A clinical trial is a research study in human volunteers designed to answer specific health questions. Carefully conducted clinical trials are the fastest and safest way to find treatments that work in people and ways to improve health.
There are different types of clinical trials. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective under controlled environments. Observational trials address health issues in large groups of people or populations in natural settings.
Clinical trials have led to important discoveries about the beneficial effects of drugs and surgical treatments to improve our ability to treat neurologic diseases.
