BACKGROUND Several studies have investigated the interaction between motivation and cognition in both young and older adults, but with inconsistent results. A recent hypothesis suggests exploring the role of dopamine to study this interaction. AIMS To explore how different motivational states can modulate cognitive control, as well as investigate the(More)
Recent researches reported behavioral and emotional impairment in Parkinson's disease (PD), even in the earliest stages. This impairment affects also decision-making and learning processes. The Iowa gambling task (IGT) is commonly used to examine the decision-making capacity. The purpose of the present study was to investigate the neural correlates of(More)
Previous reports documented abnormalities in cognitive functions and decision-making (DM) in patients with chronic pain, but these changes are not consistent across studies. Reasons for these discordant findings might include the presence of confounders, variability in chronic pain conditions, and the use of different cognitive tests. The present study was(More)
BACKGROUND/AIMS This study explores the effective outcomes of a structured cognitive stimulation treatment to improve cognition and behavioral symptoms in people with dementia (PWDs), using a randomized controlled clinical trial. METHODS THIRTY PWDS WERE DIVIDED INTO THREE GROUPS: experimental (treated with cognitive stimulation), placebo (treated with(More)
Recent studies have described brain involvement, mainly at frontal level, in patients with spinal and bulbar muscular atrophy (SBMA), a rare adult-onset motor neuron disease caused by a CAG repeat in the androgen receptor (AR) gene. The aim of our research was to investigate the poorly characterized neuropsychological and psychological profile of these(More)
Focusing on relevant information while suppressing the irrelevant one are critical abilities for different cognitive processes. However, their functioning has been scarcely investigated in the working memory (WM) domain, in both healthy and pathological conditions. The present research aimed to study these abilities in aging and Parkinson's disease (PD),(More)
Several pieces of evidence have highlighted the presence of an age-related decline in risky decision-making (DM), but the reason of this decline is still unclear. The aim of the present study was to investigate the neural correlates of feedback processing in risky DM. Twenty-one younger (age <50 years) and 15 older (age >50 years) adults were tested with(More)
A case of involuntary plantar flexion of the toes and sole with no other neurological pathological sign is reported. The electromyographic activity of some muscles of the involved limb. the behavior of the phenomenon during the sleep-wakefulness cycle and spinal reflex excitability have been studied. According to the clinical and neurophysiological(More)
