Bret Michaels Has 'Warning Stroke'

Bret Michaels' quick return to the stage is looking much iffier now: He's back in the hospital after suffering what doctors term a "warning stroke." Tests also revealed he has a hole in his heart. Doctors say he's expected to make a full recovery from both and don't think they're related to his recent brain hemorrhage, reports People.

Michaels, 47, who returned to the hospital after suffering numbness on his left side, was diagnosed with a Transient Ischemic Attack. "There is no doubt that (this) is devastating news to Bret and his family," says his neurosurgeon. "The good news is that it is operable and treatable and we think we may have diagnosed the problem that caused the (TIA)."
