RESUMEN
BACKGROUND AND PURPOSE: Various risk factors have been described in the literature that increase the risk of seizures associated with stroke. This study was aimed to determine the occurrence rate of poststroke seizures (PSSs) and the associated risk factors in Arab population. MATERIALS AND METHODS: Study included all stroke patients aged >18 years with a minimum follow-up of 24 months following stroke to identify seizure occurrence. Patient's hospital records for all admissions and clinic visits were reviewed. Seizures were classified into early PSS if they occur within 1 week of stroke, and late PSS if they occur after 1 week of stroke. RESULTS: Out of 594 patients, 380 were males. Seizure occurrence was higher in anterior circulation infarctions (94.8%, P < 0.05), cortical location (80.5%, P < 0.05), large artery atherosclerosis (63.8%, P < 0.05), lower activated partial thromboplastin time (APTT) (P = 0.0007), patients with ischemic heart disease (IHD) (P = 0.01), and those who underwent craniotomy (P = 0.001). Nonhigh-density lipoprotein cholesterol was inversely related to PSS (P = 0.01). Higher stroke severity (89%) and confusion (67%) at the time of presentation were independently related to PSS. CONCLUSIONS: Eighty-two (13.8%) patients had PSS. Greater stroke severity at presentation with altered sensorium was independent risk factors for the development of PSS. Patients with underlying IHD, lower APTT, and undergoing neurosurgical intervention require vigilant monitoring for PSS.
Résumé Ontexte et objectif:Divers facteurs de risque ont été décrits dans la littérature qui augmentent le risque de convulsions associées à un AVC. Cette étude visait à déterminer le taux d'occurrence des crises post-AVC (PSS) et les facteurs de risque associés dans la population arabe.Matériels et Méthodes:L'étude a inclus tous les patients victimes d'AVC âgés de plus de 18 ans avec un suivi minimum de 24 mois après l'AVC pour identifier la survenue d'une crise. Les dossiers hospitaliers des patients pour toutes les admissions et visites à la clinique ont été examinés. Les saisies ont été classées en premiers PSS s'ils surviennent dans la semaine suivant l'AVC, et PSS tardif s'ils surviennent après 1 semaine de l'AVC.Résultats:Sur 594 patients, 380 étaient des hommes. Crise d'épilepsie la fréquence était plus élevée dans les infarctus de la circulation antérieure (94,8 %, P < 0,05), la localisation corticale (80,5 %, P < 0,05), l'athérosclérose des grandes artères (63,8 %, P < 0,05), un temps de thromboplastine partielle activé (APTT) inférieur (P = 0,0007), les patients atteints de cardiopathie ischémique (IHD) (P = 0,01) et ceux ayant subi une craniotomie (P = 0,001). Le cholestérol des lipoprotéines non de haute densité était inversement lié au PSS (P = 0,01). Course supérieure la gravité (89 %) et la confusion (67 %) au moment de la présentation étaient indépendamment liées au PSS.Conclusions:Quatre-vingt-deux (13,8 %) patients avait PSS. Une plus grande gravité de l'AVC lors de la présentation avec un sensorium altéré était un facteur de risque indépendant pour le développement du PSS. Les patients avec une IHD sous-jacente, un APTT inférieur et une intervention neurochirurgicale nécessitent une surveillance vigilante du PSS.

BACKGROUND: The occurrence of seizures following a stroke is a well-recognized complication associated with a significant increase in morbidity and mortality. Despite the numerous studies examining outcomes and risk factors related to post-stroke seizures (PSS), there remains a lack of clarity regarding the clinical characteristics, treatment, and PSS recurrence (PSSR) rates in patients experiencing their initial episode of PSS. PURPOSE: This study aimed to determine the risk factors for developing recurrent seizures after first PSS and their effects on functional outcomes and mortality. METHODS: All patients underwent an electroencephalography (EEG) and were monitored for a minimum of 24 months following the first PSS. The primary endpoint was the recurrence of seizures. Predictive factors for PSSR were determined by using the Cox-proportional hazards model, and the cumulative latency of recurrence at 90, 180, 360, and 720 days was estimated using Kaplan-Meier analysis. RESULTS: Seizure recurred in 36.8% (39/106). Significant association of PSSR was noted with female gender, use of older anti-seizure medications (ASMs) (p<0.001), EEG findings as focal slow wave activity (p<0.001), Ictal epileptiform abnormalities (p=0.015), status epilepticus (p=0.015), and with severe disability (p=0.008). However, multivariate cox-proportional hazards model showed significant association of female gender (HR=3.28; 95% CI: 1.42-7.58; p=0.006). Hazard ratio (HR) was increased with older ASMs use, focal aware seizure types, Ictal EAs, and periodic discharges on EEG; though, statistically significant. CONCLUSION: Factors such as the type of ASMs, EEG findings, and seizure type were significantly linked to PSSR. Female gender was the only independent predictor established. Additionally, significant functional decline was reported with recurrence.

