A new association: acute macular neuroretinopathy in acute optic neuritis.

Acta Ophthalmol 2019 Feb 13. Epub 2019 Feb 13.

Clinical Research Department, Fondation Ophtalmologique Adolphe de Rothschild, Paris, France.

Background: Acute optic neuritis (AON) is a common optic nerve disease leading to retrograde degeneration of optic nerve axons, reflected by thinning of the inner retinal layers on optical coherence tomography. On the contrary, acute macular neuroretinopathy (AMN) type 2 is a rare outer retinal disorder that leads to thinning of the outer nuclear layers and is diagnosed by multimodal imaging. The aim of this study was to report a new association between these two diseases. Read More

Measuring network disruption in neurodegenerative diseases: New approaches using signal analysis.

J Neurol Neurosurg Psychiatry 2019 Feb 13. Epub 2019 Feb 13.

Academic Unit of Neurology, Trinity College Dublin, the University of Dublin, Dublin, Ireland

Advanced neuroimaging has increased understanding of the pathogenesis and spread of disease, and offered new therapeutic targets. MRI and positron emission tomography have shown that neurodegenerative diseases including Alzheimer's disease (AD), Lewy body dementia (LBD), Parkinson's disease (PD), frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS) are associated with changes in brain networks. However, the underlying neurophysiological pathways driving pathological processes are poorly defined. Read More

Abnormal effector and regulatory T cell subsets in paediatric-onset multiple sclerosis.

Brain 2019 Feb 12. Epub 2019 Feb 12.

Neuroimmunology Unit, Department of Neurology and Neurosurgery, Montreal Neurological Institute, McGill University, 3801 University Street, Suite # 111, Montreal, Quebec, Canada.

Elucidation of distinct T-cell subsets involved in multiple sclerosis immune-pathophysiology continues to be of considerable interest since an ultimate goal is to more selectively target the aberrant immune response operating in individual patients. While abnormalities of both effector (Teff) and regulatory (Treg) T cells have been reported in patients with multiple sclerosis, prior studies have mostly assessed average abnormalities in either limb of the immune response, rather than both at the same time, which limits the ability to evaluate the balance between effectors and regulators operating in the same patient. Assessing both phenotypic and functional responses of Teffs and Tregs has also proven important. Read More

Evidence of early microstructural white matter abnormalities in multiple sclerosis from multi-shell diffusion MRI.

Neuroimage Clin 2019 Jan 30;22:101699. Epub 2019 Jan 30.

Athinoula A. Martinos Center for Biomedical Imaging and Harvard Medical School, Boston, MA, USA.; Department of Biomedicine and Prevention, University of Rome Tor Vergata, Rome, Italy. Electronic address:

Irreversible white matter (WM) damage, including severe demyelination and axonal loss, is a main determinant of long-term disability in multiple sclerosis (MS). Non-invasive detection of changes in microstructural WM integrity in the disease is challenging since commonly used imaging metrics lack the necessary sensitivity, especially in the early phase of the disease. This study aims at assessing microstructural WM abnormalities in early-stage MS by using ultra-high gradient strength multi-shell diffusion MRI and the restricted signal fraction (FR) from the Composite Hindered and Restricted Model of Diffusion (CHARMED), a metric sensitive to the volume fraction of axons.

Electronic address:

Background: The number of white matter lesions (WML) in brain MRI is the most established paraclinical tool to support the diagnosis of multiple sclerosis (MS) and to monitor its course. Diagnostic criteria have stipulated a minimum detectable diameter of 3 mm per WML, although this threshold is not evidence-based. We aimed to provide a rationale for a WML size threshold for three-dimensional MRI sequences at 3 T by comparing patients with relapsing-remitting MS (RRMS) to control subjects (CS). Read More

Expression of Translocator Protein and [18F]-GE180 Ligand Uptake in Multiple Sclerosis Animal Models.

Cells 2019 Jan 28;8(2). Epub 2019 Jan 28.

Department of Anatomy, 39071 Rostock University Medical Center, Rostock, Germany.

Positron emission tomography (PET) ligands targeting the translocator protein (TSPO) represent promising tools to visualize neuroinflammation in multiple sclerosis (MS). Although it is known that TSPO is expressed in the outer mitochondria membrane, its cellular localization in the central nervous system under physiological and pathological conditions is not entirely clear. The purpose of this study was to assess the feasibility of utilizing PET imaging with the TSPO tracer, [18F]-GE180, to detect histopathological changes during experimental demyelination, and to determine which cell types express TSPO.

Hacettepe University School of Medicine, Department of Radiology, Ankara, Turkey.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system and one of the leading causes of disability in young adults. While some patients with MS have a benign course in which they develop limited disability even after many years, other patients have a rapidly progressive course resulting in severe disability. However, the progression of the disease, particularly disability, is currently a predictable course with neuroimaging features to some extend. Read More

Tracking Neural Progenitor Cell Migration in the Rodent Brain Using Magnetic Resonance Imaging.

Front Neurosci 2018 11;12:995. Epub 2019 Jan 11.

Molecular and Cellular Imaging Laboratory, Department of Radiology, Michigan State University, East Lansing, MI, United States.

The study of neurogenesis and neural progenitor cells (NPCs) is important across the biomedical spectrum, from learning about normal brain development and studying disease to engineering new strategies in regenerative medicine. In adult mammals, NPCs proliferate in two main areas of the brain, the subventricular zone (SVZ) and the subgranular zone, and continue to migrate even after neurogenesis has ceased within the rest of the brain. In healthy animals, NPCs migrate along the rostral migratory stream (RMS) from the SVZ to the olfactory bulb, and in diseased animals, NPCs migrate toward lesions such as stroke and tumors.

