Well, it's straightforward in a way to tell someone with bipolar illness just to take their medication, but it's difficult to actually have them do it when they don't have insight. Some of the things you put around them in the mental health court are support workers, housing, help to solve some of the other stresses and problems. You help them develop an alliance and start to develop a sense that they can improve their lives, and then they start to include medications as part of it. I often will prescribe people medications that help them in some other way, such as helping their sleep, etc. Then gradually, as they get better, their insight will improve.
You're quite right that many people with bipolar disorder do very well, but there's also a small group who are difficult to treat. We can't get them to stay on their medications, and they often are using substances, so that there is a really vicious cycle in play.
