Oh, what a surprise! It turns out that calling a traumatic subarachnoid hemorrhage (tSAH) after a traumatic brain injury (TBI) “mild” because it’s the only thing that shows up on a CT scan might be a bit of an oversimplification. Who would have thought, right? In a groundbreaking revelation by the Transforming Research and Clinical Knowledge in Traumatic Brain Injury Study (TRACK-TBI; because we love a good acronym), they’ve discovered that, lo and behold, there might be more going on in the brain than what meets the CT’s eye.
So, they rounded up some participants, all of whom were lucky enough to score between 13-15 on the Glasgow Coma Scale (GCS) after their TBI, showing up at the emergency department looking relatively okay on the outside. These participants had the distinct pleasure of not only getting a head CT within 24 hours of their injury but also a brain MRI two weeks later, and let’s not forget the cherry on top: a venipuncture for plasma glial fibrillary acidic protein (GFAP) analysis. Sounds like a party, doesn’t it?
Out of 57 partygoers, with a median age of 46 (because apparently, TBIs are no respecter of youth), 45.6% had CT-occult traumatic intracranial lesions discovered on their MRI. That’s nearly half, for those who prefer plain English. These hidden treasures included such delights as axonal injury, subdural hematoma, and intracerebral contusion. And guess what? Those with these hidden injuries had higher levels of GFAP, suggesting this protein might just be the secret handshake for finding CT-occult injuries.
But wait, there’s a catch! The study authors, in a moment of humility, remind us that we should take these findings with a grain of salt due to the “modest” sample size. So, in other words, they’ve peeked behind the curtain of the brain’s mysteries, but they’re not quite ready to put on a full show. Stay tuned for the sequel, which might come out once they’ve convinced more people to join their MRI party.
In the meantime, let’s all agree to stop calling anything in the brain “mild” until we’ve looked a little closer. Because, as it turns out, the brain is a complex and sneaky organ that doesn’t like to reveal all its secrets on the first date.