Objective: Post-stroke seizures (PSS) are one of the major stroke-related complications. Early therapeutic interventions are critical therefore using electroencephalography (EEG) as a predictive tool for future recurrence may be helpful. We aimed to assess frequencies of different EEG patterns in patients with PSS and their association with seizure recurrence and functional outcomes. Methods: All patients admitted with PSS were included and underwent interictal EEG recording during their admission and monitored for seizure recurrence for 24 months. Results: PSS was reported in 106 patients. Generalized slow wave activity (GSWA) was the most frequent EEG pattern observed (n = 62, 58.5%), followed by Focal sharp wave discharges (FSWDs) (n = 57, 55.8%), focal slow wave activity (FSWA) (n = 56, 52.8%), periodic discharges (PDs) (n = 13, 12.3%), and ictal epileptiform abnormalities (n = 6, 5.7%). FSWA and ictal EAs were positively associated with seizure recurrence (p < .001 and p = .015 respectively) and it remained significant even after adjusting for age, sex, stroke severity, stroke subtype, or use of anti-seizure medications (ASMs). Other positive associations were status epilepticus (SE) (p = .015), and use of older ASM (p < .001). FSWA and GSWA in EEG were positively associated with severe functional disability (p = .055, p = .015 respectively). Other associations were; Diabetes Mellitus (p = .034), Chronic Kidney Disease (p = .002), use of older ASMs (p = .037), presence of late PSS (p = .021), and those with Ischemic stroke (p = .010). Conclusions: Recognition and documentation of PSS-related EEG characteristics are important, as certain EEG patterns may help to identify the patients who are at risk of developing recurrence or worse functional outcomes.
RESUMEN
Background: Spontaneous simultaneous bilateral basal ganglia hemorrhage (SSBBGH) is an extremely rare condition with only a few published case reports and series. However, there is no systematic review that has been published yet. Objective: The study aims to conduct a systematic review on spontaneous simultaneous bilateral basal ganglion bleeding and a descriptive statistical analysis of collected data on epidemiology, clinical features, etiology, therapeutic approach and prognosis. This review aims to be a clinical reference for busy clinicians when they are faced with such a rare condition. Methodology: This review has been carried out in accordance with recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Results: Review of 60 cases showed that SSBBGH affected predominantly male patients (70%) with an average age of 50.8 ± 15.33 years and the male-to-female ratio was 2.5:1. The female patients tend to be older with an average age of 54.22 ± 16.67 years. Location of SSBBGHwas more common in the putamen (90% vs 10% non-putaminal). SSBBGH posed a significant mortality rate (33.33%). Among patients who survived, only 40.6% (13/32 report) have had favorable outcomes (mRS ≤2) and the remaining 59.4% (19/32) ended up with poor functional status (mRS ≥3-5). The most common implicated etiologies were hypertension followed by alcohol intoxication. Conclusion: SSBBGH is a rare clinical entity with significant morbidity and mortality. Systemic approach can lead to early recognition of etiology and prompt treatment. Hypertension and the putamen are the most common etiology and location of SSBBGH, respectively. History of hypertension and age can help narrow differential diagnosis and limit unnecessary testing or intervention.

BACKGROUND: Severe acute respiratory syndrome coronavirus (SARS-CoV-2) due to novel coronavirus disease 2019 (COVID-19) has led to an unprecedented worldwide pandemic with diverse respiratory symptoms as well as systemic manifestations and complications. The neurological manifestations of COVID-19 include, but are not limited to, headache, cerebrovascular disease, and skeletal muscle injury. CASE REPORT: Herein, we present a case of stroke with large vessel occlusion in a middle-aged man, who recently recovered from severe SARS-CoV-2 infection. This patient is not known to have any medical illness or surgical history and has no cerebrovascular risk factors. Moreover, the patient underwent extensive investigations, including neuroimaging, cardiac and laboratory work-up with no evidence of stroke etiology. CONCLUSION: The mechanism of cerebrovascular events in the setting of COVID-19 is still uncertain and probably multi-factorial. The prevailing hypothesis is a strong thrombotic tendency, which may even be prolonged after complete recovery. In our patient's case, hypercoagulability in the context of viral infection is the most likely mechanism for the stroke. Further studies are needed to find out the exact pathogenesis of thromboembolic events in the setting of COVID-19 infection as well as the efficacy, safety, dosage, and duration of anticoagulants in such conditions.
RESUMEN
Free-floating thrombus (FFT) of the cervicocranial arteries is a rare neurovascular condition. Up to now, there is no standardized definition for FFT. Therefore, FFT is occasionally mistaken for intraluminal thrombus (ILT) or smooth mural thrombus. The most precise and ideal definition of FFT would be a long-extended intraarterial thrombus that is attached to the arterial wall with its one end, while its other end is surrounded by blood flow and moves freely with the cardiac cycle. FFT usually manifests as an ischemic stroke, thus it is considered as an emergency case. Herein, we report a rare case of symptomatic FFT in the left vertebral artery extending from V0 to V2 segments in a middle-aged smoker, who presented with multiple embolic strokes in different territories of posterior circulation and was successfully treated medically. This case sheds light on the challenges of the clinical approach of FFT in the vertebral artery and it is an attempt to draw attention to the necessity of conducting a large-scale study to find out the ideal approach to manage such conditions.
