Brain aging is inevitable to some extent, but not uniform; it affects everyone, or every brain, differently. Slowing down brain aging or stopping it altogether would be the ultimate elixir to achieve eternal youth. Is brain aging a slippery slope that we need to accept? Or are there steps we can take to reduce the rate of decline?
At around 3 pounds in weight, the human brain is a staggering feat of engineering with around 100 billion neurons interconnected via trillions of synapses. Throughout our lifetime our brain changes more than any other part of our body. From the moment the brain begins to develop in the third week of gestation to old age, its complex structures and functions are changing, networks and pathways connecting and severing.
