Abstract:

Subjective memory complaints may be an early marker of degenerative diseases; however, it may also be a normal aging process. Discovering a cognitive-language task that can well detect subtle changes in individuals with Subjective Cognitive Impairment (SCI) is crucial at the preventive medicine level, which emphasizes early detection of groups at high risk of cognitive impairment. Twelve patients with amnestic mild cognitive impairment, 12 with SCI, and 12 age- and educationmatched Normal Elderly (NE) performed concrete word definition tasks. Regardless of word frequency, the mean score for word definition was significantly lower in the order of NE, SCI, and aMCI. A significant difference was found in the prevalence of definition types among the three groups. The prevalence of error types observed during word definition differed between the three groups. In conclusion, a definition task may provide richer information on the semantic-lexical impairment in SCI.
