Former first lady Lady Bird Johnson, 94, left an Austin, Texas, hospital Thursday following six days of tests and observation, a Johnson family spokesman said.
"Because of her stroke in 2002, her family and physicians always operate with caution," spokesman Neal Spelce said in a statement. "Everyone — especially Mrs. Johnson — is so pleased that she is home."
The widow of late President Lyndon Johnson was suffering from a low-grade fever when she was admitted on June 22 to Seton Medical Center in Austin.
The stroke has left her with speech difficulties, but she still occasionally appears at public events in Austin, the Texas capital.
Lyndon Johnson, who became president after John Kennedy was assassinated in Dallas in November 1963 and held the office until 1969, died of a heart attack in 1973 at his ranch west of Austin.
