The aim of this study was to identify determinants of functional disability, patient’s quality of life (QoL) and caregivers’ burden in Huntington’s disease (HD). Eighty HD patients participated in the study. Motor and behavioral disturbances as well as cognitive impairment were assessed using motor, behavioral and cognitive parts of the Unified Huntington Disease Rating Scale (UHDRS); Hamilton Depression Rating Scale was used to assess depression. Disability, health-related QoL and the impact of the disease on the caregivers were assessed using the following methods: UHDRS Functional Assessment Score, SF-36 Scale and Caregiver Burden Inventory. Multiple regression analysis showed that motor disturbances, cognitive impairment, apathy and disease duration were the independent predictors of disability. Depression and cognitive disturbances were the determinants of patient’s QoL, while motor disturbances and depression were the predictors of the caregiver burden. Patient’s disability and QoL as well as caregivers’ burden should be taken into consideration while planning treatment strategy and the results of the present study show that the predictors of those treatment targets are different.

Background: Patients surviving an initial stroke present a significantly increased risk for further strokes. Left atrial appendage closure (LAAC) became an alternative treatment to pharmacological therapy for stroke prevention in atrial fibrillation (AF) patients. Objective: To evaluate the long-term efficacy of LAAC in primary and secondary stroke prevention in patients with AF. Methods: This retrospective study enrolled 139 patients following LAAC who were divided into 2 groups: 37 patients with prior stroke (Stroke Group) and 102 patients without stroke (Control Group). Overall, cumulative follow-up was 530.1 patient-years. Results: Mean CHADS2, CHA2DS2-VASc scores, and HAS-BLED score were higher in patients with prior stroke compared to patients without stroke (3.0 vs. 1.4, p < 0.0001 and 4.6 vs. 2.3, p < 0.0001, 4.0 vs. 2.8, p < 0.0001, respectively). There were no significant differences between other patient factors (sex, heart failure, hypertension, previous stroke/transient ischemic attack, peripheral vascular disease), which may increase the risk of thromboembolism based on the CHA2DS2-VASc score. Average follow-up was 51.3 months in patients with previous stroke and 50 months in patients without previous stroke. Thromboembolic event rate was 0.8 vs. 0.5 (p = 0.72), bleeding event rate was 0 years vs. 1.4 (p = 0.25), and mortality rates were 0.8 vs. 2.1 (p = 0.38) between the Stroke Group and the Control Group. The estimated reductions in thromboembolic and bleeding risks were 89 and 100%, respectively, in Stroke Group, and 91 and 81%, respectively, in Control Group. Conclusion: Patients with prior stroke may be the preferred group for LAAC regardless of the presence or absence of contraindications for anticoagulant therapy.

Intrinsic factors are the most common causes of falls in PD. Every third fall intensifies fear of walking and causes injuries.
