Cognitive function in patients with late stage amyotrophic lateral sclerosis.
BACKGROUND Subtle cognitive deficits have been found in a substantial percentage of patients with early stage amyotrophic lateral sclerosis (ALS). Cognitive function in later stages of the disease remain to be investigated because the neuropsychological tests that are usually employed, such as written or verbal fluency tests, cannot be performed by those patients because of motor or speech impa...
متن کاملCovert visuospatial attention orienting in a brain-computer interface for amyotrophic lateral sclerosis patients.
BACKGROUND Brain-computer interfaces (BCIs) allow people to control devices by translating brain signals into commands. BCIs represent a concrete solution with regard to communication and motor control disabilities of patients with amyotrophic lateral sclerosis (ALS). Most of the BCIs rely on visual interfaces in which patients must move their eyes to achieve efficient BCI control. This fact re...
متن کاملEEG correlates of P300-based brain-computer interface (BCI) performance in people with amyotrophic lateral sclerosis.
The purpose of this study was to identify electroencephalography (EEG) features that correlate with P300-based brain-computer interface (P300 BCI) performance in people with amyotrophic lateral sclerosis (ALS). Twenty people with ALS used a P300 BCI spelling application in copy-spelling mode. Three types of EEG features were found to be good predictors of P300 BCI performance: (1) the root-mean...
متن کاملA P300-based brain-computer interface for people with amyotrophic lateral sclerosis.
OBJECTIVE The current study evaluates the efficacy of a P300-based brain-computer interface (BCI) communication device for individuals with advanced ALS. METHODS Participants attended to one cell of a N x N matrix while the N rows and N columns flashed randomly. Each cell of the matrix contained one character. Every flash of an attended character served as a rare event in an oddball sequence ...
متن کاملBrain-computer interface (BCI) evaluation in people with amyotrophic lateral sclerosis.
Brain-computer interfaces (BCIs) might restore communication to people severely disabled by amyotrophic lateral sclerosis (ALS) or other disorders. We sought to: 1) define a protocol for determining whether a person with ALS can use a visual P300-based BCI; 2) determine what proportion of this population can use the BCI; and 3) identify factors affecting BCI performance. Twenty-five individuals...
