1. What brain area is associated with working memory in ADHD? - Correct
Answer: Prefrontal Cortex
2. Which brain area is linked to temporal processing in ADHD? - Correct
Answer: Cerebellum
3. What is the role of the nucleus accumbens in ADHD? - Correct Answer:
It is associated with delay of gratification.
4. What compensatory change occurs in the parietal cortex of children who
outgrew ADHD? - Correct Answer: Normalization of gray matter
thickness.
5. How do ADHD symptoms change from childhood to adulthood? -
Correct Answer: Symptoms may diminish or change in presentation as
individuals mature.
6. What impact does trauma have on the prefrontal cortex? - Correct
Answer: It impairs working memory.
, 7. What is the effect of stimulant medication on dopamine in ADHD? -
Correct Answer: It increases dopamine release at the nucleus accumbens,
improving impulse control.
8. What happens to the total brain volume in children with ADHD? -
Correct Answer: It is approximately 5% smaller across all cerebral lobes.
9. What is the primary pathological finding in Alzheimer's dementia? -
Correct Answer: Cortical atrophy and neuronal loss.
10.What are amyloid plaques and their significance in Alzheimer's? -
Correct Answer: They are extracellular deposits of beta-amyloid protein
that contribute to neuronal damage.
11.What causes neurofibrillary tangles in Alzheimer's disease? - Correct
Answer: Hyperphosphorylation of tau proteins leads to their detachment
from microtubules, forming tangles.
12.What is the hallmark sign of Alzheimer's disease? - Correct Answer:
Shrinkage of cortical tissue due to neuronal cell death.
13.How does drug abuse affect the nucleus accumbens? - Correct Answer:
Chronic cocaine use downregulates dopamine receptors in the nucleus
accumbens.
