Why are the ’tween and early-teen years so hard on parents? It’s all in the brain, say medical researchers. Between ages 11 and 14, kids lose a significant portion of cell connections in the part of the brain that maintains alertness and enables good decision-making. The loss, say the scientists, is an essential part of growing up: It prunes “unneeded wiring” to make way for more efficient information-processing in adulthood.
