Child sexual abuse victims report almost four times as many incidences of self-inflicted harm. Sexual assault among teenagers has been shown to lead to an increase in mental health problems, social exclusion and worse school performance. A well-documented, long-term negative effect is repeated or additional victimization in adolescence and adulthood. A causal relationship has been found between childhood sexual abuse and various adult psychopathologies, including crime and suicide, in addition to alcoholism and drug abuse. Males who were sexually abused as children more frequently appear in the criminal justice system than in a clinical mental health setting. A study comparing middle-aged women who were abused as children with non-abused counterparts found significantly higher health care costs for the former. Intergenerational effects have been noted, with the children of victims of child sexual abuse exhibiting more conduct problems, peer problems, and emotional problems than their peers.A specific characteristic pattern of symptoms has not been identified, and there are several hypotheses about the causality of these associations.Studies have found that 51% to 79% of sexually abused children exhibit psychological symptoms. The risk of harm is greater if the abuser is a relative, if the abuse involves intercourse or attempted intercourse, or if threats or force are used. The level of harm may also be affected by various factors such as penetration, duration and frequency of abuse, and use of force. The social stigma of child sexual abuse may compound the psychological harm to children, and adverse outcomes are less likely for abused children who have supportive family environments.
Physical
Injury
Depending on the age and size of the child, and the degree of force used, child sexual abuse may cause internal lacerations and bleeding. In severe cases, damage to internal organs may occur, which, in some cases, may cause death. Infections
Child sexual abuse may cause infections and sexually transmitted diseases. Due to a lack of sufficient vaginal fluid, chances of infections can heighten depending on the age and size of the child. Vaginitis has also been reported. Neurological damage
Research has shown that traumatic stress, including stress caused by sexual abuse, causes notable changes in brain functioning and development. Various studies have suggested that severe child sexual abuse may have a deleterious effect on brain development. Ito et al. (1998) found "reversed hemispheric asymmetry and greater left hemisphere coherence in abused subjects;" Teicher et al. (1993) found that an increased likelihood of "ictal temporal lobe epilepsy-like symptoms" in abused subjects; Anderson et al. (2002) recorded abnormal transverse relaxation time in the cerebellar vermis of adults sexually abused in childhood; Teicher et al. (1993) found that child sexual abuse was associated with a reduced corpus callosum area; various studies have found an association of reduced volume of the left hippocampus with child sexual abuse; and Ito et al. (1993) found increased electrophysiological abnormalities in sexually abused children.Some studies indicate that sexual or physical abuse in children can lead to the overexcitation of an undeveloped limbic system. Teicher et al. (1993) used the "Limbic System Checklist-33" to measure ictal temporal lobe epilepsy-like symptoms in 253 adults.
