Our aging global population has the potential to enrich our communities, strengthen intergenerational relationships, and help preserve our cultural heritage. However, to realize this promise, our aging population needs a group of professionals such as geriatric psychiatrists who are trained to care for older adults with mental health, addiction, and other neuropsychiatric problems. Such geriatric mental health specialists can help provide crucial expertise and support to primary care providers and allied health professionals, but are currently an underutilized resource. Here, we present a set of recommendations for primary care providers seeking specialist support for older adult patients with neuropsychiatric symptoms or disorders.
The proportion of older adults is projected to increase from 12 percent to 22 percent of the world’s population by 2050. Given that neuropsychiatric disorders affect over 20 percent of older adults, contributing to 6.6 percent of total disability worldwide, there is a strong case for improving access to geriatric psychiatry. While the overall burden of neuropsychiatric disease in older adults is high, epidemiological studies show variable prevalence of specific mental health disorders. For example, Volkert et al.’s 2013 study of the early 2000s reported rates of 33 percent for anxiety disorders, 17 percent for affective disorders, 12 percent for substance use disorders, and 5 percent for psychosis for older adults in Europe and North America.
Despite high rates of psychiatric disorders among older people, studies show disproportionately low use of mental health specialty care, such as geriatric psychiatry, in this population. This was true in the early 2000s, when Garrido et al. investigated mental health care (MHC) utilization among community-dwelling older adults in the U.S. and found that just 6.5 percent of them received MHC per year, with the majority of patients with major depressive disorders or anxiety disorders going without any MHC. Notably, 17 percent of respondents did not receive MHC but felt they needed it, especially those with lower self-care ability. Similarly, the most recent results of a Substance Abuse and Mental Health Services Administration (SAMHSA) national survey estimated that only 46.3 percent of older adults with any mental illness received mental health treatment.
Receipt of mental health care by a mental health specialist typically depends on referrals from another provider. In one small study in New York, the majority of referrals to geriatric psychiatry were from primary care physicians, and the most cited reasons for referral were problem behaviors, psychosis, depression, anxiety, or a loss of function due to cognitive impairment. The majority of patients referred to geriatric psychiatrists had a diagnosis of a neurocognitive disorder. A larger national study found that patients with established mental health diagnoses and patients with psychotic disorders were more likely to be referred to psychiatry by their primary care physicians than to be treated within primary care. Depressive or anxiety disorders did not affect the likelihood of referral significantly. Another review of data from a nursing home population found that agitation, disinhibition, and aberrant motor behavior were the most common neuropsychiatric symptoms among patients referred. At this point, it appears that psychosis and neuropsychiatric symptoms of dementia are the most common reasons for referral to geriatric psychiatry.
Greater awareness of the expertise of geriatric psychiatrists may help increase appropriate referrals and improve access to effective care for the growing number of older adults whose quality of life is impaired by mental health, neurocognitive, and addiction problems.
Navigating the complexities of geriatric mental health care can be challenging, with numerous factors influencing the decision-making process for a referral to geriatric psychiatry. Below are guidelines for clinicians considering a referral.
Family members, caregivers, and primary care providers have a key role in the process of recognizing when an older person is struggling with a mental health, neurocognitive, or addiction problem and helping them get effective care. A variety of consulting specialists can help, including general psychiatrists, consultation-liaison and collaborative care psychiatrists, home-based primary care programs, geriatricians, neurologists, neuropsychologists, clinical psychologists, social workers, occupational therapists, geriatric pharmacists, chaplains, and palliative care providers. Referrals to geriatric psychiatrists – specialists who are uniquely qualified to care for older individuals with mental health problems – may be particularly useful but can be challenging. In the setting of a national shortage of psychiatrists – and an even more critical shortage of geriatric psychiatrists and other geriatric mental health professionals – primary care providers remain on the front lines of identifying, managing, and coordinating care for older adults with mental health needs. The tools provided in this brief overview are designed to support this essential work.
