Quality of life predictors among Moroccan adults with epilepsy.

PURPOSE: This study aimed to determine the factors associated with quality of life (QOL) in adult patients living with epilepsy in Morocco. METHODS: 110 patients with epilepsy aging 18 years old were interviewed using the standard and validated Moroccan version of the Quality of Life in Epilepsy inventory with 31 items (QOLIE-31). Descriptive statistics, one-way ANOVA, and multivariate regression were used for data analysis. RESULTS: The mean age of the patients was 35.70 years old (standard deviation (SD)12.2). The mean total score of QOLIE-31 was 43.6±10.2. The highest mean±SD score was the medication effects subscale 52.3±12.1, and the lowest was the overall quality of life subscale 39.2±13.2. Patients with no seizure episode during the last month had a better mean total score of QOLIE-31 (47.6±10.5) than the study participants having a seizure in the last month (40.6±8.9, p≤0.001). These data supported that presence of seizure in the past 4 weeks (ß=4.626, CI95 % 1.123; 8.130), memory disorders (ß=10.025, IC 95 % 2.811; 17.239), seizure trigger factors such as forgetting to take antiepileptic drugs (AEDs) (ß=5.205, IC 95 % 1.769; 8.641), personal problems (ß=4.957, IC 95 % 0.604; 9.310), low monthly income (<2000MAD, 194.94$: ß= -9.937, IC 95 % -18.536; -1.338), (2000-5000MAD, 194.94$- 487.35$: ß= -24.804, IC 95 % -43.171; -6.437), and employment (ß= -4.291, IC 95 % -7.976; -0.605) were the factors associated with QOL. SIGNIFICANCE: The overall QOL of patients with epilepsy was low. This study showed that the presence of seizures, memory disorders, monthly income, trigger factors, and employment status were QOL predictors for epileptic patients.

The Scale Assessment of Executive Functions-Adult (SAEF-A): Construction of a valid ecological instrument.

OBJECTIVES: This study aims to validate the SAEF-A (Scale Assessment Of Executive Functions-Adult) test, a new instrument for measuring executive functions in adults. MATERIALS AND METHODS: The study participants are residents of Fez-Meknes over 18 years old. Two groups were enrolled: people with epilepsy and a healthy group. We constructed the tests in all three Moroccan languages: Darija, Tamazight, and Arabic. We validated the SAEF-A test according to Bernaud's instructions compared to the BRIEF-A test. RESULTS: The Alpha Cronbach and Split Half were 92% and 88%, respectively. Exploratory research results highlight five facets of perceived value. Significant convergent validation existed between the BRIEF-A subscales and the SAEF-A scale. The results show that the people with epilepsy sample can be discriminated from the healthy ones in all dimensions, except planning, with a minor difference. CONCLUSIONS: The results provide good reliability and validity for the SAEF-A. It will be helpful in studies of Moroccan adults and other people.

Prevalence of epilepsy in Morocco: A population-based study.

OBJECTIVE: In Morocco, there was a lack of data related to the epidemiology of epilepsy. This data serves as a useful basis for the development of any national intervention or action program against epilepsy in Morocco. Through this study, we aimed to estimate the active and lifetime prevalence of epilepsy in Morocco. METHODS: We collected data from eight out of 12 Moroccan regions in two steps: In the screening step, we first used a nationwide telephone diagnosis questionnaire and in the second stage, a team of physicians under the direction of an epileptologist conducted a confirmative survey for suspected cases. We fixed the confidence interval at α = 5% and the precision at 0.02. RESULTS: Up to 3184 responded positively to our invitation to participate in this study and were able to answer the questions of the first diagnostic questionnaire. In the diagnostic phase, physicians in neurology reinterviewed all 86 suspected cases using a confirmative diagnosis questionnaire, and 63 persons were confirmed as having lifetime epilepsy and 56 with active epilepsy. The mean age (Mean ± SD) of persons with epilepsy was 35.53 years (±21.36). The prevalence of lifetime and active epilepsy were 19.8 (19.6-20.0) and 17.6 (17.5-17.8) per 1000 (95% confidence interval), respectively. SIGNIFICANCE: This is the first study to estimate the active and lifetime prevalence of epilepsy in Morocco according to the international recommendations of the ILAE. The prevalence of lifetime and active epilepsy were 19.8 (15-24.6) and 17.6 (13.3-22.8) per 1000, respectively. We included both children and elderly subjects. The rates of active and lifetime population epilepsy prevalence in Morocco ranged between Asian and sub-Saharan Africa low- and middle-income countries.

