Traumatic brain injury induces secondary injury that contributes to neuroinflammation, neuronal loss, and neurological dysfunction. One important injury mechanism is cell cycle activation which causes neuronal apoptosis and glial activation. The neuroprotective effects of both non-selective (Flavopiridol) and selective (Roscovitine and CR-8) cyclin-dependent kinase inhibitors have been shown across multiple experimental traumatic brain injury models and species. Cyclin-dependent kinaseinhibitors, administered as a single systemic dose up to 24 hours after traumatic brain injury, provide strong neuroprotection-reducing neuronal cell death, neuroinflammation and neurological dysfunction. Given their effectiveness and long therapeutic window, cyclin-dependent kinase inhibitors appear to be promising candidates for clinical traumatic brain injury trials.

Background: Direct carotid-cavernous fistulas (CCFs) are relatively rare but dangerous complications of penetrating traumatic brain injury or maxillofacial trauma. A variety of clinical signs have been described, including ophthalmological and neurological ones. In some cases, severely altered cerebral blood flow can present as massive life-threatening bleeding through the nose, subarachnoid hemorrhage, and/or intraparenchymal hemorrhage.

Aim: To explore the trajectories of consciousness recovery and prognosis-associated predictors in children with prolonged disorder of consciousness (pDoC).
Method: This single-centre, retrospective, observational cohort involved 134 (87 males, 47 females) children diagnosed with pDoC and hospitalized at the Department of Rehabilitation at the Children's Hospital of Chongqing Medical University in China. The median onset age was 30 (interquartile range [IQR] 18-54) months, with onset ages ranging from 3 to 164 months.

Concussions are a common form of mild traumatic brain injury characterized by a transient alteration of cerebral function leading to a range of physical, cognitive, and emotional symptoms. Postconcussive symptoms (PCSs) usually resolve in about a week but can persist in 10% to 15% of patients. If left untreated, PCS can profoundly affect a patient's life.

Background: The pathomechanism of blast traumatic brain injury (TBI) and blunt TBI is different. In blast injury, evidence indicates that a single blast exposure can often manifest long-term neurological impairments. However, its pathomechanism is still elusive, and treatments have been symptomatic.

Background: Research on older adults who sustain a traumatic brain injury (TBI) has predominantly been on civilian, nonveteran populations. Military populations experience higher rates of TBI and often experience the additive effects of TBI and other comorbid disorders, including posttraumatic stress disorder and/or substance use that may increase disability over time.
Objective: To investigate predictors of functional independence trajectories over the 5 years after TBI in veterans 55 years or older at injury.
