Autonomic regulation in muscular dystrophy
نویسندگان
چکیده
Autonomic Nervous System (ANS) function has been assessed in several muscular dystrophies. In the last two decades it has been recognized a significant relationship between ANS and cardiac mortality (Palladino et al., 2008). Cardiovascular ANS is frequently studied by using cardiovascular autonomic reflex tests and spectral analysis of heart rate in time and frequency domain (Ewing and Clarke, 1982; van Ravenswaaij-Arts et al., 1993). Heart rate variability (HRV) analysis, which involves measurement and analysis of heart rate variation, provides a quantitative marker of autonomic activity and has proved to be able to detect and measure modification in sympathetic or vagal activity. Moreover, it can be used to estimate the susceptibility for heart arrhythmias (Heart rate variability, 1996a,b).

Autonomic dysfunction in muscular dystrophy: a theoretical framework for muscle reflex involvement
Muscular dystrophies are a heterogeneous group of genetically inherited disorders whose most prominent clinical feature is progressive degeneration of skeletal muscle. In several forms of the disease, the function of cardiac muscle is likewise affected. The primary defect in this group of diseases is caused by mutations in myocyte proteins important to cellular structure and/or performance. Tha...
متن کاملAutonomic regulation in muscular dystrophy
Muscular dystrophies are a heterogeneous group of genetic muscle diseases characterized by progressive muscle weakness and atrophy. Cardiomyopathy and congestive heart failure or conduction system abnormalities that cause arrhythmias, and sudden cardiac death have been observed in muscular dystrophies. Despite the extensive research and ongoing clinical trials in muscular dystrophy to improve s...

Muscular dystrophy is a progressive disease of muscle weakness, muscle atrophy and cardiac dysfunction. Patients afflicted with muscular dystrophy exhibit autonomic dysfunction along with cognitive impairment, severe depression, sadness, and anxiety. Although the psychological aspects of cardiovascular disorders and stress disorders are well known, the physiological mechanism underlying this re...

This is a study on autonomic neuroscience. In a previous paper in [1], we studied a subject affected from facioscapulohumeral muscular dystrophy before and after Ken Ware treatment (NPT). Using the non linear methodology of the Generalized Mutual Information (GMI) analysis of Sensory Motor Rhythm, we produced detailed results evidencing that the mentioned NPT treatment involved a net improvemen...

Background: The association of limb-girdle muscular dystrophy (LGMD) with other neurological disorders is uncommon. Case presentation: We report a 25-year-old female with LGMD who suffered from slowly progressive proximal muscular weakness and atrophy since she was 12 years of age. The patient recently presented with acute loss of left side visual acuity. After evaluation, findings were sugges...
