title: Quality of life in patients with progressive supranuclear palsy: one-year follow-up.
abstract: The aim of this prospective cohort study that included 46 patients with progressive supranuclear palsy (PSP) was to estimate which demographic and clinical factors were the main contributors to the health-related quality of life (HRQoL) and how did the HRQoL change over a follow-up period of 1 year in these patients. The hierarchical regression analyses showed that the final models demonstrated that gender, included clinical variables and psychiatric/neuropsychological scales, accounted for 68% of the variance in the Physical Composite Score and 73% of the variance of the Mental Composite Score of the 36-item Short Form Health Survey (SF-36). Among variables in both final models, only the score of the Apathy Evaluation Scale showed statistically significant negative predictive value (p < 0.05). Changes in the HRQoL scores were assessed in 28 PSP patients who completed 1-year follow-up period after the baseline examination. Statistically significant decline in the HRQoL was detected for the following scales of the SF-36: physical functioning, vitality, social functioning, and role emotional, as well as in both composite scores (Physical Composite Score and Mental Composite Score). The analyses of magnitude of changes in the HRQoL during 1-year follow-up period showed large effect size (≥0.80) for total scores, as well as for the physical functioning, vitality, and social functioning. In conclusion, despite certain limitations, our study provided some new insights into potential predictors of the HRQoL and its longitudinal changes in patients with PSP.
