Understanding Attentional Blink and its Link to ADHD

Episode notes

In this episode, I discuss ADHD (Attention-Deficit Hyperactivity Disorder): what it is, the common myths, and the biology and psychology of ADHD.

I discuss both behavioral and pharmacologic treatments for ADHD, and brain-machine interface tools. I also discuss behavioral training protocols that can improve focus in people with ADHD and those without ADHD, and for people of different ages. I discuss the role of dopamine in coordinating 'default-mode' and 'task-related' neural networks, attentional "blinks" (lapses of attention) and how to overcome them, and the role of actual blinks in time perception and attention. Finally, I review some of the prescription and over-the-counter compounds for increasing focus such as Adderall, Ritalin, Modafinil and Armodafinil, the racetams, Alpha-GPC and phosphatidylserine and the role of diet for managing ADHD (and the controversies of diet for ADHD).

The role of cell phones/technology in ADHD and ADHD-like challenges with focus are also discussed. Throughout, both basic science and clinical scenarios, as well as applicable tools and resources are covered.
