"What have been initially diagnosed as the mildest of concussions have sometimes turned into multi-year ordeals of headaches, light sensitivity, depression, and inability to focus, so let's hope for the best, as should certainly the medical team that cleared Azarenka to play.
It was those doctors who had the holes in their heads, not the USTA for refusing to leave a hole in its schedule, insisting on playing in temperatures that on Arthur Ashe court yesterday, reached 111 degrees at 3:05 p.m."
These are the words of Jay Greenberg. He is referring to what is called post-concussion syndrome, which--if it occurs at all--usually lasts no longer than three months, though there are cases that linger beyond that time period. The existence of post-concussion syndrome does not correlate to the severity of one's injury; a mild concussion can lead to continued symptoms.
Victoria Azarenka, who fell and hit her head prior to playing her second-round match at the U.S. Open yesterday, was examined by doctors and was supposedly being monitored while she was on court. She exhibited obvious symptoms of concussion, and--while she may have been cleared to play because she seemed just fine at the time--there is a question about why the onset of obvious symptoms did not result in early medical intervention.
