Often the severe emotional damage to abused children does not surface until adolescence or later, when many abused children become abusing parents. An adult who was abused as a child often has trouble establishing intimate personal relationships. These men and women may have trouble with physical closeness, touching, intimacy, and trust as adults. They are also at higher risk for anxiety, depression, substance abuse, medical illness, and problems at school or work. Without proper treatment, physically abused children can be damaged for life.
