What to do about attention deficit disorder?

The Golden Child asked:


I have a chronic attention deficit problem. I cannot concentrate for more than a few seconds. I cannot remember what I did a few hours ago. Today I day dreamed through my train station and ended up further than I intended to go. If I drive somewhere I cannot remember how I got there. I forget everything. I walk out of meetings and I cannot remember what was said. It’s beginning to seriously impede my career. Is there anything that can be done about this?
