Brain–body communication in stroke

Abstract

Stroke is a leading cause of death and disability worldwide with limited therapeutic options available for selected groups of patients. The susceptibility to stroke depends also on systemic parameters, and some stroke risk factors are modifiable, such as atrial fibrillation (AF) or hypertension. When considering new treatment strategies, it is important to remember that the consequences of stroke are not limited to the central nervous system (CNS) injury, but reach beyond the boundaries of the brain. We provide here a brief overview of the mechanisms of how the brain communicates with the body, focusing on the heart, immune system, and gut microbiota (GM).
