Reactive attachment disorder is a disturbance of social interaction caused by neglect of a child's basic physical and emotional needs, particularly during infancy.
Babies placed in orphanages at birth and raised by multiple caretakers without primary parent-figures can also develop this disorder, even if physical care was adequate.
Reactive attachment disorder is caused by neglect of an infant's needs for physical safety, food, touching, and emotional bonds with a primary and/or secondary caretaker.
The risk of neglect to the infant or child is increased with parental isolation, lack of parenting skills, teen parents, or a caregiver who is mentally retarded. A frequent change in caregivers (for example, orphanages or foster care) is another cause of reactive attachment disorder.
Children adopted from foreign orphanages are commonly affected, particularly if they were removed from their birth parents during the first weeks of life.
