A three-generation genogram depicting the hereditary pattern of bipolar spectrum disorders across a family system. Features Bipolar I, Bipolar II, undiagnosed mood instability in older generations, and the impact of psychiatric illness on marital and parent-child relationships.
Clinicians typically introduce this type of genogram during an intake assessment to build a three-generation picture of the family before treatment planning begins. The map helps the therapist apply Bowen Family Systems Theory by locating triangles, differentiation levels, and the emotional processes that link presenting symptoms to earlier family patterns. Squares represent male family members, circles represent female family members, horizontal lines connect couples, and vertical lines descend to their children. Dates near symbols mark births, marriages, separations, and deaths, giving the reader a timeline of key family transitions.
Multigenerational transmission patterns become visible when you trace the same relational or behavioral theme across two or more generations. A therapist reading this genogram looks for repetitions in relationship roles, anxiety management strategies, and symptom locations that span grandparents, parents, and the current generation. Identifying those threads allows the clinician to distinguish what belongs to the individual from what was absorbed from the family system, which is often the first step toward lasting change in family or individual therapy.
How conditions and behaviors are passed across generations through family dynamics.
Patterns of enmeshment, cutoff, conflict, and closeness between family members.
How the family operates as a system with roles, boundaries, and recurring patterns.
This 3-generation genogram maps 10 family members with birth years spanning from 1930 to 2000, comprising 6 males and 4 females (2 deceased). The genogram tracks 5 medical/psychological condition categories and 3 emotional relationship types across 4 documented dyads. The index patient is Nathan Brennan (b. 1993), music producer (freelance).
The family system encompasses 3 generations with distinct patterns at each level. The oldest generation includes Agnes, Stanley, Thomas and 1 other, with 2 presenting documented conditions. The middle generation includes Diane, Paul, Victor, with 2 presenting documented conditions. The youngest generation includes Nathan, Sophie, Leo, with 3 presenting documented conditions.
Emotional relationship mapping reveals 2 close relationships, 1 conflictual relationship, 1 distant relationship. Specific patterns include a close relationship between Nathan and Diane, a conflictual relationship between Diane and Paul, a close relationship between Sophie and Paul. Conflictual patterns highlight areas of tension that may benefit from therapeutic intervention and improved communication strategies.
Medical and psychological conditions are documented in 7 of 10 family members (70%). Bipolar appear in 4 members (Agnes, Diane, Victor...), affecting 2 females and 2 males. Mental health conditions appear in 3 members (Agnes, Victor, Nathan), affecting 1 female and 2 males. Depressive disorders appear in 2 members (Diane, Sophie). Comorbidity is observed in 4 family members, with Agnes presenting 2 concurrent condition categories. The multigenerational prevalence of bipolar suggests both genetic predisposition and possible environmental or behavioral transmission pathways.
From a clinical perspective, this genogram offers rich material for therapeutic exploration. The presenting concerns of Nathan Brennan can be contextualized within 3 generations of family patterns. Bowen family systems theory would note the intergenerational transmission of both symptomatic presentations and relational patterns. This case is particularly suited for exploring differentiation of self, family projection processes, and the way anxiety moves through the family emotional system.
A practitioner documenting a family similar to this one would typically record three generations of household composition, significant life events such as births, deaths, marriages, and separations, any relevant medical or mental health history, and the quality of key relationships between members. That information comes from a combination of the client's verbal account, intake questionnaires, and, where available, collateral records. The completed diagram captures both the factual structure of the family and the practitioner's clinical observations about relational patterns, making it a reference that can be shared across disciplines or reviewed at future stages of treatment.
GenogramAI's AI genogram generator allows you to build a diagram like this one from a plain-language description of the family. You type or paste a narrative, such as the basic structure and any key relationships or health history you want to include, and the AI parses that text, places the correct symbols, draws the appropriate relationship lines, and arranges the layout automatically. The result is a fully editable diagram that you can refine, annotate, and export for clinical records or educational use. Try the AI genogram creator to generate your own genogram from a text description in seconds.
