Up-to-date List of Dystonia Medical Research Studies

What Research is Being Done?

A clinical study involves research using human volunteers (also called participants) that is intended to add to medical knowledge. There are two main types of clinical studies: clinical trials (also called interventional studies) and observational studies. Following list includes both interventional and observational studies.

These studies may lead to new treatments and are adding insight into Dystonia etiology and treatment.

A major focus of Dystonia research is the development of new drugs and other treatment options. Studies seek to identify new drugs to treat various related disorders and to find safer, more effective doses for medications already being used. Other research is aimed at identifying receptors or drug targets.
