Outcomes of Acute Stroke Patients Requiring Mechanical Ventilation: Study Protocol for the SPICE Multicenter Prospective Observational Study.

BACKGROUND: Care pathways and long-term outcomes of acute stroke patients requiring mechanical ventilation have not been thoroughly studied. METHODS AND RESULTS: Stroke Prognosis in Intensive Care (SPICE) is a prospective multicenter cohort study which will be conducted in 34 intensive care units (ICUs) in the Paris, France area. Patients will be eligible if they meet all of the following inclusion criteria: (1) age of 18 years or older; (2) acute stroke (i.e., ischemic stroke, intracranial hemorrhage, or subarachnoid hemorrhage) diagnosed on neuroimaging; (3) ICU admission within 7 days before or after stroke onset; and (4) need for mechanical ventilation for a duration of at least 24 h. Patients will be excluded if they meet any of the following: (1) stroke of traumatic origin; (2) refusal to participate; and (3) privation of liberty by administrative or judicial decision. The primary endpoint is poor functional outcome at 1 year, defined by a score of 4 to 6 on the modified Rankin scale (mRS), indicating severe disability or death. Main secondary endpoints will include decisions to withhold or withdraw care, mRS scores at 3 and 6 months, and health-related quality of life at 1 year. CONCLUSIONS: The SPICE multicenter study will investigate 1-year outcomes, ethical issues, as well as care pathways of acute stroke patients requiring invasive ventilation in the ICU. Gathered data will delineate human resources and facilities needs for adequate management. The identification of prognostic factors at the acute phase will help to identify patients who may benefit from prolonged intensive care and rehabilitation. TRIAL REGISTRATION: NCT03335995.

Vascular cognitive impairment: Advances and trends.

The presence of vascular neurocognitive impairment (whatever the severity) is always associated with a functional impact and increased risk of dependency and institutionalization. However, vascular cognitive impairment remains underdiagnosed, and the mechanisms underlying post-stroke cognitive disorders are still poorly understood. However, the advent of new criteria and a standardized international neuropsychological battery is expected to lead to improved diagnosis and management, and the development of novel techniques (such as brain imaging and amyloid PET) should improve our understanding of the mechanisms underlying vascular cognitive impairment and help to identify potential targets for therapy.

Impact on obstetric outcome of third-trimester screening for small-for-gestational-age fetuses.

OBJECTIVES: To evaluate the performance of screening for small-for-gestational-age (SGA) fetuses by ultrasound biometry at 30-35 weeks' gestation, and to determine the impact of screening on obstetric and neonatal outcomes. METHODS: For this prospective cohort study, pregnant women were recruited from two French university maternity centers between 2003 and 2006. Performance measures of third-trimester biometry for the prediction of SGA, defined as estimated fetal weight < 10(th) centile, were analyzed. Obstetric outcomes and neonatal health status were compared, first, between SGA neonates diagnosed correctly at ultrasound examination (true positive (TP); n = 45) and SGA neonates that went undiagnosed (false negative (FN); n = 110) and, second, between non-SGA neonates identified as normal at ultrasound examination (true negative (TN); n = 1641) and non-SGA neonates diagnosed incorrectly as SGA (false positive (FP); n = 101). RESULTS: In the prediction of SGA, third-trimester ultrasound had a sensitivity of 29.0% (95% CI, 22.5-36.6%) and specificity of 94.2% (95% CI, 93.0-95.2%). Positive and negative predictive values were 30.8% (95% CI, 23.9-38.7%) and 93.7% (95% CI, 92.5-94.8%), respectively. One hundred and ten SGA neonates went undiagnosed at ultrasound. Compared to the TN neonates considered as of normal weight at ultrasound, planned preterm delivery (before 37 weeks) and elective Cesarean section for a fetal growth indication were 2.4 (P = 0.01) and 2.85 (P = 0.003) times more likely to occur, respectively, in the FP group of non-SGA neonates, diagnosed incorrectly as SGA during the antenatal period. There was no statistically significant difference in 5-min Apgar score < 7, cord blood pH at birth < 7.15 and need for neonatal resuscitation between the two subgroups (TN vs FP and TP vs FN). CONCLUSIONS: The performance of third-trimester ultrasound screening for SGA seems poor, as it misses the diagnosis of a large number of SGA neonates. The consequences of routine screening for SGA in a low-risk population may lead to unnecessary planned preterm deliveries and elective Cesarean sections in FP pregnancies, without improved neonatal outcome in the FN pregnancies.

