After playing handball, a 13-year-old girl developed a comatose condition during 7-10 days with hemiparesis and aphasia. From age three to nine she was treated for partial epilepsy. She never had symptoms of migraine. Her father had childhood epilepsy and at the age of 40 and 44 he experienced two attacks with prolonged coma, fever, seizures, hemiparesis and aphasia. His mother had symptoms of severe hemiplegic migraine. Father and daughter were genetically tested and an earlier described mutation in ATP1A2 gene was found. These cases illustrate the phenotypic variability in familial hemiplegic migraine type 2.

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is an uncommon condition represented by an infantile-onset disorder, frequently arising from heterozygous mutations in the gene. Individuals with GLUT1-DS may present with early-onset seizures (typically manifesting before 4 years of age), developmental delay, and complex movement disorders. In fewer cases, stroke-like events or hemiplegic migraine-like symptoms are also reported, defined by unilateral paresis affecting 1 side of the body and/or one-half of the face, occasionally accompanied by speech impairment.

Background: Familial hemiplegic migraine (FHM) types 1-3 are associated with protein-altering genetic variants in , and , respectively. These genes have also been linked to epilepsy. Previous studies primarily focused on phenotypes, examining genetic variants in individuals with characteristic FHM symptoms.

Department of Pediatrics, Seoul National University Children's Hospital, Seoul, Korea.
Background And Purpose: To determine the clinical phenotypes, relapse timing, treatment responses, and outcomes of children with relapsing myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).
Methods: We collected the demographic, clinical, laboratory, and radiological data of patients aged <18 years who had been diagnosed with MOGAD at Seoul National University Children's Hospital between January 2010 and January 2022; 100 were identified as positive for MOG antibodies, 43 of whom experienced relapse.
Results: The median age at onset was 7 years (range 2-16 years).
A Longitudinal Exploration of -Related Hemiplegic Migraine in Children Using Electronic Medical Records.

Division of Neurology, Children's Hospital of Philadelphia, PA.
Background And Objectives: Since the initial description of related hemiplegic migraine (HM), the phenotypic spectrum has expanded from mild episodes in neurotypical individuals to potentially life-threatening events frequently seen in individuals with developmental and epileptic encephalopathies. However, the overall longitudinal course throughout childhood remains unknown.
Methods: We analyzed HM and seizure history from electronic medical records in individuals with -related HM, delineating frequency and severity of events in monthly increments through a standardized approach.

A male in his 20s presented with episodic headache and subsequently developed episodic unilateral weakness, dysphasia and encephalopathy. These paroxysmal episodes persisted over time with the development of background cognitive impairment and neuropsychiatric symptoms. MRI surveillance demonstrated progressive T2 hyperintensity with focal cortical oedema correlating to symptoms observed during clinical episodes.
