Alzheimer's & Dementia Family Pattern

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.

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.

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.

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.
