Brain Injury Sends Poison Lead Singer, Bret Michaels, to the Hospital

Poison front man Bret Michaels is in critical condition following a severe brain injury, though little else has been released regarding the exact condition of the singer and reality TV star. Michaels was rushed to the hospital last Thursday and is undergoing multiple tests after suffering an intense headache, which some think may have been caused by a subarachnoid hemorrhage.

Such a hemorrhage is usually the result of a brain aneurysm, which can go undetected for years before appearing violently and seemingly out of nowhere. While millions of Americans walk around with brain aneurysms every day, according to Mayo Clinic, only a handful of these actually begin to bleed.

At last year's Tony Awards, Michael's suffered a blow to the head when he was struck by a falling set piece. While this event has been questioned as a possible precursor to the star's brain injury, most seem skeptical about its relation to Michael's current condition.

Though the details surrounding Bret Michaels brain injury and subsequent hospitalization remain hazy, it is known that doctors found bleeding at the base of his brain stem and that more tests are planned.

The odds for those suffering from a subarachnoid hemorrhage are decent, but far from ideal. According to an interview by Fox News, 25 percent of those affected die before reaching the hospital and another 25 percent will leave with some sort of permanent brain damage.
