Getting an elderly parent evaluated typically starts with their primary care doctor, who can perform initial screenings and refer to specialists if needed. The process doesn’t have to be complicated, but it does require some preparation, especially if your parent is reluctant or if you’re unsure what kind of evaluation they need. Here’s how to move through it step by step.
Recognizing When an Evaluation Is Needed
Before scheduling anything, it helps to be specific about what you’ve noticed. Doctors will ask you for concrete examples, so keeping a mental (or written) log of changes makes the appointment far more productive. Changes worth noting include difficulty managing medications or finances, getting lost on familiar routes, personality shifts, repeated questions in the same conversation, unexplained weight loss, and new trouble with balance or walking.
Some risk factors also raise the priority level. A history of type 2 diabetes, stroke, or depression increases the likelihood of cognitive decline. Being over 80 is itself a risk factor. If your parent has been the victim of financial fraud or had a car accident that seemed out of character, those are signals that something may have already progressed beyond normal aging. The key threshold is this: if you, your parent, or anyone close to them has noticed changes in memory, thinking, or behavior, that alone is enough reason to pursue a formal assessment.
Starting With the Primary Care Doctor
Your parent’s primary care physician is the right first call. You don’t need a specialist referral to begin. At a routine visit, the doctor can run brief cognitive screening tests that take just a few minutes. The most common is the Mini-Cog, which asks the patient to remember three words and draw a clock face. It sounds simple, but it reliably picks up problems with short-term memory and spatial reasoning, both early markers of dementia.
If the results suggest mild impairment, the doctor may use a more detailed tool like the Montreal Cognitive Assessment (MoCA), which tests a broader range of abilities: abstract thinking, mental flexibility, language, attention, and recall. An older test called the MMSE is still used in some offices, though it’s most effective at detecting moderate to severe impairment rather than catching early changes.
These screenings aren’t a diagnosis. They’re a starting point that tells the doctor whether to dig deeper.
What a Full Geriatric Assessment Covers
If screening raises concerns, the next step is often a comprehensive geriatric assessment. This is a thorough, multidisciplinary evaluation that looks at far more than memory. It examines physical health, cognitive function, mood, medication use, social support, financial stability, living environment, and your parent’s own goals for their care.
A typical assessment evaluates two categories of daily functioning. Basic activities of daily living are the physical essentials: bathing, dressing, eating, using the toilet, and grooming. Instrumental activities of daily living are the more complex tasks that require planning and organization: cooking, managing money, taking medications correctly, doing laundry, shopping, and using a phone. Decline in instrumental activities usually appears first and is one of the clearest signs that someone is losing the ability to live independently.
The assessment also screens for depression (often using a standardized questionnaire), reviews all current medications for dangerous interactions or unnecessary prescriptions, evaluates fall risk, and addresses safety concerns like driving. Expect the visit to take about 60 minutes, and the doctor will want to speak with both your parent and someone who knows them well, like you, a spouse, or another caregiver.
Choosing the Right Specialist
A geriatrician is often the best first specialist when you’re not sure what’s going on. Geriatricians are trained to evaluate the full picture of aging: recurrent falls, blood pressure changes, weight loss, depression, social isolation, bone health, and cognitive decline all at once. They can also serve as a primary care physician, managing your parent’s overall health rather than treating a single condition.
A neurologist becomes the right choice when a specific diagnosis like Alzheimer’s disease, another form of dementia, or a movement disorder like Parkinson’s is suspected. Neurologists typically order blood tests to rule out reversible causes of cognitive problems and may request brain imaging to check for signs of stroke, bleeding, or tumors. If dementia is confirmed, the neurologist manages treatment aimed at slowing progression.
In practice, the path often runs through both: a geriatrician evaluates broadly, then refers to a neurologist if the cognitive picture points toward a specific neurological condition.
Blood Tests That Rule Out Treatable Causes
One of the most important parts of any evaluation is checking for reversible conditions that mimic dementia. A surprising number of cognitive symptoms in older adults come from problems that can be treated once they’re identified.
Standard blood work includes vitamin B12 levels (deficiency causes confusion and memory problems), thyroid function tests (both overactive and underactive thyroid can affect thinking), a complete blood count, blood glucose, and kidney and liver panels. Doctors may also run a toxicology screen to check for medication side effects or alcohol-related issues, and in some cases test for infections known to affect the brain. If these tests reveal a deficiency or hormonal imbalance, treating it can significantly improve or even resolve cognitive symptoms.
How Medicare Covers the Evaluation
Medicare Part B covers a dedicated cognitive assessment and care planning visit when a provider identifies signs of impairment. This is a separate, billable visit (not just a brief screening during a checkup) that includes a full cognitive exam, a functional assessment of daily living skills, medication review, safety evaluation, and discussion of advance care planning. The visit typically lasts 60 minutes and requires an “independent historian,” meaning someone other than the patient (usually a family member like you) needs to be present to provide context.
Standard Part B coinsurance and deductible apply, so it’s not completely free, but the bulk of the cost is covered. This visit can be scheduled separately from the Annual Wellness Visit, or combined with it on the same day. If your parent has Medicare, this coverage exists specifically for the kind of evaluation you’re looking for.
Getting Involved When Your Parent Resists
Many adult children face a frustrating reality: they can see the decline, but their parent insists nothing is wrong. A few strategies help.
Frame the appointment around something less threatening. Rather than saying “I think you need a memory test,” suggest a general checkup or tie it to something concrete like a medication review or a fall they had recently. Many doctors are willing to work cognitive screening into a routine visit without making it the stated purpose.
You can also call your parent’s doctor in advance. Privacy laws prevent the doctor from sharing your parent’s medical information with you without permission, but they do not prevent you from giving information to the doctor. You can call or write a letter describing the specific changes you’ve observed. The doctor can then raise those issues naturally during the next appointment.
Navigating Privacy and HIPAA
If your parent is mentally competent, they control who has access to their health information. There are several ways to make sure you can stay involved in their care.
The simplest option is a written authorization. Your parent signs a form at the doctor’s office directing the provider to share their medical information with you. This can be as broad or narrow as your parent wants. A second option is for your parent to designate you as their personal representative through a healthcare power of attorney, which gives you legal authority to make medical decisions and access records. Whether this is recognized depends on your state’s laws.
If your parent hasn’t signed any paperwork but doesn’t object to your presence, doctors are generally permitted to share relevant information with family members who are involved in the patient’s care. And if your parent becomes incapacitated, a provider can share information with you if they judge it to be in your parent’s best interest.
The practical advice: get a healthcare power of attorney and a HIPAA authorization signed while your parent is still willing and able. These documents become much harder to obtain after cognitive decline has progressed.
Preparing for the Appointment
The evaluation will go more smoothly if you come prepared. Bring a complete list of your parent’s current medications, including over-the-counter supplements and dosages. Write down the specific changes you’ve noticed, with approximate dates when they started. Note any recent falls, hospitalizations, or new diagnoses. If your parent has had previous cognitive testing, bring those results so the doctor can compare.
Also prepare a list of your parent’s daily routine: what they can still do independently and where they’ve started needing help. This functional snapshot is one of the most valuable things you can provide, because your parent may perform well on a brief office screening while struggling significantly at home. Your observations fill in the gaps that a 30-minute appointment can’t capture.
