What happens in the brain after 40 years?

He brain aging It is a natural process that affects all people over time. As we age, our brains undergo structural and functional changes that can affect our cognitive abilities and information processing, as well as in motor functions.

The website of National Library of Medicine explains that as people age, the brain and nervous system undergo natural changes such as reductions in thinking, memory and cognitive abilities.

What happens in the brain after 40?

The site of National Geographic explains that after the age of 40 people present changes in the vascularization of the brain, in its size and in cognitive processes.

AS As the years pass, the brain reduces in size and on average it loses 5% of its volume every ten years. The part most affected is the frontal lobe, responsible for speech, behavior, attention and executive functions.

This happens because with weight loss in the brain and spinal cord, neurons transmit messages more slowly than when the person was young.

however, the Cerebral atrophy It not only impacts cognitive abilities, but also physical functions, because hormones not only control thoughts but are also responsible for sending nerve impulses to move and coordinate the muscles of the body.

This would explain, among other things, why older people walk and move more slowly, tend to have memory problems and their ability to think is reduced.

Although there are mechanisms to counteract this difficulty, if the hormones are performing their functions correctly, the urge may not be intense enough to trigger it.

For reduce the degradation of the nervous system, The most effective thing, in addition to following a balanced diet and sleeping the hours necessary for proper rest, is to perform resistance exercises. These increase muscle strength, stimulate motor neurons, and help neuron-driven physical functions continue to function.
