Victims of severe traumatic elder abuse are more likely to be female, suffer from a neurological or mental disorder, and to abuse drugs or alcohol, according to research published recently in the Journal of the American Geriatrics Society.

“Past studies have shown that alcohol abuse by the perpetrator plays a substantial role and is strongly associated with physical abuse,” says Lee Friedman, assistant professor of environmental and occupational health sciences at the University of Illinois at Chicago and lead author of the study. “Our findings indicate that alcohol abuse among the victims may be an important contributing factor as well.”

Twenty-nine percent of abuse victims in the study tested positive for alcohol, compared to 13 percent of controls.

Eighty-five percent of the perpetrators were family members or intimate partners. In most cases, the abuse was not identified until after the admission process or several days into hospitalization.

The failure of medical staff to properly identify abuse victims and contact adult protective services in the majority of cases shows that clinicians need to better understand elder abuse, Friedman said.
