My friend described his ADD as like a crystal ball at the disco, you know with the multitudes of glittering silver squares. He said when he was asked something, eg A teacher said, "Stop doing that" he got confused because he had all these images in his head and didn't know which one to stop. Stop thinking about the weather? Stop thinking about his girlfriend? Stop thinking about whatever?
Over the years he has learned to deal with it.He said many people see it as a problem, he now describes it as his unique way of doing things. He said he has turned his "problem" into an asset.
The incentive for him was finding out that his children have ADD. He is now a specialist in treating children with many learning disorders, from ADD to Autism of all types. He has had success where many psychiatrists and other specialists have failed.
One of the techniques he uses, such as turning 'weaknesses' into strengths is working very well. For example, many autistic children are kinethetic, and when teaching them to read/write he uses playdo and gets them to make each letter of the alphabet with their hands. He then gets them to stand above, below and to each side of the letter as it sits on the ground and asks the to "Feel the letter". Sounds strange I know, but it works.
Enough of my ramblings, I could go on forever, I've probably the lot of you. Sorry.
