Hi L.,
Before you jump on the ADHD bandwagon, there are things you can do to get you to a baseline of health so that, whatever the diagnosis, it will be accurate. The abundance of synthetic chemicals in our bodies do weird things to us and they contraindicate just like pharmaceuticals do...once you pile more and more in your system the contraindications just go haywire. I recommend a detox of your body and your home. Once the chemicals are actually gone, then retake your test.
My daughter was diagnosed with ADHD and it turned out it was simply chemical toxicity. Laundry detergent, window cleaner, bath soap, and even McDonald's hamburgers (with their pesticides, preservatives, antibiotics and hormone) were simply wreaking havoc on her system.
There is no way that this condition can not be man made. When I was a girl, there was maybe one class clown in the entire grade. Now, everyone is medicated because they can't sit still and they have to speak to everything.
This is just a thought. It helped so much in our home and has made my life and my little girl's life so much easier and happier. If you're interested in how I did what I did, private message me and I'll walk you through it.
God bless,
M.
