Objective:
This work thoroughly evaluated the association between cognitive status, mental disorders, and semantic verbal fluency (SVF).
Methods:
Correlations between mental disorders, cognitive status, and demographic and medical history of 74 participants were analyzed. The SVF temporal course per 15-second period of a five-category task was assessed.
Results:
Eight SVF principal components, led by a component consisting of the first fifteen-second periods (P1), were extracted. Regression analyses for cognitive status showed that the P1 component was the best predictor.
Conclusion:
Thus, the words articulated during the first fifteen seconds of the SVF task may improve the prognosis and diagnosis of cognitive decline.
