INTRODUCTION
There are an estimated 28 million migraine sufferers in the United States but less than half are appropriately diagnosed and even less adequately treated. From a public health standpoint, primary care is the only medical specialty in a position to handle the large and growing headache population. Therefore, it is imperative that an effective standard of care be instituted for the primary care clinician.
The Role of Primary Care Clinicians
4. Prevent the evolution of inadequately controlled headache to chronic daily headache through appropriate patient management.
Migraine is a heterogeneous condition both in terms of symptomatology and impact on sufferers. Most attacks of migraine produce at least temporary disability despite efforts of self-management. Poorly controlled migraine can become extremely disabling causing frequent disruption of family, social, and work related activities. In fact, a quarter of employed migraineurs indicates that their career development has been negatively affected by migraine.
Few physicians screen for migraine from their patient populations and there are no public health initiatives to encourage screening despite the prevalence, impact, and treatability of the disorder. In fact, it is generally left to the patient to decide when migraine is a significant medical problem worth bringing to the attention of the medical provider. As a consequence, migraine is often mentioned in passing during evaluations of other medical conditions. By the time an individual seeks treatment for a disabling headache, he or she has already failed self-management and is experiencing significant disability.
Barriers to Recognizing Migraine in Primary Care
The sum of these obstacles to care may in part account for the high degree of dissatisfaction with medical care voiced by the headache population.
RECOGNITION OF MIGRAINE
Migraine Recognition in Primary Care
The advisory committee consensus is that migraine can be recognized in clinical practice by exploring the following four questions:
Headaches that produce significant disability should be considered migraine until proven otherwise. Allowing a patient to explain the impact of headaches helps define disability, establishes rapport, and directs therapeutic interventions. For example, headaches that restrict important activities such as work or home responsibilities suggest a need for aggressive therapy whereas headaches with less impact may be adequately treated with OTCs. In this way, the physician provides the tools for managing the spectrum of headache activity and paves the way for patient-centered care. In the long run, the physician manages the patient rather than just headaches.
An affirmative answer demonstrates the need for a more in-depth evaluation while a negative response reassures the physician and patient that serious underlying disease is unlikely.
This information alerts the physician to chronic headache disorders and migraine transformation. Frequent headaches raise the issue of adding a migraine preventive to the patients treatment regimen. The question will also differentiate migraine from cluster headache.
This identifies individuals who overuse acute treatment medications, which may lead to an analgesic rebound headache pattern. It is essential to query patients about prescription and OTC medication usage. Overuse of any analgesic, prescription or OTC, may promote more frequent headaches. Self-management efforts can be assessed and therapy can be modified to meet all of the patients needs.
Comfort Signs
Adding questions about prodrome, aura, postdrome, family history, and menstrual association can further reassure the patient and physician. Scheduling follow-up visits allows the physician to identify the rare secondary cause of headaches, assess treatment response, screen for co-morbidities, such as depression or irritable bowel syndrome, and monitor use of medication.
ACUTE TREATMENT STRATEGY FOR MIGRAINE
Migraine is a recurrent self-limited neurological event characterized by headache and other systemic symptoms. The creation of an acute treatment strategy for migraine involves five steps:
PHARMACOLOGICAL INTERVENTION AND MIGRAINE
The primary reason a patient sees a physician for migraine is to secure effective pharmacological intervention for the treatment of acute migraine. Fortunately, there is a wide range of drugs available for treatment of acute migraine. Therefore, it is advisable that a provider targets medications to specific phases of migraine pathophysiology.
Clinical Pathology of Acute Migraine
The cascade of neurological changes that constitutes an acute attack of migraine generally occurs in a predictable fashion. Appreciating the clinical evolution of the migrainous process is the key to a rational pharmacological approach. Clinically, an acute attack of migraine can be divided into five phases: prodrome, aura, headache, resolution, and postdrome. Therapeutically, these can be grouped into pre-headache (prodrome and aura), headache, and post-headache (postdrome). Conceptualizing these three phases helps the selection of the most effective pharmacological approach.
Pre-headache
The pre-headache phase may be characterized by non-specific symptoms, such as fatigue, mood disruption, muscle pain, or food cravings or focal neurological symptoms of an aura. Many patients are not aware of these symptoms until theyve been educated about prodromes. For example, cervical muscle tension may be part of prodrome yet is often misinterpreted as being a tension headache. Food craving may result in chocolate consumption and be interpreted as a migraine trigger. However, for many patients, pre-headache is an individualized pattern that carries the indisputable message that a migraine is imminent. Prodrome precedes the onset of migraine in 50% or more of migraine attacks. Presumably, these symptoms result from neurochemical disruption of CNS homeostasis. Many of these symptoms continue during the headache phase of migraine, but are generally overshadowed by the drama of head pain.
