RESUMO
OBJECTIVES: We assessed the quality of life, sleep, depression, anxiety, and stress in people with pharmacoresistant epilepsy (PRE) and newly diagnosed epilepsy (NDE). We also assessed the influence of sleep, depression, anxiety, and stress on the quality of life (QOL) and the complex association between these factors. METHODS: We recruited 80 PRE and 70 NDE people attending the epilepsy clinic. We assessed QOL, sleep quality, daytime sleepiness, and mood using the quality of life in epilepsy-31 inventory (QOLIE-31), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), and depression anxiety stress scale (DASS-21). We compared the results between the two groups of epilepsy populations. We performed univariate and multivariate linear regression to determine the factors affecting the QOLIE-31 total score. We applied Spearman's rank correlation to find the interrelationship between variables influencing QOL. RESULTS: We found significantly lower QOLIE-31 total scores (p = .001) in PRE compared to NDE. The PSQI and ESS did not differ significantly between the PRE and NDE groups. Anxiety (p = .002) and stress (p = .003) scores were significantly higher in PRE than in NDE. QOLIE-31 total scores showed a negative correlation with PSQI as well as symptoms of depression, anxiety, and stress scores in both groups. Multiple linear regression analysis revealed depression as a major factor influencing the QOLIE-31 total score in PRE (p = .001) and NDE (p = .003). We found significant complex associations between PSQI, depression, anxiety, stress, and QOLIE total scores in both groups. SIGNIFICANCE: The QOL is poorer for people with PRE than for those with NDE. Depression is a major determinant of QOL in PWE. These factors need to be considered to improve the QOL in epilepsy.

OBJECTIVE: Comparison of cardiovascular risk factors, atherosclerosis, and psychological distress among adults with refractory versus well-controlled epilepsy. METHODS: The cross-sectional study consisted of two groups of 40 people each: Group I - People with well-controlled epilepsy, Group II - People with refractory epilepsy. Age- and gender-matched people of 20-50 years were recruited. People who were diabetic, smokers, hypertensive, alcoholic, pregnant, with infections, and lactating women were excluded from the study. Biochemical parameters, fasting glucose, lipid profile, fasting insulin, leptin, adiponectin, Lp[a], hsCRP, TyG INDEX, HOMA1-%S, HOMA1-IR, HOMA1-%B, QUICKI, FIRI, AIP, AC, CLTI, MLTI, CRI-I, CRI-II, and CIMT were estimated. Stress levels [PSS-10, GAD-7 & PHQ-9] were assessed based on the scoring system from the questionnaires. RESULTS: The existence of metabolic syndrome, levels of triglycerides, TyG index, MDA, OSI, CIMT, AIP, and stress scores [PSS-10, GAD-7 & PHQ-9] were significantly higher in the refractory-epilepsy group in comparison to the well-controlled group. There were associations between LDL -C and CIMT as well as between GAD-7 and CIMT among all the study subjects. There were no significant differences in the levels of glucose homeostasis parameters, hsCRP, leptin, adiponectin, and Lp[a] between the two groups. Based on the ROC analysis, MDA [AUC = 0.853] and GAD-7 [AUC = 0.900] are useful in the differential diagnosis of the study groups. CONCLUSION: People with refractory epilepsy had increased levels of vascular risk factors, atherosclerosis, and stress levels compared to people with well-controlled epilepsy. Suitable disease management and therapeutic approaches to address cardiovascular and psychological distress could be planned out among people with refractory epilepsy to improve their quality of life.

