Dementia Clinical Trials in Portland, OR

PREVENTABLE is a multi-center, randomized, parallel group, placebo-controlled superiority study. Participants will be randomized 1:1 to atorvastatin 40 mg or placebo. This large study conducted in community-dwelling older adults without cardiovascular disease (CVD) or dementia will demonstrate the benefit of statins for reducing the primary composite of death, dementia, and persistent disability and secondary composites including mild cognitive impairment (MCI) and cardiovascular events.

The purpose of the Clinical Procedures To Support Research (CAPTURE) study is to utilize information collected in the medical record to learn more about a disease called amyotrophic lateral sclerosis (ALS) and related disorders. Read Less

Malnutrition significantly contributes to the disability and mortality associated with Alzheimer's disease and Alzheimer's disease-related dementias. Thus, nutritional status is one important, modifiable clinical factor for maintaining physical and cognitive health among persons with dementia (PWD). This project will pilot an innovative approach to enhancing nutrition through the use of transitional-state snack supplements, or foods that start as one texture and change to another. Specifically, this study aims to demonstrate the feasibility, acceptability, and safety of a transitional-state therapeutic nutrition supplement among adults with dementia. The central hypothesis is that access to ready-made, savory, nutrient- dense snack supplements that resemble "typical" preferred foods and eating habits will result in improved nutritional intake and status among PWD.

This study will enroll participants with idiopathic REM sleep behavior disorder (RBD) and healthy controls for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies. Read Less

This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 530 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).

The primary goals of this study are to use optical coherence tomography (OCT) angiography (blood vessel mapping) to: Detect retinal blood vessel and blood flow changes in participants with dementia. Detect amyloid protein deposits in the retinas of participants with dementia. Read Less

Most experts advocate for early detection of cognitive impairment (CI) so that patients and caregivers can be prepared for making difficult decisions and to improve quality of life, but studies show that screening alone isn't sufficient to change clinician actions related to early detection. Using predictive modelling developed with machine learning methods and sophisticated clinical decision support (CDS) tools, it is possible to identify patients at elevated risk for CI and make it much easier for primary care to engage and support patients and caregivers in meaningful care planning. The goal of this study is to implement and evaluate a low-cost, highly scalable CI-CDS system integrated within the electronic health record that has high potential to improve early CI detection and care and translate massive public and private sector investments in health informatics into tangible health benefits for large numbers of people.

This home-based study is a randomized (1:1) placebo-controlled trial of a single infusion of zoledronic acid-5 mg (ZA) for the prevention of fractures in men and women aged 60 years and older with Parkinson's disease and parkinsonism with at least 2 years of follow-up. A total of 3500 participants will be enrolled and randomized in the United States. Participants, follow-up outcome assessors, and study investigators will be blinded to assigned study treatment. This trial is funded by the National Institute of Aging. Read Less

The purpose of this study is to test a revised psychoeducational intervention to help Care Partners for family members with dementia understand and reduce the distressing behaviors that come with progressive dementia. Tele-STELLA (Support via TEchnology: Living and Learning with Advancing Alzheimer's disease and related dementias) is a multicomponent videoconference-based intervention designed to facilitate effective management of behavioral and psychological symptoms common to the later stages of dementia. In the Tele-STELLA intervention, professionals ("Guides") meet with family members ("Care Partners") who care for persons with dementia. Working together, the Care Partners and Guides identify strategies to address upsetting behaviors. The goal of this intervention is to reduce upsetting behaviors and, thus, Care Partner burden.
