23
Q

Lesions related to delusions are typically

A

Right frontal

24
Q

A popular candidate for area specific to delusions

A

Right dorsolateral prefrontal cortex

25
Has been shown to be attenuated by dopamine receptor blockers
Jumping to conclusions
26
Has been associated with pre-frontal functioning, especially the right dorsolateral prefrontal cortex
Psychosis
27
Equal prevalence across genders, but tends to present earlier in men compared to women
Schizophrenia
28
Symptoms last greater than 6 months
Schizophrenia
29
Only delusions, must have for more than one month
Delusional disorder
30
Symptoms lasting only 1-6 months
Schizophreniform
31

Mood disorder (I.e. major depression or bipolar)
34
A common CT finding in schizophrenia is

Schizophrenia
41
Mainly treats hallucinations and delusions -Less consistent for symptoms of disorganization of negative symptoms
Dopamine Receptor Blocking Agents (DRBAs)
42
First generation “high potency” DRBAs were predominantly
Dopamine receptor antagonists
43
First generation “low potency” DRBAs were dopamine antagonists, but also strongly
Anticholinergic
44
Dopamine receptor antagonists with serotonin activity
Second generation DRBA’s
45
