Reactive Attachment Disorder (RAD) is a condition where children fail to form normal attachments to caregivers. There are two subtypes - inhibited and disinhibited. It results from pathogenic or severely neglectful care before age 5. Diagnosis involves disturbed social relationships and lack of appropriate response to caregivers. Treatment aims to enhance security, stability and caregiver sensitivity through parenting skills training, play therapy, and establishing consistent routines and discipline. The goal is to help the child form a secure attachment to promote healthy development.
