Exercise for prophylaxis of migraine

Aerobic Exercise and Plasma Beta Endorphin Levels in Patients with Migrainous Headache Without Aura

This study aims to evaluate the effects of plasma beta endorphin level and exercise on migrainous headache. Forty patients with migrainous headache without aura (MWOA), firstly exercised on a treadmill and afterwards were asked to continue an aerobic home exercise program for six weeks. On evaluation, basal plasma beta endorphin level was negatively correlated with total duration of attacks in the last month period ( P = 0.01). Exercise was found to have beneficial effects on all migraine parameters ( P < 0.0001) and to increase beta endorphin levels after the treadmill practice ( P < 0.0001) and after the home exercise program except four patients not regularly attended to the program ( P < 0.0001). Any of the changes in headache parameters was not correlated with the change in beta endorphin level. However, pre-exercise beta endorphin level was found to be negatively correlated with the changes in the number of attacks ( P < 0.05) and total duration of attacks ( P = 0.01) and also with the change in beta endorphin level due to exercise ( P < 0.0001). As a result, this study emphasizes the beneficial effect of exercise on migrainous headache, especially in patients with lower basal beta endorphin level.

Synergistic Effects of Six Chronic Disease Pairs on Decreased Physical Activity: The SMILE Cohort Study

Little is known about whether and how two chronic diseases interact with each other in modifying the risk of physical inactivity. The aim of the present study is to identify chronic disease pairs that are associated with compliance or noncompliance with the Dutch PA guideline recommendation and to study whether specific chronic disease pairs indicate an extra effect on top of the effects of the diseases individually. Cross-sectional data from 3,386 participants of cohort study SMILE were used and logistic regression analysis was performed to study the joint effect of the two diseases of each chronic disease pair for compliance with the Dutch PA guideline. For six chronic disease pairs, patients suffering from both diseases belonging to these disease pairs in question show a higher probability of noncompliance to the Dutch PA guideline, compared to what one would expect based on the effects of each of the two diseases alone. These six chronic disease pairs were chronic respiratory disease and severe back problems; migraine and inflammatory joint disease; chronic respiratory disease and severe kidney disease; chronic respiratory disease and inflammatory joint disease; inflammatory joint disease and rheumatoid arthritis; and rheumatoid arthritis and osteoarthritis of the knees, hips, and hands.

The role of diet and lifestyle in adolescents with headache: a review

Several dietary habits and lifestyles can be associated with different headache types or with their progression to chronic forms. Different population-based studies have tried to investigate this relationship with poor or contradictory results. We shortly reported the current knowledges available in literature in this regard, paying particular attention to the role that certain factors play in modifying frequency and intensity of headache in adults and in adolescents. Future studies are necessary to clarify the real weight which the different factors have in natural history and in clinic evolution of headache, especially in adolescence, but the already known data suggest an important modulating action. If they will be confirmed, these results will be likely to influence clinical practice as well to address educational programs in preadolescents and adolescents.

Exercise as migraine prophylaxis: a randomized study using relaxation and topiramate as controls

AIM

Scientific evidence regarding exercise in migraine prophylaxis is required. Therefore this study aimed to evaluate the effects of exercise in migraine prevention.

METHODS

In a randomized, controlled trial of adults with migraine, exercising for 40 minutes three times a week was compared to relaxation according to a recorded programme or daily topiramate use, which was slowly increased to the individual's highest tolerable dose (maximum 200 mg/day). The treatment period lasted for 3 months, and migraine status, quality of life, level of physical activity, and oxygen uptake were evaluated. The primary efficacy variable was the mean reduction of the frequency of migraine attacks during the final month of treatment compared with the baseline.

RESULTS

Ninety-one patients were randomized and included in the intention-to-treat analysis. The primary efficacy variable showed a mean reduction of 0.93 (95% confidence interval (CI) 0.31-1.54) attacks in the exercise group, 0.83 (95% CI 0.22-1.45) attacks in the relaxation group, and 0.97 (95% CI 0.36-1.58) attacks in the topiramate group. No significant difference was observed between the groups (p = 0.95).

CONCLUSION

Exercise may be an option for the prophylactic treatment of migraine in patients who do not benefit from or do not want to take daily medication.

Physical practice is associated with less functional disability in medical students with migraine

The aim of this study was to investigate possible association between migraine and physical practice among 480 medical students who were submitted to a questionnaire about headaches and physical practices. Migraine diagnosis was assessed by ID-Migraine and functional disability was evaluated with MIDAS. The type (aerobic or strength training), the weekly frequency and the intensity of physical practice and body mass index (BMI) were assessed. There was a reduction in functional disability of migraine in students reporting physical practice (no physical practice - MIDAS=8.81±1.40, physical practice - MIDAS=15.49±1.78; P=0.03). Frequency, intensity, and type of physical practices were not associated with functional impact of migraine. BMI did not correlate with migraine impact (normal weight - MIDAS=12.34±1.33, overweight or obese - MIDAS=17.45±3.86; P=0.33). These results were confirmed by multivariate analysis. Our data suggest that physical practice is inversely related with functional disability of migraine in university students regardless of BMI.

