Workplace productivity. A review of the impact of migraine and its treatment.

Migraine is a common disorder characterised by recurrent episodes of disability. Despite the high prevalence of migraine, data have been lacking on its impact in a working population. The advent of new therapies has stimulated interest in this area, and evidence is now available that documents the substantial impact of migraine on workplace productivity and the likelihood of untreated migraine leading to unemployment or underemployment for the patient. This paper reviews current findings of both observational and interventional studies about the impact of migraine on productivity and employment. When considered in the light of migraine demographics, the high prevalence of migraine, and its low consultation and treatment rates, this evidence indicates that improved screening and treatment for this common condition could have a substantial impact on worker productivity and on patient well-being.

Evaluation of migraineurs' preferences for naratriptan over conventional first-line agents.

OBJECTIVE: To assess patient satisfaction with and preference for naratriptan hydrochloride therapy over previous "nontriptan" therapy for migraines. DESIGN AND SETTING: Open-label study conducted at 15 primary care clinics. PATIENTS: One hundred forty-three adults meeting International Headache Society diagnostic criteria for migraine who were not using triptans as first-line therapy for migraines were enrolled; 115 completed the study. INTERVENTION AND OUTCOME ASSESSMENTS: At baseline, satisfaction with current migraine therapy was assessed. Patients were provided with naratriptan hydrochloride, 2.5 mg, to treat 3 migraines and diaries to record headache symptoms and response to treatment. After treating 3 migraines, satisfaction with naratriptan therapy and preference for either previous or naratriptan therapy were assessed. RESULTS: Eighty-nine (62%) of 143 patients had previous exposure to triptans, with lack of prescribing (55%) as the primary reason for not continuing their use as first-line therapy. Medications used for first-line therapy included simple analgesics (59%), combination products (46%), and narcotics (13%). After treating 3 migraines with naratriptan, satisfaction with migraine therapy increased from 47% to 75%. Sixty-three percent of patients preferred naratriptan therapy over their previous nontriptan therapy, 27% preferred their previous therapy, and 10% had no preference. The main reasons for preference for naratriptan therapy were "relieves pain effectively" (86%) and "restores ability to function/perform task" (81%). CONCLUSION: Naratriptan for first-line migraine therapy was preferred by most patients over previous nontriptan therapy.

Prevention of migraine during prodrome with naratriptan.

OBJECTIVE: To determine the role of naratriptan in preventing migraine headache when administered during prodrome. PROCEDURES: Baseline phase: patients recorded prodrome symptoms and time of onset, time when patient knew that headache was inevitable, time of onset and severity of headache. Treatment phase: patients given naratriptan 2.5 mg to take at the time they knew headache was inevitable. Patients recorded prodrome symptoms and time of onset, time they knew headache was inevitable, time naratriptan administered, time of onset and severity of any headache. Patients treated three prodromes separated by at least 48 h. FINDINGS: Twenty patients completed both phases. During baseline phase, 59 prodromes were reported and all were followed by headache. Severity of headache: 5% mild, 51% moderate, 44% severe. During treatment phase, 63 prodromes were reported. Of these, 38/63 (60%) were not followed by headache. Among headaches that occurred, the majority occurred within 2 h of naratriptan administration, suggesting that naratriptan is more effective in preventing headache if taken early in prodrome. Severity of 25 headaches: 44% mild, 24% moderate, 32% severe. CONCLUSIONS: Naratriptan 2.5 mg appears to prevent migraine headache when given early in prodrome. If headache occurs, severity appears to be reduced.

A pilot study to measure cognitive efficiency during migraine.

BACKGROUND AND OBJECTIVES: The measurement of cognitive efficiency during migraine has produced conflicting results primarily due to the types of tests used. The objectives of this pilot study were two-fold: to measure cognitive efficiency during migraine, compared to a migraine-free period, and to evaluate the effects of therapy with a 5-HT1 agonist (sumatriptan injection, 6 mg) on the cognitive efficiency of migraineurs during a migraine. METHOD: The Headache Care Center-Automated Neuropsychological Assessment Metrics was administered to 10 migraineurs, three times without a migraine, once during a migraine, and three times after administration of sumatriptan injection (6 mg). RESULTS: The results demonstrated a significant drop in cognitive efficiency during migraine and recovery 15 minutes after therapeutic injection. CONCLUSIONS: This pilot study is the first to document a significant drop in cognitive functioning during migraine and recovery after administration of a migraine-specific medication.

