The study detailed the case of a German heavy metal fan suffered bleeding in the brain after a night of headbanging at a MOTÖRHEAD concert. The 50-year-old complained of a two-week constant headache while being treated at Hannover Medical School and told doctors that he had been headbanging regularly for years. A CT scan showed he suffered from bleeding — medically known as chronic subdural haematoma — on the right side of his brain.
"We are not against headbanging," said Dr. Ariyan Pirayesh Islamian, one of the doctors who treated the patient. "The risk of injury is very, very low. But I think if (our patient) had (gone) to a classical concert, this would not have happened."
"There are probably other higher risk events going on at rock concerts than headbanging," Dr. Colin Shieff, a neurosurgeon and trustee of the British brain injury advocacy group Headway, added. "Most people who go to music festivals and jump up and down while shaking their heads don't end up in the hands of a neurosurgeon."
Although Megadeth Front Man Dave Mustaine has expressed his issues from headbaning,
Slayer Mainman Tom Araya had to undergo some surgeries as well and stated in a past interview..
"I can't headbang anymore," Araya explained in an April 2010 interview with Noisecreep. "When they diagnosed me, they found I was herniating to the left, and normally it's to the back. That was caused by headbanging. I'm an advocate of moderate headbanging now." He told KNAC.COM a month later: "Yeah, I just can't [headbang]. With a plate in your neck, it's not a good idea to do that. The only disclaimer I can have for people is there's nothing wrong with headbanging, just do it in moderation. And understand at some point it could damage you. People are gonna do what they wanna do, and as long as they are aware that this could happen to you, then they have a choice. I'm still gonna rock out, I just won't be able to metal out. [laughs]"
