The actress, who was known for playing busy-body mother Marie Barone in the hit show, passed away last month at the age of 90 and, according to her death certificate she had a "large hemorrhagic cerebrovascular accident," reported TMZ.
The legendary actress' cause of death didn't come as too much of a surprise to doctors as she'd been suffering with hypertension, a term meaning abnormally high blood pressure, for many years and was on medication for it.
Doris is survived by her son Michael Cannata Jr, from her first marriage to Michael Cannata, which ended in divorce in 1962, and her three grandchildren.
Doris won five Outstanding Supporting Actress Emmy Awards during her career, four for "Everybody Loves Raymond" and one for "St Elsewhere: Cora and Arnie".
