ECOG visuospatial subscale

1. ECOG visuospatial subscale has no effect on cognitive function in humans.

   “ECOG visuospatial scores across the whole CU group were unrelated to MMSE or objective visuospatial cognition.”

1. ECOG visuospatial subscale is associated with tau PET in humans.

   “Subjective visuospatial concerns were associated with right‐hemisphere predominant tau in temporoparietal and prefrontal cortices”

1. Amyloid PET is associated with ECOG visuospatial subscale in humans (t = 3.4, p = 0.001).

   “ECOG visuospatial scores were higher in PiB+ individuals compared to PiB‐ individuals ( t = 3.4, p = 0.001).”