OBJECTIVES: Carbamazepine (CBZ) is a first-line antiseizure drug used for focal onset seizures. It exhibits inter-individual variability in plasma carbamazepine levels and there are both genetic and non-genetic factors having a role in the requirement of CBZ maintenance dose. The aim was to study the influence of EPHX1 c.337 T>C and UGT2B7*2 genetic polymorphisms on CBZ maintenance dose requirement in persons with epilepsy. METHODS: Persons with epilepsy (PWE) of both gender of age 15-65 years on carbamazepine monotherapy who had been taking same maintenance dose for one year were eligible. Five milliliter of venous blood was collected in 10% EDTA under aseptic precautions. After centrifugation, the cellular component was used for DNA extraction and genotyping. For three genotypes of EPHX1 c.337 T>C and UGT2B7*2, the differences in mean carbamazepine dose were analyzed using Analysis of Variance (ANOVA). An unpaired t-test was used to draw a comparison between the genotypes and CBZ maintenance dose requirement for dominant and recessive models of EPHX1 c.337 T>C and UGT2B7*2. A value of p<0.05 was considered to be statistically significant. RESULTS: For UGT2B7*2 (rs 7439366), CT required a higher dose (CT 626 mg/day and TT 523 mg/day) but not found to be significant (p-value 0.167). PWE carrying CT genotype of EPHX1 c.337 T>C had 62 mg higher dose when compared to homozygous mutant CC (590 mg/day for CT and 528 mg/day for CC) but p-value was not found to be significant (p-value 0.835). CONCLUSIONS: The results of our study done in 115 PWE showed there was a lack of association between SNPs of EPHX1 c.337 T>C, UGT2B7*2 and CBZ maintenance dose requirement in Southern part of India and this finding has to be confirmed in a larger sample size.

OBJECTIVE: Temporal lobe epilepsy (TLE) is often associated with autonomic manifestations. Sudden unexpected death in epilepsy (SUDEP) is a leading cause of mortality in epilepsy. Cardiac disturbances and autonomic dysfunction are the potential mechanisms behind SUDEP. Though heart rate variability (HRV) and autonomic function tests are well studied in drug-resistant temporal lobe epilepsy, there is a paucity of data on baroreflex sensitivity (BRS), a better marker of cardiac mortality in this population. We aimed to study the interictal cardiac autonomic function and BRS in people living with drug-resistant temporal lobe epilepsy compared to healthy controls. MATERIALS AND METHODS: Thirty drug-resistant temporal lobe epilepsy (TLE) individuals and thirty healthy volunteers were recruited. Heart rate variability at rest, heart rate and blood pressure (BP) at rest, during deep breathing, postural change, BP response to isometric handgrip exercise, and baroreflex sensitivity were recorded in all study participants. The results were analyzed and compared between the two groups. RESULTS: Compared to controls, the resting heart rate, HRV, parasympathetic reactivity test, and BRS significantly differed in people living with drug-resistant TLE. Time-domain indices including SDNN (p < 0.001), RMSSD (p < 0.001), NN50 (p < 0.001), and pNN50 (p < 0.001) were significantly reduced in the patients compared to controls. In frequency-domain indices, the total power was reduced (p < 0.001) in drug-resistant TLE. The parasympathetic reactivity such as changes in heart rate during deep breathing (E: I) (p < 0.02) and postural change (30:15) (p < 0.005) were significantly reduced in the patients. Baroreflex sensitivity was also significantly reduced in the drug-resistant TLE group (p < 0.001). CONCLUSION: The present study findings are suggestive of parasympathetic dysfunction in drug-resistant TLE. Reduced HRV and BRS may increase the risk of SUDEP in people living with epilepsy.

BACKGROUND AND AIMS: Drug-resistant epilepsy (DRE) is a common and important neurological problem to identify with scope for curative surgical treatment if underlying cause is delineated. There are very few prospective structured studies in our population. This study aimed to look at the neuroimaging profile of DRE presenting in a tertiary care center in South India. MATERIALS AND METHODS: All patients diagnosed clinically as DRE as per International League Against Epilepsy (ILAE) criteria and who underwent magnetic resonance imaging (MRI) over a period of 24 months were included in the study. Their clinical and MRI features were documented and analyzed. RESULTS: A total of 150 patients diagnosed with DRE were included in the study. Clinically, 96 of them presented with generalized tonic-clonic seizures (GTCS), 36 with complex partial seizures (CPS), 14 with simple focal seizures, and two each with atonic seizures and focal seizures with secondary generalization. Magnetic resonance imaging (done in 1.5 T) was normal in 32%. In those with abnormal MRI, mesial temporal sclerosis (MTS) was the commonest pathology seen in 41.3%, followed by cortical malformations (6.7%), tumors (2.6%), vascular malformations (2.7%), and other nonspecific lesions (12%). CONCLUSION: The clinical and neuroimaging profile of DRE showed that DRE is more common in younger age (of less than 30 years); presents mainly with GTCS or CPS; mesial temporal sclerosis is the commonest underlying pathology which was bilateral in 8.6%; temporal lobe lesions predominate (49.3% of all DRE); and cortical malformation, low-grade tumors, and vascular lesions are other important causes.

