how it could affect health

Scientists monitored the increase in brain volume of people born between 1930 and 1970.
As part of the study, scientists compared MRI results of residents of the city of Framingham, Massachusetts. The final sample consisted of 3226 people, 53% of whom were female.
As informs Med Page Today with reference to researchthe results showed an increase:
- intracranial volume by 6.6%;
- the volume of white matter by 7.7%;
- hippocampus volume by 5.7%;
- surface area of the cerebral cortex – 14.9%.
However, an increase in the total volume of gray matter was not detected.
The scientists hypothesized that such changes could potentially lead to “brain development and increased brain reserves,” which could contribute to lower rates of stroke, Alzheimer’s disease, and dementia.
Also, researchers do not rule out a positive effect on cognitive stability.
“The decade in which a person is born appears to influence brain size and potentially long-term health.
Genetics play an important role in determining brain size, but our findings show that external influences such as health, social, cultural and educational factors may also play a role.”– says the co-author of the study, Charles Decarly, about the possible factors of such changes.
It is currently not clear how an increase in brain size can affect a person’s health. However, scientists say that adult brain volume is “an important indicator of cognitive function in old age.”

We will remind, previously South Korean scientists investigated the effect of interaction with dogs on the human brain.
