16

Increase in prolactin secretion when DA is low
17
What are the BRAIN goals of schizophrenia treatment?

INCREASE mesocortical pathway (negative symptoms);
HAVE NO EFFECT ON tuberoinfundibular pathway and nigrostriatal pathway
18

D2
26
Haloperidol and Chlorpromazine are what kinds of drugs?
Traditional, typical first generation antipsychotics
--more side effects in nigrostriatal and tuberoinfundibular pathways
27
Use: Clozapine
Atypical antipsychotic;
first line for schizophrenia;
5HT2a blockade allows dopamine to move more freely in the nigrostriatal path
28
Use: Risperidone
Atypical antipsychotic;
first line for schizophrenia;
5HT2a blockade allows dopamine to move more freely in the nigrostriatal path --> less neurological side effects
29
Use: Paliperidone
Atypical antipsychotic;
first line for schizophrenia;
5HT2a blockade allows dopamine to move more freely in the nigrostriatal path --> less neurological side effects
