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.

OBJECTIVE: To describe the prevalence, knowledge and attitudes about complementary and alternative medicine (CAM) use and the proportion that seek advice from their physician about CAM use. METHODS: This cross-sectional observational study was performed in multiple sclerosis (MS) clinic of King Fahd Hospital of Universityin Alkhobar, Kingdom of Saudi Arabia from January-June 2017. A total of 133 patients have completed the survey. RESULTS: The mean age of patients was 32.3+/-7.6 years and 84 (63.2%) were female. Approximately 83.5% of the patients reported the use of CAM. Among all the reported forms of CAM, vitamins were the most prevalent form, followed by cupping, special prayers and meditation. The majority of patients (62%) obtained knowledge of CAM through social media. A significant number of patients (75.6%) did not disclose the use of CAM to their physician. There was a trend for using CAM more in highly educated, older age, and female patients. The most commonly reported rationale to use CAM was overall improvement in health status. CONCLUSION: The use of CAM among Saudi patients with MS is highly prevalent, without disclosure of its use to physicians. These factors should be taken into account in the doctor-patient consultation to avoid adverse events.

OBJECTIVE: To evaluate new onset epilepsy characteristics, etiology, radiological and electroencephalographic features and to document treatment response in the elderly. METHODS: This was a retrospective study carried out in King Fahd Medical City, Riyadh, Kingdom of Saudi Arabia, from 2010 to 2013. Medical records were searched to recruit patients. Hundred and nineteen patients were enrolled who fulfill the inclusion criteria. Clinical data with respect to seizure semiology, etiology, electroencephalographic findings, radiological findings, co-morbidities, and anti-epileptic drug (AED) therapy were assessed. RESULTS: Cerebrovascular disease was the most common etiology, followed by occult cerebrovascular disease (oCVD). Focal onset seizures were the most common clinical presentation in this group of cohort. Electroencephalogram (EEG) showed generalized slowing in majority of patients (45.5%), with 21.8% interictal epileptiform activity. Patients required lower doses of AEDs to control seizures, gain better seizure control. Common co-morbidities were hypertension and diabetes mellitus. CONCLUSION: Patients presenting with LOE, should have search for any other cerebrovascular risk factors. Further research is needed to determine the prevalence of oCVD in LOE, and to investigate whether addressing cerebrovascular risk factors in this cohort of patients can reduce the incidence of stroke.

Posterior reversible encephalopathy syndrome (PRES) is a neuroradiological syndrome, clinically present by impaired consciousness, headache, visual disturbances, and seizures, and radiologically brain edema. Cases of PRES induced by blood transfusion are rarely documented. We report this case to increase the awareness of treating physicians for the possible complications of rapid blood transfusion. A 29-year-old man presented with polytrauma and was in hemorrhagic shock. He was transfused with multiple transfusions. Later, he was found to have quadriplegia with minimal movement of fingers in the left hand. His computed tomography showed cerebral edema in multiple cerebral regions. We propose that the etiology in this case is that rapid blood transfusion induced acute rise in hemoglobin which led to PRES. The influences of blood transfusion on blood flow, blood viscosity, and endothelial dysfunction lead to blood-brain barrier dysfunction, which can result in PRES.
