Active clinical trials for "Brain Concussion"

Using the Blink Reflexometer, athletes are scanned if they are potentially thought to have a concussion during a game or practice.

The iDETECT (Integrated Display Enhanced Testing for Concussion and mild traumatic brain injury) system is a novel portable, open access platform that enables immediate and rapid assessment of multimodal neurologic function. This study seeks to evaluate the iDETECT function testing battery with currently used balance and inner ear assessment methods during initial concussion clinic referral. Two groups of participants will be enrolled; a concussion related dizziness cohort and control subjects. The investigators will enroll the concussion cohort from patients presenting to the Sports Concussion Institute (SCI) with persistent dizziness and imbalance symptoms following possible concussion. Healthy control participants will be recruited from the local community. iDETECT's ability to identify post concussion balance/vestibular disturbances will be compared to an expert concussion assessment. Both cohorts will participate in the iDETECT assessment and the clinical assessment.

The purpose of this pilot project is to determine whether using inertial sensors placed on the waist during routine clinical balance testing (i.e. Balance Error Scoring System) (BESS), will be a more immediate, objective, reliable and sensitive way to measure and quantify balance deficits in individuals with mild Traumatic Brain Injury (mTBI). The investigators are also trying to observe if the sensors can be used to detect balance recovery after a mTBI. The investigators hypothesis is that collegiate atheltes with mTBI injury will have different recovery periods between their cognitive testing(IMPACT) and their balance measures.

Patients with traumatic brain injury are likely to present with cognitive, psychological, emotional and behavioral problems during different periods, all of which affect patients' life quality seriously. The aim of this study was to assess cognitive and psychosocial outcome in patients with mild traumatic brain injury, and to determine the risk factors associated with cognitive and psychological outcome. Mini-mental state examination (MMSE), activities of daily living scale (ADL), the Hospital Anxiety Depression Scale (HADS) and mental health symptom checklist (SCL-90) were used to assess the cognitive performance and psychological outcomes in 360 patients with mild traumatic brain injury. Chi-square, Fisher's exact tests and Logistic regression analysis were used to analyze the risk factors.

Mild traumatic brain injury (mTBI) accounts for 70-90% of all diagnosed traumatic brain injuries (TBI) affecting approximately 50-300 per 100.000 individuals annually. Persistent post-concussion symptoms are reported in 15-80% of hospital admitted and outpatient treated populations, affecting labour market attachment, academic achievement, income, socio-economic status, social interactions, home management, leisure activities and cohabitation status. The association between mTBI and long-term trends in cohabitation status, income, academic achievement and socio-economic status has not been thoroughly explored. Previous studies focus on children's academic performance after severe TBI and only few studies include early adulthood and patients with mTBI. Trends in divorce rates are frequently conducted on severe injuries or populations consisting of veterans. Additionally, all studies have failed to apply a national register based design. Aim The aim of the study is to examine the long-term associations between mTBI and trends in cohabitation status, academic achievement and socio-economic status between pre-injury rates and observed rates at 5 years post-injury. The hypothesis was that by 5 years mTBI would be associated with increased odds of marital breakdown, decreasing academic achievement, decreasing income, decreasing socio-economic status compared to the general population in Denmark. Methods: The study is a national register based cohort study with 5 years follow-up of patients with mild traumatic brain injury from 2008 - 2012 in Denmark. Population: Patients between 18-60 years diagnosed with concussion (ICD-10 S06.0) were extracted from the Danish National Patient Register between (2003-2007). Patients with major neurological injuries and previous concussions at the index date and 5 years before the index date (1998-2007) were excluded. Patients who were not resident in Denmark 5 years before and during the inclusion period were also excluded (1998-2007). Data will be retrieved from several national databases, including: the Danish national patient register, Danish Civil Registration System (CRS), the Danish Education Registers, the Income Statistics Register and the Employment Classification Module (AKM). One control of the general population were matched for each case on sex, age and municipality. Outcome measures are: Cohabitation status, Education, income and socio-economic status.

Perhaps no issue in sports medicine has attracted so much media attention and academic interest in recent years as the potential long-term neurodegenerative sequelae of sports-related concussion on athlete's brain health. Rugby has a high incidence of concussion. Recent research findings from a cohort of former professional players found that the number of concussions sustained during their professional careers was associated with the rate of diagnosed clinical depression and late-life cognitive impairment. A limitation of these studies is the use of a self-reported history of concussion. The reliability of professional rugby players to recall and self-report concussion history has never been quantified in the literature to date. Imperfect recall can generate bias in epidemiologic studies when the proportion of events recalled is associated with the health end points of interest. Associations observed may be spurious and due to recall bias if athletes differ in their knowledge and recognition of concussion symptomology in a manner that is associated with the health outcome of interest ie. under/overreporting of concussion. It is difficult to estimate the magnitude of the bias in the absence of any "gold-standard" measure of concussion history. Due to these concerns about the quality of self-reported concussion history, the investigators considered that it was important to evaluate the reliability of self-reported concussion history.

mTBI is widely recognized as a major public health concern in the United States and worldwide. mTBI diagnosis remains a clinical challenge as no single test can diagnose every concussion. Recent advances in EEG evoked response potential analysis have led to a novel technique for assessing brain network activation (BNA) patterns. This study purpose is to study this BNA technology in individuals who have sustained a concussion.

The purpose of this study is to determine the sensitivity and specificity of an aid in assessment of concussion based on eye-tracking, in comparison to a clinical reference standard appropriate for the Emergency Department (ED) or concussion clinic.

Traumatic brain injury (TBI) is defined as a structural alteration of brain function caused by external causes, where mild traumatic brain injury (mTBI) represents approximately 80% of all TBI, and although its prognosis is relatively good, it represents a significant cost to the system due to the need to perform a cranial computed tomography (CT) scan, a test of high economic value and not without risks such as irradiation, especially important and dangerous in the pediatric age. The investigators aim to set-up a point of-care (POC) device to validate a biomarker (H-FABP) able to diagnose the presence of brain damage in children and adults with mTBI at trauma and paediatric Emergency Departments using a blood sample, in order to save resources and avoid subjecting patients to a potentially damaging imaging test. But also, to assess whether the incorporation of new biomarkers improves the prediction of brain damage that can be done with H-FABP. For that, the investigators will recruit a 400 patients' cohort with blood samples using the available POC device for H-FABP biomarker.

The study aims: to observe a population particularly exposed by the past to brain trauma and concussion: Motorsport Pilots who are retired from a professional practice of motor sport; to report results of their neuro-cognitive evaluations, to determine if specific profiles emerge. to evaluate potential consequences of these traumas' history at a cerebral, physical and psychological level. to evaluate the contribution of the various examinations performed as part of a concussion assessment in routine care (eye-tracking, brain imaging, Neuropsychological Assessment).
