Your brain can be "fine" on a standard scan and still be underperforming. That is the hidden problem Dr. Dustin Glass uncovers with SPECT imaging - and it changes how you think about concussions…

So I had, y- uh, a couple weeks ago, had a, a cheerleader come in, and, uh, with a concussion.

Normally you think of concussions coming from the flyers and, uh, you know, the ones doing all the acrobats and the tricks and everything.

I, I ordered a SPECT scan for her through the Amen Clinic, and I highly recommend people, if you've had any kind of head trauma, had any kind of concussion, not o- even if you're, you know, if you've had MRIs, CTs, anything, and it's showing the brain no active blain- brain bleed, but you're still not right, or this could be months, years after, and you're still not feeling well, I highly recommend SPECT scans because it's actually gonna give you, um, basically we're looking at blood flow as far as cognitive type blood flow, where the activity or lack of activ- uh, lack of activity is going in the brain.

The nice thing about it is one of those things with SPECT scans is that a lot of people are afraid to see what their brain looks like, 'cause again, it's showing blood flow, active blood flow-

... not like an MRI that shows the vessels, but this is where is the blood flow going during cognitive function or a concentrated study.

And so a lot of people are worried to, to see things on it, and then ha- or what, what we talk about with SPECT scans is, like, if you, if, if you, you don't know where to go, you gotta measure things, right? Just like an orthopedist is gonna look at a knee with an MRI-

The nice thing about it when I sat down with her and her mom is that we were able to discuss these areas that made sense why she was having trouble with math, right?

And, like, literally she's a very good honors AP student, and she couldn't even, like, figure out a math problem.
