Alzheimer Disease Clinical Trial
— HERITAGEOfficial title:
A Multi-domain Lifestyle Intervention Among Aged Community-residents in Zhejiang, China
A study conducted in Finland discovered that a multidomain intervention, consisting of physical activity, nutritional guidance, cognitive training, social activities, and management of vascular risk factors, effectively decelerated cognitive decline in healthy older adults who were at an increased risk of cognitive decline. The HERITAGE study is a 2-year clustered randomized controlled trial (clustered-RCT) that explores the efficacy of a multidomain intervention among 1200 elderly residents with a higher risk of cognitive decline and dementia in Zhejiang Province, China

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Global Cognition | Globe cognitive performance (composite z-score) measured by comprehensive Neuropsychological Test Battery (NTB) | Up to 2 years | |
Primary | Domain-specific Cognition | NTB domain-specific cognitive performance (composite z-score) for memory, executive function, attention, language, visuomotor speed and visuoconstruction. | Up to 2 years | |
Secondary | Neuroimaging: MRA | Changes in brain blood flow assessed by magnetic resonance angiography(MRA) | Up to 2 years | |
Secondary | Neuroimaging: MRI | Changes in brain structural integrity (gray matter volume loss, white matter microstructure degradation and increase of cerebrovascular markers) assessed by T1-weighted Magnetization Prepared Rapid Gradient Recalled Echo, Fluid Attenuated Inversion Recovery (FLAIR), T2-weighted, and Susceptibility Weighted Imaging sequences | Up to 2 years | |
Secondary | Neuroimaging: fMRI | Changes in brain functional networks assessed by fMRI | Up to 2 years | |
Secondary | Number of participants with Laboratory Values /Blood markers | Blood samples will be collected from all patients in tubes with ethylenediaminetetraacetic acid 0.1%. Changes in Novel and accessible blood markers to monitor AD- and CeVD- associated pathologies. Plasma concentrations of cardiac markers (High-sensitive cardiac troponin T (hs Troponin T), N-terminal pro b-type natriuretic peptide (NT-proBNP) and Growth/differentiation factor 15 (GDF 15)), and peripheral biomarkers of Aß, tau and synaptic pathology, oxidative stress, endothelial/cardiovascular injury and degenerative protein modifications (DPMs) damaged proteins will be measured by laboratory testings. | Up to 2 years | |
Secondary | Incident dementia | Incidence of dementia. Dementia diagnoses will be made by CDR and DSM-IV criteria. | Up to 2 years | |
Secondary | Clinical Dementia Rating-Sum of Boxes (CDR-SB) | The Clinical Dementia Rating-Sum of Boxes (CDR-SB) is scored from 0 to 18. Higher scores reflect worse performance. | Up to 2 years | |

Higher scores reflect better performance. | Up to 2 years | |
Secondary | Cardiovascular morbidity | Physician-diagnosed cardiometabolic health disorders will be identified based on ICD-9 or ICD-10 codes (in any position). Any incident cardiometabolic morbidity, for example, ardiac dysrhythmias, heart failure, peripheral and visceral atherosclerosis, non-alcoholic fatty liver disease, chronic kidney disease, type 2 diabetes, hypercholesterolemia, and hypertension, will be recorded. | Up to 2 years | |
Secondary | Physical Performance: Grip strength | Grip strength will be assessed by a hydraulic hand dynamometer and expressed in absolute units(kilograms) andrelative units(kilograms divided by bodyweight). | Up to 2 years | |
Secondary | Physical Performance: Gaid speed | Walking pace will be assessed by the speed (m/second) of completing a 1.5 meters walk. | Up to 2 years | |
Secondary | Physical Performance: Balance | Balance will be measured by standing on one foot and expressed in absolute units(seconds). | Up to 2 years | |
Secondary | Physical Performance: Endurance | Endurance will be assessed by the 2MW. Participants will be asked to "walk as fast as you can without running" for 2 minutes around a 50-foot course. A greater distance(m) indicates better endurance. | Up to 2 years | |
Secondary | Physical Performance: Lower limb strength | Lower limb strength will be assessed by 30 second sit to stand test and expressed by completion times. | Up to 2 years | |

Secondary | Changes in lipid Profile | Blood samples will be collected from all patients in tubes with ethylenediaminetetraacetic acid 0.1%. Lipid Profile will be expressed by total cholesterol, LDL-cholesterol, HDL-cholesterol or triglycerides in mmol/L. | Up to 2 years | |
Secondary | Changes in Glucose Regulation | Vascular and metabolic risk factors measured by changes in glucose regulation in mmol/L. | Up to 2 years | |
Secondary | Retinal Imaging Markers | Retinal fundus photographs will be taken of each eye with a nonmydriatic digital camera after dilation of pupils with 1% tropicamide eye drops.
