Reactive attachment disorder (RAD) is a condition where individuals have difficulty forming loving relationships and trusting others due to inadequate care during early childhood. Children with RAD lack an internalized sense of security and display self-centered, impulsive, and immature behaviors. RAD is caused by a lack of attachment before age 3 due to factors like abuse, neglect, unstable caregiving situations, or unprepared parenting. Symptoms include a lack of affection with caregivers, destructive behavior, poor impulse control, and abnormal social skills. Treatment focuses on therapeutic parenting that can help children with RAD learn to love and function healthily.