RESUMEN
OBJECTIVE: As stroke is still considered a significant cause of mortality and morbidity, it is crucial to find the factors affecting the outcome in these patients. We aimed to interpret the various clinical and investigational parameters and establish their association with the outcome in stroke patients. MATERIALS AND METHODS: This is a retrospective, cross-sectional study, conducted in the Department of Neurology between June 2019 to November 2021. The study involved the review and analysis of medical records pertaining to 264 patients, admitted with the diagnosis of stroke. Various clinical, radiological, and electroencephalographic (EEG) patterns in stroke patients were analyzed and their association with outcome was established. The association between the studied variables was performed by the logistic regression (LR) and presented as odds ratio (OR) and 95% confidence interval (CI). RESULTS: The study sample consisted of 264 patients. Males comprised 165 (62.5%) with the mean participant age of 57.17 ± 18.7 3 years (range: 18-94). Patients younger than 50 years had a better likelihood of a good outcome in comparison to patients older than 50. The admission location was the most significant factor in predicting the outcome (P = 0.00) in favor of inpatient department and outpatient department (OPD), in contrast to patients admitted directly to intensive care unit (ICU). Normal EEG was associated with good outcome (P = 0.04; OR, 3.3; CI, 1.01-10.88) even after adjustment of the confounders, whereas patients having marked EEG slowing had a poor outcome (P = 0.05; OR, 2.4; CI, 0.65-8.79). Among the clinical parameters, hemiparesis (P = 0.03), trauma (P = 0.01), generalized tonic-clonic seizures (GTC) (P = 0.00), and National Institutes of Health Stroke Scale of more than 4 were more likely associated with a poor outcome as well as the presence of intracranial hemorrhage (ICH) or infarction in the cortical and cortical/subcortical locations were associated with poor outcomes. After adjustment of confounders, the factors found to have prognostic significance in favor of good outcomes were inpatients or OPD referrals and normal EEG while direct admission to ICU, marked slowing on EEG, and presence of ICH were found to be associated with poor outcome. CONCLUSION: Certain patterns are predictive of good or worse outcomes in stroke patients. Early identification of these factors can lead to early intervention, which in turn might help in a better outcome. The results of the study, therefore, have some prognostic significance.
Résumé Objectif:Étant donné que l'AVC est toujours considéré comme une cause importante de mortalité et de morbidité, il est crucial de trouver les facteurs qui influent sur le résultat dansces patients. Notre objectif était d'interpréter les différents paramètres cliniques et expérimentaux et d'établir leur association avec le résultat de l'AVC patient.Matériaux et méthodes:Il s'agit d'une étude transversale rétrospective, réalisée au Département de neurologie à partir de juin 2019 à novembre 2021 et comprenait l'examen et l'analyse des dossiers médicaux de 264 patients admis avec un diagnostic d'AVC. Divers profils cliniques, radiologiques et électroencéphalographiques (EEG) chez les patients victimes d'un AVC ont été analysés et leur association avec les résultats a été créé. L'association entre les variables étudiées a été réalisée par régression logistique (LR) et présentée sous forme de rapport de cotes (RC) et intervalle de confiance (IC) à 95 %.Résultats:L'échantillon de l'étude comprenait 264 patients. Les hommes représentaient 165 (62,5 %) avec le participant moyen âge de 57,17 ± 18,7 3 ans (intervalle : 1894). Les patients de moins de 50 ans avaient une meilleure probabilité d'obtenir un bon résultat par rapport aux patients Le lieu d'admission était le facteur le plus important dans la prédiction du résultat (P = 0,00) en faveur du service d'hospitalisation et le service ambulatoire (OPD), contrairement aux patients admis directement à l'unité de soins intensifs (USI). Un EEG normal était associé à un bon résultat (P = 0,04; RC, 3,3; IC, 1,01-10,88) même après ajustement des facteurs de confusion, alors que les patients ayant marqué un ralentissement de l'EEG avaient un faible plus de 50 ans. résultat (P = 0,05; RC, 2,4; IC, 0,65-8,79). Parmi les paramètres cliniques, hémiparésie (P = 0,03), traumatisme (P = 0,01), tonico-clonique généralisé les convulsions (GTC) (P = 0,00) et l'échelle des accidents vasculaires cérébraux des National Institutes of Health de plus de 4 étaient plus susceptibles d'être associés à un mauvais résultat comme ainsi que la présence d'hémorragie intracrânienne (ICH) ou d'infarctus dans les emplacements corticaux et corticaux/sous-corticaux étaient associés à une Résultats. Après ajustement des facteurs de confusion, les facteurs ayant une signification pronostique en faveur de bons résultats étaient les patients hospitalisés ou l'OPD les renvois et l'EEG normal pendant l'admission directe à l'USI, le ralentissement marqué de l'EEG et la présence de PCI se sont avérés être associés à une mauvaise résultat.Conclusion:Certains modèles sont prédictifs de résultats bons ou pires chez les patients victimes d'un AVC. L'identification précoce de ces facteurs peut conduire à une intervention précoce, ce qui pourrait à son tour aider à obtenir de meilleurs résultats. Les résultats de l'étude ont donc une certaine signification pronostique.
RESUMEN
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 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.

