The objectives of this paper are to evaluate the efficacy and tolerability of topiramate, given at the dose of 100 mg/day, in the prophylactic treatment of migraine. The hypothesis that migraine is the result of a condition of neuronal hyperexcitability and the quest for drugs that are able to limit the number of crises justifies the attempt to utilise the(More)
Primary headaches are closely related to sleep. Modifications in the patterns of arousal during sleep have been reported in migraine, especially in the nights preceding a headache attack. We aimed at evaluating the pattern of arousal from sleep in a group of patients affected by sleep-related migraine. We enrolled 10 consecutive patients, three males and(More)
The habituation to sensory stimuli of different modalities is reduced in migraine patients. However, the habituation to pain has never been evaluated. Our aim was to assess the nociceptive pathway function and the habituation to experimental pain in patients with migraine. Scalp potentials were evoked by CO(2) laser stimulation (laser evoked potentials,(More)
We report the clinical, pathological, and genetic findings of a case of MELAS syndrome. This was a man who died for metabolic failure at the age of 27 years. His familiar history was positive for hypoacusia and stroke. He was of short stature and presented mild mental retardation. Since the age of 21 he suffered from recurrent brain-ischemic lesions mainly(More)
In lambs, acute and chronic communicating hydrocephalus has been created by merely increasing the amplitude of the intraventricular cerebrospinal fluid (CSF) pulsations, leaving the mean CSF pressure unchanged. The pathologic changes occurring in this type of hydrocephalus do not differ qualitatively from those observed in obstructive hydrocephalus. Beside(More)
The brains of 3 adult subjects suffering from normotensive hydrocephalus have been examined pathologically. The diagnosis of normotensive hydrocephalus was based on clinical symptoms, pneumoencephalography and isotope cisternography, in 1 case integrated with the results of the constant-infusion manometric test. Part of the neuropathological findings were(More)
OBJECTIVE We aimed to evaluate and compare the auditory performance of neurofibromatosis type 2 (NF2) patients with bilateral total deafness fitted with cochlear or auditory brainstem implants. PATIENTS AND METHODS A retrospective case review was performed. Nine patients suffering from NF2 who underwent hearing rehabilitation by means of cochlear (4(More)
In this work we have developed and characterized primary cultures of neonatal rat trigeminal ganglia neurones; calcitonin-gene-related-peptide (CGRP) released from cells was taken as a marker of neuronal function. A significant and consistent increase in CGRP secretion was elicited by non-specific (56 mm KCl or veratridine) or specific (capsaicin)(More)
One case of CJD with severe involvement of the white matter is discussed. The patient was admitted after a 3-month clinical course with rapidly increasing mental deterioration, coma vigil-like state, myoclonic twitching of the limbs and of the facial muscles. The EEG showed the typical features of CJD. The first CT scan, performed 3 months after onset,(More)
Brainstem auditory and visual potentials were recorded from 6 patients with chronic idiopathic polyradiculoneuropathy. Evoked potentials were either completely absent or their latency was prolonged suggesting slow conduction in visual or auditory pathways. The results of our study provide further evidence suggesting subclinical involvement of cranial nerves(More)
