EXAM REVIEW (BRAND NEW!!)
1. Select the neurotransmitter that is most implicated in
schizophrenia based on the effectiveness of antipsychotic
drug therapy.
A. Norepinephrine
B. Dopamine
C. GABA
D. Glutamate
Answer: B
Rationale: The dopamine hypothesis of schizophrenia is supported
by the mechanism of action of antipsychotic drugs, which are
1
,primarily dopamine D2 receptor antagonists. All effective
antipsychotics block D2 receptors to some degree. While other
neurotransmitters (glutamate, GABA, serotonin) are involved,
dopamine remains central to the pathophysiology and treatment
response .
2. Bleuler identified "Four As" as fundamental symptoms of
schizophrenia. Select the symptom that is NOT among these
four.
A. Ambivalence
B. Affective disturbances
C. Arrogance
D. Autism
Answer: C
Rationale: Bleuler's "Four As" include Ambivalence (contradictory
thoughts/feelings), Affect disturbances (flat or inappropriate
2
,emotional expression), Autism (preoccupation with inner world,
withdrawal from reality), and loosening of Associations
(disorganized thinking). Arrogance is not one of Bleuler's
fundamental symptoms .
3. In the diagnosis of schizophrenia, symptoms must persist
for at least how long?
A. 1-2 months
B. 3-4 months
C. 6-8 months
D. 8-10 months
Answer: C
*Rationale: According to DSM-5-TR criteria, continuous signs of
the disturbance must persist for at least 6 months, including at
least 1 month of active-phase symptoms (delusions, hallucinations,
disorganized speech). This distinguishes schizophrenia from
3
, schizophreniform disorder (1-6 months) and brief psychotic
disorder (less than 1 month) .*
4. Which brain region shows the greatest anatomical
abnormalities in schizophrenic patients?
A. Hippocampus
B. Amygdala
C. Prefrontal cortex
D. Basal ganglia
Answer: C
Rationale: The prefrontal cortex demonstrates significant
anatomical abnormalities in schizophrenia, including reduced gray
matter volume and altered functional connectivity. While the
hippocampus and amygdala may show size decreases, prefrontal
cortex abnormalities are most consistently documented and
correlate with negative symptoms and cognitive deficits .
