Is it true that schizophrenics have an excess of dopamine?
That is one of the theories. The other theory is tied to the function of dopamine. Dopamine inhibits another chemical called GABA. Without any GABA dopamine doesn't really do anything. The other theory is that they have normal levels of Dopamine and low levels of GABA. These theories came about by the observation that anti-dopamine drugs help the symptoms. The simple answer is we're not quite sure yet.
What primary neurotransmitters are involved in schizophrenia?
Dopamine. Increase in dopemine is a possible cause for schizophrenia.
Which neurotransmitteres play role in psychosis?
As far as we know, dopamine is the main culprit in psychosis. Autospies have shown excess dopaminergic receptors in the brain's of people who suffered psychosis. Other neurotransmitters are also affected.
Too much of this neurotransmitter can cause schizophrenia?
An over-abundance of dopamine is thought to contribute to the development of schizophrenia.
The neurotransmitter most likely produced when a person uses a drug that creates a sense of well-being is?

What neurotransmitter is associated with schizophrenia?
Schizophrenia is often associated with a high level of the neurotransmitter dopamine.
Schizophrenia is thought to occur when a person has overactivity within this particular neurotransmitter system?
Dopamine is most involved in schizophrenia.
What are three brain abnormalities in schizophrenia?
They are postulated to be 1) excess secretion of dopamine, 2) deficiency of serotonin, and 3) deficiency of norepinephrine (among others).
Schizophrenia is related to increased levels of what?
Schizophrenia is related to increased levels of dopamine.
Which schizophrenia is caused by dopamine neurons?
The dopamine hypothesis suggests that schizophrenia is caused by an overactivity of dopamine neurons.

What is schizophrenia and how does it relate to the biological approach?
Schizophrenia is a psychotic disorder or group of disorders that affects the normal functioning of the brain and severely impairs thinking, emotion, and behavior. Doctors do not know the specific cause of schizophrenia, but both environmental and genetic factors do play a role. The symptoms of schizophrenia are delusions, hallucinations, flat affect, and disorganized speech, thinking, and behavior. Schizophrenia relates to the biological approach to psychological disorders in that it is a primarily biological disorder. Schizophrenia is sometimes caused by an excess of the neurotransmitter dopamine, and there are brain defects associated with schizophrenia. Because of this, schizophrenia can be said to be a biological psychological illness.
