- [Instructor] Schizophrenia is a disorder of the brain.

Adverbs of degree

it has nothing to do with multiple personalities.

about things that can cause schizophrenia

and there are likely to be many different causes,

but we know that it's likely to be a combination

of genetics and environmental causes that will be at play,

and when I say environmental, that may include things

and also growing up, childhood experiences,

so it's really a combination of these two big factors

that leads to abnormalities in the brain,

and these abnormalities in the brain can actually

be picked up by some of the tests that we have today.

Some of our brain imaging tests can show some

abnormal changes in some individuals with schizophrenia.

We know that some of the neurotransmitters,

the brain chemicals, are also abnormal in schizophrenia.

In particular, there is a neurotransmitter called dopamine

that is often thought to be too high or elevated

in certain parts of the brain in schizophrenia,

and quite a number of the medicines I use

to treat schizophrenia, the anti-psychotic medicines,

Unfortunately, brain scans, measuring neurotransmitters,

none of these tests ever diagnose schizophrenia.

Because we know that these brain changes may actually

and changes in the way they act, and we think about ways

that people with schizophrenia may think differently.

We start to think about having abnormal beliefs,

something that we actually call delusions,

and they may also happen to see and hear things that

aren't there, something that we refer to as hallucinations.

Now, people can have delusions and hallucinations

Also, the way that they act may be different.

especially to people looking at them from a distance.

They may have something that we call a flat affect,

and that basically means they lack emotions on their face.

but we can start to see that the way that they think

and the way that people with schizophrenia act,

there's a lot of changes here that people would

start to feel maybe abnormal or different.

Now, let's think a little more widely about schizophrenia.

Well, we know that approximately one percent

The exact number is actually a little bit less than that

and we know that males are typically affected

that this is a condition that affects people

and in older individuals, this is the most common age group,

with males being affected at a younger age than females.

that there is something called the prodrome

and the prodrome represents a period of time

before schizophrenia, the symptoms are fully present,

but it's actually a kind of deterioration

and in the prodrome, typically what may happen is

but what you will notice is their academic or schoolwork

may suffer, and I say schoolwork because if you think about

between 16 and 30, and if the prodrome precedes that,

that are often still in the educational system,

but if they're working, the work can suffer.

so they may develop some of these delusional ideas

The prodrome then often leads to schizophrenia

and we know that if somebody has schizophrenia,

they are at risk of having lots of different consequences.
