The DSM-V recognizes two distinct attachment disorders: Disinhibited social engagement disorder A classic sign of disinhibited social engagement disorder is overfriendliness with strangers. A child may seek comfort from a stranger, sit on a stranger’s lap, and not exhibit any distress when a caregiver isn’t present. Reactive attachment disorder Reactive attachment disorder is a disorder of infancy or early childhood that involves a failure to seek comfort from a caregiver. A child with reactive attachment may resist physical comfort from a caregiver, avoid eye contact, and be hypervigilant. Most children with reactive attachment disorder display a variety of problematic behaviours.
