Dr. Richard Fessler, a neurosurgeon at Northwestern Memorial Hospital where the senator is being treated, said Kirk's condition has been upgraded to good and he will be able to start rehabilitation soon. "He is visiting with family and even watched the Super Bowl last night," Fessler said.
Doctors at Northwestern Memorial Hospital said they removed part of the 52-year-old's skull to help relieve the pressure on his brain following swelling caused by a stroke. The senator checked himself into Lake Forest Hospital in late January after having headaches and dizziness. He was transferred to Northwestern Memorial Hospital the next day. Tests showed he had an ischemic stroke on the right side of his brain.
