Objective: to establish a proof-of-concept and ascertain the reliability of an abbreviated 30-second (30s) phonemic fluency measure as a cognitive screening tool in older adults.
Methods: in all, 201 English-speaking individuals with normal cognition (NC; n = 119) or cognitive impairment (CI; mild CI or dementia; n = 82) were administered a standard 60s phonemic fluency task (FAS/CFL) with discrete 30s intervals denoted.
Results: for all letters, 30s trial scores significantly predicted 60s scores for the same letter, R2 = .7-.9, F(1, 200) = 850-915, p < .001. As with 60s total scores, 30s cumulative scores (for all three trials) were significantly different between NC and CI groups (p < .001). Receiver operating characteristic analyses showed that 30s total scores distinguished NC and CI groups as effectively (AUC = .675) as 60s total scores (AUC = .658).
Conclusions: these findings support the utility and reliability of a short-form phonemic fluency paradigm, as 30s performance reliably predicted 60s/trial totals and was equally accurate in distinguishing impaired/non-impaired groups.

Aims: Cognitive functions are reduced in Parkinson's disease (PD) patients after deep brain stimulation (DBS) surgery. However, the underlying mechanisms remain unclear. The current study attempted to elucidate whether DBS alters the functional connectivity (FC) pattern of cognitive networks in PD patients.

Word fluency (WF) tasks that tap verbal and executive function show deteriorating performance by advancing age. To address the scarcely studied age-related brain correlates of WF, we employed whole-brain voxel-based morphometry to examine gray matter (GM) correlates of semantic and phonemic WF in 46 healthy older adults. Lower phonemic WF score was related to smaller anterior medial temporal GM volume as well as smaller GM volume in the putamen bilaterally.

Background: American Indians have the highest mortality and hospitalizations from head injury of all US groups; however, little is known about prevalence, risk, or outcomes in this population.
Methods: The Strong Heart Study recruited American Indians representing 11 tribes and communities across three regions for two sequential examinations in 2010-2019. Participants were asked to self-report prior head injury, loss of consciousness (LOC), cause, sociodemographics, and behaviors (age, sex, education, bilingual, smoking, alcohol use, stroke).
Cognitive control & the anterior cingulate cortex: Necessity & coherence.
Cortex
November 2024
Institute of Neurology, University College London, London, United Kingdom. Electronic address:
Influential theories of complex behaviour invoke the notion of cognitive control modulated by conflict between counterfactual actions. Medial frontal cortex, notably the anterior cingulate cortex, has been variously posited as critical to such conflict detection, resolution, or monitoring, largely based on correlative data from functional imaging. Examining performance on the most widely used "conflict" task-Stroop-in a large cohort of patients with focal brain injury (N = 176), we compare anatomical patterns of lesion-inferred neural substrate dependence to those derived from functional imaging, meta-analytically summarised.

Article Synopsis
- - This study explores the relationship between mild cognitive impairment (MCI), a potential precursor to Alzheimer's disease, and articulatory precision in speech by introducing a new measure called the phoneme log-likelihood ratio (PLLR).
- - Researchers analyzed speech recordings from various groups, including cognitively unimpaired individuals and those with MCI or dementia, and found that MCI and dementia participants displayed reduced speech fluency and pace.
- - The PLLR demonstrated strong effectiveness in distinguishing between cognitively unimpaired participants and those with cognitive decline, highlighting its potential as a sensitive tool for detecting early changes in speech related to cognitive health.
