Amyloidosis encompasses a group of disorders sharing the common feature of intercellular deposition of amyloid protein by several different pathogenetic mechanisms. Primary solitary amyloidosis, or amyloidoma, is a rare subset of amyloidosis in which amyloid deposition is focal and not secondary to a systemic process or plasma cell dyscrasia.This 84-year-old female presented with history of multiple syncopal episodes, dysphagia, and ataxia. Motor strength was 3+/5 in the right upper extremity. Rheumatoid factor, cyclic citrullinated peptide (CCP), and anti-nuclear antibody (ANA) were normal. Serum and urine immune-electrophoresis detected no abnormal bands. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a …

Spontaneous Intracranial Hypotension Complicated By Refractory Subdural Hematomas In A Patient With Coagulation Factor Xiii Deficiency, R. Gilad, S. L. Motivala, S. Khan, E. Chang, D. L. Klein, M. J. Raden

Journal Articles

© 2018 The Authors Spontaneous intracranial hypotension (SIH) is often secondary to an occult cerebrospinal fluid (CSF) leak in the neuroaxis. It is sometimes associated with chronic subdural hematomas (SDH). The authors present the case of a 61 year-old male who presented with SIH from an occult CSF leak and complicated by refractory SDH. The patient underwent treatment for SIH with multiple epidural blood patches, hydration and bed rest. In addition, he underwent evacuation of his SDH twice, once via burr hole drainage and the second via craniotomy. Once the diagnosis of coagulation factor XIII (CFXIII) deficiency was made, the …

Journal Articles

© The Author(s) (2018). Published by Oxford University Press. The success of our political institutions, environmental stewardship and evolutionary fitness all hinge on our ability to prioritize collective-interest over self-interest. Despite considerable interest in the neuro-cognitive processes that underlie group cooperation, the evidence to date is inconsistent. Several papers support models of prosocial restraint, while more recent work supports models of prosocial intuition.We evaluate these competing models using a sample of lesion patients with damage to brain regions previously implicated in intuition and deliberation. Compared to matched control participants (brain damaged and healthy controls), we found that patients with dorsolateral …

© 2018 The Authors Human Brain Mapping Published by Wiley Periodicals, Inc. Little is known about how language functional MRI (fMRI) is executed in clinical practice in spite of its widespread use. Here we comprehensively documented its execution in surgical planning in epilepsy. A questionnaire focusing on cognitive design, image acquisition, analysis and interpretation, and practical considerations was developed. Individuals responsible for collecting, analyzing, and interpreting clinical language fMRI data at 63 epilepsy surgical programs responded. The central finding was of marked heterogeneity in all aspects of fMRI. Most programs use multiple tasks, with a fifth routinely using 2, 3, …

Background Consensus panels regularly recommend aerobic exercise for its health-promoting properties, due in part to presumed anti-inflammatory effects, but many studies show no such effect, possibly related to study differences in participants, interventions, inflammatory markers, and statistical approaches. This variability makes an unequivocal determination of the anti-inflammatory effects of aerobic training elusive. Methods and Results We conducted a randomized controlled trial of 12 weeks of aerobic exercise training or a wait list control condition followed by 4 weeks of sedentary deconditioning on lipopolysaccharide (0, 0.1, and 1.0 ng/mL)-inducible tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), and on toll-like receptor 4 …

Faculty & Staff Scholarship

Objective: Omega-3 fatty acids, especially alpha-linolenic acid (ALA), which are present in nuts may reduce cardiovascular disease (CVD) risk, by changing vascular inflammation and improving endothelial dysfunction. The objective of the study was to evaluate the acute effects of two different diets, one containing walnuts and the other almonds on endothelial function.