Working memory training in autism: Near and far transfer.

INTRODUCTION: The autistic population is expanding. It is generally recognized that executive function deficits (EFs) are at the core of this disorder. Working memory (WM) is considered a critical element in executive functioning. WM training is regarded as a promising new therapy that can improve EFs and reduce symptoms of autism by targeting WM through repetitive exercises. AIM: To investigate the impact of WM training on WM, cognitive flexibility, planning, and clinical symptoms. Also, to examine whether age influences the remediation effects. METHODS: Only one group of 20 verbal autistic participants aged 6 to 21 years was included. They received 40 training sessions. The program used is called "Cogmed". Neuropsychological measures were administered before and after the intervention to assess the three EFs. The Social Communication Questionnaire (SCQ) was exploited to evaluate its effects on clinical symptoms. RESULTS: Only 17 participants have completed the training. They showed significant and large improvements in WM subtests (p<0.01, η^2>0.06), cognitive flexibility (p<0.05, η^2>0.06), planning (p<0.01, η^2 >0.06), and symptoms (p<0.01, η^2 >0.06). Also, the ANOVA test revealed that the age and the intervention effects are not correlated in our sample (p >0.05). CONCLUSION: WM training influences EFs positively in autism and reduces the severity of its clinical characteristics. Thus, it's an effective therapy that can be added to the management of this disorder.

The Moroccan MoCA test: Translation, cultural adaptation, and validation.

PURPOSE: Dementia includes all the symptoms associated with declining mental and cognitive skills, resulting in an inability to perform daily activities. OBJECTIVES: We aimed to translate and adapt the Montréal Cognitive Assessment (MoCA) test into the Moroccan cultural context. We compared the sensitivity and specificity between MoCA and Mini-Mental State of Folstein (MMS) in the screening of dementia. MATERIALS AND METHODS: The participants in this study were residents in the Fez-Meknes region and over 50 years old. We performed translation and adaptation of the English MoCA 8.1 version into all Moroccan languages: Darija, Tamazight in its three variants (Tachelhit, Tarifit, Atlas Tamazight), and Arabic. We validated Moroccan MoCA according to the Beaton et al. instructions. RESULTS: The sensitivity, specificity, and alpha Cronbach of the MoCA test were 88.5, 93.8%, and 0.87, while they were 90.2, 90.8%, and 0.79 for the MMS test. CONCLUSION: The Moroccan MoCA test had high sensitivity, specificity, and internal reliability compared to the MMS test. The availability of the MoCA in the Moroccan language will be helpful in the screening of dementia and research studies in Morocco and other countries.

Moroccan Arabic version of the Quality of Life Inventory in Epilepsy (QOLIE-31): translation, cultural adaptation and psychometric validation.

BACKGROUND: There is currently a growing concern to conduct health-related quality of life (HRQOL) studies among people with epilepsy in low- and middle-income countries, as most data have been derived from high-income countries in North America and Europe. AIMS: To translate, adapt and validate the Moroccan Arabic version of the QOL Inventory in Epilepsy-31 (MA-QOLIE-31) to evaluate HRQOL predictors in the Moroccan population with epilepsy. METHODS: Adaptation and validation of QOLIE-31 were performed in July 2018 among 118 patients with epilepsy in the Fez-Meknes region. The test was translated, adapted and validated into Arabic according to the Streiner & Norman recommendations. Acceptability, reliability, central tendency and validity of the QOLIE-31 were assessed. RESULTS: The acceptability and reproducibility were satisfactory and the internal consistency was strong (Cronbach α = 0.993). The mean (standard deviation) global score of QOL in the MA-QOLIE-31 was 68 (22.16). The scores in the subscales were 51 (36.88) for seizures worry, 48.86 (25.44) for overall QOL, 45.60 (26.73) for well-being, 41.28 (25.37) for energy and fatigue, 47.55 (28.33) for cognitive function, 66.83 (39.49) for medication effects and 52.44 (30.26) for social functioning. CONCLUSIONS: The global score of QOL in Moroccan patients with epilepsy is similar to that in patients in low and middle- income countries. MA-QOLIE-31 will facilitate further studies in HRQOL in Morocco and Arabic-speaking countries.

