School victimization and psychosocial adjustment among Eastern European adopted adolescents across Europe.

BACKGROUND: Little is known about bullying experienced by internationally adopted teens residing in Europe. OBJECTIVES: Within the framework of an international research effort involving several European countries, the main goal of this study was to explore the experiences of bullying victimization suffered by adopted adolescents, as well as its impact on their psychological adjustment. METHODS: The sample consisted of 199 adolescents born in Eastern European countries and adopted in France (n = 50), Italy (n = 59), Norway (n = 25) and Spain (n = 65). RESULTS: More than half of the adopted adolescents had been exposed to some form of peer victimization in the previous 2 months, with verbal harassment and social exclusion being the most common forms of victimization. Differences between receiving countries were not statistically significant, suggesting a common pattern for Eastern European adopted adolescents living in Western Europe. More frequent experiences of peer victimization were associated with more psychological difficulties among the adopted adolescents. CONCLUSIONS: Findings highlight that adopted adolescents might have considerable difficulties in social integration with peers; these experiences of peer victimization might play an important role hindering their psychosocial adjustment. The socioemotional development of adopted people is not only linked to their pre-adoptive experiences; factors in their daily lives (i.e., peer relationships) may also be associated with their psychological adjustment later in life. Interventions are needed to promote the real inclusion of these groups of children in their social and educational contexts.

A multi-sectoral community development intervention has a positive impact on diet quality and growth in school-age children in rural Nepal.

Poor diet quality (diet diversity and animal-source food [ASF] consumption) during childhood negatively affects growth, development, behaviour and physiologic function in later life. Relatively less is known about the impact of poor diet on the growth of school-age children compared to children <5 years of age, especially in low/middle-income countries. A better understanding of delivery strategies for effective interventions to improve diet and hence growth in school-age children is needed. A 36-month longitudinal controlled impact evaluation in rural Nepal assessed the nutrition and growth of children <5 years of age in families assigned via community clusters to full package intervention (community development, training in nutrition [during pregnancy and for children <5 years] and livestock husbandry), partial package (training only) or control (no inputs). Concurrent data were collected prospectively (baseline plus additional four rounds) on school-age children (5-8 years at baseline) in these households; the present study analysed findings in the cohort of school-age children seen at all five study visits (n = 341). Diet quality improved more in the full package school-age children compared to those in partial package or control households. full package children consumed more ASF (ß +0.40 [CI 0.07,0.73], p < 0.05), more diverse diets (ß +0.93 [CI 0.55,1.31], p < 0.001) and had better head circumference z-scores (ß +0.21 [CI 0.07,0.35], p < 0.01) than control children. In conclusion, a multi-sectoral community development intervention was associated with improvements in diet and growth of school-age children in rural Nepal even though the intervention focused on the diet of children <5 years of age. The diet and growth of school-age children can be favourably influenced by community-level interventions, even indirectly.

Trajectories of child growth, child development, and home child-rearing quality during the Covid pandemic in rural Nepal.

BACKGROUND: Children, especially disadvantaged children in poor countries, were expected to be among the "biggest victims" of the Covid pandemic. Economic burdens, decreased nutritious foods, reduced medical care, school closures, and ill-health or death of family members were predicted to increase child undernutrition and developmental delays, and diminish home child-rearing quality. METHODS: A planned nutrition intervention could not be implemented due to Covid restrictions. However, three surveys (pre-Covid [December 2019], July 2021, and September 2021) in 280 Nepali households (309 parent-dyads, 368 children, 6-66 months old) collected demographics, child anthropometry and development (Ages and Stages Questionnaire-3 [ASQ-3]), and home child-rearing quality (caregiver engagement, learning resources, adult supervision [UNICEF's Multiple Indicator Cluster Survey]). Mixed-effect regression models adjusted for household (wealth, maternal education) and child factors (age, gender) and survey round. RESULTS: Height, mid-upper-arm circumference, and head circumference measurements improved over time. The total ASQ-3 score did not change: Communication scores increased while fine motor and personal-social scores declined. Girls' growth and development worsened more than boys. Caregiver engagement (especially mothers') generally declined, but learning resource availability increased. More children were left unsupervised at Round 2 than Round 1 or 3. CONCLUSIONS: In this sample, some aspects of child growth, development, and home child-rearing quality improved while others declined. Better understanding of these changes in child well-being and the family environment during the pandemic could provide insight on how to protect children during future crises.

