Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Invariant Manifolds for Abstract Functional Differential Equations and Related Volterra Difference Equations in a Banach Space

Funkcialaj Ekvacioj, 2007
For abstract functional differential equations (FDE) and Volterra difference equations (VDE) in a Banach space, the local existence and smoothness of invariant manifolds, such as stable/unstable manifolds, center-stable/center-unstable manifolds and center manifolds, are established by means of the variation of constants formula in the phase space in ...

Mixed Monotone Iterative Technique for Abstract Impulsive Evolution Equations in Banach Spaces

Journal of Inequalities and Applications, 2010
By constructing a mixed monotone iterative technique under a new concept of upper and lower solutions, some existence theorems of mild -periodic ( -quasi) solutions for abstract impulsive evolution equations are obtained in ordered Banach spaces. These

On new evolution of Ri’s result via w-distances and the study on the solution for nonlinear integral equations and fractional differential equations

Advances in Difference Equations, 2018
The aim of this work is to establish a new fixed point theorem for generalized contraction mappings with respect to w-distances in complete metric spaces. An illustrative example is provided to advocate the usability of our results.

Approximate controllability of Sobolev type fractional stochastic nonlocal nonlinear differential equations in Hilbert spaces

, 2014
We introduce a new notion called fractional stochastic nonlocal condition, and then we study approximate controllability of class of fractional stochastic nonlin- ear differential equations of Sobolev type in Hilbert spaces.

Norm Continuity (fort>0) of Propagators of Arbitrary Order Abstract Differential Equations in Hilbert Spaces

Journal of Mathematical Analysis and Applications, 1996
The authors deal with the abstract Cauchy problem \[ u^{(n)} (t)+ \sum^{n-1}_{k=0} A_ku^{(k)} (t)=0,\;t\geq 0,\;u^{(k)} (0)=u_k\;(0\leq k\leq n-1), \] where \(A_k\) are densely defined closed linear operators on a complex Hilbert space. Assuming that the problem is wellposed let \(S_0\), \(S_1, \dots, S_{n-1}\) be the mappings defined by \(S_k(t)x =u_k(

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.
