Overview

Observational analysis reveals differences in lexical processing between healthy controls and AD patients, indicating varying impacts by severity.

Key Points

  • Individuals with mild and moderate AD showed significant differences in lexical processing speed and accuracy compared to healthy controls.
  • Mild AD patients displayed a notable advantage in processing high-frequency words, while moderate AD patients only excelled in orthographic accuracy.
  • Participants included 180 older adults divided into three groups: healthy controls, mild AD, and moderate AD, with further subgroup experiments.
  • Results highlighted substantial deterioration of lexical processing in AD, especially among those with moderate disease severity.
