Scientists believe they have discovered that new brain cells continue to develop in humans up to the age of 90.
As you get older, the hippocampus or the center of brain memory contracts, which helps to cause memory loss.
While some believe that the growth of brain memory cells stops after childhood, the new study suggests that the brain regenerates well in later years.
Scientists have found evidence of brain cell growth in the "hippocampus" region in individuals aged 43 to 97 years.
Interestingly, people with Alzheimer's disease have fewer new brain cells, even at the beginning of the disease, before other brain changes do occur.
"When people lose brain cells as they age, they can generate new cells to replace them," said Dr. Maria Lorenz-Martin, who led the study of the Center for Molecular Biology (CBMSO) in Spain. New brain ".
"If we can confirm these results in patients, this could pave the way for a future test of Alzheimer's disease, a drug for treatment or a lifestyle counseling," she said. declared.
A study conducted last year revealed that new brain cells, or neurons, located in the brain memory zone do not exist or are very rare in the adult.
The authors of the study, from the University of Southern California in San Francisco, have stated that these brain cells can not be discovered at puberty.
