According to a Danish research, mental performance is better in today's 90-year-olds who are surviving into very old age. The research revealed that people born in 1915 scored higher in cognitive tests in their 90s in comparison to people born in a decade earlier.
The study was published in the journal The Lancet. Experts pointed better living standards and intellectual stimulation for being the key factors. According to the study, there is a global rise in the number of people reaching very old age.
Number of people aged 90 or above has more than doubled in 30 years in the U. S. The study was conducted in Denmark. It suggested that likelihood of surviving into the 10th decade of life has gone up by around 30% each decade for people born in 1895, 1905 and 1915.
The research did not focus on the quality of life of people reaching such an old age. The study was led by Prof. Kaare Christensen, of the University of Southern Denmark in Odense. The study involved all Danes born in 1905 who were alive and living in the country in 1998.
Prof. Christensen and colleagues said, "This finding suggests that more people are living to older ages with better overall functioning".
