Community Awareness Of Youth Sport Related Concussion: A Neuropsychological Perspective, Ryan D. Bennett, Claire Stafford, Shanna K. Williams, Vijay Bajnath, Chris Burley, Alison Datoc, Alexis Hartman

Journal for Sports Neuroscience

There continues to be growing public awareness regarding concussions and the detrimental effects sustaining such an injury can have on one’s life. Of increased importance is the understanding of how concussions impact children and adolescents, particularly as a result of sport engagements. Contact sports involving youth account for 41% of the concussions seen in emergency departments (Waltzman et al., 2020). Of note, hospital estimates tend to underrepresent the total number of sport-related concussions as they do not factor patients treated in a community setting (Bazarian et al., 2020). In consideration of this public health epidemic, there is a current projection …

Brain and Mind Institute Researchers' Publications

Acute brain changes are expected after concussion, yet there is growing evidence of persistent abnormalities well beyond clinical recovery and clearance to return to play. Multiparametric MRI is a powerful approach to non-invasively study structure-function relationships in the brain, however it remains challenging to interpret the complex and heterogeneous cascade of brain changes that manifest after concussion. Emerging conjunctive, data-driven analysis approaches like linked independent component analysis can integrate structural and functional imaging data to produce linked components that describe the shared inter-subject variance across images. These linked components not only offer the potential of a more comprehensive understanding of …

The Effect Of Napping On Sleep Quality And Quantity In Healthy And Concussed Collegiate Athletes, Katie Stephenson-Brown

Graduate Theses and Dissertations

Clinicians are increasingly prescribing a regulated sleep schedule to athletes post injury; however, baseline sleep habits of collegiate athletes are unknown. Moreover, the connection between napping and sleep quality and quantity has not been studied in collegiate athletes. Therefore, the purpose of this study is to investigate napping behaviors and their effects on sleep quantity and quality in concussed and non-concussed collegiate athletes. In a sample of 233 non-concussed collegiate athletes, 74% (172/233) of participants reported napping. Napping was not significantly associated with sleep quantity (χ 2 (2) = .23, p = .64) or quality (χ 2 (1) = .42, …


Physical Therapy Review Of Best Practices Based On Psychology, Bethany Painter May 2018

Physical Therapy Review Of Best Practices Based On Psychology, Bethany Painter

Honors Projects

Physical therapy is a field that is growing and changing constantly. For so long, it was assumed that physical healing should be the sole focus of physical therapy. While this is an important aspect of the rehabilitation process, there is so much more to it than that. The psychological trauma a person may experience following an injury can be just as challenging, if not more challenging to overcome than the physical repercussions of the injury. For this reason, it is important to take psychological healing into consideration, as well as physical healing when creating best practices for physical therapists. The …

Restoration Of Attentional Deficits After Concussion, Katharine B. Earle

Cal Poly Humboldt theses and projects

Difficulties with concentration and attention are among the most prevalent symptoms experienced after concussion. Rest has been the most common form of recovery from concussion; however, new research is suggesting mild mental exertion to be an effective aid in recovery. Drawing from Attention Restoration Theory, this study evaluated the idea that cognitive engagement with natural environments can mitigate post-concussion directed-attention deficits. A between subjects repeated measures design was used to test directed-attention after video exposure to restorative/nature and nonrestorative/city environments. Measures of mood, connectedness to environment, and symptomology scores were also collected. No meaningful difference between exposure type was found …

Assessing Clinical Significance Of The Immediate Post-Concussion Assessment And Cognitive Testing Battery When Comparing Adjusted And Unadjusted Rci Methods For Different Ranges Of Baseline Scores, Ashley N. Figaro May 2016

Assessing Clinical Significance Of The Immediate Post-Concussion Assessment And Cognitive Testing Battery When Comparing Adjusted And Unadjusted Rci Methods For Different Ranges Of Baseline Scores, Ashley N. Figaro

UNLV Theses, Dissertations, Professional Papers, and Capstones

The growing concern revolving around the dangers of sports-related concussions have led to the most recent implementation of neurocognitive (NC) test batteries as a means to objectively determine the presence of a cognitive defect. Whereas any other sports-related injury can be diagnosed with tools such as an x-ray or MRI, a concussion represents a metabolic disturbance that cannot be identified by these diagnostic tools. Many neurocognitive test batteries employ statistical techniques to derive cut off scores in order to represent significant or insignificant changes as compared to individual baseline scores, or pre-established normative values. If an individuals’ post-injury score exceeds …


A Culture That Fosters Concussions: Does Increased Education Lead To More Accurate Reporting Of Concussions?, Michael Heptig Jan 2016

A Culture That Fosters Concussions: Does Increased Education Lead To More Accurate Reporting Of Concussions?, Michael Heptig

PCOM Psychology Dissertations

With over 1.7 million incidents reported annually, concussion has become the most common class of traumatic brain injury (TBI) in the United States (Bazarian, Zhu, Blyth, Borrino, & Zhong, 2012). As staggering a statistic as this may be, many believe it fails to represent the true number of concussions because the non-reporting of symptoms has been commonplace among athletes (Khurana & Kaye, 2012; Williamson & Goodman, 2006). The aim of this study was to determine those factors that influence the reporting of concussion symptoms. Specific variables that were examined include the amount of concussion education provided (determined by requisite amount …

