Early perfusion changes in multiple sclerosis patients as assessed by MRI using arterial spin labeling

Acta Radiologica Open, 2019
Background Gadolinium-perfusion magnetic resonance (MR) identifies gray matter abnormalities in early multiple sclerosis (MS), even in the absence of structural differences.

Unusual MRI findings of dural arteriovenous fistula: Isolated perfusion lesions mimicking TIA

BMC Neurology, 2012
Background The diagnosis of transient ischemic attack (TIA) based on clinical history and objective findings, even including multiparametric MRI, can be misleading.

Arterial Spin‐Labeling MRI at the Cortical‐CSF Interface: A Novel Biomarker in Alzheimer Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background/Objective Arterial spin‐labeling (ASL) MRI can measure perfusion signal adjacent to CSF spaces and may provide information regarding CSF‐adjacent water transport physiology. We developed an automated pipeline to extract cortical‐CSF interface (IF) perfusion for comparison between Alzheimer disease (AD) and cognitively normal ...

A claustro-cortical loop times state transitions for flexible behavior

Metastable dynamics, in which neural activity moves between transiently stable patterns, have been proposed to underlie the real-time coordination on which the brain’s cognitive and behavioral functions depend 1–3 .

Posterior Disconnection Syndrome in Early‐Stage Adult‐Onset Cerebral Adrenoleukodystrophy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Adult‐onset cerebral adrenoleukodystrophy is potentially treatable but often difficult to recognize before advanced cerebral involvement. Herein, we describe three men with early‐stage disease who initially presented with subtle visual complaints rather than subcortical dementia. Targeted neuropsychological testing revealed higher‐order visual

Pulse transit time respiratory swing as a diagnostic test for obstructive sleep apnoea in children—An observational study

Frontiers in Neurology
BackgroundPulse transit time (PTT) has been identified as a potentially useful tool for diagnosing obstructive sleep apnoea (OSA) due to its high sensitivity in detecting cortical arousals.

Intravoxel incoherent motion perfusion in patients with Moyamoya disease: comparison with O-gas positron emission tomography

Acta Radiologica Open, 2019
Background Intravoxel incoherent motion magnetic resonance imaging (IVIM) enables non-invasive measurement of brain perfusion. Purpose To investigate whether IVIM could be used to evaluate the hemodynamic disturbance of Moyamoya disease (MMD) by ...

CSF Cytokine Network Organization Predicts Progression Independent of Relapse and MRI Activity in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progression independent of relapse activity is a major determinant of long‐term disability in multiple sclerosis, but its immunopathologic basis remains incompletely understood. We investigated whether relapse‐independent progression in radiologically stable relapsing–remitting multiple sclerosis is associated with distinct ...

Cortical volume reductions in men transitioning to first-time fatherhood reflect both parenting engagement and mental health risk

Cerebral Cortex
Abstract Perinatal reductions in gray matter volume have been observed in human mothers transitioning to parenthood, with preliminary evidence for similar changes in fathers. These reductions have been theorized to support adaptation to parenting, but greater investigation is needed.
