The 'interest-based nervous system' model by Dr. William Dodson states ADHD brains are activated by tasks that are:
Answer: Novel, urgent, challenging, or personally interesting
Dodson's model explains that ADHD brains require novelty, urgency, challenge, or passion for activation rather than responding to importance alone.
Norepinephrine's role in ADHD primarily affects which function?
Answer: Alertness and attention regulation
Norepinephrine works alongside dopamine to regulate alertness and attentional control in the prefrontal cortex.
The default mode network (DMN) in ADHD brains is problematic because it:
Answer: Remains active during task performance instead of suppressing
Research shows the DMN fails to suppress adequately during tasks in ADHD brains, competing with task-focused networks and causing mind-wandering.
Emotional dysregulation in ADHD is neurologically linked to impaired connectivity between which two regions?
Answer: Prefrontal cortex and amygdala
Impaired top-down regulation from the prefrontal cortex over the amygdala results in the intense emotional reactions characteristic of ADHD.
The 'wall of awful' concept describes how ADHD clients experience task initiation as:
Answer: An emotional barrier built from accumulated past failures and shame
The 'wall of awful' describes the accumulated emotional weight of past ADHD-related failures that creates an invisible barrier to starting tasks.
Reward pathways in ADHD are characterized by:
Answer: Delayed reward insensitivity and reduced dopamine response
ADHD brains show reduced dopaminergic response to rewards, especially delayed rewards, making long-term motivation neurologically challenging.