The current study analyzed data from Division I collegiate athletes who completed Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) baseline assessments at four sequential time points that varied over the course of their athletic careers. Administrations were part of a larger National Institutes of Health (NIH) study. Growth curve modeling showed that the two memory composite scores increased significantly with successive administrations: Change in Verbal Memory was best represented …


Impaired Executive Function In Concussed Athletes, Marisa Gretz Jul 2015

Impaired Executive Function In Concussed Athletes, Marisa Gretz

Neuroscience Summer Fellows

Concussions are classified as mild traumatic brain injuries (mTBI). An individual that has sustained a concussion will experience symptoms such as nausea, possible memory loss, blurry vision, or loss of balance. Most symptoms subside within a few days, but a large pool of research raises concern for the recovery of executive function, specifically impulse control. Executive function relates to all tasks that require deliberate attention. Past research has shown adolescents record the highest number of sports concussions when compared to collegiate and professional athletes. The frontal lobe, which controls executive function, is not fully developed during the time of adolescence. …


Pathological Effects Of Repeated Concussive Tbi In Mouse Models: Periventricular Damage And Ventriculomegaly, Richard H. Wolferz Jr. May 2015

Pathological Effects Of Repeated Concussive Tbi In Mouse Models: Periventricular Damage And Ventriculomegaly, Richard H. Wolferz Jr.

Honors Scholar Theses

Repeated concussive traumatic brain injury (rcTBI) is the most prominent form of head injury affecting the brain, with an estimated 1.7 million Americans affected each year (Kuhn 2012). Neurologists have been concerned about the danger of repeated head impacts since the 1920’s, but researchers have only begun to understand the long-term effects of rcTBI (McKee 2009). Although symptoms can be as mild as dizziness, current research suggests that multiple concussions can lead to a progressive degenerative brain disease known as chronic traumatic encephalopathy (CTE) (Luo 2008, McKee 2009, Kane 2013). Research on the brain is just beginning to scratch the …


Ohio Athletic Trainer's Reactions To New Ohio Concussion Legislation, Alexander K. Heaton Apr 2015

Ohio Athletic Trainer's Reactions To New Ohio Concussion Legislation, Alexander K. Heaton

The Research and Scholarship Symposium (2013-2019)

This research examines the effects that concussion legislation has had on how Certified Athletic Trainers practice medicine in the state of Ohio. In the spring of 2009, the state of Washington passed a bill that would change how concussions are handled in youth sports. According to the legislation, all athletes who display any signs and symptoms of a concussion are to be removed immediately from play and are not able to return to play until cleared by a licensed professional health care provider. Since then, concussion legislation of some form has been passed in every state, with Ohio passing its …


Neurocognitive Patterns, Symptom Clusters, And Premorbid Factors That Predict Protracted Recovery From Concussion In Females, Sarah Pulaski Jan 2015

Neurocognitive Patterns, Symptom Clusters, And Premorbid Factors That Predict Protracted Recovery From Concussion In Females, Sarah Pulaski

PCOM Psychology Dissertations

Concussion is an increasingly diagnosed injury that affects individuals of all ages. Although the underlying cause is unknown, research has demonstrated that females who sustain a concussion experience longer recoveries. Existing research has documented a relationship between age, gender, post-concussive headache and mental health conditions, and recovery; however, limited research has investigated the relationship between premorbid clinical variables and recovery. Research on post-injury neurocognitive declines and recovery has also demonstrated varied findings. Moreover, dizziness has been identified as significantly predictive of prolonged recovery, but no studies have investigated the effect of premorbid headache conditions on the development of dizziness. The …

Department of Psychology: Faculty Publications

The purpose of this study was to quantify head impact exposure (frequency, location and magnitude of head impacts) for individual male and female collegiate ice hockey players and to investigate differences in exposure by sex, player position, session type, and team. Ninety-nine (41 male, 58 female) players were enrolled and 37,411 impacts were recorded over three seasons. Frequency of impacts varied significantly by sex (males: 287 per season, females: 170, p < 0.001) and helmet impact location (p < 0.001) but not by player position (p = 0.088). Head impact frequency also varied by session type; both male and female players sustained more impacts in games than in practices (p < 0.001), however the magnitude of impacts did not differ between session types. There was no difference in 95th percentile peak linear acceleration between sexes (males: 41.6 g, females: 40.8 g), but 95th percentile peak rotational acceleration and HITsp (a composite severity measure) were greater for males than females (4424, 3409 rad/s2, and 25.6, 22.3, respectively). Impacts to the back of the helmet resulted in the greatest 95th percentile peak linear accelerations for males (45.2 g) and females (50.4 g), while impacts to the side and back of the head were associated with the greatest 95th percentile peak rotational accelerations (males: 4719, 4256 rad/sec2, females: 3567, 3784 rad/sec2, respectively). It has been proposed that reducing an individual’s head impact exposure is a practical approach for reducing the risk of …
