Cross-cultural application of the international classification of cognitive disorders in epilepsy cognitive phenotypes in people with temporal lobe epilepsy in India.

OBJECTIVE: Efforts to understand the global variability in cognitive profiles in patients with epilepsy have been stymied by the lack of a standardized diagnostic system. This study examined the cross-cultural applicability of the International Classification of Cognitive Disorders in Epilepsy (IC-CoDE) in a cohort of patients with temporal lobe epilepsy (TLE) in India that was diverse in language, education, and cultural background. METHODS: A cohort of 548 adults with TLE from Mumbai completed a presurgical comprehensive neuropsychological evaluation. The IC-CoDE taxonomy was applied to derive cognitive phenotypes in the sample. Analyses of variance were conducted to examine differences in demographic and clinical characteristics across the phenotypes, and chi-squared tests were used to determine whether the phenotype distribution differed between the Mumbai sample and published data from a multicenter US sample. RESULTS: Using the IC-CoDE criteria, 47% of our cohort showed an intact cognitive profile, 31% a single-domain impairment, 16% a bidomain impairment, and 6% a generalized impairment profile. The distribution of cognitive phenotypes was similar between the Indian and US cohorts for the intact and bidomain phenotypes, but differed for the single and generalized domains. There was a larger proportion of patients with single-domain impairment in the Indian cohort and a larger proportion with generalized impairment in the US cohort. Among patients with single-domain impairment, a greater proportion exhibited memory impairment in the Indian cohort, whereas a greater proportion showed language impairment in the US sample, likely reflecting differences in language administration procedures and sample characteristics including a higher rate of mesial temporal sclerosis in the Indian sample. SIGNIFICANCE: Our results demonstrate the applicability of IC-CoDE in a group of culturally and linguistically diverse patients from India. This approach enhances our understanding of cognitive variability across cultures and enables harmonized and inclusive research into the neuropsychological aspects of epilepsy.

MoCA in five Indian languages: A brief screening tool to diagnose dementia and MCI in a linguistically diverse setting.

INTRODUCTION AND OBJECTIVES: Early dementia diagnosis in low and middle-income countries (LMIC) is challenging due to limited availability of brief, culturally appropriate, and psychometrically validated tests. Montreal Cognitive Assessment (MoCA) is one of the most widely used cognitive screening tests in primary and secondary care globally. In the current study, we adapted and validated MoCA in five Indian languages (Hindi, Bengali, Telugu, Kannada, and Malayalam) and determined the optimal cut-off points that correspond to screening for clinical diagnosis of dementia and MCI. METHODS: A systematic process of adaptation and modifications of MoCA was fulfilled. A total of 446 participants: 214 controls, 102 dementia, and 130 MCI were recruited across six centers. RESULTS: Across five languages, the area under the curve for diagnosis of dementia varied from 0.89 to 0.98 and MCI varied from 0.73 to 0.96. The sensitivity, specificity and optimum cut-off scores were established separately for five Indian languages. CONCLUSIONS: The Indian adapted MoCA is standardized and validated in five Indian languages for early diagnosis of dementia and MCI in a linguistically and culturally diverse population.

Picture-naming test for a linguistically diverse population with cognitive impairment and dementia.

