Major Traumatic Brain Injury Can Raise Dementia Risk
Patients with brain bleeding and a long hospital stay were 1.5 times more likely to develop dementia compared to those with no injury.
U.K., U.S. Research Groups Report Progress on Objective Concussion Test
Word that a saliva test can accurately identify whether an individual has sustained a concussion has created quite a buzz in recent weeks.
Plasma Biomarker May Indicate When Athletes Can Return to Play After Concussion
A better understanding of these biomarkers may help improve health and safety of athletes.
Neuropathology and Dementia in Football Players With CTE
The authors of a cross-sectional study involving analysis of data from the ongoing Understanding Neurologic Injury and Traumatic Encephalopathy (UNITE) study found that dementia is likely a result of neuropathologic changes associated with repetitive head injury as well as non-head trauma-associated vascular pathologic changes in patients with chronic traumatic encephalopathy.
Significance of Brain Microbleeds After Traumatic Brain Injury
Traumatic microbleeds are common in patients with any severity of traumatic brain injury and may be a useful biomarker to predict clinical outcomes.
Cognitive-Motor Dissociation in Patients Admitted to ICUs After Acute Brain Injuries
In a large, prospective, single-center study, more than one in six patients with acute brain injuries may have cognitive-motor dissociation (CMD) (e.g., they harbor capacity to modulate their brain activity in response to motor commands while remaining behaviorally unresponsive at the bedside). Some acute CMD patients were found to have a much higher chance for recovery of neurological functions and for reaching independent levels of activities of daily living by 12 months after brain injury.
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.
