For this month's Q&A, Matthew Dublin speaks with McGill University's John Breitner about a European consortium that aims to develop molecular diagnostics for both Alzheimer's and Parkinson's disease. As part of the program, Breitner is developing standardized ways to describe patient samples as a first step in bringing innovations to the clinic. Breitner says that there are a number of biomarkers than can confirm or deny a presumptive diagnosis, but there is not yet a standard way to run tests based on such markers.
