Abstrakt:	Verbal fluency (VF) has been one of the most frequently used instruments in clinics and research, both independently or included in a battery recommended for the detection of cognitive alterations. Phonemic-verbal fluency (PVF) is an interesting variant for cognitive diagnosis particularly because studies indicate that it is less influenced by age. Objectives: 1. To estimate the effects of age on PVF tests in their original forms, with the /f/-/a/-/s/ phonemes. 2. To estimate the effects of the phoneme /p/ and compare it to the original form in item generation. 3. To verify associations between the Token Test (TT), Mini-Mental State Exam (MMSE) and depressive symptoms on performance with /f/-/a/-/s/-/p/ phonemes. Methods: Forty-eight healthy individuals with ages ranging from 30 to 80 years were evaluated with the MMSE, TT and PVF tests. Results: Age was correlated with the MMSE, TT and depressive symptoms. There was no association between age and performance on the fluency test, independent of the phoneme used. Among the socio-demographic factors studied, age had a significant impact on performance. There was no phoneme effect in item-generation, when comparing the traditional form of VF (/f/-/a/-/s/) and the /p/ phoneme. Conclusions: The traditional form of FAS is interchangeable with the modified presentation, therefore both forms may be used in clinical or research settings. PVF is a valuable approach for detecting cognitive alterations in the aged, given its stability throughout the ageing process.