RESUMEN
Background: Pre-school children use digital devices both at home and in kindergarten for communication. However, such technologies can also be used for creativity learning and entertainment. Technology usage might exert a negative impact on the psychosocial development of pre-school children, thus necessitating parental monitoring. Previous studies have recommended early intervention for pre-school children by decreasing the duration of digital devices, spending more time with the family, and participation in motor activities to avoid the ill effects of technology. Aim: To investigate the impact of digital device use on the behavioral and sleep scores of preschool children as perceived by parents in Saudi Arabia (SA). Method: This cross-sectional study was conducted across two regions in SA. It was ethically approved by the ethical review board of Imam Abdulrahman Bin Faisal University. The participants were randomly selected from well-baby hospital records, surveyed and interviewed to obtain data for the following measures: demographic data, technology usage, sleep disturbance scale, and behavior scale. Children with special needs or comorbidities were excluded from the study. Descriptive and multivariate regression analysis were done. Results: We recruited 288 children. Most did not attend schools (63.2%), 22.6% were in kindergarten, and 14.2% were in nursery schools. Smart phones were the most commonly used device by the children (42.4%). Most used the technology for 2-3 h/days (34%). Cartoons were the most commonly sought content (42%). The behavior scores for children aged 18-36 months showed a mean value of 5.1, 3.7, and 4.6 for surgency, negative affect, and effortful control, respectively. Children aged 3-5 years showed a mean value of 4.3, 4, and 4.7 for surgency, negative affect, and effortful control, respectively. Sleep disturbance scores for all children showed a mean value of 12.4, 3.5, 3.8, 8, 7.3, and 2.7 on disorders of initiating and maintaining sleep, sleep-breathing disorders, disorders of arousal, sleep-wake transition disorders, disorders of excessive somnolence, and sleep hyperhidrosis, respectively. The mean total sleep score was 37. Multivariate regression analysis showed significant positive relationship between surgency and three factors namely family income of 10,000-15,000 SR (t = 1.924, p = 0.045), fathers' bachelor's degrees (t = 2.416, p = 0.16), and owning a video game device (t = 2.826, p = 0.005<0.05). Negative affect was significantly associated with fathers' diploma level of education (t = 2.042, p = 0.042). Negative significant relationship between effortful control and fathers' secondary level of education (t = -2.053, p = 0.041). There was a significant negative relationship between effortful control and owning a TV and video game device (t = -2.35, -2.855, p = 0.043, 0.005<0.05, respectively). A significant positive relationship was found between child's sleeping score (worse sleep) and watching technology between 3 and 5 h (t = 2.01, p = 0.045), and mothers' unemployment status (t = 2.468, p = 0.014). Conclusion: In conclusion, technology use is associated with a negative impact on children sleep and behavior. Owning a digital device, using tablets, screen viewing for more than 3-5 h, and watching movies were significantly associated with negative child's behavior and sleep.
RESUMEN
OBJECTIVES: The objective of this study was to evaluate the prevalence of medically resistant epilepsy (MRE) in our hospital and to compare the prevalence with that in other populations. METHODS: We retrospectively analyzed the data of patients who visited the epilepsy clinics at King Fahd University Hospital, Al-Khobar, Saudi Arabia between January 2017 and December 2018. This study included patients aged ≥14 years who had at least 2 unprovoked seizures 24 h apart. Patients who had provoked seizure(s), paroxysmal events, or syncope or had incomplete medical records were excluded. The definition and classification of the International League Against Epilepsy were used. Moreover, we searched the En-glish literature using PubMed and Google Scholar to compare the prevalence of MRE between our population and other populations. RESULTS: In total, 1,151 patients were screened, and 751 patients were included in the final analysis. Of the 751 patients, 229 (male: 56.3%, female: 43.7%; mean age: 32.07 years, and standard deviation, 12.2 years) had MRE, with a cumulative prevalence of 30%. The etiology was as follows: unknown, 63.3% (n = 145); structural, 31.9% (n = 73); genetic, 3.1% (n = 7); and infectious, 1.7% (n = 4). None of the patients had metabolic or immune-related etiologies. CONCLUSION: The prevalence of MRE in our population (30%) is close to that in other populations (30-36.5%). Early identification of such patients is crucial to improve their management.

OBJECTIVES: To identify epilepsy triggers prevalent in Saudi Arabia with a view to seizure prevention or achieving a reduction in their frequency. METHODS: This is part of a cross-sectional study carried out in 2020 in a Saudi population in the Kingdom of Saudi Arabia (KSA). We used an online questionnaire to evaluate the most common seizure trigger factors. RESULTS: A total of 546 Saudi patients with epilepsy participated in the study, of which 289 (53%) were women. Of them, 263 (48.1%) had no seizure in the previous 3 months. One hundred and thirty-six (25%) had a family member with epilepsy. The most-reported trigger factor was sleep deprivation reported by 285 (52%), followed by stress 225 (41%), missed medication 210 (38.5%), anxiety 209 (38.3%), and fatigue 184 (33.7%). Conclusions: Sleep deprivation is the most reported trigger factor for seizures in the KSA, followed by stress, followed by missed medication.