Subjective Cognitive Dysfunction in Patients with Dizziness and Vertigo.

INTRODUCTION: Patients with vestibular disorders sometimes report cognitive difficulties, but there is no consensus about the type or degree of cognitive complaint. We therefore investigated subjective cognitive dysfunction in a well-defined sample of neuro-otology patients and used demographic factors and scores from a measure of depression, anxiety, and stress to control for potential confounding factors. METHODS: We asked 126 neuro-otology clinic outpatients whether they experienced difficulties with thinking, memory, or concentration as a result of dizziness or vertigo. They and 42 nonvertiginous control subjects also completed the Neuropsychological Vertigo Inventory (NVI, which measures cognitive, emotional, vision, and motor complaints), the Everyday Memory Questionnaire (EMQ), and Depression, Anxiety, and Stress Scales (DASS). RESULTS: In the initial interview questions, 60% of patients reported experiencing cognitive difficulties. Cognitive questionnaire scores were positively correlated with the overall DASS score and to a lesser extent with age and gender. Therefore, we compared patients and controls on the NVI and EMQ, using these mood and demographic variables as covariates. Linear regression analyses revealed that patients scored significantly worse on the total NVI, NVI cognitive composite, and 3 individual NVI cognition subscales (Attention, Space Perception, and Time Perception), but not the EMQ. Patients also scored significantly worse on the NVI Emotion and Motor subscales. CONCLUSIONS: Patients with dizziness and vertigo reported high levels of cognitive dysfunction, affecting attention, perceptions of space and time. Although perceptions of cognitive dysfunction were correlated with emotional distress, they were significantly elevated in patients over and above the impact of depression, anxiety, or stress.

How frequently is anxiety and depression identified and treated in hospital and community samples of adults with epilepsy?

While it is often stated that psychiatric co-morbidity in PWE is under-recognized and under-treated, little research has directly examined this assertion. The aims of this study were to understand the rates of confirmed diagnosis and treatment of depression and anxiety in people with epilepsy (PWE). Two samples were recruited: a hospital sample of 106 adult outpatients with epilepsy who underwent a structured psychiatric diagnostic interview and a community sample of 273 PWE who completed validated measures of depression and anxiety symptoms online. In the hospital sample, fewer participants who met criteria for an anxiety disorder had received a prior diagnosis compared to those with a depressive disorder (36% vs 67%). In the community sample, the rates of known diagnosis were comparable (65% vs. 69%). Approximately, one-third of PWE with an anxiety disorder (or clinically significant symptoms) were receiving current treatment compared to approximately half of those with depression. These findings confirm the high rates of psychiatric co-morbidity in PWE and indicate that a large proportion of anxiety diagnoses, in particular, are undetected and not receiving either pharmacological or psychological support. Future work is needed to improve the detection and management of psychiatric co-morbidity in PWE, especially for anxiety disorders.

Infections and nutritional status of internationally adopted children in France.

AIM: In the context of global changes in the epidemiology of internationally adopted children (IACs), the prevalence of infectious diseases and nutritional impairment has not been recently reviewed. Moreover, in France, these characteristics of the children according to their continents of origin and preadoption special needs (SN) status have been incompletely explored. METHODS: Demographic, infectious data and anthropometric of all the newly arrived IACs seen in a specialised clinic for international adoptees in Paris, France, between 2013 and 2016 were retrospectively reviewed. RESULTS: Three hundred and fifty IACs [mean age: 3.4 years (±2.7), 204 male] from 39 countries were included; 55% had SN. Ninety-nine patients had at least one infection, 42% being classified as 'serious' (chronic viral infection, tuberculosis or malaria). Chronic viral infection was diagnosed in 26 (7%) patients (HIV: 16 cases, HBV: 5, HCV: 4) and affected especially Asian children (P < .001). The prevalence of stunting, underweight, wasting and microcephaly was, respectively, 25%, 22%, 15% and 8%. Stunting was more frequent in children from Eastern Europe (P = .02), while SN children were more often microcephalic or underweight (respectively P = .03 and .02). CONCLUSION: The prevalence of serious infections and nutritional impairment remains high in IACs and requires early detection and careful follow-up.

