Although vascular complications after head trauma is well recognized, basilar artery entrapment within the longitudinal clivus fracture is rare. A 69-year-old man presented with progressive disturbance of consciousness and right hemiplegia after trauma. Computed tomography scan showed a right-sided acute subdural hematoma and multiple skull fractures, including a longitudinal clivus fracture. Magnetic resonance imaging revealed basilar artery occlusion and a small infarction at the ventral part of the pons...

Loss-of-function and hypomorphic ECHS1 variants are associated with mitochondrial short-chain enoyl-CoA hydratase deficiency, an inborn error of valine metabolism. We report an 8-year-old boy with developmental delay, ataxia, hemiplegia, and hearing loss with abnormalities in the basal ganglia. Biochemical studies were essentially normal except for a persistent mildly elevated CSF alanine. This patient demonstrates an intermediate phenotype between a Leigh-like, early-onset presentation and paroxysmal exercise-induced dyskinesia...

Complex phenotypes may represent novel syndromes that are the composite interaction of several genetic and environmental factors. We describe an 9-year old male with high functioning autism spectrum disorder and Muckle-Wells syndrome who at age 5  years of age manifested perseverations that interfered with his functioning at home and at school. After age 6, he developed intermittent episodes of fatigue and somnolence lasting from hours to weeks that evolved over the course of months to more chronic hypersomnia...

BACKGROUND: Administration of botulinum neurotoxin A (BoNT-A) to the ankle plantar flexors in patients with hemiplegia reduces the strength of knee extension, which may decrease their walking ability. Studies have reported improvements in walking ability with physical therapy following BoNT-A administration. However, no previous studies have evaluated from an exercise physiology perspective the efficacy of physical therapy after BoNT-A administration for adult patients with hemiplegia...

Childhood-onset schizophrenia (COS) is a rare and severe form of schizophrenia defined as onset before age of 13. Here we report on two unrelated cases diagnosed with both COS and alternating hemiplegia of childhood (AHC), and for whom two distinct pathogenic de novo variants were identified in the ATP1A3 gene. ATP1A3 encodes the α-subunit of a neuron-specific ATP-dependent transmembrane sodium-potassium pump. Using whole exome sequencing data derived from a cohort of 17 unrelated COS cases, we also examined ATP1A3 and all of its interactors known to be expressed in the brain to establish if variants could be identified...

OBJECTIVE: Na+ /K+ -ATPase dysfunction, primary (mutation) or secondary (energy crisis, neurodegenerative disease) increases neuronal excitability in the brain. To evaluate the mechanisms underlying such increased excitability we studied mice carrying the D801N mutation, the most common mutation causing human disease, specifically alternating hemiplegia of childhood (AHC) including epilepsy. Because the gene is expressed in all neurons, particularly γ-aminobutyric acid (GABA)ergic interneurons, we hypothesized that the pathophysiology would involve both pyramidal cells and interneurons and that fast-spiking interneurons, which have increased firing rates, would be most vulnerable...

To explore the clinical value of superselective lingual artery embolization in treating the severe hemorrhage in patients with advanced carcinoma of tongue. Four patients with advanced tongue cancer hemorrhage from March 2014 to February 2016 were enrolled in this study. T3N2M0 (2 cases) and T4N1M0 (2 cases) were diagnosed preoperatively. Two cases of advanced tongue carcinoma tumors had severe bleeding and the other 2 cases of hemorrhage were after radiotherapy. All cases including 3 squamous cell carcinoma and 1 adenocarcinoma were firstly demonstrated by arterigraphy under seldinger technique with digtial subtraction angiogarphy to ensure the rupture site and then all cases were followed by superselective artery embolization...

Here, we present a study on exoskeleton robot control based on inter-limb locomotor synergies using a robot control method developed to target hemiparesis. The robot control is based on inter-limb locomotor synergies and kinesiological information from the non-paretic leg and a walking aid cane to generate motion patterns for the assisted leg. The developed synergy-based system was tested against an autonomous robot control system in five patients with hemiparesis and varying locomotor abilities. Three of the participants were able to walk using the robot...

Vascular arteriovenous malformations (VAM) are aggressive vascular diseases associated with increased haemorrhagic risk in terms of morbidity and mortality. Vascular arteriovenous malformations are usually sporadic. The main symptom of VAM is hemorrhage, in 50% of cases. We here report the case of a 28 year old patient, hospitalized with right sided motor deficit of acute onset associated with consciousness disorder in the Department of Neurology at the Yalgado Ouédraogo University Hospital Center. The patient had a history of chronic headaches treated with self-medication and of right Bravais-Jacksonian seizures...

OBJECTIVE: Heterozygous mutations in the ATP1A3 gene are responsible for various neurological disorders, ranging from early-onset alternating hemiplegia of childhood to adult-onset dystonia-parkinsonism. Next generation sequencing allowed the description of other phenotypes, including early-onset epileptic encephalopathy in two patients. We report on three more patients carrying ATP1A3 mutations with a close phenotype and discuss the relationship of this phenotype to alternating hemiplegia of childhood...

Both hand and finger sensory perception and motor abilities are essential for the development of skilled gestures and efficient bimanual coordination. While finger dexterity and finger sensory perception can be impaired in children with cerebral palsy (CP), the relationship between these two functions in this population is not clearly established. The common assumption that CP children with better sensory function also demonstrate better motor outcomes has been recently challenged. To study these questions further, we assessed both finger dexterity and finger gnosia, the ability to perceive one's own fingers by touch, in groups of 11 children with unilateral (i...

Microdeletions in the 1q44 region encompassing the HNRNPU gene have been associated with infantile spasms and hemiconvulsion-hemiplegia-epilepsy syndrome. Recent studies have revealed that heterozygous HNRNPU variants resulted in early onset epilepsy and severe intellectual disability. A de novo frameshift mutation in HNRNPU was identified in a 5-year-old boy with developmental delay associated with Rett-like features including stereotypic hand movements and respiratory abnormalities with episode of apnea and hyperpnea followed by falling...

Hemiplegia is a symptom that is caused by reduced sensory and motor ability on one side of the body due to stroke-related neural defects. Muscular weakness and abnormal sensation that is induced by hemiplegia usually lead to motor impairments, such as difficulty in controlling the trunk, unstable balance, and poor walking ability. Therefore, most hemiplegia patients show defective and asymmetric gait pattern. The purpose of this study is to distinguish hemiplegic gait by extracting simple characteristics of acceleration signals that are caused by asymmetry during walking using a wearable system...

Hemiconvulsion hemiplegia epilepsy (HHE) syndrome is a rare complication of prolonged focal seizures in children upto 4 years of age. It is usually idiopathic and seen in the setting of febrile seizures in otherwise normal children but less commonly is also associated with structural, infective, traumatic and degenerative diseases that predispose to seizures. It has 3 stages, the first of prolonged focal seizures, then the development of hemiplegia and then followed by final stage of development of epilepsy after a variable latent period...

Mutations in the ATP1A3 gene are known to cause alternating hemiplegia of childhood (AHC) and rapid-onset dystonia parkinsonism (RDP). Both conditions are childhood-onset neurological disorders with distinct symptoms and different times of onset. ATP1A3 has also been associated with CAPOS syndrome (cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss). Within the various ATP1A3 -related neurological syndromes, a specific genotype-phenotype correlation is starting to emerge...
