  • In a world first, a newly authorized handheld device will allow doctors to detect traumatic brain injuries (TBIs) in under 15 minutes, potentially saving lives by dramatically shortening the time it takes to properly diagnose the issue.
  • Until now, health care providers have needed to rely on subjective measurements for TBIs, but we finally have a more objective tool to help evaluate patients.”
  • Unfortunately, many patients with mild TBI struggle to get an accurate and timely diagnosis, even as they grapple with ongoing symptoms. This ultimately results in delayed treatment.

  • often use a series of screening questionnaires, physical examinations and CT scans to take pictures of the brain in order to evaluate TBI. However, experts agree these techniques aren’t perfect and there is no objective way to reliably evaluate TBI.
  • Abbott’s new blood test may serve as an objective tool to help doctors triage TBI patients, because it relies on molecular signatures in the blood rather than on murkier clues, such as patient interviews.
  • Aside from reducing health care costs, it can save people from unnecessary radiation that has been shown to increase the risk of cancer.
  • Despite the benefits, experts agree that physicians cannot rely entirely on this diagnostic test, stating it will only serve to supplement clinical judgment.
  • "The game-changing innovation of having a tool like this is that, as it becomes more widely used, I believe we will identify more people with TBI that’s more subtle, that could be life-altering."

      We've talked about PTSD in class before, and its links to memories, thoughts, and feelings.
  • Now, researchers using magnetic resonance imaging (MRI) have found potential brain biomarkers of PTSD in people with traumatic brain injury (TBI).

      Are they just now identifying something to read from an MRI that marks PTSD? Or is it a new type of MRI? As far as I know, the type of MRI they are referring to is nothing new.

  • The relationship between TBI and PTSD has garnered increased attention in recent years as studies have shown considerable overlap in risk factors and symptoms,

      Overlap between traumatic brain injuries and PTSD. Interesting.
  • At 3 months, 77 participants, or 18 percent, had likely PTSD; at 6 months, 70 participants or 16 percent did. All subjects underwent brain imaging after injury.

      That's interesting. So, the numbers were decreasing?
  • "MRI studies conducted within two weeks of injury were used to measure volumes of key structures in the brain thought to be involved in PTSD,"

      What part of the brain is that?
  • Specifically, smaller volume in brain regions called the cingulate cortex, the superior frontal cortex, and the insula predicted PTSD at 3 months.

      Answers my previous question. I'm unfamiliar with the cingulate cortex.
  • Together, the findings suggest that a "brain reserve," or higher cortical volumes, may provide some resilience against PTSD.

      Is that something they can alter?
