Filter by:Patients with brain injury secondary to stroke, surgery, or trauma frequently suffer from homonymous hemianopia, defined as vision loss in one hemifield secondary to retro- chiasmal lesion. Classic and effective saccadic compensatory training therapies are current aim to reorganize the control of visual information processing and eye movements or, in other words, to induce or improve oculomotor adaptation to visual field loss. Patients learn to intentionally shift their eyes and, thus, their visual field border, into the area corresponding to their blind visual field. This shift brings the visual information from the blind hemifield into the seeing hemifield for further processing. Patients learn, therefore, to efficiently use their eyes "to keep the 'blind side' in sight". Biofeedback training (BT) is the latest and newest technique for oculomotor control training in cases with low vision when using available modules in the new microperimetry instruments. Studies in the literature highlighted positive benefits from using BT in a variety of central vision loss, nystagmus cases, and others.The purpose of this study is to assess systematically the impact of BT in a series of cases with hemianopia and formulate guidelines for further use of this intervention in vision rehabilitation of hemianopia cases in general.
The proposed study will evaluate a new approach to cognitive rehabilitation of mild traumatic brain injury (mTBI) using a brain stimulation technique called transcranial direct current stimulation (tDCS). Specifically, we will investigate how tDCS combined with cognitive training improves deficits to attention and working memory in Active Duty Service Members with a history of mild traumatic brain injury (TBI). Measures of attention-related brain activity, neurocognitive assessments, and self-reported clinical outcomes will be used to determine effects of tDCS vs. sham tDCS when paired with a cognitive training intervention. By doing this study, we hope to find a reliable, noninvasive, and efficient method of treating mild TBI cognitive symptoms.
Primary aim: The primary aim of the study is to compare survival to discharge (or survival to 14 days post-operatively, whichever comes first) following emergency surgery for traumatic brain injury (TBI) across Human Development Index settings. Primary outcome measure: The primary outcome measure will be survival to discharge (or survival to 14 days post-operatively, whichever comes first) Primary comparison: Between country groups defined by human development index. Centre eligibility: Any hospital or clinic worldwide performing emergency surgery for traumatic brain injury is eligible to participate. Patient eligibility: All adult and paediatric patients admitted to the participating institution with a traumatic brain injury for which they receive emergency surgery during the selected 30-day inclusion period are eligible for inclusion in the study. Team: Individual hospital teams with up to four people, collecting data for 30 days. Time period: Local study teams may select any 30-day period from the 1st of November 2018 and the 31st of December 2019 to start their study. Patients operated on who meet the inclusion criteria between 00:01 on day 0 and 23:59 on day 30 of the selected study period will be included. Validation: We will employ a method of data validation in every centre that will give us a quantitative estimate of case ascertainment that is feasible even in low-resource centres.
Traumatic brain injury (TBI) is a leading cause of death among trauma patients accounting for one-third of all trauma mortalities. Patients who survive the initial trauma are liable to secondary insults from the ensuing inflammatory state in the brain. Treatment goals are aimed at reducing secondary injury. Maintaining adequate brain perfusion, limiting cerebral edema, and optimizing oxygen delivery are part of established treatment protocols. Numerous therapeutics have been evaluated as potential treatment for TBI with very limited success and there is no medication that alters survival. Various novel therapeutic options have been investigated to prevent the secondary brain injury. Remote Ischemic Conditioning (RIC) is one of these therapies. RIC involves decreasing blood flow to a normal tissue usually the arm by inflating the blood pressure cuff 30mmHg over the systolic blood pressure. The decreased blood flow or ischemia is maintained for 5 minutes followed by releasing the pressure and re-perfusion of the arm. This cycle is usually repeated 4 times. RIC has been shown to improve outcomes in patients with heart attacks, strokes, elective neurosurgeries. A prospective observational study and a randomized clinical trial has shown the protective effect of RIC in TBI patients. Additionally, multiple studies in animals have shown that RIC is neuroprotective after TBI. RIC is non-invasive and harmless except for a little discomfort in the arm. The aim of the study is to evaluate the impact of RIC on long term outcomes in patients with TBI.
