CAA CAA ADHD Neuroscience and Brain-Based Understanding 2

Question 1

The 'interest-based nervous system' model by Dr. William Dodson states ADHD brains are activated by tasks that are:

Accepted Answer

Novel, urgent, challenging, or personally interesting

Answer

Dodson's model explains that ADHD brains require novelty, urgency, challenge, or passion for activation rather than responding to importance alone.

Question 2

Norepinephrine's role in ADHD primarily affects which function?

Accepted Answer

Alertness and attention regulation

Answer

Norepinephrine works alongside dopamine to regulate alertness and attentional control in the prefrontal cortex.

Question 3

The default mode network (DMN) in ADHD brains is problematic because it:

Accepted Answer

Remains active during task performance instead of suppressing

Answer

Research shows the DMN fails to suppress adequately during tasks in ADHD brains, competing with task-focused networks and causing mind-wandering.

Question 4

Emotional dysregulation in ADHD is neurologically linked to impaired connectivity between which two regions?

Accepted Answer

Prefrontal cortex and amygdala

Answer

Impaired top-down regulation from the prefrontal cortex over the amygdala results in the intense emotional reactions characteristic of ADHD.

Question 5

The 'wall of awful' concept describes how ADHD clients experience task initiation as:

Accepted Answer

An emotional barrier built from accumulated past failures and shame

Answer

The 'wall of awful' describes the accumulated emotional weight of past ADHD-related failures that creates an invisible barrier to starting tasks.
