Effectiveness of Yoga Intervention in Reducing Felt Stigma in Adults With Epilepsy: A Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: Persons with epilepsy are afflicted with comorbidities such as stigma, anxiety, and depression which have a significant impact on their quality of life. These comorbidities remain largely unaddressed in resource-limited countries. This randomized controlled trial (RCT) aimed to investigate whether yoga and psychoeducation were effective in reducing felt stigma (primary outcome), neuropsychiatric outcomes, and seizure frequency, as compared with sham yoga and psychoeducation in persons with epilepsy. METHODS: This was an assessor-blinded, sham yoga-controlled RCT. Patients clinically diagnosed with epilepsy, aged 18-60 years, and scoring higher than the cutoff score for felt stigma as measured by the Kilifi Stigma Scale (KSS) in our population were randomly assigned to receive either yoga therapy plus psychoeducation (intervention) or sham yoga therapy plus psychoeducation (comparator) for a duration of 3 months. The primary outcome was a significant decrease in felt stigma as compared with the comparator arm as measured by the KSS. Primary and secondary outcomes (seizure frequency, quality of life, anxiety, depression, mindfulness, trait rumination, cognitive impairment, emotion regulation) were assessed at baseline, 3 months, and 6 months. Parametric/nonparametric analysis of covariance and the χ2 test were used to compare the 2 arms. RESULTS: A total of 160 patients were enrolled in the trial. At the end of the follow-up period (6 months), the intervention arm reported significant reduction in felt stigma as compared with the control arm (Cohen's d = 0.23, 95% CI -0.08 to 0.55, p = 0.006). Significantly higher odds of >50% seizure reduction (odds ratio [OR] 4.11, 95% CI 1.34-14.69, p = 0.01) and complete seizure remission (OR 7.4, 95% CI 1.75-55.89, p = 0.005) were also observed in the intervention group. The intervention group showed significant improvement in symptoms of anxiety, cognitive impairment, mindfulness, and quality of life relative to the control group at the end of follow-up period (p < 0.05). DISCUSSION: Yoga can alleviate the burden of epilepsy and improve the overall quality of life in epilepsy by reducing perceived stigma. TRIAL REGISTRATION INFORMATION: Clinical Trials Registry of India (CTRI/2017/04/008385). CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that yoga reduces felt stigma in adult patients with epilepsy.

Yoga nidra practice shows improvement in sleep in patients with chronic insomnia: A randomized controlled trial.

Background Yoga nidra is practised by sages for sleep. The practice is simple to use and has been clearly laid out, but its role in the treatment of chronic insomnia has not been well studied. Methods In this randomized parallel-design study conducted during 2012-16, we enrolled 41 patients with chronic insomnia to receive conventional intervention of cognitive behavioural therapy for insomnia (n=20) or yoga nidra (n=21). Outcome measures were both subjective using a sleep diary and objective using polysomnography (PSG). Salivary cortisol levels were also measured. PSG was done before the intervention in all patients and repeated only in those who volunteered for the same. Results Both interventions showed an improvement in subjective total sleep time (TST), sleep efficiency, wake after sleep onset, reduction in total wake duration and enhancement in subjective sleep quality. Objectively, both the interventions improved TST and total wake duration and increased N1% of TST. Yoga nidra showed marked improvement in N2% and N3% in TST. Salivary cortisol reduced statistically significantly after yoga nidra (p=0.041). Conclusion Improvement of N3 sleep, total wake duration and subjective sleep quality occurred following yoga nidra practice. Yoga nidra practice can be used for treatment of chronic insomnia after supervised practice sessions.

Effect of yoga as add-on therapy in migraine (CONTAIN): A randomized clinical trial.

