Doris Roberts died from a "massive stroke."
The Everybody Loves Raymond star - 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 obtained by TMZ.com, she had a "large hemorrhagic cerebrovascular accident."
However, 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.
Her second husband, writer William Goyen, passed away after a battle with leukaemia in 1983, 20 years after they tied the knot.
