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

Guidelines for the peri-operative care of people with dementia: Guidelines from the Association of Anaesthetists.

Anaesthesia 2019 Mar 11;74(3):357-372. Epub 2019 Jan 11.

Homerton University Hospital NHS Foundation Trust, London, UK.

Ageing populations have greater incidences of dementia. People with dementia present for emergency and, increasingly, elective surgery, but are poorly served by the lack of available guidance on their peri-operative management, particularly relating to pharmacological, medico-legal, environmental and attitudinal considerations. These guidelines seek to deliver such guidance, by providing information for peri-operative care providers about dementia pathophysiology, specific difficulties anaesthetising patients with dementia, medication interactions, organisational and medico-legal factors, pre-, intra- and postoperative care considerations, training, sources of further information and care quality improvement tools.

Kufs disease due to mutation of CLN6: clinical, pathological and molecular genetic features.

Brain 2019 Jan;142(1):59-69

Consultant in Neuropathology, Centro Hospitalar São João, Porto, Portugal.

Kufs disease is the major adult form of neuronal ceroid lipofuscinosis, but is rare and difficult to diagnose. Diagnosis was traditionally dependent on the demonstration of characteristic storage material, but distinction from normal age-related accumulation of lipofuscin can be challenging. Mutation of CLN6 has emerged as the most important cause of recessive Kufs disease but, remarkably, is also responsible for variant late infantile ceroid lipofuscinosis. Read More

Systematic Review on Resting-State EEG for Alzheimer's Disease Diagnosis and Progression Assessment.

Dis Markers 2018 4;2018:5174815. Epub 2018 Oct 4.

Institut national de la recherche scientifique (INRS-EMT), University of Québec, Montreal, Canada.

Alzheimer's disease (AD) is a neurodegenerative disorder that accounts for nearly 70% of the more than 46 million dementia cases estimated worldwide. Although there is no cure for AD, early diagnosis and an accurate characterization of the disease progression can improve the quality of life of AD patients and their caregivers. Currently, AD diagnosis is carried out using standardized mental status examinations, which are commonly assisted by expensive neuroimaging scans and invasive laboratory tests, thus rendering the diagnosis time consuming and costly.

Combining EEG signal processing with supervised methods for Alzheimer's patients classification.

BMC Med Inform Decis Mak 2018 05 31;18(1):35. Epub 2018 May 31.

IRCCS Centro Neurolesi "Bonino-Pulejo", Contrada Casazza, SS113, Messina, 98124, Italy.

Background: Alzheimer's Disease (AD) is a neurodegenaritive disorder characterized by a progressive dementia, for which actually no cure is known. An early detection of patients affected by AD can be obtained by analyzing their electroencephalography (EEG) signals, which show a reduction of the complexity, a perturbation of the synchrony, and a slowing down of the rhythms.

Methods: In this work, we apply a procedure that exploits feature extraction and classification techniques to EEG signals, whose aim is to distinguish patient affected by AD from the ones affected by Mild Cognitive Impairment (MCI) and healthy control (HC) samples. Read More

De Novo Myoclonic Status Epilepticus After Benzodiazepine Withdrawal.

Clin Neuropharmacol 2018 Jul/Aug;41(4):142-144

Hospital Israelita Albert Einstein, São Paulo, Brazil.

Myoclonic status epilepticus (MSE) in patients without epilepsy, or de novo MSE, is a rare condition associated with several acute symptomatic etiologies, including drugs and toxins. We describe a 94-year-old woman with Alzheimer dementia and long use of mirtazapine 30 mg/d and alprazolam 1 mg/d who developed MSE approximately 24 hours after abrupt discontinuation of alprazolam. The patient was taking sulfamethoxazole/trimethoprim for urinary tract infection, diagnosed 2 weeks before admission. Read More

Design of optimal nonlinear network controllers for Alzheimer's disease.

PLoS Comput Biol 2018 05 24;14(5):e1006136. Epub 2018 May 24.

Biomedical Engineering Graduate Program, University of Calgary, Calgary, Alberta, Canada.

Brain stimulation can modulate the activity of neural circuits impaired by Alzheimer's disease (AD), having promising clinical benefit. However, all individuals with the same condition currently receive identical brain stimulation, with limited theoretical basis for this generic approach. In this study, we introduce a control theory framework for obtaining exogenous signals that revert pathological electroencephalographic activity in AD at a minimal energetic cost, while reflecting patients' biological variability.

Circadian and Brain State Modulation of Network Hyperexcitability in Alzheimer's Disease.

eNeuro 2018 Mar-Apr;5(2). Epub 2018 May 17.

Centre for Discovery Brain Sciences, University of Edinburgh, Edinburgh, EH8 9JZ, United Kingdom.

Network hyperexcitability is a feature of Alzheimer' disease (AD) as well as numerous transgenic mouse models of AD. While hyperexcitability in AD patients and AD animal models share certain features, the mechanistic overlap remains to be established. We aimed to identify features of network hyperexcitability in AD models that can be related to epileptiform activity signatures in AD patients. Read More

Automatic segmentation of stereoelectroencephalography (SEEG) electrodes post-implantation considering bending.

