Mild Traumatic brain injury (mTBI) is a signature wound in military personnel, and repetitive mTBI has been linked to age-related neurogenerative disorders that affect white matter (WM) in the brain. However, findings of injury to specific WM tracts have been variable and inconsistent. This may be due to the heterogeneity of mechanisms, etiology, and comorbid disorders related to mTBI. Non-negative matrix factorization (NMF) is a data-driven approach that detects covarying patterns (components) within high-dimensional data. We applied NMF to diffusion imaging data from military Veterans with and without a self-reported TBI history. NMF identified 12 independent components derived from fractional …

Background: There is growing awareness and clinical interest in athletes with affective symptoms after sport-related concussion (SRC), as these symptoms may contribute to overall symptoms and represent a modifiable risk factor of longer recovery. However, evidence of their effects on the entire return-to-play (RTP) trajectory, particularly among women and men, is limited.
Purpose/Hypothesis: To examine the relationship between affective symptom reporting and RTP progression after SRC among a cohort of Division 1 student-athletes. We hypothesized that those endorsing affective symptoms, specifically nervous-anxious symptoms, spend more time in RTP progression and recovery.
Study Design: Cohort study; Level of evidence, 3.
Methods: …
Repeated Low-Level Blast Induces Chronic Neuroinflammation And Neurobehavioral Changes In Rat Models, Arun Reddy Ravula
Repeated Low-Level Blast Induces Chronic Neuroinflammation And Neurobehavioral Changes In Rat Models, Arun Reddy Ravula
Dissertations
Blast-induced neurotrauma (bTBI) is a signature medical concern for military personnel when they are exposed to explosions in active combat zones. However, soldiers as well as law enforcement personnel are also repeatedly exposed to low-level blasts during training sessions with heavy weaponries as part of combat readiness. Service personnel who sustain brain injuries from repeated low-level blasts (rLLBs) do not display overt pathological symptoms immediately but rather develop cognitive impairments, attention deficits, anxiety, and sleep disturbances over time. An improved rat model of rLLB was developed in this thesis by applying controlled low-level blast pressures (10 psi) repeated five times …
A Meta-Analysis On The Differences In Neuroplasticity Between Women And Men After Traumatic Brain Injuries, Victoria A. Martin
A Meta-Analysis On The Differences In Neuroplasticity Between Women And Men After Traumatic Brain Injuries, Victoria A. Martin
Honors Theses
The current meta-analysis investigates the differences in neuroplasticity between women and men after a traumatic brain injury (TBI). Research on the differences in neuroplasticity between women and men is relatively new and few studies have reported outcome variables by gender after TBIs. Neuroplasticity is the brain’s ability to adapt and change particularly because of learning or brain injuries. TBI is a leading cause of death and disability worldwide; because of this, learning more about these differences can give scientists and clinicians more information on how to better treat people with brain injuries. Current research is inconsistent on whether there is …
The Injury-Induced Neurogenic Response And The Role Of Notch1 In Regulating This Process, Nicole M. Weston
The Injury-Induced Neurogenic Response And The Role Of Notch1 In Regulating This Process, Nicole M. Weston
Theses and Dissertations
Traumatic Brain Injury (TBI) is a prevalent problem with an estimated 5 million people suffering from chronic cognitive impairments long after the injury. Following TBI there is a series of pathophysiological changes in the brain including neurogenesis, an important response linking endogenous repair and regeneration. The dentate gyrus (DG) of the hippocampus is a primary neurogenic region within the adult brain where neural stem and progenitor cells (NS/NPCs) reside. Studies using rodent models have shown that cognitive recovery after TBI is associated with new neurons generated from the DG. Thus far, in studies examining post-injury neurogenesis, the regulatory mechanisms, functional …
