Multimodal Study About Absence of Dp140 in Becker Muscular Dystrophy: Brain-muscle Imaging, Cognition and Muscle Function (MyoBrain-BMD)
Monitoring patients with neuromuscular disorders is crucial but doesn't always allow for a sufficiently specific approach to all aspects of the condition. However, in the event of future treatment, it is essential for clinical and research teams to have as much information as possible about the disease, particularly regarding its physical, physiological, biological, and neurological aspects.
In this context, it was consider as vital to investigate in greater depth the links between the presence of certain dystrophin isoforms in patients and their potential impacts on cognitive, neurological, and muscular function. The results of this study could serve as a reference for future research and improve the understanding and management of this disease.
All of this data will allow for a precise evaluation of the effects of a potential treatment on the progression of the disease.
