Days after an initial injury a damaging second wave is found in some traumatic brain injury patients and British researchers are searching for the reason why.

Nearly 1 million patients with TBI annually in the US experience a baffling second round of brain damage within days of the initial injury while they seem to be “recovering”.  Clinical trials are now in progress using a Monitoring Device that is able to monitor second by second brain chemistry.  This device which is being developed at the Imperial College in London uses the “microfluidic method” to measure glucose rapidly as an indicator of activity in fractions of a second

What researchers call depolarization is  a decreases in brain activity in patients following initial trauma spreading from the injury site with chemical changes and knocking out nerve cells. Researchers say taking large amounts of glucose to reactivate the cells makes monitoring glucose levels help the doctors tell if a patient is taking a turn for the worse.

This new device is also being tested on patients who have suffered stroke or aneurysm.

The study was published in Chemical & Engineering News.
