Geriatricians are essential in dementia care because they are uniquely trained to manage the complex web of medical conditions, medications, and age-related changes that accompany cognitive decline. While a general practitioner might focus narrowly on a patient’s blood pressure or diabetes, a geriatrician understands how each of these conditions interacts with dementia and how treatment decisions in one area can trigger cascading problems in another. For example, a person with Alzheimer’s disease who also has heart disease, high blood pressure, and arthritis doesn’t simply need four separate treatment plans—they need a unified approach that accounts for how medications prescribed for one condition can worsen confusion, increase fall risk, or complicate dementia progression.
A geriatrician’s specialized training in aging medicine means they recognize patterns that other doctors might miss. They understand that many symptoms attributed to dementia—confusion, incontinence, wandering, agitation—might actually stem from a urinary tract infection, medication side effect, thyroid problem, or nutritional deficiency. This detective work is not part of standard medical training, yet it often determines whether a person with dementia receives appropriate care or spirals into unnecessary decline.

What Makes Geriatricians Different from General Practitioners in Dementia Management?
A geriatrician’s training goes far beyond understanding dementia itself. These physicians complete additional fellowship training specifically focused on the medical needs of older adults, including how aging changes the body’s ability to metabolize drugs, how chronic diseases accumulate over decades, and how to weigh competing health priorities in a way that honors what matters most to the patient. A general internist or family medicine doctor may see hundreds of dementia patients over their career, but rarely with the depth of geriatric-specific knowledge that shapes every clinical decision. The difference becomes apparent in how they approach medication lists.
An 85-year-old with dementia might arrive at an appointment taking ten or more medications, some of which were started years ago for conditions that may no longer be relevant. A general doctor might continue these medications out of habit or fear of causing harm by stopping them. A geriatrician, by contrast, reviews each medication with a specific question: does this help the person achieve their current health goals, or does it cause more harm than benefit at this stage of life? This process, called deprescribing, often requires specialized knowledge. For instance, aggressive blood pressure medication that lowers a person’s systolic pressure below 130 might increase their fall risk—a dangerous trade-off for someone with dementia. A geriatrician weighs this carefully; a general doctor might not even consider it.
How Geriatricians Address Multiple Medical Conditions Alongside Dementia
Most people with dementia don’t have dementia alone. They have dementia plus osteoarthritis, dementia plus heart disease, dementia plus diabetes. When these conditions exist simultaneously, standard treatment guidelines designed for healthy, cognitively intact older adults often become inappropriate or even harmful. A geriatrician sees this combination as a single, interconnected problem requiring a unified strategy. Consider a real scenario: an 78-year-old woman with vascular dementia also has atrial fibrillation (irregular heartbeat) and takes a blood thinner to prevent stroke. Standard guidelines recommend tight blood sugar control in diabetes. But if this same woman has cognitive impairment and takes pain medications for arthritis, aggressive diabetes management might cause hypoglycemia—dangerously low blood sugar—which can trigger confusion, aggression, or falls.
Her confusion might worsen, and her family might mistakenly think her dementia is progressing faster, when in reality an overly strict diabetes goal is the culprit. A geriatrician would recognize this risk and adjust her diabetes target to be less stringent. A general practitioner following standard diabetes guidelines might not catch it. One significant limitation of geriatric care is availability. There are fewer than 7,000 board-certified geriatricians in the United States for over 50 million people age 65 and older. This shortage means many people with dementia never see a geriatrician and must work with primary care doctors who lack specialized geriatric training. In rural areas, the wait to see a geriatrician can be months, if one is available at all. This reality makes it all the more important for primary care physicians to seek consultation with geriatricians for complex cases.
The Role of Medication Management in Geriatric Dementia Care
Medications are necessary tools in dementia care, but they become increasingly complicated as people age and accumulate health conditions. Older bodies metabolize drugs differently than younger bodies. The liver processes medications more slowly. The kidneys excrete drugs less efficiently. Body composition changes mean drugs that worked at a certain dose twenty years ago might now accumulate to toxic levels. A geriatrician understands these pharmacokinetic changes and adjusts doses accordingly, sometimes prescribing much lower amounts than standard guidelines suggest. Certain medication classes are particularly problematic in dementia.
Anticholinergic drugs—which include some antihistamines, antispasmodics, and even some antidepressants—can significantly worsen cognition in people with dementia and increase confusion, constipation, and urinary retention. A geriatrician knows to avoid these medications or use alternatives. Benzodiazepines, commonly prescribed for anxiety or insomnia, increase fall risk and confusion in older adults with dementia and can actually worsen anxiety over time. Yet these medications are still prescribed to people with dementia by doctors unfamiliar with geriatric-specific risks. A geriatrician would recommend non-medication approaches first—sleep hygiene, structured routines, addressing root causes of anxiety—or choose medications with better safety profiles for this population. The challenge is that medication side effects in people with dementia often look like disease progression. If a person starts a new medication and becomes more withdrawn and apathetic over the next week, the family might assume the dementia is worsening. A geriatrician considers the timeline and looks for iatrogenic causes—problems caused by medical treatment itself—before accepting that the dementia has simply progressed.
