During a neurological examination for dementia, a clinician checks movement, reflexes, strength, coordination, sensation, eye movements, speech, gait, and balance. The clinician may also ask simple questions to assess memory, thinking, orientation, and mood. The examination is one part of a broader dementia assessment, not a stand-alone test. Results are considered alongside symptom history, daily functioning, cognitive testing, medication review, and sometimes laboratory tests or brain scans.

Where the examination fits in a dementia assessment
Before or alongside the examination, the clinician asks about changes in memory, behavior, judgment, and everyday abilities. The discussion also covers medical conditions, medications, and when symptoms began. A family member or friend may provide useful context.
According to the Alzheimer's Association's overview of diagnostic testing, someone close to the patient can describe changes in thinking and daily function over time. This history matters because the neurological examination captures performance during one appointment. It cannot, by itself, show how abilities have changed at home or determine the cause of those changes.
What physical abilities does the clinician check?
The clinician looks for patterns in how the nervous system controls the body. The examination may include checks of: These checks can involve following a finger with the eyes, pushing against the clinician's hands, touching a finger to the nose, or responding when the skin is lightly touched. The exact examination depends on the person's symptoms and abilities.
Movement is also important. The clinician may watch the person stand from a chair, walk, turn, and maintain balance. Mayo Clinic's Alzheimer's diagnosis guidance explains that movement findings can help distinguish Alzheimer's disease from other neurological conditions.
- Reflexes
- Muscle strength and tone
- Coordination
- Sensation
- Eye movements
What happens during the mental-status portion?
A mental-status assessment examines memory and other thinking abilities. The clinician may ask the person to identify the date or location, remember information, answer simple questions, or solve a short problem. Mood may also be assessed because emotional symptoms can affect how a person thinks and functions.
Mayo Clinic describes these checks as part of a neurological examination's mental-status assessment. This portion complements the physical examination; it does not replace it. A person may have noticeable cognitive difficulty without abnormal strength or reflexes, while movement findings may point toward another or coexisting neurological condition.
What can the findings reveal—and what can't they prove?
The examination helps clinicians look for signs associated with stroke, Parkinson's disease, brain tumors, or hydrocephalus, which involves fluid buildup in the brain. Such conditions may cause or accompany problems with memory and thinking. However, no single reflex, walking test, or mental-status answer diagnoses dementia.
The clinician interprets the overall pattern together with the person's history, cognitive and functional testing, and other examination findings. The broader assessment may also uncover dementia-like symptoms related to medication effects, thyroid disease, vitamin deficiencies, depression, delirium, sleep apnea, or excessive alcohol use. Some of these contributors may be treatable, which is why a complete evaluation matters.
What may happen after the examination?
The clinician may order laboratory tests or recommend further cognitive and functional assessment. These steps help investigate other explanations and measure how thinking problems affect daily activities. MRI or CT imaging may be ordered when the findings warrant it.
Such scans can help identify tumors, strokes, injuries, or fluid buildup, but they do not independently diagnose Alzheimer's dementia. To prepare for the appointment, bring or write down: If possible, ask that person to attend. Their account may help the clinician compare what happens during the appointment with changes observed over time.
- Current symptoms and when they began
- Examples of changes in everyday tasks or behavior
- Medical conditions and previous evaluations
- All medications being taken
- Observations from a relative or friend who knows the person well