Methods: Twenty-seven overweight volunteers underwent a randomized 2-period, crossover, controlled intervention study. The subjects were given either walnut or almond diets which varied in monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) content. The walnut diet provided 23.1% energy from PUFA and the almond diet provided 7.6% …

An Exploration Into The Psychotic Symptoms Associated With Schizophrenia And Major Depressive Disorder, Kyndester I. Michael-Samaroo

Honors Undergraduate Theses

This research focuses on examining the neurological similarities between schizophrenia and major depressive disorder with psychotic features in order to compare the manifestations of psychosis in each disorder. Both disorders often involve symptoms of psychosis, although the overall disorders are very different from each other. The hypothesis for this research is that the neurological similarities between schizophrenia and major depressive disorder with psychotic features will provide researchers with the strategies needed to develop a treatment for psychotic symptoms. In order to test this hypothesis, five related studies were gathered for each disorder, and three studies were gathered for psychosis. These …

Training Neurodegenerative Disease Support Group Leaders: A New Support Group Functioning Scale, Therese V. Cash, Christopher Kilbourn, Sarah K. Lageman

Neurology Publications

Support group leaders play pivotal roles in maintaining healthy community support groups; however, these leaders also have personal support needs and typically lack formal training in managing complex behaviors of neurodegenerative disorders. A support group well-being questionnaire, assessing support group functioning, was developed and piloted among participants of an educational training program designed for support group leaders of various neurodegenerative disorder-specific support groups. An exploratory factor analysis evaluated the questionnaire’s psychometric properties and identified a reliable single factor five-item solution, which was titled the Support Group Functioning Scale (SGFS). Preliminary interpretation guidelines were proposed. Development of this scale is a …

A Gut Feeling: A Hypothesis Of The Role Of The Microbiome In Attention-Deficit/Hyperactivity Disorders., Xue Ming, Neil Chen, Carly Ray, Gretchen Brewer, Jeffrey Kornitzer, Robert A Steer

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Attention-deficit/hyperactivity disorder (ADHD) is a neurologic disorder characterized by hyperactivity/impulsivity and/or inattentiveness, with genetic and environmental factors contributing to the disorder. With the growing recognition of the microbiome's role in many neurological disorders, the authors propose that it may also be implicated in ADHD. Here, we describe several evolving areas of research to support this hypothesis. First, a unique composition of gut bacteria has been identified and linked to behaviors in ADHD. Second, our research found an increased incidence of 2 gastrointestinal symptoms (constipation and flatulence) in children with ADHD, as compared to controls. Finally, emerging data may be interpreted …

Over the past years, there have been initiatives to facilitate the process of international study set-up, but the fruits of these deliberations require time to be operationally in place. FOR-DMD (Finding the Optimum Steroid Regimen for Duchenne Muscular Dystrophy) is an academic-led clinical trial which aims to find the optimum steroid regimen for Duchenne muscular dystrophy, funded by the National Institutes of Health (NIH) …

Prognostic Value Of 1p/19q Chromosomal Codeletion In Patients With Oligodendroglioma, Altaf Ali Laghari, Muhammad Usman Khalid, Namra Qadeer, Muhammad Shahzad Shamim

Section of Neurosurgery

Oligodendrogliomas are common intra-axial primary brain tumours, and carry special significance due to several key features, which when present provide better prognosis compared to other intra-axial tumours. One of these features is presence of 1p/19q chromosomal codeletion that seems to not only be a marker of better prognosis but also signifies better response to chemotherapy. Herein the authors review the literature for evidence of the prognostic value of 1p/19q codeletion in OD.

Conclusion: Seizure onset laterality and spread vary with glucose and time …

The Prevalence And Awareness Of Sleep Apnea In Patients Suffering Chronic Pain: An Assessment Using The Stop-Bang Sleep Apnea Questionnaire., Gregory S Tentindo, Scott M Fishman, Chin-Shang Li, Qinlu Wang, Steven D Brass

Articles, Abstracts, and Reports

Purpose: Some patient subsets are at higher risk of sleep apnea, including patients with chronic pain. However, it is unclear whether patients and their caregivers are aware of the possibly increased risk of sleep apnea in this population. Chronic pain is often treated with opioids which may decrease both the central respiratory drive and the patency of the upper airway, potentially contributing to this sleep disorder. Using a self-reporting questionnaire approach in the chronic pain population, this study surveyed patient and caregiver awareness surrounding the risk of sleep apnea. In addition, we looked at the influence of opioid therapy on …

