There has been great progress in Huntington’s disease (HD) research. Yet, effective treatments to halt disease before the onset of disabling symptoms are still unavailable. Scientific breakthroughs require an active and lasting commitment from families. However, they are traditionally less involved and heard in studies. Accordingly, the European Huntington Association (EHA) surveyed individuals at risk (HDRisk) and with premanifest HD (PreHD) to determine which factors affect their willingness to participate in research. Questions assessed research experience and knowledge, information sources, reasons for involvement and noninvolvement, and factors preventing and facilitating participation. The survey included 525 individuals, of which 68.8% never participated in studies and 38.6% reported limited research knowledge. Furthermore, 52% trusted patient organizations to get research information. Reasons for involvement were altruistic and more important than reasons for noninvolvement, which were related to negative emotions. Obstacles included time/financial constraints and invasive procedures, while professional support was seen as a facilitator. PreHD individuals reported less obstacles to research participation than HDRisk individuals. Overall, a high motivation to participate in research was noted, despite limited experience and literacy. This motivation is influenced by subjective and objective factors and, importantly, by HD status. Patient organizations have a key role in fostering motivation through education and support.

Huntington’s disease (HD) is a genetic neurodegenerative disorder, characterised by atrophy of the neostriatum, and cortical grey matter abnormalities. White matter (WM) alterations have recently been identified as a relevant pathophysiological feature of HD, but the etiology of WM degeneration, and its role in disease pathogenesis and progression remain unclear. An increasing body of research suggests that WM changes in HD are due to alterations in myelin-associated biological processes at the cellular and molecular level. This review first discusses evidence from neurochemical studies lending support to the ‘De-myelination hypothesis’ of HD, and pointing towards a role for aberrant myelination and changes in oligodendrocytes in HD WM. Next, evidence from neuroimaging studies is reviewed, the limitations of the described methodologies are discussed and suggested interpretations of findings from published studies are challenged. Although our understanding of HD-associated pathological changes in the brain will increasingly rely on neuroimaging techniques, the shortcomings of these methodologies must not be forgotten. Advances in MRI techniques and tissue modeling will enable a better characterization of the biological properties of WM microstructure, and will allow more specific monitoring of longitudinal changes noninvasively. This, in turn, will provide insight into disease pathogenesis and progression and facilitate the identification of disease-related biomarkers and the specification of outcome measures in clinical trials.
