There appeared to be some evidence that 10 Hz stimulation (alpha waves) improved anxiety, but it wasn’t statistically significant. A study that utilized a ramping format of alpha to theta to delta waves (over the course of 10 minutes) found a significant improvement in anxiety. In terms of long-term stress, there is evidence that alpha and beta stimulation improved measures of “competence” and “emotional exhaustion.”
In a recent national survey, 44 percent of adults said stress had caused sleepless nights at least once in the previous month. All that tossing, turning and staring at the ceiling can leave you feeling tired and more stressed the next day.

However, those with ASD are sometimes also diagnosed with ADHD. Although they are different conditions, some of the symptoms can be intertwined, which it appears may be the case with your grandson. So I would start by trying out my tracks for ADHD. You can try those out for free on my YouTube channel and I’ve put them together in a playlist here: https://www.youtube.com/watch?v=RKao2oZZPnw&list=PLveg0IEcZWN5iVmMduR9UjLzX_YgCetds. The corresponding MP3 versions for those tracks can be found on my site here: https://www.mindamend.com/intelligence-and-brain-power/. I hope that helps.
Anyone who has sought out different methods for enhancing cognitive ability will probably have come across a technique known as Brainwave Entrainment. However, it is a fairly niche area of brain training, meaning that this form of stimulation is often overlooked in favour of more mainstream methods. The following outlines what Brainwave Entrainment actually is, how it is used, and some of the benefits attributed to it.
This unique session works the opposite to most sessions. It attempts to to ‘dis-entrain’ the brain, breaking stuck thinking patterns and allowing a fresh way of thinking. The recording contains random and chaotic isochronic tones spanning 7.83 to 18 Hz, played over a background of gamma-embedded noise. Use this session to sit back and allow fresh ideas and new connections to form. Finishes at the illuminating14Hz sensorimotor rhythm frequency.
