A functional assessment for dementia examines how changes in thinking affect a person's ability to manage everyday life. It covers self-care, household tasks, decision-making, safety, and the support the person needs. The assessment is one part of a broader clinical evaluation, not a stand-alone test that diagnoses dementia, according to the Centers for Medicare & Medicaid Services. Its practical purpose is to identify what the person can still do, where difficulties arise, and what help may be appropriate.

Which daily activities are assessed?
Clinicians consider basic activities of daily living, often called ADLs. These include washing, eating, dressing, and using the bathroom. They also examine instrumental activities of daily living, or IADLs. These more complex tasks include cooking, shopping, cleaning, and completing household chores.
The National Institute on Aging explains that instrumental activities often become difficult earlier, while basic self-care is more often affected in moderate or advanced disease. The assessment looks at the help required, not simply whether a task gets done. A person might still prepare food, for example, but need reminders or supervision. Details like these reveal limitations that a simple yes-or-no answer could hide.
How does the clinician gather information?
The visit usually includes a detailed history and examination. The clinician may ask how the person handles routines, whether abilities have changed, and what assistance is already in place. A spouse, guardian, or another knowledgeable person may provide additional information. CMS calls this person an independent historian because someone with cognitive impairment may not give a complete or reliable account of recent changes.
CMS includes an independent historian in its description of a cognitive-assessment visit. The clinician may also use a standardized staging instrument, such as Functional Assessment Staging, known as FAST, or the Clinical dementia Rating. These tools help organize findings about function and dementia severity. The functional portion also considers decision-making capacity.
What else is evaluated?
Daily tasks do not exist in isolation. The wider assessment reviews medicines that could carry higher risks and screens for behavioral or emotional symptoms, including depression and anxiety. These issues may influence both functioning and care needs. The clinician also examines practical safety concerns, including safety at home and motor-vehicle operation.
The aim is to identify specific risks rather than assume that every person with cognitive changes has the same limitations. Available social support matters as well. The assessment considers caregivers' knowledge, needs, and willingness to help. This can show whether a plan is realistic or depends on assistance that is unavailable.
How can you prepare for the appointment?
Bring concrete examples of changes rather than broad descriptions such as "things are getting worse." Focus on what happened, how often it happened, and whether someone had to step in. Useful notes may cover: Include abilities the person has retained, not only problems. This gives the clinician a more balanced picture and can help preserve independence where support is not yet needed.
- Tasks the person completes independently
- Tasks that now require reminders, setup, supervision, or hands-on help
- Recent changes in cooking, shopping, cleaning, dressing, eating, or bathroom use
- Concerns about home safety or driving
- Current medicines and observed mood or behavior changes
What happens after the assessment?
The findings inform a written care plan addressing functional limitations and symptoms. According to CMS, the plan may include education and referrals to services such as rehabilitation, adult day programs, or support groups. Functional measures have limits.
Many rely heavily on reports from the person and someone close to them, and they may overlook personally meaningful social, emotional, or psychological aspects of daily life. The National Institute on Aging identifies these limitations in common ADL and IADL measures. Before leaving, ask for the written care plan and identify which referral, support change, or safety step should happen first.
