Affected children have trouble concentrating and behaving in class.
However, I believe that this disease has become a crutch for lazy parents looking for a way to avoid truely raising their children. I did not expect them to be perfect little adults all of the time, so of course they all encountered some discipline problems. I really noticed no change in the children's attitudes and personalities when they missed their medication. Of course you kid will have symptoms of ADHD if you do not positively reinforce good behaviors and punish bad ones, because they won't listen to a damn word you say. In conclusion, parents need to stop muting their children's personalities with mind deadening drugs and do their jobs.
