Sexual mistreatment is the least common type of elder abuse, according to the U.S. Department of Justice (DOJ) and the WHO. Only 2% of older adults and less than 1% staff reported cases of sexual abuse in a 2020 study from the WHO.
This does not necessarily mean that elder sexual mistreatment is rare, though. A CNN report noted that elder sexual abuse often goes unreported — particularly when an elder suffers from mental impairments like dementia.
