Wolfram Research @ WUFunded by NIH, ADA, JDRF, Snow Foundation6Human ResearchWhy do longitudinal patient studies?Clinical trials require:Knowledge of natural history of diseaseMethods for capturing overall disease severity (rating scale)Reliable and sensitive markers of change in disease statusIdentification of the most important clinical targets of treatment

This information did not exist prior to our studyWe have made significant progress on addressing these questions, but need more longitudinal data to improve our understanding.

Human Research ProgressWe have:Defined specific brain structural differencesDetermined that balance & gait differences are apparentDeveloped, and shown reliability and validity of the Wolfram Unified Rating Scale (WURS)Described auditory and vestibular findingsDescribed overall clinical phenotype

ConclusionsDirect, quantified measurement of Wolfram features reveal subtle brain structure and functional differences at an early stage.

Understanding the developmental vs. degenerative course of these features will be important.

All of this information is crucial for preparing for future clinical trials.

Human Research ProgressResearch clinic funded until 2016Next years dates: 7/15/14 7/19/14Possible additional research clinics during the year or overlapping clinics e.g. 7/14-7/16 and 7/16-7/19Add siblings?Possibly move some assessments to the clinical side onlyCollaboration with Dr. Barrett in UKBlending registriesHarmonizing data collection, disseminate WURS
