Roberson, 55, was admitted to Medical College of Georgia Hospital on Feb. 22 after complaining of headaches and fatigue, which tests determined were caused by a cerebral hemorrhage. He underwent surgery Feb. 24 to relieve brain swelling and pressure.
That was all the result of an arteriovenous malformation, or an abnormal collection of blood vessels in his brain, according to previous statements from his family.
"As indicated in the update released on Thursday, February 24th, Dr. Roberson's progress is expected to be gradual and steady over time," said Doris Roberson, the superintendent's wife, in the statement Monday. "This process normally occurs over an average of four to six months.
"His care will include continuing treatment and therapy by his hospital physicians for his Arteriovenous Malformation condition followed by a period of rehabilitation after his release from MCG Health."
Roberson's progress is slow, his wife said, but he is showing gradual improvement.
"While he is not expected to return physically this school term, we look forward to the continuation of the pattern of progress that he has demonstrated as he moves through his continued treatment, regaining of strength, and overall recuperation," Doris Roberson said.
The school board named Deputy Superintendent James Whitson the acting superintendent at a special meeting March 1.
"We have been touched profoundly by the many acts of kindness expressed toward Dr. Roberson and our family," Doris Roberson said. "We extend our earnest appreciation to the CSRA community, including the students, teachers and staff of Richmond County Schools for your many prayers and thoughtful gestures."
