OBJECTIVE Amyotrophic lateral sclerosis (ALS) is a common, fatal motor neuron disorder with no effective treatment. Approximately 10% of cases are familial ALS (FALS), and the most common genetic abnormality is superoxide dismutase-1 (SOD1) mutations. Most ALS research in the past decade has focused on the neurotoxicity of mutant SOD1, and this knowledge(More)
The uncinate fasciculus interconnects the anterior temporal and inferior frontal lobes. The temporal lobes show a number of anatomical asymmetries, some of which are altered in schizophrenia. This study was performed to assess the size and symmetry of the uncinate fasciculus in normal subjects and in patients with the disorder. The area, fibre density and(More)
Mutation in the CHMP2B gene has been implicated in frontotemporal dementia. The authors screened CHMP2B in patients with ALS and several cohorts of control samples. They identified mutations (Q206H; I29V) in two patients with non-SOD1 ALS. Neuropathology of the Q206H case showed lower motor neuron predominant disease with ubiquitylated inclusions in motor(More)
OBJECTIVE It has been suggested that the primary focus of the pathological process in schizophrenia is on the limbic system, and there have been several postmortem reports of changes in the histological structure or volume of the hippocampus, as well as a larger number of MRI reports of volume reductions. There are conflicting findings, however, with both(More)
Intronic expansion of the GGGGCC hexanucleotide repeat within the C9ORF72 gene causes frontotemporal dementia and amyotrophic lateral sclerosis/motor neuron disease in both familial and sporadic cases. Initial reports indicate that this variant within the frontotemporal dementia/amyotrophic lateral sclerosis spectrum is associated with transactive response(More)
Alterations, sometimes sex-dependent, in volumes and gyral structure of areas of cerebral cortex have been reported in schizophrenia. Such changes imply an anomaly of connectivity. The gyrification, percentage of tissue volume attributed to white matter, cortical volume and white matter volume were measured from magnetic resonance images in males and(More)
OBJECTIVE To determine the frequency of and clinicopathologic phenotypes associated with FUS/TLS mutations in a large cohort of amyotrophic lateral sclerosis (ALS) cases from the north of England. DESIGN Genetic screening project with neuropathologic examination of postmortem tissue in selected cases. The clinical details of selected cases are also(More)
GGGGCC repeat expansions of C9orf72 represent the most common genetic variant of amyotrophic lateral sclerosis and frontotemporal degeneration, but the mechanism of pathogenesis is unclear. Recent reports have suggested that the transcribed repeat might form toxic RNA foci that sequester various RNA processing proteins. Consensus as to the identity of the(More)
OBJECTIVE To determine the histopathologic bases for the observed incidence of parkinsonism in families with C9ORF72 expansions, which typically cause amyotrophic lateral sclerosis (ALS) and/or frontotemporal dementia. METHODS DNA was extracted from 377 brains with the histopathologic diagnosis of idiopathic Parkinson disease or related disorders and(More)
Research into amyotrophic lateral sclerosis (ALS) has been stimulated by a series of genetic and molecular pathology discoveries. The hallmark neuronal cytoplasmic inclusions of sporadic ALS (sALS) predominantly comprise a nuclear RNA processing protein, TDP-43 encoded by the gene TARDBP, a discovery that emerged from high throughput analysis of human brain(More)
