Introduction: Epilepsy is one of the most common serious chronic neurological diseases, affecting people of all ages worldwide. It is present in several clinical forms, of which the EEG constitutes a preferred examination for diagnosing this disease. This paper focuses on studying the results of the EEG requested for epilepsy and/or generalized tonic-clonic seizure in order to establish the electro-clinical correlation.
Materials and Methods: This is a retrospective and descriptive study that took place over a period of one year from July 2018 to June 2019 at the neurology department, CHU Fann Dakar.
Results: Out of 3960 patients seen during the study period, 295 patients were retained after inclusion and exclusion criteria. The average age was 10.32 years. The male predominance is noted in our study population with a sex ratio of 1.78. In 44.74% of cases, our patients lived in urban areas. Among our patients, 15.25% of the patients presented EEG signs in favor of generalized tonic-clonic seizures on the waking EEG and 38.98% on the sleep EEG.
Conclusion: The request for the EEG requires a rigorous clinical description and must be performed as early as possible to improve sensitivity. In the case of epilepsy or generalized tonic-clonic seizure, the clinical and electrical correlation was around 15 to 39% in the interictal EEG examinations in 48 hours after the last seizure. Some patients may have a normal EEG, which does not rule out the diagnosis of epilepsy and/or generalized tonic-clonic seizures, hence the importance of good clinical analysis in epilepsy.
