What brain area is associated with working memory in ADHD?
......ANSWER......Prefrontal Cortex
Which brain area is linked to temporal processing in ADHD?
......ANSWER......Cerebellum
What is the role of the nucleus accumbens in ADHD? ......ANSWER......It
is associated with delay of gratification.
What compensatory change occurs in the parietal cortex of children
who outgrew ADHD? ......ANSWER......Normalization of gray matter
thickness.
How do ADHD symptoms change from childhood to adulthood?

What is the effect of stimulant medication on dopamine in ADHD?
......ANSWER......It increases dopamine release at the nucleus
accumbens, improving impulse control.
What happens to the total brain volume in children with ADHD?
......ANSWER......It is approximately 5% smaller across all cerebral
lobes.
What is the primary pathological finding in Alzheimer's dementia?
......ANSWER......Cortical atrophy and neuronal loss.
What are amyloid plaques and their significance in Alzheimer's?
......ANSWER......They are extracellular deposits of beta-amyloid
protein that contribute to neuronal damage.
What causes neurofibrillary tangles in Alzheimer's disease?
......ANSWER......Hyperphosphorylation of tau proteins leads to their
detachment from microtubules, forming tangles.
What is the hallmark sign of Alzheimer's disease?
......ANSWER......Shrinkage of cortical tissue due to neuronal cell death.
How does drug abuse affect the nucleus accumbens?
......ANSWER......Chronic cocaine use downregulates dopamine
receptors in the nucleus accumbens.
