Hi there,
Maybe take a look at
"Disorders" section, click on and you'll find definitions for the various disorders.
"Disorders" section is above the word "Forums", near the upper left hand side.
Hope this has been of help to you. Both disorders are not the same, but some behaviours/traits can be similar, it's also possible for a person to have more than one disorder, so I think it's important that your pdoc talks with you about this, and be sure that you ask any questions you have about the DXes and treatments possible.
Lots of luck with this, take care.
