Clinical trials are research studies in which people (often patients) help test treatments or approaches to prevention or diagnosis to see whether they are safe and effective.
Clinical trials are one stage of long and thorough health research. Trials are carried out in planned phases allowing researchers to ask and answer questions in a way that provides reliable information in the best interests of participants.
Clinical trials are an important part of the process the NHS goes through in making decisions to improve the prevention, diagnosis or treatment of Dementia.
