Although alpha-synuclein is the main constituent of Lewy bodies, cerebrospinal fluid determination on its own does not seem fundamental for the diagnosis of synucleinopathies. We evaluated whether the combination of classical biomarkers, Aβ(1-42) , total tau, phosphorylated tau, and α-synuclein can improve discrimination of Parkinson's disease, dementia(More)
In recent years a role has been recognized for fibroblast growth factor (FGF)-2 in the pathogenesis of demyelination and the failure of remyelination in experimental models of multiple sclerosis (MS). FGF-2 levels were determined using a sensitive immunoassay in the cerebrospinal fluid (CSF) of 20 patients with clinically isolated syndrome (CIS), 40(More)
There is a great interest in developing cerebrospinal fluid (CSF) biomarkers for diagnosis and prognosis of Parkinson's disease (PD). CSF alpha synuclein (α-syn) species, namely total and oligomeric α-syn (t-α-syn and o-α-syn), have shown to be of help for PD diagnosis. Preliminary evidences show that the combination of CSF t-α-syn and classical Alzheimer's(More)
OBJECTIVE To evaluate seizures as first clinical manifestation of brain arteriovenous malformations (AVMs), in relation to angioarchitectural features of these vascular anomalies. METHODS We performed a prospective observational study, collecting records of patients with AVMs consecutively admitted to the Neurological and Neurosurgery Units of Perugia(More)
Mild cognitive impairment (MCI) is a common condition in the elderly which may remain stable along time (MCI-MCI) or evolve into Alzheimer's disease (MCI-AD) or other dementias. Cerebrospinal fluid (CSF) classical biomarkers, i.e., amyloid-β 1-42 (Aβ1-42), total tau (t-tau), and phosphorylated tau (p-tau) reflect the neuropathological changes taking place(More)
BACKGROUND AND PURPOSE Magnetization transfer ratio (MTR) technique has identified brain changes in grey and white matter in Parkinson's disease (PD), even in the early phase. However, how these tissue changes differ along the course of the illness is still unclear. This study was aimed at investigating how MTR values change from mild PD (PD1) to patients(More)
To assess the discriminating power of multiple cerebrospinal fluid (CSF) biomarkers for Parkinson's disease (PD), we measured several proteins playing an important role in the disease pathogenesis. The activities of β-glucocerebrosidase and other lysosomal enzymes, together with total and oligomeric α-synuclein, and total and phosphorylated tau, were thus(More)
Lysosomal dysfunction is thought to be a prominent feature in the pathogenetic events leading to Parkinson’s disease (PD). This view is supported by the evidence that mutations in GBA gene, coding the lysosomal hydrolase β-glucocerebrosidase (GCase), are a common genetic risk factor for PD. Recently, GCase activity has been shown to be decreased in(More)
Chronic migraine (CM) is frequently associated with medication overuse headache (MOH). The endocannabinoid system plays a role in modulating pain including headache and is involved in the common neurobiological mechanism underlying drug addiction and reward system. Anandamide (AEA) and 2-arachidonoylglycerol are the most biologically active(More)
Neuroinflammation is believed to be involved in the pathophysiological mechanisms of silent brain infarcts (SBI). However, the immunological profile of SBI has been scarcely investigated. In the context of a national research project named SILENCE, aimed at investigating clinical, biochemical and pathogenic features of SBI, we have measured the plasma(More)