OBJECTIVE: To evaluate the effectiveness of yoga as an adjuvant to conventional medical management on clinical outcomes in patients with migraine. METHODS: CONTAIN was a prospective, randomized, open-label superiority trial with blinded endpoint assessment carried out at a single tertiary care academic hospital in New Delhi, India. Patients enrolled were aged 18-50 years with a diagnosis of episodic migraine and were randomized into medical and yoga groups (1:1). Randomization was computer-generated with a variable block size and concealed. A predesigned yoga intervention was given for 3 months. Outcomes were recorded by a blinded assessor. The primary endpoint was a decrease in headache frequency, headache intensity, and Headache Impact Test (HIT)-6 score. Secondary outcomes included change in Migraine Disability Assessment (MIDAS) score, pill count, and proportion of headache free patients. RESULTS: Between April 2017 and August 2018, 160 patients with episodic migraine were randomly assigned to medical and yoga groups. A total of 114 patients completed the trial. Baseline measures were comparable except for a higher mean headache frequency in the yoga group. Compared to medical therapy, the yoga group showed a significant mean delta value reduction in headache frequency (delta difference 3.53 [95% confidence interval 2.52-4.54]; p < 0.0001), headache intensity (1.31 [0.60-2.01]; p = 0.0004), HIT score (8.0 [4.78-11.22]; p < 0.0001), MIDAS score (7.85 [4.98-10.97]; p < 0.0001), and pill count (2.28 [1.06-3.51]; p < 0.0003). CONCLUSION: Yoga as an add-on therapy in migraine is superior to medical therapy alone. It may be useful to integrate a cost-effective and safe intervention like yoga into the management of migraine. CLINICALTRIALSGOV IDENTIFIER: CTRI/2017/03/008041. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for patients with episodic migraine, yoga as adjuvant to medical therapy improves headache frequency, intensity, impact, and disability.

Cognitive Improvement with Glutathione Supplement in Alzheimer's Disease: A Way Forward.

Alzheimer's disease (AD) is a devastating neurodegenerative disorder affecting millions of people worldwide. The actual cause of AD is still unknown. Oxidative stress is believed to be important player in AD pathology. Glutathione (GSH) is a major antioxidant, and it is already known that GSH is depleted significantly in the hippocampal regions in mild cognitive impairment (MCI) and AD patients compared to healthy old subjects. Hence there is a serious discussion to improve the brain GSH level by supplementation. This editorial highlights the need for GSH supplementation for the cognitive enhancement in MCI and AD.

Endoscope-assisted (with robotic guidance and using a hybrid technique) interhemispheric transcallosal hemispherotomy: a comparative study with open hemispherotomy to evaluate efficacy, complications, and outcome.

OBJECTIVEEndoscope-assisted hemispherotomy (EH) has emerged as a good alternative option for hemispheric pathologies with drug-resistant epilepsy.METHODSThis was a prospective observational study. Parameters measured included primary outcome measures (frequency, severity of seizures) and secondary outcomes (cognition, behavior, and quality of life). Blood loss, operating time, complications, and hospital stay were also taken into account. A comparison was made between the open hemispherotomy (OH) and endoscopic techniques performed by the senior author.RESULTSOf 59 cases (42 males), 27 underwent OH (8 periinsular, the rest vertical) and 32 received EH. The mean age was 8.65 ± 5.41 years (EH: 8.6 ± 5.3 years; OH: 8.6 ± 5.7 years). Seizure frequency per day was 7 ± 5.9 (EH: 7.3 ± 4.6; OH: 15.0 ± 6.2). Duration of disease (years since first episode) was 3.92 ± 1.24 years (EH: 5.2 ± 4.3; OH: 5.8 ± 4.5 years). Number of antiepileptic drugs per patient was 3.9 ± 1.2 (EH: 4.2 ± 1.2; OH: 3.8 ± 0.98). Values for the foregoing variables are expressed as the mean ± SD. Pathologies included the following: postinfarct encephalomalacia in 19 (EH: 11); Rasmussen's syndrome in 14 (EH: 7); hemimegalencephaly in 12 (EH: 7); hemispheric cortical dysplasia in 7 (EH: 4); postencephalitis sequelae in 6 (EH: 2); and Sturge-Weber syndrome in 1 (EH: 1). The mean follow-up was 40.16 ± 17.3 months. Thirty-nine of 49 (79.6%) had favorable outcomes (International League Against Epilepsy class I and II): in EH the total was 19/23 (82.6%) and in OH it was 20/26 (76.9%). There was no difference in the primary outcome between EH and OH (p = 0.15). Significant improvement was seen in the behavioral/quality of life performance, but not in IQ scores in both EH and OH (p < 0.01, no intergroup difference). Blood loss (p = 0.02) and hospital stay (p = 0.049) were less in EH.CONCLUSIONSEH was as effective as the open procedure in terms of primary and secondary outcomes. It also resulted in less blood loss and a shorter postoperative hospital stay.

Clinical spectrum of psychogenic non epileptic seizures in children; an observational study.

