The Age of Adolescence

Just so we are all the same page, researchers have (re-)defined the period of adolescence from 10 to 25 years of age.  YIKES!!!!  Whatever happened to becoming a teenager when there was a "teen" at the end of your birthday - thirteen, sweet sixteen, nineteen.  Since when are 10 year olds, our innocent third or fourth graders, considered to be at risk for those crazy teen behaviors?  Thanks to brain scans and related technologies, researchers are marking a change in brain development that may start as early as 10 years old.  If you thought PUBERTY defined adolescence, then you may be even more surprised to hear that puberty, especially in girls, can start as early as 7 years old.

Similar brain scans and the same technologies show that the brain fully "matures" during a person's mid-20s.  Now, I know what you may be thinking: there are a lot of people older than 25 who aren't mature.  This may be true, and I may know some of the same people, but remember, we are talking brain development.
