Geriatric Psychiatry: Specialized Mental Health Care for Older Adults
Geriatric psychiatry is the subspecialty of psychiatry that focuses on diagnosing and treating mental health conditions in older adults. It occupies an unusual intersection in medicine, drawing on both psychiatric expertise and a deep understanding of how aging, chronic illness, cognitive change, and polypharmacy complicate the clinical picture. For older adults with complex or treatment-resistant mental health conditions, a geriatric psychiatrist can offer a level of evaluation and precision that general psychiatric care often cannot.
This guide explains what distinguishes geriatric psychiatry, when specialist consultation is warranted, and what to know about psychiatric medications in older adults. For an overview of depression, anxiety, and loneliness in the aging population more broadly, see our Mental Health and Aging guide.
A geriatric psychiatrist has completed standard psychiatry residency training and then an additional fellowship specifically in late-life mental health. That additional training covers the neurobiology of aging, late-onset psychiatric disorders, the psychiatric manifestations of neurological conditions like Parkinson’s disease and dementia, the unique pharmacokinetics of older patients, and the intersection of psychiatric symptoms with chronic medical conditions.
Where general psychiatry evaluates a patient’s mental health largely in isolation from their medical context, geriatric psychiatry does the opposite. An older adult presenting with new-onset psychosis may have late-life schizophrenia, or may have Lewy body dementia, or may have delirium from a urinary tract infection, or may have medication toxicity from a recent prescription change. The differential diagnosis requires integrating medical, neurological, and psychiatric knowledge simultaneously. A geriatric psychiatrist is trained for exactly that integration.
Geriatric psychiatrists are also particularly skilled in managing psychiatric symptoms in people with dementia, where behavioral and psychological symptoms, including agitation, hallucinations, aggression, depression, and sleep disturbance, are common and difficult to treat. Medication management in this context requires careful judgment about risk and benefit that is genuinely different from standard psychiatric prescribing.
Most late-life depression and anxiety can be managed at the primary care level or by a general psychiatrist or therapist. But certain presentations are better served by geriatric psychiatric expertise:
When an older adult has failed two or more adequately trialed antidepressants, or when depression is severe, recurrent, or accompanied by suicidal ideation, geriatric psychiatric evaluation can identify contributing factors a general provider may have missed, including underlying neurological disease, medication interactions, or treatment approaches such as TMS or ECT that require specialist oversight.
Behavioral and psychological symptoms of dementia, including agitation, aggression, psychosis, disinhibition, and sleep disruption, require psychiatric management that accounts for the underlying neurological condition. Antipsychotic medications, for example, carry a significant black box warning in people with dementia and must be used with specific clinical judgment about risk and benefit.
Hallucinations or delusions appearing for the first time in a person over 65 have a much broader differential diagnosis than in younger adults. Delirium, medication toxicity, Parkinson’s disease psychosis, and Lewy body dementia all require different management. A geriatric psychiatrist is well positioned to evaluate this picture comprehensively before treatment decisions are made.
Older adults with long-standing bipolar disorder, schizophrenia, or other serious mental illnesses face compounding challenges as their medical complexity increases with age. Many mood stabilizers and antipsychotics require monitoring for kidney function, metabolic effects, and cardiac parameters that become more relevant in older patients. Geriatric psychiatric expertise helps manage these conditions across the biological changes of aging.
Post-ICU syndrome, post-stroke depression, the psychiatric sequelae of a major cardiac event, or the emotional and cognitive aftermath of a delirium episode all benefit from evaluation by someone who understands the neurobiological intersection between medical events and mental health. In the Buncombe County context, Mission Health patients who experience psychiatric symptoms following hospitalization often benefit from specialist follow-up rather than a return solely to primary care.
Prescribing psychiatric medications for older adults requires more care than in younger populations. Several physiological changes affect how drugs behave in the aging body.
Kidney and liver function decline with age, slowing the clearance of medications that would be processed more rapidly in a younger person. Body composition shifts with age, with more fat tissue and less water relative to body weight, affecting how drugs distribute through the body. The blood-brain barrier becomes more permeable, increasing sensitivity to medications that affect the central nervous system. And older adults are typically taking more medications, creating a more complex environment for drug interactions.
The practical consequences are real:
- Standard doses may be too high. A dose of an antidepressant or anti-anxiety medication that is appropriate for a 50-year-old may produce toxic levels or excessive side effects in an 80-year-old. Start low, go slow is not a cliche in geriatric prescribing.
- Side effect profiles matter more. Antidepressants with anticholinergic effects (confusion, constipation, urinary retention, dry mouth) that are merely inconvenient in younger adults can cause significant harm in older ones. SSRIs have their own concerns in older adults, including hyponatremia (low sodium) and increased fall and bleeding risk. Benzodiazepines, frequently prescribed for anxiety and sleep, carry substantially elevated risks of falls, cognitive impairment, and dependence in older adults and are on the Beers Criteria list of medications to avoid in this population.
- Response time may be longer. Older adults sometimes take longer to show a therapeutic response to antidepressants than younger adults, requiring patience before concluding that a medication is not working.
- Drug interactions compound with polypharmacy. The more medications someone takes, the more opportunities for interactions that affect efficacy and safety. A geriatric psychiatrist or geriatric pharmacist reviewing the full medication list alongside psychiatric prescribing is valuable precisely because this complexity exceeds what any single specialist can track reliably.
Psychotherapy is effective for late-life depression and anxiety and is underused in older adults. Cognitive behavioral therapy, problem-solving therapy, and behavioral activation all have strong evidence for this population. For older adults who are concerned about medication or cannot tolerate it well, therapy is a legitimate first-line treatment rather than a consolation prize.
Grief-focused therapy is a specific form of treatment for complicated or prolonged grief, distinct from standard CBT, that has been developed for and studied in older populations. For someone who has experienced significant loss and whose grief has persisted in a way that is disabling, this is worth seeking specifically rather than accepting general therapy that may not address the particular nature of late-life grief.
The combination of therapy and medication outperforms either alone for most late-life depression presentations, particularly when social factors or situational stressors are significant contributors.
Buncombe County has several access points for psychiatric care with geriatric capability. Pisgah Institute, the largest behavioral health practice in Western North Carolina, includes psychiatrists, psychiatric nurse practitioners and physicians assistants, doctoral psychologists, and licensed therapists, and currently accepts new patients. MAHEC’s Psychiatry and Behavioral Health program at 125 Hendersonville Road offers evaluation, medication management, and TMS therapy. Apogee Behavioral Medicine, at 77 Central Avenue in Asheville, specifically lists geriatric medication management as a service area.
