Developmental plasticity is highest between ages 0-25, after which rewiring the brain requires more intention and effort.

“It can be helpful to remember that the only (adaptive) neuroplasticity that occurs after age ~25 is self-directed-neuroplasticity.”

“And then somewhere about 25, it's not like the day after your 26th birthday, plasticity closes, there's a kind of tapering off of plasticity, and you need different mechanisms to engage plasticity as an adult.”

“The year 25, not the year 25, but rather, the age 25 years, is sort of an inflection point where the rigidity of the nervous system seems to really take off.”

“as you mentioned or alluded to the plasticity definitely goes down in older brains uh it it is harder for older people to learn new things to make radical changes in their behavior uh to you know kick habits that they've had for years”

“I mean everything I know about neuroplasticity is that it exists across the lifespan but that it tapers off significantly in one's late 20s right”

“takes a lot more to open that plasticity later than it does earlier certainly”

“a lot of what happens with the way people's lives play out as they get older have to do with their environment and their experience and that's not to say that I mean yes neuroplasticity does change as you get older but it doesn't account for the degree to which sometimes people can get stuck and set in their ways”

“we become more quote unquote set in our ways because neuroplasticity the ability to re reshape our neur neural circuits diminishes with age”