BACKGROUND: Picture-naming tests (PNTs) evaluate linguistic impairment in dementia due to semantic memory impairment, impaired lexical retrieval or perceptual deficits. They also assess the decline in naming impairment at various stages of dementia and mild cognitive impairment (MCI) that occurs due to progressive cognitive impairment. With the increasing numbers of people with dementia globally, it is necessary to have validated naming tests and norms that are culturally and linguistically appropriate. AIMS: In this cross-sectional study we harmonized a set of 30 images applicable to the Indian context across five languages and investigated the picture-naming performance in patients with MCI and dementia. METHODS & PROCEDURES: A multidisciplinary expert group formed by the Indian Council of Medical Research (ICMR) collaborated towards developing and adapting a picture naming test (PNT) known as the ICMR-PNT in five Indian languages: Hindi, Bengali, Telugu, Kannada and Malayalam. Based on cross-cultural adaptation guidelines and item-wise factor analysis and correlations established separately across five languages, the final version of the ICMR-PNT test was developed. A total of 368 controls, 123 dementia and 128 MCI patients were recruited for the study. Psychometric properties of the adapted version of the ICMR-PNT were examined, and sensitivity and specificity were examined. OUTCOMES & RESULTS: The ICMR-PNT scores in all languages combined were higher in controls compared with patients with dementia and MCI (F2, 615 = 139.85; p < 0.001). Furthermore, PNT scores for MCI was higher in comparison with patients with dementia in all languages combined (p < 0.001). The area under the curve across the five languages ranged from 0.81 to 1.00 for detecting dementia. There was a negative correlation between Clinical Dementia Rating (CDR) and ICMR-PNT scores and a positive correlation between Addenbrooke's Cognitive Examination-III (ACE-III) and ICMR-PNT scores in control and patient groups. CONCLUSIONS & IMPLICATIONS: The ICMR-PNT was developed by following cross-cultural adaptation guidelines and establishing correlations using item-wise factor analysis across five languages. This adapted PNT was found to be a reliable tool when assessing naming abilities effectively in mild to moderate dementia in a linguistically diverse context. WHAT THIS PAPER ADDS: What is already known on this subject Picture-naming evaluates language impairment linked to naming difficulties due to semantic memory, lexical retrieval or perceptual disturbances. As a result, picture naming tests (PNTs) play an important role in the diagnosis of dementia. In a heterogeneous population such as India, there is a need for a common PNT that can be used across the wide range of languages. What this study adds to existing knowledge PNTs such as the Boston Naming Test (BNT) were developed for the educated, mostly English-speaking, Western populations and are not appropriate for use in an Indian context. To overcome this challenge, a PNT was harmonized in five Indian languages (Hindi, Bengali, Telugu, Kannada and Malayalam) and we report the patterns of naming difficulty in patients with MCI and dementia. The ICMR-PNT demonstrated good diagnostic accuracy when distinguishing patients with mild to moderate dementia from cognitively normal individuals. What are the potential or actual clinical implications of this work? With the growing number of persons suffering from Alzheimer's disease and other forms of dementia around the world, its critical to have culturally and linguistically relevant naming tests and diagnosis. This validated ICMR-PNT can be used widely as a clinical tool to diagnose dementia and harmonize research efforts across diverse populations.

Validation of Indian Council of Medical Research Neurocognitive Tool Box in Diagnosis of Mild Cognitive Impairment in India: Lessons from a Harmonization Process in a Linguistically Diverse Society.

BACKGROUND/AIMS: In a linguistically diverse country such as India, challenges remain with regard to diagnosis of early cognitive decline among the elderly, with no prior attempts made to simultaneously validate a comprehensive battery of tests across domains in multiple languages. This study aimed to determine the utility of the Indian Council of Medical Research-Neurocognitive Tool Box (ICMR-NCTB) in the diagnosis of mild cognitive impairment (MCI) and its vascular subtype (VaMCI) in 5 Indian languages. METHODS: Literate subjects from 5 centers across the country were recruited using a uniform process, and all subjects were classified based on clinical evaluations and a gold standard test protocol into normal cognition, MCI, and VaMCI. Following adaptation and harmonization of the ICMR-NCTB across 5 different Indian languages into a composite Z score, its test performance against standards, including sensitivity and specificity of the instrument as well as of its subcomponents in diagnosis of MCI, was evaluated in age and education unmatched and matched groups. RESULTS: Variability in sensitivity-specificity estimates was noted between languages when a total of 991 controls and 205 patients with MCI (157 MCI and 48 VaMCI) were compared due to a significant impact of age, education, and language. Data from a total of 506 controls, 144 patients with MCI, and 46 patients with VaMCI who were age- and education-matched were compared. Post hoc analysis after correction for multiple comparisons revealed better performance in controls relative to all-cause MCI. An optimum composite Z-score of -0.541 achieved a sensitivity of 81.1% and a specificity of 88.8% for diagnosis of all-cause MCI, with a high specificity for diagnosis of VaMCI. Using combinations of multiple-domain 2 test subcomponents retained a sensitivity and specificity of >80% for diagnosis of MCI. CONCLUSIONS: The ICMR-NCTB is a "first of its kind" approach at harmonizing neuropsychological tests across 5 Indian languages for the diagnosis of MCI due to vascular and other etiologies. Utilizing multiple-domain subcomponents also retains the validity of this instrument, making it a valuable tool in MCI research in multilingual settings.

