Impairments in social cognitive functioning are well documented in schizophrenia, however the neural basis of these deficits is unclear. A recent explanatory model of social cognition centers upon the activity of mirror neurons, which are cortical brain cells that become active during both the performance and observation of behavior. Here, we test for the first time whether mirror neuron functi...

Frontotemporal lobe degeneration (FTLD) refers to a neurodegenerative dementia syndrome, which could be clinically classified into behavioral and language variant. Amyotrophic lateral sclerosis (ALS) is a progressive neurological disorder involving both upper motor neuron (UMN) and lower motor neuron (LMN), eventually leading to muscle atrophy and weakness, bulbar palsy, and respiratory failure...

Spinal muscular atrophy (SMA), a devastating neurodegenerative disorder characterized by motor neuron loss and muscle atrophy, has been linked to mutations in the Survival Motor Neuron (SMN) gene. Based on an SMA model we developed in Drosophila, which displays features that are analogous to the human pathology and vertebrate SMA models, we functionally linked the fibroblast growth factor (FGF)...

Proximal spinal muscular atrophy (SMA) is a motor neuron degeneration disorder for which there is currently no effective treatment. Here, we report three compounds (sodium vanadate, trichostatin A and aclarubicin) that effectively enhance SMN2 expression by inducing Stat5 activation in SMA-like mouse embryonic fibroblasts and human SMN2-transfected NSC34 cells. We found that Stat5 activation en...

As multifocal motor neuropathy (MMN) is a potentially treatable disorder, its differentiation from lower motor neuron disease is important. Evidence of conduction block (CB) is considered one of the relevant criteria for the diagnosis of MMN. Strict criteria for CB may lead to underdiagnosis of MMN, however. Using a standardized examination, we studied the clinical, laboratory, and electrophysi...

De novo heterozygous missense mutations in the gene encoding translation elongation factor eEF1A2 have recently been found to give rise to neurodevelopmental disorders. Children with mutations in this gene have developmental delay, epilepsy, intellectual disability and often autism; the most frequently occurring mutation is G70S. It has been known for many years that complete loss of eEF1A2 in ...

Thirteen children with abnormal mitochondria in muscle tissue, and a progressive neurological disorder that affected the cerebrum, cerebellum, extrapyramidal system, vestibular system, retina, upper motor neuron, lower motor neuron, and musculature, are reported. Other signs and symptoms were short stature, diabetes mellitus, cardiopathy, hypoplastic anaemia, glomerulopathy, and renal tubular d...

PURPOSE The Pediatric Balance Scale (PBS), a modification of Berg's Balance Scale, was developed as a balance measure for school-age children with mild to moderate motor impairments. The purpose of this study was to determine the test-retest and interrater reliability of the PBS. METHODS To determine test-retest reliability, 20 children (aged five to 15 years) with known balance impairments w...
