Correlation between motor symptoms, cognitive function, and optical coherence tomography findings in Parkinson's disease.

Purpose: This study aimed to evaluate the total macular thickness as well as the thickness of the inner and outer retinal layers in patients with Parkinson's disease. It also aimed to verify the correlation of these parameters with motor symptoms and cognitive function.

Methods: A total of 46 eyes of 23 patients with Parkinson's disease and 40 eyes of 20 healthy controls were included in the study.

Proposed protocol for post COVID-19 cognitive rehabilitation for attention and memory.

Unlabelled: Since the beginning of the COVID-19 pandemic, many people suffered from Long Covid Syndrome, in which affected individuals do not recover immediately after the end of the infectious and inflammatory process caused by the virus. The most common neuropsychological symptoms of this syndrome are: memory decline, lack of attention, anxiety and depression.

Objective: The purpose of this study was to develop a proposed cognitive rehabilitation protocol for post-COVID individuals with cognitive symptoms.

Remote cognitive rehabilitation of attention: a case series pilot study with post-stroke patients.

Unlabelled: Cognitive deficits are highly prevalent following a stroke, with memory, attention, and psychomotor speed being among the most affected functions. Prior research indicates that cognitive rehabilitation for stroke patients yields substantial improvements in cognitive performance and concurrently exerts a positive influence on reducing depressive symptoms.

Objective: The goal of this study was to provide a description and assessment of the influence of cognitive rehabilitation on the attentional performance and depressive symptoms of individuals diagnosed with stroke.

The effects of reading and watching fiction on the development of social cognition: a systematic review.

Social cognition is an umbrella term used to address the set of neurocognitive processes involved in effective social interaction, such as Theory of Mind and empathy, and is important for understanding of others' intentions and actions and decision making. Narratives can serve as tools for learning social norms and understanding other people, as they involve mental simulations of social interactions. This review aimed to gather the results of current studies on the effects of reading and watching fiction movies on the development of social cognition.

Dance therapy and cognitive impairment in older people: A review of clinical data.

The growing interest for nonpharmacological treatment alternatives to older people with mild cognitive impairment or dementia has increased exponentially for the past few years; in this context, dance therapy is an effective therapeutic tool in improving the cognition of older people. The aim of this study was to verify whether dance therapy is a viable tool in promoting benefits with regard to the cognition and mood of older people with cognitive impairment. A database search covering the past 10 years was carried out.

Sleep disorders and attention: a systematic review.

Background: Sleep is a special physiological state that occurs cyclically. The probable role of sleep in our organic functions remains to be explored to clarify the impact of sleep on brain functions. Sleep deprivation is known to affect all parts of the brain separately and independently, but further research is needed on the impact of sleep disorders on attention, particularly the specific types of attention that are most affected, and whether there is such a correlation.

Optical coherence tomography in neurodegenerative disorders.

Structural imaging of the brain is the most widely used diagnostic tool for investigating neurodegenerative diseases. More advanced structural imaging techniques have been applied to early or prodromic phases, but they are expensive and not widely available. Therefore, it is highly desirable to search for noninvasive, easily accessible, low-cost clinical biomarkers suitable for large-scale population screening, in order to focus on making diagnoses at the earliest stages of the disease.

Remote cognitive rehabilitation in patients post-cerebrovascular accident: an experience report.

Background: Aiming to contribute to the reduction of cognitive impairment, as well as to improve the quality of life of patients affected by stroke, it was proposed to carry out a cognitive rehabilitation focused on attentional aspects (sustained, alternate, selective and divided attention). Due to the new Coronavirus pandemic and the need for social isolation, the rehabilitation was adapted to the remote model.

Methods: The rehabilitation was designed and carried out with six patients, coming from a public neurology outpatient service, who had suffered a stroke within a period of up to one year before the start of rehabilitation.

Open Practical Laboratories in the Neurosciences: An outreach program for neuroscience communication in middle schools.

The Open Practical Laboratory in the Neurosciences is an outreach program that seeks to improve the knowledge of the neurosciences by elementary school students and to promote better attitudes in relation to neuroscience, science in general, and scientists. It consists in practical and demonstration activities on the theme of the neurosciences. This outreach strategy was applied in four public schools in a municipality in Southeastern Pará, Brazil characterized by low performance in educational reviews in Brazil.

An interdisciplinary approach aiding the diagnosis of primary progressive aphasia: A case report.

Frontotemporal dementia (FTD) is one of the most common causes of early-onset dementia with primary progressive aphasia (PPA) being the second-most-frequent form of this degenerative disease. Despite the similarity with progressive dementia (especially in early stages of Alzheimer´s disease), three types of PPA can be differentiated: semantic, agrammatic and logopenic (subtype discussed in this study). To date, no medications have been shown to improve or stabilize cognitive deficits in patients with PPA.

Functional magnetic resonance imaging response as an early biomarker of cognitive decline in elderly patients with metabolic syndrome.

Objectives: We assessed whether potential changes in brain activation patterns of elderly individuals with metabolic syndrome (MetS) who were cognitively healthy (without mild cognitive impairment or dementia) were associated with cognitive decline in executive function in the short-term.

Method: We analyzed 43 individuals (23 MetS, 20 controls) using a global geriatric evaluation, a neuropsychological battery, and task-related (attention) fMRI exam. Correlation analysis between the fMRI signal at baseline and cognitive impairment after 1year was based on the voxel-based Pearson coefficient, corrected for multiple comparisons.

Cognitive assessment in an elderly population with metabolic syndrome in Brazil.

Unlabelled: Chronic degenerative conditions are very common in the elderly. According to medical literature, there is a correlation between cognitive impairment among elders and arterial hypertension/hyperglycemia which in turn are common diseases among the elderly population worldwide. Nonetheless, data on the association between cognitive impairment and Metabolic Syndrome (MetS) remains controversial.
