Purpose: To compare the performance of hearing-impaired and normal-hearing people on phonologic and semantic verbal fluency tests.
Methods: A cross-sectional study was conducted with 48 hearing-impaired adults and 42 individuals (control group) with no hearing or language complaints. Sociodemographic data were collected, as well as the characteristics of hearing loss and of the electronic auditory device (hearing aids or cochlear implant), when relevant. Verbal fluency was tested in two different tasks: by semantic category (animals) and by phonology (letter F).
Results: Educational level has influenced the results of fluency tests in both groups, with more evidence in the hearing-impaired subjects (p<0.001). Hearing-impaired subjects showed worse performance in verbal fluency tests when compared to normal-hearing people in groups with up to 10 years of schooling. In the comparison of performance in the two tests, both groups showed better results in the semantic fluency task.
Conclusion: The hearing-impaired subjects with low educational level evoked fewer words in semantic and phonologic verbal fluency tests in comparison to normal-hearing subjects. Educational level is a relevant issue to the study of verbal fluency in deaf and hearing-impaired people.

Introduction: Studies about dementia in Indigenous communities are still scarce worldwide, especially in low-middle-income countries, limiting timely intervention in minority groups. Our research aimed to bridge this gap by determining the prevalence of dementia and mild cognitive impairment no dementia (CIND), and the associated factors, in a multiethnic Indigenous community in Manaus, Brazil.
Methods: A cross-sectional observational study evaluated the cognitive and functional performances of 141 Indigenous individuals (aged 50 and above).

Introduction: We examined semantic and phonemic fluency in individuals with subjective cognitive decline (SCD) in relation to amyloid status and clinical progression.
Methods: A total of 490 individuals with SCD (62 ± 8 years, 42% female, 28% amyloid-positive, 17% clinical progression) completed annual fluency assessments (mean ± SD follow-up 4.3 ± 2.

Objectives: The extent to which lifestyle shapes trajectories of normal cognitive aging, and the factors with highest potential for mitigating cognitive decline, remain poorly uncharacterized.
Method: Participants of the Rancho Bernardo Study underwent demographic, health, and behavioral characterization at baseline, along with up to seven cognitive assessments over a 27-year follow-up period. Factor analysis of 24 baseline risk variables identified 9 composite factors.
Therapeutic Effects of Theta Burst Stimulation on Cognition Following Brain Injury.

This case report explores the therapeutic potential of theta burst stimulation (TBS) for cognitive enhancement in individuals with brain injuries. The study presents a 38-year-old male suffering from an organic mental disorder attributed to a traumatic brain injury (TBI), who demonstrated notable cognitive improvements following an intensive TBS protocol targeting the left dorsal lateral prefrontal cortex. The treatment led to significant enhancements in impulse control, irritability, and verbal comprehension without adverse effects.

Adults vary in their ability to bring both nonemotion and emotion words to mind (two capacities called and ). However, no studies have examined how emotion fluency emerges across development, despite the fact that mastering emotion language is an important developmental task.
