The quote you've got is from a 2003 publication,
@shimmerz, and is not totally accurate anymore.
I don't want to derail the thread too much, so I'll just try and clarify.
Your experience with catatonia would probably be referring to the diagnosis of a Catatonia Specifier. Catatonia specifiers are seen with mood disorders, the bi-polar spectrum, and the schizophrenia spectrum. Basically, it's one of those symptoms that crosses through many other diagnoses, but it is a strong enough feature to get its own label.
In order to have "Catatonia Associated With Another Mental Disorder" (catatonia specifier), you need to meet
three of twelve criteria. They are:
Stupor, catalepsy, waxy flexibility, mutism, negativism, posturing, mannerism, stereotypy, agitation without external stimuli, grimacing, echolalia, and echopraxia.
From what you've described, it sounds like you displayed stupor, mutism, and probably negativism (basically, being non-responsive, but to an extreme degree)
The other two types of catatonia diagnosis are catatonic disorder due to another medical condition, and unspecified catatonia. "Another medical condition" means anything non-mental health related. That's where catatonia fits into the realm of general medicine.
An example of my point would be this: A person in (medical) shock will usually demonstrate stupor. They are also probably not speaking, but that doesn't mean they are displaying mutism. They may be non-responsive, but it's because they are occupied with the situation that caused the shock, not because they are displaying negativism.
I've jumped on my little soapbox in a few other threads involving catatonia, just because I figure, hey, knowledge is power - and there is a common mis-perception that stupor = catatonia. That's all. There could be someone out there freaking out because they think they were catatonic, when actually they were just extremely dissociated, say. And not many people connect agitation with catatonia, but when it shows up in a manic phase of bi-polar 1, (maybe along with grimacing, echolalia, and posturing), that's what's happening.
I'm absolutely
not saying that you (or others on this thread) were not catatonic. It's incredibly difficult to diagnose, actually, both from the outside and from being inside the experience of it. They are pretty clueless about what causes it, neurologically. The DSM V did a big overhaul of the whole thing, which had been a long time in coming, and it reflects a much more up-to-date understanding of the various symptoms and how they track through different disorders.
Argh, this is very long-winded (sorry!) - catatonia is sometimes the right word for what someone is going through, but sometimes it isn't. Being really "up" isn't necessarily mania, being sad isn't necessarily depression, a really intense, frightening experience isn't necessarily PTSD-grade trauma, and not moving or speaking isn't always catatonia.
Think of this as a catatonia infomercial :)
