I am reading all of the post about ADD and executive functions. Having never heard the term “executive functions” I had to google. I discovered that my son is executive functionally impaired!! I had no idea. I knew about the ADD, but didn’t realize the other part had a name. For those who have found success with CBD oils in improving the symptoms of ADD and executive functioning, what kind of oil did you use? There are so many different types of oils for different ailments. Can someone tell me what kind of oils you used (not the brand)?