PURPOSE: The current study was designed to analyze the clinical spectrum of Psychogenic non-epileptic seizures (PNES) in children. METHODS: Children aged 6-16years with clinically suspected PNES, confirmed by short-term VEEG (STVEEG{video electroencephalogram}) and induction were classified as per Seneviratne classification. Stressors, associated co morbidities, Verbal IQ (Intelligence Quotient) and behavioral abnormalities were assessed using HTP(House tree person) test, DSM IV (Diagnostic and statistical manual of mental disorders) TR criteria, MISIC (Malin intelligence scale for Indian children) and CBCL (Child behaviour checklist). RESULTS: Eighty children with PNES {45 boys; mean age: 10.5 (±1.6) years} were enrolled. Median delay in diagnosis was 5 months {IQR(interquartile range)- 0.5 to 48 months}) and 45% patients were already on AEDs (antiepileptic drugs). Commonest semiology was dialeptic (42.5%), followed by mixed (28.8%), motor (15%) and nonepileptic aura (13.8%). Family stressors were the commonest followed by school related issues. The most common psychiatric comorbidity was adjustment disorder. Somatic complaints were observed in 50% children. CONCLUSIONS: Dialeptic PNES is commonest in children. In resource constrained settings, STVEEG along with induction is a reliable method to diagnose PNES. A comprehensive assessment protocol (including assessment of stressors) is needed for holistic management of pediatric PNES.

Radiosurgery versus open surgery for mesial temporal lobe epilepsy: The randomized, controlled ROSE trial.

OBJECTIVE: To compare stereotactic radiosurgery (SRS) versus anterior temporal lobectomy (ATL) for patients with pharmacoresistant unilateral mesial temporal lobe epilepsy (MTLE). METHODS: This randomized, single-blinded, controlled trial recruited adults eligible for open surgery among 14 centers in the USA, UK, and India. Treatment was either SRS at 24 Gy to the 50% isodose targeting mesial structures, or standardized ATL. Outcomes were seizure remission (absence of disabling seizures between 25 and 36 months), verbal memory (VM), and quality of life (QOL) at 36-month follow-up. RESULTS: A total of 58 patients (31 in SRS, 27 in ATL) were treated. Sixteen (52%) SRS and 21 (78%) ATL patients achieved seizure remission (difference between ATL and SRS = 26%, upper 1-sided 95% confidence interval = 46%, P value at the 15% noninferiority margin = .82). Mean VM changes from baseline for 21 English-speaking, dominant-hemisphere patients did not differ between groups; consistent worsening occurred in 36% of SRS and 57% of ATL patients. QOL improved with seizure remission. Adverse events were anticipated cerebral edema and related symptoms for some SRS patients, and cerebritis, subdural hematoma, and others for ATL patients. SIGNIFICANCE: These data suggest that ATL has an advantage over SRS in terms of proportion of seizure remission, and both SRS and ATL appear to have effectiveness and reasonable safety as treatments for MTLE. SRS is an alternative to ATL for patients with contraindications for or with reluctance to undergo open surgery.

Pharmacodynamic and pharmacokinetic interaction of Panchagavya Ghrita with phenytoin and carbamazepine in maximal electroshock induced seizures in rats.

INTRODUCTION: Traditionally, Panchagavya Ghrita (PG) has been used for the management of epilepsy, anxiety, fever and jaundice. It consists of five components of cow products namely, cow milk, clarified butter from cow milk, cow urine, curd from cow milk, and cow dung juice. AIM: To evaluate the effect of PG in maximal electroshock (MES) induced seizures model and its pharmacodynamic and pharmacokinetic interaction with phenytoin (PHT) and carbamazepine (CBZ) in rats. MATERIALS AND METHODS: Male Wistar rats were administered PG 500, 1000, 2000, and 4000 mg/kg orally for 7 days and seizures were induced by MES. For interaction studies, PG (4000 mg/kg) was administered along with a sub-therapeutic dose of PHT (20 mg/kg, p.o.) and CBZ (10 mg/kg, p.o.). Behavioral parameters were assessed. Oxidative stress markers and serum levels of PHT and CBZ were estimated. RESULTS: Tonic hind limb extension, cognitive impairment, and oxidative stress produced by MES were reversed by PG (4000 mg/kg). Co-administration of PG (4000 mg/kg) with a sub-therapeutic dose of PHT and CBZ potentiated antiepileptic effect and ameliorated cognitive impairment as well as oxidative stress. Although, there was a slight increase in serum levels of PHT and CBZ on co-administration with PG, it was statistically insignificant. CONCLUSION: Co-administration of PG with low doses of PHT and CBZ caused complete seizure protection. This suggests the potential of PG as an adjunct in epilepsy with improved efficacy and tolerability.