A weighted and directed interareal connectivity matrix for macaque cerebral cortex.

Retrograde tracer injections in 29 of the 91 areas of the macaque cerebral cortex revealed 1,615 interareal pathways, a third of which have not previously been reported. A weight index (extrinsic fraction of labeled neurons [FLNe]) was determined for each area-to-area pathway. Newly found projections were weaker on average compared with the known projections; nevertheless, the 2 sets of pathways had extensively overlapping weight distributions. Repeat injections across individuals revealed modest FLNe variability given the range of FLNe values (standard deviation <1 log unit, range 5 log units). The connectivity profile for each area conformed to a lognormal distribution, where a majority of projections are moderate or weak in strength. In the G29 × 29 interareal subgraph, two-thirds of the connections that can exist do exist. Analysis of the smallest set of areas that collects links from all 91 nodes of the G29 × 91 subgraph (dominating set analysis) confirms the dense (66%) structure of the cortical matrix. The G29 × 29 subgraph suggests an unexpectedly high incidence of unidirectional links. The directed and weighted G29 × 91 connectivity matrix for the macaque will be valuable for comparison with connectivity analyses in other species, including humans. It will also inform future modeling studies that explore the regularities of cortical networks.

Rhabdomyolysis with Acute Renal Failure and Deep Vein Thrombosis Induced by Antipsychotic Drugs: A Case Report.

Atypical antipsychotics, the first line therapy for schizophrenia, have already been reported as causing rhabdomyolysis or isolated elevation in serum creatine kinase (SCK). This case report dealing with rhabdomyolysis in a 25-year-old man treated with antipsychotics is particularly unusual, due to the extremely high elevation in SCK and the ensuing acute renal failure. He was treated with loxapine 400 mg/day and risperidone 4 mg/day for 4 days and then loxapine was replaced by levomepromazine 300 mg/day. A series of laboratory examinations showed: SCK 43 650 UI/L, creatinine 392 µmol/L. An acute renal failure (acute tubular necrosis) after iatrogenic rhabdomyolysis was diagnosed, requiring hemodialysis. Furthermore, the patient also developed a deep vein thrombosis (DVT) attributed to his antipsychotic treatment. This case underlines the importance of taking rhabdomyolysis and DVT risk factors into account in patients treated with antipsychotics. Indeed, in this case we note that rhabdomyolysis was probably promoted by the interruption and the reintroduction of the treatment more than by possible dehydration, because no other risk factor could be identified.

[Withdrawal of artificial nutrition and hydration in severe stroke: medical, legal and ethical considerations]. / Aspects médicaux, législatifs et éthiques de l'arrêt de la nutrition et de l'hydratation artificielles dans l'accident vasculaire cérébral grave.

In the majority of cases, severe stroke is accompanied by difficulty in swallowing and an altered state of consciousness requiring artificial nutrition and hydration. Because of their artificial nature, nutrition and hydration are considered by law as treatment rather basic care. Withdrawal of these treatments is dictated by the refusal of unreasonable obstinacy enshrined in law and is justified by the risk of severe disability and very poor quality of life. It is usually the last among other withholding and withdrawal decisions which have already been made during the long course of the disease. Reaching a collegial consensus on a controversial decision such as artificial nutrition and hydration withdrawal is a difficult and complex process. The reluctance for such decisions is mainly due to the symbolic value of food and hydration, to the fear of "dying badly" while suffering from hunger and thirst, and to the difficult distinction between this medical act and euthanasia. The only way to overcome such reluctance is to ensure flawless accompaniment, associating sedation and appropriate comfort care with a clear explanation (with relatives but also caregivers) of the rationale and implications of this type of decision. All teams dealing with this type of situation must have thoroughly thought through the medical, legal and ethical considerations involved in making this difficult decision.

An update on brain imaging in transient ischemic attack.

Neuroimaging is critical in the evaluation of patients with transient ischemic attack (TIA) and MRI is the recommended modality to image an ischemic lesion. The presence of a diffusion (DWI) lesion in a patient with transient neurological symptoms confirms the vascular origin of the deficit and is predictive of a high risk of stroke. Refinement of MR studies including high resolution DWI and perfusion imaging using either MRI or CT further improve the detection of ischemic lesions. Rapid etiological work-up includes non-invasive imaging of cervical and intracranial arteries to search for symptomatic stenosis/occlusion associated with an increased risk of stroke.

