So is Neural Agility basically Auditory Beat Stimulation (monaural- and binaural-beat frequencies)? I downloaded the brain.fm thing to try that. As far as ABS I found studies stating, "While findings for most putative applications up to now are either solitary or contradictory, several studies consistently report a diminishing impact of binaural-beat stimulation on anxiety levels." So that is promising but I don't imagine it could actually be "meditation on steroids" as Dr. Bredesen says in his book. Meditation has really good studies on its effectiveness.
I agree with your assessment of Neural Agility. I've also taken a dive into the science and found it to be pretty
weak. I think Dr. Bredesen likes it, because (unlike meditation) it's a passive process. Listeners simply slip on their headphones and relax while the magic "happens." This likely has been helpful for his patients
with cognitive decline who are unable to otherwise actively meditate. The 30 min. rest period is probably calming.
FWIW, I've also taken a deep dive into the science behind meditation and found it be be exceptionally
strong. I've fairly recently completed the online version of
Ziva, which is a slightly more accessible version of Transcendental Meditation, and found it be the best meditation instruction I've encountered to date. Unfortunately, it's pricey at $399. There's also a free website & app called
Insight Timer which offers a library of guided meditations, some instructional, that is full of great material. If your cognition is intact enough to actively engage in meditation, I strongly recommend that vs. Neural Agility. A daily meditation practice has been very beneficial for me, personally, and there's overwhelming scientific evidence to support this strategy as a means to reduce stress, promote overall wellness, and avoid cognitive decline.