Seizures in patients with idiopathic hypoparathyroidism: effect of antiepileptic drug withdrawal on recurrence of seizures and serum calcium control.

OBJECTIVE: There is limited information on seizures in patients with idiopathic hypoparathyroidism (IH). We assessed seizure characteristics at presentation, subclinical seizures during follow-up, and the effect of antiepileptic drug (AED) withdrawal in IH patients. DESIGNS AND METHODS: Seizure characteristics were assessed in 70 patients with IH attending endocrine clinic. Provoked electroencephalography (EEG) was performed for subclinical seizures in 44 of them. AEDs were withdrawn using strict criteria, i.e. i) no seizure during past 2 years, ii) normal EEG, iii) serum total calcium ≥1.8 mmol/l, and iv) feasibility to follow-up regularly after AED withdrawal for at least 9 months (n=14). The effects of AED withdrawal on seizures and serum total calcium were assessed. RESULTS: Seizures were present in 64.3% of patients, generalized tonic-clonic in 86.7%, and treated with phenytoin (46.7%), valproate (40%), and carbamazepine (26.7%). Most (69/70) patients were seizure-free during the follow-up of 6.6±4.5 years. Ten of 14 (71.4%) patients were successfully withdrawn from AED and remained seizure free during the follow-up period of 13.5±2.4 months (range 9-18). AEDs were restarted because of the recurrence of seizures (n=3) and poor compliance with calcium/vitamin D (n=1). The mean serum total calcium increased from 1.9±0.19 to 2.1±0.14 mmol/l after AED withdrawal (P=0.004). CONCLUSION: Seizures were present in 64.3% of patients with IH and they responded to AED and calcium/1-α-(OH)D during the follow-up. With strict eligibility criteria, it was possible to withdraw AED in 71% of patients with IH. Serum total calcium improved significantly after AED withdrawal.

Determination of efficacy of reflexology in managing patients with diabetic neuropathy: a randomized controlled clinical trial.

Background. The restricted usage of existing pharmacological methods which do not seem to provide the treatment of diabetic neuropathy may lead to exploring the efficacy of a complementary therapy. In this context, this paper was devoted to evaluate the efficacy of foot reflexology. This health science works on the hypothesis that the dysfunctional states of body parts could be identified by observing certain skin features and be rectified by stimulating certain specific areas mapped on feet. Method. Subjects (N = 58) with diagnosed diabetic neuropathy were randomly distributed into reflexology and control groups in which both group patients were treated with ongoing pharmacological drugs. Reflexology group patients were additionally treated holistically with the hypothesis that this therapy would bring homeostasis among body organ functions. This was a caregiver-based study with a follow-up period of 6 months. The outcome measures were pain reduction, glycemic control, nerve conductivity, and thermal and vibration sensitivities. The skin features leading to the detection of the abnormal functional states of body parts were also recorded and analyzed. Results. Reflexology group showed more improvements in all outcome measures than those of control subjects with statistical significance. Conclusion. This study exhibited the efficient utility of reflexology therapy integrated with conventional medicines in managing diabetic neuropathy.

Role of reflexology and antiepileptic drugs in managing intractable epilepsy--a randomized controlled trial.

BACKGROUND: This report is based on the results of a randomized parallel controlled trial conducted to determine the efficacy of reflexology therapy in managing intractable epilepsy. METHODS: Subjects who failed epilepsy surgery or were not candidates for epilepsy surgery or were non-responders of antiepileptic drugs (AEDs) took part in this study. The trial was completed by 77 subjects randomly assigned to 2 arms: control (AEDs) and reflexology (AEDs + reflexology therapy). The hypothesis was that hand reflexology therapy could produce results similar to those of vagus nerve stimulation, and foot reflexology therapy could maintain homeostasis in the functional status of individual body parts. Reflexology therapy was applied by family members. The follow-up period was 1.5 years. Quality of life in epilepsy patients was assessed with the QOLIE-31 instrument. RESULTS: In the reflexology group, the median baseline seizure frequency decreased from 9.5 (range 2-120) to 2 (range 0-110) with statistical significance (p < 0.001). In the control arm, the decrease was less than 25% with a baseline value of 16 (range 2-150). The pretherapy QOLIE-31 scores in the control group and the reflexology group were 41.05 ± 7 and 43.6 ± 8, respectively. Posttherapy data were 49.07 ± 6 and 65.4 ± 9, respectively (p < 0.002). The reflexology method allowed detection of knee pain in 85% of the reflexology group patients (p < 0.001), and 85.3% of patients derived 81% relief from it (p < 0.001). 4 reflexology group patients reported nausea/vomiting (n = 1), change in voice (n = 2), and hoarseness (n = 1). CONCLUSION: Reflexology therapy together with AEDs may help reducing seizure frequency and improving quality of life in individuals with epilepsy.

