Official title

Healthy Control Population für PAIS-ME/CFS: Studie Zur Evaluation möglicher Biomarker Und Untersuchungsmethoden für Die PAIS-ME/CFS-Diagnostik Bei Gesunden Probanden

Overview

Using the data from the HelP study, the underlying processes of the diseases ME/CFS and PAIS are to be researched and elucidated. The comparison of affected patients with healthy controls is intended to identify disease-specific patterns that could be related to the development or progression of the disease. The aim is to find a suitable biomarker for diagnostics and to develop therapeutic approaches.

Detailed description

The underlying pathomechanisms of the diseases PAIS and ME/CFS are to be investigated and elucidated in more detail. The aim is to establish a cohort of healthy controls at our MRI Chronic Fatigue Center (MCFC). Within this cohort, the measurement instruments used so far in ME/CFS diagnostics will be validated. In addition, data material from this pool should be used for the statistical evaluations of various case-control studies of our center and our cooperation partners in order to find and develop a suitable biomarker for diagnostics and therapeutic approaches for PAIS and ME/CFS.
