Adolescent Mental Health Inpatient Units

Do you think her behaviour is deteriorating because she's in the facility?  Or was it going the same way before she was admitted?

I confess to knowing nothing about conversion disorder, I'd never heard of it.  So I looked it up, here are a couple of snippets from Wikipedia:

"Formerly known as "hysteria"...

The DSM-IV classifies conversion disorder as a somatoform disorder while the ICD-10 classifies it as a dissociative disorder.

Prognosis

The DSM-IV-TR states that conversion symptoms will in most cases disappear within 2 weeks in those hospitalized. One-fifth to one-quarter will have a recurrence within a year with this also predicting future recurrences. Acute onset, clearly identifiable stress at this time, and short time between onset and treatment are associated with a favorable prognosis.

Conversion disorder presents with symptoms that typically resemble a neurological disorder such as stroke, multiple sclerosis, epilepsy or hypokalemic periodic paralysis. The neurologist must carefully exclude neurological disease, through examination and appropriate investigations.[18] However, it is not uncommon for patients with neurological disease to also have conversion disorder.[19]

In excluding neurological disease, the neurologist has traditionally relied partly on the presence of positive signs of conversion disorder — certain aspects of the presentation that were thought to be rare in neurological disease, but common in conversion. The validity of many of these signs has been questioned, however, by a study showing that they also occurred in neurological disease.[20] "

Misdiagnosis is apparently at a rate of 4%.  I will do a little more research.
