"If one reviews the symptoms above, several points of intersection with ADD can be seen. The poorly defined inner self of the borderline can closeley resem,ble the distracted, fragmented self of the person with ADD. The abrupt breaking off of relationships is not uncommon in ADD when the individual inadvertently simply tunes out. The person with ADD seeks high stimulation in order to focus, while the borderline person seeks high stimulation to deal with painful feelings. Both syndromes are marked by a high degree of impulsibity. The person with ADD carries a great deal of anger, due to frequent frustration over not getting things right, while the perosn with a borderline syndrome carries much anger due to frequent frustration over not getting his or her emotional needs met. In both syndromes substance abuse is not uncommon as a form of self-medication." (Hallowell and Ratey 2011)
