Statin Use Moderately Reduces Dementia Risk After Concussions in Older Individuals
In a large population study, concussion in older adults resulted in significantly higher risk for dementia that was modestly reduced among those taking a statin.

Tau PET Is Promising as a Diagnostic Agent in Chronic Traumatic Encephalopathy
Former NFL players with symptoms consistent with chronic traumatic encephalopathy had increased tau tracer uptake that was associated with years of playing football but not with cognitive or neuropsychological measures.

Measurement of Brain Vital Signs in Concussed Athletes
These investigators prospectively studied auditory event-related potentials (ERPs) in junior competitive male ice hockey players and identified a pattern of ERPs that distinguishes acutely concussed from non-concussed players, establishing this noninvasive, easy-to-administer test as a biomarker to assist trainers, coaches, and clinicians with making the diagnosis of concussion.

Are Women More Prone to Brain Injury Than Men When Playing Soccer?
Repeated subconcussive injuries to the brain, such as “heading” the ball in soccer, result in more severe injury and slower recovery in women compared to men.

Hypercapnic Acidosis and Clinical Outcomes in Patients With Acute Brain Injury
In this multicenter retrospective study, hypercapnic acidosis was associated with worse clinical outcomes in mechanically ventilated patients with acute brain injury.

What Are the Early Predictors for Post-traumatic Epilepsy After Injury?
Following traumatic brain injury, early (first five days after injury) epileptiform abnormalities on EEG were seen more commonly in patients with subsequent post-traumatic epilepsy (PTE), compared to controls, and were found to be a significant and independent predictor of PTE. The presence of subdural hemorrhage was the only other independent predictor of PTE.

Intracranial Pressure Changes in Mild Traumatic Brain Injury
After an exhaustive review of the animal and human studies literature regarding mild traumatic brain injury (mTBI), Haider et al. did not reach consistent conclusions regarding evidence for intracranial pressure elevation in human patients who sustain an mTBI.

Prediction of Persistent Post-concussion Symptoms After Mild Traumatic Brain Injury
Persistent post-concussion syndrome may last for more than six months, and risk factors include female sex, neck pain, headache, and post-concussive symptoms at two weeks after the injury.

Salivary microRNA as Biomarker to Predict Prolonged Concussion Symptoms
In a prospective cohort study of pediatric patients, aged 7 to 21 years, diagnosed with concussion, salivary microRNAs were found to be a potential biomarker for predicting prolonged concussion symptoms.

TBI in Prodromal Parkinson’s Disease
This population-based study using Medicare data demonstrated that in the five years prior to diagnosis of Parkinson’s disease (PD), when compared with age-matched controls, those who were diagnosed with PD had a higher incidence of traumatic brain injury (TBI). The TBI was rated as mild and concussive and was most often related to falls.
