The new definition and diagnostic criteria of Parkinson's disease

[...]to account for the long prodromal stage of Parkinson's disease and to set the stage for earlier intervention in the future, the first ever Movement Disorder Society research criteria for prodromal Parkinson's disease were proposed.3 The criteria's approach is unique because it uses statistical methods (the Bayesian naive classifier) to estimate the likelihood that a patient has prodromal Parkinson's disease. [...]the field of prodromal Parkinson's disease is still in its relative infancy; the method provides a scaffold upon which results of new diagnostic tests for prodromal Parkinson's disease can be continually added. Because the field of Parkinson's disease is constantly evolving, diagnostic methods need to be constantly updated.\n PC received grant support from the Ministry of Science and Technology of China.
