Bret Michaels Suffers Medical Complication After Brain Hemorrhage

Bret Michaels' fight back to fitness following his brain hemorrhage on April 22 has suffered a blow, with news that he's suffering from a condition that causes seizures.

A post on the 47-year-old Poison singer's Facebook page today read, "Test results indicate a setback in Bret Michaels' condition, a side effect from the brain hemorrhage called hyponatremia, a lack of sodium in the body which leads to seizures." He remains in intensive care at an undisclosed location.

Michaels was struck down with a subarachnoid hemorrhage, which results in bleeding at the base of the brain. The most common cause is a spontaneous rupture, but some people have speculated that an incident at last year Tony Awards might be responsible when Michaels was hit on the head by a prop.

According to CNN's chief medical correspondent, Dr Sanjay Gupta, speaking on Larry King Live on April 26, only 30 percent of sufferers make a full recovery. Michaels' Facebook post was more upbeat however, and said doctors were "hopeful that Bret will gradually improve as the blood surrounding the brain dissolves and is reabsorbed into his system."

Poison enjoyed considerable success in the '80s. The glam rockers' first three albums -- 'Look What the Cat Dragged In,' 'Open Up and Say ... Ahh!' and 'Flesh and Blood' -- all went multi-platinum in the US, selling over ten million copies in the process. Although Poison have been less successful in recent years, Michaels has forged a career as a reality TV star. He has appeared in two series of VH1's dating series 'Rock of Love' and is currently being seen onscreen as a contestant in NBC's 'Celebrity Apprentice.'