Epilepsy in Morocco: Realities, pitfalls and prospects.

The World Health Organization (WHO) estimates that about 50 million people of all ages have epilepsy and nearly 85% of whom live in low- and middle-income (LMICs) countries. In Morocco, epilepsy is one of the major neurological health conditions, with an estimated prevalence of 1.1%. The management of patients is difficult due to multiple factors. The lack of neurologists whose number is currently 180, the uneven distribution of neurologists who are concentrated in large cities, 43% of whom are in Rabat and Casablanca alone; the low involvement of general practitioners in the management of epilepsy; the frequent consultation of traditional healers; and the low coverage of social security all contribute to the treatment gap. The management of epilepsy has advanced considerably since the early nineties. Several factors contributed to this progress: the increasing number of neurologists compared to previous years, the creation of well-equipped new academic centers, and small units of general neurology, in addition to the disuse of several antiepileptic drugs. However, much work remains to be done against the use of many forms of traditional practices and the low involvement of general practitioners in the management of epilepsy. This is the first study on epilepsy conducted in Morocco.

Brain knowledge and predictors of neuromyths among teachers in Morocco.

The objective of this study was to evaluate brain knowledge and the prevalence of neuromyths among teachers in Morocco. We aimed also predicting factors that may improve teachers' brain knowledge and widespread of neuromyths. An online questionnaire was sent to a large population of Moroccan teachers. The questionnaire contains 32 questions, 20 of them are designed to assess teachers' knowledge about the brain and the remaining 12 questions are neuromyths. The mean score of brain knowledge was (64.34% (SD = 27.9%)) and the mean score of neuromyths was (66.56% (SD= 25.73%)). Besides, 50% of teachers were unable to correctly answer seven out of the 20 brain knowledge questions. Moreover, half of the teachers believed in 9 out of the 12 neuromyths. Knowledge about the brain was the foremost predictor of neuromyths. The study disclosed a real lack of brain knowledge with a widespread of neuromyths among teachers in Morocco.

Sleep quality and mental health in the context of COVID-19 pandemic and lockdown in Morocco.

BACKGROUND: The lockdown of COVID-19 (Coronavirus Disease 2019) is associated with several stressful factors that can negatively affect peoples' sleep quality and mental health. OBJECTIVES: We conducted this study to evaluate sleep disorders and psychological impact associated with the spread of the COVID-19 and the lockdown on the Moroccan population. We also aimed to study the effects of respondents' beliefs and attitudes about sleep on sleep disorders, anxiety-related symptoms, and depressive symptoms. MATERIAL AND METHODS: We used a questionnaire enclosing respondents' sociodemographic information, five psychological and behavioral tests including Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16), Athens Insomnia Scale (AIS), Epworth Sleepiness Scale (ESS), Hamilton Anxiety Rating Scale (HARS) and Beck Depression Inventory (BDI) test. RESULTS: Our results highlighted widespread false beliefs about sleep and the prevalence of sleep disorders, anxiety, and depression-related symptoms within the Moroccan population. Nearly 82.3% of respondents revealed false beliefs about sleep. Furthermore, we confirmed a strong positive correlation between knowledge and attitudes about sleep and the prevalence of sleep disorders, anxiety, and depression-related symptoms. However, we found no significant difference in the prevalence of sleep and psychological disorders, between healthcare workers and other professions workers. CONCLUSION: Our study revealed a high prevalence of sleep disorders, anxiety, and depressive symptoms in the Moroccan population during the COVID-19 lockdown period. Moreover, false beliefs on sleep understanding were prevalent and were presenting a risk factor leading to sleep disorders, anxiety, and depressive symptoms.

