Which neurotransmitter is primarily implicated in ADHD's impact on attention regulation?
Answer: Dopamine
Dopamine dysregulation in the prefrontal cortex is the primary neurochemical factor underlying attention difficulties in ADHD.
Which brain region's dysfunction most directly accounts for working memory deficits in ADHD?
Answer: Prefrontal cortex
The prefrontal cortex governs working memory, and its reduced volume and activity in ADHD directly causes working memory impairments.
According to Russell Barkley's model, ADHD is fundamentally a disorder of:
Answer: Behavioral inhibition and self-regulation
Barkley frames ADHD as a failure of behavioral inhibition that cascades into deficits in self-regulation and executive function.
The neurological explanation for 'hyperfocus' in ADHD is best described as:
Answer: Dopamine surge during high-interest tasks
Hyperfocus occurs when highly stimulating activities trigger sufficient dopamine release to sustain attention without impairment.
Executive function development in individuals with ADHD typically lags neurotypical peers by approximately:
Answer: 3–5 years
Research by Barkley indicates executive function development in ADHD is delayed by approximately 3–5 years compared to neurotypical peers.
Which concept explains why ADHD clients can perform well one day but struggle significantly the next?
Answer: Inconsistent dopamine availability
Day-to-day variability in ADHD performance reflects inconsistent neurochemical availability rather than willpower or effort.
