RAD is a disorder that a child might suffer from a young age. According to this disorder, a child might not show feelings of emotional attachment to their parents or close ones. If not treated, the child will grow to have RAD throughout their lives.

If a person is deprived of basic emotions of affection, care and love in their childhood, they might grow to have difficulty in expressing their feelings or emotionally attaching themselves to anyone. They might give a hard time to people who love them but the disorder is treatable by following different therapies or treatments.
