Effects of 3-Month Melatonin Treatment on Regional Cerebellar Structure and Blood Biomarkers in Alzheimer's Disease Spectrum

Официальное название

Study on Regional Structural Changes in the Cerebellum Associated with Blood Biomarkers, Cognitive Decline, and Physical Performance in Alzheimer's Spectrum Patients Following a 3-Month Melatonin Treatment Using Digital Health Technology

Обзор

The goal of this clinical trial is to explore and verify the preventive effects of melatonin on the progression of Alzheimer's disease. The study aims to analyze the changes in blood biomarkers (phosphorylated tau, glial fibrillary acidic protein, neurofilament chain), various sleep-related subjective report questionnaire scores, physical performance, cognitive function scores and cerebellar volume change after three months of melatonin administration in patients with Alzheimer's-type mild cognitive impairment (MCI) accompanied by insomnia. The main questions it aims to answer are: 1. Does melatonin administration alter the levels of blood biomarkers associated with Alzheimer's disease? 2. What changes occur in sleep-related subjective report questionnaire scores and cognitive function scores following melatonin administration? 3. Does melatonin administration effect on physical performance? 4. Is there any relations between cognitive decline, phsycal performance and cerebellar volume change? We will compare the data collected before and after melatonin administration to determine its preventive effects on Alzheimer's disease progression. Participants Will: 1. Take melatonin every day for 3 months and Complete sleep-related subjective report questionnaires, neuropsychological assessments and physical performance test 2. Visit the clinic at the initial visit and after 3 months for checkups and tests. 3. Complete sleep-related subjective report questionnaires and neuropsychological assessments and physical performance test 4. Provide blood samples for biomarker analysis.
