Separating vascular and neuronal effects of age on fMRI BOLD signals [PDF]
arXiv, 2019 Accurate identification of brain function is necessary to understand the
neurobiology of cognitive ageing, and thereby promote well-being across the
lifespan. A common tool used to investigate neurocognitive ageing is functional
magnetic resonance imaging (fMRI). However, although fMRI data are often
interpreted in terms of neuronal activity, the blood-arxiv Dual‐Phase C‐11 PiB PET Images for Detecting Tau Pathology in Cerebral Amyloid Angiopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background
Cerebral amyloid angiopathy (CAA) is a major cause of lobar intracerebral hemorrhage and cognitive dysfunction in the elderly, and frequently coexists with Alzheimer's disease and tau pathology. Dual‐phase 11C‐PiB PET detects amyloid deposition and cerebral perfusion changes and may have diagnostic value for identifying tau in CAA ...Meng‐Ting Chiang, Chia‐Ju Liu, Bo‐Ching Lee, Ruoh‐Fang Yen, Hsin‐Hsi Tsai +4 morewiley +1 more sourceMusic Interventions in Hyperacute and Acute Stroke Patients: A Randomized Controlled Pilot Feasibility Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective
Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute Jeffrey J.

Nature Communications, 2016 Multifactorial mechanisms underlying late-onset Alzheimer’s disease (LOAD) are poorly characterized from an integrative perspective.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective
Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI.