Int J Comput Assist Radiol Surg 2018 Jun 7;13(6):935-946. Epub 2018 May 7.

Wellcome/EPSRC Centre for Interventional and Surgical Sciences, UCL, London, UK.

Purpose: The accurate and automatic localisation of SEEG electrodes is crucial for determining the location of epileptic seizure onset. We propose an algorithm for the automatic segmentation of electrode bolts and contacts that accounts for electrode bending in relation to regional brain anatomy.

Methods: Co-registered post-implantation CT, pre-implantation MRI, and brain parcellation images are used to create regions of interest to automatically segment bolts and contacts. Read More

Institute for Learning & Brain Sciences, University of Washington, Seattle, WA, USA; Department of Physics, University of Washington, Seattle, WA, USA.

Magnetoencephalography (MEG) records weak magnetic fields outside the human head and thereby provides millisecond-accurate information about neuronal currents supporting human brain function. MEG and electroencephalography (EEG) are closely related complementary methods and should be interpreted together whenever possible. This manuscript covers the basic physical and physiological principles of MEG and discusses the main aspects of state-of-the-art MEG data analysis. Read More

Creutzfeldt-Jakob Disease Presenting as Expressive Aphasia and Nonconvulsive Status Epilepticus.

Case Rep Crit Care 2018 14;2018:5053175. Epub 2018 Feb 14.

University of Nevada School of Medicine, Reno, NV, USA.

Creutzfeldt-Jakob disease (CJD), the most common form of human prion diseases, is a fatal condition with a mortality rate reaching 85% within one year of clinical presentation. CJD is characterized by rapidly progressive neurological deterioration in combination with typical electroencephalography (EEG) and magnetic resonance imaging (MRI) findings and positive cerebrospinal spinal fluid (CSF) analysis for 14-3-3 proteins. Unfortunately, CJD can have atypical clinical and radiological presentation in approximately 10% of cases, thus making the diagnosis often challenging. Read More

Occipital epilepsy versus progressive myoclonic epilepsy in a patient with continuous occipital spikes and photosensitivity in electroencephalogram: A case report.

Medicine (Baltimore) 2018 Apr;97(15):e0299

Department of Neurology and Neuroscience Center, The First Hospital of JiLin University, Changchun.

Introduction: Progressive myoclonic epilepsy (PME) is rare epilepsy syndrome. Although EEG is a useful neurophysiological technique in the evaluation of epilepsy, few EEG abnormalities have been described in PME. So, how to use EEG hints to establish the suspected diagnosis of PME as soon as possible should be addressed. Read More

Phosphorylation of Tau protein correlates with changes in hippocampal theta oscillations and reduces hippocampal excitability in Alzheimer's model.

J Biol Chem 2018 06 9;293(22):8462-8472. Epub 2018 Apr 9.

the Department of Psychiatry, Douglas Mental Health University Institute, McGill University, Quebec H4H 1R3, Canada.

Tau hyperphosphorylation at several sites, including those close to the microtubule domain region (MDr), is considered a key pathological event in the development of Alzheimer's disease (AD). Recent studies indicate that at the very early stage of this disease, increased phosphorylation in Tau's MDr domain correlates with reduced levels of neuronal excitability. Mechanistically, we show that pyramidal neurons and some parvalbumin-positive interneurons in 1-month-old triple-transgenic AD mice accumulate hyperphosphorylated Tau protein and that this accumulation correlates with changes in theta oscillations in hippocampal neurons.

Testing Mean Differences among Groups: Multivariate and Repeated Measures Analysis with Minimal Assumptions.

Multivariate Behav Res 2018 May-Jun;53(3):348-359. Epub 2018 Mar 22.

d Department of Neurology, Christian Doppler Medical Centre and Centre for Cognitive Neuroscience , Paracelsus Medical University.

To date, there is a lack of satisfactory inferential techniques for the analysis of multivariate data in factorial designs, when only minimal assumptions on the data can be made. Presently available methods are limited to very particular study designs or assume either multivariate normality or equal covariance matrices across groups, or they do not allow for an assessment of the interaction effects across within-subjects and between-subjects variables. We propose and methodologically validate a parametric bootstrap approach that does not suffer from any of the above limitations, and thus provides a rather general and comprehensive methodological route to inference for multivariate and repeated measures data.

This study addresses the problem of Alzheimer's disease (AD) diagnosis with Electroencephalography (EEG). The use of EEG as a tool for AD diagnosis has been widely studied by comparing EEG signals of AD patients only to those of healthy subjects. By contrast, we perform automated EEG diagnosis in a differential diagnosis context using a new database, acquired in clinical conditions, which contains EEG data of 169 patients: subjective cognitive impairment (SCI) patients, mild cognitive impairment (MCI) patients, possible Alzheimer's disease (AD) patients, and patients with other pathologies.