When and How to Involve a Geriatrician in Your Care Plan
Not every person with dementia needs to see a geriatrician regularly, but certain situations make geriatric expertise essential. If a person has dementia plus three or more chronic conditions, if they’re taking more than five medications, if they’ve had a recent fall or hospitalization, or if their primary doctor is uncertain about managing complex medication interactions, a geriatrician consultation is warranted. This doesn’t necessarily mean replacing the primary care doctor; rather, the geriatrician provides specialized input that the primary care doctor then implements. Getting a geriatrician consultation typically begins with a referral from your primary care doctor. If your doctor is unfamiliar with geriatricians or seems reluctant to refer, you can ask specifically: “Given my mother’s dementia, multiple health conditions, and medication list, would a geriatrician’s input be helpful?” Most insurance plans cover geriatrician visits, though some require prior authorization.
The first visit usually involves a comprehensive assessment that takes longer than a typical medical appointment—often 90 minutes or more—because geriatricians complete a detailed medication review, assess for geriatric syndromes like falls or incontinence, and consider social factors affecting health. A primary care visit for a medication refill might be 15 minutes; a geriatrician’s initial assessment is thorough. One tradeoff to understand: because geriatricians are in short supply and comprehensive evaluations take significant time, the visits are often longer and the practice might not see as many patients per day. This sometimes means longer wait times for appointments or fewer follow-up visits. In contrast, a primary care doctor sees more patients per day but has less time for depth. The more complex the patient, the more the extra time investment with a geriatrician pays off.
Common Pitfalls: What Happens Without Geriatric Expertise
When people with dementia receive care without geriatric input, preventable harms commonly occur. One frequent mistake is continuing medications designed to prevent diseases that will never manifest. A 90-year-old with advanced dementia starting a statin to prevent a heart attack years down the road receives no benefit—the person is unlikely to live long enough to benefit from stroke prevention, and the medication adds to cognitive burden and side effect risk. Yet statins are often continued out of habit or because stopping them seems risky to the doctor. A geriatrician would review whether this medication aligns with the person’s current goals of care. Another common pitfall is treating numbers rather than symptoms. A blood pressure of 150/90 looks “high” on paper, but if the person is alert, comfortable, and not having strokes, aggressive lowering of that pressure might cause more harm—particularly if it leads to dizziness, falls, or reduced kidney function.
Primary care doctors focused on guideline-directed care might push blood pressure lower and lower; a geriatrician would ask whether this particular patient, with this particular level of dementia, benefits from that approach. Polypharmacy—taking many medications—is a common consequence of care without geriatric oversight. Each specialist the person sees might add a medication for their specific condition without knowing what other drugs the patient takes. A cardiologist prescribes a beta-blocker; a neurologist adds an antidepressant; an orthopedist suggests a pain medication. None of these doctors realize the combination increases fall risk or that one medication interferes with another. Within two years, the person has gone from five medications to twelve. A geriatrician would identify these redundancies and overlaps and work to streamline the medication list.
Behavioral and Psychiatric Symptoms: A Geriatrician’s Approach
Dementia often brings behavioral challenges—agitation, aggression, wandering, or refusal to cooperate with care. A common response is to prescribe antipsychotic medications like risperidone or haloperidol to manage these behaviors. However, antipsychotics in older adults with dementia increase the risk of stroke and death and are recommended only as a last resort after other causes have been explored. A geriatrician knows to investigate the cause first: Is the person in pain from arthritis or an infection? Are they confused because of a urinary tract infection, dehydration, or medication side effect? Are they frightened because they don’t recognize the caregiver or their environment? Are they hungry, uncomfortable, or experiencing constipation? These non-medication causes drive many behavioral symptoms, and a geriatrician systematically rules them out before considering psychiatric medications.
A specific example: an 82-year-old man with Alzheimer’s disease becomes increasingly agitated and aggressive toward his wife over the course of a week. His primary care doctor, seeing the behavioral problem, suggests an antipsychotic. But a geriatrician asks about recent changes: Has he had fever? Any new medications? Changes in urination or bowel habits? Is he eating and drinking? A careful examination reveals a urinary tract infection—the cause of the behavioral change. A course of antibiotics resolves the infection, and the agitation disappears without psychiatric medication. This pattern repeats frequently in geriatric medicine: behavioral symptoms that look like dementia progression are actually reversible medical problems.
Coordinating Care Across Multiple Specialists
As people with dementia age and their medical needs grow more complex, they often see multiple specialists—a cardiologist for heart disease, an endocrinologist for diabetes, a rheumatologist for arthritis. Each specialist focuses on their organ system. A geriatrician serves as a coordinator who ensures these specialists’ recommendations align with each other and with the person’s overall goals of care. Without this coordination, conflicting advice creates confusion and harm.
A geriatrician also understands that what works in younger people with stable cognition might not work in someone with dementia. A dermatologist might recommend twice-daily skin care routines; a geriatrician would recognize that someone with moderate dementia cannot follow complex instructions and would suggest simpler alternatives. A physical therapist might prescribe extensive exercises; a geriatrician would work with them to create realistic routines that the person can actually complete, accounting for fatigue and cognitive limitations. This coordination across specialties, grounded in deep understanding of aging and dementia, is the geriatrician’s essential contribution to the medical team.
