A great essay from the weekend Wall Street Journal about maintaining brain health through aging, injury, and disease processes. There are no guarantees in life, but there is excellent proof that physical, emotional, intellectual, and social engagement in life enhances brain function into middle and old age. This article did not mention neurofeedback, but does discuss other forms of brain entrainment like auditory therapy. Neurotherapy is unique in that it persuades the brain’s own white and gray matter to perform training tasks on their own. It is a “learned” process that is dependent on the brain plasticity described in the article.