Sturge-Weber syndrome (SWS) is a sporadic congenital neuro-cutaneous anomaly with capillary-venous malformation involving the brain, eye, and the ophthalmic division of the trigeminal nerve. In these cases, physiological changes in pregnancy, including hormonal and hemodynamic changes, may predispose to increased seizure frequency and even a life-threatening intracranial haemorrhage. There are only few case reports available about the management of women with pregnancy and SWS. We report two patients with SWS diagnosed in childhood and managed during pregnancy and reviewed the outcomes and complications during pregnancy in women with this disorder.

OBJECTIVE: Epilepsy is one of the most prevalent neurological conditions and carbamazepine is a commonly used anti-seizure drug (ASD), especially in developing nations. There are reports of carbamazepine causing atrioventricular conduction defects and autonomic dysfunctions and its implication in Sudden Unexpected Death in Epilepsy (SUDEP) is controversial. We planned this study to assess the effect of carbamazepine (CBZ) on autonomic function compared to other ASDs in persons with epilepsy. METHODS: In this cross-sectional study, we assessed the sympathetic and parasympathetic autonomic functions in persons with epilepsy (PWE) on CBZ versus other anti-seizure monotherapy using tests of heart rate variability including its time-, frequency- and non-linear domains, heart rate response to deep breathing, valsalva maneuver, and blood pressure response to isometric handgrip. RESULTS: Persons with epilepsy on CBZ monotherapy did not show a significant reduction in the time domain parameter SDRR compared to other ASDs used as monotherapy (mean⯱â¯SD, 38.04⯱â¯18.75â¯ms vs 44.37⯱â¯20.35â¯ms; pâ¯=â¯0.125). However, PWE on CBZ had significantly lower time-domain measurements including RMSSD (mean⯱â¯SD 31.95⯱â¯17.29â¯ms vs 42.02⯱â¯22.29â¯ms; pâ¯=â¯0.018), SDSD (mean⯱â¯SD 31.91⯱â¯17.26â¯ms vs 41.96⯱â¯22.27â¯ms; p 0.018), and pNN50 [median (IQR) 05.45(0.69-25.37) vs 16.38(2.32-36.83); pâ¯=â¯0.030]. Frequency domain measures of HRV, heart rate responses to deep breathing, valsalva maneuver and tilt-testing and BP responses to valsalva and tilt-testing were not significantly different between the groups. CONCLUSION: The findings of our study indicate reduced parasympathetic activity in persons on CBZ monotherapy compared to other ASDs, which may pose risk of SUDEP. Carbamazepine may thus be avoided in those at risk of autonomic dysfunction and SUDEP.

