Scientists from University College London have revealed the secret to the fight against senile dementia, PLOS Medicine reported.

According to the study, old people, aged from 50 to 60 should lead a socially active lifestyle and spend their time with their friends more often.

As part of the study, scientists observed 10 thousand volunteers for 30 years. It turned out that those who was out with their friends almost daily, had a 12% lower risk of developing dementia compared to those who led a less socially active life.

A link was also established between social exclusion and memory problems.