BACKGROUND: Literature on the frequency, response to treatment, and outcomes of acute ischemic stroke (AIS) due to intracranial atherostenosis (ICAS)-related intracranial large artery occlusion (ILAO) from Saudi Arabia is scarce. The aim of this study was to identify the percentage, describe the characteristics, and observe the treatment response in patients with AIS attributed to ICAS-related ILAO. MATERIALS AND METHODS: This cross-sectional study included all adult patients from 2017-2021 who fulfilled the inclusion criteria for the diagnosis of ICAS-related AIS. Patients were dichotomized based on ILAO. Mortality and functional outcomes (FOCs) based on 90 days' dependence level were compared between the two groups. The association between ILAO and other variables was assessed using the Chi-squared test, odds ratios (OR), and 95% confidence interval (CI). RESULTS: ILAO was found in 38.7% of patients with ICAS-related AIS. Men comprised three-fourths of the cohort and were more frequent in the ILAO group. Smoking was associated with increased (P = 0.04) likelihood of ILAO. Patients with ILAO had more severe strokes (P ≤ 0.001) than patients without. Middle cerebral artery was the most common occluded vessel (52%). Functional dependence (P = 0.003, OR = 2.87, CI = 1.42-5.77), malignant transformation (P = 0.001, OR = 8.0, CI = 1.82-35.9), and mortality (P ≤ 0.001, OR = 7.67, CI = 2.40-24.5) were significantly higher among ILAO group. Patients with ILAO with unfavorable FOC were older than those who achieved better FOC (P ≤ 0.001). Thrombolysis (P = 0.02, OR = 2.50, CI = 1.15-5.41) and mechanical thrombectomy (MT) improved FOC in patients with ILAO (P = 0.04, OR = 2.33, CI = 1.10-4.92). CONCLUSION: ILAO is common in patients with ICAS-related AIS. Timely hyperacute stroke treatment can help improve the FOC of otherwise disabling stroke due to ILAO. Raising awareness of the community about stroke is needed, so that a higher number of patients can arrive at hospital within the golden hours. Further data from the region are required to recognize the efficacy of MT in ICAS-related ILAO.
RESUMEN
Vertebral artery dissection (VAD) is a common cause of stroke in middle-aged individuals. Patients with VAD usually describe a trivial minor neck trauma preceding the event. Such traumas may be associated with spinal manipulation or sudden movements of the neck. Our case is a 43-year-old lady who presented with a history of sudden-onset dizziness, dysarthria, nausea/vomiting, tinnitus, and imbalance. Two days prior to her presentation, she experienced a new-onset moderate to severe intensity headache along with neck pain. The patient mentioned a first-time use of a home massage device three weeks prior to headache onset. After investigations, the patient was diagnosed with VAD, and treatment was initiated. She was discharged in stable condition. With the recent increased popularity of home massage devices, we report this case to raise awareness about the safe use of massage devices in order to prevent the occurrence of such injuries and complications.
RESUMEN
Objective: This study aimed to investigate the effect of the glycated hemoglobin A1c (HbA1c) level on the functional outcome (FOC) in patients with intracranial large artery atherosclerotic disease (ICLAD)-related acute ischemic stroke (AIS). Methods: This retrospective study enrolled patients with ICLAD-related AIS who were admitted to King Fahd University Hospital between January 2017 and September 2021. Patients were divided into two groups based on the optimal cutoff HbA1c level determined using receiver operating characteristic curve analysis-those with HbA1c ≤6.9% and those with HbA1c >6.9%. Demographic and other clinical characteristics were compared between the two groups using chi-square tests. The association between HbA1c and 90-day FOC was assessed using the chi-square test and odds ratios (ORs). Multivariate analysis was performed to adjust for confounding factors. Results: A total of 140 patients were included in the analysis. A significant association was observed between the HbA1c level and FOC. Compared to patients with HbA1c ≤6.9%, patients with HbA1c >6.9% were more likely to have an unfavorable FOC [p = <0.001, OR = 2.05, 95% confidence interval (CI) = 1.33-3.14]. The association between HbA1c >6.9% and unfavorable FOC was sustained even after adjusting for confounding factors (p = 0.008) and atherosclerosis risk factors (p = 0.01). HbA1c >6.9% was also associated with higher ORs for in-hospital complications (p = 0.06, OR = 1.34, 95% CI = 1.02-1.77) and mortality (p = 0.07, OR = 1.42, 95% CI = 1.06-1.92) although these associations did not attain significant p-values. Conclusion: HbA1c >6.9% was significantly associated with unfavorable FOC in ICLAD-related AIS. However, further studies with larger sample sizes are required to verify whether HbA1c is an independent predictor of poor FOC. Nevertheless, targeting HbA1c <7% should be the goal of physicians when managing patients at high risk of ICLAD.
