Critically Appraised Paper For “Effects Of Dance On Motor Functions, Cognitive Functions, And Mental Symptoms Of Parkinson’S Disease: A Quasi-Randomized Pilot Trial”, May Anne Gamueda, Caroline Lee, Susan Nguyen, Ajay Pala, Blanka Pentek, Kitsum Li

Occupational Therapy | Critically Appraised Papers Series

Parkinson’s disease (PD) is a systemic condition that presents not only motor but also nonmotor symptoms, as a result of dopamine deficiency in the basal ganglia. Rehabilitation typically focuses on motor deficits, however, despite the fact that nonmotor symptoms have a significant impact on quality of life. The researchers of this study investigated the effectiveness of dance on motor functions, cognitive functions, and mental symptoms of individuals with PD. They chose dance as their intervention because it has been shown to activate the basal ganglia as well as improve mood. In addition to motor function and mood, the researchers also …

Neural Correlates Of Taste Reactivity In Autism Spectrum Disorder., Jason A Avery, John E Ingeholm, Sophie Wohltjen, Meghan Collins, Cameron D Riddell, Stephen J Gotts, Lauren Kenworthy, Gregory L Wallace, W Kyle Simmons, Alex Martin

Psychiatry and Behavioral Sciences Faculty Publications

Selective or 'picky' eating habits are common among those with autism spectrum disorder (ASD). These behaviors are often related to aberrant sensory experience in individuals with ASD, including heightened reactivity to food taste and texture. However, very little is known about the neural mechanisms that underlie taste reactivity in ASD. In the present study, food-related neural responses were evaluated in 21 young adult and adolescent males diagnosed with ASD without intellectual disability, and 21 typically-developing (TD) controls. Taste reactivity was assessed using the Adolescent/Adult Sensory Profile, a clinical self-report measure. Functional magnetic resonance imaging was used to evaluate hemodynamic responses …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Up to 90% of individuals with Huntington's disease (HD)-a progressive, inherited neurodegenerative disorder-experience apathy. Apathy is particularly debilitating because it is marked by a reduction in goal-directed behaviors, including self-care, social interactions, and mobility. The objective of this study was to examine relationships between variables of apathy, functional status, physical function, cognitive function, behavioral status/emotional function, and health-related quality of life. Clinician-rated measures of physical, cognitive, and behavioral function, including one clinician-rated item on apathy, and self-reported measures of physical function, health-related quality of life, and emotional, cognitive, and social function were collected in a single session from 487 persons …

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 …

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 …

Investigating The Role Of The Gut Microbiome In Huntington Disease, Casey G. Hart

Honors Undergraduate Theses

Huntington disease (HD) is an inherited neurodegenerative disease caused by a trinucleotide repeat expansion in the huntingtin (HTT) gene. Metabolic dysfunction is a feature of HD that is recapitulated in HD mouse models. Our lab has shown that circadian feeding rhythms are disrupted in humanized HD mice and restored by suppression of brain HTT. Furthermore, when circadian feeding rhythm is artificially restored, in addition to normalization of metabolic function, liver and striatal HTT is temporarily reduced, demonstrating that HTT is involved in gut-brain feedback. The gut microbiome, which can regulate gut-brain feedback, has been implicated in the pathogenesis …

Insulin-Like Growth Factor-1 Overexpression Mediates Hippocampal Remodeling And Plasticity Following Tbi, Erica Latrice Littlejohn

Theses and Dissertations--Physiology

Every year over 2.5 million traumatic brain injuries (TBI) occur and are the leading cause of death and disability among adolescents. There are no approved treatments for TBI. Survivors suffer from persistent cognitive impairment due to posttraumatic tissue damage and disruption of neural networks which significantly detract from their quality of life. Posttraumatic cognitive impairment depends in part on the brain's limited ability to repair or replace damaged cells. Immature neurons in the hippocampus dentate gyrus, a brain region required for learning and memory, are particularly vulnerable to TBI. Insulin-like growth factor-1 (IGF1) is a potential therapeutic for TBI because …

Posters

BACKGROUND

Approximately 10% of school age children suffer from migraines, making migraines one of the top five health problems experienced by youth today

School nurses often are the first healthcare provider seen by youth with migraine; visits to the school nurse for headaches amounted to one-third of the enrolled student population in a large local school district. (see reference)

Empowering school nurses through education and resources to identify and manage migraines therefore may have significant benefits to children with migraines and their families.

OBJECTIVE

To improve migraine care in the community through establishing a headache specialist mentorship program for select …

Cellular Senescence Is Induced By The Environmental Neurotoxin Paraquat And Contributes To Neuropathology Linked To Parkinson’S Disease, Shankar J. Chinta, Georgia Woods, Marco Demaria, Anand Rane, Ying Zou, Amanda Mcquade, David T. Madden

Faculty Publications & Research of the TUC College of Pharmacy

Exposure to the herbicide paraquat (PQ) is associated with an increased risk of idiopathic Parkinson’s disease (PD). Therapies based on PQ’s presumed mechanisms of action have not, however, yielded effective disease therapies. Cellular senescence is an anticancer mechanism that arrests proliferation of replication-competent cells and results in a pro-inflammatory senescence-associated secretory phenotype (SASP) capable of damaging neighboring tissues. Here, we demonstrate that senescent cell markers are preferentially present within astrocytes in PD brain tissues. Additionally, PQ was found to induce astrocytic senescence and an SASP in vitro and in vivo, and senescent cell depletion in the latter protects against …