Standardising Dementia Diagnosis Across Linguistic and Educational Diversity: Study Design of the Indian Council of Medical Research-Neurocognitive Tool Box (ICMR-NCTB).

OBJECTIVES: While the burden of dementia is increasing in low- and middle-income countries, there is a low rate of diagnosis and paucity of research in these regions. A major challenge to study dementia is the limited availability of standardised diagnostic tools for use in populations with linguistic and educational diversity. The objectives of the study were to develop a standardised and comprehensive neurocognitive test battery to diagnose dementia and mild cognitive impairment (MCI) due to varied etiologies, across different languages and educational levels in India, to facilitate research efforts in diverse settings. METHODS: A multidisciplinary expert group formed by Indian Council of Medical Research (ICMR) collaborated towards adapting and validating a neurocognitive test battery, that is, the ICMR Neurocognitive Tool Box (ICMR-NCTB) in five Indian languages (Hindi, Bengali, Telugu, Kannada, and Malayalam), for illiterates and literates, to standardise diagnosis of dementia and MCI in India. RESULTS: Following a review of existing international and national efforts at standardising dementia diagnosis, the ICMR-NCTB was developed and adapted to the Indian setting of sociolinguistic diversity. The battery consisted of tests of cognition, behaviour, and functional activities. A uniform protocol for diagnosis of normal cognition, MCI, and dementia due to neurodegenerative diseases and stroke was followed in six centres. A systematic plan for validating the ICMR-NCTB and establishing cut-off values in a diverse multicentric cohort was developed. CONCLUSIONS: A key outcome was the development of a comprehensive diagnostic tool for diagnosis of dementia and MCI due to varied etiologies, in the diverse socio-demographic setting of India.

Imaging & neuropsychological changes in brain with spiritual practice: A pilot study.

BACKGROUND & OBJECTIVES: Some studies have systematically assessed the effects of spiritual practice (SP) on the brain using combined neuropsychological testing and functional imaging. The objective of the present study was to compare imaging and neuropsychological changes in healthy individuals after SP and those with only physical exercise. METHODS: Healthy adult male volunteers, aged 25-45 yr were randomized into two groups. Group 1 (SP group) underwent the SP and group 2 (controls) did brisk walk for 30 min daily. Detailed neuropsychological evaluation, resting-state functional magnetic resonance imaging (fMRI) and brain 99mTc ethyl cysteinate dimer single-photon emission computed tomography (SPECT) were carried out for both groups before and three months after intervention. RESULTS: Post-intervention, resting state fMRI showed increased connections of left precuneus (in the posterior cingulate cortex area of default mode network) in group 1 and increased left frontal connections in group 2. The neuropsychological tests showed significant improvement in 'Speed of Processing' (Digit Symbol Test) in group 1 and in Focused Attention (Trail Making A) in group 2. The SPECT data in group 1 showed significant improvement in perfusion of the frontal areas, with relatively lesser improvement in parietal areas. Group 2 showed significant improvement in perfusion predominantly in parietal areas, as compared to frontal areas. In addition, significantly improved mood was reported by group 1 and not by group 2. INTERPRETATION & CONCLUSIONS: This pilot study shows important functional imaging and neuropsychological changes in the brain with SP.

Comorbidities of epilepsy.

In epilepsy management, control of seizures is the prime objective. However, the quality of life is affected by comorbid conditions that include the neurological, neuropsychiatric, and neurobehavioural disorders. These are not only reactive processes to a chronic condition but also have a bidirectional relationship, sharing common underlying pathogenesis. This article besides addressing these issues also explores the therapeutic management. A systematic search of PubMed from Jan 2006 to August 2016 was undertaken using the terms "comorbidities" and "epilepsy." In addition, articles specifically from India and other original papers were selected based on relevance. In this review, the neuropsychiatric, neurobehavioral (mood disorders, behaviour issues, attention deficits, psychosis), and neurologic [cognitive impairment, migraine, SUDEP-Sudden unexpected death in epilepsy (SUDEP)] comorbidities are covered in relation to epilepsy and its treatment. The incidental disorders such as hypertension, diabetes, and cancer that are mentioned in some reports have not been addressed here. Comorbidities in epilepsy are common but poorly understood and often remain unaddressed. The prevalence of comorbid conditions is considerably higher in epilepsy than seen in the general population and other chronic conditions. There is a wide spectrum of secondary disorders that have a marked impact and significantly increase the burden of the primary epilepsy condition. There is a need to acknowledge, screen, and intervene early in newly diagnosed cases for the optimal management of epilepsy.

