Dementia can ultimately be understood as a linguistic, neurogenic, and cognitive disorder. With the increasing average life expectancy, the number of individuals affected by dementia continues to rise, underscoring the importance of early and accurate diagnosis. A detailed assessment of not only language processes can provide valuable information to both healthcare professionals and family members, particularly in developing an appropriate therapeutic plan. Results of the verbal fluency test reflect not only the overall level of language abilities, but also the functional integrity of executive functions and semantic memory. Due to its simplicity and time efficiency, the verbal fluency test appears to be a suitable tool for the differential diagnosis of dementia, mild cognitive impairment, and normal ageing. This review article summarizes current findings on its clinical utility, with particular attention given to clustering and switching strategies.
