Drs. Oz & Roizen's Tip of the Day: Evaluating concussions

King Features SyndicateApril 18, 2014 

A couple of seasons ago, 35 of 288 players in the Swedish Hockey League suffered concussions in the first half of their season.

That's when the Swedes started testing for T-tau proteins in injured athletes' blood. These tau proteins are biomarkers, released when there's a concussion. (They're also biomarkers for conditions such as Alzheimer's and Parkinson's.) It turns out that tau levels peak during the first hour after a concussion, and the peak levels indicate the severity of the injury and how long symptoms will persist. Tau levels drop off in the next 12 hours, but often they're still higher than they should be six days later.

This simple and effective assessment objectively determines how badly the brain was traumatized (it's often not obvious), and it's going make T-tau blood-testing kits standard tools one day.

Now the NFL is testing a PET-based brain scan to detect tau proteins, as it explores their connection to chronic traumatic encephalopathy in several retired players. It's the first time these proteins have been identified in a living player suspected of having CTE. Before, as they did for Hall of Fame center Mike Webster, they had to analyze brain tissue postmortem.

Anyone with a concussion might benefit from getting T-tau protein levels measured. Tests can be done at the hospital using cerebral-spinal fluid. Knowing when it's safe to return to the field can keep you in the game - for the long run.