The dilemma of arranged marriages in people with epilepsy. An expert group appraisal.

INTRODUCTION: Matrimony remains a challenging psychosocial problem confronting people with epilepsy (PWE). People with epilepsy are less likely to marry; however, their marital prospects are most seriously compromised in arranged marriages. AIMS: The aim of this study was to document marital prospects and outcomes in PWE going through arranged marriage and to propose optimal practices for counseling PWE contemplating arranged marriage. METHODS: A MEDLINE search and literature review were conducted, followed by a cross-disciplinary meeting of experts to generate consensus. RESULTS: People with epilepsy experience high levels of felt and enacted stigma in arranged marriages, but the repercussions are heavily biased against women. Hiding epilepsy is common during marital negotiations but may be associated with poor medication adherence, reduced physician visits, and poor marital outcome. Although divorce rates are generally insubstantial in PWE, divorce rates appear to be higher in PWE undergoing arranged marriages. In these marriages, hiding epilepsy during marital negotiations is a risk factor for divorce. CONCLUSIONS: In communities in which arranged marriages are common, physicians caring for PWE are best-equipped to counsel them about their marital prospects. Marital plans and aspirations should be discussed with the family of the person with epilepsy in a timely and proactive manner. The benefits of disclosing epilepsy during marital negotiations should be underscored.

Naming assessment in bilinguals for epilepsy surgery-adaptation and standardization of Boston Naming Test in India.

PURPOSE: Naming difficulty is associated with temporal lobe epilepsy and a decline in naming ability is reported following dominant temporal lobe resections. The Boston Naming Test (BNT) is the most frequently used test for assessing naming ability. Evaluating naming ability in bilingual/multilingual populations is a challenge when participants are restricted to responding in one language. The study aimed to adapt and standardize the BNT as a valid clinical tool for evaluating bilingual/multilingual people undergoing epilepsy surgery in urban India. RESULTS: Culture-appropriate adaptations were done, and participants were allowed to respond in any language. Data from 197 participants showed a strong education effect. The adaptation showed strong internal consistency, reliability, construct validity, and high sensitivity to left temporal lobe epilepsy performance. CONCLUSIONS: The adapted version that allowed for flexible use of more than one language is a useful clinical tool for evaluating bilingual people undergoing epilepsy surgery.

Neurocognitive and neurobehavioral disabilities in Epilepsy with Electrical Status Epilepticus in slow sleep (ESES) and related syndromes.

AIM: The aims of this study were to assess the cognitive and behavioral problems of patients with Epilepsy with Electrical Status Epilepticus in slow sleep (ESES) and related syndromes and to review their EEG (electroencephalography) findings and treatment options. RESULTS: Fourteen patients with ESES were evaluated and treated in 2010. Nine children had continuous spike and wave during slow-wave sleep (CSWS)/ESES syndrome, 3 had Atypical BECTS (benign epilepsy with centrotemporal spikes), 1 had Opercular syndrome, and 1 had Landau-Kleffner syndrome. The duration of ESES ranged from 6 to 52 months. Eleven (91%) children had behavioral issues, most prominent being hyperactivity. Seven of the 13 children (53%) showed evidence of borderline to moderate cognitive impairment. A total of 28 EEG findings of ESES were analyzed for SWI (spike-wave index). Antiepileptic drugs received by the patients included valproate, clobazam, levetiracetam, and others. Eleven patients had been treated with oral steroids and it was found to be efficacious in seven (63%). CONCLUSION: Disabilities caused by ESES affect multiple domains. Patients with an SWI>50% should be followed up frequently with neuropsychological assessments. Steroids appear to be effective, although there is a need to standardize the dose and duration of treatment.

Challenges for low middle-income people with epilepsy during the COVID-19 pandemic: Lessons learnt, call for action.

