Results: Patients with AD copied the figure in a more fragmented way with a longer pause than NCs (EOAD: P=.045 LOAD: P=.01). The stroke patterns and kinetics of normal controls (NCs) and patients with early-onset AD (EOAD) and late-onset AD (LOAD) were analyzed by comparing the pen tip trajectory, spatial arrangement, and similarity of the finished drawings. Methods: A digital pen and tablet were used to copy complex figures. Objective: This study aims to establish a scoring system that addresses not only the spatial arrangement of the finished drawing but also the drawing process of patients with AD by using digital pen data. However, the conventional scoring system based on pen and paper has a limited ability to reflect these detailed behaviors. Patients with AD have an increased tendency for exhibiting extraordinary behaviors in the RCFT for selecting the drawing area, organizing the figure, and deciding the order of images, among other activities.
