For many of us, our memories seem to get worse a little every year that passes. It starts with being unable to remember if you have locked the door or disconnect your hair dryer, then you find yourself forgetting the appointments or the name of a new knowledge. But even if we are led to believe that it is a universal experience, there are people whose memories remain clear even as they age. These "super -agents" seem to remember everything at 80 - and science shows that they have a few things in common.

In relation: These 5 daily habits can reduce the risk of dementia, show new research .

Published research In The Journal of Neuroscience yesterday and a company study Published in Lancet healthy longevity In August 2023, examined 119 participants over 79.5 years old in Spain. Fifty-five were typical older adults, while 64 were classified as "super-agents" or those who have "the memory capacity of people aged 30".

Participants spent three non -memory tests and a memory test (the free and indicated selective recall test). They were classified as super-agents if they obtained a score above the average score for 50 to 56 year olds during the memory test, and around or above the average of their age on non-memory tests .

It turned out that super-agers had similar appearance brains. Overall, they had less brain atrophy (Loss of neurons and connections between them) only typical elderly people, especially in "memory -related areas" like the hippocampus, have shown MRI analyzes. Super-agents had specifically better quality white substance at the front of the brain, which is a region that plays a role in cognition.

In particular, typical super-agents and adults had no difference in terms of genetic risk factors for Alzheimer's disease.

"By having two groups which have low levels of Alzheimer's markers, but striking cognitive differences and striking differences in their brains, so we really speak to a Age -related decline resistance , "Author of the main study Bryan Odd , CTP, UPM, professor of clinical neuroscience at the University of Polytechnic in Madrid, said The New York Times .

In relation: The longevity expert says it is to avoid eating the "toxic 5 ps" if you want to live at 100 .

Experts do not know how many super-agents exist, although Emilie Rogalski , PHD, professor of neurology at the University of Chicago, told Nyt that they are "relatively rare". (Rogalski managed his Super-agents search In 2012, noting that these elderly people had a brain that looked like those from 50 to 60 years old.)

How people become super-agents is not either, Tessa Harison , an assistant project scientist at the University of California in Berkeley, who worked with Rogalski in the 2012 study, told the Nyt . But she suggested that super-agents can simply have "a kind of lucky predisposition" or "brain resistance mechanism" that scientists do not yet understand.

Speaking to that, Strange said to Nyt That typical super-agents and adults also had similarities in terms of diet, sleep habits, professional environments and alcohol and tobacco consumption. However, super-agers are distinguished in what they had better mental health and moved faster than the average elderly. (While super-agents have reported a frequency of exercise similar to their "typical" counterparts, the researchers have hypothesized that they can engage in a more "not exercised" physical activity, like climbing stairs or gardening.)

Despite this, there was also the consistency that vacillates in the super-ages group. Although they all had exceptional memories, the super-agents of the study of Rogalski diffracted in the frequency to which they did the exercise, the health of their diet and if they smoked. Solid social relations, however, were something they had in common.

If you want to improve your chances of maintaining a healthy brain, experts recommend keeping your diet under control, exercising, keeping your social life and sleeping enough Nyt reported.
