Investigating Synergistic Effects Of Mild Traumatic Brain Injury And Reduced Cholinergic Tone On Attentional Deficits And Alzheimer's-Like Pathology In Haβ And Htau Mice, Elizabeth M. Teasell

Electronic Thesis and Dissertation Repository

Mild traumatic brain injury (mTBI) increases the risk of Alzheimer’s disease. The early cholinergic decline in Alzheimer’s disease and cholinergic damage observed after TBI suggest a distinct role of this neural system in vulnerability to Alzheimer’s disease following TBI. This thesis evaluated the role of repetitive mTBI and cholinergic dysfunction in the development of cognitive deficits, specifically attentional deficits, and Alzheimer’s-related pathology in mice expressing humanized amyloid-beta and tau and a vesicular acetylcholine transporter knockdown to induce a mild cholinergic deficit. Using the rodent continuous performance test, it was shown that repetitive mTBI in the presence of an already vulnerable …

OBJECTIVE

The purpose of this study was to assess the potential barriers to sports physical therapy and athletic training clinicians implementing graded exertional tests, specifically for their patients following concussion.

Neurocognitive Performance Differences Between Athletes Who Are Deaf Or Hard-Of-Hearing And Athletes Who Are Hearing, Matthew P. Brancaleone, Jaclyn Caccese, James Onate

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE

There are over 71,000 college students in the United States who are deaf or hard-of-hearing (D/HoH), with many participating in athletics. Athletes who are D/HoH have similar concussion rates to athletes who are hearing at the collegiate level. Differences in neurocognitive baseline performance between athletes who are D/HoH and athletes who are hearing may exist due to misunderstanding of written English instructions or differences in sensory processing. Therefore, the purpose of this study was to compare neurocognitive performance between athletes who are hearing and athletes who are D/HoH.

Interactions Between Repetitive Mild Traumatic Brain Injury And Methylphenidate Administration On Catecholamine Transporter Protein Levels Within The Rodent Prefrontal Cortex, Anna Abrimian, Eleni Papadopoulos, Christopher P. Knapp, J. Loweth, Barry Waterhouse, Rachel Navarra

Rowan-Virtua Research Day

It is theorized that low concentrations of dopamine (DA) and norepinephrine (NE) within in the prefrontal cortex (PFC) following traumatic brain injury (TBI) leads to increased risky behavior. Our lab has shown that repeated mild TBI (rmTBI) sex-differentially increases risky behavior in a rodent model. Methylphenidate (MPH) is a psychostimulant drug used to treat symptoms of Attention-Deficit Hyperactivity Disorder (ADHD), also driven by a hypo-catecholaminergic PFC. MPH elevates catecholamine levels by blocking DA and NE transporters, DAT and NET. While the potential of psychostimulants to treat post-TBI symptoms have been explored, the effects of sub-chronic MPH on transporter levels following …
