Role of Genetics in the Etiopathogenesis of Genetic Generalized Epilepsy: A Review of Current Literature

"Until recently; genetic generalized epilepsy (GGE) was believed to be of presumed genetic etiology with no identifiable genetic mutation or demonstrable epigenetic abnormality. A wide range of epileptic disorders has clue for an inherited susceptibility. Monogenic disorders associated with epilepsy mental retardation and structural brain lesion typified by heterotopias; tuberous sclerosis; and progressive myoclonus epilepsies account for about 1 of epilepsies. This review focuses on the role of genetic mutations and epigenetic rearrangements in the pathophysiologic mechanism of GGE. To achieve this; PubMed; EMBASE; and Google Scholar were systematically and comprehensively searched using keywords (""epilepsy"" ""juvenile myoclonic epilepsy (JME);"" ""typical absences;"" ""idiopathic generalized epilepsy;"" ""JME;"" ""juvenile absence epilepsy;"" ""childhood absence epilepsy"" ""generalized tonic-clonic seizure"" ""GTCS""). Most GGE has evidence of underlying genetic inheritance. Recent animal studies have shown that early detection and treatment of genetic generalized epilepsies can alter the phenotypic presentation in rodents. These findings suggest a critical period in epileptogenesis; during which spike-and-wave seizures can be suppressed; leading to chronic changes in the brain (epileptogenesis) and the preceding dysfunctions may; therefore; be targeted using therapeutic approaches that may either delay or inhibit the transition to active epileptic attack. The interplay between genetic mutations and epigenetic rearrangements play important roles in the development of GCE and that this process; especially at crucial developmental periods; is very susceptible to environmental modulations"

Epilepsy among Elderly Sudanese Patients

Objective: The aim of this study was to evaluate the clinical presentation and characteristics of elderly Sudanese patients with epilepsy. Methodology: This is a prospective study (from Feb. 2005 to Jun 2008). The study population included 240 elderly epileptic patients (age 60 years or above). Results: Cerebrovascular accident was found to be the most common cause of secondary epilepsy (31).Generalize epilepsy was seen in 120 (50) of patients. Abnormal neurological findings were more common (49) among patients with partial epilepsy. Fifty percent of our patients showed abnormal EEG. Abnormal CT brain findings were common among patients with partial epilepsy. Conclusion: The pattern of clinical presentation of epilepsy among elderly Sudanese epileptic patients is similar to what was mentioned in the literature except that the percentage of epilepsy following infections was more among our studied group (6

Epilepsy in Nigeria - A Review of Etiology; Epidemiology and Management

Epilepsy is a major public health issue especially in developing African countries. The etiologies and approach to management are significantly different in developed and developing countries; with infectious causes and treatment with phenobarbitone being the peculiarities of the developing sub-Saharan African countries. This review emphasizes the peculiar etiological considerations; epidemiology and treatment options of epilepsy in Nigeria; and also compares these with the practice of epilepsy management in other African and developed countries
