Brain Function and White Matter Changes in Congenital, Acute and Chronic Spinal Cord Lesions

Brief Summary

Detailed Description

Recently new approaches to spinal cord repair have been successfully established in animal models. Promising therapies for promoting spinal axonal regeneration in man will be available in the near future. Most research in the field is focussed on the lesion itself and the perilesional spinal cord. The recovery of motor and sensory function is,however, not permitted by local processes at the spinal level only. The whole central nervous system (CNS) reacts to such a condition. Therefore the modulation of motor and sensory function in spinal cord lesioned patients should be reflected in characteristic changes of cortical brain activity, which are accessible to new non-invasive functional neuroimaging techniques such as functional magnetic resonance imaging (fMRI). Changes of white matter due to axonal damage can also be measured qualitatively and quantitatively using MR diffusion tensor imaging (DTI). Those measures may provide a basis to better understand the pathophysiology underlying spinal cord lesions in man, including changes in brain function over time (during rehabilitation) or related to specific treatment. However, there are no studies available yet addressing those topics or providing mechanism-based approaches for determining the time interval of application of novel neuroregenerative drugs. By investigation of brain activation and white matter changes in patients with congenital(myelomeningocele (MMC)), acute and chronic spinal cord lesions (ASIA A) first and fundamental work in this field will be conducted in this study.