Pathophysiological and cognitive mechanisms of fatigue in multiple sclerosis.

J Neurol Neurosurg Psychiatry 2019 Jan 25. Epub 2019 Jan 25.

Translational Neuromodeling Unit (TNU), Institute for Biomedical Engineering, University of Zurich and ETH Zurich, Zurich, Switzerland.

Fatigue is one of the most common symptoms in multiple sclerosis (MS), with a major impact on patients' quality of life. Currently, treatment proceeds by trial and error with limited success, probably due to the presence of multiple different underlying mechanisms. Recent neuroscientific advances offer the potential to develop tools for differentiating these mechanisms in individual patients and ultimately provide a principled basis for treatment selection.

Progressive Multifocal Leukoencephalopathy in the Absence of Typical Radiological Changes: Can We Make a Diagnosis?

Am J Case Rep 2019 Jan 24;20:101-105. Epub 2019 Jan 24.

College of Medicine, King Saud bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia.

BACKGROUND Progressive multifocal leukoencephalopathy (PML) is a serious opportunistic infectious disease with high morbidity and mortality. Its incidence in multiple sclerosis (MS) patients has risen since the introduction of disease modifying drugs. In the absence of a specific treatment, the outcome depends heavily on early diagnosis, which illustrates the importance of the role of characteristic brain magnetic resonance imaging (MRI).

Temporal evolution of acute multiple sclerosis lesions on serial sodium (Na) MRI.

Mult Scler Relat Disord 2019 Jan 17;29:48-54. Epub 2019 Jan 17.

Department of Neurology, Universitätsmedizin Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany. Electronic address:

Background: Several studies have reported the characteristics of acute multiple sclerosis (MS) lesions on diffusion-weighted magnetic resonance imaging (DWI MRI). Current publications reported a transient reduction of the apparent diffusion coefficient (ADC) delineating an early phase of lesion evolution, before increased diffusion occurs in parallel to blood-brain-barrier (BBB) breakdown. Sodium MRI might provide another perspective on lesion development, but clinical applications have been limited to high field MR systems. Read More

Demyelination precedes axonal loss in the transneuronal spread of human neurodegenerative disease.

Brain 2019 Feb;142(2):426-442

Save Sight Institute, Sydney Medical School, The University of Sydney, Sydney, Australia.

The spread of neurodegeneration through the human brain network is reported as underlying the progression of neurodegenerative disorders. However, the exact mechanisms remain unknown. The human visual pathway is characterized by its unique hierarchical architecture and, therefore, represents an ideal model to study trans-synaptic degeneration, in contrast to the complexity in neural connectivity of the whole brain.

Manganese Enhanced MRI for Use in Studying Neurodegenerative Diseases.

Front Neural Circuits 2018 7;12:114. Epub 2019 Jan 7.

Laboratory of Functional and Molecular Imaging, National Institute of Neurological Disorders and Stroke (NINDS), National Institutes of Health, Bethesda, MD, United States.

MRI has been extensively used in neurodegenerative disorders, such as Alzheimer's disease (AD), frontal-temporal dementia (FTD), mild cognitive impairment (MCI), Parkinson's disease (PD), Huntington's disease (HD) and amyotrophic lateral sclerosis (ALS). MRI is important for monitoring the neurodegenerative components in other diseases such as epilepsy, stroke and multiple sclerosis (MS). Manganese enhanced MRI (MEMRI) has been used in many preclinical studies to image anatomy and cytoarchitecture, to obtain functional information in areas of the brain and to study neuronal connections.

Novel imaging phantom for accurate and robust measurement of brain atrophy rates using clinical MRI.

Neuroimage Clin 2019 Jan 4;21:101667. Epub 2019 Jan 4.

Department of Radiology and Nuclear Medicine, VU University Medical Center, Amsterdam, the Netherlands.

Brain volume loss, or atrophy, has been proven to be an important characteristic of neurological diseases such as Alzheimer's disease and multiple sclerosis. To use atrophy rate as a reliable clinical biomarker and to increase statistical power in clinical treatment trials, measurement variability needs to be minimized. Among other sources, systematic differences between different MR scanners are suspected to contribute to this variability. Read More

Association between pathological and MRI findings in multiple sclerosis.

Lancet Neurol 2019 Feb;18(2):198-210

Neuroimaging Research Unit and Department of Neurology, Institute of Experimental Neurology, Division of Neuroscience, San Raffaele Scientific Institute, Vita-Salute San Raffaele University, Milan, Italy.

Pathological evaluation is the gold standard for identifying processes related to multiple sclerosis that explain disease manifestations, and for guiding the development of new treatments. However, there are limitations to the techniques used, including the small number of donors available, samples often representing uncommon cases, and impossibility of follow-up. Correlative studies have demonstrated that MRI is sensitive to the different pathological substrates of multiple sclerosis (inflammation, demyelination, and neuro-axonal loss). Read More

APT-weighted MRI: Techniques, current neuro applications, and challenging issues.

J Magn Reson Imaging 2019 Jan 20. Epub 2019 Jan 20.

Division of MR Research, Department of Radiology, Johns Hopkins University, Baltimore, Maryland, USA.

Amide proton transfer-weighted (APTw) imaging is a molecular MRI technique that generates image contrast based predominantly on the amide protons in mobile cellular proteins and peptides that are endogenous in tissue. This technique, the most studied type of chemical exchange saturation transfer imaging, has been used successfully for imaging of protein content and pH, the latter being possible due to the strong dependence of the amide proton exchange rate on pH. In this article we briefly review the basic principles and recent technical advances of APTw imaging, which is showing promise clinically, especially for characterizing brain tumors and distinguishing recurrent tumor from treatment effects.
