Active clinical trials for "Brain Injuries"

This is a prospective, interventional study aiming to assess the effectiveness of the Esophageal Cooling Device (ECD) as a temperature control modality in post cardiac arrest patients. In addition, observed adverse events during ECD use, ease-of-use, nurse satisfaction and patient outcomes will be examined.

Traumatic brain injury (TBI) is the most common cause of death and disability in young adults. Patients can experience significant problems with concentration, attention, and memory (so called 'cognitive impairments') following TBI. These cognitive impairments can drastically impact on a patient's well-being, and can lead to significant economic and social consequences. Roughly a quarter of TBI patients improve but an equal number deteriorate over time. The investigators know little about why patients vary so much in how they recover. Crucially, the investigators have no treatments to improve brain functioning or recovery after TBI. Trials investigating ways of protecting the brain just after injury have been disappointing. An alternative strategy, however, is to improve the function of brain regions that remain intact, but that function inefficiently after TBI. The investigators know that dopamine (a chemical in the brain) is known to influence many brain functions and the investigators know that pathways in the brain that use dopamine are affected by TBI. In humans, drugs that increase dopamine in the brain, such as methylphenidate, are sometimes used to enhance cognitive function after TBI, but the response to treatment can be highly variable between patients. Therefore, what is needed in the clinic is a way to target the use of these drugs to patients who are likely to respond. In a single centre study, the investigators will use SPECT (Single Photon Emission Tomography) imaging to measure dopamine levels in the brain. MRI (Magnetic Resonance Imaging) scans will assess brain structure and function. The investigators will test whether treatment with methylphenidate improves cognitive functions in TBI patients who have ongoing cognitive problems, whether the mechanism involves a normalisation of brain functioning and whether brain dopamine levels can predict the magnitude of any improvement in symptoms.

The present pilot study is designed to assess the extent to which BOTOX and MYOBLOC cause muscle atrophy in spastic patients. The primary objective is to assess whether there is statistically significant difference in muscle atrophy between the two groups over a one year period.

In this study researchers will apply transcranial direct current stimulation (tDCS) for 5 consecutive days in chronic patients in minimally conscious state (MCS). 2 sessions of 5 days of stimulation will be realized, one anodal and one sham. After each stimulation, behavioral improvement will be assessed with the Coma Recovery Scale Revised (CRS-R). A final assessment will be done one week after the end of the sessions to assess the long term effect of the tDCS.

This project will study 40 Veterans identified with symptoms understood to characterize mild to moderate Traumatic Brain Injury (TBI) including Post Traumatic Stress Disorder (PTSD). Following screening and informed consent, Veterans will be randomly assigned to treatment with repetitive Transcranial Magnetic Stimulation (rTMS) or sham rTMS (placebo). Additional examinations will compare brain imaging (structural and functional MRI scans at rest) across participants at baseline, after acute rTMS treatment, and at 6 month followup. The VA population differs significantly from populations that have been included in prior trials of rTMS for many conditions such as depression, chronic pain, and PTSD. Many returning Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) personnel and Veterans with concussion histories report cognitive problems, such as impaired attention, verbal fluency, poor planning, reduced working memory, and mental flexibility. The investigators hope to show the efficacy and durability of rTMS in treating these symptoms safely in Veterans with co-morbidities.

The TOPHR HIT trial is a clinical trial of patients experiencing blunt trauma who present with an injury to their head which makes them unconscios. The study compares two different fluids given to the patient in the out of hospital setting by a paramedic. The two fluids are salt water (standard treatment) versus a higher concentration of salt water mixed with a sugar (study fluid). The patients have an equal chance of receiving either fluid and the paramedic and the patient and the treating trauma surgeon do not know which fluid was provided in the out of hospital setting.

This study will provide initial data on the safety and effectiveness of allopregnanolone in improving neurobehavioral outcome and reducing mortality in adults with moderate and severe traumatic brain injury.

One of the most pressing concerns within the VA currently is the provision of interventions that address the cognitive as well as emotional problems faced by Veterans with concurrent mild TBI and PTSD. One purpose of this study is to learn more about how PTSD and mild brain injury influences how people think, act, and feel. This may include how people pay attention, keep information in memory, organize plans for achieving important goals, and manage stress. Another purpose of this research is to learn more about the effects of cognitive training on the thinking, behavior, and emotions of individuals with PTSD and mild brain injury - both in the short- and long-term. With this research, the investigators hope to better understand and treat cognitive and emotional difficulties that can occur due to PTSD and mild brain injury.

The primary objective of this study is to evaluate the preliminary effectiveness and acceptability of an innovative in-home nonpharmacological intervention, the Veterans' In-home Program (VIP), for Veterans with mild to moderate traumatic brain injury (TBI) and their families. VIP is designed to promote community reintegration, improve quality of life, and support functioning by realigning environmental demands to match the Veteran's abilities.

To evaluate the efficacy of a structured outpatient couples intervention program (Therapeutic Couples Intervention, TCI) on couples' marital quality after acquired brain injury (ABI). To assess the impact of the TCI on the emotional well-being of persons with ABI and their partners. To ascertain the impact of the TCI on caregiver burden and unmet needs as reported by partners of persons with ABI. To examine the extent to which treatment benefits for survivors and their caregiving partners are sustained in the longer-term.
