The purpose of this study was to investigate the support of attentional and memory processes in controlling a P300-based brain-computer interface (BCI) in people with amyotrophic lateral sclerosis (ALS). Eight people with ALS performed two behavioral tasks: (i) a rapid serial visual presentation (RSVP) task, screening the temporal filtering capacity and the speed of the update of the attentive filter, and (ii) a change detection task, screening the memory capacity and the spatial filtering capacity. The participants were also asked to perform a P300-based BCI spelling task. By using correlation and regression analyses, we found that only the temporal filtering capacity in the RSVP task was a predictor of both the P300-based BCI accuracy and of the amplitude of the P300 elicited performing the BCI task. We concluded that the ability to keep the attentional filter active during the selection of a target influences performance in BCI control.
The complications related to amyotrophic lateral sclerosis (ALS) include pain. A higher risk of depression and a negative effect on quality of life (QoL) might be expected in ALS patients with pain. The aims of this study were to evaluate the prevalence of pain in ALS patients, to compare measures of depression and QoL in patients with and without pain, and to study the influence of depression scores and pain on the QoL of ALS patients with pain. Forty ALS patients were enrolled, and 36 were included in the analysis. Seventy-two percent of patients reported pain. Pain intensity was significantly related to a worsening of QoL (p<.05). This effect was no longer significant after considering depression scores as a covariate. Depression scores significantly decreased QoL (p<.02) and this effect remained significant after considering pain intensity as a covariate (p<.05). Our study suggests that pain is frequent in ALS patients and that depressive symptoms are significantly related to poorer QoL. Clinicians should pay more attention to both pain and depressive symptoms in ALS patients considering their effect on QoL.
Most studies on well-being during the COVID-19 pandemic have focused on the mental health of the general population; far less attention has been given to more specific populations, such as patients with mental illness. Indeed, it is important to examine the psychiatric population, given its vulnerability. The present study aimed at assessing the psychological and emotional impact of isolation on patients in Residential Rehabilitation Communities, compared to healthy controls. A questionnaire was administered cross-sectionally on an online survey platform and both psychiatric patients and healthy controls accessed via a designed link. The results showed significant differences between psychiatric patients and controls on Anxiety, Stress, Worry, and Risk Perception variables. Psychiatric patients scored lower on Stress compared to healthy controls and higher on Anxiety, Perceived Risk of getting infected with COVID-19 and Worry about the emergency situation. The results showed that, during the Italian lockdown, psychiatric patients living in residential communities received unbroken support from peers and mental health professionals, maintained their usual medication treatment, and were informed of COVID-19 consequences. This finding provides insight into the differences between residential and healthy populations and highlights the importance of continuous support for psychiatric patients, especially during stressful situations such as a pandemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
