Increasing CAP scores were associated with coordinated enrichment of eicosapentaenoic (20:5) and docosahexaenoic (22:6) acid\u2010containing phospholipids together with depletion of triglycerides. In contrast, disease onset was characterized by enrichment of triglycerides and of lipids containing palmitate, palmitoleate, and arachidonate, accompanied by an increased palmitoleate\u2010to\u2010palmitate ratio of cholesteryl esters. In early manifest individuals, increasing motor severity was associated with depletion of docosahexaenoic acid\u2010containing phospholipids, an increased phosphatidylserine\u2010to\u2010phosphatidylcholine ratio and reduced circulating acylcarnitines. These findings were supported by composite lipid scores and leave\u2010one\u2010subject\u2010out sensitivity analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      HD is associated with coordinated plasma lipid remodeling across disease stages.
