Working up the Headache Patient History Most important of all! Exam General and neurological Lab Basics if warranted; ESR if over 60 years Neuroimaging Not routinely warranted Consider if: first or worse, change in pattern Abnormal exam, under age 5 and over age 50, history of trauma Neurology. 1994;44:1353-1354. CT head vs. CT sinus vs. MRI

The Symptom-based Approach to Diagnosing Migraine At least 5 attacks 4 to 72 hours Pain (2 of 4) Unilateral location Pulsating quality Moderate or severe intensity Aggravation by or causing avoidance of routine physical activity (e.g. walking or climbing stairs) In addition (1 of 2) Nausea and/or vomiting Photo and phonophobia No evidence of organic disease International Headache Society. Cephalalgia. 2004;24 (Suppl. 1):24-27.

Chronic Daily Headaches Rare disorder Only 5 percent of the U.S. population suffer from severe headaches on a daily basis 3 percent meet criteria for chronic tension-type headaches Account for majority of consultations seen in headache subspecialty practices

Chronic Daily Headache Classification Difficult to classify under current IHS guidelines Alternative classification separated chronic daily headache into primary and secondary types Primary chronic daily headache can be subclassified by average daily headache duration New system includes entities not recognized by IHS

Chronic Migraine Prior history of episodic migraine starting during adolescence or twenties Female predominance As headache frequency increases, typical migrainous features become less frequent and severe Many migraine features persist Superimposed full-blown migraines

Chronic Migraines In the general population 30-50 percent of patients overuse medications Headaches increase in frequency with increasing medication use Headache improvement correlated with discontinuing analgesics Significant long-term improvement seen following detoxification

Transformed Migraines Eighty percent are depressed; improves as medication overuse discontinued Transformed Migraine not recognized by IHS Silberstein et al recently proposed criteria Prior IHS migraine criteria Period of escalating headache frequency with decreasing migraine

Diagnosis of Medication Overuse Headache Diagnosis and treatment take time1 Offending medications must be stopped and prophylactic medications started Diagnosis is confirmed in retrospect Patients typically overuse multiple medications simultaneously2 Mean tablets/day = 5.2 Most commonly overused medications Drugs. Butalbital combinations acetaminophen 1. Smith and Stoneman. 2004;64:2503-2514. 2. Bigal et(48%), al. Cephalalgia. 2004;24:483-490. (46%), opioids (33%), ASA (32%), triptans (18%)

Recognition of Medication Headache Overuse HAs are refractory and frequent (near daily) Patient frequently uses excessive quantities of analgesics; tolerance may develop HAs may vary in severity, location, and type HAs are easily triggered by slight physical or mental effort Weakness, nausea, anxiety, irritability, and cognitive problems often accompany HA HA spontaneously improves when Diener and Katsarava.

Time Is Critical in Harvard Research Suggests: From Preventing Migraine A Sequence of Events Leads to Central Becoming Full-blown Sensitization Meningeal blood vessel Thalamus Peripheral neuron (trigeminal ganglion) Pain pathways Central neuron (dorsal horn) Within minutes of a migraine being triggered, the peripheral neurons that innervate meningeal blood vessels become sensitized Burstein R et al. Ann Neurol. 2000;47:614-624. Burstein R et al. Brain. 2000;123:1703-1709. If migraine is left untreated, those peripheral pain neurons activate and sensitize central neurons, leading to central sensitization Central sensitization signifies full-blown migraine, when central neurons are continually firing and the attack becomes more difficult to treat

Tips on Triptans Don t do a grab bag Try one drug for 3 to 4 migraines with early intervention and at the right dose Talk about nausea and use appropriate formulation Dose selection Insurance limitations Don t give up if one doesn t work They aren t diagnostic tools They are equally safe They are a single class of drug

Guidelines to migraine treatment Two days of treatment per week ( of anything) Watch for escalation of dose and frequency Avoid addictive substances in patients at risk Watch for catch phrases and doses

Pharmacologic Treatment of Migraine Preventive vs. Acute Medication Preventive medication given daily to decrease migraine: Frequency Severity Duration Acute care medication given during an attack to: Decrease severity and duration Treat associated migraine symptoms (nausea, photophobia, sonophobia and vomiting)

Methods (cont d) The self-administered survey included questions on: Headache symptoms/features (to classify cases) Headache-related impairment (none, some, severe, or bed rest required) Migraine Disability Assessment (MIDAS) Headache frequency Headache frequency data were collected 2 ways: A. About how often do your severe headaches occur? # in a week OR # in a month OR # in a year B. On how many days in the last 3 months did you have a headache? (From MIDAS) Prevention # of daysneed was Prevention need was estimated estimated using using both both approaches, approaches, data data for for the the more more conservative conservative approach approach B B are are presented presented here. here. Lipton RB. Headache. 2005;65:792. Abstract F38.

Prevention Need The decision to use preventive treatment should be based on doctor-patient collaboration as well as: Headache frequency Headache-related impairment In this study self-reported past 3-month headache frequency data were obtained (via MIDAS) and standardized to an average month Expert consensus Lipton RB. Headache. 2005;65:792. Abstract F38. was used to classify individuals

Preventive Rx Need Among Migraine Cases (Past 3-Month Frequency Based on MIDAS) Monthly Migraine Days How are you usually affected by severe headaches?

Pharmacologic Treatment of Migraine Preventive vs. Acute Medication Preventive medication given daily to decrease migraine: Frequency Severity Duration Acute care medication given during an attack to: Decrease severity and duration Treat associated migraine symptoms (nausea, photophobia, sonophobia and vomiting)

Consider Migraine Preventive Medication When The Patient Has: 1. Recurring migraine that the patient feels significantly interferes with his or her daily routine 2. Two or more attacks per month that produce disability lasting three or more days per month 3. Overuse of acute medications (>2 week) 4. Acute medications are ineffective, contraindicated, or not well tolerated 5. An uncommon migraine condition: Hemiplegic Migraine Migraine with Prolonged Aura 6. Patient preference Migrainous Infarction Basilar Migraine Silberstein SD et al. Headache. 2003;43:171; Snow et al. Annals of Internal Medicine. 2002;137:846.

How to Choose Therapy Evidence-based Sleep disorders Related to comorbid condition depression anxiety /panic epilepsy

Using Preventive Start Medications with low dose and increase slowly Allow time for an adequate trial (2 to 6 months) Avoid drug overuse and interfering drugs Evaluate therapy Use a headache calendar Taper (and stop?) if headaches well controlled No established guideline on this clinical practice generally runs from 6 to 18 months of well-controlled migraines Discuss pregnancy issues before initiating therapy
