BACKGROUND: It is difficult to distinguish between restorative and compensatory mechanisms underlying (pediatric) neurorehabilitation, as objective measures assessing selective voluntary motor control (SVMC) are scarce. METHODS: We aimed to quantify SVMC of elbow movements in children with brain lesions. Children played an airplane game with the glove-based YouGrabber system. Participants were instructed to steer an airplane on a screen through a cloud-free path by correctly applying bilateral elbow flexion and extension movements...

BACKGROUND: Heterogeneous by the underlying pathobiology and clinical presentation, childhood onset dystonia is most frequently progressive, with related disability and limitations in functions of daily living. Consequently, there is an obvious need for efficient symptomatic therapies. METHODS AND RESULTS: Following lesional surgery to basal ganglia (BG) and thalamus, deep brain stimulation (DBS) is a more conservative and adjustable intervention to and validated for internal segment of the globus pallidus (GPi), highly efficient in treating isolated "primary" dystonia and associated symptoms such as subcortical myoclonus...

PURPOSE: To examine the effects of Sensorimotor Training to Affect Balance, Engagement, and Learning (STABEL), a virtual reality system to train sensory adaptation for balance control, for children with fetal alcohol spectrum disorders (FASDs). METHODS: Twenty-three children with FASDs received STABEL training in a university laboratory, or home, or were controls. The Movement Assessment Battery for Children-2nd edition (MABC-2) and Pediatric Clinical Test of Sensory Interaction for Balance-2 (P-CTSIB-2) were analyzed by group (lab, home, and control), session (pre-STABEL, 1 week post-STABEL, and 1 month post-STABEL), and group-by-session interaction...

Narcolepsy with cataplexy is a rare, but important differential diagnosis for daytime sleepiness and atonic paroxysms in an adolescent. A recent increase in incidence in the pediatric age group probably linked to the use of the Pandemrix influenza vaccine in 2009, has increased awareness that different environmental factors can "trigger" narcolepsy with cataplexy in a genetically susceptible population. Here, we describe the case of a 13-year-old boy with narcolepsy following yellow fever vaccination. He carries the HLA DQB1*0602 haplotype strongly associated with narcolepsy and cataplexy...

OBJECTIVES: Alteration in peripheral iron indices has been reported in a number of movement disorders, particularly Parkinson's disease. We hypothesized that iron stores may be diminished in children at an early stage of tic disorder. METHODS: Using data retrieved from electronic medical records, we compared serum ferritin levels, an indicator of body iron store balance, in drug-naive children diagnosed for the first time with tic disorder (study group; N = 47, 32 boys/15 girls, aged 8...

BACKGROUND: Impaired sleep is associated with negative effects on quality of life and daytime functioning. Higher rates of sleep disturbance are reported in children with various developmental disorders. However, little is known about sleep in children with developmental coordination disorder (DCD), a condition characterized by everyday movement difficulties. Previously, in a preliminary study, we found higher rates of parent-reported sleep disturbance in children with DCD compared to controls...

Avoidant/restrictive food intake disorder (ARFID) is a diagnosis in diagnostic and statistical manual of mental disorders-5 (DSM-5) manifested by persistent failure to meet nutritional and/or energy needs. Pudendal nerve entrapment (PNE) often causes pelvic discomfort in addition to constipation and painful bowel movements. Current literature on ARFID is sparse and focuses on the pediatric and adolescent population. No association between PNE and ARFID has been described. We present a case of ARFID in an adult male with PNE resulting from subsequent scarring from testicular cancer surgery...

Extrapontine myelinolysis (EPM) is an uncommon disorder in children, with few pediatric cases reported to date. We report the first case of an infant with EPM without central pontine myelinolysis (CPM) presenting with severe hypernatremia. On admission, the infant had impaired consciousness, mild dehydration, and severe hypernatremia (190 mmol/L). The following day, the patient developed abnormal involuntary movements. Brain magnetic resonance imaging (MRI) confirmed EPM without CPM. He recovered without sequelae, and clinical examinations were within normal limits approximately 6 months after discharge...

Muscle ultrasound is an ideal imaging modality that allows for noninvasive, radiation-free point-of-care neuromuscular imaging. There are many potential applications of muscle ultrasound, including identification of abnormal muscle movements such as fasciculations, evaluation of muscle trauma, identification of physiologic parameters such as pennation angle, accurate performance of chemodenervation, and improved accuracy of challenging electrodiagnostic studies such as phrenic nerve conduction studies or needle electromyogram (EMG) of the diaphragm...

Encephalitis associated with leucine-rich glioma inactivated 1 (LGI1) antibodies is often encountered in elderly male patients and may infrequently present with isolated syndromes. A 6-year-old boy was admitted with acute onset severe oral and facial stereotypic and choreiform movements. On his neurologic examination, he had repetitive and rhythmic movements in orolingual muscles including tongue protrusion, limb chorea and minimal facial stereotypic movements. Anti-streptolysin O (ASO) titers were found severely elevated in several measurements...

BACKGROUND: Interactive neuromodulation represents the evolving frontier in surgical treatment of a variety of disorders involving the sensory organs and nervous system. Building on the advances of pioneering neurologists and neurosurgeons, progress has been made since the introduction of deep brain stimulation (DBS). Microelectrode recording has greatly aided our understanding of the underlying pathogenesis of movement disorders and the effects of electrical stimulation. The introduction of image - guided systems to provide targeted, controlled neuro-stimulation to specific brain areas is an emerging technique for implantation and may have special appeal for pediatric patients...

PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections) syndrome is a disorder seen before adolescence that possesses an abrupt onset of obsessive-compulsive disorder symptoms and/or tics. Swedo and colleagues defined this disorder in 1998 as a syndrome related to Group A streptoccoccus (GAS) infection with neurological issues, such as motor hyperactivation and choreiform movements. The progress of the disorder may be described as wax-and-waning, apart from abrupt onset, and this relapse and remission course is associated with exacerbating infections, according to the creators of PANDAS syndrome...

BACKGROUND: Childhood masturbation (CM) is considered a variant of normal sexual behavior; however, it is commonly misdiagnosed as epilepsy and movement disorders. As the first study from Iran, we analyzed a large population of infants and children with CM in a case-control study and evaluated the value of mucus in urine analysis as an alternative diagnostic tool for CM. METHODS: A total of 623 children referred to the Pediatric Neurology Clinic of Imam Khomeini Hospital for an evaluation of seizure or movement disorders were studied between 2008 and 2011...

Attention-deficit/hyperactivity disorder (ADHD) is a common comorbid disease in children with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), in which tic-like involuntary movements are frequently seen clinical conditions. In contrast to psychostimulants, atomoxetine is considered as having minimal effects on tics. Here we report two cases with ADHD and PANDAS who were treated with atomoxetine for their ADHD and comorbid tics.

In the PI(3,5)P2 biosynthetic complex, the lipid kinase PIKFYVE and the phosphatase FIG4 are bound to the dimeric scaffold protein VAC14, which is composed of multiple heat-repeat domains. Mutations of FIG4 result in the inherited disorders Charcot-Marie-Tooth disease type 4J, Yunis-Varón syndrome, and polymicrogyria with seizures. We here describe inherited variants of VAC14 in two unrelated children with sudden onset of a progressive neurological disorder and regression of developmental milestones. Both children developed impaired movement with dystonia, became nonambulatory and nonverbal, and exhibited striatal abnormalities on MRI...
