Psychiatric care for adults over 65 isn’t just adult psychiatry with smaller doses. It’s a distinct specialty that accounts for age-related changes in drug metabolism, medical comorbidity, cognitive function, and the unique psychiatric presentations of late life.
According to the Centers for Disease Control and Prevention, depression affects about 7% of adults 65 and older, but the prevalence in primary care and long-term care settings is significantly higher. Late-life mental health is often underdiagnosed because symptoms get attributed to “just aging” — when they’re actually treatable conditions.
Why Older Adults Need Specialized Psychiatric Care
Age-related pharmacology changes
Older adults metabolize medications differently — reduced renal and hepatic function, changed body composition (more fat, less muscle and water), and reduced protein binding all affect drug levels. Starting doses and target doses are different. “Start low, go slow” matters more than at any other age.
Medical complexity
Most older adults take multiple medications for medical conditions. Drug-drug interactions are common, and psychiatric medications may worsen or improve medical conditions. Coordination with primary care matters.
Distinct psychiatric presentations
Depression in older adults often presents with physical complaints, cognitive concerns, and anxiety rather than overt sadness. Anxiety frequently coexists with medical fear and grief. Cognitive symptoms may represent depression, medication effects, sleep apnea, or early dementia — distinguishing them requires expertise.
Cognitive considerations
Some medications used commonly in younger adults (benzodiazepines, anticholinergics, certain TCAs) increase fall risk and cognitive impairment in older adults. Choosing alternatives that don’t carry these risks is part of geriatric expertise.
Common Conditions in Late Life
Late-onset depression
First depressive episode after age 60 — different from depression that’s been present throughout life. Often associated with cerebrovascular changes, medical illness, social isolation, or grief. Treatment is similar to depression at other ages but with attention to medical context.
Cognitive disorders
Mild cognitive impairment, dementia (Alzheimer’s, vascular, mixed), and psychiatric symptoms of dementia (depression, anxiety, agitation, psychosis). Psychiatric symptoms in dementia respond to specific approaches different from primary psychiatric disorders.
Late-life anxiety
Often centered on health concerns, fear of falling, fear of dependence, fear of cognitive decline. Often coexists with depression. Treatment options must consider fall risk and cognitive effects of medications.
Grief and bereavement
Loss of spouse, family members, and friends accumulates in late life. Complicated grief (prolonged grief disorder) is treatable. Distinguishing grief from depression matters clinically.

Evidence-Based Treatment Considerations
Antidepressants
SSRIs are first-line. Sertraline and escitalopram are often preferred for older adults due to favorable interaction profiles. Paroxetine is generally avoided due to anticholinergic effects. Bupropion can be useful when fatigue and apathy predominate. Mirtazapine helps with sleep, appetite, and depression simultaneously.
Anxiolytics
Benzodiazepines are largely avoided due to fall risk, cognitive effects, and dependence. SSRIs/SNRIs and buspirone are preferred for chronic anxiety. Brief situational use may sometimes be appropriate with caution.
Sleep medications
Most prescription sleep medications have problems in older adults. Trazodone at low doses is often preferred. Melatonin and behavioral approaches matter.
Dementia-related symptoms
Psychiatric symptoms of dementia (agitation, paranoia, severe depression) sometimes require atypical antipsychotics with careful risk-benefit consideration. Behavioral approaches always come first.
“Just aging”
Treatable conditions in older adults get dismissed as inevitable parts of aging — leaving patients without help that would clearly benefit them.
Geriatric expertise
Dr. Farkas applies geriatric pharmacology principles, considers medical context, and recognizes age-specific psychiatric presentations.
Real improvement
Properly treated older adults often regain function, mood, and engagement — proving the symptoms were treatable conditions, not destiny.
Common Questions About Geriatric Psychiatry
Can older adults use telepsychiatry?
Most can — research shows telepsychiatry works well for older adults with mild-to-moderate cognitive abilities. Family members can sometimes assist with technology setup. Severe cognitive impairment may require in-person evaluation.
Are psychiatric medications safe for older adults?
When properly selected and dosed, yes. The risks come from inappropriate selection or generic adult dosing. Specialist geriatric expertise reduces risk significantly.
What about cognitive symptoms — is it depression or dementia?
Distinguishing depression-related cognitive symptoms (“pseudodementia”) from actual dementia is a key geriatric psychiatry question. Treatment trials for depression often clarify — true depression-related cognitive symptoms improve with depression treatment. See our related article on Alzheimer’s psychiatric care.
My elderly parent refuses to see a psychiatrist — what now?
Approach matters. Framing care around quality of life, sleep, or specific symptoms (rather than “mental health”) often works better. Including family in initial conversations can help. Telehealth reduces the barrier of office visits.