OBJECTIVE: The COVID-19 pandemic impacted the care of people with epilepsy (PWE). Several online surveys were conducted but there is limited data regarding the impact on low-income PWE from lower-middle income countries (LMICs) who have no access or ability to answer online surveys. The purpose of this interview was to understand the challenges faced by low-income PWE during the lockdown phase of the pandemic. METHOD: PWE visiting the epilepsy specialty outpatient department of a tertiary referral government hospital to avail of subsidized services were interviewed. In the interview, they discussed challenges in obtaining medical care, the impact on wellbeing, employment, and vaccination status during the lockdown phase of the pandemic. RESULTS: Out of the 214 PWE interviewed, 20.6% had increased seizure frequency, 28.9% did not have access to medication mainly due to travel restrictions, 30.5% reported lack of availability of medication and 50% were not able to afford the medication mainly due to loss of income. 51% were unable to have follow-up consultations. 36% reported worsening of mood and some reported impact on other aspects of wellbeing. The impact on wellbeing was significantly associated with an increase in seizure frequency (P < .05). The study revealed hesitation related to vaccines in the majority and expectations of financial support by the government and assistance for procuring medication. There was a lack of awareness about telemedicine services and the same was not adequately offered by government hospitals. SIGNIFICANCE: The study underscores the need to learn lessons from the challenging experiences of low-income PWE and create an action plan for the future to address the issues of lack of affordability of medical care and access to telemedicine. It is critical that the care of the marginalized, underrepresented PWE from lower-middle income countries is not neglected during a pandemic.

Tele-Neurorehabilitation During the COVID-19 Pandemic: Implications for Practice in Low- and Middle-Income Countries.

The importance of neurorehabilitation services for people with disabilities is getting well-recognized in low- and middle-income countries (LMICs) recently. However, accessibility to the same has remained the most significant challenge, in these contexts. This is especially because of the non-availability of trained specialists and the availability of neurorehabilitation centers only in urban cities owned predominantly by private healthcare organizations. In the current COVID-19 pandemic, the members of the Task Force for research at the Indian Federation of Neurorehabilitation (IFNR) reviewed the context for tele-neurorehabilitation (TNR) and have provided the contemporary implications for practicing TNR during COVID-19 for people with neurological disabilities (PWNDs) in LMICs. Neurorehabilitation is a science that is driven by rigorous research-based evidence. The current pandemic implies the need for systematically developed TNR interventions that is evaluated for its feasibility and acceptability and that is informed by available evidence from LMICs. Given the lack of organized systems in place for the provision of neurorehabilitation services in general, there needs to be sufficient budgetary allocations and a sector-wide approach to developing policies and systems for the provision of TNR services for PWNDs. The pandemic situation provides an opportunity to optimize the technological innovations in health and scale up these innovations to meet the growing burden of neurological disability in LMICs. Thus, this immense opportunity must be tapped to build capacity for safe and effective TNR services provision for PWNDs in these settings.

Consensus Statement on Neurorehabilitation during COVID-19 Times: Expert Group on Behalf of the Indian Federation of Neurorehabilitation (IFNR).

The COVID19 pandemic in India is causing significant morbidity and disruptions of healthcare delivery. The rapidly escalating contagion is straining our public health system, which is already under pressure due to a shortage of infrastructure and inadequate workforce. Neuro rehabilitation services that are still in its infancy in our country have been significantly interrupted in the last six months. An expert group from Indian Federation of Neurorehabilitation (IFNR) have formulated the guidelines and consensus recommendations for Neurologists, Physiatrists, and Therapists managing neurological disabilities during COVID 19. The aim of this consensus paper is to sensitize the clinicians and therapists about maintaining the continuum of care and rehabilitation needs of Covid patients as well as non Covid patients with neurological disorders during the ongoing COVID 19 pandemic.

Current practices in epilepsy monitoring units (EMU) in India.

AIM: As an initial step to develop guidelines for epilepsy monitoring units (EMUs) appropriate for developing countries, we inquired the existing practices in EMUs in India. METHODS: After checking for the content and face validity as well for clarity, we sent a 52-item online non-anonymized questionnaire to all the 52 EMUs in India. RESULTS: The questionnaire was completed by 51 of the 52 EMUs (98% response rate). The majority of the EMUs are located in major cities and 51% are located in non-governmental corporate hospitals. There are total of 122 prolonged video-EEG monitoring (PVEM) beds in India and 70% EMUs have ≤2 beds. Approximately two-thirds of the EMUs have defined protocols for pre-procedure consent and risk assessment, management of seizure clusters and status epilepticus, continuous observation of patients, and peri­ictal testing. Only one-third of the EMUs have protocols for management of post-ictal psychosis, anti-suffocation pillows, and protected environment within bathrooms. The waiting period for PVEM is more (49.9 ± 101 vs. 4.9 ± 10.9 days; p = 0.04) and mean cost for 3-day PVEM is less (INR 8311 ± 9021 vs. 30,371 ± 17,563; p <0.0001) in public as compared to private hospitals. There was a negative correlation between cost of PVEM and the waiting period (r=-0.386; p = 0.01). Safety practices are similar in public and private hospitals. CONCLUSIONS: Although practices in EMUs in India vary widely, they are comparable to those in developed countries. India has severe shortage of EMUs and long waiting lists for affordable PVEM.

