Schizophrenia refers to a serious, complicated disorder of the mind that affects about one percent of the population. People who suffer from it usually have trouble with things like:

• Thinking clearly and logically.
• Behaving normally around other people.
• Telling the difference between the real world and the dream world.

Symptoms

The symptoms of schizophrenia usually develop slowly over several months, or even years. Sometimes, a person might experience a lot of the symptoms, while at other times, they might only experience a few of them.

People who suffer from any kind of schizophrenia might have trouble working, going to school and keeping friends. Other problems might include suicidal behaviors and thoughts, anxiety and depression.

At the beginning of their illness, a person with schizophrenia might experience:

• Trouble concentrating.
• Trouble sleeping.
• Feeling tense, anxious or irritable.

Medications

The most effective medications for schizophrenia to date are antipsychotic medications, which can change the brain's chemical balance and help control most symptoms of schizophrenia.
Although these medications are very useful, they can cause unwanted side effects. Most of the side effects can be treated or the patient may be switched to an alternative medication.

Possible side effects of antipsychotics include:

• Dizziness
• Restlessness and jitters
• Increased risk of high cholesterol or diabetes
• Drowsiness (sedation)
• Slower movements
• Tremors
• Weight gain