Stroke Mimics: Experience of a Moroccan Stroke Unit.

BACKGROUND: Stroke mimic is a medical condition presenting with acute neurological deficit and simulate real stroke. The objective of this study was to evaluate the frequency and the various etiologies of stroke mimics in our center. METHODS: We retrospectively reviewed the Thrombolysis Alert registry and we studied the frequency and characteristics of patients with stroke mimic. RESULTS: Among 673 patients who were admitted to the emergency department within 4.5 hours for sudden focal neurological deficit suggestive of acute stroke, 105 patients (15.6 %) had a stroke mimic. The mean age of patients with mimics and brain strokes were 66.3 and 64.8, respectively. The mean Onset-to-door time was 136.82 minutes and the mean door-to-imaging time was 32.63 minutes in stroke mimics. Seizure (28.5%) was the most common diagnosis of stroke mimics followed by conversion disorder (25.7%). CONCLUSIONS: Stroke mimic is frequent and heterogeneous entity that can be difficult to identify. Fortunately, most previous studies show no harmful effects when using thrombolysis in a stroke mimic.

Awareness and attitudes toward persons with epilepsy among teachers: A Moroccan study.

PURPOSE: Many studies performed in Morocco showed an important lack of knowledge about epilepsy among persons with epilepsy and their families. The misconceptions about the disease are a source of suffering for both patients and their families and increase the costs of epilepsy care. We conducted this investigation for assessing the origins of misinterpretation of the disease in the Moroccan society. OBJECTIVES: The teachers' knowledge about epilepsy in the Fez-Meknes region in Morocco and their attitudes toward a person with epilepsy constitute the two major objectives of this study. We also assessed the impact of sociocultural parameters on Moroccan teachers' knowledge and attitudes toward a person with epilepsy. MATERIAL AND METHODS: The data collection was based on the "Attitudes Toward Persons with Epilepsy" (ATPE) test. RESULTS: The study showed a positive correlation between the level of teachers' knowledge of epilepsy and their attitudes toward a person with epilepsy. The results revealed the persistence of negative attitudes toward a person with epilepsy among teachers. The level of ATPE of teachers in Morocco was lower compared to high-middle income countries. CONCLUSION: There is still poor knowledge about epilepsy among teachers in Morocco. This unawareness is negatively affecting teachers' attitudes toward a person with epilepsy. Hence, we recommend integrating epilepsy in teaching and training programs of teachers in the Moroccan educational system.

Limbic encephalitis: Experience of a moroccan center.

OBJECTIVES: Histologically defined as an inflammation-degeneration of limbic structures, limbic encephalitis (LE) is a rare disease and often difficult to diagnose particularly in institutions with limited access to laboratory tests such as antineuronal antibodies or HSV-PCR, and functional imaging. We aimed to describe the demographic, clinical, paraclinical, and etiological features of LE, as well as its medium-term prognosis in Moroccan patients. MATERIALS AND METHODS: We collected retrospectively all patients diagnosed with LE in the Department of Neurology of the University Hospital Hassan II of Fez (Morocco) between September 2008 and December 2016. We analyzed their demographic features, clinical manifestations, magnetic resonance imaging and laboratory findings, etiologies, and medium-term prognoses. RESULTS: We included 22 men and 9 women aged 14-76 years (mean age: 45.8 years). In 64.5% of cases, the onset of symptoms was acute. The clinical manifestations included generalized status epilepticus (16.1%), confusional syndrome (29%), epileptic seizures (38.7%), psychiatric disorders (48.4%), and memory disorders (45.2%). The nonlimbic symptoms were nuchal stiffness (22.6%), headaches (9.7%), fever (61.3%), vesicular rash (3.2%), and language disorders (6.5%). The different etiologies found were herpes simplex virus (6.5%), syphilis (16.1%), tuberculosis (3.2%), varicella (3.2%), paraneoplastic autoimmune LE (22.6%), anti-NMDA-R LE (6.5%), and sarcoidosis (3.2%). We found 12 cases (38.7%) of LE without definite etiology and with an incomplete diagnostic workup. The medium-term clinical course includes a complete remission in 45.2% of cases and partial remission in 45.1% of cases. The different sequelae were temporal lobe epilepsy (9.7%), anterograde amnesia (16.1%), and severe cognitive impairment (19.4%). The mortality rate was 9.7% (3 patients). CONCLUSION: Our study shows a wide diversity of etiologies of LE in Morocco with essentially an acute mode of onset of symptoms.

