The aim of this study was to explore the association between different types of headache (HA) and the clinical features of multiple sclerosis (MS). The relationship between HA and MS-specific therapies was also analysed. A total of 102 MS patients were recruited at the MS Centre of S. Andrea Hospital in Rome. According to International Headache Society criteria, the lifetime prevalence of primary HA was 61.8%. Migraine was observed more often in young relapsing-remitting MS patients, whilst tension-type HA was associated with older age, male gender and a secondary progressive course. Sixty-four patients had a history of ongoing or past interferon beta (IFNb) exposure. Of these, 17 subjects did not have a history of HA, while 24 complained of an increase in frequency of migraine attacks and 7 reported an IFNb-induced HA. Investigating and treating HA in MS patients starting IFNb therapy may improve MS-specific medication compliance.

Our findings support the use of zonisamide as an alternative therapy for migraine prevention in patients with good response, but poor tolerance to topiramate.

Migraine is a common neurological disorder and epidemiological studies have documented its high social and economic impact. Unfortunately, preventive treatment is often insufficient to substantially reduce migraine frequency or it is not well tolerated. Antiepileptic drugs are increasingly used in migraine prevention. However, data on efficacy and tolerability of pregabalin in patients with migraine are still lacking. Our aim was to evaluate efficacy and tolerability of pregabalin in patients with migraine. We recruited 47 patients who started pregabalin at 75 mg/day, which was titrated to 300 mg/day as tolerated. A total of six patients (13%) reported one or more side effects during the intake of pregabalin; however, three of them discontinued pregabalin, because side effects were intolerable and persistent. Statistically significant reduction in migraine frequency compared to baseline (p \ 0.001) was evident after 1 and 3 months of treatment. A greater frequency reduction was observed in those patients who increased the dosage within the first month of therapy. Our data suggest that pregabalin may be well tolerated and may represent an alternative preventive treatment in migraneurs. Limitations of the present study were a small sample size and an uncontrolled, open-label design; further randomized case-control studies are warranted to confirm our findings.

Background. Endarterectomy (CEA) or stenting (CAS) of a stenotic carotid artery is currently undertaken to reduce stroke risk. In addition removal of the arterial narrowing has been hypothesized to improve cerebral hemodynamics and provide benefits in cognitive functions, by supposedly resolving a “hypoperfusion” condition. Methods. In this study we sought to test whether resolution of a carotid stenosis is followed by measurable changes in cognitive functions in 22 subjects with “asymptomatic” stenosis. Results. A main finding of the study was the statistically significant pre-post difference observed in the performance of phonological verbal fluency and Rey's 15-word immediate recall. Remarkably, there was a significant interaction between phonological verbal fluency performance and side of the carotid intervention, as the improvement in the verbal performance, a typical “lateralized” skill, was associated with resolution of the left carotid stenosis. Conclusion. The results reflect a substantial equivalence of the overall performance at the before- and after- CEA or CAS tests. In two domains, however, the postintervention performance resulted improved. The findings support the hypothesis that recanalization of a stenotic carotid could improve brain functions by resolving hypothetical “hypoperfusion” states, associated with the narrowing of the vessels.

Primary headaches are underdiagnosed and undertreated in patients with multiple sclerosis (MS). The aim of our study was to investigate the possibility of using the ID migraine™ (ID-M) questionnaire to make a first-line diagnosis of migraine in subjects affected by MS. We consecutively recruited 144 patients regularly attending the MS Centre of S. Andrea Hospital in Rome. Results from ID-M were matched with diagnoses of a blind neurologist. According to the ICHD-II criteria, 77 (53.5%) patients were diagnosed as suffering from migraine. ID-M showed high sensitivity (91%) and specificity (94%) in identifying patients with migraine. ID-M was also able to discriminate patients affected by headache following interferon beta therapy, having only the 10% out of these patients a positive ID-M. The use of the ID-M as a screening test is warranted not only in the epidemiological research, but also to ensure a better clinical management of patients with MS.
