Central alexia is a common reading disorder caused by stroke. Patients with central alexia (CA) are slow to read and make frequent errors, and have additional problems with their spoken language. This study has 3 aims: 1. Investigating the neural networks that support reading in patients with CA Despite being a relatively common syndrome, there have been no functional brain imaging studies of CA. This project will use magnetic resonance imaging (MRI) and magnetoencephalography (MEG) to understand which brain regions are damaged and whether preserved parts of the reading network can be encouraged by therapy to support reading recovery. 2. Testing a new treatment for CA The research team has developed training software called 'iReadMore', which uses a crossmodal approach (written words paired with spoken words) to train reading. This therapy has been shown to be effective in patients with a similar form of reading disorder called pure alexia. The iReadMore software will be adapted to address the reading deficit in CA, and the research will test whether it significantly improves reading ability. 3. Using brain stimulation to enhance behavioural training Transcranial direct current stimulation (tDCS) is a brain stimulation technique that has been shown to improve language performance in healthy controls and stroke patients. This study will test whether tDCS (delivered simultaneously with the 'iReadMore' therapy) significantly enhances reading rehabilitation. Patients will be split into two groups: one will receive a 4 week block of training plus real tDCS first, followed by a 4 week block of training plus sham tDCS; the other group will receive the two therapy blocks in the opposite order. Both groups will ultimately receive the same amount of behavioural therapy and tDCS stimulation. Comparing the reading improvement over the real and sham tDCS blocks will demonstrate whether tDCS enhances the behavioural improvements in reading ability. Hypothesis: iReadMore reading therapy will significantly improve single word reading speed in patients with central alexia. tDCS brain stimulation will significantly enhance the effect of iReadMore therapy, compared to sham stimulation.
This investigation addresses emotional health in community dwelling persons with traumatic brain injury (TBI). It is designed to test the efficacy of a novel behavioral treatment for depression and anxiety symptoms. This treatment incorporates principles of Behavioral Activation (BA), a promising treatment model for depression and anxiety after TBI, and implementation intentions, a theoretically motivated method to enhance enactment of goal-relevant behaviors via action planning. To maximize the impact of this intervention over time, we use the low-cost, widely available technology of SMS, or text messaging, to promote positive behavior change in accordance with planned values and intentions. Participants are randomized 1:2:2 to one of three conditions. Condition 1: a control condition in which participants receive SMS messages with self-selected motivational statements. Condition 2: a condition using BA-based implementation intentions. Condition 3: a condition using BA-based activity monitoring and scheduling based on personal values.
The purpose of this study is to assess the feasibility of exenatide infusion for the treatment of high blood sugars following acute brain injury.
This project addresses the rehabilitation and mental health needs of married combat Veterans post-deployed from Iraq or Afghanistan with a mild traumatic brain injury (mTBI) and/or significant posttraumatic stress (PTS) or combat-related stress (CS) by providing psychoeducation, communication and problem solving skills in a multifamily group (MFG) setting. In this group, Veterans and spouses/cohabiting partners learn customized therapeutic strategies to help compensate for deficits and promote Veteran community integration, interpersonal and emotion regulation skills, and marital satisfaction. The effectiveness of the skills-based MFG will be compared to that of a health education group which offers a supportive environment and basic education without skills training through a randomized clinical trial. As there is currently no family-based intervention for Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans with mTBI offered within the VA spectrum of services, this intervention fills a crucial gap in healthcare for our newest Veterans.
This is a descriptive retrospective study designed to measure the efficacy of remifentanil sedation and the ability to perform frequent neurological examinations of patients with traumatic brain injuries.
Subarachnoidal hemorrhage (SAH) is a cause of long-term disability and death. Annually about 1000 people in Finland suffer from SAH, their average age being under 50 years. SAH has a mortality rate of 12 % acutely and 40 % of patients die within a month from admission to hospital. In addition, 30 % of the surviving patients remain with neurological deficits. Most survivors of the primary insult suffer from secondary injury during the first 2-3 weeks from the insult. Despite the advances in neurosurgical and -radiological techniques and intensive care, the mortality and morbidity rates in SAH have not changed in recent years. There is still only limited understanding of the mechanisms of secondary insults causing brain injury after SAH. In this study the investigators are aiming to clarify the timescale and mechanisms contributing to the secondary insults. The investigators also explore usability of novel biomarkers to guide treatment of the patients suffering from SAH.
The purpose of this study is to examine the safety and efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with Amantadine relative to rTMS Alone and Amantadine Alone for persons in chronic states of seriously impaired consciousness. The hypothesis is that provision of rTMS+Amantadine will provide a safe yet synergistic effect that induces or accelerates functional recovery.
Adult patients, age ≥ 18 years, with clinically diagnosed mild, moderate or severe brain trauma will be asked to participate in the study. This prospective database will consist of 400 subjects with TBI, 200 from both TUCH and Cambridge Addenbrooke's Hospital. In addition, 100 controls will be recruited, with 50 from both centres.This study is a prospective clinical observational study with detailed data collecting. All patients will be treated according to the accepted, standardized, existing guidelines that are based on national and international recommendations. New treatment interventions will NOT be evaluated during the data acquisition for this study.
The purpose of this research study is to investigate the effectiveness of a technique designed to improve processing speed (i.e. the amount of time it takes to process information) in a Traumatic Brain Injury (TBI) population. The study is designed to study how well this technique can help people with TBI increase their processing speed and their ability to function better in everyday life.
