Impairments In Attention In Occasionally Snoring Children: An Event-Related Potential Study., Maria E. Barnes, Elizabeth A. Huss, Krista N. Garrod, Eric Van Ray, Ehab Dayyat, David Gozal, Dennis L. Molfese

Faculty and Staff Scholarship

Objective: To determine whether minimal snoring is benign in children. Procedure: 22 rarely snoring children (mean age = 6.9 years, 11 females) and age- and sex-matched controls participated in an auditory oddball task wearing 128-electrode nets. Parents completed the Conners Parent Rating Scales–Revised Long (CPRS–R:L). Results: Snorers scored significantly higher on four CPRS-R:L subscales. Stepwise regression indicated that two ERP variables from a region of the ERP that peaked at 844 msec post-stimulus onset predicted CPRS-R:L Attention Deficit Hyperactivity Disorder (ADHD) Index scores. Conclusions: Occasional snorers, according to parental report, do exhibit ADHD-like behaviors. Basic sensory processing is longer than …

Human Amniotic Fluid Stem Cells Do Not Differentiate Into Dopamine Neurons In Vitro Or After Transplantation In Vivo., Angela E Donaldson, Jingli Cai, Ming Yang, Lorraine Iacovitti

Farber Institute for Neuroscience Faculty Papers

Although embryonic stem (ES) cells can generate dopamine (DA) neurons that are potentially useful as a cell replacement therapy in Parkinson's disease (PD), associated ethical and practical concerns remain major stumbling blocks to their eventual use in humans. In this study, we examined human amniotic fluid stem (hAFS) cells derived from routine amniocenteses for their potential to give rise to DA neurons in vitro and following transplantation into the 6-hydroxydopamine-lesioned rat brain. We show that undifferentiated hAFS cells constitutively expressed mRNAs and proteins typical of stem cells but also cell derivatives of all three germ layers, including neural progenitors/neurons (nestin, …

Relating Visual To Verbal Semantic Knowledge: The Evaluation Of Object Recognition In Prosopagnosia, Jason J. S. Barton, Hashim-M Hanif, Sohi Ashraf

Section of Neurology

Assessment of face specificity in prosopagnosia is hampered by difficulty in gauging pre-morbid expertise for non-face object categories, for which humans vary widely in interest and experience. In this study, we examined the correlation between visual and verbal semantic knowledge for cars to determine if visual recognition accuracy could be predicted from verbal semantic scores. We had 33 healthy subjects and six prosopagnosic Patients first rated their own knowledge of cars. They were then given a test of verbal semantic knowledge that presented them with the names of car models, to which they were to match the manufacturer. Lastly, they …

Mechanisms Of Primary Axonal Damage In A Viral Model Of Multiple Sclerosis., Jayasri Das Sarma, Lawrence C. Kenyon, Susan T. Hingley, Kenneth S. Shindler

Department of Neurology Faculty Papers

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the CNS. Recent studies have demonstrated that significant axonal injury also occurs in MS patients and correlates with neurological dysfunction, but it is not known whether this neuronal damage is a primary disease process, or occurs only secondary to demyelination. In the current studies, neurotropic strains of mouse hepatitis virus (MHV) that induce meningitis, encephalitis, and demyelination in the CNS, an animal model of MS, were used to evaluate mechanisms of axonal injury. The pathogenic properties of genetically engineered isogenic spike protein recombinant demyelinating and nondemyelinating strains of MHV were compared. …

Dynamic Mechanical (Brush) Allodynia In Cluster Headache: A Prevalence Study In A Tertiary Headache Clinic., Michael J Marmura, Muhammad Abbas, Avi Ashkenazi

Department of Jefferson Headache Center Papers and Presentations

Cutaneous allodynia (CA) has been described in migraine and has been related to treatment failure. There are little data about the incidence of CA in other primary headache syndromes such as cluster headache (CH). The objectives of this study are to evaluate the prevalence of dynamic mechanical (brush) allodynia (BA) in CH patients attending a tertiary headache clinic, and to assess its relation to disease characteristics. Adult patients with episodic or chronic CH were recruited. We obtained demographic data and data on disease characteristics through a structured questionnaire, and tested the patients for brush allodynia BA by applying a 4 …

Disclosure Of Apoe Genotype For Risk Of Alzheimer's Disease, Peter J. Whitehouse, Melissa Barber Butson

Faculty Scholarship

BACKGROUND: The apolipoprotein E (APOE) genotype provides information on the risk of Alzheimer's disease, but the genotyping of patients and their family members has been discouraged. We examined the effect of genotype disclosure in a prospective, randomized, controlled trial. METHODS: We randomly assigned 162 asymptomatic adults who had a parent with Alzheimer's disease to receive the results of their own APOE genotyping (disclosure group) or not to receive such results (nondisclosure group). We measured symptoms of anxiety, depression, and test-related distress 6 weeks, 6 months, and 1 year after disclosure or nondisclosure. RESULTS: There were no significant differences between the …

Background: Intracranial stenosis is the most common cause of stroke among Asians. It has a poor prognosis with a high rate of recurrence. No effective medical or surgical treatment modality has been developed for the treatment of stroke due to intracranial stenosis. We aim to identify risk factors and biomarkers for intracranial stenosis and to develop techniques such as use of transcranial doppler to help diagnose intracranial stenosis in a cost-effective manner.

Methods/Design: The Karachi Intracranial Stenosis Study (KISS) is a prospective, observational, case-control study to describe the clinical features and determine the risk factors of patients with stroke due …

Prion Protein Glycosylation Is Not Required For Strain-Specific Neurotropism, Justin R. Piro, Brent T. Harris, Koren Nishina, Claudio Soto, Rodrigo Morales, Judy R. Rees, Surachai Supattapone

Dartmouth Scholarship

In this study, we tested the hypothesis that the glycosylation of the pathogenic isoform of the prion protein (PrP^Sc) might encode the selective neurotropism of prion strains. We prepared unglycosylated cellular prion protein (PrP^C) substrate molecules from normal mouse brain by treatment with PNGase F and used reconstituted serial protein cyclic misfolding amplification reactions to produce RML and 301C mouse prions containing unglycosylated PrP^Sc molecules. Both RML- and 301C-derived prions containing unglycosylated PrP^Sc molecules were infectious to wild-type mice, and neuropathological analysis showed that mice inoculated with these samples maintained strain-specific patterns of PrP …

Intravenous Inoculation Of A Bat-Associated Rabies Virus Causes Lethal Encephalopathy In Mice Through Invasion Of The Brain Via Neurosecretory Hypothalamic Fibers., Mirjam A R Preuss, Marie-Luise Faber, Gene S Tan, Michael Bette, Bernhard Dietzschold, Eberhard Weihe, Matthias J Schnell

Department of Microbiology and Immunology Faculty Papers

The majority of rabies virus (RV) infections are caused by bites or scratches from rabid carnivores or bats. Usually, RV utilizes the retrograde transport within the neuronal network to spread from the infection site to the central nervous system (CNS) where it replicates in neuronal somata and infects other neurons via trans-synaptic spread. We speculate that in addition to the neuronal transport of the virus, hematogenous spread from the site of infection directly to the brain after accidental spill over into the vascular system might represent an alternative way for RV to invade the CNS. So far, it is unknown …
