According to The Guardian, the unidentified 50-year-old patient developed a blood clot and needed a hole drilled into his brain to relieve the bleeding. He had no history of head injuries, and the the problem seemed to stem from rocking out too hard at a singular Motorhead concert.
However, metal fans shouldn’t get too concerned. This was a rare incident, and the medical specialists who treated the man say that headbanging, for the most part, is safe. “We are not against headbanging,” said Dr. Ariyan Pirayesh Islamian. “The risk of injury is very, very low. But I think if [the patient] had gone to a classical concert, this would not have happened.”
The report on the man’s brain clot was published in the latest edition of The Lancet medical journal, in which doctors described headbanging as “a contemporary dance form consisting of abrupt flexion-extension movements of the head to the rhythm of rock music, most commonly seen in the heavy metal genre.” They went on to describe Motorhead as “one of the most hard-core rock ‘n’ roll acts on Earth.”