Reliability of the Arabic Smartphone Addiction Scale and Smartphone Addiction Scale-Short Version in Two Different Moroccan Samples.

The extensive accessibility to smartphones in the last decade raises the concerns of addictive behavior patterns toward these technologies worldwide and in developing countries, and Arabic ones in particular. In an area of stigmatized behavior such as Internet and smartphone addiction, the hypothesis extends to whether there is a reliable instrument that can assess smartphone addiction. To our knowledge, no scale in Arabic language is available to assess maladaptive behavior associated with smartphone use. This study aims to assess the factorial validity and internal reliability of the Arabic Smartphone Addiction Scale (SAS) and Smartphone Addiction Scale-Short Version (SAS-SV) in a Moroccan surveyed population. Participants (N = 440 and N = 310) completed an online survey, including SAS, SAS-SV, and questions about sociodemographic status. Factor analysis results showed six factors with factor loading ranging from 0.25 to 0.99 for SAS. Reliability, based on Cronbach's alpha, was excellent (α = 0.94) for this instrument. The SAS-SV showed one factor (unidimensional construct), and internal reliability was in the good range with an alpha coefficient of (α = 0.87). The prevalence of excessive users was 55.8 percent with highest symptom prevalence reported for tolerance and preoccupation. This study proved factor validity of the Arabic SAS and SAS-SV instruments and confirmed their internal reliability.

Mutation Analysis of Consanguineous Moroccan Patients with Parkinson's Disease Combining Microarray and Gene Panel.

During the last two decades, 15 different genes have been reported to be responsible for the monogenic form of Parkinson's disease (PD), representing a worldwide frequency of 5-10%. Among them, 10 genes have been associated with autosomal recessive PD, with PRKN and PINK1 being the most frequent. In a cohort of 145 unrelated Moroccan PD patients enrolled since 2013, 19 patients were born from a consanguineous marriage, of which 15 were isolated cases and 4 familial. One patient was homozygous for the common LRRK2 G2019S mutation and the 18 others who did not carry this mutation were screened for exon rearrangements in the PRKN gene using Affymetrix Cytoscan HD microarray. Two patients were determined homozygous for PRKN exon-deletions, while another patient presented with compound heterozygous inheritance (3/18, 17%). Two other patients showed a region of homozygosity covering the 1p36.12 locus and were sequenced for the candidate PINK1 gene, which revealed two homozygous point mutations: the known Q456X mutation in exon 7 and a novel L539F variation in exon 8. The 13 remaining patients were subjected to next-generation sequencing (NGS) that targeted a panel of 22 PD-causing genes and overlapping phenotypes. NGS data showed that two unrelated consanguineous patients with juvenile-onset PD (12 and 13 years) carried the same homozygous stop mutation W258X in the ATP13A2 gene, possibly resulting from a founder effect; and one patient with late onset (76 years) carried a novel heterozygous frameshift mutation in SYNJ1. Clinical analysis showed that patients with the ATP13A2 mutation developed juvenile-onset PD with a severe phenotype, whereas patients having either PRKN or PINK1 mutations displayed early-onset PD with a relatively mild phenotype. By identifying pathogenic mutations in 45% (8/18) of our consanguineous Moroccan PD series, we demonstrate that the combination of chromosomal microarray analysis and NGS is a powerful approach to pinpoint the genetic bases of autosomal recessive PD, particularly in countries with a high rate of consanguinity.

Focal drug-resistant epilepsy: Progress in care and barriers, a Morroccan perspective.

