Former President Jimmy Carter has been admitted to a hospital in Atlanta for a procedure to relieve pressure on his brain caused by recent falls, the Carter Center said Monday.

The former president’s organization made the announcement in a tweet on Monday, adding that Carter’s procedure will take place Tuesday morning.

Carter, who is 95 and the oldest living former president, was injured in two falls this year, one in the spring and one in October.

He received 14 stitches after his spill in October, but traveled the same day to Nashville, Tennessee, to rally volunteers and, later, help build a Habitat for Humanity home.

Carter needed hip-replacement surgery after he fell in May.

On Monday, the Carter Center said the former president is “resting comfortably, and his wife, Rosalynn, is with him.”

He’ll undergo the procedure at Emory University Hospital.
