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)
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)
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 examine whether deviation from the standard intention to treat analysis has an influence on treatment effect estimates of randomised trials. DESIGN Meta-epidemiological study. DATA SOURCES Medline, via PubMed, searched between 2006 and 2010; 43 systematic reviews of interventions and 310 randomised trials were included. ELIGIBILITY(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)
BACKGROUND Headache has been reported to be the first clinical presentation in several patients with cerebral arteriovenous malformations (AVMs). Headache associated with AVMs often shows characteristics of migraine with and without aura. Angiographic characteristics of AVMs, such as their location, could determine the 'migraine-like' features of attacks.(More)
AIM Increasing evidence from experimental studies and clinical observations suggests that drugs with anticholinergic properties can cause physical and mental impairment. The aim of the present study was to evaluate the relationship between the use of drugs with anticholinergic activity and negative outcomes in older nursing home residents. METHODS We used(More)
This study aimed at determining the causes of failure of the different proposed strategies to ensure improvement of medication-overuse headache (MOH) patients, since they have not been investigated so far, especially with regard to aspects related to cognitive and behavioural aspects of symptomatic drugs overused by them. One hundred and twenty in-patients,(More)
OBJECTIVE The principal aims of the present study were to explore the prevalence of anorexia and the factors correlated to anorexia in a large population of older people living in nursing home. Secondary, we evaluated the impact of anorexia on 1-year survival. METHODS Data are from baseline evaluation of 1904 participants enrolled in the Un Link(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)
