You may want to check out the answers to this question to get some idea of the range of experiences bipolar folk have when manic.
If the guy is off his meds, he’s a severe suicide risk when he crashes. 20% of bipolar folks die of the disease (by their own hand).
Why off meds? Hundreds of reasons. Maybe they can’t afford them. Maybe they don’t have any left. Maybe their prescription has run out. Maybe they forgot one day, and decided not to bother. Maybe they think they can do without them. Maybe they believe they can control themselves using coping techniques. Maybe they want to be manic.
But the primary reason for not taking meds is the side effects. I am going back on Lithium as we speak because I’m getting a bit manic. I hate, hate HATE lithium! My fingers shake. I get constipated. I get skin rashes that never go away. There are a few others, too, that bother me. And, of course, I don’t really like the idea that eventually, it will require me to get new kidneys.
Other mood stabilizers and anti-depressants can make you groggy, or lower your libido, and many other things. The meds pretty much suck.
Of course, when you’re manic, most folks tend to become much more impulsive and angry. Put those two together, and you’re likely to see a lot more aggressive behavior. Some people get paranoid and others have hallucinations. They might think that everyone is trying to get over on them. They accuse people of ridiculous shit. Some even black out and when they come to, the room is a mess, or they’re in jail, and they have no idea what happened.
I’m sure you deal with a lot of liars and lowlifes, but my guess is you can soon tell if a guy really is bipolar or just garden variety violent. The fast speech and disorganized thinking should be a tip off. They should be even more hair trigger than your other inmates.
And they will crash sometime. They will think they are worthless and awful, and they will want to die. And if they are in prison, my guess is that they probably will die, because no one really gives a shit if a prisoner tries to kill himself. Anyway, let me know if I’m right.
