Aim. To compare quantitative and qualitative aspects of semantic (i.e., animals) and phonological (i.e., F, A, S, M) verbal fluency test (VFT) in Mild Neurocognitive Disorder (mNCD) patients and healthy controls.
Method. The sample was comprised by 70 participants: 35 mNCD patients, with a mean age of 71.5 (± 8) years old and 13.1 (± 3.6) years of formal education; and 35 healthy controls, with a mean age of 72.1 (± 7.1) years old, and 13.2 (± 3.7) years of formal education. A VFT analysis, in terms of hits and errors, clusters’ number and size, and number of switches was performed.
Results. No significant differences among groups were observed in hits and errors. However, statistical differences were found regarding the employed strategies, whereas healthy controls achieved more clusters than the mNCD group in both semantic and phonological VFT. Moreover, the clusters´ size of phonological VFT was larger in healthy controls than mNCD. No differences were found among groups in number of switches.
Conclusions. Qualitative analysis of VFT provide more specific information regarding cognitive processing and may be a useful tool to differentiate the executive functioning of healthy aging and mNCD, in a brief period of time.
