I have a son who used to have ADHD, so whenever I heard a rabbi speaking about this topic, I tuned in. However, to date, not one of these rabbis has ever had anything sensible to say about it, and to my horror some have even made fun of the problem, or denied that it even exists ! Finally Rabbi Alon Anava has once again come to the rescue. He explains the spiritual reason, according to Kabbalah, although as he points out, if you want to really understand the process you would need to spend three years in a Yeshiva - but he does give us some great insights. This is really something to think about, and if you are one of those people who ridicules the very real problem that exists, think again.
