Altered processing of sensory stimuli in patients with migraine.

2014

Migraine is a cyclic disorder, in which functional and morphological brain changes fluctuate over time, culminating periodically in an attack. In the migrainous brain, temporal processing of external stimuli and sequential recruitment of neuronal networks are often dysfunctional. These changes reflect complex CNS dysfunction patterns. Assessment of multimodal evoked potentials and nociceptive reflex responses can reveal altered patterns of the brain's electrophysiological activity, thereby aiding our understanding of the pathophysiology of migraine. In this Review, we summarize the most important findings on temporal processing of evoked and reflex responses in migraine. Considering these d…

Brain excitability in migraine: Hyperexcitability or inhibited inhibition?

2007

While migraine has been considered for a long time a disease of the head vascular structures, it has been more and more evident that the involvement of the cerebral cortex has a primary role in the cascade of events which trigger the migraine attacks. Neurophysiological studies gave an important contribution to our knowledge of the mechanisms underlying the migraine disease

Survey on treatments for primary headaches in 13 specialized juvenile Headache Centers: The first multicenter Italian study

2017

Abstract Aim The purpose of this retrospective multicenter study was to evaluate the use and the self-perceived efficacy and tolerability of pharmacological and non-pharmacological treatments in children and adolescents with primary headaches. Methods Study of a cohort of children and adolescents diagnosed with primary headache, consecutively referred to 13 juvenile Italian Headache Centers. An ad hoc questionnaire was used for clinical data collection. Results Among 706 patients with primary headaches included in the study, 637 cases with a single type of headache (migraine 76% – with and without aura in 10% and 67% respectively; tension-type headache 24%) were selected (mean age at clinic…

Different neuronal contribution to N20 somatosensory evoked potential and to CO2 laser evoked potentials: an intracerebral recording study

2004

Abstract Objective : To investigate the possible contribution of the primary somatosensory area (SI) to pain sensation. Methods : Depth recordings of CO 2 laser evoked potentials (LEPs) and somatosensory evoked potentials (SEPs) were performed in an epileptic patient with a stereotactically implanted electrode (Talairach coordinates y =−23, z =40) that passed about 10 mm below the hand representation in her left SI area, as assessed by the source of the N20 SEP component. Results : The intracerebral electrode was able to record the N20 SEP component after non-painful electrical stimulation of her right median nerve. The N20 potential showed a phase reversal in the bipolar montage (at about …

Relapse risk factors in anti-N-methyl-D-aspartate receptor encephalitis

2019

Aim: To identify factors that may predict and affect the risk of relapse in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. Method: This was a retrospective study of an Italian cohort of patients with paediatric (≤18y) onset anti-NMDAR encephalitis. Results: Of the 62 children included (39 females; median age at onset 9y 10mo, range 1y 2mo–18y; onset between 2005 and 2018), 21 per cent relapsed (median two total events per relapsing patient, range 2–4). Time to first relapse was median 31.5 months (range 7–89mo). Severity at first relapse was lower than onset (median modified Rankin Scale [mRS] 3, range 2–4, vs median mRS 5, range 3–5; admission to intensive care unit: 0/10 vs 3/10…
