Cephalalgia : an international journal of headache

The objective of this article is to review the prospect of treating migraine with sphenopalatine ganglion (SPG) neurostimulation. ⋯ We propose two possible mechanisms of action: 1) interrupting the post-ganglionic parasympathetic outflow to inhibit the pain and cephalic autonomic symptoms, and 2) modulating the sensory processing in the trigeminal nucleus caudalis. To further explore SPG stimulation in migraineurs as regards therapeutic potential and mode of action, randomized clinical trials are warranted.

Headache has not been established as a risk factor for dementia. The aim of this study was to determine whether any headache was associated with subsequent development of vascular dementia (VaD), Alzheimer's disease (AD) or other types of dementia. ⋯ In this prospective population-based cohort study, any headache was a risk factor for development of VaD.

Rhinitis is a comorbidity of migraine, but its relationship to migraine headache frequency and headache-related disability is unknown. ⋯ The frequency and disability of migraine are higher in persons with rhinitis, particularly those with mixed rhinitis. These results, however, should be considered preliminary until confirmed in future studies because of the modest questionnaire response rate in this study.

To present data from a population-based epidemiological study on menstrual migraine. ⋯ More than one of every five female migraineurs aged 30-34 years have migraine in ≥50% of menstruations. The majority has menstrual migraine without aura and one of eight women had migraine with aura in relation to their menstruation. Our results indicate that the ICHD III beta appendix criteria of menstrual migraine are not exhaustive.
