Children can also experience reactive attachment disorder (RAD). RAD is defined as markedly disturbed and developmentally inappropriate social relatedness, that usually begins before the age of 5 years. RAD can present as a persistent failure to start or respond in a developmentally appropriate fashion to most social situations. The long-term impact of emotional abuse has not been studied widely, but recent studies have begun to document its long-term consequences. Emotional abuse has been linked to increased depression, anxiety, and difficulties in interpersonal relationships (Spertus, Wong, Halligan, & Seremetis, 2003). Victims of child abuse and neglect are more likely to commit crimes as juveniles and adults.
