Pediatric Neurotropic Infection Alters Synaptic Development In The Developing Brain, Anuoluwapo Grace Fadare, Yashika S. Kamte, Manish N. Chandwani, Lauren A. O'Donnell

Rowan-Virtua Research Day

Many neurotropic viruses cause more significant pathology in younger hosts as their brains are still developing. This experiment asked how central nervous system (CNS) viral-infections affect the development of synapses in the pediatric brain during infection and post-infection. Synaptogenesis is at its peak in pediatric mice (10 days old) and we hypothesized that a neurotropic infection could disrupt synaptic proteins. We used a transgenic mouse model where measles virus (MV) infects only mature neurons, leading us to question whether synapses were impacted. We examined synaptic markers in the cerebellum and hippocampus in MV-infected and uninfected mice 9 days and 90 …

A Moyamoya Case Report On A Patient With Slurred Speech And Right-Hand Weakness, Priyasha Suri, Mery Bartl, Don Rajan, Natalia Pinto, Daniela Hernandez

Research Symposium

Background: Moyamoya angiopathy (MMA) is a cerebrovascular disease affecting about one in a million people. It is characterized by progressive stenosis of the terminal portion of the internal carotid arteries leading to cerebral hypo-perfusion which in turn induces neo-angiogenesis in the deep parts of the brain. Patients are predisposed to ischemic and hemorrhagic strokes. Diagnosis is usually made with magnetic resonance imaging (MRI) and a magnetic resonance angiogram (MRA) to evaluate the brain and its blood vessels. Symptomatic patients should undergo surgical interventions. A few studies have shown that the superficial temporal artery to middle cerebral artery bypass combined with …

Journal Club: Glymphatic System In Neurodegenerative Diseases, Ronald G. Lott Iii, Xavier Zonna, Samuel Wlasowicz

Advances in Clinical Medical Research and Healthcare Delivery

Neurodegenerative diseases such as Alzheimer's Disease impact a multitude of individuals worldwide. The neural Glymphatic system is a relatively newly discovered cellular transport pathway within the brain that has been implicated in neurodegenerative diseases. This article serves to provide a journal club review of current literature on the Glymphatic system to raise awareness of this system and its potential for future treatment and prevention of neurodegenerative conditions.

Utility And Yield Of Genetic Testing Leading To A Definitive Neuromuscular Or Neuropathic Diagnosis At A Rural Outpatient Neurology Clinic Affiliated With A University Health Center In West Virginia Over 4 Years., Holly Farkosh, Dominika Lozowska

Marshall Journal of Medicine

Introduction

Clinicians are increasingly relying on genetic testing to pinpoint definite diagnoses. A more general diagnosis of neuropathy or neuromuscular disease like myopathy can be narrowed down substantially using genetic testing. Because carrier status is of utmost importance in reproductive matters, pathogenic results can prognosticate the future course of the illness and help plan ahead for treatment and social supports. Given the expense of genetic testing, it is important to assess the cost-benefit ratio to determine whether it is worthwhile to collect genetic samples. The purpose of the study was to determine the likelihood of obtaining a conclusive confirmatory diagnosis …

The Comparative Efficacy Of Amantadine Vs. Lcig Therapy For The Treatment Of Levodopa-Induced Dyskinesia In Patients With Advanced Parkinson's Disease, Katelynn Timony

Capstone Showcase

Introduction: Though levodopa-carbidopa therapy remains the gold standard of Parkinson’s disease (PD) treatment to this day, patients often experience increased dyskinetic activity as a result of long-term treatment; known as levodopa-induced dyskinesia (LID); the mechanism of which is not completely understood. In this review, the efficacy of two adjunct treatments for LID are compared: 1) the concomitant administration of amantadine, an antiviral medication with antidyskinetic properties; and 2) a new form of levodopa administration in the form of an intestinal gel delivered straight via a device much like an insulin pump.

Methods: Two systematic literature searches of primary, peer-reviewed articles …

Medical Resource Utilization Of Outpatient Care For Children With Neurofibromatosis Type 1, Rabia Idrees, Michael Fisher, Rachel Hachen, Brian Callaghan, Robert A. Avery

GW Research Days 2016 - 2020

Background:

Neurofibromatosis Type 1 (NF1) is an autosomal dominant syndrome with manifestations affecting the central nervous system, musculoskeletal system, peripheral nervous system, and cognitive/behavioral functions. Many of these manifestations persist throughout life and require medical/surgical interventions.

The resource utilization and economic burden of caring for children with NF1 is unknown. Prior research has inherent selection bias and does not accurately reflect the incidence/resource utilization of morbidities. In order to identify which disease manifestations are in the most need of improved clinical algorithms and novel therapeutics, the frequency/type of resources utilized (i.e., diagnostic imaging and specialty visits) must be determined.

Amyotrophic Lateral Sclerosis, The Primary Motor Neuron Disease, Jacob P. Naumann

The Downtown Review

Amyotrophic lateral sclerosis is a degenerative neurological disease that damages nerve cells in the brain, in particular the neurons that are involved in voluntary muscle movements. Internationally the disorder is also known as Charcot’s disease and motor neuron disease. In the United States, amyotrophic lateral sclerosis is often referred to as Lou Gehrig’s disease, motor neuron disease, and more colloquially ALS. Amyotrophic Lateral Sclerosis is the most prominent of the five motor neuron diseases, distinguishing itself from the others through degeneration of both upper motor neurons (UMN) and lower motor neurons (LMN) respectively. The “Father of neurology” Jean-Marie Charcot founded …

Novel Advances In Alzheimer's Disease, Jacob P. Naumann

The Downtown Review

Alzheimer’s disease, the most common form of dementia in adults, is a progressive degenerative neurological disease that affects memory, cognition, and behavior. Dr. Alois Alzheimer discovered and diagnosed the irreversible disease in 1906 after documenting the famous case of Auguste Deter.¹ Since the discovery of the disease, numerous advances have made it possible to not only better understand the causal factors, but also to improve the medical diagnosis and preventative measures that healthcare providers can implement. For the first time since 1984, the National Institute on Aging (NIAA) and the Alzheimer’s Association (AA) proposed and published new diagnostic guideline …

The Therapeutic Role Of Turmeric In Treatment And Prevention Of Alzheimer’S Disease, Rylan M. Mcquade

Selected Honors Theses

As a devastating neurological condition that expends millions of lives each year, Alzheimer’s disease (AD) is a subject of intense investigation.¹ Although AD has been known for over a century, the precise mechanisms that underlie AD pathogenesis and development are still poorly understood. The Alzheimer phenotype is typified by extracellular amyloid-beta (Aβ) plaques and intracellular neurofibrillary tangles (NFTs), causing researchers to notice several key enzymes implicated in this process.¹ Most notable are β and γ secretases (which drive Aβ plaque production) and phospholipase

A₂ (which stimulates major cascade activation through the specific cleavage of fatty acyl esters). …

Neurology In The 21st Century: Contemporary State Of Diagnostics And Therapeutics, Saad Shafqat, Mohammad Wasay

Department of Medicine

Although neurological disease has been recognized since antiquity, neurology as a systematic clinical discipline is less than 130 years old. Neurological practice has traditionally been constrained by the complexity of the human nervous system, which has been slow to yield its secrets. Over the last three decades, however, clinical neurology has been transformed in terms of both diagnostics and therapeutics and now marches in lockstep with the cutting edge of medicine. Efficacious treatments are now available for the majority of neurological diseases, including epilepsy, migraine, Guillain-Barre syndrome, Parkinson's disease, multiple sclerosis, and ischemic stroke. This neurological revolution has been enabled …
