The authors describe the so-called benign convulsions of infancy and confirm the existence of benign nonfamilial infantile convulsions during the first 2 years of life and their benign course. The authors evaluated 58 patients: 17 subjects had a family history of benign epilepsy, and 41 did not. No clinical differences were observed between the two groups.

Dravet syndrome (DS) is a developmental and epileptic encephalopathy (DEE) that begins in the first year of life. While most cases of DS are caused by variants in SCN1A, variants in SCN1B, encoding voltage-gated sodium channel β1 subunits, are also linked to DS or to the more severe early infantile DEE. Both disorders fall under the OMIM term DEE52.

Although many reports have described the characteristics of Williams-Beuren syndrome, few specifically analyzed epilepsy in patients with Williams-Beuren syndrome. In this retrospective study, we map the prevalence, types, and prognosis of epileptic seizures in a large cohort of 589 patients with Williams-Beuren syndrome, as well as associations between deletions of the membrane-associated guanylate kinase inverted-2-gene (2 gene), which is associated with infantile spasms (IS), and epilepsy in patients with Williams-Beuren syndrome.Our findings indicate that the incidence of epilepsy in patients with Williams-Beuren syndrome is approximately 1.

Epilepsy is one of the most common neurological disorders affecting approximately 50 million people worldwide. It impacts people of all genders and ages, but evidence suggests a higher incidence rate in children and the elderly. Given that childhood epilepsy has the risk of causing developmental epileptic encephalopathy, which is associated with intellectual, behavioral, and/or motor disabilities, proper assessment of children with new-onset epilepsy at an early stage is essential to prevent threats affecting neurodevelopmental processes.

Purpose Of Review: Prader-Willi (PWS) and Angelman (AS) syndromes arise from errors in 15q11-q13 imprinting. This review describes recent advances in genomics and how these expand our understanding of these rare disorders, guiding treatment strategies to improve patient outcomes.
Recent Findings: PWS features include severe infantile hypotonia, failure to thrive, hypogonadism, developmental delay, behavioral and psychiatric features, hyperphagia, and morbid obesity, if unmanaged.

Pathogenic variants are associated with neonatal epilepsies, ranging from self-limited neonatal epilepsy to -developmental and epileptic encephalopathy (DEE). In this study, next-generation sequencing was performed, applying a panel of 142 epilepsy genes on three unrelated individuals and affected family members, showing a wide variability in the epileptic spectrum. The genetic analysis revealed two likely pathogenic missense variants (c.
