Genetic and environmental risk factors appear to act via a common pathway
of disrupting the function of 1 or more neurotransmitter components.
Dopaminergic theory: Almost all drugs with antipsychotic properties block the dopaminergic D2
receptor.
However, antipsychotics are only 70% effective and clozapine, the most effective antipsychotic for
treating schizophrenia, is a weak D2 antagonist.
Hyperactivity of dopamine D2 receptor neurotransmission in subcortical, and limbic brain regions
contribute to the positive symptoms of schizophrenia. Hypo functionality of dopamine D1 receptor
neurotransmission in the prefrontal cortex contributes to both negative and cognitive symptoms. -
