Department of Neurosurgery Posters

Introduction

Isometheptene is thought to be the active ingredient of the commonly known headache medication, Midrin. Previously, we found only the (R) enantiomer to be effective in alleviating headache behavior in two models of headache compared to the (S) enantiomer.

Experiments using electrical and mechanical stimulation of the dura in animals with no history of head pain have been used to elucidate the mechanisms of the trigeminovascular system at the level of the trigeminal ganglion, trigeminal nucleus caudalis, periaqueductal gray, and the thalamus. The limitation of these acute models is that electrical and mechanical stimulation of the dural blood vessels …

1st Place Research Paper: The Effectiveness Of Yoga Therapy On An Adult, Post-Stroke Population: A Systematic Review, Baylor E. Hogan

Kevin and Tam Ross Undergraduate Research Prize

Objectives: The objectives of this paper are to (1) give a brief overview of stroke pathophysiology (2) outline yoga as a therapeutic strategy (3) present the current research on yoga rehabilitation for stroke (4) discuss the efficacy of yoga for chronic stroke.

Methods: Relevant terms were searched in PubMed, Web of Science, Academic OneFile, ScienceDirect, and Google Scholar electronic databases. Studies were excluded if they contained pediatric stroke, non-stroke neurological diseases, or subjects with comorbidities. Statistically significant data was extracted for the primary measures of nine trials.

Results: Four studies measured statistically significant outcomes (p<0.05). These included improvements in balance, independence, endurance, trait anxiety, fear of falling, self-efficacy, pain, strength, range of motion (ROM), activity, participation, and quality of life (QoL). Discussion: Lack of statistical significance in post-stroke depression (PSD) measures may be due to inadequate intervention length or a psychosocial cause of depression. Improvements in balance, flexibility, and strength from yoga participation permitted progress in disability and functionality. Finally, overall health-related quality of life (HRQL) is affected by the severity of mental disorders and physical disability. Yoga can have a positive effect in both domains and therefore, may improve HRQL.

Paired Associative Transspinal And Transcortical Stimulation Produces Bidirectional Plasticity Of Human Cortical And Spinal Motor Pathways, Luke Dixon, Mohamed Ibrahim, Danielle Santora

Dissertations, Theses, and Capstone Projects

Anatomical, physiological, and functional connectivity exists between primary motor cortex (M1) and spinal cord neurons. Paired associative stimulation (PAS) produces enduring changes in M1 based on the Hebbian principle of associative plasticity. The present study aims to discover immediate neurophysiological changes on human corticomotor pathways by pairing noninvasive transspinal and transcortical stimulation via transcranial magnetic stimulation (TMS). We delivered paired transspinal and transcortical stimulation for 40-min at precise interstimulus intervals with TMS being delivered after (transspinal-transcortical PAS) or before (transcortical-transspinal PAS) transspinal stimulation. Transspinal-transcortical PAS markedly decreased intracortical inhibition, increased intracortical facilitation and M1 excitability with concomitant decreases of motor …

Preventing Stroke At Door Step– Need For A Paradigm Shift In Delivery Of Preventive Healthcare, Ismail A. Khatri, Saad Farooq, Muneeza A. Khatri

Pakistan Journal of Neurological Sciences (PJNS)

Although stroke is a preventable disease, it is increasing globally. Only few risk factors are responsible for much of the leading noncommunicable diseases, yet those remain poorly controlled, despite being the most affordable way of promoting health and preventing disease [1]. Lifestyle modification including cessation of smoking, making aerobic physical activity a routine, certain changes in diet, and aggressive management of risk factors are all part of stroke prevention strategies [2].

Changes In The Adult Glun2b Associated Proteome Following Adolescent Intermittent Ethanol Exposure, H. Scott Swartzwelder, Mary-Louise Risher, Kelsey M. Miller, Roger J. Colban, Danner G. Winder, Tiffany A. Wills

Biomedical Sciences

Adolescent alcohol use is the strongest predictor for alcohol use disorders. In rodents, adolescents have distinct responses to acute ethanol, and prolonged alcohol exposure during adolescence can maintain these phenotypes into adulthood. One brain region that is particularly sensitive to the effects of both acute and chronic ethanol exposure is the hippocampus. Adolescent intermittent ethanol exposure (AIE) produces long lasting changes in hippocampal synaptic plasticity and dendritic morphology, as well as in the susceptibility to acute ethanol-induced spatial memory impairment. Given the pattern of changes in hippocampal structure and function, one potential target for these effects is the ethanol sensitive …

Revealing The Quality Of Movement: A Meta-Analysis Review To Quantify The Thresholds To Pathological Variability During Standing And Walking, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Neuromotor processes are inherently noisy, which results in variability during movement and fluctu-ations in motor control. Although controversial, low levels of variability are traditionally considered healthy, while increased levels are thought to be pathological. This systematic review and meta-analysisof the literature investigates the thresholds between healthy and pathological task variability.

After examining 13,195 publications, 109 studies were included. Results from over 3000 healthy sub-jects and 2775 patients revealed an overall positive effect size of pathology on variability of 0.59 forwalking and 0.80 for sway. For the coefficient of variation of stride time (ST) and sway area (SA), upperthresholds of 2.6% …

Plasma Neuronal Exosomal Levels Of Alzheimer's Disease Biomarkers In Normal Aging, Erin L. Abner, Gregory A. Jicha, Leslie M. Shaw, John Q. Trojanowski, Edward J. Goetzl

Sanders-Brown Center on Aging Faculty Publications

Plasma neuronal exosomal levels of pathogenic Alzheimer's disease (AD) proteins, cellular survival factors, and lysosomal proteins distinguish AD patients from control subjects, but changes in these exosomal proteins associated with normal aging have not been described for cognitively intact subjects. Plasma neuronal exosomal levels of P-T181-tau, P-S396-tau, Aβ_1-42, cathepsin D, repressor element 1-silencing transcription factor, and neurogranin were quantified longitudinally in cognitively intact older adults using two samples collected at 3- to 11-year intervals. Except for P-S396-tau, exosomal protein levels changed significantly with aging, but were largely outside the range observed in AD patients.

Alzheimer’s disease (AD) is characterized by two molecular pathologies: cerebral β-amyloidosis in the form of β-amyloid (Aβ) plaques and tauopathy in the form of neurofibrillary tangles, neuritic plaques, and neuropil threads. Until recently, only Aβ could be studied in humans using positron emission tomography (PET) imaging owing to a lack of tau PET imaging agents. Clinical pathological studies have linked tau pathology closely to the onset and progression of cognitive symptoms in patients with AD. We report PET imaging of tau and Aβ in a cohort of cognitively normal older adults and those with mild AD. Multivariate analyses identified unique …
