Benign myoclonic epilepsy of infancy is recognized as a generalized and idiopathic epilepsy by the International League Against Epilepsy. Unprovoked and reflex seizures have been reported in these patients. We describe a child diagnosed with benign myoclonic epilepsy of infancy, whose strictly unilateral and localized reflex myoclonias broaden the clinical spectrum of this idiopathic and generalized epileptic syndrome, and raise interrogations about its underlying pathophysiological mechanisms.

Clinical, etiological, and therapeutic profile of early-onset absence seizures: A case series analysis.

Typical absence seizures represent a distinctive form of epileptic activity typically observed in pediatric populations, predominantly manifesting between the ages of 4 and 10, constituting Childhood Absence Epilepsy (CAE). However, a subset of patients presents with Early-onset Absence Epilepsy (EOAE), characterized by seizure onset before the fourth year of life, often displaying favorable outcomes with antiseizure medication. Conversely, atypical absence seizures exhibit prolonged duration and frequently entail tonic, atonic, or myoclonic motor elements, suggesting a more severe clinical course, commonly associated with epileptic encephalopathies of childhood onset.

Article Synopsis
- Fenfluramine is a medicine used to help control seizures in kids and adults with two conditions called Dravet syndrome and Lennox-Gastaut syndrome.
- Doctors have found that it works well for these seizures, especially when other treatments haven't worked.
- This review shares stories of four patients and gives doctors advice on using fenfluramine safely, including possible side effects and how to manage the treatment.
Redefined giant somatosensory evoked potentials: Evoked epileptic complexes of excitatory and inhibitory components.

Department of Epilepsy, Movement Disorders and Physiology, Kyoto University Graduate School of Medicine, Japan. Electronic address:
Objective: Giant somatosensory evoked potentials (SEPs) are observed in patients with cortical myoclonus. Short-latency components (SLC), are regarded as evoked epileptic activities or paroxysmal depolarization shifts (PDSs). This study aimed to reveal the electrophysiological significance of the middle-latency component (MLC) P50 of the SEPs.

Paroxysmal kinesigenic dyskinesia (PKD) represents the most prevalent form of paroxysmal dyskinesia, characterized by recurrent and transient attacks of involuntary movements triggered by a sudden voluntary action. In this study, whole-exome sequencing was conducted on a cohort of Chinese patients to identify causal mutations. In one young female case, a de novo variant (NM_000718.