RESUMEN
Background: Studying mental disorders in children is significantly important due to the huge suffering of educational and psychosocial impairments in adult life. Attention-deficit/hyperactivity disorder (ADHD) is considered the most common mental disorder in children, especially in early school-aged children. It manifests in about 8%-12% of children in the world. In Saudi Arabia, it affects 4%-12% of children. Objective: The study aimed to count the number of undiagnosed ADHD cases and the associated risk factors in Eastern Province in Kingdom of Saudi Arabia (KSA). Methods: A cross-sectional study was performed among girls' and boys' children aged 6-10 years old in Eastern Province in KSA with a random selection of parents. Sample size is equal to 1658. The assessment was done by an online questionnaire filled it by parents using Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnostic criteria and Connor's scale of ADHD excluding any developmental or mental disorder at the beginning of the questionnaire. Results: After excluding the participants who were diagnosed with behavioral and growth developmental disorder, the remaining 1430 have been screened for ADHD based on Connor's scale. 185 of a child out of 1430 were suggested to have ADHD, of which 10 out of them show the signs of ADHD, 76 of them have moderately severe ADHD, and 99 out of them have atypical or severe ADHD based on Connor's scale of ADHD. The study shows that there is a significant relationship between the positive screening of ADHD and gender males (71.35%), females (28.64%), family history (20.5%), nervous system diseases (4.32%), brain damage from trauma (9.72%), smoking habit of the mother (8.64%), smoking during pregnancy (3.78%), mother exposure to second-hand smoking (42.16%), child exposure to a toxic substance like lead during the early life (1.62%), and the preterm labor (15.13%). However, the study shows there is no significant relationship between the positive screening of ADHD with age, drinking alcohol, and central nervous system infection. Conclusion: The prevalence of undiagnosed ADHD is slightly high. Also, it has many causes of ADHD including gender, smoking, parental psychiatric disorders, and obstetric and pregnancy problems.
Résumé Background: L'étude des troubles mentaux chez les enfants est d'une importance considérable en raison des souffrances liées aux difficultés scolaires et psychosociales qui perdurent à l'âge adulte. Le trouble du déficit de l'attention avec hyperactivité (TDAH) est considéré comme le trouble mental le plus courant chez les enfants, notamment chez les enfants d'âge scolaire précoce. Il se manifeste chez environ 8% à 12% des enfants dans le monde. En Arabie saoudite, il touche entre 4% et 12% des enfants. Objective: L'étude visait à dénombrer le nombre de cas de TDAH non diagnostiqués et les facteurs de risque associés dans la province orientale du Royaume d'Arabie saoudite (KSA). Methods: Une étude transversale a été réalisée auprès d'enfants de filles et de garçons âgés de 6 à 10 ans dans la province orientale de l'Arabie saoudite, en utilisant une sélection aléatoire des parents. La taille de l'échantillon est égale à 1658. L'évaluation a été réalisée à l'aide d'un questionnaire en ligne rempli par les parents, en utilisant les critères diagnostiques du Manuel diagnostique et statistique des troubles mentaux, cinquième édition, ainsi que l'échelle de Connor pour le TDAH, en excluant tout trouble du développement ou trouble mental au début du questionnaire. Résultats: Après exclusion des participants ayant été diagnostiqués avec un trouble du comportement et du développement, les 1430 restants ont été dépistés pour le TDAH à l'aide de l'échelle de Connor. Parmi ces enfants, 185 ont été suggérés d'avoir un TDAH, dont 10 présentent des signes de TDAH, 76 présentent un TDAH modérément sévère et 99 présentent un TDAH atypique ou sévère selon l'échelle de Connor. L'étude révèle qu'il existe une relation significative entre le dépistage positif du TDAH et le genre masculin (71,35 %), féminin (28,64 %), les antécédents familiaux (20,5 %), les maladies du système nerveux (4,32 %), les lésions cérébrales suite à un traumatisme (9,72 %), la consommation de tabac par la mère (8,64 %), la consommation de tabac pendant la grossesse (3,78 %), l'exposition de la mère à la fumée secondaire (42,16 %), l'exposition de l'enfant à une substance toxique comme le plomb pendant la petite enfance (1,62 %) et le travail prématuré (15,13 %). Cependant, l'étude montre qu'il n'existe aucune relation significative entre le dépistage positif du TDAH et l'âge, la consommation d'alcool et les infections du système nerveux central. Conclusion: La prévalence du TDAH non diagnostiqué est légèrement élevée. De plus, il existe de nombreuses causes du TDAH, dont le genre, le tabagisme, les troubles psychiatriques des parents, ainsi que les problèmes obstétriques et durant la grossesse. Mots-clés: Attention, trouble du déficit de l'attention/hyperactivité, Province orientale, hyperactivité, Royaume d'Arabie saoudite.