The diagnosis of neurocysticercosis in pregnancy is challenging, even in endemic areas, as other neurological conditions with similar manifestations are common. Obstetricians and physicians may be reluctant to do neuroimaging in pregnancy and often the availability is limited in endemic areas. Management of neurocysticercosis depends on the symptomatology. In those presenting with features of increased intracranial pressure early treatment is necessary, taking into consideration the gestational age and the maternal condition at presentation. Presence of intraventricular cysts causing obstructive hydrocephalus necessitates their removal due to the risk of intracranial hypertension which could be life-threatening, particularly peripartum. We report a case of a woman with intraventricular neurocysticercosis, who presented in the third trimester, and described the management dilemmas that were encountered. The differential diagnoses and other aspects of the medical and surgical management of neurocysticercosis in pregnancy are also discussed.
RESUMO
Purpose: Drawing differential diagnoses to a Neuro-ophthalmology clinical scenario is a difficult task for a neurology trainee. The authors conducted a study to determine if a mobile application specialized in suggesting differential diagnoses from clinical scenarios can complement clinical reasoning of a neurologist in training. Methods: A cross-sectional multicenter study was conducted to compare the accuracy of neurology residents versus a mobile medical app (Neurology Dx) in drawing a comprehensive list of differential diagnoses from Neuro-ophthalmology clinical vignettes. The differentials generated by residents and the App were compared with the Gold standard differential diagnoses adjudicated by experts. The prespecified primary outcome was the proportion of correctly identified high likely gold standard differential diagnosis by residents and App. Results: Neurology residents (n = 100) attempted 1500 Neuro-ophthalmology clinical vignettes. Frequency of correctly identified high likely differential diagnosis by residents was 19.42% versus 53.71% by the App (P < 0.0001). The first listed differential diagnosis by the residents matched with that of the first differential diagnosis adjudicated by experts (gold standard differential diagnosis) with a frequency of 26.5% versus 28.3% by the App, whereas the combined output of residents and App scored a frequency of 41.2% in identifying the first gold standard differential correctly. The residents correctly identified the first three and first five gold standard differential diagnosis with a frequency of 17.83% and 19.2%, respectively, as against 22.26% and 30.39% (P < 0.0001) by the App. Conclusion: A ruled based app in Neuro-ophthalmology has the potential to complement a neurology resident in drawing a comprehensive list of differential diagnoses.

OBJECTIVES: Epilepsy is a common neurological ailment contributing to significant disability. About one-third of all epilepsy patients would be refractory to two or more medications. Brivaracetam (BRV) is one of the newer anti-seizure medications on which extensive data is available, but its efficacy as an early add-on agent (first/second adjuvant) is unclear. The principal objective of this review is to assess the efficacy of BRV as an early add-on agent in refractory Focal Onset Seizures (FOS) and its pharmacology and usage in various clinical situations associated with seizures. METHODS: We searched two databases, Medline and Cochrane Central, for papers on BRV and FOS, and selected six studies with randomized parallel control design to extract the data for a meta-analysis. We also did a comprehensive review of the available literature on its pharmacology and usage in various clinical scenarios associated with seizures. RESULTS: For the meta-analysis, we extracted 145 articles; six studies fulfilled the selection criteria that gave us data on 1938 patients who received Brivaracetam as an early add-on agent in FOS. The Risk Ratio (RR) (95% CI) for 50% responders across the trials was 1.88 (1.55-2.29). Similarly, the overall RR (95% CI) was 5.82 (2.15-15.70) for seizure freedom. CONCLUSION: Our analysis provides moderate evidence for Brivaracetam as an effective agent as an early adjuvant in FOS. Its efficacy for several other indications needs further clinical trials and evaluation.

