The investigator will investigate how light delivering 40 hertz (Hz) affects subjective sleep and cognition in a controlled laboratory study. A lab study will allow the collection of electroencephalogram (EEG) data, perform cognitive tests, and observe the response in t...

This study compares different music therapy (MT) experiences and their impact on memory and language in patients with Alzheimer's disease and Mild Cognitive Impairment. The 12-month study will assess the role of common experiences involving familiar music and other plea...

The primary purpose of this study is to determine whether treatment with lecanemab is superior to placebo on change from baseline of the Preclinical Alzheimer Cognitive Composite 5 (PACC5) at 216 weeks of treatment (A45 Trial) and to determine whether treatment with...

Growing evidence suggests that Alzheimer's disease (AD) pathological changes begin decades before clinical symptoms and tau abnormalities in the locus coeruleus (LC) can be observed since midlife. We have previously demonstrated functional vulnerability of the LC to...

To investigate the impact of a long-term light treatment intervention on sleep physiology and memory in mild cognitively impaired and mild Alzheimer's disease patients living at home. The goal is also to measure the impact of the lighting intervention on caregivers' sle...

To test the long term effect of a light treatment on cognition, sleep and metabolism in patients with Mild cognitive impairment (MCI) or mild Alzheimer's disease or related dementia (ADRD).

This study's main hypothesis is that a delivering a tailored lighting intervention (TLI) will provide a successful means for promoting circadian entrainment and treating metabolic disease and inflammation in patients with mild cognitive impairment (MCI) and Alzheime...

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been ...

The purpose of this study is to evaluate whether treatment with JNJ-54861911 slows cognitive decline compared with placebo treatment, as measured by a composite cognitive measure, the Preclinical Alzheimer Cognitive Composite (PACC), in amyloid-positive participants w...