Hypermotor seizures (HMS) can include different forms of hypermotor behaviour due to various mechanisms associated with generation of ictal automatisms. Despite the varied location of seizure onset, similar semiologic features during seizures may exist. Ictal single-photon emission tomography (SPECT) apparently reflects not only the origin of epileptic discharge but also the spread to adjacent cortical areas. Taking this benefit of SPECT studies into account, preoperative SPECT results from 13 patients with HMS who underwent epilepsy surgery were analysed. The radioisotope 99mTc-ECD was injected in all patients within five seconds after seizure onset. Group analysis was performed with statistical parametric mapping (SPM) of paired ictal-interictal SPECTs in order to identify regions of significant ictal hyperperfusion. Hyperperfused regions with a corrected cluster-level significance p-value of < 0.002 were considered significant. Seizure onset at implanted subdural electrodes was defined as the epileptic focus in 12 of 13 patients. Two patterns were recognized: HMS-1 with marked agitation and HMS-2 with mild agitation. Ictal hyperperfusion images revealed significant hyperperfusion in the anterior cingulate cortex, orbito-frontal gyrus, lentiform nucleus, midbrain and pons. These hyperperfused areas represent the symptomatogenic zone which was different from the epileptogenic zone, as confirmed by the favourable outcomes after surgical resection. The present findings suggest that a network, including frontal and possibly extrafrontal brainstem and limbic structures, is involved in the genesis of the complex epileptic manifestations of HMS. Moreover, ictal SPECT analysed by SPM is a useful method for studying the neural networks of different types of seizures.

Objective: To compare cardiovascular risk factors in patients with epilepsy with those of non-epileptic neurologic patients to determine their association with antiepileptic drug therapy.Methods: This observational study with a cross-sectional design was performed in a tertiary care hospital in the Eastern Province of Saudi Arabia from January to December 2018. A total of 110 patients with epilepsy were included in the study, along with 46 age- and sex-matched non-epileptic controls (approximate ratio of 2:1). Blood pressure reading (BP), anthropometric measurements, fasting blood sugar levels, and fasting lipid profiles were performed for all subjects.Results: Raised non-high-density lipid cholesterol (nHDLC) was the most common cardiovascular risk in epileptic patients, with a frequency of 51% compared to 30.4% in controls (P = .019). Epileptic patients who were male (58.3%, 28/48, P = .012) and those aged < 35 years (47.3%, 26/55, P = .036) were more likely to have high nHDLC. Obesity was also common in epileptic patients with frequency of 49.1% (n = 54) versus 30.4% (n = 14) in controls (P = .032). Metabolic syndrome was present in 26.3% of epileptic patients versus 23.9% of controls (P = .749). Among the epileptic patients, of those with high nHDLC, 85.7% had satisfactory seizure control (P = .019).Conclusions: Raised nHDLC and obesity but not metabolic syndrome appear to be highly prevalent in epileptic patients compared to those without epilepsy. Antiepileptic drugs alone may not play a role in developing high lipid levels. More studies are needed to determine the causes of higher risk factor profile in epileptic patients and their relationship with seizure control.

