We break down how ADHD affects the brain's circuits, especially in areas like planning, emotional regulation, and time management. Then we discuss practical strategies to scaffold and support these executive functions, making them more manageable for those with ADHD.

If you've ever struggled with procrastination, organisation, or emotional overwhelm, this episode offers both insights and actionable tips to help you thrive.

Key Discussion Points:

Executive functions as project managers and air traffic controllers (00:01:12)
Katherine explains executive functions in relatable terms, highlighting their role in coordinating the brain’s activities.
The science behind executive function challenges (00:03:10)
Dr. Russell Barkley's definition of executive functions is discussed, along with ADHD's impact on these brain circuits. Barkley describes them as the "who, what, when, how, and why" circuits of the brain. Reference: Dr. Russell Barkley’s Research.
Working memory difficulties (00:05:07)
Katherine shares personal insights about how ADHD affects working memory, which can only hold around 7 pieces of information. She discusses why people with ADHD often struggle to manage these limits.
The role of the prefrontal cortex in ADHD (00:06:20)
ADHD impacts the prefrontal cortex, affecting gray matter volume, which in turn influences planning and emotional regulation.

Breaking tasks into smaller steps (00:10:29)
Practical tip for reducing overwhelm by breaking large tasks into manageable pieces. Katherine recommends using sticky notes to create small, bite-sized steps to overcome emotional overwhelm and procrastination.
Mindfulness and emotional regulation (00:15:10)
Katherine discusses the benefits of mindfulness and grounding techniques for emotional regulation, referencing a 2016 meta-analysis by Veehof.

‍‍ Accountability and demand avoidance (00:15:55)
Katherine reflects on the challenges of accountability for ADHD individuals and the importance of maintaining autonomy. She emphasizes the need for equal partnerships in accountability systems rather than a top-down structure.
