Quality of life in Huntington's disease: a comparative study investigating the impact for those with pre-manifest and early manifest disease, and their partners

J Huntingtons Dis. 2013;2(2):159-75. doi: 10.3233/JHD-130051.

Abstract

Background: Given the multifaceted nature of this inherited neurodegenerative condition, typically affecting adults in mid-life, it is perhaps not surprising that studies indicate poorer Health Related Quality of Life (HrQoL) in those with the gene-expansion and, by association, in their families.

Objective: This study aimed to extend the current literature by exploring specific life domains, including at an earlier disease stage than usually reported in the HRQoL literature, and in a subgroup of gene-negative partners.

Methods: 355 participants from the TRACK-HD cohort (120 Controls, 118 Pre-HD and 117 early-HD) completed standardised self-report measures of HrQoL (SF36 and QoLI), underwent clinical assessments of capacity and motor function (UHDRS), semi structured interviews assessing neuropsychiatric symptoms (PBA-s), completed paper and computerized cognitive tasks and assessment of behaviours associated with damage to frontal brain circuits (FrSBe).

Results: Each gene-expanded group scored statistically significantly lower than gene-negative sibling controls on the SF36 General Health subscale; neuropsychiatric symptoms and executive dysfunction were associated with reduced HrQoL. Those with Stage II disease reported statistically significantly lower HrQoL than gene-negative controls across physical, emotional and social life domains. Those partnered with manifest participants reported lower HrQoL in the social domain compared to those partnered with at-risk participants furthest from disease onset; and perseverative symptoms in manifest partners were found to be related to lower HrQoL in their gene-negative partners. HrQoL in gene-negative partners of pre-manifest individuals was associated with pre-manifest individuals' neuropsychiatric and cognitive function.

Conclusions: Understanding the nature and timing of disruption to the HrQoL in people who are pre-manifest and diagnosed with HD, and their gene-negative partners, can inform the development of appropriate strategies and interventions.