Objective: Wake-up stroke (WUS) comprises a significant proportion of ischemic strokes. However, due to unclear onset, these patients are often not considered for reperfusion therapy. The objective of this study was to investigate the clinical and imaging differences between WUS patients and those with clear-onset stroke, documenting any sex, age, or risk factor predilection for WUS.Methods: This prospective observational cohort study used an ongoing stroke registry to identify patients with acute ischemic stroke admitted to a hospital in Saudi Arabia within 5 days of symptom onset from April 2018 to March 2020. Patients were classified into 2 groups: WUS and clear-onset stroke.Results: Among 645 patients, 448 met the criteria for acute ischemic stroke and were included in the study. WUS was identified in 112 (25%) patients. There were no differences in sex or median age between the 2 groups. Diabetes mellitus, hypertension, and dyslipidemia were higher in the WUS group, while atrial fibrillation, history of stroke and epilepsy were higher in the clear-onset stroke group. Bihemispheric stroke was higher in the clear-onset stroke group than in the WUS group (6.0% vs 2.7%).Conclusions: Only minor dissimilarities between clinical and radiologic features of WUS and clear-onset stroke were found. Circadian patterns of stroke onset were observed in both groups. Stroke was more likely to occur during waking than during sleep, and a diurnal pattern of common occurrence during the morning was documented. Recognition of the acceptable timeframe for acute reperfusion therapy in unwitnessed strokes is crucial so that thrombolytic treatment can be started for these patients.

OBJECTIVE: The objective of this study was to determine the frequency and clinical correlates of different electroencephalographic patterns and their association with clinical outcomes in critically ill patients. SUBJECTS AND METHODS: This retrospective cross-sectional study was performed in the Neurology Department of King Fahd Hospital of the University, Kingdom of Saudi Arabia and involved a review and analysis of medical records pertaining to 179 intensive care unit patients who underwent electroencephalography (EEG) in the June to November 2018 period. RESULTS: Among the different etiologies, presence of spike and wave or sharp wave (SWs) was associated with encephalitis (P = .01) and large artery stroke (P = .01), whereas markedly attenuated EEG activity (p = .04) and burst suppression (P = .01) were associated with large artery stroke and hypoxic ischemic encephalopathy (HIE), respectively. Generalized theta activity (P = .01) was significantly found in patients of septic encephalopathy, while generalized delta activity (P = .02) and asymmetrical background (P = .04) were significantly associated with traumatic brain injury. Presence of periodic discharges in EEG was significantly associated with more adverse clinical outcomes (P = .001), whereas rhythmic delta activity (RDA) (P = .03), persistent focal slow wave activity (P = .01), and asymmetric background (P = .002) were found in patients who were discharged from hospital with sequelae of current illness. CONCLUSION: Certain EEG patterns are associated with particular underlying etiologies like SWs for encephalitis, markedly attenuated EEG activity and burst suppression with large artery stroke and HIE, respectively. Whereas few EEG patterns, including periodic discharges, RDA, persistent focal slow wave activity have some prognostic value in critically ill patients. However, they cannot be used as markers for prognostic assessment of patients without considering other clinical and diagnostic variables. Further larger prospective studies with continuous EEG monitoring with control of confounding factors are needed.

Objective: To compare the safety and efficacy of conventional anticoagulants with new oral anticoagulants (NOACs) for management of cerebral venous sinus thrombosis (CVST).Methods: This was a retrospective, prospective cohort study of patients who presented with CVST to a tertiary stroke center in the Middle East from January 2012 to October 2019. Patients with a diagnosis of CVST were identified, and data were analyzed for demographic characteristics. Specific consideration was given to compare the efficacy and safety of different anticoagulation treatments.Results: A total of 36 patients were included in the final analysis, with 15 (41%) men and 21 (59%) women and a male to female ratio of 1:1.4. Most of the patients (n = 22, 61%) were Saudi. Their ages ranged between 15 and 82 years (mean ± SD age of 34.22 ± 13.16 years). Headache was the most common feature, present in 22 (61%) of the patients, followed by unilateral weakness in 15 (41%) and cranial nerve palsies in 11 (30%). The most common etiology was prothrombotic state (both hereditary and acquired thrombophilia: n = 16, 45%). Other etiologies were postpartum state/oral contraceptive pill usage in 7 (19%), infections in 7 (19%), and trauma in 3 (8%). Most of the patients (n = 24, 67%) still received conventional anticoagulation (warfarin/low molecular weight heparin), but 9 (25%) of the patients consented to start NOACs. Efficacy (as measured by clinical improvement plus rate of recanalization of previously thrombosed venous sinuses) showed no statistically significant difference, although it proved to be better tolerated, as none of the patients stopped the treatment due to adverse events and risk of major bleeding was significantly low in the NOAC group. Nine patients in the warfarin group stopped medication, while none in the NOAC group did so (P = .034).Conclusion: NOACs were found to be at least as good as conventional anticoagulation for the management of CVST. However, efficacy was almost similar, a finding that is consistent with most of the published case series and the few recently published prospective studies. Larger prospective and population-based studies are needed to clarify our preliminary results.

