ADHD wasn't diagnosed very much until the mid 1900s. Charlotte Mason was at the end of her life around that time, so it is very likely she never heard of ADHD. But we all know that the habit of attention is dwindling in many children as well as adults because of our current way of life. Because of this, we can all benefit from some wonderful techniques that Miss Mason used in her school. She said "children have naturally great power of attention." And following her methods yields great results in people with or without ADHD.
