Leija-Salazar and colleagues discuss current evidence for somatic mutations in neurodegeneration, focusing on sporadic, usually late-onset neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Parkinson disease (PD) and Alzheimer's disease (AD). Somatic mutation, defined as any acquired post-zygotic change in the nuclear genome, has long been linked to chemically induced DNA damage, aging and cancer but little more than a theoretical basis exists to associate comparable phenomena with sporadic neurodegenerative diseases. Whereas specific exogenous mutagenic chemicals, such as the fungal toxin aflatoxin B1, the amine dye benzo(a)-pyrene, and a tobacco-specific N-nitrosamine, are key examples of proven mutagenic carcinogens , only broad exposure categories, such as tobacco smoke, have been linked positively with ALS and AD, and negatively with PD.

Amyotrophic lateral sclerosis (ALS) is a rare and fatal neurodegenerative disorder. Two forms are recognized, familial (FALS) that accounts for 5-10% of ALS cases, and sporadic (SALS) that accounts for the rest. Early diagnosis of ALS is important since it improves their therapeutic efficacy. Read More

Bulbar onset amyotrophic lateral sclerosis (bALS) is a currently incurable neurodegenerative condition characterized by insidious progression of bulbar muscle paresis; namely dyspnea, dysarthria, and dysphagia. The diagnosis of bALS requires exclusion of mimicking pathologies as the diagnosis of bALS may have significant implications on patients' quality of life, future planning, and familial/social dynamics. Herein we present two cases which were misdiagnosed as bALS when in fact a structural lesion of the hypoglossal nerve was causative. Read More

The N-methyl-D-Aspartate glutamate receptors (NMDARs) are pivotal for the functional and morphological plasticity that are required in neuronal networks for efficient brain activities and notably for cognitive-related abilities. Because NMDARs are heterogeneous in subunit composition and associated with multiple functional regulatory sites, their efficacy is under the tonic influence of numerous allosteric modulations, whose dysfunction generally represents the first step generating pathological states. Among the enzymatic candidates, serine racemase (SR) has recently gathered an increasing interest considering that it tightly regulates the production of d-serine, an amino acid now viewed as the main endogenous co-agonist necessary for NMDAR activation.

Accumulating evidence has shown that astrocytes do not just support the function of neurons, but play key roles in maintaining the brain environment in health and disease. Contrary to the traditional understanding of astrocytes as static cells, reactive astrocytes possess more diverse functions and phenotypes than previously predicted. In the present focused review, we summarize the evidence showing that astrocytes are playing profound roles in the disease process of amyotrophic lateral sclerosis. Read More

Mutations in the same gene are sometimes the cause of different clinically diagnosed neurologic disorders; this emphasizes interrelationships between various neurologic diseases. In this light, we screened SLC52A3, which is the cause of Brown-Vialetto-Van Laere syndrome, and C19orf12, which is the cause of neurodegeneration with brain iron accumulation in 60 Iranian amyotrophic lateral sclerosis (ALS) patients without mutations in the 2 most important ALS-causing genes, SOD1 and C9orf72. To the best of our knowledge, neither SLC52A3 nor C19orf12 has been mutation-screened previously in ALS cohorts. Read More

Genetics has led to a new focus regarding approaches to the most prevalent diseases today. Ascertaining the molecular secrets of neurodegenerative diseases will lead to developing drugs that will change natural history, thereby affecting the quality of life and mortality of patients. The sequencing of candidate genes in patients suffering neurodegenerative pathologies is faster, more accurate, and has a lower cost, thereby enabling algorithms to be proposed regarding the risk of neurodegeneration onset in healthy persons including the year of onset and neurodegeneration severity.

Connexin36 (Cx36) forms gap junctions between neurons, which are called electrical synapses, enabling adjacent neurons to communicate directly. The participation of chemical synapses in neurodegeneration in amyotrophic lateral sclerosis (ALS) has long been indicated, but it remains unclear whether electrical synapses are involved in the pathogenesis of ALS. We performed extensive immunopathological analyses using mutant superoxide dismutase 1 (SOD1) transgenic mice and their littermates to investigate whether Cx36-made electrical synapses are affected in motor neuron diseases.

Amyotrophic lateral sclerosis (ALS) is a calamitous neurodegenerative disorder characterized by denervation of upper and lower motor neurons. Numerous hypotheses suggest that toxic protein misfolding and aggregation cause ALS, similar to that of other neurodegenerative diseases, such as Alzheimers and Parkinsons. Protruding causes of familial ALS are mutations in the gene encoding Cu/Zn superoxide dismutase-1 (SOD1), which decrease protein stability and endorse protein aggregation. Read More

Myasthenia gravis (MG), amyotrophic lateral sclerosis and Guillain-Barre syndrome (GBS) have been classically considered as exceptional or unusual diseases in people with a geriatric profile. Over the past 25 years, several population-based studies have been conducted in the Osona area (Barcelona), which, for the first time, has led to describing the high global incidences in the elderly, especially those over 80 years-old. The results suggest the possibility of underdiagnosis of these neuromuscular diseases in the elderly, a fact that could be especially relevant in the case of MG and GBS, since they are 2potentially reversible entities with high mortality in the event of underdiagnosis and absence of treatment.

Amyotrophic lateral sclerosis, the most common neurodegenerative disease affecting motor neurons, lacks an effective treatment. A small fraction of amyotrophic lateral sclerosis cases have a familial origin, related to mutations in causative genes, while the vast majority of amyotrophic lateral sclerosis cases are considered to be sporadic, resulting from the interaction between genes and environmental factors in predisposed individuals. During the past few years, dozens of drugs have been postulated as promising strategies for the disease after showing some beneficial effects in preclinical cellular and murine models. Read More

Neuroimaging studies of patients with amyotrophic lateral sclerosis (ALS) have shown widespread alterations in structure, function, and connectivity in both motor and non-motor brain regions, suggesting multi-systemic neurobiological abnormalities that might impact large-scale brain networks. Here, we examined the alterations in the topological organization of structural covariance networks of ALS patients (N = 60) compared with normal controls (N = 60). We found that structural covariance networks of ALS patients showed a consistent rearrangement towards a regularized architecture evidenced by increased path length, clustering coefficient, small-world index, and modularity, as well as decreased global efficiency, suggesting inefficient global integration and increased local segregation.

Frontotemporal dementia (FTD) is a heterogeneous group of neurodegenerative syndromes associated with several causative and susceptibility genes. Herein, we aimed to determine the incidence of the most common causative dementia genes in a cohort of 118 unrelated Greek FTD spectrum patients. We also screened for novel possible disease-associated variants in additional 21 genes associated with FTD or amyotrophic lateral sclerosis. Read More