Impaired sexual activity in young ischaemic stroke patients: an observational study.

BACKGROUND AND PURPOSE: The present study sought to determine the impact of stroke on sexual function and well-being in a cohort of young ischaemic stroke patients and identify factors associated with impairment. METHODS: Over a 2-year period, all patients aged 60 or under with ischaemic stroke or transient ischaemic attack (n = 156) were included. Information on sexual function and well-being was obtained by means of a paper questionnaire mailed to participants 1 year after their stroke. Impaired sexual activity (ISA) was defined as a decline in sexual function and/or satisfaction. Psychological well-being was evaluated on the Hospital Anxiety and Depression Scale (HADS). RESULTS: The response rate was 67% (n = 104). Thirty of these responders (29%) reported ISA. Patients with ISA had a higher HADS score (19.7 vs. 11.2 in patients with no impairment; P < 0.001), anxiety score (10.0 vs. 6.3; P < 0.001) and depression score (8.7 vs. 4.8; P < 0.001) and were more likely to have left brain lesions (70% vs. 30%; P < 0.001) and use angiotensin-converting enzyme (ACE) inhibitors (73% vs. 31%; P < 0.001) and diuretics (50% vs. 19%; P = 0.003). In a stepwise logistic regression, depression (odds ratio 9.1, 95% confidence interval 2.45-33.46; P = 0.001) and ACE inhibitor use (odds ratio 6.0, 95% confidence interval 2.11-17.28; P = 0.001) were associated with ISA. CONCLUSIONS: Impaired sexual activity was reported by almost one-third of younger patients 1 year after ischaemic stroke. Factors associated with post-stroke ISA may include specific medications and depression rather than the characteristics of the stroke per se.

MR screening of candidates for thrombolysis: How to identify stroke mimics?

Stroke mimics account for up to a third of suspected strokes. The main causes are epileptic deficit, migraine aura, hypoglycemia, and functional disorders. Accurate recognition of stroke mimics is important for adequate identification of candidates for thrombolysis. This decreases the number of unnecessary treatments and invasive vascular investigations. Correctly identifying the cause of symptoms also avoids delaying proper care. Therefore, this pictorial review focuses on what the radiologist should know about the most common MRI patterns of stroke mimics in the first hours after onset of symptoms. The issues linked to the accurate diagnosis of stroke mimics in the management of candidates for thrombolysis will be discussed.

Treatment of acute decompensation of maple syrup urine disease in adult patients with a new parenteral amino-acid mixture.

BACKGROUND: Acute decompensation of maple syrup urine disease (MSUD) is usually treated by enteral feeding with an amino-acid mixture without leucine (Leu), valine or isoleucine. However, its administration is ineffective in cases of gastric intolerance and some adult patients refuse enteral feeding via a nasogastric tube. We developed a new parenteral amino-acid mixture for patients with MSUD. METHODS: Seventeen decompensation episodes in four adult patients with MSUD treated with a parenteral amino-acid mixture (group P) were compared to 18 previous episodes in the same patients treated by enteral feeding (group E). RESULTS: The mean Leu concentration at presentation was similar in the groups P and E (1196.9 µmol/L and 1212.2 µmol/L, respectively). The mean decrease in the Leu concentration during the first 3 days of hospitalisation was significantly higher in group P than group E (p = 0.0026); there were no side effects. The mean duration of hospitalisation was similar (4 vs. 4.5 days, p = NS). No patient in group P deteriorated whereas one patient in group E required dialysis. CONCLUSION: This new parenteral amino-acid mixture is safe and allows efficient Leu concentration decrease during acute MSUD decompensation episodes in adults. Its use avoids the need for nasogastric tube insertion.

Predictors of newly diagnosed atrial fibrillation in cryptogenic stroke: a cohort study.