Validation of ICMR Neurocognitive Toolbox for Dementia in the Linguistically Diverse Context of India.

Objectives: The growing prevalence of dementia, especially in low- and middle-income countries (LMICs), has raised the need for a unified cognitive screening tool that can aid its early detection. The linguistically and educationally diverse population in India contributes to challenges in diagnosis. The present study aimed to assess the validity and diagnostic accuracy of the Indian Council of Medical Research-Neurocognitive Toolbox (ICMR-NCTB), a comprehensive neuropsychological test battery adapted in five languages, for the diagnosis of dementia. Methods: A multidisciplinary group of experts developed the ICMR-NCTB based on reviewing the existing tools and incorporation of culturally appropriate modifications. The finalized tests of the major cognitive domains of attention, executive functions, memory, language, and visuospatial skills were then adapted and translated into five Indian languages: Hindi, Bengali, Telugu, Kannada, and Malayalam. Three hundred fifty-four participants were recruited, including 222 controls and 132 dementia patients. The sensitivity and specificity of the adapted tests were established for the diagnosis of dementia. Results: A significant difference in the mean (median) performance scores between healthy controls and patients with dementia was observed on all tests of ICMR-NCTB. The area under the curve for majority of the tests included in the ICMR-NCTB ranged from 0.73 to 1.00, and the sensitivity and specificity of the ICMR-NCTB tests ranged from 70 to 100% and 70.7 to 100%, respectively, to identify dementia across all five languages. Conclusions: The ICMR-NCTB is a valid instrument to diagnose dementia across five Indian languages, with good diagnostic accuracy. The toolbox was effective in overcoming the challenge of linguistic diversity. The study has wide implications to address the problem of a high disease burden and low diagnostic rate of dementia in LMICs like India.

Bilingualism and Its Implications for Neuropsychological Evaluation.

OBJECTIVE: In the background of a large population of bilinguals globally, the study aimed to develop standards of neuropsychological testing in the context of bilingualism. Because bilingualism is known to affect cognitive processes, bilinguals and monolinguals were compared on their performance on cognitive tests, to investigate the possibility of the need for separate normative data for the two groups. METHOD: A comprehensive neuropsychological test battery, standardized across five Indian languages: the Indian Council of Medical Research-Neuro Cognitive Tool Box (ICMR-NCTB) was administered to 530 participants (267 monolingual and 263 bilinguals matched for age and education). A systematic method of testing cognition in bilinguals was developed; to identify the appropriate language for testing, ensure language proficiency of examiner, and to interpret the bilingual responses. Additionally, the performance of bilinguals on the ICMR-NCTB was compared with monolinguals. RESULTS: Cognitive testing in the bilingual context was performed in the most proficient language of the participants, by examiners well versed with the language. Results from the language-based tests suggested that the frequent occurrence of borrowed- and language-mixed words required consideration while scoring. The reported bilingual effect on cognitive processes did not reflect as differences in the performance between bilinguals and monolinguals. CONCLUSIONS: Observations from the study provide robust recommendations for neuropsychological testing in the context of bilingualism. Results indicate that separate normative data may not be required for bilinguals and monolinguals. The study will be relevant and provide a reference framework to address similar issues in the large population of bilinguals in other societies.

A Screening Tool to Detect Stroke Aphasia: Adaptation of Frenchay Aphasia Screening Test (FAST) to the Indian Context.

