"As followers of celeb gossip are well-aware, the former Poison singer (and current Celebrity Apprentice star) was finally released from the hospital yesterday. He had been in &amp;quot;serious condition&amp;quot; for more than a week, after he suffered a subarachnoid hemorrhage on April 22nd. What exactly is a subarchnoid hemorrhage? Here are some answers from Michael J. Alexander, MD, director of the Neurovascular Center at Cedars-Sinai Medical Center in Los Angeles: The definition A subarchnoid hemorrhage is bleeding that occurs just outside the surface of the brain. It can be caused by a head trauma (like in an accident), or it can happen spontaneously. If it&amp;#039;s spontaneous, the most common cause is a brain aneurysm\u2014a weak, ballooned out part of an artery that ruptures. Blood vessel malformations, inflammation of the arteries, and high blood pressure can also cause a spontaneous hemorrhage.   What&amp;#039;s the treatment? It depends on the cause. If it&amp;#039;s caused by an aneurysm, then the patient will most likely need to undergo a procedure to seal off the ruptured area.  How good (or bad) are the odds of surviving this? Again, it depends upon what caused it, but if it&amp;#039;s due to an aneurysm then there&amp;#039;s about a 50-50 chance of survival.  How common is it?  There are about 30,000 spontaneous subarachnoid hemorrhages in the U.S. per year. It&amp;#039;s most common among people in their late 50s or early 60s, and more women than men are affected. Is there anything you can do to prevent it?  Most of the time, no. But if you have high blood pressure, getting it down will reduce your risk. And don&amp;#039;t smoke or use (non-prescription) stimulant drugs. Photo credit: Retna \u2014Barbara Brody, Health Editor "^^<http://www.w3.org/2001/XMLSchema#string>
