ADHD has a high prevalence in my family; all of my nuclear family has now been diagnosed with ADHD symptoms, but as of 5 years ago, my younger brother was the only person with disruptive behavior and, as such, at 12 he was the only one diagnosed and medicated. Though this seems positive, the message he received when medicated was, "there is something
wrong with you and you need this medicine to fix it." Most 12 year olds do not have the coping skills to deal with this, especially when ADHD intensifies emotions. He is struggling with self-worth issues at the moment, and he is 17.
In contrast, I went through high school with undiagnosed ADHD, and though it was difficult, I never once felt that there was something
wrong with me. Different maybe, but not wrong.
Because my self worth was never challenged, I believe, I could push through what were often excruciatingly difficult situations because I thought I could. I graduated in the top 10% of my high school; I went to an incredibly prestigious college, and am now a teaching fellow in a very very competitive program. I have been identified by many as a "high achiever."
I have esteem issues, as most people with disorders do, but the fact that I recognized my difficulties as an adult and sought my own diagnosis and treatment makes medication and therapy empowering. I finally have answers to why many activities were so hard growing up.
I do not think I would have done well if I had been "diagnosed" (or told that I needed medication) when I was younger. Children with ADHD receive messages louder and often in different ways than we may intend to send them.
Teach your child the skills that will lead them to success. Give them organization systems (which I learned from friends when I got to college; during the tough times, I wrote the directions to simple tasks like getting ready in the morning or how to take notes on lists and posted them to the front of doors and folders so I would see them when I did that task). Teach them to use their watch; teach them the purpose for the computer and how it can be beneficial but also very destructive to productivity.
And be honest, many things will be more difficult for them than others, but with ADHD they have an unrestricted flow of creative ideas, something very very few people have. Many successful people are successful because of this disorder including the CEO of JetBlue airlines (he's written many articles on the subject). Many historical artists, including a large quantity of poets, painters and sculptors couldn't have completed what they did without the "hyperfocus" that comes with ADHD.
