| Verbal Fluency — Neuropsychological measure of language production, lexical retrieval, semantic memory, executive function, and processing speed. Verbal fluency tests typically require generation of as many words as possible within a fixed time using either a semantic category (e.g., animals) or a phonemic/letter cue.
Typical modulation in Alzheimer’s disease: ↓ verbal fluency is common in mild cognitive impairment and Alzheimer’s disease and may reflect impairment in semantic memory, executive function, lexical retrieval, or processing speed. Improvement in verbal fluency scores is generally interpreted as a favorable cognitive outcome.
Typical modulation in cancer: Not a direct cancer-related molecular endpoint, but may be used to assess cognitive effects of cancer, chemotherapy, radiotherapy, or supportive interventions.
