Does our brain go through a remodeling during teenage years? Yes. Absolutely.
Our brain keeps making new cells and remodel pathways for balance, memory, and emotional control during early childhood. The last set of pruning, updating, and renovation of these neuronal pathways happen during teenage years.
These substantial changes in the brain structure account for why teenagers may experience turmoil in their behavior and do things that don’t always make sense. Once these changes our completed, our brains are in top notch condition in our 20s.
Beyond that, our brain maintains its ability for plasticity and repair; it changes for better or for worse, but not to the same degree that happens in our teenage years.
Given that anatomical changes happen to the brains of teenagers, we (as parents) need to be patient with them. We need to allow them to find their new pathways in life and guide them to make good decisions.
Also, we need to help them eat well, sleep well, and exercise a lot. And of course, we should help them avoid concussions or drug abuse.
