Most, including myself, would argue that, particularly without treatment, bipolar disorder is a decrease in functioning. Untreated depression and mania disrupt every part of a life in negative ways – that’s what drives people to get treatment in the first place. But if bipolar disorder is an illness and is a decrease in functioning, why hasn’t evolution naturally selected out bipolar disorder? Why do we still see bipolar disorder today?

Bipolar disorder is associated with extremely high (mania/hypomania) and low (depressed) moods. This is typically seen with emotional changes, behavioral changes, energy changes and so on. Psychosis, on the other hand is the presence of delusions and hallucinations. Delusions – false beliefs that persist in spite of the existence of contrary evidence – and hallucinations are most closely associated with schizophrenia. However, symptoms of psychosis can occur in bipolar disorder and depression as well.

There is a persistent myth that having bipolar disorder means you have a “broken identity,” or even, “split personality.” I would imagine the term “manic depression” (an older term for bipolar disorder) conjures up these images for some people. But I’m here to tell you, my identity is just fine as is my personality.

Last night I drank. Alcohol. OK. You probably don't need to alert the media. But I do need to alert you about the horrible effects alcohol can have on a person with bipolar disorder.

Yes, psychiatric drugs can cause weight gain. It's not a rumor; it's not a myth; it's true. It's one of the most unfortunate things about medication. But what can you do about drug-related weight gain?

As I work, I battle the stigma around mental illness. It feels like often, all day, every day, it's the only thing I do. But I do it because I feel it's important. I feel it matters. I feel it changes people's lives. And one of the misconceptions I've heard multiple times recently is about bipolar and mental illness diagnosis. That by accepting a diagnosis of a mental illness this somehow removes the responsibility from the individual for their own wellness. That, somehow, a mental illness diagnosis makes the patient weak because now they are looking for someone to "save" them or "cure" them. Well nothing could be farther from the truth. Getting a mental illness diagnosis is only the first step in what a patient must do in order to recover.

Today I was made aware of a site that went up specifically to make fun of, and show hatred towards, those with bipolar disorder. Specifically, the site is aimed at me and all those who use psychiatric services in the treatment of mental illness. Whoever wrote the site feels it's okay to take advantage of people with an illness, people who are in pain. Well, it's not OK. We're not a joke. We are people. Real, flesh and blood people. And we do not accept your hatred. I do not accept your hatred.

I don't have anything against people with a disability. Why would I? Being disabled means nothing about the individual, it simply indicates their situation. It would be like being against people with siblings. It would just be silly. Nevertheless, when considering my own bipolar disorder, I bristled against the word "disability." I know; this is hypocritical of me and a double standard. It's OK for someone else to be disabled but not me? I'm embarrassed to even think it. But bristle I have and think it I (mostly subconsciously) did. The truth is, though, I'm a person with a disability.

Bipolar disorder is an affective disorder, in other words it affects your emotions (among other things). Bipolar disorder symptoms are often about feelings. Well, they're about FEELINGS. I feel HAPPY. I feel SAD. I feel IRRITATED. I feel ENERGETIC. But one thing that's rarely recognized is that sometimes bipolar disorder is about feeling nothing at all.

I've been studying mental illness for a long time and while I knew the answer to this question, I couldn't really have told you why. This is mostly because I haven't done a lot of work on personality disorders, but I have had occasion to learn more about them recently. No, bipolar disorder is not a personality disorder, and here's why.