INTRODUCTION: The aim of this study is to determine the clinical, paraclinical, therapeutic and outcome aspects of drug resistant patients with epilepsy in our region and consequently to discuss methods that may improve the management of these patients. PATIENTS AND METHODS: This paper presents a retrospective study of 25 adult patients that were followed for focal drug resistant epilepsy in epileptology unit of the University Hospital of Fez, Morocco. RESULTS: This study recorded 25 patients including 48% of males and 52% of females. The mean age of patients was 24years-old. Hippocampal sclerosis was present in 28.5% of patients (7 cases); brain malformations were found in 19% of patients (5 cases); tumors were found in 24% of patients (6 cases); post-traumatic, post-surgical and anoxic-ischemic lesions were found in 28.5% of patients (7 cases). Resective epilepsy surgery was performed in 28,5% of patients (7 cases). Post surgical outcome was good for 5/7 patients (Engel I and II). CONCLUSION: The clinical characteristics, etiologies and clinical course of medically refractory focal epilepsy in our region are similar to that reported in the global literature. We also demonstrated a long delay between onset of seizures and surgery (15years range 8-34years) and barriers to epilepsy surgery.

Hibiscus sabdariffa increases hydroxocobalamin oral bioavailability and clinical efficacy in vitamin B12 deficiency with neurological symptoms.

The aim of the study was to evaluate the bioavailability and clinical benefits of oral new formulation (HB12 ) of hydroxocobalamin (Hdrx) with Hibiscus sabdariffa (HS). First, in an observational study, a cohort of 30 vitamin B12 -deficient patients (vit B12 < 200 pg/mL) with neurological symptoms received oral fixed dose of Hdrx containing 15 mg Hdrx daily for 10 days followed by 15 mg monthly. Clinical benefits were evaluated on haematological and biochemical parameters, and neurological improvement at days 10 and 90 compared to day 0. To understand the mechanism, intestinal mucosa from mice were mounted in vitro in Ussing chambers to measure Hdrx Fluxes. In the clinical study, serum vitamin B12 level increased from 55.1 ± 36.9 to 1330 ± 335.5 pg/mL at day 10 and 431.0 ± 24.27 pg/mL at day 90, without overt adverse effects. In mice ileum, (i) intestinal bioavailability of Hdrx increased in dose-dependent manner with HB12 . The apparent permeability of Hdrx was Papp = 34.9 ± 4.6 × 10-6 cm/s in the presence of 3 mg/mL (HB12 B) compared to the control Papp = 6.2 ± 0.7 × 10-6 cm/s. (ii) Total transepithelial electrical conductance (Gt ) increased in dose-dependent manner with HB12 , Gt = 161.5 ± 10.8 mS/cm² with HB12 B (Hdrx 1 mg + HS 3 mg) compared to the control Hdrx, Gt = 28.7 ± 4.0 mS/cm². In conclusion, the clinical study suggests that injections are not required when Hdrx is given orally. Intestinal bioavailability of Hdrx increased in vitro when it was used concomitantly with HS.

Cerebral venous thrombosis: a Moroccan retrospective study of 30 cases.

Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better than arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnosis. We studied 30 cases of CVT diagnosed in the department of neurology at the University Hospital of Fez (Morocco). Patients diagnosed with CVT signs between January 2003 and October 2007 were included in the study. Cerebral CT-scan was performed in 27 cases (90%) while the MRI examination was done in 18 patients (67%); and most patients (90%) received anticoagulant therapy. The mean age of our patients was of 29 years (age range between 18 days and 65 years). A female predominance was observed (70%). The clinical presentation of patients was dominated by: headache in 24 cases (80%), motor and sensory disability in 15 cases (50%), seizures in 10 cases (33%), consciousness disorder in 10 cases (33%). CVT was associated to post-partum in 10 cases (33%), infectious origin in 8 cases (26%), Behçet disease in 2 cases (7%), pulmonary carcinoma in 1 case, thrombocytemia in 1 case and idiopathic in 7 cases (23%). The evolution was good in 20 cases (67%), minor squelaes were observed in 6 patients (20%), while major squelaes were observed in 2 cases. Two cases of death were registered. The CVT is a pathology of good prognosis once the diagnosis is promptly established and early heparin treatment initiated.

