Bring a written family history to your 2026 brain health review and ask the clinician to add it to your dementia risk plan. The visit should record who was affected, set a cognitive baseline, and turn risk into clear next steps.
Family history here means Alzheimer's disease in a parent or sibling, called first-degree relatives. A dementia risk plan uses that history plus current health and thinking skills to guide monitoring and prevention. History raises risk but does not decide the future.

What family details should you bring?
Write down each affected parent or sibling and what you know about symptoms and timing. Having a parent or sibling with Alzheimer's raises personal risk.
Risk rises further with more than one affected first-degree relative, reports the Alzheimer's Association in its genetics information from the Alzheimer's Association. Bring these items to the visit: Only rare early-onset Alzheimer's comes from single inherited mutations in APP, PSEN1, or PSEN2. Those mutations virtually guarantee disease, often in a person's 40s to 50s, reports the Alzheimer's Association.
- which parent or sibling had Alzheimer's, and how many relatives were affected
- approximate age when memory or thinking problems began
- prior diagnoses, head injury, stroke, and current medicines
- one family member or friend who has noticed recent changes
What will the review do with that history?
The workup should record family history plus current symptoms and prior conditions. It should include brief cognitive testing and an informant report from someone who knows you well. That combination sets a baseline for future comparison, describe NIA and Alzheimer's Association MCI guidance.
Bring examples from daily life, not only test worry. Note missed bills, lost steps in recipes, driving problems, or word loss. Ask what will be rechecked, when, and what change should prompt an earlier visit.
Should you seek genetic or biomarker testing?
APOE ε4 is the main late-onset risk gene to discuss. Inheriting one copy raises late-onset Alzheimer's risk and two copies raise it more. About 15–25% of people carry one copy and 2–5% carry two, states the National Institute on Aging in its genetics fact sheet from the National Institute on Aging.
APOE ε4 is a risk factor, not a diagnosis. Many carriers never develop Alzheimer's and many patients lack ε4, so genetic tests alone cannot predict who will get disease, states the same NIA fact sheet. For symptoms, ask about high-accuracy blood tests. In July 2025, the Alzheimer's Association said tests with at least 90% sensitivity and specificity may substitute for PET or spinal-fluid testing in specialist evaluation of cognitively impaired patients.
What can you act on despite family risk?
Many dementia cases link to factors you can manage. The 2024 Lancet Commission estimated about 45% of dementia cases worldwide are associated with 14 modifiable factors, summarized by Dementia Australia in its prevention and risk-reduction discussion paper from Dementia Australia. Listed factors include hypertension, hearing loss, high LDL, diabetes, smoking, obesity, depression, and vision loss.
Ask for a vascular and sensory check at the review. Control blood pressure, cholesterol, and blood sugar as advised. Treat hearing and vision loss, stop smoking, stay active, eat a balanced diet, protect sleep, and seek care for depression.
How do you keep the plan current?
Use the 2-year U.S. POINTER trial as a model for structure. It enrolled 2,111 adults ages 60–79 at elevated risk and found structured diet, exercise, cognitive, and vascular-health support improved cognition more than self-guided advice, announced the Alzheimer's Association in its study results announcement from the Alzheimer's Association.
Ask for one written plan with diet, activity, cognitive, vascular, hearing, vision, and mood steps. Set dates for repeat cognitive testing and informant input. Bring updated medicines, blood-pressure readings, and hearing and vision notes to each follow-up.
