Abstract
Epilepsy is a neurological disorder characterised by unprovoked, repetitive seizures caused by abnormal neuronal firing. The Wnt/β-Catenin signalling pathway is involved in seizure-induced neurogenesis, aberrant neurogenesis, neuroinflammation, and hyperexcitability associated with epileptic disorder. Wnt/β-Catenin signalling is crucial for early brain development processes including neuronal patterning, synapse formation, and N-methyl-d-aspartate receptor (NMDAR) regulation. Disruption of molecular networks such as Wnt/β-catenin signalling in epilepsy could offer encouraging anti-epileptogenic targets. So, with a better understanding of the canonical Wnt/-Catenin pathway, we highlight in this review the important elements of Wnt/-Catenin signalling specifically in Mesial Temporal Lobe Epilepsy (MTLE) for potential therapeutic targets.

Eskandrani A, Almusallam E, Alenizi A, Asiri S, Bamogaddam F, Alhameed M, Aldosari MM. Health related quality of life in a Saudi population of patients with epilepsy. NEUROSCIENCES (RIYADH, SAUDI ARABIA) 2023; 28:234-242. [PMID: 37844939 PMCID: PMC10827025 DOI: 10.17712/nsj.2023.4.20230026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 08/08/2023] [Indexed: 10/18/2023]
Abstract
OBJECTIVES To assess the quality of life for epilepsy patients in Saudi Arabia. Epilepsy, one of the most prevalent chronic neurological conditions in the world, frequently results in a low quality of life. METHODS This cross-sectional study analyzed data between September 2020 and September 2021 from 102 adult patients with epilepsy in outpatient clinics department of Epilepsy Program at King Fahad Medical City compared it to 108 healthy controls during the same study period. Sociodemographics and clinical data were gathered using the Arabic version of the Rand 36-Item Short Form Survey (SF-36) questionnaire and the Quality of Life in Epilepsy Inventory (QOLIE-31). RESULTS Patients with epilepsy had lower SF-36 scores when compared to the control for role limitation due to physical health, role limitations due to emotional health, and general health. The QOLIE-31 revealed that gender was associated with energy/fatigue (p=0.028), medication effect (p=0.016), and social function (p=0.003); only social functioning showed a significant association (p=0.023) with employment. CONCLUSION Quality of life for patients with epilepsy was found to be significantly impacted in Saudi Arabia. Certain factors found in this study differentiate it from data that has already been released. This might be due to Arab differences in family support as well as cultural and religious beliefs.

Malekpour M, Salarikia SR, Kashkooli M, Asadi-Pooya AA. The genetic link between systemic autoimmune disorders and temporal lobe epilepsy: A bioinformatics study. Epilepsia Open 2023. [PMID: 36929812 DOI: 10.1002/epi4.12727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 03/11/2023] [Indexed: 03/18/2023] Open
Abstract
OBJECTIVE We aimed to explore the underlying pathomechanisms of the comorbidity between three common systemic autoimmune disorders (SADs) [i.e., insulin-dependent diabetes mellitus (IDDM), systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA)] and temporal lobe epilepsy (TLE), using bioinformatics tools. We hypothesized that there are shared genetic variations among these four conditions. METHODS Different databases (DisGeNET, Harmonizome, and Enrichr) were searched to find TLE-associated genes with variants; their single nucleotide polymorphisms (SNPs) were gathered from the literature. We also did a separate literature search using PubMed with the following keywords for original articles: "TLE" or "Temporal lobe epilepsy" AND "genetic variation," "single nucleotide polymorphism," "SNP," or "genetic polymorphism." In the next step, the SNPs associated with TLE were searched in the LitVar database to find the shared gene variations with RA, SLE, and IDDM. RESULTS Ninety unique SNPs were identified to be associated with TLE. LitVar search identified two SNPs that were shared between TLE and all three SADs (i.e., IDDM, SLE, and RA). The first SNP was rs16944 on the Interleukin-1β (IL-1β) gene. The second genetic variation was ε4 variation of apolipoprotein E (APOE) gene. SIGNIFICANCE The shared genetic variations (i.e., rs16944 on the IL-1β gene and ε4 variation of the APOE gene) may explain the underlying pathomechanisms of the comorbidity between three common SADs (i.e., IDDM, SLE, and RA) and TLE. Exploring such shared genetic variations may help find targeted therapies for patients with TLE, especially those with drug-resistant seizures who also have comorbid SADs.

Abstract
OBJECTIVE Epilepsy is an important public health problem representing 0.6% of the global burden of disease that particularly impacts people living in the lowest income countries where epilepsy incidence may be 10 fold more than in the developed world. The battery of treatments designed to counteract the clinical manifestations of this disease are various and range from a wide spectrum of antiseizure medicationand specific diets, to surgical techniques for resection of the epileptogenic focus. The aim of our study was to describe the State of the art of Epilepsy Surgery (ES) in Africa and examine ways to deal with the high surgical treatment gap. METHODOLOGY In an observational study, we prospectively disseminated questionnaires via email or directly administered to main epileptologists and neurologists involved in epilepsy care, in key African countries. We also conducted a literature search using PubMed, Google scholar on ES in all the African countries. RESULTS We received responses from the majority of African countries, which allowed us to identify 3 levels of care for ES in African countries, a first level that uses ES with invasive presurgical evaluation, a second level that uses ES but without invasive presurgical evaluation, and a third level that does not use ES, and we summarized these results on a map. DISCUSSION This paper studied the availability of ES as a treatment modality in several African countries. We aimed to establish optimal pathways for initiating ES with noninvasive Electroencephalography and readily available investigations. This could be achieved through collaboration with epilepsy programs in developed countries directly or by using telemedicine.
