Day-to-day variability of post-concussion-like symptoms reported over time by a non-concussed cohort.
To explore the change (trend) in post-concussion-like symptoms reported over time. ⋯ The data indicated that non-concussed participants exhibited considerable individual variability in the symptom scores reported over time. However, some participants showed a systematic decreasing trend in their symptom scores reported over the 7 days. Caution must be exercised in interpreting the serial symptom scores that are obtained following a concussion, given that this study was conducted in a non-concussed cohort.

Cranioplasty is the surgical answer to cranial defect due to decompressive craniectomy in order to increase patient's safety and for cosmetic reasons. Two main neurological sequelae of skull breaches have been described and cranioplasty has been suggested as a way to treat these neurological symptoms, but its effects on cognitive and motor functions are still unclear. ⋯ Cranioplasty affects the cognitive profile with a non-specific pattern of change. Timing of the cranioplasty plays a key role to enucleate cognitive improvement, indeed greater cognitive changes were seen in patients who had cranioplasty within 6 months following the injury. Thus, cranioplasty must be considered a key factor in neuropsychological recovery and should be performed as soon as possible following the injury in order to take advantage of the window of opportunity for rehabilitation.

Injury of the inferior cerebellar peduncle in patients with mild traumatic brain injury: A diffusion tensor tractography study.
No study on injury of the inferior cerebellar peduncle (ICP) in patients with mild traumatic brain injury (mTBI) has been reported. This study, using diffusion tensor tractography (DTT), attempted to demonstrate injury of the ICP in patients with mTBI. ⋯ Evaluation of the ICP using DTT would be useful in patients with a balance problem after mTBI.

Review Case ReportsAlzheimer's disease and chronic traumatic encephalopathy: Distinct but possibly overlapping disease entities.
Alzheimer's disease (AD) and chronic traumatic encephalopathy (CTE) have long been recognized as sharing some similar neuropathological features, mainly the presence of neurofibrilary tangles and hyperphosphorylated tau, but have generally been described as distinct entities. Evidence indicates that neurotrauma increases the risk of developing dementia and accelerates the progression of disease. Findings are emerging that CTE and AD may be present in the same patients. ⋯ This case series and review of the literature presents a discussion of AD and CTE in the context of neurotrauma. It highlights recent work from repetitive neurotrauma models with an emphasis on those exhibiting a CTE-like phenotype. Potential mechanisms of interest shared amongst AD and CTE are briefly addressed and future experiments are advocated for to enhance understanding of CTE pathophysiology and the relationship between CTE and AD.

ReviewThe effects of anaemia and transfusion on patients with traumatic brain injury: A review.
Anaemia in traumatic brain injury (TBI) is frequently encountered. Neurosurgical texts continue to recommend transfusion for hematocrit below 30%, despite clear evidence to do so. Transfusion should increase oxygen delivery to the brain, but it may also increase morbidity and mortality. ⋯ No division of response based on gender difference or impact of anaemia in the post-hospital treatment setting was observed. A randomized control trial is recommended to determine the impact of anaemia and transfusion on detailed outcome assessment in comparison of transfusion thresholds ranging from ≤ 7 g dL-1 to ≤ 9 g dL-1 in patients with moderate-to-severe TBI.
