Attachment isorder is a broad term intended to describe disorders of mood, behavior, and social relationships arising from a failure to form normal attachments to primary care giving figures in early childhood, resulting in problematic social expectations and behaviors. Such a failure would result from unusual early experiences of neglect, abuse, abrupt separation from caregivers after about six months but before about three years, frequent change of caregivers or excessive numbers of caregivers, or lack of caregiver responsiveness to child communicative efforts. A problematic history of social relationships occurring after about age three may be distressing to a child, but does not result in attachment disorder.
