As final result, we found highest tau levels in patients with large stroke areas and subacute stage (media total infarction and multiple strokes, n = 3, arithmetic mean 986 pg/ml), followed by those patients with similar location but in acute stage (n = 4, arithmetic mean 510 pg/ml), followed by those with only limited infarction size (n = 2, arithmetic mean 132.5 pg/ml). Here, MAPT is linked to stroke disorder.
