I just don't get why Aspergers is categorized as a mental illness. It's in the Diagnostic and Statistical Manual, so it must be, but I still don't get it. I "get" why schizophrenia is considered a mental illness, although I don't agree with labelling it as such. It's all so confusing, really.
Here's a story from the Ottawa Citizen about a mother who is not able to hospitalize her son because the Asperger beds are full, but there are spaces at the hospital if you fall under another mental illness category. Note that Aspergers used to be something rare. Now, by bed count alone, it appears to have overtaken traditional "mental illnesses" like schizophrenia in a spectacularly short period of time.
The real reason for being admitted to mental health facility may simply be that your family can't deal with your behavior any longer. In the absence of helping the whole family find a better way of coping, the one with the label gets time out in the institution and the ones without the label get time out at home.
