A functional assessment shows how well a person manages everyday tasks and whether recent changes threaten independence. It can support a dementia evaluation, but it cannot diagnose Alzheimer's disease or another dementia by itself. Clinicians interpret functional results alongside medical history, examinations, cognitive testing, and sometimes imaging, laboratory, or biomarker tests, according to the Alzheimer's Association overview of diagnostic testing. Ask your doctor what the findings show, what they do not show, and what should happen next.

Which abilities changed, and when?
Ask the doctor to identify the specific tasks that have changed. Functional decline is central to a dementia diagnosis, so timing, previous ability, and effects on independence matter.
Useful questions include: Bring concrete examples. "Two bills were paid twice this month" gives the doctor more information than "finances seem harder." The Alzheimer's Association clinical guideline recommends examining which daily functions changed and whether those changes interfere with independence.
- Which tasks are harder now?
- When did the change begin?
- Was the decline gradual, sudden, or inconsistent?
- Does the person need reminders, supervision, or hands-on help?
- Is the change affecting independent living?
Did the assessment cover the right tasks?
Ask whether the assessment covered instrumental activities of daily living, often called IADLs. These are complex tasks such as managing finances and medications, preparing meals, driving, using technology, working, and pursuing hobbies. It should also consider basic activities of daily living, including bathing, dressing, and toileting.
A person may struggle with complex tasks while still managing basic personal care, so the distinction helps describe the level of impairment. Ask which standardized tool was used and what the score means for this individual. Tools measure different functions and stages. For example, the functional Activities Questionnaire can help with an initial IADL assessment but is not suited to tracking decline beyond mild-to-moderate dementia.
Could another condition explain the result?
Ask what the clinician has done to check for reversible or treatable contributors before labeling the problem as dementia. The NICE dementia guideline advises clinicians to investigate other possible explanations for cognitive and functional decline.
Ask specifically about: A low functional score does not reveal why someone is struggling. Pain, poor hearing, fatigue, unfamiliar technology, or medication effects may influence performance, so the score needs clinical context.
- Delirium or infection
- Depression
- Hearing or vision impairment
- Medication effects
- Thyroid problems or vitamin deficiencies
Who should help describe the changes?
Ask whether a family member, friend, or other reliable informant should contribute to the history. When possible, current guidelines recommend gathering information from both the person being evaluated and someone who knows them well. The informant should describe observed changes rather than offer a diagnosis.
Helpful details include missed medications, spoiled meals, unexplained purchases, new navigation problems, or growing dependence on reminders. The doctor should also consider the person's long-standing habits and responsibilities. Someone who never handled household finances cannot show a decline in that task, while difficulty with a familiar hobby or work routine may be more revealing.
What safety steps and support are needed now?
Ask whether the findings raise immediate concerns about medication errors, driving, getting lost, or hazards at home. Then request specific guidance about supervision, environmental changes, and referrals rather than waiting for a final diagnostic label.
Questions to ask include: If Medicare applies, ask whether a cognitive assessment and care-planning visit is appropriate. The Centers for Medicare & Medicaid Services guidance describes a service that can address basic and instrumental activities, decision-making capacity, safety, caregiver needs, referrals, and a written care plan.
- Is it safe for this person to manage medications alone?
- Should driving or navigation be assessed?
- What home modifications are appropriate?
- Does the caregiver need training or additional help?
- When should function be reassessed?
