# Overview
Separation anxiety disorder is a psychological condition in which an individual has excessive anxiety regarding separation from home or from people to whom the individual has a strong emotional attachment (like a mother).  Often, separation anxiety disorder is a symptom of a co-morbid condition. Studies show that children suffering from separation anxiety disorder are much more likely to have ADHD, bipolar disorder, panic disorder, and others later in life.   Separation anxiety disorder should not be confused with separation anxiety, which occurs as "a normal stage of development for healthy, secure babies."

Separation anxiety disorder should not be confused with separation anxiety, which occurs as "a normal stage of development for healthy, secure babies."  Separation anxiety occurs as babies begin to understand their own selfhood - or understand that they are a separate person from their primary caregiver. At the same time, the concept of object permanence emerges - which is when children learn that something still exists when it is not seen or heard. As babies begin to understand that they can be separated from their primary caregiver, they do not understand that their caregiver will return, nor do they have a concept of time. This, in turn, causes a normal and healthy anxious reaction.
