Loss of control as a transdiagnostic feature in obesity-related eating behaviours: A systematic review.

OBJECTIVE: Emerging evidence suggests that loss of control (LOC) may present as a common feature across disordered eating behaviours. However, there has been limited research on the transdiagnostic nature of LOC in this area. The primary aim of this study was to systematically review disordered eating behaviours and measures of LOC in clinical and non-clinical populations. METHOD: Electronic searches of the relevant databases were conducted. Selected articles were screened for eligibility and assessed for methodological quality. RESULTS: Thirty-four studies met inclusion criteria. Findings demonstrated that LOC was associated with disordered eating behaviours across bariatric populations, eating disorder populations, and community populations. Specifically, LOC was associated with binge eating (subjective and objective episodes), grazing, night eating, and emotional or stress eating. Findings also revealed that LOC was inconsistently operationalised across studies, with varied approaches to measuring the construct. CONCLUSION: Overall, the findings from this review provide support for LOC as a transdiagnostic feature of disordered eating behaviours. Future studies should utilise robust multi-method assessments to measure the severity of LOC, which may provide greater insight into how LOC manifests across different eating disorder presentations.

Accelerated long-term forgetting in children with temporal lobe epilepsy: A timescale investigation of material specificity and executive skills.

Recently, children with temporal lobe epilepsy (TLE) were found to be at risk of accelerated long-term forgetting (ALF). In this study, we examined the temporal trajectory of ALF, while exploring the relationship between ALF, executive skills, and epilepsy variables. Fifty-one children, (23 with TLE and 28 typically developing) completed a battery of neuropsychological tests of verbal and visual memory, executive skills, and two experimental memory tasks (verbal and visual) involving recall after short (30-min) and extended (1-day and 2-week) delays. Side of seizure focus and hippocampal integrity were considered. On the visual task (Scene Memory), children with TLE performed comparably to typically developing children following a 30-min and 1-day delay, although worse than typically developing children at 2 weeks: ALF was observed in children with right TLE focus. The two groups did not differ on the experimental verbal memory task. Children with TLE also had worse performance than typically developing children on standardized verbal memory test and on tests of executive skills (i.e., verbal generativity, inhibition, working memory, complex attention). Only complex attention was associated with visual ALF. ALF was present for visuo-spatial materials in children with TLE at two weeks, and children with right TLE were most susceptible. A relationship was identified between complex attention and long-term forgetting. The findings extend our understanding of difficulties in long-term memory formation experienced by children with TLE.

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.

Accelerated long-term forgetting in children with genetic generalized epilepsy: The temporal trajectory and contribution of executive skills.

PURPOSE: Long-term memory, which is critical for social and vocational functioning, is impaired in children with genetic generalized epilepsy (GGE). In this study, we examined the relationship between the temporal pattern of long-term forgetting for visual and verbal materials and executive skills in children with GGE. METHOD: Thirty-two children, 17 with GGE and 25 typically developing age-matched controls completed standardized tests of short-term memory (recall after a 30-minute delay), executive skills, and experimental long-term memory tasks (one verbal and one visual) involving recall after one short (30-minute), and two long (1-day, 2-week) delays. RESULTS: On the long-term visual memory task, children with GGE performed comparably with typically developing children at a 30-minute delay (p = .298), although obtained lower object placement accuracy score, at 1 day (p = .039) and at 2 weeks (p = .022) relative to typically developing children. On the verbal task, the between-group difference was not significant at any delay. In children with GGE, poorer object placement accuracy at two weeks correlated with lower visuospatial short-term memory (r = -0.624, p = .005) and verbal working memory (r = -0.448, p = .041). CONCLUSIONS: This study provided several novel findings. For the first time, accelerated long-term forgetting (ALF) was found in long-term visual memory in children with GGE, despite comparable learning and recall at 30 min. Study results indicated that deficits in long-term visual memory are present after one day, increase over time, and may relate to reduced executive skills. Our findings can be used to inform our understanding of the temporal trajectory of ALF and contribution of executive skills.

Memory Rehabilitation in Patients with Epilepsy: a Systematic Review.

