Researchers test blood flow in athletes’ brains to find markers that diagnose concussions

A hard hit to the head typically prompts physicians to look for signs of a concussion based on symptoms such as forgetfulness, wobbly gait and disorientation. But symptoms such as those are subjective, says physiologist Sushmita Purkayastha, Southern Methodist University, Dallas. Now a new study aims to find noninvasive objective indicators to diagnose whether an athlete has suffered a concussion.
