ABSTRACT
With the increasing availability of predictive genetic testing for adult-onset neurodegenerative conditions, it is imperative that we better understand the impact of learning one's risk status. Frontotemporal degeneration (FTD) is the second most prevalent cause of early-onset dementia. About one-third of patients have an identifiable genetic etiology, and some genetic variants that cause FTD can also cause amyotrophic lateral sclerosis (ALS). To understand individuals' risk perception and broader experience of living at risk, we completed semi-structured telephone interviews with 14 asymptomatic adults who tested positive for a variant known to cause risk for FTD and/or ALS. We conducted a thematic analysis, and within the core topic of identity, we derived three themes conceptualization of FTD and ALS as a threat to identity, enduring uncertainty and dread, and varying centrality of risk status to identity. FTD and ALS risk raised fundamental issues for participants related to the essence of personhood, challenged them to confront Cartesian dualism (the philosophy of mind-body separation), and exposed how time, relationships, and social roles have affected their understanding of the nature of the self. Our findings provide important insight into how being at genetic risk shapes an individual's identity. We conclude that genetic counseling interventions that allow for identity exploration, anticipatory guidance, and uncertainty management should be utilized when supporting persons at risk.