Maternal depression is associated with less dietary diversity among rural Nepali children.

Maternal depression has been associated with adverse child growth and development; less is known about its relation to children's diet. In a cross-sectional study embedded at endline of a longitudinal community development intervention, mothers of 629 children (age 23-66 months) in rural Nepal responded to household and children's diet questionnaires and were screened for depression. Child anthropometry and development (Ages and Stages Questionnaire) were assessed. Regression models examined children's diet, growth and development, adjusting for household, child and maternal characteristics. The prevalence of maternal depression was 21%. Maternal depression was associated with 11% lower likelihood that the child consumed one additional food group [Poisson regression, adjusted relative risk (aRR) 0.89, 95% confidence intervals (95% CI 0.81, 0.99), p = 0.024] and 13% lower likelihood that the child consumed one additional animal source food (ASF) [aRR 0.87, (95% CI 0.76, 1.01), p = 0.061] compared with children of nondepressed mothers. However, maternal depression was not associated with either child anthropometry or development: these outcomes were strongly associated with better home child-rearing quality. Stunting also related to child age and intervention group; child development related to mother's education and household wealth. This study suggests a correlation between maternal depression and child dietary diversity. This association could be due to unmeasured confounders, and therefore, further research is warranted. Understanding the relationship of depression to child outcomes-and the role of other potentially compensatory household factors-could help address some of the earliest, modifiable influences in a child's life and contribute to innovative approaches to improve child well-being.

The impact of hippocampal damage on appetitive control.

Animal data indicates the hippocampus assists appetite-regulation.  We tested this in humans, contrasting two patients (DW, JC) with hippocampal damage to controls on an appetite-regulation test conducted hungry and sated.  When hungry, controlsviewed palatable snacks and reported a desire to eat them, a memory-based judgment.  After sampling them, they reported liking their taste.  Post-lunch (DW ate little, precluding a test of our hypothesis), controls showed a large decrease in desire for the snacks, but less change in taste-liking.  JC ate like controls, but reported no change in desire across states, suggesting that the human hippocampus also contributes to appetite-regulation.

Group-based cognitive behavioral therapy program for improving poor sleep quality and quality of life in people with epilepsy: A pilot study.

Sleep difficulties are commonly reported by patients with epilepsy and can have a detrimental impact on overall quality of life. The purpose of this pilot study was to assess the efficacy of a psychotherapeutic approach, namely Cognitive Behavioral Therapy for Insomnia (CBT-I), in improving sleep quality in patients with epilepsy. Twenty outpatients with epilepsy who reported poor sleep quality were randomized to either a control or CBT-I treatment group, which involved four group-based CBT-I sessions, delivered on a weekly basis. In addition to completing a range of standardized measures related to sleep quality and quality of life, participants also monitored their sleep with a self-completed sleep diary over a two-week period, on two separate occasions. Following CBT-I treatment, no between-group difference was found on any sleep or quality of life measure. However, both the treatment and control groups improved on measures of sleep quality, quality of life, sleep hygiene behaviors, and dysfunctional beliefs about sleep. These findings suggest that sleep monitoring alone may have the potential for prompting healthy behavior change in this clinical population.

Multisectoral community development in Nepal has greater effects on child growth and diet than nutrition education alone.

