Living with Risk, Aging with Uncertainty: A Narrative Review of Health and Genetic Vulnerability in Huntington's...

Background/Objectives: Huntington's disease (HD) is an autosomal dominant, neurodegenerative disorder that, because of the availability of presymptomatic genetic testing, places at-risk individuals in an anticipatory situation of great emotional, ethical, and social complexity. This review synthesizes the subjective experiences and coping strategies of individuals aware of their genetic risk before clinical diagnosis, emphasizing the importance of patient and family narratives as critical sources of evidence for enhancing care protocols. Methods: This work is a narrative review supported by a systematic literature search. Of the 75 studies analyzed, 22 met the inclusion criteria-i.e., qualitative research, reviews, and case studies addressing emotional, cognitive, behavioral, and ethical coping mechanisms. The information was structured within a thematic matrix, and inductive coding was applied to identify recurring patterns, unresolved tensions, and gaps in the literature. Results: Presymptomatic genetic diagnosis may trigger processes of anticipatory grief, disrupt individual and familial identity, and lead to constant somatic self-monitoring. Coping strategies vary from proactive approaches-e.g., seeking information and building support networks-to narrative reframing that emphasizes acceptance and the resignification of risk. Analyzing these narratives allowed us to identify silenced ethical dilemmas and family rituals that help alleviate uncertainty-dimensions often overlooked by traditional quantitative methods. Moreover, risk awareness also impacts reproductive and care planning decisions, underscoring the importance of ongoing, context-sensitive support. Conclusions: Coping with genetic risk in Huntington's disease extends beyond the biomedical aspects to encompass relational, ethical, and narrative dimensions. Incorporating narrative-based medicine into genetic and psychosocial counseling is crucial for identifying implicit needs and providing more empathetic, individualized care.