BACKGROUND: Aphasia is a common consequence of stroke. To optimize recovery, it becomes critical as there are early identification and treatment of language deficits. The rising burden of stroke aphasia and lack of screening tools in the Indian context necessitates the need for a screening tool. OBJECTIVE: We aimed to adapt and validate the Frenchay Aphasia Screening Test (FAST) to the Indian context in two widely spoken Indian languages, Telugu and Kannada, for the literate and illiterate population. METHODS: A systematic process of adaptation and culturally appropriate modifications of the original FAST were done in 116 healthy controls and 115 patients. The validity of the adapted test was established. RESULTS: The optimum cut-off values for detecting aphasia in our sample ranged from 25 to 25.5 (literate) and 13.5 to 15.5 (illiterate) with high sensitivity and specificity. There was also a significant correlation between aphasia scores for adapted FAST and the Western Aphasia Battery (WAB), establishing good convergent validity. DISCUSSION: Results of the adaptation and validation of two Indian versions of FAST, suggest that it is an easy-to-use screening measure for detecting stroke-related language disabilities. The psychometric properties of the Indian version of FAST met the standardised requirements for adaptation and validation. CONCLUSIONS: The Indian version of FAST was found to be a reliable and valid bedside screening tool for aphasia in stroke patients. We aim that this study will facilitate the use of the test across other Indian languages and a large clinical population in the future.

Wada memory asymmetry scores and postoperative memory outcome in left temporal epilepsy.

BACKGROUND: Memory asymmetry scores are used in intracarotid amobarbital procedure (IAP) to predict memory outcome after anterior temporal lobectomy (ATL) in patients with temporal lobe epilepsy (TLE). Reversed asymmetry (RA) of memory scores occurs in a minority of patients, with better memory performance observed following contralateral injection. Left ATL patients with RA are reported to have poorer postoperative verbal memory outcome. Studies also suggest that dysphasia during language dominant left hemisphere injection may contribute to lower right-sided memory scores seen in RA. PURPOSE: To examine the role of dysphasia in RA and investigate the relationship between RA scores and memory outcome after ATL. METHOD: IAP asymmetry scores and duration of speech arrest following bilateral IAP injection were examined in 50 patients with unilateral left TLE. Postoperative memory outcome was examined in a subset of patients (n=31). RESULTS: Thirty-nine percent of patients had RA on IAP. The duration of speech arrest after left injection was significantly longer in the RA group compared to the expected asymmetry (EA) group. RA was not associated with negative postoperative memory outcome. CONCLUSIONS: In left TLE patients, RA of IAP memory scores does not preclude good postoperative memory outcome. Prolonged speech arrest after left injection may lower right side memory scores contributing to misleading RA. Memory asymmetry patterns are sensitive to IAP protocol effects; therefore, RA may not be a robust predictor of memory outcome following left ATL.

Marriage in people with epilepsy: A compelling theme for psycho-behavioral research.

People with epilepsy frequently experience problems in marriage including reduced marital prospects, poor marital outcomes and diminished quality of married life. Conversely, marriage might impact epilepsy self-management and quality of life in people with epilepsy. There is little in published literature on marriage and epilepsy, so there is a need for psycho-behavioral research. Here, we focus on arranged marriages which, although now rare in western cultures, are widely prevalent in South Asian communities. Arranged marriages, in which families rather than individuals choose marital partners, are particularly problematic because epilepsy is frequently hidden during marital negotiations as well as later. From the psycho-behavioral perspective, marital prospects, outcomes and satisfaction should be examined in relation to the type of marriage (arranged vs. love) and whether or not epilepsy is hidden. Additionally, culturally-relevant tools to appraise marital quality and epilepsy self-management within marriage should be developed. The main objective should be to develop a multi-sectorial action plan with interventions at several different levels involving different stakeholders to mitigate stigma associated with epilepsy in matrimony.

Is psychiatric assessment essential for better epilepsy surgery outcomes?

Epilepsy surgery is one of the most accepted and beneficial treatment for resistant epilepsies. However there is some variability in the comprehensive epilepsy care programs offered globally. Many centers do not do a psychiatric assessment unless required. It is now evident from a large body of research that epilepsy is associated with psychiatric morbidity which is also seen in patients considered for epilepsy surgery. There is also evidence to state that the risk for worsening or de novo psychiatric disorders is often seen post surgery. This calls for a comprehensive psychiatric assessment of all patients enrolled for the epilepsy surgery program to be evaluated pre and post surgically to minimize the risk of post surgical psychological disturbances and/or poor quality of life. Efficacious treatment of psychiatric disorders in those having psychiatric morbidity contributes to improved patient wellbeing, seizure freedom and better quality of life. Hence there is a need for most centers globally to include regular psychiatric assessment of epilepsy surgery patients as a protocol.
