AI Article Synopsis
- Aphasia, often linked to strokes or brain lesions, can also occur due to prolonged episodes of seizures known as status epilepticus, though this is rare.
- Six patients were studied who experienced prolonged aphasia, primarily linked to structural issues in the left hemisphere of the brain; only three had clinical seizures before or during the episodes.
- All patients showed specific patterns on their EEGs, and their aphasia improved significantly with antiepileptic drug treatment, highlighting the need for EEG assessments in unexplained prolonged aphasia cases.
Article Abstract
Aphasia is a common symptom encountered by clinical neurologists. It is usually caused by strokes or lesions involving language regions of the brain, yet prolonged aphasia is rarely the sole manifestation of a simple partial status epilepticus. We report six patients, who suffered from prolonged ictal aphasia. All but one patient had a structural lesion in the left hemisphere, only three suffered from clinical seizures during or shortly prior to the aphasic episode. All patients had ictal patterns on the electroencephalogram (EEG), four of whom had periodic lateralized epileptiform discharges, and five showed frequent recurrent electrographic seizures during the aphasic state. The aphasia lasted several days in all patients, and it resolved after administration of antiepileptic drug treatment. In conclusion, prolonged ictal aphasia is a rare but important treatable cause of aphasia. Surface EEG recordings should be obtained in all patients with unexplained prolonged aphasia to diagnose this rare but treatable entity.

Article Synopsis
- Tardive seizures are rare, spontaneous seizures that can occur after electroconvulsive therapy (ECT), potentially leading to severe complications like status epilepticus, and the risk factors and management are not well-defined.
- This study aimed to explore the prevalence of tardive seizures in patients undergoing ECT at Razi Hospital over seven years and to identify factors linked to this occurrence.
- The retrospective analysis included 1,931 ECT sessions from 157 patients, revealing a 4.45% incidence of tardive seizures among patients and a prevalence rate of 0.57% for individual sessions.

Department of Neurology, College of Medicine, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia.
Background: Activation procedures (APs) are adopted during routine electroencephalography (rEEG) to provoke interictal epileptiform abnormalities (EAs). This study aimed to observe interictal and ictal (EAs) of different EEG patterns, provoked by various APs.
Methodology: This cross-sectional study was performed in the neurology department of King Fahd hospital of university, Saudi Arabia.

Department of Clinical Neuroscience and Therapeutics, Hiroshima University, Graduate School of Biomedical and Health Sciences, Japan; Epilepsy Center, Hiroshima University Hospital, Japan.
Purpose: The 2HELPS2B score is an invaluable tool for assessing seizure risk in critically ill patients with unconsciousness. However, this can be challenging for non-epileptologists to use owing to its reliance on electroencephalogram (EEG) analysis. Thus, identifying clinical manifestations associated with high 2HELPS2B scores is crucial.

Objective: There is currently scarce data on the electroclinical characteristics of epilepsy associated with synapsin 1 (SYN1) pathogenic variations. We examined clinical and electro-encephalographic (EEG) features in patients with epilepsy and SYN1 variants, with the aim of identifying a distinctive electroclinical pattern.
Methods: In this retrospective multicenter study, we collected and reviewed demographic, genetic, and epilepsy data of 19 male patients with SYN1 variants.
