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 glam rock-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 Associated Press reports.

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 Web posting.

The message said doctors are hopeful Michaels will gradually improve as the blood surrounding the brain dissolves and is reabsorbed into his system. The posting comes on the tails of a Radar Online report that Michaels' condition has been upgraded from critical to stable.

Michaels' father, Wally Sychak, told the TV show "Extra" that he had spoken by telephone with his son, hospitalized in Arizona, and said Michaels "sounded a little slow, but fine," Newsday's Frank Lovece reports. "He was talking, not as cheerful as he usually is. But I guess he is under sedation. But he understood what he was saying and knew me. Everything seemed good that way."

Sychak told the show that Michaels is regaining movement in his limbs. "They say he's moving his arms and hands - the best as they could expect at this time."