OBJECTIVE: To compare the impact on child diet and growth of a multisectoral community intervention v. nutrition education and livestock management training alone. DESIGN: Longitudinal community-based randomized trial involving three groups of villages assigned to receive: (i) Full Package community development activities, delivered via women's groups; (ii) livestock training and nutrition education alone (Partial Package); or (iii) no intervention (Control). Household surveys, child growth monitoring, child and household diet quality measures (diet diversity (DD), animal-source food (ASF) consumption) were collected at five visits over 36 months. Mixed-effect linear regression and Poisson models used survey round, treatment group and group-by-round interaction to predict outcomes of interest, adjusted for household- and child-specific characteristics. SETTING: Banke, Nepal. PARTICIPANTS: Households (n 974) with children aged 1-60 months (n 1333). RESULTS: Children in Full Package households had better endline anthropometry (weight-for-age, weight-for-height, mid-upper-arm-circumference Z-scores), DD, and more consumption of ASF, after adjusting for household- and child-specific characteristics. By endline, compared with Partial Package or Control groups, Full Package households demonstrated preferential child feeding practices and had significantly more improvement in household wealth and hygiene habits. CONCLUSIONS: In this longitudinal study, a comprehensive multisectoral intervention was more successful in improving key growth indicators as well as diet quality in young children. Provision of training in livestock management and nutrition education alone had limited effect on these outcomes. Although more time-consuming and costly to administer, incorporating nutrition training with community social capital development was associated with better child growth and nutrition outcomes than isolated training programmes alone.

MILK Symposium review: Milk consumption is associated with better height and weight in rural Nepali children over 60 months of age and better head circumference in children 24 to 60 months of age.

Child undernutrition afflicts >150 million children worldwide, contributing to poor child growth, increased risk of infections, and loss of developmental potential. Animal-source foods (ASF) can ameliorate these problems by providing high-quality, high-density, and bioavailable protein and micronutrients. However, many children in developing countries lack ASF in their diet, although generally milk is the ASF most often consumed. Nevertheless, the relation of ASF-and that of specific ASF-to child growth in these contexts has been difficult to define, as has the association between diet and child and household factors in influencing growth outcomes. To better understand these relationships, we evaluated child growth by age groups (6-23 mo, 24-60 mo, and >60 mo) in relation to ASF consumption in rural Nepal. We used an observational study design that leveraged a data set generated through a 3-yr longitudinal controlled impact evaluation of a community-development intervention. Child anthropometry and 24-h diet recall were obtained at 5 household visits. At baseline, children were generally undernourished: 47% were stunted, 46% underweight, 17% wasted, and 24% microcephalic. Patterns of undernutrition varied with age but improved somewhat over time. Over the 3-yr period of study (9,283 observations), ASF were consumed infrequently: milk in 28% of assessments, meat in 27%, and eggs in 15%. Consumption patterns differed by age group, with younger children (6-23 mo) consuming more milk and less meat than children 24 to 60 or >60 mo. Consumption of even a single ASF at any of the 5 surveys was associated with greater growth in bivariate analysis. After adjustment for household (group assignment, survey round and its interaction, wealth, income, livestock and land ownership, maternal education) and child factors (age, sex, baseline anthropometry), mixed-effect linear regression analysis showed that milk consumption related to higher height for age and weight for age z-scores for children >60 mo of age and to higher head circumference z-score for children age 24 to 60 mo. For children >60 mo, egg consumption also related to higher weight z-scores. Household and child factors also influenced these outcomes. Of the ASF, milk had the strongest and most consistent relationship to child growth. Better measures of diet intake could reveal stronger associations between diet consumption patterns and child growth. Regardless, milk may be a key ASF to target for growth promotion among undernourished rural Nepali children.

Diet quality over time is associated with better development in rural Nepali children.

Developmental delays affect between 150 and 200 million children <5 years of age worldwide. Outside of diet supplement studies, relatively little is known about the relationships between diet quality and developmental status in resource-poor settings. We examined associations between different aspects of dietary quality (dietary diversity score [DDS] and animal-source food [ASF] consumption) and child development (assessed using the Ages and Stages Questionnaire-3 [ASQ-3]) among children whose families were enrolled in a community development intervention trial (implemented by Heifer Nepal) in western Nepal. Two sets of analyses were performed: (a) cross-sectional Sample (N = 629) seen at the endline survey and (b) longitudinal sample (N = 269) with complete dietary records (six surveys over 48 months). In both samples, child development was significantly related to household wealth, maternal education, and especially home environmental quality. In the cross-sectional sample, greater consumption of eggs (adjusted odds ratio [aOR] 0.80, p = .04) or dairy products (aOR 0.95, p = .05) over the previous 7 days significantly reduced odds of low total ASQ score, by logistic regression analysis. In the longitudinal sample, only egg consumption and cumulative DDS and ASF scores were associated with significantly reduced odds of low total ASQ score (aORs 0.59-0.89). In adjusted linear regression analysis, both cumulative DDS (ß [CI]: 1.92 [0.4, 3.5]) and ASF scores (2.46 [0.3, 4.7]) were significantly associated with greater continuous total child development. Programmes targeting child development must address home environmental quality as well as long-term diet quality.

