Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

SERPINI1pathogenic variants: An emerging cause of childhood-onset progressive myoclonic epilepsy

, 2017
Progressive myoclonic epilepsies are rare neurodegenerative diseases with a wide spectrum of clinical presentations and genetic heterogeneity that render their diagnosis perplexing.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Unraveling 4‐Phenylbutyrate's Therapeutic Role in SLC6A1 Disorders: Pharmacochaperoning Over HDAC Inhibition

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Variants in SLC6A1, encoding the GABA transporter 1 (GAT‐1), cause epilepsy, autism spectrum disorder, and developmental delay via loss of GABA uptake, impaired trafficking, and ER retention. We previously found that 4‐Phenylbutyrate (PBA), an FDA‐approved drug, restores GABA uptake and reduces seizures in SLC6A1‐related disorders ...

Progressive myoclonic encephalopathies: From phenomenology to genes and proteins

, 2012
The progressive myoclonic epilepsies (PMEs) are a group of symptomatic generalized epilepsies caused by rare disorders, most of which have a genetic component, a debilitating course, and a poor outcome.

Monoallelic POLR3A Variants Cause Early‐Onset Peripheral Neuropathy

Annals of Neurology, EarlyView.
Objective Biallelic variants in genes encoding the RNA polymerase III complex (Pol III) cause a spectrum of neurological disorders primarily affecting the central nervous system. Monoallelic variants have been reported in the POLR3B subunit only, associated with neurodevelopmental disorder, epilepsy, and peripheral neuropathy.

Epilepsy characteristics in patients with muscle‐eye‐brain disease: A systematic review of electroclinical features

Epileptic Disorders, EarlyView.
Abstract Background and Objectives Muscle‐Eye‐Brain disease (MEB) is a dystroglycanopathy that belongs to the congenital muscular dystrophies. Central nervous system manifestations include congenital brain abnormalities, neurodevelopmental delay, and epilepsy, making it a rare but important cause of developmental and epileptic encephalopathy.

Degenerative Progressive Myoclonic Epilepsy Electrokymographic Observations [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1979
SummaryClinical and pathological findings in two cases of degenerative progressive myoclonic epilepsy (PME) are described. The clinically difficult task of differentiating a “cerebellar” tremor from an action myoclonus is emphasized. Simultaneous elect roencephalography and electrokymography was done, using capacity to ground transients for recording ...

Seminars in epileptology: Holistic management of epilepsy in adults with intellectual development disorders

Epileptic Disorders, EarlyView.
Abstract This seminar addresses the complexity of the management of epilepsy in adults with intellectual development disorders (IDD), advocating holistic and multidisciplinary care aligned with the learning objectives of the International League Against Epilepsy. Epilepsy is significantly more prevalent in people with IDD, presenting unique diagnostic,
