“…In our study, five patients had preictal headaches with migrainous qualities, albeit only four with sufficient duration (>4 h) to be classified as migraine. None experienced migraine auras, in contrast to other studies [19,20].…”

“…Many authors have tried to explore this association, but with rather diverse findings. The prevalence of migraine in individuals with epilepsy varies from 2% to 24% [4,6,7,11,12,[16][17][18][19][20]. This large variation is probably due to differences in classifications of both disorders, as well as in the selection of patient populations and diagnostic instruments.…”

Headaches add to the burden of epilepsy

et al. 2007

The objective was to investigate and classify headaches in 109 consecutive adult patients with epilepsy. A semi-structured interview was performed in those who confirmed such symptoms (65%). Interictal headaches were present in 52%; 20% had interictal migraine. Postictal headache was reported in 44%. Migraine characteristics were present in 42% of these, and most of them (74%) also suffered from interictal migraine. Six percent had preictal headache. In partial epilepsy, there was an association between headache lateralisation and interictal EEG abnormalities (p=0.02). We conclude that headache, including migraine, is very common in patients with epilepsy. Unilateral headache may represent a lateralising sign in focal epilepsy. Seizures often trigger postictal headaches with migraine features, which often are associated with interictal migraine. Migrainous headaches sometimes proceed into epileptic seizures. The comorbidity of migraine and epilepsy should receive ample clinical attention, as it may influence antiepileptic drug choice, and the headache may need specific treatment.

“…Seizures as a trigger in patients genetically prone to migraine should be taken into account like other potent triggers (e.g., nitroglycerin) to a susceptible brain. The data concerning migraine aura induced epilepsy (migralepsy) is highly variable and was reported in 1.7-16 % of patients suffering from epilepsy and migraine with aura [59,105]. Comorbidity of migraine and epilepsy leads to negative effect on the prognosis of epilepsy with lower probability of being seizure free after a 10-year followup and a higher incidence of intractable epilepsy [104].…”

Migraine-associated risks and comorbidity

2008

This review reports important co-morbid conditions of migraine and resulting consequences for the choice of acute and preventive treatments of migraine. Comorbidity in this context means the occurrence of two diseases in an individual beyond chance. The basis of comorbidity can be genetic and/or based on common environmental factors. In some cases, the temporal relationship is unclear and one disease can cause another disease. In order to prove a real comorbidity, large-scale and well-performed epidemiological studies are required.

“…A relationship between migraine and epilepsy has long been postulated, with recent clinical and epidemiological studies having demonstrated that both are highly co-morbid [83][84][85]. Although migraine prevalence in patients with epilepsy is high (14% to 20%), only a few (1.7% to 3%) experience seizures in close temporal proximity to migraine [84,85].…”

SynopsisEpidemiological studies have shown that migraine headaches are a common finding in the general population, often associated with a high degree of disability. Additionally, migraine has a reported co-morbidity with other medical conditions, most notably with chronic pains such as temporomandibular disorders (TMD). The pathophysiological mechanisms involved with migraine are suggestive of an increased and prolonged hyperexcitability to stimuli, especially within the trigeminal distribution. Since migraine is mediated via branches of the trigeminal nerve it has the potential to mimic other types of pains, such as toothache or sinusitis. Therefore, it is recommended that oral and maxillofacial surgeons be familiar with the diagnostic criteria for migraine headaches in order to identify and appropriately treat such individuals who present to their clinics. KeywordsMigraine Headache; Diagnosis; Epidemiology; Pathophysiology; Oral Surgery; Pain IntroductionNeurovascular pains, otherwise known as headaches, are a group of pain disorders that are felt as cephalalgias, or pains in the head. Likely they are a heterogeneous group of disorders that share a common anatomic region of presentation, the head, but have somewhat separate pathophysiological mechanisms. For the most part, neurovascular pains are currently viewed Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

For this reason these pain disorders were historically referred to as 'vascular pains' [1], but further research has identified both peripheral and central aspects of the nervous system are playing crucial roles in the initiation and perpetuation of these pains [2,3]. This brought about a change in nomenclature regarding headache, which are now referred to as 'neurovascular pains disorders', stressing the neuropathic aspect of migraine. (Table 1) Research has continued to more closely associate headache disorders with neuropathic mechanisms, which is starting to result in a shift in how headaches are viewed -from both clinical and research perspectives. In the midst of this paradigm shift this article seeks to provide an overview of the epidemiologic data and pathophysiologic mechanisms of one type of neurovascular pain, that being migraine headaches. The reason for focusing on migraine headache is because they are known to be common in the population [4,5] and have been reported to have the most disability associated with them [6,7], making migraine headache the prototypic neurovascular pain disorder.
