New Study Finds Sub-Concussive Hits To The Head May Cause Brain Damage

BOSTON (CBS) Another warning about repetitive head injuries in sports: A new study finds that it doesn’t take a full-blown concussion to cause brain damage. Researchers at Carnegie Mellon University and the University of Rochester Medical Center placed accelerometers in the helmets of 38 college football players to measure the number and intensity of impacts to the head. They also scanned their brains with MRIs before and after football season. While only two players were actually diagnosed with concussions, more than two-thirds of the players were found to have evidence of white matter damage in their brains by the end of the season. And the amount of damage was correlated with the number of hits the players took to their heads, suggesting that it’s not just big blows that matter but that more minor dings can also add up.

_______________ For Banner Health, one of the largest non-profit health system in the United States, finding ways to make health care easier and better for our patients is at the root of everything we do. That’s why we are making significant investments into the digital health and neurotech space, trying to answer some common pain points. Let me give you an example. Last year, Banner Urgent Care turned to an innovative device, BrainScope One, to provide better care and to help save patients money and time, as it helps clinicians identify traumatic brain injuries and concussions. This is an area of growing concern. St...

Conclusion: There are no differences in 1H MRS measurements in the acute concussive period; however, changes in glutamate+glutamine and myo-inositol concentrations detectable by 1H-MRS may develop beyond the acute period.

Conclusions: Trends in PET suggest that acute phase (31-94 hours after injury) is hypometabolic across whole brain, with a similar trend in a small number of gray matter areas on the left side. The degree of hypometabolism (as assessed by acute/follow-up SUV) increases across this time window, suggesting that the lowest metabolic state occurs at even later times. The degree of hypometabolism (as assessed by acute/follow-up GM/WM ratio) may reflect clinical severity. MRI analysis of CBF and CMRO2 is ongoing.

The objective of this study was to evaluate if the altitude related factors (hypoxia/hypobaria) confound glucose uptake in TBI as measured by FDG uptake. Methods: Adult male C57BL/6J mice (n=32, 6-8 weeks) were used in this study. FDG PET and CT images were acquired using a Siemens Inveon preclinical scanner (Siemens Medical Solutions, Erlangen, Germany) at three time points - (1) before exposing the animals to hypobaric conditions (5000 meters) [baseline], (2) after 12 weeks of high-altitude exposure or at sea-level [week 12] and (3) 12 days after a repetitive closed head injury or sham injury [post-TBI]. The PET/CT data ...

In conclusion, more descriptive researches are needed in different athletic populations and settings. Furthermore, experimental designs aimed at investigating the effects of PBs manipulation on recovery and the putative mechanisms are encouraged. The attentionon recovery in sport has increased enormously in the last years and, nowadays, it is almost as important as training for performance and sport success. A plethora of recovery strategies has been developed in the last years including active and passive recovery, cold-water immersion, compression garments, massage and many others, but some of them lack scientific e...

Conclusion We have reviewed the literature and identified blood biomarkers with the highest discriminative abilities as determined by operating characteristics in four commonly encountered clinical situations: diagnosing concussion, predicting the need for a CT scan after mTBI, predicting delayed recovery after mTBI, and predicting poor outcome after sTBI. The top performers in each category may provide insight into pathogenic mechanisms of TBI that most influence the measured endpoint. Nonetheless, many challenges remain before these biomarkers can be incorporated into clinical practice. In particular, it remains unclear...
