Study on Biomarkers for Early Diagnosis of Alzheimer's Disease

This is an observational study based in China that is tracking elderly people over five years to identify early biological markers of Alzheimer's disease. Researchers are collecting blood, genetic, and brain imaging data across a range of participants — from cognitively normal to diagnosed AD — hoping to build better early-detection tools and a model that predicts five-year risk. No phase is listed because no drug or device is being tested.

China Cognition and Aging Study

This is a large observational study based in China, not a drug or treatment trial. Researchers are building a national database by following thousands of people over time, tracking who develops memory problems or dementia, collecting brain scans, blood samples, and genetic data. The goal is to understand how dementia unfolds in Chinese populations. There is no Phase designation because nothing is being tested for approval — this is research groundwork.

Passive Sensor Identification of Digital Biomarkers to Assess Effects of Orally Administered Nicotinamide Riboside

This trial is testing whether a supplement called nicotinamide riboside (a form of vitamin B3) produces measurable changes in brain energy metabolism in people with mild cognitive impairment or mild Alzheimer's dementia. Researchers are using a passive home sensor device to track digital biomarkers — things like sleep, movement, and breathing patterns — rather than clinic visits alone. The phase is unspecified, so the scale and stage of testing are unclear from the available information.

Predicting Pre-dementia

This observational study is testing whether a multimodal prediction model — combining genetic risk scores, blood biomarkers, health record data, and wearable device readings — can accurately forecast who will progress to early MCI within two years. There is no drug or treatment involved. It is observational, meaning researchers are watching and measuring, not intervening. Think of it as a sophisticated early-warning system study.

Study to Evaluate the Efficacy and Safety of KDS2010 in Patients With Alzheimer's Disease With Mild Cognitive Impairment and Mild Dementia Due to Alzheimer's Disease

This trial is testing KDS2010, an experimental oral drug taken once daily, in people who have early Alzheimer's-related memory problems — either mild cognitive impairment or mild dementia confirmed by amyloid PET scan. Researchers are comparing two doses against a placebo to see whether it improves cognition, daily functioning, and biomarkers over 24 weeks. This is a Phase 2a trial, meaning it is an early test of whether the drug works and is safe — not proven or approved.

Sleep Impairment in Subjects at Risk of Developing Alzheimer's Disease

This study is observing whether poor sleep is linked to cognitive decline in people at early risk of Alzheimer's. Participants undergo sleep studies, cognitive testing, and biomarker checks — no experimental drug is involved. It is a non-interventional, observational study, meaning researchers are watching and measuring, not treating. The goal is to understand whether sleep problems predict or accelerate cognitive decline, which could eventually point toward earlier intervention.

Intravenous Infusion of Umbilical Cord Blood as an Adjunctive Treatment for Alzheimer's Disease

This trial is testing whether infusing stem-like cells from donated umbilical cord blood — on top of a standard Alzheimer's drug — is safe and shows early signs of benefit in people with mild to moderate Alzheimer's. It is an Early Phase 1 trial, meaning the primary goal is safety and finding the right dose, not proving the treatment works. Thirty patients are divided into two dose groups and one placebo group, then followed for six months.

Comparison of Two Non-invasive Neuromodulation Techniques as Synergistic Therapy to Cognitive Stimulation in Amnestic Mild Cognitive Impairment (aMCI)

This trial is testing two types of non-invasive brain stimulation — repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) — each paired with structured cognitive exercises, in people with amnestic mild cognitive impairment. Researchers want to see which combination best supports memory and brain function. This is a Phase NA (feasibility or exploratory) trial, meaning it is designed to gather early data, not to prove a treatment works definitively.

The Effects of Social Isolation and Social Interaction on the Risk of Dementia Progression and Brain Function in SCD (Subjective Cognitive Decline, SCD)

This trial is studying how social isolation and social interaction affect the brain and the risk of progressing from subjective cognitive decline to more serious memory problems.

miR-342-5p/AnkG Pathway in Early AD Synaptic Dysfunction

This study is collecting blood samples, and optionally cerebrospinal fluid, from people with early Alzheimer's and healthy controls. Researchers want to know whether a specific molecular pathway (miR-342-5p/AnkG) shows up in body fluids and could serve as an early detection signal. This is not a drug trial — it is a biomarker discovery study, meaning researchers are building scientific groundwork, not testing a treatment.

Observational stroke study, genotype not relevant

The Imperial Comprehensive Cognitive Assessment in Cerebrovascular Disease (IC3)

This study is testing a new digital cognitive assessment tool called IC3, designed specifically for stroke survivors. Researchers want to know whether it can reliably detect memory and thinking problems after stroke, and whether combining it with brain MRI and blood tests reveals useful markers of cognitive recovery. This is an observational study, not a drug trial — no experimental treatment is being given.
