Brain-computer interface (BCI) technology enables people to use direct measures of brain activity for communication and control. The National Center for Adaptive Neurotechnologies (NCAN) and Helen Hayes Hospital are studying long-term independent home use of P300-based BCIs by people with amyotrophic lateral sclerosis (ALS). This BCI use takes place without technical oversight, and users can encounter substantial variation in their day-to-day BCI performance. The purpose of this study is to identify and evaluate features in the electroencephalogram (EEG) that correlate with successful BCI performance during home use with the goal of improving BCI for people with neuromuscular disorders.

To assess the efficacy of tirasemtiv, a fast skeletal muscle troponin activator, vs. placebo in patients with amyotrophic lateral sclerosis.
In this study, we examined the potential causal effect of smoking on amyotrophic lateral sclerosis using the Project MinE data involving 12,577 patients with amyotrophic lateral sclerosis and 23,475 c...
Susceptibility-weighted imaging (SWI) has been used to identify neurodegeneration in amyotrophic lateral sclerosis (ALS) through qualitative gross visual comparison of signal intensity. The aim of thi...
Upper and lower motor neuron signs are required for the diagnosis of amyotrophic lateral sclerosis. The detection of upper motor neuron signs is key for the diagnosis, as quite a few patients with amy...
Statins are commonly prescribed drugs that have been inconsistently associated with amyotrophic lateral sclerosis (ALS) risk. We examined associations between ALS risk and overall statin use, statin c...
The goal of this study is to investigate the safety and tolerability of allogeneic Wharton's jelly-derived mesenchymal stem cells administration in the individuals with diagnosed amyotroph...
Cognitive impairment is present in about 30-50% of the patients with amyotrophic lateral sclerosis (ALS). Suitable screening tools are available, but none of these are evaluated in a Norwe...
The first objective is to find some biomarkers, or a profile of biomarkers of ALS to help to diagnosis. The second objective is to better understand the pathogenesis of this disease by the...
We aim to recruit unaffected (healthy) people from families with a known genetic mutation in which at least two relatives have been affected with ALS. Our goal is to identify factors, both...
OBJECTIVES: I. Determine specific clinical features, molecular abnormalities, and laboratory-based biological markers of free radical stress that are associated with amyotrophic lateral...
A glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.
A superoxide dismutase (SOD1) that requires copper and zinc ions for its activity to destroy SUPEROXIDE FREE RADICALS within the CYTOPLASM. Mutations in the SOD1 gene are associated with AMYOTROPHIC LATERAL SCLEROSIS-1.
Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation.

A Poly(A) RNA-binding protein that negatively regulates EGFR ENDOCYTOSIS. An increased risk for developing AMYOTROPHIC LATERAL SCLEROSIS 13 is observed in patients who have more than 23 CAG repeats in the ATXN2 gene coding sequence. Larger CAG expansions in the ATXN2 gene occur in SPINOCEREBELLAR ATAXIA 2 patients.
A widely-expressed protein of approximately 400 to 500 amino acids. Its N-terminal region (DENN domain) interacts with RAB GTP-BINDING PROTEINS and may regulate AUTOPHAGY, as well as PROTEIN TRANSPORT to ENDOSOMES. Expansion of the GGGGCC hexanucleotide repeat in the first intron of the C9orf72 gene is associated with FRONTOTEMPORAL DEMENTIA with AMYOTROPHIC LATERAL SCLEROSIS (FTDALS1).
