The comorbidity of headache and psychiatric symptoms is a well-recognized clinical phenomenon, but there are only limited data regarding the temporal relationship between headache and symptoms of anxiety and depression as well as behavioral problems in adolescents. This study investigates the relationship of anxiety and depressive symptoms and behavioral problems at baseline with recurrent headache at follow-up four years later. ⋯ Results from the present study showed that symptoms of anxiety and depression in early adolescence were associated with recurrent headache four years later. Recognizing anxiety and depressive symptoms should be considered part of the clinical assessment in young headache patients, as early identification of these associated factors may lead to improved headache management.

A lack of habituation of different evoked potential modalities in migraine patients in-between attacks has been suggested. ⋯ Our findings can be primarily deemed to demonstrate that patients and healthy controls show significantly lower amplitudes while performing the calculation task. Without performing the calculation task we could not show the expected lack of habituation in migraineurs. Yet, while performing the calculation task our results partly suggest that hypothesis.

Primary headache disorders are among the commonest disorders, affecting people in all countries. India appears to be no exception, although reliable epidemiological data on headache in this highly populous country are not available. Such information is needed for health-policy purposes. Our aim was to estimate the prevalence of each of the headache disorders of public-health importance, and examine their sociodemographic associations, in urban and rural populations of Karnataka, south India. ⋯ There is a very high 1 year prevalence of migraine in south India (the mean global prevalence is estimated at 14.7%). Explanations probably lie in cultural, lifestyle and/or environmental factors, although the observed associations with female gender and rural dwelling are usual. Levels of TTH, pMOH and other headache on ≥15 days/month are similar to global averages, while the very strong association of pMOH with female gender requires explanation. Until another study is conducted in the north of the country, these are the best data available for health policy in a population of over 1.2 billion people.

Patients suffering from migraine with aura can have either pure visual auras or complex auras with sensory disturbances and dysphasia, or both. Few studies have searched for possible pathophysiological differences between these two subgroups of patients. ⋯ Our findings suggest that in migraine with aura patients different aura phenotypes may be underpinned by different pathophysiological mechanisms. Pre-activation cortical excitability could be higher in patients with complex neurological auras than in those having pure visual auras or in healthy volunteers.

Headache disorders are common worldwide, causing pain and disability. India appears to have a very high prevalence of migraine, and of other headache disorders in line with global averages. Our objective was to estimate the burdens attributable to these disorders in order to inform health policy. ⋯ In Karnataka State, southern India, prevalent headache disorders, especially migraine, give rise to commensurately heavy burdens. Limited access to health care fails to alleviate these. Structured headache services, with their basis in primary care, are the most efficient, effective, affordable and equitable solution. They could be implemented within the health-care infrastructure of India and are likely to be cost-saving. This solution requires political will, itself dependent on awareness.
