A new study conducted in China revealed that individuals who have a biological age compared to their age are more likely to develop dementia by up to 30%.
Biological age increases the risk of dementia by 30%
According to Sinas Live, the time age is measured by the number of years from birth, while the biological age is determined based on the general health status and age indicators inside the body, which sometimes makes it older or younger than time age.
The study relied on analyzing healthy data for more than 280,000 participants from the British Biological Bank, with an average age of 57 years, and none of them had dementia at the start of the study.
Follow -up continued for 14 years, as researchers used vital indicators such as lung function, blood pressure, cholesterol level, the number of white blood cells, etc., to calculate the biological life of the participants.
The results showed individuals belonging to the higher biological age group were more likely to develop dementia compared to their smaller biological peers, as it was observed that there are changes in the brains of these participants, most notably the decrease in the size of the gray matter, which is the area responsible for processing information and cognitive and motor functions.
Previous research indicated that the loss of gray matter is related to an increase in the risk of Alzheimer’s disease, which supports the results of this new study and stresses the importance of preserving biological health as a preventive factor against mental deterioration.
