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. 
More good news is that drug use and addiction are preventable. Results from NIDA-funded research have shown that prevention programs involving families, schools, communities, and the media are effective for preventing or reducing drug use and addiction. Although personal events and cultural factors affect drug use trends, when young people view drug use as harmful, they tend to decrease their drug taking. Therefore, education and outreach are key in helping people understand the possible risks of drug use. Teachers, parents, and health care providers have crucial roles in educating young people and preventing drug use and addiction.
The NBHQF provides a mechanism to examine and prioritize quality prevention, treatment, and recovery elements at the payer/system/plan, provider/practitioner, and patient/population levels. The NBHQF is aligned with the NQS in that it supports the three broad aims of better care, healthy people/healthy communities, and affordable care. However, it was specifically broadened to include the dissemination of proven interventions and accessible care. The latter concept encompasses affordable care, along with other elements of care accessibility, including the impact of health disparities.
