There is that, though I'd consider little details like that to be worth including - it signals the readers that the LW has some clue what they're talking about (even if the readers don't know), and, in this case, could help educate readers about what Dr. Google considers an under-diagnosed condition. I mean, the Mayo Clinic page on diagnosis and treatment of IED is good reading regardless of if this is actually IED. I don't want people to self-diagnose from an advice column, but knowing that there are real conditions and treatments can be helpful.
