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 ...

Department of Neurosurgery Posters

Background & Objectives

Headache is a common symptom of post-concussion syndrome which may persist in a substantial portion of patients contributing to a poor quality of life and disability. There is a pressing need to develop novel treatments for post-traumatic headache as current treatments have a number of side effects, are contraindicated or lack efficacy. The Elliott laboratory first established models of post-traumatic headache demonstrating sensitization of trigeminal neurons in rodent models of post-traumatic headache using well-known nociceptive and behavioral markers in the pain and migraine fields1-3. Traumatic brain injury in mice increases expression of calcitonin gene related peptide (CGRP ...

Methods: A quantitative meta-analysis was performed on three separate studies, each of which evaluated the efficacy and safety outcomes of a direct factor Xa inhibitor versus warfarin in preventing stroke in patients with atrial fibrillation. The direct factor Xa inhibitors that were evaluated included apixaban, edoxaban, and rivaroxaban. Results: The direct factor Xa inhibitors were found to be as effective, and in some cases more effective, than warfarin in preventing ...


Encoding Of Saltatory Tactile Velocity In The Adult Orofacial Somatosensory System, Rebecca Custead 2016 University of Nebraska-Lincoln

Encoding Of Saltatory Tactile Velocity In The Adult Orofacial Somatosensory System, Rebecca Custead

Public Access Theses and Dissertations from the College of Education and Human Sciences

Processing dynamic tactile inputs is a key function of somatosensory systems. Spatial velocity encoding mechanisms by the nervous system are important for skilled movement production and may play a role in recovery of motor function following neurological insult. Little is known about tactile velocity encoding in trigeminal networks associated with mechanosensory inputs to the face, or the consequences of movement.

High resolution functional magnetic resonance imaging (fMRI) was used to investigate the neural substrates of velocity encoding in the human orofacial somatosensory system during unilateral saltatory pneumotactile inputs to perioral hairy skin in 20 healthy adults. A custom multichannel, scalable ...

Neurology Faculty Publications

Background

ADHD is the most common neuropsychiatric condition affecting individuals of all ages. Long-term outcomes of affected individuals and association with severe comorbidities as SUD or conduct disorders are the main concern. Genetic associations have been extensively described. Multiple studies show that intronic variants harbored in the ADGRL3 (LPHN3) gene are associated with ADHD, especially associated with poor outcomes.

Methods

In this study, we evaluated this association in the Multimodal Treatment Study of children with ADHD (MTA), initiated as a 14-month randomized clinical trial of 579 children diagnosed with DSM-IV ADHD-Combined Type (ADHD-C), that transitioned to a 16-year prospective observational ...

BACKGOUND: The purpose of this study was to assess the biological and clinical effects of n-acetyl-cysteine (NAC) in Parkinson's disease (PD).

METHODS: The overarching goal of this pilot study was to generate additional data about potentially protective properties of NAC in PD, using an in vitro and in vivo approach. In preparation for the clinical study we performed a cell tissue culture study with human embryonic stem cell (hESC)-derived midbrain dopamine (mDA) neurons that were treated with rotenone as a model for PD. The primary outcome in the cell tissue cultures was the number of cells that survived ...

Phase Iii Preclinical Trials In Translational Stroke Research: Community Response On Framework And Guidelines, Johannes Boltze, Daniel-Christoph Wagner, Nils Henninger, Nikolaus Plesnila, Cenk Ayata

Neurology Publications and Presentations

The multicenter phase III preclinical trial concept is currently discussed to enhance the predictive value of preclinical stroke research. After public announcement, we collected a community feedback on the concept with emphasis on potential design features and guidelines by an anonymous survey. Response analysis was conducted after plausibility checks by applying qualitative and quantitative measures. Most respondents supported the concept, including the implementation of a centralized steering committee. Based on received feedback, we suggest careful, stepwise implementation and to leave selected competencies and endpoint analysis at the discretion of participating centers. Strict application of quality assurance methods is accepted, but ...

1st Place: The Effectiveness Of Yoga Therapy On An Adult, Post-Stroke Population: A Systematic Review (Final Research Paper), 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.

Conclusion: Preliminary evidence suggests the ...

Brain Structure In Pediatric Tourette Syndrome, Alton C. Williams, Kevin J. Black

Kevin J. Black, MD

Previous studies of brain structure in Tourette syndrome (TS) have produced mixed results, and most had modest sample sizes. In the present multi-center study, we used structural MRI to compare 103 children and adolescents with TS to a well-matched group of 103 children without tics. We applied voxel-based morphometry methods to test gray matter (GM) and white matter (WM) volume differences between diagnostic groups, accounting for MRI scanner and sequence, age, sex and total GM + WM volume. The TS group demonstrated greater GM volume in posterior thalamus, hypothalamus and midbrain, and lower WM volume bilaterally in orbital and medial prefrontal ...

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 ...

Radiology Faculty Publications

Xp21.2 duplication syndrome is a rare genetic disorder of undetermined prevalence and clinical relevance. As the use of chromosomal microarray has become first line for the work-up of childhood developmental delay, more gene deletions and duplications have been recognized. To the best of our knowledge, the imaging findings of Xp21.2 duplication syndrome have not been reported. We report a case of a 33 month-old male referred for developmental delay that was found to have an Xp21.2 duplication containing IL1RAPL1 and multiple midline brain malformations.


Improving Ventricular Catheter Design Through Computational Fluid Dynamics, Sofy Hefets Weisenberg 2016 University of Tennessee - Knoxville

Improving Ventricular Catheter Design Through Computational Fluid Dynamics, Sofy Hefets Weisenberg

Masters Theses

Cerebrospinal fluid (CSF) shunts are fully implantable medical devices that are used to treat patients suffering from conditions characterized by elevated intracranial pressure, such as hydrocephalus. In cases of shunt failure or malfunction, patients are often required to endure one or more revision surgeries to replace all or part of the shunt. One of the primary causes of CSF shunt failure is obstruction of the ventricular catheter, a component of the shunt system implanted directly into the brain's ventricular system. This work aims to improve the design of ventricular catheters in order to reduce the incidence of catheter obstruction ...

Department of Neurology Faculty Papers

Temporal lobe epilepsy (TLE) affects multiple brain regions through evidence from both structural (gray matter; GM) and functional connectivity (FC) studies. We tested whether these structural abnormalities were associated with FC abnormalities, and assessed the ability of these measures to explain episodic memory impairments in this population. A resting-state and T1 sequences were acquired on 94 (45 with mesial temporal pathology) TLE patients and 50 controls, using magnetic resonance imaging (MRI) technique. A voxel-based morphometry analysis was computed to determine the GM volume differences between groups (right, left TLE, controls). Resting-state FC between the abnormal GM volume regions was computed ...

Neuroimaging Of Cerebral Venous Thrombosis, Mohammad Wasay, Muhammad Azeemuddin 2016 Aga Khan University

Neuroimaging Of Cerebral Venous Thrombosis, Mohammad Wasay, Muhammad Azeemuddin

Mohammad Wasay

Early and accurate diagnosis of cerebral venous thrombosis (CVT) is possible with the help of computed tomography (CT) scan and magnetic resonance imaging (MRI). Empty Δ sign on postcontrast CT is present in only up to 30% of the cases. The role of CT venography is not yet established, but it is emerging as an effective modality for diagnosis of CVT. T2* MRI sequence is superior to spin echo in detecting CVT and small hemor rhages. MR venography is considered the technique of choice for diagnosis and follow-up of CVT, but in certain cases, MRI could be superior as it ...