Design and validation of two measures to detect anxiety disorders in epilepsy: The Epilepsy Anxiety Survey Instrument and its brief counterpart.

OBJECTIVE: The study objective was to develop and validate the first epilepsy-specific anxiety survey instrument (Epilepsy Anxiety Survey Instrument [EASI]) alongside a briefer screening instrument to detect anxiety disorders in routine clinical practice (brEASI). METHODS: The instruments were developed utilizing a mixed-methods approach in four related studies. Pilot items were developed following qualitative interviews with people with epilepsy (PWE; Study 1) and consultation with multidisciplinary experts in anxiety and epilepsy (Study 2). PWE (n = 314) then completed pilot items alongside existing measures of anxiety and depression (Study 3). Factor analysis was conducted to refine the scale and select well-performing items for a briefer diagnostic screener (brEASI). The brEASI was validated against a gold standard diagnostic interview in 106 PWE recruited from an outpatient epilepsy service (Study 4). Receiver operating characteristic analysis was conducted to determine the brEASI's diagnostic performance. RESULTS: Twenty-six pilot items were generated based on the findings of Studies 1 and 2. Analyses in Study 3 resulted in an 18-item EASI, and eight well-performing items were selected for the brEASI. The area under the curve (AUC) of brEASI was excellent (AUC = 0.89, 95% confidence interval = 0.82-0.94). At a cutoff of 7, it demonstrated a sensitivity of 76% and specificity of 84% for identifying Diagnostic and Statistical Manual of Mental Disorders, 5th edition anxiety disorders. SIGNIFICANCE: The EASI and brEASI represent the first valid and reliable epilepsy-specific anxiety instruments. The EASI has been designed to comprehensively assess anxiety in PWE, whereas the brEASI may be used within busy neurology settings to provide rapid information to aid diagnoses of anxiety disorders. Given the significant prevalence and burden of anxiety in PWE, these tools are important potential solutions to improve the understanding and detection of anxiety in epilepsy.

The impact of sleep characteristics and epilepsy variables on memory performance in patients with focal seizures.

Disturbed sleep can negatively affect overnight memory retention as well as new learning the subsequent day. In healthy participants, positive associations between memory performance and sleep characteristics (e.g., time spent in slow-wave sleep [SWS]) have been detected. In a previous study, we found that SWS was much reduced in patients with focal seizures, but when correlations between memory complaints and various sleep characteristics were considered, the only significant relationship was with the time to onset of rapid eye movement (REM) sleep (i.e., REM latency). In this study, we investigated the relationships between sleep, epilepsy, and objective memory performance variables. Twenty-five patients with focal seizures had their memory tested while undergoing a two-day ambulatory electroencephalography (EEG). The sleep variables of interest were the percentage of time spent in SWS (%SWS) and REM latency. Epilepsy variables included the presence of (1) seizures, (2) interictal epileptiform discharges, and/or (3) hippocampal lesions as well as site of seizure origin (temporal vs extratemporal). Overnight retention (of autobiographical events, a story, and a complex geometric figure) and the ability to learn a word list on day 2 were the measures of memory. A significant positive correlation was found between word-list learning and %SWS during the previous night. A significant negative correlation was observed between REM latency and overnight retention of autobiographical events. Overnight retention scores for the story and geometric figure were not related to sleep characteristics but were negatively affected by the presence of epileptiform activity. Story retention was also worse for temporal lobe epilepsy (TLE) than for patients with extratemporal epilepsy (ETE). Those with hippocampal lesions were more impaired than those without lesions on word-list learning, autobiographical events' retention, and story retention. When multiple contributing factors were entered into regression analyses, %SWS was found to be the best predictor of subsequent word-list learning, whereas the presence of a hippocampal lesion was the best predictor of overnight retention of autobiographical events and a story. These findings provide further evidence of the ways in which particular sleep characteristics are associated with memory and suggest that treatment of sleep disturbances in patients with epilepsy might be helpful for improving their performance.

