Verbal fluency in Huntington's disease: a longitudinal analysis of phonemic and semantic clustering and switching.
Two underlying components of verbal fluency tasks have been identified as clustering (the ability to generate successive words within a sub-category) and switching (the ability to shift from one sub-category to another). Selective impairment of switching ability occurs in patients with frontostriatal pathology, whilst clustering ability is compromised with temporal lobe dysfunction. Letter flue...

متن کاملPhonemic verbal fluency and age: A preliminary study
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...
متن کاملNon-Verbal and Verbal Fluency in Prodromal Huntington's Disease.
BACKGROUND This study examines non-verbal (design) and verbal (phonemic and semantic) fluency in prodromal Huntington's disease (HD). An accumulating body of research indicates subtle deficits in cognitive functioning among prodromal mutation carriers for HD. METHODS Performance was compared between 32 mutation carriers and 38 non-carriers in order to examine the magnitude of impairment acros...
