Multimodal Imaging Study on Physical Activity in Patients With Alzheimer`s Disease


Brief description of study

This study aims to gain a better understanding of metabolic early changes in neurodegenerative diseases, in order to enable new diagnostic and therapeutic approaches in the future. Further, it aims to identify specific movement-induced changes at the cerebral level, on cognition, on quality of life and physical fitness, and on serology parameters in neurodegenerative diseases.

In general, valid biomarkers are needed for early diagnosis and prediction of disease progression. It has been hypothesized that metabolic changes may precede structural changes and may be examined by intervention with exercise therapy. The non-invasive, in vivo characterization and diagnosis of such metabolic changes is therefore of paramount importance. In this line, this research project is focused on applying magnetic resonance imaging (MRI) based metabolic imaging techniques such as sodium MRI and phosphorus magnetic resonance spectroscopy (MRS) with standard structural and functional MRI methods, combined with exercise training, in order to detect biomarkers early in different stages of neurodegenerative diseases. Moreover, this project aims to examine the sensitivity of metabolic imaging with sodium and phosphorus sequences over classical MRI imaging with whole body fat sequences, in order to detect cerebral alterations.

At the end, the medical benefit of the planned project lies in the fact that the expected findings are groundbreaking for the understanding of the phenomenology and pathobiology of neurodegenerative diseases. This is the basis for the development of new methods for early diagnosis and individualized medicine with the optimization of future treatment options.