BACKGROUND AND PURPOSE: A significant proportion of cryptogenic ischaemic strokes are due to paroxysmal atrial fibrillation (AF). As paroxysmal AF appears to inexorably progress to persistent or permanent AF, this study with long-term follow-up was designed to establish the profile of patients who developed AF after hospital discharge. METHODS: All patients with cryptogenic ischaemic stroke over a 1-year period were included (n = 164). Patients were prospectively followed up at the outpatient clinic. Information on long-term outcome included the presence of newly diagnosed AF (NDAF). A specific NDAF assessment was performed at least 2 years after the index stroke using a structured telephone interview. Baseline clinical, laboratory, and echocardiographic data of these patients were retrospectively recorded. Independent predictive factors were then used to produce a predictive grading score for NDAF, derived by logistic regression analysis. RESULTS: With a median follow-up of 854 days, 22 cases of NDAF (13%) were observed. On multivariate analysis, factors associated with NDAF were age ≥72 years (two points), history of coronary artery disease (one point) or stroke (one point), and left atrial area ≥16 cm(2) (two points) (total score ranging from 0 to 6). Patients with a score ≤1 point did not have NDAF during follow-up. CONCLUSIONS: In cryptogenic ischaemic stroke, the NDAF score can be used to target patients at high risk of developing AF after hospital discharge, as a score of 0-1 was highly predictive of the absence of NDAF during follow-up. These results need to be confirmed in prospective studies.

Autosomal dominant familial spastic paraplegia is genetically heterogeneous and one locus maps to chromosome 14q.

Autosomal dominant familial spastic paraplegia (FSP) is a degenerative disorder of unknown aetiology characterized by a progressive spasticity of the legs. Three families with autosomal dominant FSP of early onset were analysed in linkage studies using highly polymorphic microsatellite markers. Close linkage to a group of markers on chromosome 14q (maximum multipoint lodscore z = 10) was observed in one family. This chromosome 14q candidate region was entirely excluded in the two other families, providing evidence of genetic heterogeneity within a homogeneous clinical form of FSP.

[Symptomatic giant Virchow-Robin spaces]. / Dilatations géantes des espaces de Virchow-Robin symptomatiques.

INTRODUCTION: Perivascular spaces, known as Virchow-Robin spaces (VRS), may become massively enlarged but are usually an incidental finding. However, a few reports on patients with unusually large VRS have mentioned association with neurological symptoms. We report a series of three symptomatic patients with extremely wide Virchow-Robin spaces documented on brain magnetic resonance imaging (MRI). METHODS: We retrospectively analyzed the medical records and brain MRI of three symptomatic patients, who had been diagnosed with VRS widening. CASE REPORTS: In all three patients, the unusual widening of the VRS was located within the subcortical white matter with asymmetric distribution. Their neurological symptoms were epilepsy and neurological deficits which correlated well with the lesions seen on the MRI. Two patients had associated white matter hyperintensities: in the first case associated gliosis and in the second case, with vascular leukoencephalopathy. CONCLUSIONS: Enlarged symptomatic VRS are rare. The underlying pathophysiological mechanisms remain uncertain. We report three cases with symptomatic giant dilatation of the Virchow-Robin spaces.

Thrombolysis in cervical artery dissection--data from the Cervical Artery Dissection and Ischaemic Stroke Patients (CADISP) database.

OBJECTIVE: To examine whether thrombolysis for stroke attributable to cervical artery dissection (CeAD(Stroke) ) affects outcome and major haemorrhage rates. METHODS: We used a multicentre CeAD(Stroke) database to compare CeAD(Stroke) patients treated with and without thrombolysis. Main outcome measures were favourable 3-month outcome (modified Rankin Scale 0-2) and 'major haemorrhage' [any intracranial haemorrhage (ICH) and major extracranial haemorrhage]. Adjusted odds ratios [OR (95% confidence intervals)] were calculated on the whole database and on propensity-matched groups. RESULTS: Among 616 CeAD(Stroke) patients, 68 (11.0%) received thrombolysis; which was used in 55 (81%) intravenously. Thrombolyzed patients had more severe strokes (median NIHSS score 16 vs. 3; P < 0.001) and more often occlusion of the dissected artery (66.2% vs. 39.4%; P < 0.001). After adjustment for stroke severity and vessel occlusion, the likelihood for favourable outcome did not differ between the treatment groups [OR(adjusted) 0.95 (95% CI 0.45-2.00)]. The propensity matching score model showed that the odds to recover favourably were virtually identical for 64 thrombolyzed and 64 non-thrombolyzed-matched CeAD(Stroke) patients [OR 1.00 (0.49-2.00)]. Haemorrhages occurred in 4 (5.9%) thrombolyzed patients, all being asymptomatic ICHs. In the non-thrombolysis group, 3 (0.6%) patients had major haemorrhages [asymptomatic ICH (n = 2) and major extracranial haemorrhage (n = 1)]. CONCLUSION: As thrombolysis was neither independently associated with unfavourable outcome nor with an excess of symptomatic bleedings, our findings suggest thrombolysis should not be withheld in CeAD(Stroke) patients. However, the lack of any trend towards a benefit of thrombolysis may indicate the legitimacy to search for more efficient treatment options including mechanical revascularization strategies.