Pregnant women presenting with isolated cranial palsies are uncommon. Isolated sixth nerve (abducens nerve) palsy can occur for a variety of reasons and neuroimaging is often performed to identify an underlying cause. We report a case of a woman in her third pregnancy with preeclampsia who presented with an isolated sixth nerve palsy. The diagnosis of aseptic cavernous sinus thrombosis was made and she subsequently made a full recovery.
RESUMO
Background Epilepsy is a chronic neurological disorder which needs proper drug adherence and follow-up care to control the recurrent seizure events as one of the most common reasons for "breakthrough" seizures is nonadherence to antiepileptic drugs. In addition to usual therapeutic management, patients are encouraged to involve in epilepsy self-management by understanding the nature of the disease and its control measures to prevent the complications. Methods A single group experimental design (pretest-posttest) was conducted to evaluate the effect of comprehensive video-assisted teaching program on self-care efficacy and level of knowledge of patients with epilepsy. Data was collected by direct interview with Epilepsy Self-Management Scale and epilepsy knowledge questionnaire. A video-assisted teaching covering all aspects of epilepsy was given on the day of pretest. At the interval of 3 months, the level of drug adherence, self-care, and knowledge level were assessed. Results Majority of the study participants (47.1%) belonged to the age group between 19 and 30 years, 54.3% participants were male, majority of them (70%) had tonic-clonic seizure, and 40% of them reported the onset of seizures as above 20 years. Eighty-seven percent of participants had no family history of seizures or epilepsy. Note that 38.6% of the participants had at least one seizure episode/month. Majority of the caregivers were either parents (41.4%) or spouse (48.6%). The study revealed that, following video-assisted teaching, the proportion of participants with adequate knowledge has increased from 14 to 64.3%. Similarly, the percentage of participants who had good drug adherence increased from 52 to 65% and no participant had poor drug adherence. Participants who had high level of self-care increased from 71.4 to 88.6%. Conclusion To overcome the poor drug adherence-related complications, people with epilepsy are to be personally educated adequately to increase the factual information about the condition and their self-care practices.
RESUMO
BACKGROUND: The people living with epilepsy (PWE) have a higher prevalence of sexual dysfunction (sexual dysfunction) as compared to the general population. About 20-66% of the PWE develop sexual dysfunction. In spite of being so common, it is still an underdiagnosed co-morbidity in epilepsy patients. PURPOSE: To estimate the proportion of sexual dysfunction among PWE, and determine the associated demographic and clinical factors. MATERIAL AND METHODS: This cross-sectional study was conducted at an Epilepsy clinic of a tertiary care hospital located in South India, from March 2017 to May 2017. The PWE satisfying the inclusion criteria were given Changes in Sexual Functioning Questionnaire (CSFQ), Patient Health Questionnaire 9 (PHQ-9) and Generalized Anxiety Disorder-7 questionnaire (GAD-7). The demographic and clinical details were recorded. We estimated the proportion of sexual dysfunction, depression and anxiety and other factors associated with sexual dysfunction. RESULTS: After screening 3225 PWE, 108 patients were recruited. Sixtyfive (60.2%) PWE had sexual dysfunction, 64 (59.3%) had depression and 63 (58.3%) had anxiety. The sexual dysfunction had a significant association with depression (P = 0.01) and anxiety (0.04). Patients receiving sodium valproate had significantly lower rates of sexual dysfunction (P = 0.007). Other factors like seizure type, seizure frequency, enzyme inducer drugs and poly-therapy were not associated with Sexual dysfunction. CONCLUSIONS: We found Sexual dysfunction in 60% of the PWE in our setting. The proportion of depression and anxiety was 59.3% and 58.3% respectively. The depression, anxiety, and low-valproate use were significantly associated with sexual dysfunction.

OBJECTIVE: To study the clinical and imaging profile of patients with new-onset seizures with a presumptive diagnosis of eclampsia. METHODS: This was a cross-sectional study, conducted in a tertiary teaching hospital, on pregnant women presenting with new onset seizures with presumptive diagnosis of eclampsia excluding those with pre-existing neurological conditions. Demographic details, medical and obstetric examination findings were noted. All women underwent neuroimaging within 5â¯days of onset seizures. RESULTS: Presumptive diagnosis of eclampsia was made in 0.7% (nâ¯=â¯186) of women delivering during the time period. Most women (55.4%) presented with seizures in the antenatal period. Neuroimaging is performed in 130 cases and it was found to be abnormal in 45.4% of women (59/130). Most common associated neurological condition was Posterior Reversible Encephalopathy Syndrome in 20% (nâ¯=â¯26) followed by Cerebral Venosus Sinus Thrombosis in 10% (nâ¯=â¯14). All six women with primary intracerebral haemorrhage succumbed to the disease. CONCLUSION: New-onset seizures may be the initial presentation of uncommon and unpredictable complication of pregnancy with serious maternal/ fetal morbidity and mortality. Neuroimaging will help in these patients to avoid the delay or misdiagnosis, resulting in early initiation of specific treatment which will help to improve and optimize outcomes.

