00:01
So the patient has been running the streets in the nude talking to himself.
00:05
He's experiencing delusions and hallucinations and has high amounts of fensiclidine in his system.
00:12
Could he be diagnosed with? fenceclidine -induced psychotic disorder.
00:17
Psychotic disorder due to a general medical condition, schizophrenia or brief psychotic disorder.
00:24
So delusions, hallucinations, it's fair to say the patient is experiencing psychosis.
00:30
What would be the diagnosis? well, the first thing we have to look at is how long has this been happening for? how long are symptoms present? because one of these, schizophrenia, they have to have been present for at least six months.
00:46
So we cannot diagnose schizophrenia.
00:49
It's just not been long enough.
00:52
Okay.
00:53
Next is why is the psychosis happening? and fencecladine can cause psychosis.
00:59
So we would not say it is a brief psychosis.
01:02
Disorder because for a brief psychotic disorder, there can't be another cause.
01:07
Cannot be another course...
