Multiple sclerosis (MS) is an inflammatory demyelinating central nervous system (CNS) disease with an uncertain etiology. MS is heterogeneous, involving multiple clinical pathologies, including neurodegeneration, depression, fatigue and sleep disorders, migraine, osteoporosis and cerebral hemodynamic impairments. The underlying causes of these pathologies remain mostly unknown. Based on the accumulating evidence derived from our studies and those of other investigators, we propose that the dysregulation in the neurovisceral integration of cardiovascular modulation can lead to many MS-related clinical symptoms. We show that MS inflammatory and neurodegenerative processes are intertwined with the aforementioned clinical morbidities and are collectively the manifestations of cardiovascular autonomic nervous system (ANS) dysfunction. The strategies for improving sympathovagal balance would likely prevent and minimize many MS-related clinical symptoms, improving patients’ quality of life. Similar strategies could be applied to other autoimmune and neurodegenerative diseases where autonomic imbalance plays a role.
