For PC4 (psychosis), largest performance changes over time were noted in LBD pathology patients (Visit 2: t = 2.2; P = 0.02; Visit 3: t = 3.4; P < 0.001), and at the final visit for patients with pathological labels of FTLD TDP-43 (t = 2.8; P = 0.004) and PSP (t = 2.6; P = 0.008). This evidence concerns the gene TARDBP and psychotic disorder.