Several theories suggest that the pre-headache phase results from an imbalance of neuromodulating transmitters such as serotonin and/or dopamine. In simplified terms, dopamine represents an excitatory side of neuromodulation while serotonin represents the inhibitory side of the equation. Prodromal symptoms relate to excess dopamine stimulation decreases in serotonin activity.
The therapeutic implications of understanding prodromes are enormous. If interventions are instituted during this phase, the headache itself may be averted. Many patients have discovered this through experience and report that if they take medications at the "right point in time," they can avert an impending migraine. Common prodromes include changes in energy level, alterations of sensory processing or cognition, food craving, and tender muscles in the head and neck.
Headache
The headache phase of migraine is characterized by headache which typically begins as mild pain and escalates to moderate or severe throbbing pain. Associated with the headache are numerous symptoms reflecting disruption of the central nervous system. These include sensory disruption, nausea and/or vomiting, mood disruption, cognitive disruption, and muscle tenderness in the head and neck, and autonomic disruptions. This symptom complex is frequently severe enough to produce significant disability and approximately one thirds of attacks result in confinement to bed. Generally, an attack of migraine lasts between 4 and 72 hours but may be shorter especially in children and adolescents.
Numerous factors need to be considered when developing a treatment strategy for the headache phase of migraine. The time from onset until peak intensity of pain or the presence of significant nausea generally determines the need for rapid acting interventions. Several options exist, such as using a parenteral formulation to circumvent the GI system, timing pharmacological intervention to precede the onset of significant GI symptoms, or adding an antiemetic prior to or with medication. In addition, important personal or work activities may affect treatment need. These are best managed when patients have multiple treatment options available to them.
Several clinical studies have demonstrated that triptans have significantly better efficacy taken when pain is mild as compared to moderate to severe. It would appear from this data and clinical experience that the more intense the headache phase has become prior to onset of therapy, the less likely a patient is to experience an abortive response to triptans.
Post-headache
The post-headache phase is characterized by lingering associated symptoms without headache. Most commonly this includes GI symptoms with a queasy, sick stomach and food intolerance, decreased concentration and occasional cognitive difficulties, sore muscles and general an overall sense of fatigue. This can last up to 48 hours.
PHASE-SPECIFIC ACUTE THERAPY (see Figure 2)
Patients need to understand the evolution of their migraine attacks over time. By specifying certain medications for the various phases of migraine, patients can prevent or avoid much of the disability associated with migraine. In the long run, self-management integrated with effective pharmacology is the most effective form of therapy
Acute Treatment
Acute treatment is defined as an intervention aimed at aborting the migrainous process that is imminent or once it has started.
Goals of Acute Therapy
Effective therapy is attainable in a majority of patients even though these goals may not be attained in all patients or for every migraine attack.

BEHAVIORAL AND PHYSICAL TREATMENTS
Behavioral therapy should be part of managing all headache patients. It can come in small installment with words of encouragement or formalized consultations. Whenever possible, behavioral therapy should be proactive and not instituted after "everything" has failed.
A migraineur is born with a more sensitive nervous system. For confidence in being able to manage migraine, a person needs to learn to recognize cues that indicate their system is at risk and to know what to do to reestablish equilibrium. Inherent in this concept is the migraine threshold.
The central nervous system constantly adjusts to changes in the external and internal environment. If demands placed on the nervous system exceed its ability to make these adjustments a migraine occurs. The migraine threshold is this theoretical line between physiological adjustment and the initiation of migraine. The migraine threshold is largely determined by genetic factors. However three other factors appear to lower the threshold for migraine. These include overuse of acute treatment medication (analgesic rebound headache), frequent uncontrolled attacks of migraine (kindling), and psychological assaults.
The factors that put the nervous system at risk for an attack of migraine are often stereotypic and predictable. Modification of these factors or learning to respond differently to them can reduce the frequency and impact of migraine. A month-long diary of headaches is the most effective tool for identifying these precipitating events and risk factors (see Table 1). An individual can counter these risk factors with activities that protect the nervous system from exceeding the migraine threshold (see Table 2).
Biofeedback
Numerous studies support the use of biofeedback to prevent migraine. The majority of patients in primary care can teach themselves to relax and warm their finger temperature by listening to soothing music for 10 minutes once or twice a day. This process is especially effective for children and migraineurs who are considering pregnancy.
