Schizophrenia

What are the symptoms of schizophrenia?
Schizophrenia means you have problems with the way your brain works. This affects the way you see the world, and the way you
think and feel.
There are three main types of symptoms that people get with schizophrenia. How often you get these symptoms varies a lot from
person to person. The three types are:
- Losing touch with reality (a psychotic episode)
- Feeling withdrawn, isolated or emotionless (called negative symptoms)
- Having problems with your thinking and memory.

- Beliefs that couldn't be true. These are called delusions. Delusions are beliefs that you hold very firmly, even when they don't stand up to reason. For example, you might believe someone is trying to poison you, or control your thoughts. Or you might believe you are very powerful and can control other people
- Experiences no-one else shares. These are called hallucinations. You might hear voices inside your head, when there's nobody there. But hallucinations aren't just sounds. You might smell, see or feel things that are not really there.

People often think schizophrenia only means people hear voices or have delusions. But, some of the most upsetting symptoms
can be when people don't feel or show any emotion. Doctors call these negative symptoms, because you're missing some of the emotions and behaviors that you used to have.
Here are some of the negative symptoms you can get with schizophrenia:

- Appearing to be in a very flat mood when you don't care about anything
- Not enjoying things that you used to enjoy
- Not showing any expression on your face
- Being unable to pay attention to anyone or anything.
Unfortunately, antipsychotics don't work as well for negative symptoms as they do for hallucinations and delusions.

Negative symptoms are not just caused by schizophrenia itself. They may be caused by other things that happen as a result
of schizophrenia. They might happen because:

- You're depressed
- You're frightened by hallucinations
- You're bored, for example, if you have to stay in the hospital and there isn't much to do.
If you have schizophrenia, you may find it hard to think in an organized way. This can make it hard to concentrate, to speak
to people or to solve problems. Here are some of the problems you can have if you have difficulties with your thinking and
memory:
- Finding it hard to concentrate when you are reading or writing
- Finding it hard to learn new skills
- Having jumbled up speech that is hard for other people to follow. You might jump from one topic to another, making it hard for other people to follow what you're trying to say
- Being very disorganized. This can make it hard for you to care for yourself. For example, you might not be able to cook a meal properly. You might dress in an odd or very scruffy way. Or you might not be able to wash and take care of how you look.
The symptoms of schizophrenia can make life very difficult. You may find everyday tasks take much more effort than they did
before. If you have schizophrenia, it's common to feel very anxious or to have angry outbursts. You may also find that you
are thinking about death a lot, or even about committing suicide.

- Become quiet when you're with people or spend most of the time alone
- Lose interest in work or studying

- Care less about how you look, so you don't wash or dress properly.