Assessing Cognitive Abilities In High-Performing Cochlear Implant Users., Jake Hillyer, Elizabeth Elkins, Chantel Hazlewood, Stacey D Watson, Julie G Arenberg, Alexandra Parbery-Clark

Articles, Abstracts, and Reports

Despite being considered one of the most successful neural prostheses, cochlear implants (CIs) provide recipients with a wide range of speech perception performance. While some CI users can understand speech in the absence of visual cues, other recipients exhibit more limited speech perception. Cognitive skills have been documented as a contributor to complex auditory processing, such as language understanding; however, there are no normative data for existing standardized clinical tests assessing cognitive abilities in CI users. Here, we assess the impact of modality of presentation (i.e., auditory-visual versus visual) for the administration of working memory tests in high-performing CI users …

Myxopapillary Ependymoma With Anaplastic Features: A Case Report With Review Of The Literature., Tridu R Huynh, Conrad Lu, Doniel Drazin, Gregory Lekovic

Articles, Abstracts, and Reports

Background: Myxopapillary ependymoma (MPE) with anaplastic features is extremely rare, with only three case reports in the literature.

Case Description: We report the case of a MPE with anaplastic features in a 24-year-old female who presented with a dominant lumbar mass along with intracranial and sacral metastases. Upon gross total resection of the dominant tumor located at L2-L3, it appeared to arise from the filum terminale, and had a solid component in addition to soft or necrotic areas. Histologically, the tumor was composed of the two classic components of MPE: (1) low-grade ependymal cells surrounding blood vessels, producing the papillary …

Pilot Data On Responsive Epilepsy Neurostimulation, Measures Of Sleep Apnea And Continuous Glucose Measurements., Katie M Kinnear, Nicole M Warner, Anand Gersappe, Michael J Doherty

Articles, Abstracts, and Reports

Objectives: To match responsive neurostimulator (RNS) and polysomnographic data to determine if RNS detections and stimulations correlate with measurements of sleep disordered breathing and continuous glucose measurements (CGM).

Materials and methods: In a patient with an RNS with detection/stimulation leads implanted bi-temporally detection-stimulation counts were matched by time with coinciding polysomnogram and CGM data.

Results: Temporal dispersion of RNS DSC were independent of measures of sleep apnea, hypopnea or glucose.

Conclusion: Hippocampal nighttime responsive neurostimulation therapies did not appear to worsen measures of normal or abnormal sleep.

Patient Perceived Changes In Sexual Dysfunction After Initiation Of Natalizumab For Multiple Sclerosis, Derrick Robertson, Angela Aungst, Ryan Collier, Jhulianna Vivar, Natalie Moreo, Lise Casady, Tuan Vu

Neurology Faculty Publications

Purpose Sexual dysfunction is a common but often overlooked secondary symptom of multiple sclerosis (MS) and can be associated with a decreased health-related quality of life (HRQoL). Natalizumab is a disease-modifying therapy approved for the treatment of relapsing forms of MS. In addition to its efficacy, those using natalizumab have shown improvement in HRQoL parameters, including fatigue and cognition. The idea that improvement in fatigue may also correlate with improvement in sexual dysfunction is the impetus for this study.

Methods A single-center, open-label, single-arm, 24-week study was performed to evaluate perceived change in sexual dysfunction in MS patients treated with …

Chlamydia Pneumoniae: An Etiologic Agent For Late-Onset Dementia, Brian J. Balin Phd, Christine Hammond, Christopher S. Little, Susan Hingley, Zein Al-Atrache, Denah Appelt, Judith A Whittum-Hudson, Alan P Hudson

PCOM Scholarly Works

The disease known as late-onset Alzheimer's disease is a neurodegenerative condition recognized as the single most common form of senile dementia. The condition is sporadic and has been attributed to neuronal damage and loss, both of which have been linked to the accumulation of protein deposits in the brain. Significant progress has been made over the past two decades regarding our overall understanding of the apparently pathogenic entities that arise in the affected brain, both for early-onset disease, which constitutes approximately 5% of all cases, as well as late-onset disease, which constitutes the remainder of cases. Observable neuropathology includes: neurofibrillary …
