The areas involved in thinking, attention and planning mature an average of 3 years later than non-ADHD brains. The outer layer of the ADHD brain matures at age 10½ while the non-ADHD brain matures at 7½. The most serious lag is in the prefrontal cortex, the area behind the forehead, where executive functioning skills come from.
Executive functioning includes monitoring thinking, planning and organizing, managing time and materials, shifting gears, refraining from saying and doing inappropriate things, starting tasks and using working memory.
While the thinking parts of the brain develop slowly, the motor areas develop quickly resulting in restlessness.
The cases of ADHD are increasing globally and one-third of children continue to have symptoms into adulthood.
The more you know, the smoother it will go.
