How Alzheimer's Disease studies are organized in the registry

The registry typically spells this condition “Alzheimer disease” (without the apostrophe-s), and both spellings appear across listings. Early-stage research uses its own vocabulary — prevention and early-intervention studies are often filed under “mild cognitive impairment,” “prodromal,” or “preclinical” rather than the disease name, and some enroll cognitively healthy volunteers at elevated risk. This directory also has a dedicated mild cognitive impairment page.

Terms that often appear in related listings

These describe how studies tend to be titled and grouped on ClinicalTrials.gov — they are search vocabulary, not medical guidance.