Effect of Anacyclus pyrethrum on pentylenetetrazole-induced kindling, spatial memory, oxidative stress and rho-kinase II expression in mice.

Anacyclus pyrethrum (A. pyrethrum) has been reported to exhibit anticonvulsant activity. In the present study, the effect of hydro-alcoholic extract of A. pyrethrum root (HEAP) on pentylenetetrazole (PTZ) induced kindling, spatial memory, oxidative stress and rho kinase (ROCK II) was assessed. Male albino mice (25-30 g) were used in the study. PTZ (35 mg/kg, i.p. on alternate days) was injected to induce kindling and PTZ (70 mg/kg, i.p) challenge was given 7 days post-kindling. HEAP was administered orally daily in the doses of 100, 250 and 500 mg/kg along with PTZ injections during the kindling process and continued till PTZ challenge post kindling. Spatial memory was assessed using Morris water maze test. Oxidative stress parameters [malondialdehyde (MDA) and reduced glutathione (GSH)] and ROCK II expression were estimated in whole brain at the end of the study. Pre-treatment with HEAP (250 and 500 mg/kg) showed significant increase in the myoclonic jerk latency and delay in the development of kindling. A significant decrease in mortality was observed at higher doses of HEAP (250 and 500 mg/kg). Pre-treatment with HEAP significantly increased the number of platform crossings and decreased the escape latency, as opposed to the PTZ group, thus showing protection against memory deficit. HEAP pre-treatment also attenuated the oxidative stress induced by PTZ kindling. PTZ induced kindling increased the ROCK II expression whereas, HEAP pre-treatment attenuated the increase in ROCK II expression. To conclude, HEAP pre-treatment showed antiepileptic effect and also showed protection against cognitive impairment by decreasing oxidative stress and ROCK II expression in PTZ kindled mice.

Interaction profile of Zizyphus jujuba with phenytoin, phenobarbitone, and carbamazepine in maximal electroshock-induced seizures in rats.

The antiepileptic effect of hydroalcoholic extract of Zizyphus jujuba (HEZJ) in experimental seizures was demonstrated earlier. The present study aimed to evaluate the pharmacokinetic and pharmacodynamic interactions of HEZJ with phenytoin (PHT), phenobarbitone (PB), and carbamazepine (CBZ) in maximal electroshock (MES)-induced seizures in male Wistar rats. Maximal electroshock (70 mA, 9 ms pulse width, 0.2 s) was used to induce seizures. Blood samples were collected at two time points for estimation of serum PHT, PB, and CBZ levels using high-pressure liquid chromatography (HPLC). Co-administration of HEZJ with the sub-therapeutic doses of PHT, PB, and CBZ exhibited 66.7, 66.7, and 50.0% protection against tonic hind limb extension as compared to 33.3, 33.3, and 50% protection respectively, in the groups treated with PHT, PB, and CBZ alone in their sub-therapeutic doses. Co-administration of HEZJ with the sub-therapeutic doses of these antiepileptic drugs (AEDs) showed significant improvement in cognitive functions as compared to MES group as well as these AEDs alone. A significant increase in glutathione levels and decrease in malondialdehyde levels were observed with pretreatment of HEZJ with the sub-therapeutic doses of these AEDs. Co-administration of HEZJ with PHT, PB, and CBZ did not cause any significant changes in the serum concentrations of these AEDs. The results of the present study indicate that the co-administration of HEZJ with sub-therapeutic doses of PHT and PB potentiated the antiepileptic effect of PHT and PB in MES-induced seizures with no change found in the antiepileptic effect of CBZ.
