Our results show that these digital metrics, measuring visual short‐term memory, long‐term memory, visuospatial copying, executive function, and processing speed, are associated with both GFAP and NfL cross‐sectional levels in a cohort of AD and HC, even if such associations were of lower magnitude compared to p‐tau181 (Figure 4A,B). The gene discussed is GFAP; the disease is Alzheimer disease.
