Cross-cultural adaptation and psychometric properties of the Brazilian Portuguese version of successful aging scale in community-dwelling older adults.

There is a growing consensus regarding the multidimensional nature of successful aging (SA), including both the biomedical and psychosocial domains of the aging process. The Successful Aging Scale (SAS) is a self-rated instrument addressing both of these components. The aim of this study was to analyze the psychometric properties of the Brazilian Portuguese version of the SAS (SAS-B) with regard to reliability and validity in 949 Brazilian community-dwelling older adults (53.

Clinical Utility of Two- and Three-Dimensional Visuoconstructional Tasks in Mild Cognitive Impairment and Early Alzheimer's Disease.

Objective: The aim of this study was to investigate whether different types of visuoconstructional abilities are useful to distinguish individuals with mild cognitive impairment (MCI) and Alzheimer's disease (AD) from healthy controls (HCs).

Method: We selected 20 patients with MCI and 14 with AD diagnosis based on standard criteria. The neuropsychological performance of MCI and AD groups were compared with that of a group of 11 HCs using a standard neuropsychological battery and visuoconstructional tasks that differed difficulty and type of implicated skills (graphomotor vs.

Neurostimulation for cognitive rehabilitation in stroke (NeuroCog): study protocol for a randomized controlled trial.

Background: Stroke patients may present severe cognitive impairments, primarily related to executive functions. Transcranial direct current stimulation has shown promising results, with neuromodulatory and neuroplastic effects. This study is a double-blind, sham-controlled clinical trial aiming to compare the long-term effects of stimulation in two different cognitive regions after a stroke.
