Question: Answer:
What are the three major hypotheses of psychosis and their Dopamine theory - hyperactive dopamine at D2 receptors in the
neurotransmitter networks? mesolimbic pathway
Glutamate theory - NMDA receptor hypofunction
Serotonin theory - 5HT2A receptor hyperfunction in the cortex
Question: Answer:
Briefly explain the dopamine hypothesis of the positive and The dopamine hypothesis of schizophrenia consists of:
negative symptoms of schizophrenia. There is too much dopamine activity in the mesolimbic dopamine
pathway, which leads to
positive symptoms (such as hallucinations and delusions).
There is also too little dopamine activity in the mesocortical
dopamine pathway, which
leads to negative symptoms (such as blunting of affect, poverty of
speech, anhedonia,
and so on).
