简要总结
In the study, NextGen SE are on-hand a cohort comprising each 50 pediatric and 50 adult patients, and in which there are an unclear movement disorder or an unclear cognitive disorder, examines the following questions :
Primary:
- Number of diagnoses made by NGS
Secondary:
- restriction of the quality of life by unclear disease
- Cost of not purposeful preliminary diagnostics ( beyond the minimal diagnostic data set )
- Impact of the diagnosis to therapy and follow-up examinations
- Time to diagnosis
