Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.

A singular nonlinear boundary value problem [PDF]
Pacific Journal of Mathematics, 1978 We show that the following nonlinear boundary-value problem has a positive solution: \[ \ddot{y}-y+yF(y^2,t)=0,y(0)=0=\lim_{t\to \infty}\,y(t),\dot{y}(0) \mathrm{ finite.} \] We assume that \(F\) is continuous for \(t>0\), \(y^2 \geq 0\); \(F>0\) for \(y^2 >0\); and \(\eta^{-\delta}F(\eta ,t)\) is strictly increasing in \(\eta\) for some \(\delta>0 ...

Digital Cognitive Phenotyping for Differential Diagnosis and Monitoring in Neurological Conditions
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To assess the utility, accessibility, and equivalence to supervised scales of online cognitive assessment in older individuals with cognitive impairment. Methods Patients with Alzheimer's disease (AD, n = 31), idiopathic normal pressure hydrocephalus (iNPH, n = 26), and traumatic brain injury (TBI, n = 23) completed online cognitive ...

Arthritis Care &Research, EarlyView.Objective Systemic lupus erythematosus (SLE) is a heterogenous inflammatory condition with widely varying global prevalence estimates. The frequency of SLE in the general population of Australia has been reported to be notably lower than contemporary estimates in countries such as the United States or United Kingdom, at 19 to 39 per 100,000 as opposed ...

Positive Solutions to Singular and Delay Higher-Order Differential Equations on Time Scales
Boundary Value Problems, 2009 We are concerned with singular three-point boundary value problems for delay higher-order dynamic equations on time scales. Theorems on the existence of positive solutions are obtained by utilizing the fixed point theorem of cone expansion and ...
