Bret Michaels suffered stroke

Brain bleeding is causing condition leading to seizures

Tests results indicate Bret Michaels has a lack of sodium in his body that leads to seizures, according to a message posted Tuesday on the website of the rocker/reality TV star.

The condition, called hyponatremia, is a side effect of a brain hemorrhage that has left the Poison frontman in intensive care at an undisclosed hospital.

The tests also found the 47-year-old Michaels suffered a type of stroke that causes bleeding in the fluid-filled spaces around the base of the brain.

Michaels' New York-based publicist Joann Mignano provided a written statement confirming the posting.

The message said doctors are hopeful Michaels will gradually improve as the blood surrounding the brain dissolves and is reabsorbed into his system.
