Concussion Awareness And Educational Outreach Through A Website And Mobile Application, Daniel J. Brogan

Neuroscience Summer Fellows

In recent years concussions have become a more apparent problem in youth and adolescent sports. 1 in 5 high school students will sustain a concussion during the season. Due to medical and scientific advances, the diagnosis of concussions is becoming much simpler with key markers that are signs for an injury. Returning to play too soon before an athlete is fully recovered increases the likelihood that serious and irreversible neurological deficits can occur. Symptoms for concussions are necessary to track in order for an athlete to properly report their recovery to a physician. Doctors primarily rely on a patient’s report …

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. …

A Systematic Approach In Treating Post Concussion Syndrome, Donna Susan Freeborn, Ryan S. Francis

Student Works

Concussions and their associated symptoms are a growing health concern. The CDC reported in 2010 over 2.5 million people visited an emergency room for treatment of concussions and associated injuries: a 70% increase over the past decade.1 As the incidence of concussions continues to grow, Nurse Practitioners (NP) will be involved in the management of their follow-up care. Correctly managing these concussed patients is extremely important because a concussion can cause “... impairment affecting an individual’s memory, behavior, learning, and/or emotions. Appropriate diagnosis, management, and education are critical for helping these patients recover quickly and fully .” 2 The purpose …

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 …

Coaching And Concussions: Prevention, Education, And Perspective, Colby J. Felts

Honors Thesis

The large participation of players and coaches in football has made it one of the most popular sports in America. Concussions have specifically gained national attention in football due to frequent, high impact collisions. A concussion injury poses a unique threat in high school football because of the developing adolescent brain and high participation numbers. Additionally, lack of medical personnel to diagnose concussions at the high school level imposes a legal duty on the coaches. The thesis develops a recommended plan of action for directors of Iowa high school football to assist in preserving the future of the sport. A …

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 …

Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen

Open Access Theses & Dissertations

Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …

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 …
