The last 20 years has seen the emergence of a sub-category of the mild traumatic brain injury literature termed 'sport-related concussion'. Some important differences now exist between this sub-category and the wider findings in the field and these could be detrimental to patients with persisting post-concussion symptoms (PCS). Sport-related studies often emphasize the cerebral risks associated with concussive injuries whilst the broader literature typically focuses on the relatively benign organic implications and the role of psychological factors in persisting symptoms. Clinically, anxiety caused by these mixed messages could lead to an exacerbation of PCS. This paper summarizes the commonalities and differences between the literatures and addresses the key clinical implications.

Introduction: Neurogenic bladder dysfunction is a prevalent condition characterized by impaired bladder control resulting from neurological conditions, for example, spinal cord injury or traumatic brain injury (TBI). Detrusor overactivity is a typical symptom of central nervous system damage. A lesion affecting the pontine neural network typically results in loss of tonic inhibition exerted by the pontine micturition center and causes involuntary detrusor contractions.

Acute stress disorder (ASD) is a transient psychiatric disorder that may arise subsequent to abrupt, extreme trauma exposure, and serves as a reliable indicator for the subsequent development of posttraumatic stress disorder (PTSD) (Bryant, 2011; Battle, 2013). It exhibits rapid progression in the aftermath of trauma and persists for a duration of days or weeks (not exceeding one month), manifesting symptoms of dissociation, re-experiencing, avoidance, and hyperarousal (Bielas et al., 2018).

Obstructive sleep apnea (OSA) has been associated with structural and functional brain changes and cognitive impairment in sleep clinic samples. Persons with traumatic brain injury (TBI) are at increased risk of OSA compared to community samples, and many experience chronic cognitive disability. However, the impact of OSA on cognitive outcome after TBI is unknown.

Background: Traumatic brain injury (TBI) is a major public health concern worldwide, contributing to high rates of injury-related death and disability. Severe traumatic brain injury (sTBI), although it accounts for only 10% of all TBI cases, results in a mortality rate of 30-40% and a significant burden of disability in those that survive. This study explored the potential of metabolomics in the diagnosis of sTBI and explored the potential of metabolomics to examine probable primary and secondary brain injury in sTBI.

The zeta inhibitory peptide (ZIP) interferes with memory maintenance and long-term potentiation (LTP) when administered to mice. However, mice lacking its putative target, protein kinase PKMζ, exhibit normal learning and memory as well as LTP, making the mechanism of ZIP unclear. Here we show that ZIP disrupts LTP by removing surface AMPA receptors through its cationic charge alone.
