1/747. Transient paralytic attacks of obscure nature: the question of non-convulsive seizure paralysis.

    Eleven patients with transient paralytic attacks of obscure nature are described. paralysis could involve face or leg alone, face and hand, or face, arm and leg. The duration varied from two minutes to one day. Four patients had brain tumors, six probably had brain infarcts, and one a degenerative process. The differential diagnosis included TIAs, migraine accompaniments, and seizures. In the absence of good evidence for the first two, the cases are discussed from the standpoint of possibly representing nonconvulsive seizure paralysis (ictal paralysis, inhibitory seizure paralysis or somatic inhibitory seizure). Because of the difficulty in defining seizures as well as TIAs and migraine in their atypical variations, a firm conclusion concerning the mechanisms of the spells was not attained. Two cases of the hypertensive amaurosis-seizure syndrome have been added as further examples of ictal deficits.

2/747. Serial electroencephalographic findings in patients with MELAS.

    To clarify the electroencephalographic characteristics of mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS), the medical records and electroencephalograms of six patients with MELAS and two of their relatives with MELA (mitochondrial myopathy, encephalopathy, and lactic acidosis, without strokelike episodes) were retrospectively reviewed. All have a point mutation in the mitochondrial dna at nucleotide position 3243. The electroencephalograms (n = 79) were divided into four groups according to the time relation to the strokelike episode: (1) before the first strokelike episode, (2) within 5 days after the strokelike episode (acute stage), (3) between 6 days and 1 month after the strokelike episode (subacute stage), and (4) more than 1 month after the strokelike episode (chronic stage). In the acute stage, 10 of the 11 electroencephalograms (9 strokelike episodes in four patients) revealed focal high-voltage delta waves with polyspikes (FHDPS), which were recognized as ictal electroencephalogram. Ictal events during FHDPS included focal clonic or myoclonic seizure and migrainous headache. In the subacute and chronic stages, focal spikes or sharp waves and 14- and 6-Hz positive bursts were frequently recorded. The authors' results suggest that FHDPSs present a reliable and accurate indicator of a strokelike episode in patients with MELAS.

3/747. Limb-threatening lower extremity ischemia successfully treated with intra-arterial infusion--case reports.

    The authors present two patients with acute arterial vasospasm of the lower extremities causing marked ischemia. One patient had a history of Raynaud's disease, the second had been taking Cafergot for migraine headaches. Both patients's were given a test dose of intra-arterial tolazoline (50 mg). The patient with Raynaud's disease demonstrated marked improvement diffusely and was successfully treated with overnight infusion of papaverine. The second patient, taking Cafergot, demonstrated no angiographic response to tolazoline. It was speculated that the arteries of this patient were thrombosed. The patient was successfully treated with urokinase and remained free of pain at the 15-month follow-up.

4/747. Lamotrigine in the prophylactic treatment of migraine aura--a pilot study.

    The aim of this study was to evaluate the efficacy of lamotrigine, a glutamate antagonist blocking voltage-sensitive sodium channels, in the prophylaxis of migraine aura symptoms. Glutamate is one of the main neurotransmitters involved in the development of cortical spreading depression. The study was conducted as an open longitudinal trial over 7 months, with a treatment phase of 4 months and a post-treatment period of 3 months. Thirteen patients suffering from migraine with aura and 2 patients with aura but without migraine were enrolled and treated with lamotrigine. The dose was gradually increased in steps of 25 mg up to 100 mg per day, depending on the patient's aura symptoms. Aura symptoms were reduced from baseline (an average of 1.3 aura episodes per month) to month 4 (0.1, p < 0.001). High statistical significance was also observed with regard to aura duration (23 min at baseline vs 4 min at 4 months, p < 0.001). In all 15 cases, increases in aura frequency (on average sevenfold, p < 0.001) and aura duration (minutes; on average more than threefold, p < 0.001) were evident following cessation of treatment. A number of mild to moderate adverse events without any medical consequences occurred. The study outcome suggests that lamotrigine is effective in preventing migraine aura symptoms and in influencing migraine headache frequency.

5/747. Medicolegal issues: headache.

    This article addresses headache-related topics in which medicolegal issues have occurred or in which they are likely to occur. Where possible, an actual case has been presented. Most sections of this article are divided into three parts: principle of care, case history, and discussion and recommendations. When appropriate, American Academy of neurology guidelines have been noted.

6/747. Familial hemiplegic migraine with cerebellar ataxia and paroxysmal psychosis.

    Familial hemiplegic migraine is a rare autosomal dominant disorder associated with stereotypic neurologic aura phenomena including hemiparesis. So far two chromosomal loci have been identified. Families linked to the chromosome 19 locus display missense mutations within the CACNL1A4 gene. Here we report on a family with familial hemiplegic migraine and cerebellar ataxia with recurrent episodes of acute paranoid psychosis with anxiety and visual hallucinations associated with migraine attacks. Based on the clinical and haplotype evidence indicating linkage to chromosome 19 in this family, we hypothesize that a dysfunction of the mutated calcium channel may be involved not only in the development of hemiplegic migraine but also in the acute psychotic episodes observed in these patients.

7/747. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.

    The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.

8/747. Prolonged migraine aura without headache arrested by sumatriptan. A case report with further considerations.

    The case of a 42-year-old woman with prolonged migraine visual aura without headache, whose long-lasting episodes of visual aura were successfully controlled by oral sumatriptan, is reported. Effectiveness of sumatriptan was unequivocal, since, after taking sumatriptan, duration of aura would drop from 1.5 h to approximately 20 min. This case suggests that sumatriptan may cross the blood-brain barrier and block spreading depression.

9/747. Migraine complicated by brachial plexopathy as displayed by MRI and MRA: aberrant subclavian artery and cervical ribs.

    This article describes migraine without aura since childhood in a patient with bilateral cervical ribs. In addition to usual migraine triggers, symptoms were triggered by neck extension and by arm abduction and external rotation; paresthesias and pain preceded migraine triggered by arm and neck movement. Suspected thoracic outlet syndrome was confirmed by high-resolution bilateral magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brachial plexus. An unsuspected aberrant right subclavian artery was compressed within the scalene triangle. The aberrant subclavian artery splayed apart the recurrent laryngeal and vagus nerves, displaced the esophagus anteriorly, and effaced the right stellate ganglia and the C8-T1 nerve roots. Scarring and fibrosis of the left scalene triangle resulted in acute angulation of the neurovascular bundle and diminished blood flow in the subclavian artery and vein. A branch of the left sympathetic ganglia was displaced as it joined the C8-T1 nerve roots. Left scalenectomy and rib resection confirmed the MRI and MRA findings; the scalene triangle contents were decompressed, and migraine symptoms subsequently resolved.

10/747. Coincidence of familial hemiplegic migraine and hemicrania continua? A case report.

    A case is presented of a 39-year-old woman with a history of simultaneous Familial hemiplegic migraine (FHM) and hemicrania continua (HC). The family history of the patient revealed different types of migraine and cyclic syndromes in childhood in four generations. The possible links between FHM and HC are discussed. The pedigree gives further evidence that cyclic syndromes in childhood belong to the spectrum of migraine.
