Attachment disorders stem from infants who experience some kind of disruption in the bond with their primary caretaker and as a result are unable to form a secure, loving, attached relationship. Such children typically become anxious, depressed or apathetic and fail to follow normal patterns of physical, emotional, social and intellectual development. As adults, people with attachment disorders have great difficulty in interpersonal relationships. Some need almost constant contact and reassurance, others primarily need to be left alone and can’t tolerate much intimacy and still others go back and forth between the two extremes.
