1/5. Resolution of MRI abnormalities of the oculomotor nerve in childhood ophthalmoplegic migraine.ophthalmoplegic migraine is an uncommon disorder, usually starting in older childhood. Its physiopathology remains obscure and diagnosis is reliant on clinical grounds and exclusion of other disorders. We report four cases of childhood ophthalmoplegic migraine, one of them starting in infancy. association with other types of migraine is common. Two of the three patients studied by magnetic resonance imaging (MRI) showed enhancement and enlargement of the cisternal portion of the oculomotor nerve, which spontaneously resolved after 2 and 4 years, respectively. Persistence of clinical recurrences was associated with long-lasting presence of the MRI finding, and possibly with mild sequelae. These radiological abnormalities suggest a common physiopathological mechanism with other inflammatory diseases, except for a benign evolution which, added to its specific anatomic site, seems to be the only neuroradiological marker, besides normality, in ophthalmoplegic migraine. The very long potential duration of MRI changes and the scarcity of clinical episodes make feasible its incident discovery once the migraine attack has become a remote memory.- - - - - - - - - - ranking = 1keywords = attack (Clic here for more details about this article) |
2/5. Migraine associated with panic attacks.Migraine headache and panic disorder are two conditions that have a number of underlying physiological and psychological abnormalities in common. The temporal relationship between the occurrence of migraine headache and panic attacks could be different, however. According to our observations, some migraine subjects develop panic attacks with the typical symptoms (palpitation, dyspnea, anxiety/fear, shiver, sweating, polyuria) on the "peak" of their attacks. This variant of migraine without aura was conditionally defined as "panic migraine". Here we describe two patients suffering from migraine without aura in whom migraine was associated with the typical panic attack. It is suggested that a pronounced autonomic dysregulation along with marked psychological abnormalities could be responsible for the constellation of migraine and panic symptoms during one episode. Taking into account the previously obtained results, it is concluded that compared to "pure" migraine, "migraine associated with panic attacks" is characterized by a severe course, marked autonomic and emotional disturbances during pain-free intervals, seriously impaired quality of life, and requires a specific therapeutic approach.- - - - - - - - - - ranking = 346.51504142273keywords = panic attack, panic, attack (Clic here for more details about this article) |
3/5. Coexistence of cervicogenic headache and migraine without aura (?).It is well known that migraine with aura may coexist with various unilateral headaches, like cluster headache and chronic paroxysmal hemicrania. It may also coexist with cervicogenic headache. The diagnosis of migraine without aura ("common migraine") poses greater problems than the diagnosis of migraine with aura. Cervicogenic headache diagnosis also poses problems when these two headaches coexist, since they have symptoms in common. Therefore, the scientific demonstration of coexistence of migraine without aura and cervicogenic headache is bound to be a difficult task. In the present study, migraine without aura and cervicogenic headache seemed to coexist in 4 patients (3 F and 1 M, mean age 50). Attacks with migraine characteristics fulfilled the IHS and IASP migraine criteria. Out of a maximum of 13 migraine characteristics based on the IHS/IASP migraine criteria, such as unilaterality, aggravation on minor physical activity, etc., none of the patients presented less than 11, as opposed to a mean of < or = 4 of these criteria in the cervicogenic type attacks. A similar system, based on criteria such as: reduction of range of motion in the neck, mechanical precipitation of attacks, etc., was also developed for cervicogenic headache. The mean number of cervicogenic headache criteria was 4.3 (out of a total of 5) in the "cervicogenic part of the picture", as opposed to 1.5 (1.8 if laterality is considered, see text) in the "migraine part of the picture". Drug regimens and anaesthetic blocks also showed different results in the two different headaches in the same patient. All in all, this study seems to support a coexistence of the two headache types.- - - - - - - - - - ranking = 2keywords = attack (Clic here for more details about this article) |
4/5. Reversible, strokelike migraine attacks in patients with previous radiation therapy.We report 2 adults with a past history of radiation therapy to the head for malignancy (one with primary B-cell lymphoma confined to the skull and the other with multiple hemangioendotheliomas) who developed episodes consistent with migraine with and without aura. In addition to more typical migraine attacks and beginning many years after their radiation therapy, both patients have experienced infrequent, stereotyped, prolonged, reversible neurologic deficits associated with headache, occasional seizures, and striking, transient, cortical gadolinium enhancement of the posterior cerebral gyri on MRI. Interictal MRI brain scans show stable abnormalities consistent with the patients' previous radiation therapy. The neurologic deficits often progressed over a few days, sometimes lasted weeks, and completely resolved. Electroencephalograms did not show epileptiform activity. Thorough investigation showed no residual or recurrent tumor and no recognized cause for the patients' attacks. We postulate a causal relationship between the patients' remote radiation therapy and their prolonged, strokelike migraine attacks. radiation-induced vascular changes could provoke the episodes, with or without an underlying migraine diathesis. Recognition of this syndrome can help avoid invasive testing.- - - - - - - - - - ranking = 7keywords = attack (Clic here for more details about this article) |
5/5. Resolution of cluster headache after closure of an anterior communicating artery aneurysm: the role of pericarotid sympathetic fibres.We report the case of a patient suffering from migraine without aura since childhood who, at the age of 58 years, developed cluster headache (CH) attacks. This second type of headache was related to an aneurysm of the anterior communicating artery (ACoA) whose bursting caused subarachnoid haemorrhage. The aneurysm's clipping made the cluster headache subside and there was no recurrence for almost four years. However, nine months after haemorrhage, the patient experienced new migraine without aura attacks. As a pathogenetic interpretation of this secondary cluster headache, we discuss the possible role of pericarotid sympathetic nerves in cluster headache attacks. We suggest that the surgical dissection of the pericarotid sympathetic fibres could prevent the onset of the cluster headache attacks by cutting part of the circuit underlying it.- - - - - - - - - - ranking = 4keywords = attack (Clic here for more details about this article) |
