Useability: all therapists and subjects must rate useability as good or better. Success of blind: subject accuracy at guessing group membership must be at or near 50%.

The study will explore the neurocognitive effect of four weeks of treatment with amantadine versus placebo in patients with traumatic brain injury using the Interval Bisection Timing Task. Approximately 16 individuals with traumatic brain injury are expected to participate in this study. Subject participation is expected to last up to 8 weeks with 16 study visits.

This randomized trial will compare the clinical efficacy of adding oral magnesium oxide to acetaminophen and ondansetron in the treatment of adolescents presenting within 48 hours of a mild traumatic brain injury using the Post-Concussion Symptom Severity Score Index.

Traumatic brain injury (TBI) is a leading cause of death and disability in young people. It has been called the "signature wound" of the Iraq war because of its frequency among troops. TBI is associated with many chronic disabilities. Physical alterations include reduced exercise tolerance and profound muscle weakness, whereas psychological alterations include diminished sense of well-being, depression, fatigue and anxiety. Muscle and brain tissues rely upon circulating blood amino acids as precursors for metabolic functions. The investigators have shown that even one year after injury, plasma valine, an essential amino acid (EAA), was markedly reduced in patients with TBI compared to healthy controls. The investigators speculate that low plasma valine concentration contributes to chronic fatigue after TBI, since valine and tryptophan compete for the same transporter into the brain, and a low plasma valine concentration will allow more tryptophan to be transported. As a consequence, increased brain tryptophan will increase serotonin production, which may significantly contribute to the development of fatigue. Thus, the investigators will test if restoring valine concentration in persons with TBI may reduce fatigue perception and improve physical and neuropsychological function. Further, the investigators have previously shown that EAA intake has an anabolic effect in healthy young and elderly individuals. However, no data are currently available in persons recovering from TBI. Thus,the investigators will also test if EAA and/or valine can improve muscle mass in patients with TBI.

Increase in intracranial pressure (ICP) could be associated with increase in positive end-expiratory pressure (PEEP) level. Data are however disparate and interactions between ventilation with high PEEP and intracranial circulation are still debated. Individual patient's chest wall elastance could have a key role in determining the effects of PEEP on ICP, since it dictates which proportion of the applied PEEP is transmitted to the pleural space, thus increasing central venous pressure (CVP) and reducing cerebral venous return. Measurement of esophageal pressure with a dedicated probe allows partitioning of respiratory system elastance into its lung and chest wall components, thus permitting to study this phenomenon. Multimodal intracranial monitoring permits to study the effects of PEEP on more advanced brain-specific indices such as brain tissue oxygen (PtiO2), cerebral microdialysis data, transcranial doppler ultrasound-derived flow measurements and automated pupillometry, besides ICP. This study aims to test the association between the ratio of chest wall to respiratory system elastance and PEEP-induced variations in ICP and brain-specific multimodal monitoring indices. This study will evaluate the relative role of other selected measures of respiratory mechanics, hemodynamic variables and intracranial compliance, in order to establish the role of individual respiratory mechanics in the interplay of physiological factors affecting the effects of positive pressure ventilation on the brain. Patients will undergo two periods of ventilation at two different levels of PEEP (5 and 15 cmH2O) in a randomized cross-over order. At the end of each period, cardiorespiratory clinical data, ICP and other advanced multimodal neuromonitoring data (brain tissue oxygen tension, cerebral microdyalisis analytes, transcranial doppler ultrasound and automated infrared pupillometry data) will be collected. Systematic respiratory mechanics assessment (including calculation of chest wall and lung elastances and estimation of the amount of recruitment versus overdistension due to PEEP by means of a single-breath derecruitment trial), echocardiography and arterial blood gas analysis will be performed.

The aim of this study is to assess the safety and feasibility of dexmedetomidine as an adjunct to conventional sedative therapy compared to conventional sedative therapy alone in patients with severe traumatic brain injury.

Neurocritical care is a major branch in the field of critical care medicine, and more than 50% of the neurocritical care patients in the Tibet Autonomous Region People's Hospital (TARPH) are in neurocritical care, of which cranial damage accounts for about 30%, and paroxysmal sympathetic hyperexcitability syndrome (PSH) after traumatic brain injury（TBI）is a common complication, which affects the cardiorespiratory and cerebral functions to varying degrees, and optimizing the cerebral perfusion and oxygenation supply is the key point in the treatment of TIB, and the maintenance of the cerebral homeostasis and the functional homeostasis is currently an international hotspot for treatment. Maintaining cerebral homeostasis and body function homeostasis is an international hotspot in the treatment of TIB. This study intends to elaborate on the relationship between PSH and Intracranial blood flow in patients with TBI, as well as the effect of anti-stress treatment on Intracranial blood flow. Implementation Patients with brain injury admitted to our department from January 2021 to January 2022 were included. Non-invasive transcranial Doppler ultrasound was applied to measure cerebral blood flow, non-invasive local cerebral oxygen saturation monitor to measure local cerebral oxygen saturation, and an electroencephalography bispectrometer to measure BIS score to quantify the depth of sedation during the experimental process. Bedside ultrasound monitored the right heart function and lung water status, and the data of each monitoring index were monitored and recorded throughout the whole process, and the relationship between concomitant PSH and Intracranial blood flow in TBI patients was found according to the statistical analysis. Ultimately, to achieve the control of TBI complications and improve patient rescue. To expect to achieve the purpose of improving the prognosis of TBI patients.
