Perampanel reduces seizure frequency in patients with developmental and epileptic encephalopathy for a long term.

Seizures in patients with developmental and epileptic encephalopathies (DEEs) are often highly resistant to various antiseizure medications. Perampanel (PER) is a novel antiseizure medication that non-competitively inhibits the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor and is expected to reduce seizure frequency not only for focal seizures and generalized tonic-clonic seizures (GTCS) but also for other seizure types. This study aimed to clarify the long-term therapeutic efficacy and tolerability of PER in patients with DEEs.

Efficacy of parent-child interaction therapy for children born premature.

Background: Premature children are known to be at a high risk of developing behavioral problems. This study examined the effectiveness of parent-child interaction therapy (PCIT) in reducing behavioral problems in young children born premature.

Methods: The study included 18 child-parent pairs with children born at less than 35 weeks of gestation (range: 23-34 weeks, median: 31.

Prognostic factors, psychomotor development and life of trisomy 13 patients.

Background: Infants with trisomy 13 have a very high mortality rate. However, aggressive interventions for their complications, can improve their prognosis and may, thereby, increase the number of long-term survivors with trisomy 13. To date, there is no study on the psychomotor developmental progress of patients with trisomy 13.

A TUBB4A Met363Thr variant in pediatric hypomyelination without atrophy of the basal ganglia.

TUBB4A gene variants cause dystonia type 4 and hypomyelination with atrophy of the basal ganglia and cerebellum. We report the case of a child with delayed motor development, intellectual disability, and dystonia. Magnetic resonance imaging revealed hypomyelination and progressive cerebellar atrophy without atrophy of the basal ganglia.

Developmental changes of the neural mechanisms underlying level 2 visual perspective-taking: A functional near-infrared spectroscopy study.

The ability to understand the way other people see the world differs from one's own viewpoint is referred to as ''visual perspective-taking'' (VPT). Previous studies have demonstrated the behavioral performance in level 2 VPT (VPT2), the ability to understand that two different observers can have unique visual experiences of the same scene or object depending on the observers' physical location, changes during childhood. However, the developmental aspects underlying the neural mechanisms of VPT2 remains unknown.

Greater reliance on proprioceptive information during a reaching task with perspective manipulation among children with autism spectrum disorders.

Difficulties with visual perspective-taking among individuals with autism spectrum disorders remain poorly understood. Many studies have presumed that first-person visual input can be mentally transformed to a third-person perspective during visual perspective-taking tasks; however, existing research has not fully revealed the computational strategy used by those with autism spectrum disorders for taking another person's perspective. In this study, we designed a novel approach to test a strategy using the opposite-directional effect among children with autism spectrum disorders.

MOG-Ab titer-guided approach for steroid tapering to prevent relapse in children with mog antibody-associated adem diseases: A case report.

Intravenous corticosteroids have been regarded as the first-line therapy of anti-myelin-oligodendrocyte glycoprotein antibody (MOG-Ab)-positive acute disseminated encephalomyelitis (ADEM). While steroids are the first-choice therapy, MOG-Ab-positive ADEM has a high relapse rate. In some cases, MOG-Ab-positive ADEM relapses even in a low-MOG-Abs state.

Acute administration of methylphenidate differentially affects cortical processing of emotional facial expressions in attention-deficit hyperactivity disorder children as studied by functional near-infrared spectroscopy.

It has been reported that children with attention-deficit hyperactivity disorder (ADHD) have impairment in the recognition of angry but not of happy facial expressions, and they show atypical cortical activation patterns in response to facial expressions. However, little is known about neural mechanisms underlying the impaired recognition of facial expressions in school-aged children with ADHD and the effects of acute medication on their processing of facial expressions. We aimed to investigate the possibility that acute administration of methylphenidate (MPH) affects processing of facial expressions in ADHD children.

Does culture shape face perception in autism? Cross-cultural evidence of the own-race advantage from the UK and Japan.

Autism spectrum disorders (ASD) are associated with face perception atypicalities, and atypical experience with faces has been proposed as an underlying explanation. Studying the own-race advantage (ORA) for face recognition can reveal the effect of experience on face perception in ASD, although the small number of studies in the area present mixed findings. This study probed the ORA in ASD by comparing two cultural groups simultaneously for the first time.

Serum and cerebrospinal fluid cytokines in children with acute encephalopathy.

Background: The pathogenesis of acute encephalopathy (AE) remains unclear, and a biomarker has not been identified.

Methods: Levels of 49 cytokines and chemokines, including osteopontin (OPN), were measured in serum and cerebrospinal fluid (CSF) of children with AE (n = 17) or febrile convulsion (FC; n = 8; control group). The AE group included acute necrotizing encephalopathy (n = 1), acute encephalopathy with biphasic seizures and late reduced diffusion (AESD; n = 3), clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS; n = 4), and unclassified acute encephalopathy (UCAE; n = 9) that does not meet the criteria of syndrome classification.

Distinct Methylphenidate-Evoked Response Measured Using Functional Near-Infrared Spectroscopy During Go/No-Go Task as a Supporting Differential Diagnostic Tool Between Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder Comorbid Children.

Attention deficit/hyperactivity disorder (ADHD) has been frequently reported as co-occurring with autism spectrum disorder (ASD). However, ASD-comorbid ADHD is difficult to diagnose since clinically significant symptoms are similar in both disorders. Therefore, we propose a classification method of differentially recognizing the ASD-comorbid condition in ADHD children.

Erratum: Adaptive algorithm utilizing acceptance rate for eliminating noisy epochs in block-design functional near-infrared spectroscopy data: application to study in attention deficit/hyperactivity disorder children.

Atypical neural modulation in the right prefrontal cortex during an inhibitory task with eye gaze in autism spectrum disorder as revealed by functional near-infrared spectroscopy.

Autism spectrum disorder (ASD) is characterized by impairment in social communication and the presence of restricted and repetitive behaviors and interests. Executive function impairment is reportedly partially responsible for these symptoms. Executive function includes planning, flexibility, and inhibitory control.

Rituximab was effective for acute disseminated encephalomyelitis followed by recurrent optic neuritis with anti-myelin oligodendrocyte glycoprotein antibodies.

Background: The effect of rituximab on acute disseminated encephalomyelitis (ADEM) followed by recurrent optic neuritis (ON) is not yet known.

Patient: We are reporting the case of a 4-year-old Japanese girl who was diagnosed with anti-myelin oligodendrocyte glycoprotein (MOG) antibody positive ADEM followed by recurrent ON. She developed altered mental status, left facial paralysis, left paresis, and experienced three episodes of ON.

A case of severe Alexander disease with de novo c. 239 T > C, p.(F80S), in GFAP.

Alexander disease (AxD) is a progressive neurodegenerative disease caused by a mutation in the glial fibrillary acid protein (GFAP) gene. A 4-year-old boy presented several times with hemiclonic seizures with eye deviation for a few minutes at 28 days after birth. Electroencephalogram showed independent sharp waves in the right and left temporal area.