Analgesic rebound headache in clinical practice: data from a physician survey.

BACKGROUND: Frequent, excessive use of over-the-counter or prescription analgesics may lead to analgesic rebound headache. Little is known about the magnitude of the health problem posed by analgesic rebound headache, its epidemiology, the characteristics of analgesic rebound headache sufferers, or about physicians' approaches to treatment. METHODS: Four hundred seventy-three practitioners, who had previously expressed an interest in the treatment of headache, were mailed a questionnaire designed to capture information about the frequency and management of analgesic rebound headache and about the characteristics of analgesic rebound headache sufferers. RESULTS: Completed questionnaires were returned by 174 practitioners (37%) from 40 states, the District of Columbia, and Puerto Rico. More than 40% of respondents indicated that analgesic rebound headache was present in at least 20% of their patients. On average, the physicians reported that 73% of patients with analgesic rebound headache were women. Analgesic rebound headache was most likely to occur in patients aged 31 to 40 years. No one analgesic was consistently identified as causative, although acetaminophen, butalbital + aspirin + caffeine, and aspirin were commonly used by patients. Eighty percent of respondents indicated that depression was commonly observed in analgesic rebound headache sufferers; 77% indicated that physical conditions (especially gastrointestinal symptoms) were commonly observed. A variety of therapeutic strategies, including pharmacotherapy, were used in the management of analgesic rebound headache. CONCLUSION: Analgesic rebound headache was recognized as a distinct entity and a substantive component in more than 40% of the practices of 174 surveyed practitioners. General practitioners, who see a wide variety of patient types with a spectrum of complaints, need to be able to diagnose analgesic rebound headache by taking a good history.

2000 Wolfe Award. Sumatriptan for the range of headaches in migraine sufferers: results of the Spectrum Study.

BACKGROUND: Migraineurs experience a spectrum of headaches: migraine, migrainous, and episodic tension-type as defined by the International Headache Society (IHS). OBJECTIVE: To evaluate the effectiveness of sumatriptan, 50-mg tablets, in treating the spectrum of headaches in IHS-diagnosed migraineurs. DESIGN/METHODS: Migraineurs with severe disability (Headache Impact Questionnaire score 250 or greater) were enrolled in a randomized, double-blind, placebo-controlled, crossover study. Patients treated up to 10 headaches with sumatriptan, 50 mg, or placebo (4:1). Headache features, recorded prior to treatment, were used to classify each headache using IHS criteria. Headache response (moderate or severe pain reduced to mild or no pain) and pain-free response were recorded at 2 and 4 hours postdose (primary endpoint). Because patients treated multiple attacks, statistical methods controlling for within-subject correlation were used. RESULTS: Two hundred forty-nine migraineurs treated 1576 moderate or severe headaches: migraine (n = 1110), migrainous (n = 103), and tension-type (n = 363). Sumatriptan was superior to placebo for headache response 4 hours postdose (primary endpoint) across all headache types (migraine, 66% versus 48%; P<.001; migrainous, 71% versus 39%; P<.01; tension-type, 78% versus 50%, P<.001). Sumatriptan was also superior to placebo for pain-free response 4 hours postdose for migraine (41% versus 24%, P<.001) and tension-type headaches (56% versus 36%, P =.001). Sumatriptan provided superior pain-free response 2 hours postdose for migraine (18% versus 7%, P<.0001) and tension-type headache (28% versus 14%, P =.0005) compared with placebo. CONCLUSION: Sumatriptan, 50-mg tablets, are effective for the full spectrum of headaches experienced by patients with disabling migraine due to a sumatriptan-responsive mechanism.