A qualitative examination and theoretical model of anxiety in adults with epilepsy.

OBJECTIVE: There is an elevated prevalence of anxiety disorders among people with epilepsy, and the comorbidity of anxiety in epilepsy is associated with adverse medical and psychosocial outcomes. Despite its importance, little is known about what psychosocial or epilepsy factors may be associated with the development of anxiety. The aim of this qualitative study was to determine what factors may explain why some people with epilepsy develop anxiety disorders and others do not. METHODS: Adults with epilepsy were recruited from an outpatient epilepsy service. Semistructured interviews were conducted with 26 participants, 15 of whom reported clinically significant levels of anxiety. Grounded theory analysis was used to develop a theoretical model of anxiety development in the context of epilepsy. RESULTS: Qualitative analyses revealed a number of processes that appeared to account for the development of anxiety in the context of epilepsy. These included inflated estimates regarding epilepsy-specific risks and excessive attempts to avoid these risks. Such excessive avoidance often resulted in greater interference with participants' role functioning, thus risking ongoing quality of life. A number of premorbid and contextual factors also appear to be implicated in the development of anxiety. CONCLUSION: This investigation provides a comprehensive account for the development of anxiety in epilepsy, which is consistent with existing theories of anxiety development and maintenance. Importantly, this model provides a foundation for future research and appropriate treatment strategies to address anxiety in people with epilepsy.

Women's education level amplifies the effects of a livelihoods-based intervention on household wealth, child diet, and child growth in rural Nepal.

BACKGROUND: Many organizations seek to alleviate poverty in the developing world, often focusing their interventions on women. The role, status, and education of women are fundamentally important facets of development. Thus, understanding the interaction of women's educational level and the response to interventions is important. Therefore, we examined the impact of educational level of household adults on responses to a livestock-based community intervention. METHODS: Six pair-matched communities in 3 districts of Nepal (Chitwan/Nawalparasi/Nuwakot), were randomly assigned to receive community development activities via women's self-help groups at baseline or 1 year later. At 6 intervals over 48 months, a 125- item questionnaire addressing family demographics and child health/nutrition was completed in each household, plus child growth monitoring. Results were analyzed in relation to the highest education attained by any woman in the household, the child's mother, men, or any other adult in the household. RESULTS: Outcomes (wealth, water/toilet availability, child diet diversity and growth) all significantly related to adult education. However, notable differences were found comparing the impact of men's and women's education. Percent change in wealth score was significant only in households where women had primary or secondary education (respectively, p = .0009 and p < .0001). Increased soap use related only to women's education (p < .0001). When adjusted for group assignment, baseline income, wealth, and animal scores, higher women's education was significantly associated with increased household wealth (p < .0001), better child height-for-age z scores (HAZ, p = .005), and improved child diet diversity (p = .01). Higher mother's education predicted better child HAZ (primary, p = .01, secondary, p = .03) and diet diversity (primary, p = .05, secondary, p < .0001). Higher men's education was significantly associated with household wealth (p = .02) and child diet diversity (p = .04), but not HAZ; higher education of any household member was associated only with household wealth (p < .0001). Moreover, households where the mother's education was better than the best-educated man also were significantly more likely to have children with better HAZ and dietary diversity (p = .03, p < .0001). Thus, the educational level of women and mothers had the broadest impact on child outcome variables. CONCLUSIONS: Household characteristics vary among participants in most community development projects. Of these, adult education likely mediates response to the inputs provided by the intervention. Particularly in interventions directed towards women, better education may enhance the ability of households to put interventions into practice, thus improving wealth, hygiene, and child diet and growth indices.

Accelerated Long Term Forgetting in patients with focal seizures: Incidence rate and contributing factors.

