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 …

Examining The Differences In Functional Outcomes For Patients With Traumatic Brain Injury After Acute Rehabilitation And Subacute Rehabilitation: A Review Of The Literature, Michael Rangel, Dr. Ashley Kakkanatt

Rowan-Virtua Research Day

BACKGROUND/PURPOSE

Traumatic brain injury (TBI) is one of the major causes of morbidity in the US [1-4]. Studies suggest TBI patients’ enrollment in a rehabilitation program strongly predicts social reintegration. The structure and outcomes of inpatient rehabilitation programs, including acute and subacute rehabilitation, are not well-delineated [5-7].

DESIGN

A structured review of current literature was conducted. Articles were screened using the search string: (post-traumatic brain injury OR post-TBI OR traumatic brain injury OR TBI) AND (acute rehabilitation OR subacute rehabilitation) AND (outcomes OR functional outcomes) NOT (outpatient OR outpatient populations) NOT (pediatric OR pediatric populations). Articles were limited to 1990 …

Physiological Response And Tissue Damage Following Different Depths Of Impact In A Rodent Model Of Mild Traumatic Brain Injury, Haven K. Predale, Christopher P. Knapp, Barry D. Waterhouse, Rachel L. Navarra

Mild traumatic brain injury (mTBI) is a serious public health concern that can result in significant neurological and behavioral deficit. mTBI results from impact to the head and can be repetitive in nature, especially in sports and domestic violence cases. Our laboratory studies the effects of repetitive mTBI on risky choice behavior in rodents using a closed-head controlled cortical impact (CH-CCI) model of injury and a well-established probabilistic discounting task that assesses risk-based decision-making behavior. We have recently found that females, but not males, display transient increases in risky choice behavior following three CH-CI’s delivered at 5.5m/s velocity and 2.5 …
