To track family history of Alzheimer's in a dementia prevention plan after a stroke, record parents, siblings, half-siblings, children, grandparents, aunts, uncles, nieces, nephews and any Alzheimer's or dementia diagnosis, then save that pedigree with the Surgeon General's My Family Health Portrait tool and share it with the post-stroke care team. The team uses that history plus cognitive screening to set follow-up and vascular prevention steps.
Alzheimer's disease is a progressive brain disorder that impairs memory and thinking. After stroke, dementia risk rises sharply, so a clear family record helps the care team weigh inherited risk alongside stroke-related injury. According to the CDC, families should record those relatives and conditions using the family health history guide.

Which relatives count most
Having a parent, brother or sister with Alzheimer's raises personal risk. Risk rises further when more than one first-degree relative is affected, according to the Alzheimer's Association's causes and risk factors page. Include half-siblings, children and second-degree relatives too.
Note the type of dementia when known, age at first symptoms, age at diagnosis and current age or age at death. Family history is important but not decisive. Many people with affected relatives never develop Alzheimer's, and many patients have no family history.
How do you build a pedigree you can share
Start with one page per side of the family. Ask relatives directly when possible, and check death certificates, medical records or obituaries for missing details.
Keep wording exact. Write "Alzheimer's disease diagnosed at 74" rather than "memory loss." Clear labels help clinicians separate Alzheimer's from vascular cognitive impairment after stroke.
- List each relative, relationship, living or deceased status and any Alzheimer's, dementia, stroke, high blood pressure, diabetes or high cholesterol.
- Add age symptoms began, diagnosis and cause of death when known.
- Enter the information in My Family Health Portrait and save or print the pedigree.
- Bring it to primary care, neurology and stroke follow-up, and update it when diagnoses change.
What does family history mean after a stroke
Stroke itself is a major dementia contributor. More than half of survivors have memory and thinking problems within a year and up to one-third develop dementia within five years, as reported in the American Heart Association scientific statement. That statement also places cognitive screening in multidisciplinary post-stroke care with neurology, nursing, therapy, neuropsychology and primary care.
A family history of Alzheimer's adds concern, but it does not mean dementia is certain. Tell the team about new confusion, slower thinking, trouble planning, getting lost or personality change. Early detection lets clinicians check medications, sleep, mood, hearing, vision and vascular risks before decline advances.
Should you seek APOE or other gene tests
The APOE e4 variant raises Alzheimer's risk, with two copies raising it further. Yet many carriers never develop disease and many patients lack e4, so testing cannot predict who will develop it, according to the National Institute on Aging genetics fact sheet. Genetic tests are not routinely used to diagnose or predict Alzheimer's.
Testing for APP, PSEN1 or PSEN2 may arise only with early-onset disease and a strong family pattern, ordered by a neurologist. Seek genetic counseling before APOE testing. Discuss how results would or would not change care, insurance concerns, anxiety and plans for sharing results with relatives.
How does the history shape the prevention plan
Use the pedigree to make screening and vascular control more active. Ask whether family history plus stroke warrants earlier or more frequent cognitive checks, tighter blood-pressure review and diabetes and cholesterol follow-up. The core post-stroke plan stays practical: control blood pressure, cholesterol and diabetes, exercise regularly, eat a healthy diet, maintain healthy weight, limit alcohol and avoid smoking.
Physical activity and blood-pressure control can lower overall dementia risk even when a close relative had Alzheimer's. Bring the updated pedigree to each visit. Circle relatives with new diagnoses since the last appointment so the team can adjust the plan.
