Despite recent advances in genetics, in most cases of Amyotrophic Lateral Sclerosis (ALS) no etiological factor can be identified. Cerebral Arteriovenous Malformations (AVMs) have been associated with ALS development in a few studies, but the nature of this connection is unclear. We report here 3 additional cases of young adults, who had undergone repeated embolizations for complex AVMs, and who then developed, after many years, ALS symptoms and signs. In two of these cases Vascular Endothelial Growth Factor (VEGF) levels were found to be extremely high, in contrast to previous reports...

The number of bacterial cells living within the human body is approximately equal to, or greater than, the total number of human cells. This dynamic population of microorganisms, termed the human microbiota, resides mainly within the gastrointestinal tract. It is widely accepted that highly diverse and stable microbiota promote overall human health. Colonization of the gut with maladaptive and pathogenic microbiota, a state also known as dysbiosis, is associated with a variety of peripheral diseases ranging from type 2 diabetes mellitus to cardiovascular and inflammatory bowel disease...

Mutations in Cu/Zn-superoxide dismutase (SOD1) gene are linked to 10-20% of familial amyotrophic lateral sclerosis (fALS) cases. The mutations cause misfolding and self-assembly of SOD1 into toxic oligomers and aggregates, resulting in motor neuron degeneration. The molecular mechanisms underlying SOD1 aggregation and toxicity are unclear. Characterization of misfolded SOD1 is particularly challenging due to its metastable nature. Antibodies against misfolded SOD1 are useful tools for this purpose, provided their specificity and selectivity are well characterized...

Objective: To assess the contribution of noncoding repeat expansions in Japanese patients with amyotrophic lateral sclerosis (ALS). Methods: Sporadic ALS in Western countries is frequently associated with noncoding repeat expansions in the C9ORF72 gene. Spinocerebellar ataxia type 8 (SCA8) is another noncoding repeat disease caused by expanded CTA/CTG repeats in the ATXN8OS gene. Although the involvement of upper and lower motor neurons in SCA8 has been reported, a positive association between SCA8 and ALS remains unestablished...

Patients with locked-in syndrome (LIS) are typically unable to move or communicate and can be misdiagnosed as patients with disorders of consciousness (DOC). Behavioral assessment scales are limited in their ability to detect signs of consciousness in this population. Recent research has shown that brain-computer interface (BCI) technology could supplement behavioral scales and allows to establish communication with these severely disabled patients. In this study, we compared the vibro-tactile P300 based BCI performance in two groups of patients with LIS of different etiologies: stroke ( n = 6) and amyotrophic lateral sclerosis (ALS) ( n = 9)...

INTRODUCTION: This study investigated the prognostic significance of the cough peak flow (CPF) decline rate in patients with amyotrophic lateral sclerosis (ALS). METHODS: Thirty-four patients with ALS participated. We examined CPF, forced vital capacity (FVC), body mass index, and the revised ALS Functional Rating Scale (ALSFRS-R), and followed patients to death, tracheostomy or non-invasive ventilator dependency. We analyzed the relationship between the rate of decline of each parameter and survival prognosis...

Amyotrophic lateral sclerosis (ALS) is the most common adult-onset neuromuscular disease for which there is currently no effective treatment. The progression of ALS includes loss of motor neurons controlling the voluntary muscles, with much of this loss occurring at the neuromuscular junction. In an effort to better understand changes at the neuromuscular junction, we utilized the wobbler mouse model of motor neuron loss. We examined biceps and end plate morphologies and monitored selected factors involved in end plate function...

BACKGROUND: Brain computer interface (BCI) technology is a communication and control approach. Up to now many studies have attempted to develop an EEG-based BCI system to improve the quality of life of people with severe disabilities, such as amyotrophic lateral sclerosis (ALS), paralysis, brain stroke and so on. The proposed BCIBSHS could help to provide a new way for supporting life of paralyzed people and elderly people. OBJECTIVE: The goal of this paper is to explore how to set up a cost-effective and safe-to-use online BCIBSHS to recognize multi-commands and control smart devices based on SSVEP...

Valosin-containing protein (VCP) is involved in multiple cellular activities. Mutations in VCP lead to heterogeneous clinical presentations including inclusion body myopathy with Paget's disease of the bone, frontotemporal dementia and amyotrophic lateral sclerosis, even in patients carrying the same mutation. We screened a cohort of 48 patients with familial frontotemporal dementia (FTD) negative for MAPT, GRN, and C9orf72 mutations for other known FTD genes by using whole exome sequencing. In addition, we carried out targeted sequencing of a cohort of 37 patients with frontotemporal lobar degeneration with Transactive response DNA-binding protein 43 (TDP-43) subtype from the Netherlands Brain bank...

β-Methylamino-L-alanine (BMAA) has been identified as the potential cause of the amyotrophic lateral sclerosis/parkinsonism-dementia complex (ALS/PDC) observed in the Chamorro people of Guam. The principal hypothesis for BMAA exposure and intoxication relies on the biomagnification of BMAA in flying fox specimens ingested by the Chamorro people. Although high levels of BMAA were quantitated in flying fox specimens utilizing liquid chromatography-fluorescence (LC-FL), there have not been any confirmatory analyses conducted to date...

Different and selective vulnerability among motor neuron subtypes are a fundamental, but unexplained, feature of amyotrophic lateral sclerosis (ALS): fast-fatigable (FF) motor neurons are the most vulnerable, and fast fatigue-resistant/slow (FR/S) motor neurons are relatively resistant. We identified that osteopontin (OPN) can serve as a marker of FR/S motor neurons, whereas matrix metalloproteinase-9 (MMP9) is expressed by FF motor neurons in mice. In SOD1G93A ALS model mice, as the disease progressed, OPN was secreted and accumulated as granular deposits in the extracellular matrix...

Over the past decades, a multitude of experimental drugs have been shown to delay disease progression in preclinical animal models of amyotrophic lateral sclerosis (ALS) but failed to show efficacy in human clinical trials or are still waiting for approval under Phase I-III trials. Riluzole, a glutamatergic neurotransmission inhibitor, is the only drug approved by the USA Food and Drug Administration for ALS treatment with modest benefits on survival. Recently, an antioxidant drug, edaravone, developed by Mitsubishi Tanabe Pharma was found to be effective in halting ALS progression during early stages...

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease, leading to progressive paralysis, dysarthria, dysphagia, and respiratory disabilities. Therapy is mostly focused on palliative interventions. During the course of the disease, verbal as well as nonverbal communicative abilities become more and more impaired. In this light, communication has been argued to be "the essence of human life" and crucial for patients' quality of life. High-tech augmentative and alternative communication (HT-AAC) technologies such as eyetracking based computer devices and brain-computer-interfaces provide the possibility to maintain caregiver-independent communication and environmental control even in the advanced disease state of ALS...
