Hi,
The definitive journal article on the existence of ADHD is:
International Consensus on ADHD Statement
January 2002
Published in the Clinical and Family Psychology Review,Vol.5,No.2,June 2002,89-111.
That article is signed off on by over 80 of the world's leading scientists from all over the globe. The lenght of the article is due to the 14 1/2 pages of scientific references, which represents one of the most definitive reference lists available today.
But wait, because I'm not thru with your professor.Not by a long shot. Here's the landmark journal aticle on the discovery of the gene marker for ADHD ( and btw, ALL these references have been peer reviewed, so I don't want to hear that lame crap for an excuse not to read it remark) Here it is in APA format:
Cook,E.H.,Jr,Stein,M.A.,Krasowski,M.D.,Cox,N.J.,Olkon,D.M.Kieffer,J.E.,& Leventhal,B.L.(1995).Association of attention-deficit disorder and the dopamine transporter gene.American Journal of Human Genetics,36,993-998.
Just in case your prof doesnt have the time to look it up, the article noted the finding of a dopamine receptor gene (DRD) on chromosome 11 and the dopamine transporter gene ( DAT1) on chromosme 5.Since then, a variation of DRD (DRD4) has proven more stable to work with.In addition, another gene has been isolated(DBH-Taq1), as well as an area strongly suspected of being inolved(16p13 region).
Cook et. al.(1995) was featured in a Chicago Tribune article by Peter Gorner in May of 1995.
The International Consensus Article should be on Russell Barkley's website.
The genetics article is important because it helps confirm what has been referred to as the " Dopamine hypothesis," which is really an off shoot of the Biogenic Amine Hypothesis. Here's what thats all about and why it slam dunks your prof and all those too lazy to read any of the 6k+ journal articles, professional papers and books on the most widely researched childhood disorder on planet earth(ADHD)
The Biogenic Amine Hypothesis is the concept that abnormalities in the physiology and metabloism of biogenic amines, particulary catecholamines( norepinephrine and dopamine) and indoleamines(serotonin), are involved in the causes and courses of certain psychiatric illnesses.
The concept was derived originally from a serendipitious discovery that monoamine oxidase inhibitors and certain tricyclic drugs had mood elevating properties, and that these agents exerted dramatic effects on brain monamine functions.
Here's why thats important. That discovery paved the way for the development of the SSRI class of antidepressants we all are familiar with today. When it was united with an earlier discovery from 1911, Erlich's Side Chain Theory, which was the forerunner of what we now call receptor sites; the SSRI's were born.
The bottom line on this is that if ADHD isnt real, then neither is depression. bipolar mood disorders, OCD, Tourette's etc. They are all linked via the Biogenic Amine Hypothesis(and before someone jumps up and down shouting " its just an hypothesis", the fact that ADHD meds work at all proves the theory).
The other thing that so called "walking paradoxes" as I call them (simultaneously arrogant & ignorant), forget to consider is this: before you can say a disorder isnt real, that implies YOU KNOW what a REAL disorder is. How else could you tell the difference?
ADHD meets the criteria for a Disorder as outlined by Rutger's researcher Jerome Wakefield:
Wakefield,J.C.(1999).Evolutionary versus prototype analyses of the concept of a disorder.Journal of Abnormal Psychology,108,374 - 399.
I really haven't even scratched the surface here but I am very pleased you came in and asked that question. I appreciate it and wish you luck in your studies. If you have more questions or just want to see another tomahawk slam dunk, please don't hesitate to ask us.
Your professor will never know what these incredible parents have (and still are) going thru with their equally incredible children. I am in awe of them and what they do and sacrifice for their kids evey day. So when someone comes along and has the audacity to shoot their mouth off without doing their homework, I then take it personally, as I am an adult ADHD age 53, diagnosed in 1972 with the Halstead - Reitan Neuropsych battery.
Thanks again and good luck with your studies:)
Take care.
