This lesson is going to cover a schizophrenia by looking at:
The most recognized type of psychotic disorder is schizophrenia. Schizophrenia is a psychotic disorder that's characterized specifically by disorganized or inconsistent thoughts, emotions, and behavior. This is why it's sometimes referred to as a thought disorder as opposed to a mood disorder.
Schizophrenia often develops during the teen years when a person has their first psychotic break from reality. It's related to both heredity and environmental factors. While there is a genetic aspect, it's related to certain environmental factors like family life.
This disorder is related to the neurotransmitter of dopamine. This is why a lot of antipsychotic drugs are used to treat this disorder. They work to block dopamine uptake within the brain.
There are certain major symptoms that are characteristic of schizophrenia in general. The actual symptoms that are displayed by the person can depend on the type of schizophrenia that they have. The general symptoms are:
Many people have speculated that this disorganized speech and thought has a lot to do with problems in selective attention within people with schizophrenia. People with this disorder can't focus on one thing at a time. It's like all the floodgates are open, and so all thoughts and as a consequence all speech is constantly coming out of that person.
Negative symptoms are things that you expect to see within a person but don't actually. These are normally occurring things that a person with schizophrenia doesn't have. Those with schizophrenia can have a lack of emotions or a lack of appropriate emotions to be specific.
A person might not display emotions or they might display the wrong ones for the situation. If they receive bad news, they might start laughing hysterically.
Other negative symptoms within schizophrenia include speaking less, moving less, and even becoming catatonic.
Researchers and commissions had noticed that there are certain groups of seemingly different symptoms that occur under the blanket disorder of schizophrenia. Because a lot of these symptoms occur together, they've been grouped together into specific categories. There are four to look at for now:
