EDISON - Medical experts say a new trend called the "Knockout Game" isn't a game at all, and puts targets' lives in danger.
Dr. Chris Freer, chair of emergency medicine at St. Barnabas Hospital, says any of the knockout game incidents, which have gained popularity after being posted online, could lead to traumatic brain injury.
Janice Smith-Zeigler of Newark says she was left with headaches after nearly being knocked out in a recent attack.
A Paterson high school student was dazed after being knocked out this week.
In September, a Hoboken a man may have lost his life to teens playing the knockout game.
"One hard blow on someone who's not expecting this to happen is a higher risk of injury," Freer says.
The act can cause a concussion, which is a shaking of the brain, according to Freer. Victims can have long-term consequences like memory problems and headaches.
Smith-Zeigler considers herself lucky for not being knocked unconscious. Freer says blacking out holds a higher risk of a concussion.
He says professional fighters train and know blows are coming. Random knockout victims could end up with slow or fast internal bleeding.
"You could die if you're not treated for an epidural hematoma quickly," Freer says.
Both doctor and victims agree knockout games must end. "We want peace and we want the community to come forward and to face this problem," says Muhammad Kamrul Huda, the brother of the Paterson victim.
Dr. Freer says blows to the head could tear veins or arteries causing major bleeding, and says the elderly have fragile blood vessels, so simple force could have major effects.
