Molecular Screening of SCN1A‐Related Seizures in Children With Febrile Seizures: Diagnostic Yield and Variant Distribution

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SCN1A‐related seizures first present as febrile seizures (FS). Definitive features emerge later, making early diagnosis challenging. We evaluated the diagnostic yield and clinical characteristics of pathogenic SCN1A variants in FS, and analyzed the effect of variant characteristics on clinical phenotypes required for early ...

Time‐Frequency Fingerprint Analysis in SEEG Source‐Space to Identify the Epileptogenic Zone

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This case study highlights the application of seizure fingerprint analysis in the source‐space of stereo‐EEG (SEEG) data to accurately localize the epileptogenic zone (EZ) in patients with complex cortical malformations. A 25‐year‐old female with extensive bilateral perisylvian polymicrogyria (PMG) presented with intractable focal seizures ...

Real‐World Comparison of High‐Efficacy Versus Non‐High‐Efficacy Therapies in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choice of the first disease modifying treatment (DMT) in multiple sclerosis (MS) is a topic of great interest, and whether high‐efficacy DMTs should be the first choice remains debated. We compared treatment outcomes (no evidence of disease activity [NEDA] and its components) between treatment‐naïve relapsing–remitting MS (RRMS ...