BACKGROUND: Accelerated Long Term Forgetting (ALF) is usually defined as a memory impairment that is seen only at long delays (e.g., after days or weeks) and not at shorter delays (e.g., 30min) typically used in clinical settings. Research indicates that ALF occurs in some patients with epilepsy, but the incidence rates and underlying causes have not been established. In this study, we considered these issues. METHODS: Forty-four patients with a history of focal seizures were tested at 30min and 7day delays for material from the Rey Auditory Verbal Learning Test (RAVLT) and Aggie Figures Test. Recently published norms from a matched group of 60 control subjects (Miller et al., 2015 ) were used to determine whether patients demonstrated ALF, impairment at 30min or intact memory performance. RESULTS: The incidence of ALF in the epilepsy patients (18%) was >3 times higher than normal on the RAVLT, but no different (7%) from the incidence in normal subjects on the Aggie Figures. A different, but again significantly high, proportion of patients (36%) showed shorter-term memory deficits on at least one task. ALF was found mainly in patients with temporal-lobe epilepsy, but also occurred in one patient with an extratemporal seizure focus. Presence of a hippocampal lesion was the main predicting factor of ALF. CONCLUSIONS: Many patients with a focal seizure disorder show memory deficits after longer delays that are not evident on standard assessment. The present study explored the factors associated with this ALF memory profile. These new findings will enhance clinical practice, particularly the management of patients with memory complaints.

Imagining future events in patients with unilateral temporal lobe epilepsy.

OBJECTIVES: Imagining future events, which contain episodic and non-episodic details, has been found to (1) engage the temporal lobes bilaterally and (2) be impaired in patients with bilateral temporal lobe pathology. Here, we examined whether unilateral temporal lobe dysfunction also impairs the ability to generate future events. DESIGN: Prospective cross-sectional. METHODS: Twenty patients with a history of unilateral temporal lobe epilepsy [TLE; 10 left (LTLE) and 10 right (RTLE)] and 20 normal control (NC) subjects comparable on age, sex and education completed the Adapted Autobiographical Interview, which required recall of past and generation of future events and distinguished episodic (internal) from non-episodic (external) details. Participants also completed a battery of neuropsychological tests. RESULTS: Patients with unilateral TLE were significantly impaired in provision of internal details for past and future events, but not in the generation of external details. Examination of detail subcategories revealed that patients with LTLE did exhibit a significant deficit relative to patients with RTLE (and NC) with respect to the generation of perceptual details for both past and future events. Moreover, patients with LTLE generated significantly fewer place details for future events (relative to NC only). The overall number of internal details recalled by patients with LTLE was related to semantic fluency. CONCLUSIONS: Our study provides the first evidence that unilateral temporal lobe dysfunction is associated with not only impaired recall of past, but also the generation of future episodic details. Clinically, deficits in future thinking may reduce motivation and decision-making, and as such adversely impact behavioural regulation and socialization. PRACTITIONER POINTS: Patients with temporal lobe epilepsy generate less details when asked to describe past and potential future events, particularly with regard to details involving specific events, places and perceptions. These same patients are aware of their difficulties in this realm, but judge their past memories as similar in vividness and even more personally significant than the memories generated by control participants. The deficits in generation of future episodic details were particularly pronounced in patients with left temporal lobe epilepsy. Verbal semantic fluency was correlated with the ability to generate future scenarios.

Perception of odor-induced tastes following insular cortex lesion.

Lesions of the insula can affect olfaction and gustation. Here, we examined the effect of insula lesions on taste and taste-like experiences generated via smelling (i.e., odor-induced tastes) in patients with focal insula lesions and intact olfaction. From a set of 16 patients with lesions to the insula, we found 7 (6 with right-sided lesions) who performed normally on various olfactory measures. These were compared to 42 normal control subjects on tests of gustatory and odor-induced taste perception as well as control measures. The patients were impaired relative to controls on most gustatory measures. They were also impaired on tests of odor-induced taste perception, primarily for stimuli presented on the left side. Examining cases individually revealed evidence of a dissociation: two patients exhibited no impairment in odor-induced taste perception in spite of gustatory deficits. Together, these findings suggest that the insula mediates taste recognition, hedonics, and intensity judgments as well as odor-induced taste perception. However, the areas responsible for aspects of taste perception and those responsible for odor-induced taste do not fully overlap each other and they are also independent of olfactory areas.
