Hi Dr Dennis,,, high salt can reduce cerebral blood flow. High salt in the diet can cause Endothelial dysfunction which is an important cause of reduced cerebral blood. In mice it has been shown that high salt increases IL17 from white blood cells and it can cause Endothelial dysfunction by decreasing nitric oxide synthesis.. Thanks