Association between lifestyle factors and headache

Modification of lifestyle habits is a key preventive strategy for many diseases. The role of lifestyle for the onset of headache in general and for specific headache types, such as migraine and tension-type headache (TTH), has been discussed for many years. Most results, however, were inconsistent and data on the association between lifestyle factors and probable headache forms are completely lacking. We evaluated the cross-sectional association between different lifestyle factors and headache subtypes using data from three different German cohorts. Information was assessed by standardized face-to-face interviews. Lifestyle factors included alcohol consumption, smoking status, physical activity and body mass index. According to the 2004 diagnostic criteria, we distinguished the following headache types: migraine, TTH and their probable forms. Regional variations of lifestyle factors were observed. In the age- and gender-adjusted logistic regression models, none of the lifestyle factors was statistically significant associated with migraine, TTH, and their probable headache forms. In addition, we found no association between headache subtypes and the health index representing the sum of individual lifestyle factors. The lifestyle factors such as alcohol consumption, smoking, physical activity and overweight seem to be unrelated to migraine and TTH prevalence. For a judgement on their role in the onset of new or first attacks of migraine or TTH (incident cases), prospective cohort studies are required.

Physical activity and headache: results from the Nord-Trøndelag Health Study (HUNT)

The aim of this study was to evaluate, using a prospective and a cross-sectional design, the relationship between level of physical activity and migraine and non-migraine headache. In the prospective part, 22,397 participants, not likely to have headache, answered questions about physical activity at baseline (1984-1986) and responded to a headache questionnaire at follow-up. In the cross-sectional part (1995-1997), 46,648 participants answered questions about headache and physical activity. Physically inactive individuals at baseline were more likely than active individuals to have non-migraine headache 11 years later (odds ratio 1.14, 95% confidence interval 1.02, 1.28). In the cross-sectional analyses, low physical activity was associated with higher prevalence of migraine and non-migraine headache. In both headache groups, there was a strong linear trend (P < 0.001) of higher prevalence of 'low physical activity' with increasing headache frequency. The result may indicate that physical inactivity among headache-free individuals is a risk factor for non-migraine headache and that individuals with headache are less physically active than those without headache.

[Exercise in migraine treatment. Review and discussion of clinical trials and implications for further trials]

Regular exercise is recommended in general treatment guidelines for migraine. However, scientific evidence in support of this recommendation is weak. The majority of available trials on this topic do not meet modern requirements for randomized clinical trials. Often the diagnosis of migraine is not certain, the duration of treatment is too short, and the intervention is not clearly defined; furthermore, the control of treatment is insufficient. The study results are controversial regarding the efficiency of sports intervention in migraine. Regular exercises may have specific effects on the course of disease in migraine through increase of fitness or relaxing effects. It remains unclear whether exercise alone is efficient in migraine treatment or only as part of a more multidisciplinary program. Theoretical considerations, the available limited studies, and clinical experience suggest that exercise may have an effect on migraine, but the present knowledge does not fulfill the needs of evidence-based medicine. Future studies should adhere to the rules for randomized clinical trials in pharmacological migraine prophylaxis.

Prevalência e características da cefaléia em uma população de praticantes regulares de exercícios físicos

MOTIVO: O impacto causado pela cefaléia pode impedir a aderência a um programa regular de atividade física. OBJETIVO: Avaliar a prevalência e as características da cefaléia em uma população de praticantes de exercícios físicos. MÉTODO: Cem alunos de uma academia foram avaliados. Todos eram alunos regulares por pelo menos 12 meses e praticavam exercícios aeróbicos pelo menos 3 vezes por semana. Um questionário sobre a prevalência e características da cefaléia foi aplicado a todos aqueles que apresentaram nos últimos 12 meses. O questionário de avaliação de impacto MIDAS também foi aplicado. RESULTADOS: 57 homens e 43 mulheres foram incluídos. Oitenta apresentaram cefaléia no período avaliado. Em 63% a dor era pulsátil. Em 73% da amostra a freqüência de crises situava-se em menos de 1 vez a cada 10 dias. O escore do questionário MIDAS foi inferior a 5 em 83% desses pacientes. CONCLUSÃO: Embora não avaliados por médico e baseado em recall, os dados sugerem alta prevalência de cefaléia com critérios de migrânea. É incerto se a prática regular de exercícios físicos reduz a freqüência de crises ou se os sofredores de cefaléia com baixa freqüência de crises são os que fazem atividade física regular.

A clinical review of the adaptive role of vasopressin in migraine

Vasopressin is a naturally available neuropeptide that subserves important vasomotor, antinociceptive, behavior control, fluid and electrolyte balance, platelet aggregation and blood coagulation functions. This review focuses on the clinical phenomena of migraine that are likely to influence vasopressin bioavailability or efficacy as well as the modulating influence of vasopressin itself. As part of a complex homeostatic adjustment to stress and pain, the intricacies of vasopressin metabolism may have particular relevance to the pathophysiology of migraine.