Elevated L-Lactate Drives Major Cellular Pathologies Associated With Neurodegeneration, Jessica Behnke

Dissertations, Master's Theses and Master's Reports

Within the past few decades, lactate research has expanded from initial findings deeming lactate as a dead-end metabolic product to recognition of lactate’s role as a potential energy substrate in the CNS. Due to the tight relationship between lactate and energy metabolism, interest in the scientific community has been mounting around associations among metabolic dysregulation, elevated lactate and neurodegenerative states such as Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis, ischemia/reperfusion (AD, PD, ALS, I/R injuries), and physiological aging, however underlying cellular mechanisms and/or facilitators for neuronal degeneration pathologies still remain unknown. Here, we tested several hypotheses that implicate L-lactate to various neurodegenerative …

Ccl11 As A Biomarker For The In Vivo Diagnosis Of Chronic Traumatic Encephalopathy, Robert Weissenfels

CMC Senior Theses

Chronic traumatic encephalopathy is the neurodegenerative disease that is ascribed to the long term development of cognitive, behavioral, emotional, and motor deficits as a result of the exposure to high amounts of sub concussive traumatic brain injuries. The disease has gained recent popularity in the media for its prevalence in American football as a response to recent research that has suggested the prominence of the disease in nearly every NFL player that is examined post mortem. This has produced a growing concern for the consequences of head impact and participation in contact sports. Despite media attention, little is currently known …

The Utility Of Multidisciplinary Rehabilitation As A Treatment Strategy For Circadian Rhythm And Sleep Disturbances In Premanifest Huntington’S Disease, Danielle Megan Bartlett

Theses: Doctorates and Masters

Background: Huntington’s disease (HD) is a rare, neurodegenerative disease caused by an expanded cytosine-adenine-guanine (CAG) sequence in the Huntingtin gene, resulting in the production of an aberrant protein, mutant huntingtin (mHTT). The mHTT protein exhibits a toxic loss and gain in function, leading to degeneration of neurons in the brain. Consequently, the classic triad of motor, cognitive and mood features of the disease develop. Among the earliest features of HD are circadian rhythm and sleep disturbances. These anomalies present many years prior to formal clinical diagnosis of HD and, while it has been postulated that these disturbances arise as a …

Mathematics and Statistics Faculty Publications and Presentations

Recent studies have found an association between functional variants in TREM2 and PLD3 and Alzheimer's disease (AD), but their effect on cognitive function is unknown. We examined the effect of these variants on cognitive function in 1449 participants from the Wisconsin Registry for Alzheimer's Prevention, a longitudinal study of initially asymptomatic adults, aged 36–73 years at baseline, enriched for a parental history of AD. A comprehensive cognitive test battery was performed at up to 5 visits. A factor analysis resulted in 6 cognitive factors that were standardized into z scores (∼N [0, 1]); the mean of these z scores was …

Understanding Huntington's Disease Using Machine Learning Approaches, Sonali Lokhande

KGI Theses and Dissertations

Huntington’s disease (HD) is a debilitating neurodegenerative disorder with a complex pathophysiology. Despite extensive studies to study the disease, the sequence of events through which mutant Huntingtin (mHtt) protein executes its action still remains elusive. The phenotype of HD is an outcome of numerous processes initiated by the mHtt protein along with other proteins that act as either suppressors or enhancers of the effects of mHtt protein and PolyQ aggregates. Utilizing an integrative systems biology approach, I construct and analyze a Huntington’s disease integrome using human orthologs of protein interactors of wild type and mHtt protein. Analysis of this integrome …

Novel Therapeutic Approaches For Juvenile Neuronal Ceroid Lipofuscinosis (Cln3), Megan Elizabeth Bosch

Theses & Dissertations

Juvenile Neuronal Ceroid Lipofuscinosis (JNCL) is a lysosomal storage disease caused by autosomal recessive mutations in CLN3. Neuronal loss is thought to occur via glutamate excitotoxicity; however, little is known about neuron-astrocyte glutamate regulation in JNCL. We discovered that Cln3^Δex7/8 astrocytes have significantly lower basal spontaneous Ca²⁺ oscillations and decreased responses to glutamate, indicating a disrupted signaling network. Cln3^Δex7/8 astrocytes also displayed significantly lower basal mitochondrial respiration and ATP production, suggesting impaired metabolic functions. Concurrent with diminished astrocyte metabolism and Ca²⁺ signaling, Cln3^Δex7/8 neurons were hyper-responsive to glutamate stimulation. These studies suggest that CLN3 …

Evaluation Of Immune-Modulating Therapies For Parkinson's Disease, Katherine E. Olson

Theses & Dissertations

Parkinson’s disease (PD) is the second most common neurodegenerative

disorder, second only to Alzheimer’s disease (AD). It is characterized by a

progressive loss of dopaminergic neurons along the nigrostriatal axis and the

formation of proteinaceous inclusions of alpha-synuclein (α-syn). Secondary to

the loss of dopaminergic neurons is a progression in motor and non-motor

symptoms. Motor symptoms are characterized by slowness in movement,

stiffness and tremor. Non-motor symptoms include depression, constipation,

sleep abnormalities and loss of sense of smell. The cause of disease remains

incompletely understood. However, age, genetics, environment, viral infection,

and interplay between the innate and adaptive immune system …