Memory failure is a common clinical concern of patients with epilepsy and is associated with significant functional impairments. Thus, memory rehabilitation is of critical clinical importance. In this article, we aimed to systematically evaluate the efficacy of memory rehabilitation in patients with epilepsy. The Preferred Items for Systematic Reviews and Meta-Analyses (PRISMA) was used to guide searches, extraction and reporting of data in this review. PsycINFO, Medline and PsychBITE searches yielded 95 studies. Twelve papers met inclusion criteria, reporting outcomes of cognitive or behavioural interventions that specifically targeted the rehabilitation of memory in patients with epilepsy. Methodological rigour was rated using the Single-Case Experimental Design (SCED) scale for single-case studies and a modified version of the Downs and Black checklist for group studies. Twelve prospective studies, nine group (six pre-post design, one waitlist crossover, two randomised controlled trials) and three single-case studies were identified. Eleven of the studies included adults, eight of which involved adults with temporal lobe epilepsy (TLE). One paediatric study was identified. The quality of group studies ranged from 36% (poor) to 72% (good), using the modified Downs and Black checklist. Single-case studies were assessed using the SCED scale and assessed to range in quality from four to seven out to 11. Overall, memory rehabilitation was associated with improved memory function in all studies. Verbal memory outcomes were most commonly examined and associated with improvements. This review found that the level of evidence available to support rehabilitation of memory in patients with epilepsy was generally weak and inconsistent. Nevertheless, studies conducted to date, albeit of limited methodological quality, offer preliminary evidence that memory rehabilitation is associated with improvements in verbal memory in patients with temporal lobe epilepsy. Little is known about the efficacy of memory rehabilitation in patients with non-TLE, children, and other aspects of memory difficulties. Guidelines for future research are proposed.

Attention deficits in children with epilepsy: Preliminary findings.

OBJECTIVE: Attention difficulties are a common clinical complaint among children with epilepsy. We aimed to compare a range of attentional abilities between groups of children with two common epilepsy syndromes, Temporal Lobe Epilepsy (TLE) and Idiopathic Generalized Epilepsy (IGE), and to healthy controls. We also investigated whether epilepsy factors (laterality of seizure focus, epilepsy onset, duration, and severity) were related to attentional abilities. METHODS: Multiple dimensions of attention (selective, sustained, and divided attention and attentional control) were assessed directly with standardized neuropsychological measures in 101 children aged 6-16years (23 children with TLE, 20 with IGE and 58 healthy controls). Attention was also assessed indirectly, via a parent-report measure. RESULTS: Children with TLE performed worse than children with IGE (p=0.013) and healthy controls (p<0.001) on a test of attentional control, but no between-group differences were apparent on tests of other attentional abilities. Compared to healthy controls, greater attention problems were reported by parents of children with TLE (p=0.006) and IGE (p=0.012). Left-hemisphere seizure focus and greater epilepsy severity were associated with poorer attentional control and sustained-divided attention, respectively, but no other epilepsy factors were associated with attentional abilities. SIGNIFICANCE: These findings suggest that children with localization-related epilepsy, but not generalized epilepsy, may be at risk of deficits in attentional control. Interventions aimed at improving attentional control may be targeted at children with localization-related epilepsy, particularly those with a left-hemisphere seizure focus, who appear to be particularly susceptible to this type of attentional deficit.

The protective role of resilience in the reporting of post-concussive symptoms within a non-clinical sample.

Objective: Despite being common following a brain injury, post-concussive symptoms (PCS) are highly prevalent in healthy and non-concussed individuals. Psychosocial factors likely subserve the maintenance of symptoms, and numerous studies have identified prominent risk factors associated with post-concussive symptom reporting (e.g. history of depression). However, few studies have investigated protective factors in this context. The aim of the current study was to examine the relationship between resilience and PCS, and to identify the factors subserving resilience within this relationship. Method: Healthy and non-concussed participants (n = 283, Mage = 22.70 years) completed questionnaires examining PCS (Rivermead Post-Concussion Symptom Questionnaire) and resilience (Resilience Scale for Adults), together with a screener of background demographic/clinical factors. Results: Resilience negatively predicted PCS above and beyond the effect of demographic and clinical factors previously implicated in the reporting of PCS. Interestingly, heightened "perception of self" was the resilience factor uniquely associated with PCS symptoms. The final model accounted for 33% of the variance in PCS. Overall, female gender, a history of headaches, and diagnoses of ADHD and depression, and reduced "perception of self" were all predictive of greater PCS (ps < .05). Conclusion: Resilience, particularly perception of self, is a positive protective factor in the reporting of PCS. These findings highlight the importance of early identification of less resilient individuals following trauma-such as an mTBI and provide a potential rationale for the incorporation of resilience-based rehabilitation programs into the recovery process, particularly those that promote greater self-efficacy and self-competency.

Sleep and functional outcomes in children and adolescents with epilepsy: A scoping review.

