Preventing Cognitive Decline With Alternative Therapies
NCT00010920 · View on ClinicalTrials.gov ↗
Study Summary
Preventing dementia is an important goal for our aging population. This proposal is an initial 42 months study of the effect of standardized ginkgo biloba extract (GBE) on preventing or delaying cognitive decline in people age 85 years or older (the oldest old). The study focuses on the oldest old who present a distinct advantage for primary prevention studies because of their particularly high risk for developing mild cognitive impairment (MCI), a precursor to dementia. Because this is a population that has previously been out of the mainstream for use of alternative medicine, the safety of GBE in this age group will also be tested in this study. The study is randomized, placebo controlled and double blind. Approximately 200 elderly cognitively healthy subjects will be enrolled and followed for detection of conversion to MCI. This pilot study is viewed as a necessary first step in order to demonstrate that GBE, an alternative or complementary therapy, has a disease modifying effect on the brain, distinct from a symptomatic effect. The study will test the feasibility of the randomized start design, a trial design proposed as a method for discerning brain- or disease- modifying from symptomatic effects. The magnitude of biological effect of the treatments will also be assessed with volumetric quantitative MRI, a complementary means of confirming whether there is a brain modifying effect (measured as a decrease in brain volume loss with treatment). Peripheral markers of oxidation status will measure possible anti-oxidant effects of GBE.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00010920
The ClinicalTrials.gov registry entry for NCT00010920 describes a study currently listed as completed. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. An enrollment target was not published in the registry record, which is common for early-stage or observational entries. The listed sponsor is National Center for Complementary and Integrative Health (NCCIH), which has 55 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Dementia appearing as the primary indexed condition, and to 1 intervention — of which Ginkgo Biloba Extract is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00010920 reports 1 study location spanning 1 distinct geographic area — top geographies include Oregon. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
