The aging brain does not decline, but rather undergoes a new process of adaptation
A study by US neuroscientists showed that memory changes in old age are not brain decline, but rather the brain restructuring itself to use experiences efficiently.
Scientists from the University of Arizona in America have revealed that memory changes in advanced age do not mean a decline of the brain, but rather that it reorganizes itself to use accumulated experiences more efficiently.
Refuting the Traditional Thesis
The research completely refuted the thesis, long defended by traditional neuroscience circles, that old age is a period of compensation and decline.
Similar Neurological Leaps
Scientists examined this process by stating that a similar neurological leap to that seen in childhood also takes place in advanced ages.
Adaptive Development Stage
The research demonstrated that aging is not a loss of mental capacity, but rather a genetically conserved adaptive development stage.
Task Shift in Brain Regions
As people age, while the hippocampus steps into the background, the prefrontal cortex, which processes general knowledge and experiences, takes over control and uses resources sparingly.
Strengthening of Synaptic Networks
In old age, some neural connections and synaptic networks, instead of weakening, grow significantly stronger to form a new order of priorities.
Expert Opinion and Objectives
Psychologist Fabian-Xose Fernandez made important evaluations, emphasizing that the aging brain is optimized for the sharing of stored expertise.
Contribution to Alzheimer's Diagnosis
Clarifying this adaptation strategy will enable the biological symptoms of Alzheimer's disease to be distinguished from the normal aging process much earlier.
