In the USA ADD stands for Attention Deficit Disorder. I tried to google "Polyfragmented Attention Deficit Disorder" and could not find it. I looked in my Diagnostic Statistical Manual 4th Edition Text Revised and could not find it. Maybe its a listed mental disorder outside the USA either that or maybe the chart is out dated and no longer used for diagnostics here in the USA but was used at one time. in either case I was unable to find anything about Polyfragmented Attention Deficit Disorder. Ive had the same lack of luck in finding anything about Attention Deficit Disorder with features of Multiple Personality disorder there is no diagnostics on this particular label in the DSM IVTR and googling was no help. So again maybe its a diagnosis somewhere outside the USA or the chart is outdated and those diagnostic labels may no longer being used. now Im curious and would love to know more about these too so I will keep looking and will bring it up to my psych classes and see what comes of it.
