Link Removed and Link Removed - hmmm, not really opined much on the term "disorder" itself. Reviewing my hospital file from beforehand the Doctors were contemplating whether in addition to "depression" I also had either borderline personality traits v. narcissistic personality traits...(this was upsetting) - these are considered personality "disorders" - is this what you mean, or something else?
A disorder is the entire constellation of symptoms making up the whole. It's a unique and discrete thing made up of many different moving parts. The symptoms, on the other hand, are shared with other disorders, or can exist as a stand alone thing, themselves.
A short / wildly incomplete list of disorders to example : Acute Stress Disorder, Adjustment Disorder, Affective Disorders (mood disorders), Amnestic Disorders, Anxiety Disorders, Attention Deficit Hyperactivity Disorder, Behavior Disorders, Binge Eating Disorder, Bipolar Disorder, Body Dysmorphic Disorder.... et cetera. Serious etc. I'm still in the B's!
One of the places where people get really screwed up is they have XYZ symptoms, so then they think they have ______ disorder. Like they have anxiety, so they "must" have GAD. Or they have trauma, so they "must" have PTSD.
Nope. Not the case. Anxiety exists as a
symptom in a few dozen disorders, as well as a stand alone disorder in and of itself (with other symptoms in its constellation). Trauma, meanwhile is a part of many disorders, as well. Not just PTSD.
One way to help visualize these things is with cooking.
Disorder = Meal
Symptoms & Traits = Ingredients.
You may have wheat, tomatoes, cheese, olive oil, herbs. But how they combine? Extremely important. You may have pasta or pizza or bruschetta with those ingredients. All 3 of those meals contain the same ingredients / share symptoms. And all 3 of those meals can exist alone, or exist together (comorbid). But just because you have the ingredients, it doesn't mean that you have all the meals. Same token, if you have Pizza? It's redundant to say you have wheat, tomatoes, cheese, olive oil, & herbs. If you have pizza? Yeah. You've got those things. That's part of having pizza! To be comorbid, there has to be a whole other thing in addition to your pizza.
