I would like to bring up suspicion in the area of ADHD.I may be wrong but someone like myself who has ADD and a brother with ADD and CHRONIC DEPRESSION went down different paths in life.I'm not sure i believe in ADHD-is it not just ADD with DEPRESSION? Does not depression increase anxiety greatly making it appear as a part of ADD,making doctors call it ADHD.My anxiety was manageable and i didn't engage in drug use,but my brother did.Maybe i'm different and there are versions of ADD. Are not stimulants a great help for depression as you mentioned in LISTENING TO PROZAC And antidepressants helpful for ADD.My emotions changed very little if any with the antidepressant i tried,but my anxiety greatly improved.My thoughts were too sluggish and i had to discontinue it.I tried and i'm still taking strattera which again helped my anxiety and gave me more concentration and mental agility later in the day. unfortunately it has done little for my memory and has made it a little worse,so i could probably use a stimulant now that my anxiety is down.I'm not flying a commercial plane so i'm fine for now.My concern is the blurring of ADD and ADD with depression.I do hope you address ADD in the future and of course would love to here what you have to say. Great article on ethics which also dominate your books. my best to you, David Petropoulos
