Clinical Trial
Patients with chronic tension-type headache demonstrate increased mechano-sensitivity of the supra-orbital nerve.
This study aimed to establish whether increased sensitivity to mechanical stimuli is present in neural tissues in chronic tension-type headache (CTTH). ⋯ These findings reveal that mechanical hypersensitivity is not limited to muscles but also occurs in cranial nerves, and that the level of sensitization, either due to peripheral or central processes, is related to the severity of the primary headache.

Head pain arises within the trigeminal nociceptive system. Current theories propose that the trigeminal system is intimately involved in the pathogenesis of migraine. Short-latency responses can be recorded in sternocleidomastoid muscles after stimulation of the trigeminal nerve (trigemino-cervical reflex). This brainstem reflex could be a suitable method to evaluate the trigeminal system in migraine and CH. ⋯ Our results further support the relevance of brainstem mechanisms in the pathogenesis of migraine rather than of CH. These data, taken together with that from experimental head pain and functional imaging studies, demonstrate that primary headache syndromes may be distinguished on a functional basis by areas of activation specific to the clinical syndrome.

Migraine is common, with an estimated lifetime prevalence of 7-17%. Population-based studies have reported an association between various psychiatric conditions and migraine. This is a population-based study exploring the association between migraine and psychiatric disorders in a large cohort and assessing various health-related outcomes. ⋯ Migraine is associated with major depressive disorder, bipolar disorder, panic disorder, and social phobia. Migraine in association with various mental health disorders results in poorer health-related outcomes compared with migraine or a psychiatric condition alone. Understanding the psychiatric correlates of migraine is important in order to adequately manage this patient population and to guide public health policies regarding health services utilization and health-care costs.

The aim of this retrospective study was to determine if neck pain, select headache characteristics, and migraine-related coping response predicted disability in migraineurs referred to a tertiary headache clinic. ⋯ These data suggest the need for prospective research exploring the causal mechanisms by which neck pain and coping response influence disability and underscores the importance of multidisciplinary approaches to headache management.
