I’ve been wanting to write about evidence that bipolar disorder type II really is bipolar disorder and really does exist. Why? Because some very vocal people have attacked me on this point. There is this ridiculous notion that bipolar disorder type II is made up just to sell more drugs and that I am pushing this evil agenda. But, well, I just haven’t had time to get the facts and evidence together for you. So today I just want to speak from my own experience — I have bipolar disorder type II and yes, it is real bipolar disorder.

What Is Bipolar Disorder Type II?

Many people don’t know the difference between bipolar disorder type I and type II. For more on this, please see this article. In short, people with bipolar disorder type I experience mania — a more severely elevated state than people with bipolar disorder type II. People with bipolar type II experience hypomania, which has all the same symptoms but it less severe.

It should also be noted that psychosis (the presence of delusions and/or hallucinations) can be present in bipolar type I and not in type II and those with type I do tend to require more hospitalizations in their elevated periods due to the severity of their manias.

So, I’d like to reiterate that: people with bipolar disorder type I and type II have all the same diagnostic symptoms with a difference in severity of mania (psychosis isn’t a diagnostic symptom either way).

Bipolar Disorder Type I Is the ‘Real’ Bipolar Disorder

Look, bipolar disorder type I can be considered “classic” bipolar disorder (or manic depression, if you really prefer). But that doesn’t make it more “real.” People with bipolar disorder type I have very real experiences and in some ways, they can be different from those with type II but in most ways, they are actually the same. More links bipolar disorder type I and II than separates them, certainly.

Why Does Bipolar Disorder Type II Even Exist?

I have bipolar disorder type II and while bipolar type II is different than type I, that doesn't mean bipolar type II is any less real. There’s a reason why bipolar disorder type II exists — and no, it isn’t to sell more drugs. It exists because people with bipolar disorder type II have an illness that clearly contains major depressive disorder but responds differently to treatment than major depressive disorder alone does. When you have a person with major depressive disorder and you give them an antidepressant, they tend to improve. When you give an antidepressant to a person with bipolar disorder (type I or II) they will often get worse in that they will flip to mania/hypomania, a mixed state, cycle or even become psychotic. Antidepressants can worsen the course of bipolar disorder over time whereas for major depressive disorder, they improve it.

Treatment wise it is extremely important to understand these differences and understand these differences do warrant another diagnosis. Bipolar disorder type II is like major depressive disorder plus. Bipolar disorder type I is like major depressive disorder plus too. In the case of bipolar I, it’s plus mania. In the case of type II, it’s plus hypomania. That makes them awfully, awfully similar.

So the diagnosis of bipolar disorder type II is important because not only does it characterize the experience of the illness but it also indicates proper treatment. (And while treatment for bipolar disorder is nuanced, it can simply be put that bipolar disorder type I and bipolar disorder type II are treated almost identically.)

Bipolar Disorder Type II Is ‘Real’ Bipolar Disorder

Look, I have bipolar disorder type II and I know how similar my experience is to those with bipolar disorder type I and I know that we do, in fact, have very similar illnesses. But you don’t have to believe me.

What you should believe, though, is that people with bipolar disorder type II, like me, clearly have a serious mental illness no matter what you call it. And from my perspective, you could call it “Fred.” I don’t care. That doesn’t change the illness and it doesn’t change the treatment necessary. If that makes you feel better and that makes you feel like I’m not encroaching upon your precious bipolar disorder diagnosis then, sure, I’ll say I have Fred. Sure, you have the “real” bipolar disorder and I have Fred. Feel better?
