Note: these models can be applied prospectively to new individuals and data sets to generate predictions about clinical status, symptoms and future outcomes. Their levels of diagnosticity, generalizability and ease of application vary, as do the amounts of prospective testing done to date. However, each of these constitutes a research product that can be shared and characterized across laboratories. CBD, corticobasal degeneration; MSA, multiple-system atrophy; PD, Parkinson’s disease; RAVENS, regional analysis of volumes examined in normalized space; SVM, support vector machine.
