About this genogram
A three-generation genogram examining the familial clustering of Alzheimer's disease and other dementias. The paternal grandmother was diagnosed with late-onset Alzheimer's at 72, and a paternal great-aunt at 65. The father is showing early cognitive signs at 60. The maternal grandfather had vascular dementia. APOE4 allele status and cognitive assessment details are included throughout.
Medical analysis
Overview
This 3-generation genogram maps 11 family members with birth years spanning from 1925 to 1995, comprising 5 males and 6 females (4 deceased). The genogram tracks 2 medical/psychological condition categories. The index patient is Ryan Harrington (b. 1992), physician assistant.
Across 3 generations, the Alzheimer's & Dementia Family Pattern family demonstrates hereditary risk patterns. The founding generation includes George, Evelyn, Mildred, with 4 members presenting health conditions.
Health conditions
Medical and psychological conditions are documented in 6 of 11 family members (55%). Neurological conditions appear in 5 members (Evelyn, Mildred, Albert...), affecting 2 females and 3 males. Cardiovascular conditions appear in 2 members (George, Albert). Comorbidity is observed in 1 family member, with Albert presenting 2 concurrent condition categories. The multigenerational prevalence of neurological conditions suggests both genetic predisposition and possible environmental or behavioral transmission pathways.
Genetic counseling perspective
From a genetic counseling perspective, this genogram provides critical risk stratification data. The clustering of cardiovascular conditions and neurological conditions across generations indicates heritable risk factors. Healthcare providers can use this multigenerational map to guide screening recommendations, inform preventive strategies, and counsel family members about their individualized risk profiles.
How do you read the Alzheimer's & Dementia Family Pattern genogram?
- 1
Find each person and generation
Squares are males and circles are females, and each row is one generation, oldest at the top. This one has 5 males and 6 females across 3 generations. - 2
Check the status markers
Markers on a symbol add facts about that person: Deceased (X) and Index Patient (Arrow). 4 people are marked deceased. The index person, the focus of the assessment, is Ryan Harrington. - 3
Follow the family lines
Horizontal lines join partners and vertical lines drop to their children, born left to right in birth order. This genogram uses Marriage and Parent-Child lines. - 4
Read the shading
Shaded symbols mark health conditions: Cardiovascular Conditions and Neurological Conditions. Trace each line of descent to see where a condition recurs and where it stops.
Genogram symbols used in this example
| Symbol | Type | What it means |
|---|---|---|
| Male (Square) | Person Symbols | A square represents a male family member in standard genogram notation. |
| Female (Circle) | Person Symbols | A circle represents a female family member in standard genogram notation. |
| Deceased (X) | Status Markers | An X drawn through the symbol indicates the person is deceased. |
| Index Patient (Arrow) | Status Markers | An arrow pointing to a person identifies them as the index patient — the individual who is the focus of the clinical assessment. |
| Marriage | Structural Relationships | A solid horizontal line connecting two individuals represents a marriage or committed partnership. |
| Parent-Child | Structural Relationships | A vertical line descending from a couple line to a child symbol represents a parent-child relationship. |
| Cardiovascular Conditions | Medical Conditions | Shading indicates heart disease, hypertension, stroke, or other cardiovascular conditions. |
| Neurological Conditions | Medical Conditions | Shading indicates neurological disorders (Alzheimer's, Parkinson's, epilepsy, etc.). |

Frequently asked questions
What clinical patterns does the Alzheimer's & Dementia Family Pattern genogram reveal?
The Alzheimer's & Dementia Family Pattern genogram maps multigenerational transmission of psychological patterns, emotional dynamics, and relationship structures. Clinicians use it to identify recurring cycles of behavior, attachment styles, and communication patterns that may inform diagnosis and treatment planning in family therapy.
Why is the Alzheimer's & Dementia Family Pattern genogram important for medical professionals?
The Alzheimer's & Dementia Family Pattern genogram helps medical professionals identify hereditary risk factors by mapping conditions across generations. It supports genetic counseling, preventive care planning, and helps patients understand their family health history for informed decision-making.
What genogram symbols are used in the Alzheimer's & Dementia Family Pattern example?
This genogram uses Male (Square), Female (Circle), Deceased (X), Index Patient (Arrow), Marriage, Parent-Child, Cardiovascular Conditions and Neurological Conditions. All of them follow standard genogram notation, so the chart reads the same way in any genogram program or textbook.
Can I build a genogram like the Alzheimer's & Dementia Family Pattern example?
Yes. Open GenogramAI, choose Create with AI on the dashboard (paid plans) or open a blank genogram and use Ask AI in the editor (any plan), and describe the family in plain words: who is in it, how they are related, key dates and the relationships or health conditions you want to show. The AI draws the symbols and lines, and you can then edit by hand or ask for one change at a time. A family of 11 people like this one takes a short paragraph to describe. The free plan includes 2 genograms and 5 AI credits a month, with PNG export.
