As Bret Michaels begins what may be a slow and painful recovery from a brain hemorrhage, the rocker got another round of bad news at the intensive care unit: He was diagnosed with a side effect that leads to seizures, his reps tell PEOPLE.
“Michaels remains under 24-hour observation in the ICU and is in positive spirits. He is responding well to tests and treatments,” the reps say in a statement. “Even though today was a minor setback, doctors remain hopeful for a full recovery.”
Michaels, 47, is conscious and in critical but stable condition at the unidentified hospital after suffering a type of stroke called a subarachnoid hemorrhage, which causes bleeding in the fluid-filled spaces around the base of the brain.
Additional tests are planned to find the cause of the rupture, his reps say, adding, “Many people are speculating Michaels’s head injury suffered from a prop striking the singer at the Tony Awards last June is the cause.” But for many patients with this condition, no cause is often found.
