Conversational repair in individuals with Alzheimer disease.

Purpose: many of the difficulties that usually arise in colloquial conversation may be repaired as the interaction develops. Conversational repair is a linguistic strategy that indicates evidence of the partners' abilities to promote necessary mutual understanding for effective communication. This study aims to analyze the oral text repairs of 10 older adults with Alzheimer's dementia (AD) and 10 older adults without dementia, as well as to verify whether they are a useful element for language disorders identification in AD.

Adaptation and psychometric data of the Exploration of Natural Metalinguistic Skills in Aphasia Protocol (MetAphAs) - Chilean version.

Purpose: This study aimed to cross culturally adapt the Protocol for the Exploration of Natural Metalinguistic Skills in Aphasia (MetAphAs), contributing to the future application in the aphasic Chilean population.

Method: The sample corresponds to 72 healthy subjects in the region of Valparaíso, between the ages of 50 to 85. The MetAphAs measures natural metalinguistic skills and presents the basic elements on which to base the exploration of the metacognitive dimensions involved in verbal behavior.

Executive functions and functional impairment in Latin seniors suffering from depression.

Unlabelled: Functional impairment (FI) relates to the condition of executive functions (EFs). While EFs become affected by age and educational level (EL). Seniors suffering from depression (SSDs) on the other hand show EF-related deficiencies; however, there is hardly any literature available regarding their relationship with FI in Latin SSDs, who usually have low ELs.

Transcranial direct current stimulation: a study on naming performance in aphasic individuals.

Purpose: Compare the results in naming tasks of after-stroke aphasic individuals divided into active and placebo groups pre- and post-transcranial direct current stimulation.

Methods: A double-blind, randomized, controlled study conducted with 14 individuals. Patients underwent five 20-min sessions with stimulation of 2mA's on consecutive days.

Narrative evaluation strategies as metacognitive task in subjects with schizophrenia.

Purpose: This study aims to explore the differences in the evaluative component of the narrative structure in subjects diagnosed with schizophrenia compared to subjects diagnosed with affective psychosis.

Methods: The present investigation was descriptive, not experimental and it included the analysis of the narration evaluative components of interviews of 25 individuals with psychiatric diagnosis of chronic schizophrenia and 25 of chronic affective psychosis, matched by age, gender and sociodemographic characteristics.

Results: The relationship between diagnosis and type of evaluation showed statistically significant results with a chi square value of 39.

Non-invasive brain stimulation and computational models in post-stroke aphasic patients: single session of transcranial magnetic stimulation and transcranial direct current stimulation. A randomized clinical trial.

Context And Objective: Patients undergoing the same neuromodulation protocol may present different responses. Computational models may help in understanding such differences. The aims of this study were, firstly, to compare the performance of aphasic patients in naming tasks before and after one session of transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS) and sham, and analyze the results between these neuromodulation techniques; and secondly, through computational model on the cortex and surrounding tissues, to assess current flow distribution and responses among patients who received tDCS and presented different levels of results from naming tasks.

Transcranial direct-current stimulation induced in stroke patients with aphasia: a prospective experimental cohort study.

Context And Objective: Previous animal and human studies have shown that transcranial direct current stimulation can induce significant and lasting neuroplasticity and may improve language recovery in patients with aphasia. The objective of the study was to describe a cohort of patients with aphasia after stroke who were treated with transcranial direct current stimulation.

Design And Setting: Prospective cohort study developed in a public university hospital.

Language disorders and brain lesion topography in aphasics after stroke.

Unlabelled: Aphasia is a language disorder associated with focal brain lesions. Although the topographic definition of the language area has been widely accepted, there is not necessarily any direct correlation between the lesion site and the manifested symptoms.

Objective: To analyze aspects of language in aphasics in relation to lesion topography.
