If we check some controls group from the literature, using similar ELISAs, they have lower TNFR1 level in a control population for psychiatric disorders (901 pg/ml) and in a control population for Alzheimer disease (1292 pg/ml), supporting the fact that all SAH patients have higher TNFR1 level than controls and the ones with aneurysm even higher [10,11]. Here, TNFRSF1A is linked to psychiatric disorder.
