Note that POTS/dysautonomia due to poor brain perfusion (not enough blood flow in the brain) is extremely frequent in Ehlers-Danlos Syndrome and is treated and self-treated by very high salt intake (sodium) - and that those with Ehlers-Danlos Syndrome appear to have ten times the rate of MS than the general population. This leads to the obvious suggestion that excess sodium in the brain may be a proxy for poor brain perfusion, which of course profoundly affects cognition! If you want to increase brain perfusion, for whatever reason, mixing concentrace (sea salt with the sodium removed) and potassium chloride are better choices or should also be taken along with sodium chloride.
