Active clinical trials for "Brain Injuries, Traumatic"

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.

The aim of this research is to determine if the biological fluids (blood/saliva) from chronic brain-injured patients (both blast and non-penetrating TBI) contain reproducible protein markers. To accomplish this two populations of chronic TBI patients who are receiving treatment at The Institute for Research and Rehabilitation (TIRR): blast injury victims and non-penetrating TBI will be studied. Using multiple proteomic approaches including mass spectrometry, multiplex ELISAs, and antibody microarrays, as well as RNA profiling, the investigators aim to identify biomarkers in the blood/saliva of patients suffering from chronic TBI and to determine the similarities/differences between the blast and non-penetrating injury groups. Identification of these biochemical changes will give insight into the long-lasting changes associated with head injury, and may identify new targets for treating the associated pathologies.

PBA is a neurologic condition that is estimated to impact over a million patients and their families in the United States. PBA occurs secondary to an otherwise unrelated neurologic disease or injury, and manifests as involuntary, frequent, and disruptive outbursts of crying and/or laughing. Progress has been made in better understanding this debilitating condition, but much more needs to be done. That's why a new PBA patient registry, PRISM (Pseudobulbar Affect RegIstry Series), has been initiated. The goal of PRISM is to establish the prevalence and quality of life (QOL) impact of PBA in patients with underlying neurologic conditions including Alzheimer's disease Amyotrophic lateral sclerosis Multiple sclerosis Parkinson's disease Stroke Traumatic brain injury Because this is an observational registry, it doesn't require you to intervene with any specific treatment or procedure. Your participation allows the PRISM registry to collect and analyze data from your site and also compare it to national numbers captured in the PRISM registry about PBA across all of the major at-risk neurologic populations.

Patients with mild to moderate traumatic brain injury (TBI) are at risk for secondary neurological deterioration. Their outcome within the first week after injury could be predicted by clinical signs, brain CT scan and transcranial doppler (TCD) on admission to the emergency room. The investigators aim to evaluate the diagnostic performance of TCD to screen patients presented with mild to moderate TBI and mild lesions on CT scan, i.e., Trauma Coma Data Bank, TCDB classification II. The principal outcome measure is the negative predictive value of TCD.

This study will test a method of measuring brain blood flow called near infrared spectroscopy (NIRS). It will determine whether NIRS gives the same results as the more commonly used technique, functional magnetic resonance imaging (fMRI). Healthy normal volunteers between 18 and 60 years of age may be eligible for this study. Participants come to the NIH up to six times for experiments using NIRS and fMRI. They do the following tasks while they are undergoing NIRS or fMRI: looking at a computer monitor while a checkerboard pattern changes wiggling the toes and moving the fingers Reading words on a computer screen and pushing one button if they are plants and another if they are animals. For NIRS, a frame is placed on the head and held it in place with a metal band. The frame holds sensors that contact the scalp. For fMRI, the subject lies on a table that can slide in and out of an MRI scanner, a metal cylinder surrounded by a strong magnetic field. fMRI uses a strong magnetic field and radio waves to obtain images of the brain while the subject performs tasks. During the procedure, The subject wears earplugs to muffle the sound of loud knocking noises that occur during scanning.

The investigators evaluated whether it was possible to improve the measurement of memory, attention, and executive function in patients who have suffered traumatic brain injury through the use of computer-based testing. Note: the original design of the study was altered due to failure to recruit sufficient numbers of patients who were willing to undergo prolonged cognitive training.

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.

This study evaluates the impact of platelet transfusion on geriatric patients with platelet dysfunction from Traumatic Brain Injury. The authors hypothesize that patients will recover better if their platelet dysfunction is corrected with platelet transfusion.

A systolic blood pressure (SBP) lower than the heart rate (HR) could indicate a poor condition in trauma patients. In such scenarios, the reversed shock index (RSI) is <1, as calculated by the SBP divided by the HR. This study aimed to clarify whether RSI could be used to identify high-risk adult patients with isolated traumatic brain injury (TBI).

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.
