Reports confirmed that she was fully conscious at the time of her death after experiencing a sudden health crisis and low blood pressure following dinner on Sunday. Koko's health had been relatively stable before the last episode, and she had no declared chronic diseases recorded in her medical condition, which makes her death relatively sudden. Official documents indicate that Koko Stambulova was born on June 1, 1889, and lived through the reign of the last Russian Tsar Nicholas II, witnessed the 1917 Revolution, World War I (1914–1918), and World War II (1939–1945). Documentation experts note that verifying longevity requires precise birth records and continuous official certificates, which many people who lived in politically turbulent and administrative regions during the 19th century lack. The Chechen centenarian Koko Stambulova died at the age of 129 in her native village of Pratskoye in Chechnya. She also witnessed the collapse of the Soviet Union in 1991 and became a significant subject for researchers and historians interested in studying individuals who lived through more than a century of global transformations. Her registered age surpassed that of Jeanne Calment, the oldest recorded person in the Guinness Book of Records (122 years and 164 days).
