Altered cerebrovascular response to acute exercise in patients with Huntington's disease.

ABSTRACT: The objective of this study was to determine whether a single session of exercise was sufficient to induce cerebral adaptations in individuals with Huntington's disease and to explore the time dynamics of any acute cerebrovascular response. In this case-control study, we employed arterial-spin labelling MRI in 19 Huntington's disease gene-positive participants (32-65 years, 13 males) and 19 controls (29-63 years, 10 males) matched for age, gender, body mass index and self-reported activity levels, to measure global and regional perfusion in response to 20 min of moderate-intensity cycling. Cerebral perfusion was measured at baseline and 15, 40 and 60 min after exercise cessation. Relative to baseline, we found that cerebral perfusion increased in patients with Huntington's disease yet was
