Chronic migraine (CM) is a complex neurological disorder associated with substantial disability that affects approximately 2 % of general population. Onabotulinumtoxin A is employed for patients suffering from CM refractory to common therapeutic prophylaxis. Since May 2013, we have selected 22 patients referring to our headache centre with a history of CM which meets the diagnostic criteria of ICHD-3 beta (2013).

Outcome Predictors in First-Ever Ischemic Stroke Patients: A Population-Based Study.

Background. There is scant population-based information regarding predictors of stroke severity and long-term mortality for first-ever ischemic strokes. The aims of this study were to determine the characteristics of patients who initially presented with first-ever ischemic stroke and to identify predictors of severity and long-term mortality.

Parkinson's disease plasma biomarkers: an automated literature analysis followed by experimental validation.

Diagnosis of Parkinson's disease (PD) is currently assessed by the clinical evaluation of extrapyramidal signs. The identification of specific biomarkers would be advisable, however most studies stop at the discovery phase, with no biomarkers reaching clinical exploitation. To this purpose, we developed an automated literature analysis procedure to retrieve all the background knowledge available in public databases.

The cost of first-ever stroke in Valle d'Aosta, Italy: linking clinical registries and administrative data.

Background: Stroke is one of the most relevant reasons of death and disability worldwide. Many cost of illness studies have been performed to evaluate direct and indirect costs of ischaemic stroke, especially within the first year after the acute episode, using different methodologies.

Methods: We conducted a longitudinal, retrospective, bottom-up cost of illness study, to evaluate clinical and economic outcomes of a cohort of patients affected by a first cerebrovascular event, including subjects with ischaemic, haemorrhagic or transient episodes.

Epidemiology of stroke in northern Italy: the Cerebrovascular Aosta Registry, 2004-2008.

The progression of non-motor symptoms in Parkinson's disease and their contribution to motor disability and quality of life.

Non-motor symptoms are gaining relevance in Parkinson's disease (PD) management but little is known about their progression and contribution to deterioration of quality of life. We followed prospectively 707 PD patients (62 % males) for 2 years. We assessed non-motor symptoms referred to 12 different domains, each including 1-10 specific symptoms, as well as motor state (UPDRS), general cognition, and life quality.

Frontal assessment battery scores and non-motor symptoms in parkinsonian disorders.

Using data from the PRIAMO study, we investigated non-motor symptoms (NMS) versus frontal lobe dysfunction in patients with idiopathic Parkinson disease (PD); 808 patients with PD and 118 with atypical parkinsonisms (AP) were consecutively enrolled at 55 Centers in Italy. Twelve categories of NMS were investigated. Cognitive impairment was defined as a Mini-Mental Status Evaluation score ≤ 23.

Chiari and Syringomyelia Consortium: a model of multidisciplinary and sharing path for rare diseases.

Piemonte and Valle d'Aosta Interregional Network for Rare Diseases (RD) is a model of "diffuse" network; it involves all the health system specialists devoted to the diagnosis, the therapy and the follow-up of a RD. The Consortium is a multidisciplinary team operating throughout the Region composed of volunteer Physicians and Biologists that promotes periodical meetings to develop shared protocols. In 2008 the Specialist-Technical Committee for the Interregional RD Network approved the set up of the "Chiari and Syringomyelia Consortium" (CSC) with two specific objectives: to identify the shared diagnostic criteria and to develop the interdisciplinary diagnostic-therapeutic-assistance path (DTAP) to be used interregionally.

Psychosis associated to Parkinson's disease in the early stages: relevance of cognitive decline and depression.

Objective: To evaluate the prevalence of psychosis associated with Parkinson's disease (PSY-PD) in its early stages, its incidence over a 24 month follow-up period and the association with motor and non-motor clinical features.

Methods: PRIAMO is a 2 year longitudinal observational study that has enrolled patients with parkinsonism in 55 Italian centres. A cohort of 495 patients with early disease stage PD (baseline Hoehn and Yahr score ≤ 2, disease's duration (median) 3.

Blood C-reactive protein concentration with ABCD² is a better prognostic tool than ABCD² alone.

Background: Increased C-reactive protein (CRP) is a known predictor of vascular events in asymptomatic individuals and stroke patients. Only a few studies included transient ischaemic attack (TIA) patients. We assessed CRP levels in addition to traditional risk factors in a cohort of patients with TIA to examine the relationship of these parameters to the occurrence of ischaemic stroke.

Is there a prognostic role for C-reactive protein in ischemic stroke?

Objectives: We investigated the relationship between C-reactive protein (CRP)-values in the acute phase of stroke and the risk of further fatal and non-fatal ischemic events.

Materials And Methods: We analysed 462 consecutive incident ischemic strokes. Patients were divided into two subgroups on the basis of a CRP cut-off level of 9 mg/l.

Non-motor symptoms in atypical and secondary parkinsonism: the PRIAMO study.

The PRIAMO study is a cross-sectional longitudinal observational study aimed at describing epidemiology and evolution of non-motor symptoms (NMS) in patients with different forms of parkinsonism recruited in 55 Italian centres and evaluated over 24 months. In this paper, we are reporting prevalence and clinical characteristics of NMS in patients with atypical and secondary parkinsonism. Out of 1307 consecutive patients with a diagnosis of parkinsonism, 83 patients had vascular parkinsonism (VP), 34 had multiple system atrophy (MSA), 30 had progressive supranuclear palsy (PSP), 14 had dementia with Lewy bodies (DLB) and 11 had corticobasal degeneration (CBD).

The PRIAMO study: A multicenter assessment of nonmotor symptoms and their impact on quality of life in Parkinson's disease.

We performed a multicenter survey using a semistructured interview in 1,072 consecutive patients with Parkinson's disease (PD) enrolled during 12 months in 55 Italian centers to assess the prevalence of nonmotor symptoms (NMSs), their association with cognitive impairment, and the impact on patients' quality of life (QoL). We found that 98.6% of patients with PD reported the presence of NMSs.

The purpose of our study was to determine the incidence of stroke, case-fatality rate and disability at 1 year in the Valley of Aosta (Italy) in the years 2004 and 2005. All suspected strokes occurring between January 1, 2004, and December 31, 2005, in the resident population of the Valley of Aosta were identified according to the WHO criteria for stroke and included in a stroke registry (Cerebrovascular Aosta Registry, CARe) after revision by a clinical panel. Multiple overlapping sources were used to ascertain the cases.

Risk factors for a first epileptic seizure after stroke: a case control study.

Introduction: The risk of seizures increases after stroke, but not all risk factors are known. We aimed to identify factors that increase the risk of a first seizure after a stroke.

Methods: Multicenter case-control study of 161 patients with a first seizure after stroke (105 provoked/acute and 56 unprovoked/remote symptomatic) matched to 279 hospital stroke controls by center, gender, age and timing of stroke.

Vertebral artery dissection complicated by basilar artery occlusion successfully treated with intra-arterial thrombolysis: three case reports.

Cervical artery dissection is an important cause of stroke in young patients and accounts of 10%-20% of stroke or TIA in patients aged less than 50 years. Basilar artery occlusion (BAO) is an infrequent cause of acute stroke, which invariably leads to death or long-term disability if not recanalized. We describe three patients with BAO caused by vertebral dissection, successfully treated with intra-arterial thrombolysis.