Biofeedback is the process of bringing involuntary physiological functions under voluntary control. Finger temperature, for instance, is a reflection of the bodys level of vigilance. The average finger temperature is 85 degrees F. As the stress response builds in the body, the finger temperature decreases. When the finger temperature is chronically low (below 80 degrees F), the body is in the survival mode, usually signifying that the individual has lost the ability to relax and re-create. Biofeedback trains the nervous system to shutout stimulation. Through biofeedback, the individual steps back from daily concerns, and focuses on returning the body to homeostasis, through calming, relaxing music and/or visualization. As this occurs, the finger temperature rises. The goal is 96 degrees F.
Cognitive Approaches
Coping Skills: Due to the sensitivity of the migraineurs nervous system, there is an alertness to the feelings of others. Often, migraine sufferers feel responsible for anothers distress or apathy. Once they understand their sensitivity, they realize that they have a choice and they can decide to shut out others demands without feeling guilty. The coping skills that headache sufferers generally find useful include cognitive restructuring, assertiveness training, and identifying goals.
Cognitive Restructuring: Negative self-talk is an automatic private conversation that goes on inside a persons mind in response to an occurrence in the environment. Often these negative evaluations of oneself are unconscious. Under guidance from a psychologist or counselor, the individual identifies negative self-talk and changes the disparaging remarks to positive messages. Through this process, the individual becomes in touch with both mind and body and as a result, has more control over health.
Assertiveness Training: Certain individuals believe that saying "no" or standing up for themselves will lead to rejection, abandonment, or an aggressive confrontation. Differentiating assertiveness from aggressiveness is a step-by-step process:
Identifying Goals: Once assertive behavior is learned, the person needs to establish goals rather than rely on others to dictate behavior. Goals need to be written down and divided into a time frame, such as within 1 week, 1 month, 6 months, 1 year, and 5 years.
Manual Methods
Acupuncture/Acupressure: Using fine metal needles or mechanical pressure, the acupuncturist manipulates energy called Chi to help the individual return to a balanced state.
Manipulative Procedures: A skilled practitioner moves joints or muscles in an effort to relieve tension and promote normal joint mechanics. When muscle tension precedes or accompanies the headache or when there has been an injury to the neck or head or spine, manipulative therapies may help alleviate the circuitry of pain.
Massage: A massage relaxes the body and releases stress buildup in muscle tissue.
Vitamins, Minerals, Herbs
Riboflavin (200-400 mg per day)
Vitamin B Complex (1 tablet per day).
Magnesium (500-750 mg per day)
Feverfew/Valerian Root (one capsule 3-4 times per day for one month. If effective, the dosage may be slowly decreased if desired.)
Aspirin: one per day
SYSTEM MANAGEMENT
The treatment need of the migraine population varies widely from occasional office visits to prolonged hospitalizations. Most migraine sufferers can be managed within the scope of office-based primary care. However at times, resources beyond those typically found in primary care must be utilized. This section explores situations and resources available for managing of these patients.

Worrisome Features:
Consultation/referral
There are two major reasons for referral of headache patients. Neurological referral may be indicated in certain cases for diagnostic evaluation. This may be necessitated when the headache pattern is inconsistent with migraine or there is a need for reassurance by either patient or provider. Examples of appropriate consultation might be patients with atypical or prolonged aura, complicated migraine (basilar, hemiplegic, ophthalmoplegic) or if the diagnosis is uncertain.
Some complex patients have concomitant medical issues that may benefit from referral to other specialists such as internal medicine, nephrology, psychiatry or psychology.
When assistance in headache management is needed it is best to seek out a headache specialist. Headache specialists often have diverse backgrounds such as neurology, anesthesia, internal medicine, and family practice. Interest in headache management is actually more important in selecting a headache specialist than is their board certification. Sharing management of complicated cases with a headache specialist can often improve outcomes.
In-Patient Management
In-patient care is infrequently required for headache patients. Exceptions include patients with unrelenting migraine (status migrainosus) and patients who need monitoring during drug detoxification. One approach that had been helpful for many patients with status migrainosus is known as the Raskin protocol. Successful in-patient programs commonly employ an interdisciplinary approach, including psychology, biofeedback, education and social services.
Working with 3rd Party Payers
In this era of managed care it not uncommon for third parties to intervene in the management of headache. Often this intervention is intended to reduce the cost of treatment to the health plan with dollar savings as the main objective rather than improving patient outcomes. The primary method of achieving the goal of reducing pharmacy cost is to mandate a step care approach of treatment despite mounting evidence that stratified care is more effective than step care.
In order to achieve the best outcomes for patients it is important for clinicians to:
