Semantic, phonologic, and verb fluency in Huntington's disease

Semantic, phonologic, and verb fluency in Huntington’s disease

Verbal fluency tasks have been identified as important indicators of executive functioning impairment in patients with frontal lobe dysfunction. Although the usual evaluation of this ability considers phonologic and semantic criteria, there is some evidence that fluency of verbs would be more sensitive in disclosing frontostriatal physiopathology since frontal regions primarily mediate retrieva...

Semantic Fluency in Mild and Moderate Alzheimer’s Disease Seija Pekkala University of Helsinki, FIN Alzheimer’s disease (AD) is characterized by an impairment of the semantic memory responsible for processing meaning-related knowledge. This study was aimed at examining how Finnish-speaking healthy elderly subjects (n = 30) and mildly (n = 20) and moderately (n = 20) demented AD patients utilize...

Phonologic processing deficits in Alzheimer's disease.

We investigated phonologic production in patients with mild to moderate Alzheimer's disease (AD) on a repetition task. AD patients produced significantly more speech errors than age-matched controls. AD patients' errors, unlike those of controls, resulted in the transformation of real words into pseudowords, occurred disproportionately in word-initial positions, and were not influenced by the p...
