Substance Abuse and Misuse in Older Adults
Surprising numbers of older adults struggle with drug and alcohol issues. Would you know the warning signs specific to this demographic?
Substance abuse problems have a terrible impact on social relationships, health, and emotional well-being. They can lead to other serious illnesses, worsen medical conditions, and increase healthcare costs. However, substance use is often unrecognized as an issue, let alone a priority issue, for older adults.
In fact, a substantial and growing percentage of older adults knowingly or unknowingly misuse alcohol, medications, and illegal substances. And as the number of older adults in the United States surges over the next quarter century, so will the number of elders with substance abuse problems. There were 1.7 million substance abusers over the age of 50 in 2001, a number that is expected to more than double to 4.4 million by 2020, according to statistics from Drug and Alcohol Dependence.
Demographics and Prevalence
A few older adults also use illegal substances, mostly marijuana. The most recent national study on substance use found that 1.7% of older adults use illegal substances, up from less than 1% a decade ago. This appears to support the widespread expectation that the use of illegal substances by older adults will increase as the baby boomer generation ages. According to David Oslin, MD, a geriatric psychiatrist at the University of Pennsylvania, both a history of substance dependence and continued use will have physical and mental health consequences for this cohort as it ages.
Physical and Psychological Aspects of Substance Abuse Among Older Adults
The misuse of medications is far more common among older adults because they have more chronic medical conditions and are prescribed more medications. Adjustments to allow for correct, age-appropriate dosages and information on contraindications are often missing in the communication between a prescribing physician and the older patient. Interactions between medication and alcohol are of particular concern among older adults as they can cause serious medical and psychological problems.
Alcohol Misuse and Abuse
Prescription and OTC Medication Misuse
Many older adults have several physicians prescribing different medications who may be unaware of the multiple medications the patients are taking, which could lead to dangerous interactions. In addition, some healthcare providers lack training and education about working with older adults and therefore may prescribe inappropriate medications or dosage.
Commonly misused prescription and OTC medications include painkillers, antianxiety drugs, sleeping pills, diet aids, and decongestants. Antipsychotic drugs, which are commonly and often inappropriately prescribed to older adults with behavioral problems, are of particular concern because their continual use leads to problematic and sometimes dangerous symptoms and side effects.
Illegal Drug Use
Lifelong recreational drug users—particularly those who use marijuana—may find their drug use becoming more problematic due to changing physiology and life circumstances that increase isolation, such as retirement or no longer having child-rearing responsibilities or nearby friends to maintain regular, healthy interpersonal socialization.
Hard-core drug addicts who manage to survive into old age may suddenly discover with great sadness that they have lost life’s major opportunities and seek to redeem themselves by reconnecting with long estranged family and finding some way to make a productive contribution to society in their final years. Of course, those who continue to abuse drugs such as cocaine and heroin are at a very high risk of physical decline resulting in disability and premature death.
Barriers to Identification and Treatment
Even if providers are aware of the need to look for signs of substance abuse and misuse, they often lack the professional training or skills to recognize them in the older population. Signs and symptoms of alcohol abuse and misuse are similar to those of other common medical conditions and to what is often mistakenly believed to be part of the normal aging process. They include memory problems, fatigue, sleep problems, confusion, depression, anxiety, and irritability. Signs of medication misuse include mood changes, irritability, lack of energy and concentration, loss of short-term memory, and general loss of interest.
In addition, many retired elders drink unnoticed at home or in local bars or social settings. They are not nearly as likely to get in trouble with the law or their places of employment as younger people. Many older adults and their family members don’t realize that they have a drinking problem or are misusing medications. And when they do, they often feel shame or guilt and don’t want to be stigmatized as alcoholics or drug addicts are. Family members may also fail to view drinking or medication abuse as harmful. For all these reasons, many older adults with substance use problems don’t seek the help they need.
As a result of failures of screening, lack of training in the signs and symptoms of substance misuse, stigma, ageist assumptions, and ignorance about substance abuse problems among older adults, such problems often go undiagnosed and untreated. In 2001, only 11.9% of an estimated 1.7 million older adults with substance abuse treatment needs had received treatment within the previous year.
Addressing Substance Abuse Problems in Older Adults
Identification and Treatment of Alcohol Misuse and Abuse
Psychosocial treatments including interventions, such as cognitive behavioral therapy and motivational interviewing, as well as supportive, nonconfrontational approaches and separate groups for older adults, are likely to be effective. Fred Blow, MD, of the University of Michigan, commented at the previously mentioned American Academy of Addiction Psychiatry meeting that in his studies he found it difficult to get older adults to talk about alcohol-related problems, although they would discuss other issues, such as social interactions, family activity, and general concerns. The implication of this finding is that therapists may need to explore their patients’ concerns about these areas of life to help them find the motivation to deal with their drinking problems.
Peer self-help approaches, such as Alcoholics Anonymous, are often better when they are comprised exclusively of older adults. More specialized treatment designed to adapt existing outpatient, detoxification, inpatient, residential, and recovery services models are also useful approaches for older consumers depending on the level of need. While little research addresses medication interventions for alcohol abuse, naltrexone reduces the craving for alcohol and has been shown to reduce alcohol relapse. It is critical to understand that there is no one-size-fits-all approach. Treatment and other interventions must be tailored to the needs of the individual.
Managing Medication Misuse
There is limited research on effective treatment interventions. Possible promising programs include hospital discharge programs, prescription guidelines for providers, and medication review procedures in settings such as home care and nursing homes. Brief informational and intervention sessions represent viable and nonthreatening opportunities to provide support and relief.
Electronic medical records and databases that connect the information systems of physicians and pharmacists may also prove helpful.
• improving access via increased service capacity and offering services in home and community-based settings where older adults congregate, such as senior centers and naturally occurring retirement communities;
• improving quality of care, including training and broadening dissemination of effective practices;
• integrating substance abuse, health, mental health, and aging services to provide comprehensive care tailored to the needs of the individual consumer who presents with co-occurring, multiple needs;
• building a clinically and culturally competent workforce through education and training of providers, increasing the supply of competent providers, especially those who are bilingual and culturally competent, and using older adults in peer-to-peer service roles more extensively;
• increasing support for family caregivers, including education about medication management and signs of alcohol and drug abuse;
• providing public education to address ageism, stigma, ignorance, and fears about treatment and its effectiveness;
• improving research on effective prevention, intervention, and recovery support strategies;
• designing finance models that support best practices, integrated service delivery, parity, and incentives to enter the workforce; and
• developing governmental and private sector readiness including leadership, planning, and program development.
It is of utmost importance to mobilize resources and prepare for the significant impact that the growth of the aging population will have on our mental health and substance abuse delivery systems. To adequately address the need, our supporting systems need to join forces now to advocate for appropriate planning and funding. With our unified voice we can make a difference in the lives of elders with behavioral problems.
