In this episode, I dive into the evolving understanding of Cognitive Disengagement Syndrome (CDS), formerly known as sluggish cognitive tempo. I explain why we are moving away from the older terminology toward a label that more accurately describes the internal mechanisms of the brain. We explore the neurobiological differences between CDS and traditional ADHD, specifically looking at the posterior attention system and the default mode network. I share how these differences manifest in clinical testing, such as the slow and accurate profile on processing speed tasks, and offer concrete tips for adjusting your assessment battery. We also touch on why traditional stimulant medications might not be the first line of defense for these individuals and what environmental primers might work better to wake up their attention systems.
