Topic 1: Neurobiology & Foundation of Addiction (Questions 1-10)
1. A 45-year-old male with severe alcohol use disorder reports intense cravings
whenever he drives past a specific liquor store. This phenomenon is best
explained by which neurobiological mechanism?
a) Downregulation of GABA-A receptors in the prefrontal cortex.
b) Conditioned cue-induced dopamine release in the nucleus accumbens.
c) Upregulation of serotonin transporters in the raphe nuclei.
d) Antagonism of NMDA receptors in the hippocampus.
Rationale: Cues associated with drug use (conditioned stimuli) trigger dopamine
release in the nucleus accumbens (the reward center), driving craving and relapse
risk, even after long periods of abstinence .
2. A patient on buprenorphine/naloxone (Suboxone) misses two doses and
reports feeling mild withdrawal symptoms, including yawning and muscle
aches. What pharmacological property explains this?
a) Naloxone is a long-acting antagonist that accumulates in the system.
b) Buprenorphine is a partial agonist with high receptor affinity but low intrinsic
activity.
,c) Buprenorphine is a full agonist that causes rapid tolerance.
d) The patient is experiencing a "histamine reaction" to the medication filler.
Rationale: Buprenorphine is a partial mu-opioid agonist. It occupies receptors
(preventing full agonists from working) but does not activate them completely. When
levels drop, the partial activation is insufficient to mask underlying withdrawal .
3. Chronic methamphetamine use leads to psychosis characterized by paranoia
and formication (sensation of bugs on skin). This is most directly associated
with:
a) Glutamate deficiency in the thalamus.
b) Dopamine dysregulation in the mesolimbic and mesocortical pathways.
c) Acetylcholine excess in the neuromuscular junction.
d) Norepinephrine depletion in the locus coeruleus.
Rationale: Methamphetamine causes massive release and blocks reuptake of
dopamine. Chronic use leads to dopamine dysregulation in the mesolimbic pathway
(causing positive psychotic symptoms) .
4. A patient with alcohol use disorder has a seizure 24 hours after his last drink.
This seizure is primarily due to:
a) Acute GABA-A receptor overactivity.
b) Upregulation of NMDA receptors leading to glutamate-mediated hyperexcitability.
c) Sudden drop in blood alcohol concentration causing vasodilation.
d) Depletion of serotonin in the brainstem.
Rationale: Chronic alcohol inhibits NMDA receptors (glutamate). The brain
compensates by upregulating NMDA receptors. Upon alcohol withdrawal, these
receptors are overactive without inhibition, leading to glutamate excitotoxicity and
seizures .
5. A 28-year-old patient is admitted in a confused state. Family reports he
recently stopped drinking. He is ataxic and has bilateral ophthalmoplegia (sixth
nerve palsy). Which brain structure is likely affected, and what is the treatment?
a) Substantia nigra; Levodopa.
, b) Nucleus accumbens; Naloxone.
c) Mammillary bodies and thalamus; IV Thiamine.
d) Hippocampus; Lorazepam.
Rationale: This describes Wernicke's Encephalopathy (ataxia, ophthalmoplegia,
confusion) caused by thiamine (B1) deficiency, common in alcohol use disorder. The
brain areas most affected are the thalamus and mammillary bodies .
6. The "telescoping" effect refers to:
a) The rapid development of tolerance to the sedative effects of alcohol.
b) A pattern in certain addictive disorders where women progress from initiation to
dependence faster than men.
c) The phenomenon where one substance masks the effects of another.
d) A memory distortion common in Korsakoff's syndrome.
Rationale: Telescoping is a well-documented gender difference in addiction where
females often start using substances later than males but progress more rapidly to
dependence and treatment entry .
7. The insula has been identified as a critical region in addiction neurobiology.
Damage to this area has been shown to:
a) Eliminate the rewarding effects of cocaine.
b) Disrupt the conscious urge to smoke in patients with nicotine dependence.
c) Prevent the development of tolerance to opioids.
d) Enhance the sedative effects of alcohol.
Rationale: The insula processes interoceptive awareness (bodily feelings). Studies
show that smokers with damage to the insula are more likely to quit easily because
they lose the bodily sensation of craving .
8. A patient asks why nicotine is so addictive. The APRN explains that nicotine:
a) Acts as a monoamine oxidase inhibitor (MAOI), increasing dopamine availability.
b) Is a direct full agonist at the mu-opioid receptor.
c) Binds to nicotinic acetylcholine receptors, causing dopamine release in the nucleus