Weight consistency specifies regularities of macaque cortical networks.

To what extent cortical pathways show significant weight differences and whether these differences are consistent across animals (thereby comprising robust connectivity profiles) is an important and unresolved neuroanatomical issue. Here we report a quantitative retrograde tracer analysis in the cynomolgus macaque monkey of the weight consistency of the afferents of cortical areas across brains via calculation of a weight index (fraction of labeled neurons, FLN). Injection in 8 cortical areas (3 occipital plus 5 in the other lobes) revealed a consistent pattern: small subcortical input (1.3% cumulative FLN), high local intrinsic connectivity (80% FLN), high-input form neighboring areas (15% cumulative FLN), and weak long-range corticocortical connectivity (3% cumulative FLN). Corticocortical FLN values of projections to areas V1, V2, and V4 showed heavy-tailed, lognormal distributions spanning 5 orders of magnitude that were consistent, demonstrating significant connectivity profiles. These results indicate that 1) connection weight heterogeneity plays an important role in determining cortical network specificity, 2) high investment in local projections highlights the importance of local processing, and 3) transmission of information across multiple hierarchy levels mainly involves pathways having low FLN values.

Anatomical and radiological description of ligament insertions on the radial aspect of the scaphoid bone.

Anatomical studies on the radial side of the scaphoid mention inter-ligamentous connections, but without detailed description of their relations to one another. The purpose of this study was to provide an anatomical and radiological description of the ligamentous structure on the radial side of the scaphoid. High-field 3-Tesla 3D MRI scans of 7 cadaveric formaldehyde-fixed wrists were performed to assess the presence and location of each ligament. Dissection was performed in 10 wrists under microscopy on the radial side to assess the dimensions, anatomical variations and angles between ligaments in various wrist positions during in intracarpal pronation/supination, flexion/extension and ulnar/radial deviation. This study confirmed that the same ligament configuration was found on MRI and on dissection. The scaphotrapezial ligament, dorsal intercarpal ligament and radial collateral ligament fibers merge along the dorsal ridge of the scaphoid. The fibers of the radial collateral and radioscaphocapitate ligaments could be distinguished in only 4/10 specimens. Wrist position changes from intracarpal pronation to supination produced major changes in angle between the scaphotrapezial and dorsal intercarpal ligaments, while other position changes affected this angle only slightly. 3D MRI sequences allow these structures to be systematically analyzed in case of scapholunate instability. Further studies should be conducted to assess the biomechanical properties of these ligaments and the clinical consequences of isolated injury in this region.

[Postnatal outcome from polyhydramnios without sonographic abnormalities]. / Issue postnatale en cas d'hydramnios sans anomalies morphologiques à l'échographie anténatale.

OBJECTIVES: To assess adverse outcome of polyhydramnios without morphological abnormalities and to determine the factors associated with an adverse outcome. METHODS: This is a retrospective observational cohort study conducted in a French tertiary care unit between 2008 and 2018 including all women with singleton pregnancy complicated by polyhydramnios. Presence of morphological abnormality was an exclusion criteria. The primary outcome was the rate of adverse outcome, defined by a composite criterion including death or postnatal discovery of malformation or chronic pathology. Maternal, obstetrical, paediatric and polyhydramnios characteristics were collected. RESULTS: Ninety-one women with polyhydramnios were included. The rate of adverse outcome was 24.2% (22/91). This rate was 20,3% in case of idiopathic polyhydramnios and 33,3% in case of maternal diabetes associated. The postnatal mortality rate was 5.5%. The rate of malformations not diagnosed in antenatal was 11%. Obesity (50% vs. 18,8%; P=0,004), early diagnosis (72,7% before 32 WG vs. 44,9%; P=0,02), and severity of polyhydramnios (22,7% vs. 4,3% in severe polyhydramnios; P=0,01) were associated significantly with an adverse outcome. In these cases, the incidence of preterm delivery was higher. CONCLUSION: Polyhydramnios must have second-line ultrasound, including isolated maternal diabetes. A systematic genetic assessment can be discussed.

Analysis of pentacyclic triterpenes by LC-MS. A comparative study between APCI and APPI.

