'Quantifiable cerebral blood flow changes have been shown to occur following concussion and may enable objective diagnostics however, these results are limited to advanced MRI techniques.

'A challenge with concussion assessment is the reliance upon subjective symptoms rather than objective measures based on physiological changes,' he noted.

'While such changes may be detected with MRI, we believe there may be a less expensive and portable way to measure these changes with a transcranial Doppler device.' Moisture from a tropical wave that moved out of the Gulf and over Mexico. 'There is growing evidence that concussions can change the blood flow in the brain,' Hamilton said in a press statement. Accordingly, it can be challenging to pinpoint the exact areas that are susceptible to damaging winds using an operational Doppler radar. That is expected to change Monday as an active weather pattern continues across Texas.

In comparison, traditional transcranial ultrasound that measured cerebral blood flow was only about 60% accurate in diagnosing concussion, he reported in an emerging science presentation at the American Academy of Neurology annual meeting. Minute-by-minute weather using WHIO-TV Channel 7s StormTracker Doppler Radar and. The imaging studies were able to differentiate between healthy and concussed athletes 83% of the time, reported Robert Hamilton, PhD, of Neural Analytics in Los Angeles, and colleagues.