AIM: In children and adolescents with epilepsy (CAWE), disturbed sleep and functional difficulties are frequently present, but their relationship is unclear. In this scoping review we aimed to explore associations between sleep and functional outcomes in CAWE. METHOD: We registered the protocol with open science framework and conducted the review according to the PRISMA Extension for Scoping Reviews. We searched Medline, Embase, PsycINFO and PubMed for original studies reporting on relations between sleep and functional outcomes (adaptive/quality of life, behavioural/mood, cognitive & academic) in CAWE. To assess the quality of studies we used an extended version of the checklist employed by Winsor and colleagues [1]. RESULTS: We identified 14 studies that included 1,785 CAWE and 1,260 control children, with a mean age of 9.94 and 10.13 years, respectively. The studies were highly heterogeneous with respect to samples, epilepsy variables, and methods used to assess sleep and functional outcomes. The quality of studies was medium. Associations between sleep and adaptive/quality of life, behavioural/mood, cognitive and academic outcomes were examined in 2, 10, 6, and 0 studies, respectively. Across studies, in CAWE, greater sleep disturbances were related to worse behavioural/mood outcomes, ranging from depression/anxiety to ADHD symptoms. Sleep disturbances did not consistently relate to cognitive outcomes, but they related to worse adaptive outcomes in both studies that examined their relationship. CONCLUSIONS: Our study provides evidence of relationship between disturbed sleep and behavioural/mood difficulties, which alerts to the need for careful evaluation and treatment of sleep disturbances in CAWE. Our study also highlights the need to examine relationships between sleep and other functional outcomes in CAWE, as studies conducted in the general population suggest that sleep disturbances may be modifiable and associated with improved functional outcomes.

Repeat testing enhances long-term verbal memory in children with epilepsy.

To (i) determine whether accelerated long-term forgetting (ALF) can be found using standardized verbal memory test materials in children with genetic generalized epilepsy (GGE) and temporal lobe epilepsy (TLE), and (ii) to establish whether ALF is impacted by executive skills and repeat testing over long delays. One hundred and twenty-three children aged 8 to 16, (28 with GGE, 23 with TLE, and 72 typically developing; TD) completed a battery of standardized tests assessing executive functioning and memory for two stories. Stories were recalled immediately and after a 30-min delay. To examine whether repeat testing impacts long-term forgetting, one story was tested via free recall at 1-day and 2-weeks, and the other at 2-weeks only. Recognition was then tested for both stories at 2-weeks. Children with epilepsy recalled fewer story details, both immediately and after 30-min relative to TD children. Compared to TD children, the GGE group, but not the TLE group, showed ALF, having significantly poorer recall of the story tested only at the longest delay. Poor executive skills were significantly correlated with ALF for children with epilepsy. Standard story memory materials can detect ALF in children with epilepsy when administered over long delays. Our findings suggest that (i) ALF is related to poor executive skills in children with epilepsy, and (ii) repeated testing may ameliorate ALF in some children.

Autobiographical memory in children with temporal lobe epilepsy.

Autobiographical memory involves the recall of personal facts (semantic memory) and re-experiencing of specific personal events (episodic memory). Although impairments in autobiographical memory have been found in adults with unilateral temporal lobe epilepsy (TLE) and attributed to compromised hippocampal integrity, it is not yet known whether this occurs in children with TLE. In the current study, 21 children with TLE and 24 healthy controls of comparable age, sex, and socioeconomic status were administered the Children's Autobiographical Interview. Compared to controls, children with TLE recalled fewer episodic details, but only when no retrieval prompts were provided. There was no difference between the groups for semantic autobiographic details. Interestingly, the number of episodic details recalled increased significantly from 6 to 16 years of age in healthy control children, but not in children with TLE. Exploratory analyses revealed that, within the group of children with TLE, epilepsy factors, including presence or absence of structural hippocampal abnormalities, did not relate to the richness of episodic recall. Our results provide first evidence of autobiographical episodic memory deficits in children with TLE.

The Parent and Child Memory Questionnaires: Convergent validity, factor structure, internal consistency, and cross-informant reliability in typically developing children.

The Parent Memory Questionnaire (PMQ) and Child Memory Questionnaire (Child MQ) assess children's memory functioning in daily activities. Their psychometric properties are largely unknown. Hence, this study aimed to establish the psychometric properties of the PMQ and Child MQ. A sample included 239 neurotypical children (113 females; Mage = 12.3 years) from Australia and Canada and their parents (n = 306; 149 females). Children also completed standardized and experimental verbal memory tests that assessed working memory, immediate recall, and recall after short (2 min, 30 min) and long (7 day) delays. Convergent validity with memory tests was low for both questionnaires, with significant, albeit small, correlations found for the WISC IV Digit Span Forward only. Exploratory factor analysis (Principal Axis Factoring with Promax rotation) of the PMQ and Child MQ yielded two (Forgetting and Remembering) and four factors (Forgetting, Remembering, Retrieval, and Episodic Memory) accounting for 49.3% and 40.6% of the variance, respectively, and reduced the number of items from 28 to 17. Both PMQ factors showed good internal consistency. Inter-rater reliability was adequate but children rated their memory as significantly poorer than their parents. The present study revealed different factorial structures for the PMQ and Child MQ. Our findings highlighted that memory questionnaires assess several aspects of memory and may complement objective memory tests in children's memory evaluation.

