The dopamine hypothesis suggests that schizophrenia is caused by an overactivity of dopamine neurons.
A leading neurobiological hypothesis looks at the connection between the disease and excessive levels of dopamine, a chemical that transmits signals in the brain (neurotransmitter).
Dopamine. Increase in dopemine is a possible cause for schizophrenia.
Typically, the temporal lobe and limbic system are involved in schizophrenia. Lesions, malformations, or simply dysfunction in dopaminergic neurons of these areas of the brain can result in the positive and negative symptoms of schizophrenia. Since excess dopaminergic activity is indicative of schizophrenia, antipsychotic drugs that block dopamine receptors are the usual treatment for this illness.
A lack of dopamine causes Parkinson's disease. As dopamine is an interneuron synaptic neurotransmitter, it controls the passage of impulses along different neurons. If it can't regulate the signal, this leads to frequent involuntary movements as in Parkinson's.

Dopamine is produced in the substantia nigra of the brain as well as in the ventral tegmental area (VTA) of the midbrain and the arcuate nucleus of the hypothalamus.
Schizophrenia is often associated with a high level of the neurotransmitter dopamine.
Dopamine is most involved in schizophrenia.
Schizophrenia is related to increased levels of dopamine.

Schizophrenia
An over-abundance of dopamine is thought to contribute to the development of schizophrenia.
Dopamine. which is a neurotrasmitter in the brain.
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.
Drugs act on the neurons in the reward pathway of the brain. Drugs increase the release of dopamine.
Dopamine or serotonin antagonist e.g. risperidone or amisulpride.
