The use of new technologies in the rehabilitation environment, has the target to reduce the impact on the disabling conditions. So that, the goal of this investigation is to evaluate the system use effectiveness of the Leap Motion Controller® in the treatment on the upper limb on patients with neurological disease.
Developing Therapies for Traumatic Brain Injury
Traumatic Brain InjuryBackground: - A person who has a traumatic brain injury (TBI) -- also called concussion -- can have serious and long-lasting effects. Doctors who treat TBI need more information about how the brain changes over time in people with TBI and how well a person recovers from it. To make existing TBI treatments more effective and develop new ones, researchers want to look more closely at how TBI affects people both physically and psychologically. Objectives: - To collect medical information from people with recent traumatic brain injury and compare this information to that of healthy volunteers and of persons who have had injuries to other parts of their bodies besides their heads (such as broken bones, orthopedic injuries, after surgery). Eligibility: 3 groups of people between the ages of 18 and 70 years will be asked to take part. Persons who have had a traumatic brain injury (or concussion ) within the past 30 days, OR Persons who are healthy and have never had a traumatic brain injury, OR Persons who have had an injury within the past 30 days to a part of their body other than the head (such as a broken bone, orthopedic injury, surgery) Design: This study requires two outpatient visits each lasting 1 1/2 days. The 2 visits will be about 30 days apart. Persons with TBI and non-TBI injuries must have their first visit within 30 days of their injury. Screening: Participants will be screened with a medical history, physical examination, blood tests and electrocradiogram (ECG a routine heart test). The research will involve: Giving blood samples (no more than 75 ml each visit). Having tests of memory, attention, concentration, and thinking (neuropsychological testing). Having imaging studies of the head including magnetic resonance imaging (MRI) and positron emission tomography (PET) scans. Persons with TBI will have the same tests at Visit 1 and 2. Healthy controls and persons with non-TBI injuries will have the same tests at Visit 1 as listed above. But, at Visit 2, they will not have brain MRIs or PETs. No treatments will be provided as part of this research protocol.
Evaluation of Pediatric Procedural Sedation With Rectal Chloral Hydrate or Intranasal Midazolam...
Traumatic Brain InjuryComputed Tomography1 moreThousands of children receive sedation for diagnostic and therapeutic interventions annually, and this number is expected to increase. Children are at higher risk for sedation-related complications than adults. In different scenarios, multiple drugs are used to achieve sedation, each one with particular adverse events that must be monitored and reported. Children that need CT scans for traumatic brain injuries often need sedation, without needing and IV line for that. Chloral hydrate is an hypnotic agent used since 1832 with low incidence of adverse events; however, despite its worldwide use, it's being abandoned due to bitter taste, long time of sedation onset, vomiting and mild sedation. Intranasal midazolam, on the other hand, produces high and fast concentrations on CSF with greater rates of success but probably with higher adverse events. There are no prospective studies with large series of patients using intranasal midazolam. The aim of this study is to determine if nasal midazolam is a safer approach and more effective sedative regimen when compared to rectal chloral hydrate to children undergoing CT scans.
Effect of Ketamine (Ketalar) on Intracranial Pressure
Traumatic Brain InjuryIntracranial HypertensionObjectives: Ketamine is an effective, short-acting anesthetic drug, which does not decrease blood pressure. It is widely stated that Ketamine increases intracranial pressure (ICP), which prevents its use in many emergency situations, specifically in patients with traumatic brain injury (TBI) and with increased ICP. Based on previous clinical experience, we hypothesized that Ketamine decreases - rather than increases - ICP. Methods: Prospective, controlled, clinical trial. Children with ICP monitoring will receive a single Ketamine dose (1-1.5 mg/kg) either for increased ICP and/or before a potentially distressing activity. Hemodynamic variables, ICP and cerebral perfusion pressure (CPP) will be recorded 1 minute before and every minute for 10 minutes following Ketamine administration (Before/after design).
Efficacy of Pharmacological Treatment of Working Memory Impairment After Traumatic Brain Injury:...
Traumatic Brain InjurySevere Traumatic Brain InjuryThis study is designed to examine the effects of a wake-promoting agent (Modafinil) on working memory (WM) in persons with moderate to severe TBI utilizing a double blinded placebo controlled methodology. Our approach is to evaluate participants with BOLD fMRI and a limited neuropsychological battery to examine WM performance before and after pharmacological intervention. Hypotheses Because increased cognitive effort (as a function of decreased efficiency after TBI) is presumed to underlie fMRI activation dispersion that is seen during central executive WM tasks, we anticipate an attenuation of cerebral activation in prefrontal cortex during pharmacological intervention with Modafinil when compared to placebo administration on the mPASAT and vigilance testing. There will be a correlation between the decreased dispersion of the fMRI signal on scans and improvement in neuropsychological measures when individuals are on Modafinil that is not seen when they are taking placebo.
