Abstract
Epilepsy and cerebrovascular accident (stroke) are two common conditions in neurology, the frequency of which increases with age. One of the most common comorbidities after a stroke is epilepsy; nearly 10% of stroke patients will have a seizure immediately or later. The aim of study was to describe the epidemiological, clinical, electrical and evolutionary aspects of post-stroke crises at the Brazzaville University Hospital. This was a cross-sectional study carried out from March 1 to September 30, 2018 in the neurology department of the University Hospital of Brazzaville. It focused on patients over 18 years of age hospitalized for a seizure following a stroke documented by imaging. The epidemiological, electroclinical and therapeutic variables were evaluated. 322 patients hospitalized for stroke, 62 (15.5%) presented with seizures following the vascular event. Men were more affected (57%). The median time to onset of seizures was 2478 days (6.8 years) after stroke. These attacks were early in 69.4% of cases, and most often focal (37.1%). The epileptic seizures were related to the arterial infarctions in 79% of the cases and the abnormalities found on the EEG tracing were consistent with the location of the vascular lesion in 63.6% of the cases. The death rate was 14.5%. The predictive factors of this mortality were: the late onset of epileptic seizures (p=0.048), the presence of hyperglycemia (p=0.006) and the absence of a return to a normal state of consciousness (p<0.001). Post-stroke epileptic seizures are frequent in our region. Secondary prevention of stroke would help reduce the occurrence of strokes and therefore epileptic seizures

Epilepsy and cerebrovascular accident are two common pathologies in neurology, the frequency of which increases with age [1, 2]
Diagnosis of post-stroke epileptic seizures During the study period, 322 patients were hospitalized for stroke and 78 patients were hospitalized for seizures
Sixtytwo (15.5%) of all these patients had at least one epileptic seizure episode following stroke, i.e. 19.2% of the 332 patients hospitalized for stroke and 79.5% of the 78 patients hospitalized for epileptic seizures
Summary
Epilepsy and cerebrovascular accident (stroke) are two common pathologies in neurology, the frequency of which increases with age [1, 2]. Seizures or “acute symptomatic seizures” are not synonymous with epileptic disease [5, 6] It is more often an Sounga Bandzouzi Prince Eliot Galieni et al.: Post-Stroke Epileptic Crises: Profile of Patients at Brazzaville Chu occasional attack, usually occurring within the first 24 - 48 hours, or even the first 7 days after the stroke [5,6,7]. Their frequency varies from 2 to 33%. The objective of this work was to determine the frequency and the epidemiological, clinical, electrical and evolutionary profile of post-stroke crises at the Brazzaville University Hospital