New-onset refractory focal epilepsy poses significant challenges to the clinician in the absence of specific diagnostic biomarkers. Differential diagnoses based on imaging may be expanded by a veritable spectrum of peri-ictal imaging findings that may mask the underlying substrate. We report a 13-year-old girl who presented with refractory focal seizures of left parieto-occipital origin with cytotoxic gyral oedema noted over the same region on imaging. Despite an initial negative autoantibody profile, the patient was treated with immunosuppression, followed by serial relapses requiring immune-modulation. Over the next year, her syndrome persisted as focal left posterior cortex epilepsy that necessitated occipital lobectomy, following a relapsing-remitting radiological profile, consistent with peri-ictal MRI changes. Histopathology was inconclusive for any definitive substrate. After a period of quiescence, she developed focal motor seizures of right hemispheric origin with progressive encephalopathy, at which point a repeat cerebrospinal fluid anti-N-methyl-D-aspartate receptor antibody profile returned positive. The patient was managed with steroids and rituximab with a good clinical outcome. We hypothesise that persistent or relapsing-remitting focal gyral oedema in unexplained refractory focal epilepsy mandates consideration of focal encephalitis secondary to autoimmunity, and late appearance of intrathecal auto-antibody synthesis correlates with evolution into a more diffuse disease.

AIM: To study the clinical, electrophysiological and imaging characteristics of patients with unilateral mesial temporal lobe epilepsy (MTLE) with contralateral ictal onset on scalp EEG, viz. 'burned-out hippocampus' syndrome (MTLE-BHS). METHODS: MTLE-BHS was defined as TLE with unilateral hippocampal sclerosis (HS) without any dual pathology on MRI and contralateral ictal onset on scalp EEG, unlike in classical hippocampal sclerosis (HS). Consecutive "MTLE-BHS" patients evaluated at our Centre for Comprehensive Epilepsy Care from January 2005 to July 2014 were studied. Twenty-five cases of classic MTLE-HS operated during the same period were also analyzed for comparison. RESULTS: Seventeen patients were diagnosed to have MTLE-BHS. Mean age of seizure onset was 9.5±7.7years and the mean duration of epilepsy was18.2±7.3years. Epigastric aura was more common in MTLE-HS and fear, secondary generalized seizures and temporal polar changes on MRI were more prevalent in the MTLE-BHS subgroup. In the latter group, five (29%) exhibited seizure semiology and 2 (12%) had interictal discharges discordant to the side of MTS. Eight (47%) patients in the MTLE-BHS sub-group had normal medial temporal volume on Scheltens scale. Eight patients among MTLE-BHS underwent surgery (4 following intracranial monitoring that localized to the side of HS) with Engel class I outcome at 1year follow-up in 6 and Engel class II outcome in 2. CONCLUSION: Attenuation of ipsilateral fast ictal rhythms on scalp EEG as well as neocortical changes are likely to be deterministic factors for MTLE-BHS as opposed to the severity of hippocampal atrophy. Considering good post-operative outcomes, intracranial monitoring for surgical selection is not mandatory in MTLE-BHS despite discordant semiology and ictal onset, in the presence of inter-ictal, functional imaging and neuropsychology data concordant to the side of HS.

Thiopentone sodium is one of the important drugs in the armamentarium for terminating refractory status epilepticus, a neurological emergency. We report a case of thiopentone-related bradycardia during the management of the new onset refractory status epilepticus in a young man, which was circumvented by prophylactic insertion of temporary pacemaker while thiopentone infusion was continued. A systematic approach was employed to manage the status epilepticus, including infusion of thiamine and glucose followed by antiepileptic drugs. The patient was ventilated and infused with lorazepam, phenytoin, sodium valproate, levetiracetam and midazolam followed by thiopentone sodium. With the introduction of thiopentone the seizures could be controlled but the patient developed severe bradycardia and junctional rhythm. The bradycardia disappeared when thiopentone was withdrawn and reappeared when the drug was reintroduced. Propofol infusion was tried with no respite in seizures. Later thiopentone sodium was reintroduced after inserting temporary cardiac pacemaker. Seizure was controlled and patient was weaned off the ventilator.