The analytical performances of three atmospheric-pressure sources, electrospray (ESI), atmospheric-pressure chemical ionization (APCI), and atmospheric-pressure photoionization (APPI), were evaluated for the analysis of pentacyclic triterpenes in liquid chromatography-mass spectrometry (LC-MS). Among these sources, APPI and APCI are particularly well adapted to sensitive analyses of pentacyclic triterpenes by LC-MS. Detection parameters were optimized for both the sources, and the effects of three dopants (toluene, acetone and anisole) on the detection (sensitivity and ion fingerprints in MS spectra) were studied in detail for APPI-MS.The limits of quantification were measured under selected ion monitoring conditions, in the range of 0.005-0.015 mg l(-1) and 0.002-0.84 mg l(-1) in APPI and APCI, respectively, depending on the studied pentacyclic triterpene. Overall, APPI was found more sensitive than APCI in positive ion mode, whereas APCI shows the greatest sensitivity for acidic triterpenes in negative ion mode.Following this study, the developed LC-MS method was used for the characterization of pentacyclic triterpenes in three plant extracts. High amounts of betulinic acid, betulinic aldehyde and betulinic aldehyde acetate were observed in plane bark. The main component of birch bark is betulin and extracts of okoume resin exhibit high amounts of alpha- and beta-amyrin.

[Clinical and psychopathological profile of women victims of psychological partner violence]. / Profil clinique et psychopathologique des femmes victimes de violences conjugales psychologiques.

BACKGROUND: Partner violence is a serious public health problem, due to their potential short-, medium- or long-term physical and psychological consequences. Violence is unbearable when it occurs between family members, and often remains unrevealed, invisible, hidden and repeated. The woman possibly feels trapped in a relationship of imprisonment. International studies have well-explored the psychopathological aspects of physical and sexual abuse within couples, but few explored the clinical profile of women victims of psychological violence or moral harassment. This study aims to define the clinical and psychopathological profile of women who are victims of psychological intimate partner violence. METHODS: We contacted 628 women who consulted consecutively at the emergency ward of a university hospital covering a 300,000 catchment area. The telephone screening of psychological violence was therefore carried out using the Women's Experience with Battering (WEB) questionnaire (N=226). An optional clinical interview was given to the women declaring themselves as victims of psychological intimate partner violence (N=56) to evaluate the life events and the psychiatric disorders according to the DSM-IV. Finally, 43 participants (77%) gave their opinion on the qualitative aspects of the WEB questionnaire and their level of ease with this report. RESULTS: In 63% (N=35) of the cases, the victims and their partners had a rather high socioprofessional level. Women refer to emergency ward mostly for complaint of vague idiopathic pain (49%) or for psychiatric disorders (52%) with predominance of anxiety (28%) or addictive disorders (19%). The prevalence of potentially traumatic life events was found to be high in this group (83%). The traumatic psychological intimate partner violence was associated with a heightened prevalence of psychiatric comorbidities, like anxiety (72%), depression (100%), posttraumatic stress disorder (100%), and addiction to alcohol (100%) or another psychoactive substance (50%). Finally, 44% of the women linked their gynecoobstetrical history to their psychological state of the relationship. CONCLUSION: Even if the psychopathological profile is relatively close, the sociodemographic profile of victims of psychological intimate partner violence is singularly different than that of the victims of physical or sexual abuse. This work underlines the necessity of a systematic screening of these aspects of violence in emergency medical services.

[Epilepsy and stroke]. / Epilepsie et accident vasculaire cérébral.

Stroke is associated with an increased risk of subsequent seizures and epilepsy. Cerebrovascular lesions are the leading cause of epilepsy in the elderly, ahead of degenerative disorders, brain tumors and head trauma, accounting for up to one-third of newly diagnosed seizures in this population. The frequency of seizures in stroke victims varies from 5 to 20%, but only a minority will develop epilepsy. Based on differences in their presumed pathophysiology, seizures after stroke are usually divided into early and late seizures, according to various definitions. Early seizures are usually defined as those occurring within one or two weeks after stroke; late seizures usually occur within the first year after stroke. Several risk factors of seizures have been identified; stroke subtype and cortical location being the best-characterized predictors of seizure development. The optimal timing and type of anti-epileptic treatment remain debated. Several findings suggest that the majority of first generation anti-epileptic drugs are not the best choice in stroke patients.
