OBJECTIVE To assess the ability of 5 cerebrospinal fluid(CSF) biomarkers to differentiate between common dementia and parkinsonian disorders. DESIGN A cross-sectional, clinic-based study. PARTICIPANTS Cerebrospinal fluid samples (N=453) were obtained from healthy individuals serving as controls and from patients with Parkinson disease (PD), PD with(More)
OBJECTIVE To determine the suitability and estimate the sensitivity of an immunohistochemical (IHC) test for disease-associated prion protein (PrP(Sc)) in biopsy specimens of rectoanal mucosa-associated lymphoid tissue (RAMALT) for diagnosis of scrapie in sheep. ANIMALS 762 sheep at high risk for having scrapie and indemnified by the National Scrapie(More)
The objective was to study whether α-synuclein oligomers are altered in the cerebrospinal fluid (CSF) of patients with dementia, including Parkinson disease with dementia (PDD), dementia with Lewy bodies (DLB), and Alzheimer disease (AD), compared with age-matched controls. In total, 247 CSF samples were assessed in this study, including 71 patients with(More)
Bovine spongiform encephalopathy (BSE) is a transmissible spongiform encephalopathy of cattle, first detected in 1986 in the United Kingdom and subsequently in other countries. It is the most likely cause of variant Creutzfeldt-Jakob disease (vCJD) in humans, but the origin of BSE has not been elucidated so far. This report describes the identification and(More)
Chronic wasting disease (CWD) in Wisconsin was first identified in February 2002. By April 2005, medial retropharyngeal lymph node (RLN) tissues had been examined from over 75,000 white-tailed deer for the presence of CWD by either immunohistochemical (IHC) staining for the prion protein associated with CWD (PrP(res)) or by using enzyme-linked immunosorbent(More)
OBJECTIVE To investigate whether certain CSF biomarkers at baseline can predict future progression of motor symptoms and cognitive decline in patients with Parkinson disease (PD). METHODS Patients and controls were recruited from hospitals in southern Sweden as part of the prospective and longitudinal Swedish BioFinder Study. In the present study, we(More)
To determine the transmissibility of chronic wasting disease (CWD) to fallow deer (Dama dama) and to provide information about clinical course, lesions and suitability of currently used diagnostic procedures for detection of CWD in this species, 13 fawns were inoculated intracerebrally with CWD brain suspension from elk (n=6) or white-tailed deer (n=7).(More)
A major difference in the revised diagnostic criteria for Alzheimer's disease (AD) is the incorporation of biomarkers to support a clinical diagnosis and allow the identification of preclinical AD due to AD neuropathological processes. However, AD-specific fluid biomarkers which specifically distinguish clinical AD dementia from other dementia disorders are(More)
OBJECTIVE This study assessed the efficacy and safety of the neuronal potassium channel opener ezogabine (US adopted name; EZG)/retigabine (international nonproprietary name; RTG) as adjunctive therapy for refractory partial-onset seizures. METHODS This was a multicenter, randomized, double-blind, placebo-controlled trial in adults with ≥4 partial-onset(More)
Fourteen, 3-month-old calves were intracerebrally inoculated with the agent of chronic wasting disease (CWD) from white-tailed deer (CWDwtd) to compare the clinical signs and neuropathologic findings with those of certain other transmissible spongiform encephalopathies (TSE, prion diseases) that have been shown to be experimentally transmissible to cattle(More)
