About Clinical Research
Understanding Clinical Research
Quick Facts
- Clinical research studies must be performed before a new medicine or treatment can be approved for use and made available to the public.
- There are common characteristics that people must have to participate in a study, called eligibility criteria. Common criteria include age, current medicines, medical history, and other medical conditions.
- Right now, there are more than 500,000 studies exploring a wide range of conditions around the world.1
- Many conditions affect diverse groups of people, so it is important to have diverse groups of people participating in research. Different people may respond differently to medicines.

Consider participating in an Alzheimer’s disease research study.
