We're looking at the five symptoms of schizophrenia.
00:04
So when we say five symptoms of schizophrenia, we mean hallucinations, delusions, disorganized thinking, disorganized behavior, and negative symptoms, which i'll put over here, because this isn't just one symptom, this is a whole category.
00:45
So i've put these in two groups, because all of these first four fall under a group that we call b positive.
00:52
Symptoms.
00:56
So positive means it's the addition of something new to a person's behaviour, something they didn't have before.
01:03
Negative symptoms are the absence of something that a person would usually have.
01:08
So the negative symptoms first, things like poverty of speech, anhedonia, so a lack of pleasure, things like slowed movement, which at an extreme is catatonia.
01:28
So these are all negative.
01:29
Absence of things.
01:32
So we'll put those in a box on my own and look at the positive symptoms.
01:36
So these are also known as the psychotic symptoms.
01:39
These are the symptoms of psychosis.
01:45
So hallucinations, this is perceiving something without a stimulus.
01:52
So seeing something that isn't there, hearing something that isn't there.
01:57
So perception without stimulus.
02:09
A delusion is a fixed, false belief.
02:13
So the person believes something that is untrue, but you can prove to them it is untrue, but you cannot change their minds on it.
02:20
And these can be what we call non -bizarre, so they're possible, but so unlikely that the average person would not consider them seriously.
02:29
For example, you might believe that your psychiatrist is in league with your family and trying to sneak you antipsychotics at any point...
