Scientists believe they have discovered that new brain cells continue to develop in humans up to the age of 90. With age, the hippocampus or the center of brain memory narrows, which helps to cause forgetfulness.Some believe that the growth of brain memory cells stops after childhood, Suggests that the brain regenerates well during the course of time. last years of life.
Scientists have found evidence of brain cell growth in the "hippocampus" region in individuals aged 43 to 97 years, and it is worth noting that patients with the disease of Alzheimer's have fewer new brain cells, even in the early stages of the disease, before other brain changes. .

"These results suggest that when people lose brain cells as they age, they can generate new cells to replace them," said Maria Lorenz-Martin, director of the Center for Molecular Biology (CBMSO) in Spain. "This opens the possibility of generating new memories with the help of brain cells.
"If we can confirm these results in patients, this could pave the way for a future Alzheimer's disease test, drug treatment or lifestyle counseling," he said. she 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, said that these brain cells could not be discovered at puberty, but Spanish scientists claim in the new study that the Proteins produced by the development of brain cells could have been "hidden" by scientists after they were mixed with chemicals stored in brain banks.
The research team discovered "thousands" of developing brain cells in memory centers in 13 people aged 43 to 87 years old.
The study, published in the journal Nature Medicine, tracks the brain analysis of 45 people aged 52 to 97 years at different stages of Alzheimer's disease.
