Unified Huntington's Disease Rating Scale (UHDRS) (a.e.g. (2000))
(AAN, 1995)
This is a rating system to quantify the severity of Huntington's
Disease. It is divided into multiple subsections:motor, cognitive, behavioral,
functional. These scores can be calculated by summing the various questions
of each section. Some sections (such as chorea and dystonia) require grading
each extremity, face, bucco-oral-ligual, and trunk separately. Eye movements
require both horizontal and vertical grades.
