Substance Use Disorders in the Elderly
Substance use disorders in older adults remains lower than in younger adults; however, the prevalence is rising in the elderly population. In the United States, the lifetime prevalence of an alcohol use disorder among persons age 65 and older is 16.1%. Studies of Veteran’s Administration nursing home residents have found that 29% to 49% of those admitted have a lifetime diagnosis of alcohol use disorder. A sizable proportion of the elderly acknowledge driving under the influence. In 2013, 1.5% of the elderly had used illicit drugs. The number requiring treatment for substance abuse is expected to double by 2020. The populations with the fastest increase in opiate mortality are those age 55 and older, including those 65 and older. This chapter presents the epidemiology of substance use among older adults and discusses issues related to elders’ substance use, including use in nursing homes, impaired driving and arrests, use of non-prescription medications, screening for substance use, and treatment.
