for years without understanding the true nature of their condition.
A Chronic Migraine diagnosis can help patients better understand their condition and become more open to
treatment options.

Watch headache expert Dr. Lawrence Newman share strategies you can utilize to diagnose Chronic Migraine for your patients in need, including:

  • Focusing on headache days, rather than just migraine attacks, and asking about headache-free days

  • Considering days when a patient took an over-the-counter medication or simply dealt with the pain

  • Evaluating patients for medication-overuse headache

DOCUMENTATION

There are several factors to consider when diagnosing Chronic Migraine, including headache frequency, symptoms, duration, and day-to-day impact. Download these tools so patients can accurately document their headache burden to help a doctor with a Chronic Migraine diagnosis.

PATIENT EDUCATION

As patients learn more about their condition, they may begin to feel less frustrated and become willing to discuss different treatment options. Provide these resources to your patients to help educate them about Chronic Migraine and available treatments.

TREATMENT OPTIONS

A complete Chronic Migraine management plan may include both acute
and preventive treatments.9

Acute treatment*

Acute medications are an important treatment option for Chronic
Migraine patients and should be optimized to help avoid medication
overuse. Withdrawal from acute medications and preventive treatment
may be appropriate in cases of medication overuse.9,10

Preventive treatment*

According to expert opinion, people with Chronic Migraine could
benefit from a preventive treatment,11 and many patients have tried
several oral options already.

Learn more about a preventive treatment option

*Help your patients understand their treatment options. Acute treatments are taken as needed when a
  migraine/headache is starting or has already begun, and may stop or reduce pain. Preventive (prophylactic)
  treatments are taken on a schedule and may prevent migraine/headache days before they start.