Hashimoto's encephalopathy (HE) is an uncommon neurological disorder of unknown etiology, found in association with thyroid autoimmunity, mostly uncommon in males. The disease occurs primarily in the fifth decade of life and may occur in two forms; a sudden vasculitic type or a progressive subacute type associated with cognitive dysfunction, confusion, and memory loss. We report a case of a 51-year-old Sri Lankan gentleman with no comorbidities who was presented with one episode of the generalized tonic- clonic seizure (GTCs) followed by prolonged agitation and disorientation. His EEG showed generalized slowing while CT scan and MRI brain were unremarkable. CSF examination showed high protein level with normal cell count and glucose. Routine serologic examination showed very high thyroid-stimulating hormone (TSH) level, with significantly high antithyroid antibodies. He was diagnosed as a case of Hashimoto's encephalopathy and treated with a high dose of steroid and showed remarkable improvement.

BACKGROUND AND PURPOSE: Sex-related differences have been documented in risk factors distribution, etiologic subtypes, diagnostic evaluation, offered management, and outcome of patients with acute ischemic stroke (AIS) from all over the world. Nevertheless, studies from Saudi Arabia are lacking. This study aimed to investigate the influence of sex on distribution of risk factors and etiologic subtype of AIS in patients admitted to our hospital. MATERIALS AND METHODS: Record of patients admitted to King Fahd Hospital of the University between 2010 and 2017 with ischemic stroke (IS) were reviewed. Base line characteristics, risk factors, and etiologic subtypes according to Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification were compared between men and women. RESULTS: Among 453 patients with IS, 300 (66.2%) were men and 153 (33.7%) were women. The mean age of all patients was 61.5 ± 14.5 years. Women were older than men (P = 0.00). Hypertension (P = 0.00), atrial fibrillation (P = 0.00), and past history of stroke (P = 0.03) were more frequent in women compared to men. Fewer carotid Doppler studies (47.1 vs. 68.3%, P = 0.00) and echocardiogram (75.1 vs. 83%, P = 0.01) were done in women as compared to men. Cardioembolic etiologic subtype (26.1 vs. 17.7%) was found more frequently, whereas small vessel occlusive (23.5 vs. 31%) and large artery disease less (10.5 vs. 16.3%) frequently in women. CONCLUSION: Significant sex-related differences were found in risk factors and subtypes of AIS in our cohort of patients. Findings of our study are in general comparable with studies from all over the world.

OBJECTIVE: To identify timing for initiation of anticoagulation therapy in acute ischemic stroke (AIS) with non-valvular AF as regards safety and efficacy by detecting the rate of intracranial haemorrhage (ICH) and recurrent ischemic symptoms (RIS) during follow-up. METHODS: This is a prospective observational cohort study conducted at King Fahd Hospital of the University including 120 patients with AIS/TIAs from July 2016 till July 2018. We compared patients who received anticoagulants 1-6 days (Group I (45.83%), 7-14 days, Group II (35%), and > 14 days after the ischemic event (Group III (19.17%). Follow-up was at least 3 months and included identifying ICH or RIS. RESULT: ICH has occurred in 26.67% (n = 32) patients with a highly statistically significant association with time of treatment (P-value = .01) being higher in group I (n = 17) compared to only 1 case in group III. Subgroup analyses on the ICH patients (n = 32) has revealed statistical significant association with higher NIHSS score (P = .001). Also, the type of anticoagulants used between three groups pointed to an association existence (p = .02), however, the direction of this association cannot be determined. There was no statistical significant association between RIS (occurred in 4.16% (n = 5) with time of treatment (P = .754). Functional outcome at 3-6 months measured by mRS did not differ between 3 groups (worst mRS in group I). CONCLUSION: Early initiation of anticoagulation after stroke, especially in cases of large infarction, is associated with significant risk of ICH. This risk is highest with warfarin and lowest with DOAC.