Intensive Insulin Therapy for Strict Glycemic Control in Neurosurgical Patients: Safety and Efficacy...
Subarachnoid HemorrhageTraumatic Brain Injury1 moreStrict glycemic control improves mortality and morbidity of patients admitted to the postoperative intensive care unit (ICU). The investigators would like to know if this therapy could improve the long term neurologic and cognitive outcomes of patients treated for acute subarachnoid hemorrhage with either a surgical or intravascular approach.
Treatment of Citalopram for Anxiety Disorders Following a Traumatic Brain Injury
Traumatic Brain InjuryThe proposal will assess the effectiveness of SRI treatment of anxiety following TBI. We hypothesize that participants will report significantly fewer and less severe anxiety symptoms after a 12-week course of citalopram than after a 12-week course of placebo.
Personalized, Augmented Cognitive Training (PACT) for Service Members and Veterans With a History...
Traumatic Brain InjuryMild traumatic brain injury (TBI) is a common medical condition that occurs when a head injury causes someone to lose consciousness, feel dazed or confused, or be unable to remember events occurring immediately after the injury. While most individuals with mild TBI recover within weeks or months, some individuals with mild TBI report chronic symptoms such as difficulty with cognitive skills like attention, learning, or memory, along with other symptoms such as irritability or headache. Previous studies, including those conducted by our scientific team, have shown that cognitive rehabilitation can help patients with persistent symptoms after mild TBI return to full duty, work, school, and other important life activities. Specifically, cognitive rehabilitation can provide lasting improvements in thinking abilities, functional capacity, post-concussive symptoms, and quality of life after mild TBI. However, effective interventions are still out of reach for many service members and Veterans with TBI. For patients who have returned to duty, employment, or education, scheduling up to 60 hours of treatment (a typical treatment schedule in many settings) may not be feasible. Additionally, some patients may live in areas where it is burdensome to make numerous visits to a medical center. Personalized Augmented Cognitive Training (PACT) compresses treatment into six hours of once-weekly personalized, one-on-one training by selecting treatment modules based on patient needs and priorities-substantially reducing the total amount of time required to complete treatment. PACT can be offered either in-person (in clinic) or via home-based video telemedicine, depending upon patients' preferences. Additionally, PACT includes training and encouragement for service members and Veterans to make self-directed use of mobile apps that train cognitive skills and strategies.The primary goal of this study is to evaluate whether PACT is effective at improving cognition, symptoms, and functional outcomes among military service members and Veterans with a history of mild TBI. The study will also yield information about factors that can enhance or interfere with treatment, such as number of previous TBIs, presence of post-traumatic stress; and choice of in-person vs. video telemedicine delivery of care.
The Effects of Transcranial Direct Current Stimulation (tDCS) and Cognitive Training in Patients...
Traumatic Brain InjuryClosed Traumatic Brain Injury1 moreLong-term sequelae in TBI is a well-recognized burn. We designed a proof of concept study, randomized, double-blind, placebo-controlled to evaluate 36 adult TBI patients. To evaluate the early and late effects of 10 days of 20 minutes applying transcranial direct-current stimulation (tDCS) in the dorsolateral prefrontal cortex (DLPFC), bilateral temporal cortex (CTB) and compare to sham stimulation, and online cognitive training. We expect that the active group will differ from the sham group, showing larger effect sizes in the cognitive assessment.
Co-ultra PEALut Enhances Neuronal Recovery Following Moderate Traumatic Brain Injury
Traumatic Brain InjuryTraumatic brain injury (TBI) typically provokes secondary injury mechanisms, including the dynamic interplay between the ischemic, inflammatory, and cytotoxic processes. Moreover, such an impact induces a substantial level of cell death and results in the degeneration of the dendrites, thereby leading to persistent motor, sensory, and cognitive dysfunction. Previous studies have shown that the adult-born immature granule neurons in the dentate gyrus are the most susceptible of all the cell types in the hippocampus to damage following a moderate TBI due to a controlled cortical impact (CCI) device. Currently, there is no efficient approach available for avoiding immature neuron death or degeneration following TBI. Hence, this study aimed to assess the neuro-regenerative properties of co-ultramicronized PEALut (Glialia®), which is composed of palmitoylethanolamide (PEA) and the flavonoid luteolin (Lut), in an in vivo model of TBI, as well as in patients affected by TBI.
