Active clinical trials for "Brain Concussion"

The investigational device used in this clinical investigation, the Nurochek PRO System (NCPRO), is a portable electroencephalogram (EEG) headset which delivers a visual stimulus and measures a VEP. The visual stimulus is delivered to the subjects' eyes via light-emitting diodes, and the EEG measures the user's visual-evoked potential. This headset communicates with an application on a computer, which processes the signals and transmits them to a secure cloud server for analysis and storage of the data. Nurochek PRO is a development of the previously FDA cleared Nurochek System. The primary objective of this clinical investigation was to evaluate the performance of the investigational device (NCPRO) against clinical diagnosis of detection of mild traumatic brain injury (mTBI). The primary endpoint outlined for this study was set at the collection of 100 valid investigational device readings from individuals with concussion and 500 valid investigational device readings from healthy individuals who have had a plausible mechanism of sustaining a concussion, but do not have one. Additionally, readings from healthy individuals are also to be acquired. The aim of this study was to collect data from 100 readings from individuals with concussion. The initial assumption was that sites would provide players pre-season and make players available for testing post-concussion. In practice, some sites provided player data only post-concussion event (such as medical clinics). Participants were acquired from sporting clubs, medical clinicals and schools.

The purpose of this study is to determine the value of including dynamic vision testing into California State University, Northridge (CSUN) Athletics' established concussion protocol. The study's hypotheses are 1) dynamic vision testing will reveal vision impairments right after a person sustains a concussion, 2) these impairments may still be present upon clearance to return to play.

Rugby is a popular contact sport in France the majority of whom are amateur players. Concussion is one of the main risks given its potential severity and frequency (between 2.78 and 10 per 1,000 player hours). Faced with a concussion, stop sport activity, medical evaluation and a progressive resumption of activity are simple things to do to avoid an over-risk of injury and better recovery of the player. For this purpose, the rugby federation implement the blue card and the concussion declaration by clubs. A recent study showed that the directives of the federation are not sufficiently respected. The non-declaration problem is added knowing that around 50% of concussions are not declared. In professional rugby, the presence of a medical staff makes possible to optimize care as much as possible. In the amateur world, there are not always medical or paramedical personnel trained for this problem at the edge of the field when all the participants (player, coach, coaching) lack of knowledge on the subject and that the general practicer remains the referent for the concussion management. We will reach a dozen amateur rugby club to complete a questionnaire about concussions and conduct un formation session about this issue.

This is a research study that aims to examine whether Veterans with mild Traumatic Brain Injuries are at risk for dementia by studying their memory, brain wave activity, brain structure and proteins that can be elevated after brain injury and in dementia.

The purpose of the study is to validate the clinical outcome in patients with closed head injuries (GCS 14-15, ages 18-85) who are being evaluated for head trauma, integrating the BrainScope One structural injury classifier (SIC) algorithm, with focus on SIC negative classification. In addition, to assess functional impairment (concussion) in these patients, results from Brain Function Index (BFI) or Concussion Index (CI) algorithms will be used for analysis.

This study is looking at the specific role of an exercise prescription on recovery from concussion symptoms in the general population.

Approximately 150,000 children present each year to emergency departments (EDs) in the US with concussion and many more are treated by primary care physician, or outpatient specialists. Concussion is defined as a traumatically induced transient disturbance of brain function and involves a complex pathophysiological process. There is a variety of symptoms related to concussion, and the diagnosis of concussion requires the use of symptom-checklist. Since there is a various degree of the severity of those symptoms, the diagnosis is a subjective one and lacks sensitivity. One major problem is that approximately one-third of the children with concussion experience ongoing somatic, cognitive, and psychological or behavioral symptoms, referred to as persistent post-concussion symptoms. A recent study that investigated the validity a 12-point PPCS risk score revealed that it had modest validity (0.71). Moreover, one of the greatest concerns is the child's schedule return to activity. Since the basic mechanism for concussion is acceleration/ deceleration movement of axons, it is likely to be expressed in desynchronization of delta wave activity between anterior hemispheres as seen in pathological problems related to attention and/ or working memory). The aim of this proof-of-concept study is to find-out whether interhemispheric desynchronization of delta waves (IHDD) in the anterior hemispheres can identify acute concussion in children. If the investigators find that IHDD can accurately diagnose acute concussion, a second objective will be to examine whether this index can be a useful tool in the follow up of patients with persistent post-concussion symptoms.

The purpose of this study is to identify changes in salivary ribosomal nucleic acid (RNA) expression that are predictive of symptom duration and character following mild traumatic brain injury (mTBI) in children.

This study will evaluate a combination of a novel Dual-task regime together with other already known tests in terms of defining when an athlete is ready to return to play after a concussion.

The investigators aim to use a repeated measures observational study utilising a battery of multimodal assessment tools (symptom, cognitive, visual, motor). The investigators aim to recruit 200 rugby players (male and female) from University Rugby Union teams and local amateur rugby clubs in the North East of England. The multimodal battery assessment used in this study will compare metrics between digital methods and against traditional assessment.