Neural network underlying ictal pouting ("chapeau de gendarme") in frontal lobe epilepsy.

In order to determine the anatomical neural network underlying ictal pouting (IP), with the mouth turned down like a "chapeau de gendarme", in frontal lobe epilepsy (FLE), we reviewed the video-EEG recordings of 36 patients with FLE who became seizure-free after surgery. We selected the cases presenting IP, defined as a symmetrical and sustained (>5s) lowering of labial commissures with contraction of chin, mimicking an expression of fear, disgust, or menace. Ictal pouting was identified in 11 patients (8 males; 16-48 years old). We analyzed the clinical semiology, imaging, and electrophysiological data associated with IP, including FDG-PET in 10 and SEEG in 9 cases. In 37 analyzed seizures (2-7/patient), IP was an early symptom, occurring during the first 10s in 9 cases. The main associated features consisted of fear, anguish, vegetative disturbances, behavioral disorders (sudden agitation, insults, and fighting), tonic posturing, and complex motor activities. The epileptogenic zone assessed by SEEG involved the mesial frontal areas, especially the anterior cingulate cortex (ACC) in 8 patients, whereas lateral frontal onset with an early spread to the ACC was seen in the other patient. Ictal pouting associated with emotional changes and hypermotor behavior had high localizing value for rostroventral "affective" ACC, whereas less intense facial expressions were related to the dorsal "cognitive" ACC. Fluorodeoxyglucose positron emission tomography demonstrated the involvement of both the ACC and lateral cortex including the anterior insula in all cases. We propose that IP is sustained by reciprocal mesial and lateral frontal interactions involved in emotional and cognitive processes, in which the ACC plays a pivotal role.

Cerebellar ganglioglioma.

The cerebellar location of ganglioglioma (GG) is exceptional. We report one case of a 27-year-old man who underwent an intracranial hypertension syndrome and a static cerebellar syndrome. Brain magnetic resonance images revealed a cyst image in the vermis. Histological study after surgical removal, revealed a ganglioglioma tumor. Through this case and literature review, the authors discuss some epidemiological, histological, clinical, radiological and management features of this very rare tumor.

Infectious endocarditis complicated by an ischemic stroke and revealing Marfan syndrome.

Marfan syndrome is a systematic genetic disease of the connective tissue. The cardiac affection would predict the prognosis and ischemic stroke might complicate it. The purpose of this work is to discuss the mechanisms of the ischemic stroke in Marfan syndrome which have to be considered in all young patients of ischemic strokes. We report the case of a 17-year-old male patient who presented with right hemiparesis with brachio-facial dominance, hemihypoesthesia and Broca's aphasia; these symptoms were followed by partial right somato-motor epileptic seizure. The cerebral computed tomographic (CT) scan demonstrated early signs of ischemic stroke in the left Sylvian artery. Cardiovascular examination revealed a systolic murmur in the mitral site. Marfan syndrome with infectious endocarditis complicated by ischemic stroke was diagnosed. However, the family pathological history was negative. The Marfan syndrome diagnosis was approved considering the following criteria: Ligamentous hyperlaxity, crystalline ectopia and mitral valve prolapsus with mitral insufficiency. The patient benefited of antibiotherapy for 4 weeks. The patient underwent sessions of motor physical therapy and orthophonic rehabilitation. Then, cardiac surgery was carried out and valvuloplasty was performed. The surgical treatment confirmed the presence of mitral insufficiency and prolapsus of the big mitral valve and multiple friable anterior-posterior vegetations with broken cordage of the small mitral valve. Replacement of the mitral valve was achieved, and the post-surgery follow-ups were simple. The diagnosis of Marfan syndrome was based on well-defined criteria. The evolution of the patient was marked by a complete improvement of the cardiac and motor deficits, and disappearance of the Broca's aphasia. A fibroelastic disease such Marfan syndrome has to be considered in unexplained ischemic stroke in all young patients. Hence, the diagnosis of Marfan syndrome involves an anticipation of the neurovascular complications by early cardiovascular care.
