Active clinical trials for "Brain Injuries"

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).

The purpose of this protocol is to enable access to intravenous infusions of banked autologous (a person's own) or sibling umbilical cord blood (CB) for children with various brain disorders. This is an expanded access protocol intended for patients who are unable to participate in a clinical trial involving their own or their sibling's cord blood. Children with cerebral palsy, congenital hydrocephalus, apraxia, stroke, hypoxic brain injury and related conditions will be eligible if they have normal immune function and do not qualify for, have previously participated in, or are unable to participate in an active cell therapy clinical trial at Duke Medicine. For the purpose of this protocol the term children refers to patients less than 26 years of age. The cord blood is thawed and then administered as an intravenous infusion. Recipients do not receive chemotherapy or immunosuppression. The mechanism of action is through paracrine signaling of cord blood monocytes inducing endogenous cells to repair existing damage.

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.

Brain injured patients are at high risk of pain due to the illness itself and a variety of nociceptive procedures in intensive care unit. Since the disorder of consciousness, speech, and movement, it is usually difficult for them to self-report the presence of pain reliably. The Critical-Care Pain observation Tool (CPOT) has been recommended for clinical use in the critically ill patients when self-report pain is unavailable. Besides, it seems that the bispectral index (BIS), a quantified electroencephalogram instrument, can be used for pain assessment along with the CPOT tool in some nonverbal critical ill patients (e.g., intubated and deep sedation). However, the validity and reliability of CPOT and BIS for pain assessment in brain injured patients are still uncertain so far. So the aim of this research is to investigate the value of CPOT and BIS for pain evaluation in this specific patient group.

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 investigate the role of cognitive reserve in change in connectivity in the brain (measured with functional magnetic resonance imaging, fMRI) and how this is related to symptoms and symptom resolution.

Traumatic brain injury (TBI) is a leading cause of post-injury hospitalization, disability, and death worldwide. In Nova Scotia, approximately 50% of major trauma reported is head trauma. TBI is predicted to be the most common and expensive neurological condition in Canada through the year 2031. Families and medical teams must often decide on the appropriate level of care for patients with severe TBI and frequently need to consider withdrawal of life support measures. These decisions have implications for patients with severe TBI, costs to the health care system, and rates of organ donation. A reliable method for neurological evaluation at the time of the patient's arrival to the hospital is important, because it is possible that many patients with severe TBI already have permanent brain damage. Assessing this brain damage with clinical tests is difficult because of the nature of patients' injuries and the sedative medication they receive at the time of their hospital admission. Current standard imaging technique for these patients is severely limited in the assessment of the extent and severity of the brain damage. Advanced diagnostic imaging, called Computed Tomography Perfusion (CTP), can help detect permanent brain damage. However, CTP of the head is not currently done for patients with severe TBI when they arrive at the hospital. The investigators want to test whether CTP of the head can detect permanent brain damage among patients with severe TBI.

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.