Accelerated long-term forgetting in children with idiopathic generalized epilepsy.

PURPOSE: The rapid forgetting of information over long (but not short) delays (accelerated long-term forgetting [ALF]) has been associated with temporal lobe epilepsy but not idiopathic generalized epilepsy (IGE). Long-term memory formation (consolidation) is thought to demand an interaction between medial temporal and neocortical networks, which could be disrupted by epilepsy/seizures themselves. The present study investigates whether ALF is present in children with IGE and whether it relates to epilepsy severity. METHODS: Sixty-one children (20 with IGE and 41 healthy controls [HC]) of comparable age, sex, and parental socioeconomic status completed neuropsychological tests, including a measure of verbal learning and recall after, short (30-min) and long (7-day) delays, and recognition. Epilepsy severity was rated by treating neurologists. KEY FINDINGS: A two-way repeated measures analysis of covariance (ANCOVA) found a significant Group x Delay interaction; the children with IGE recalled (and recognized) significantly fewer words after a long, but not short (2- and 30-min) delay relative to the HC children. Moreover, greater epilepsy severity was associated with poorer recognition. SIGNIFICANCE: This study demonstrates, to our knowledge for the first time, that children with IGE present with ALF, which is related to epilepsy severity. These findings support the notion that epilepsy/seizures themselves may disrupt long-term memory consolidation, which interferes with day-to-day functioning of children with IGE.

In-Service Training for Increasing Teachers' ADHD Knowledge and Self-Efficacy.

OBJECTIVE: The aim of this article is to evaluate the efficacy of a brief in-service training workshop at increasing primary school teachers' ADHD knowledge and sense of self-efficacy. METHOD: Teachers from 10 schools participated in the study ( n = 274) and were allocated into either an intervention or waitlist control group. Teachers' ADHD knowledge and self-efficacy were assessed following the provision of a brief training workshop on ADHD. Knowledge and self-efficacy retention were also assessed at a 1-month follow-up. RESULTS: Within the intervention group, ADHD knowledge and self-efficacy increased following the intervention (both ps < .001). Knowledge increased more than twofold, from very low to high levels, although increases in self-efficacy were more modest. Both knowledge and self-efficacy decreased at the 1-month follow-up but, nevertheless, remained higher than baseline levels ( p < .001). CONCLUSION: Results demonstrate that a brief training workshop can increase primary school teachers' ADHD knowledge and self-efficacy. Whilst increases in self-efficacy were modest, our findings suggest that a brief professional development intervention can be utilized to greatly increase teachers' ADHD knowledge, providing a cost-effective, practical solution to address this well-evidenced gap in teachers' training and knowledge about the disorder.

Longitudinal study of accelerated long-term forgetting in children with genetic generalized epilepsy: Evidence of ongoing deficits.

Accelerated long-term forgetting (ALF) is a recently described memory disorder characterised by adequate recall after short, but not long delays. Currently, the prevailing conceptualisation of ALF is of a seizure related phenomenon. The main aim of this study was to assess whether ALF subsides as epilepsy severity and seizures abate in children with genetic generalized epilepsy (GGE). Eighteen children with GGE were compared over time to 29 healthy controls on a range of cognitive measures. The primary outcome was a modified version of the California Verbal Learning Test for Children with a long delay (seven day) recall component. At approximately two years follow up, ALF was apparent, although epilepsy severity subsided and seizures resolved in many children. This result contrasts with the dominant conceptualisation of ALF being a seizure related phenomenon. Moreover, at follow-up, worse recall at the long delay was related to greater epilepsy severity at baseline and earlier age of seizure onset, but not to being seizure free at follow-up. While at follow-up worse recall at the long delay related to the worse baseline recall at the long delay, this recall did not relate to scores obtained on standardised memory tests at baseline. Our study suggests that ALF may not be seizure related and identifies factors associated with risk of ALF in children with GGE.

Selective, age-related autobiographical memory deficits in children with severe traumatic brain injury.

OBJECTIVES: Autobiographical memory (AM) is a complex function that involves re-experiencing of past personal events (episodic memory) scaffolded by personal facts (semantic memory). While AM is supported by a brain network and cognitive skills that are vulnerable to disruption by child traumatic brain injury (TBI), AM has not been examined in this patient population. DESIGN: Cross-sectional study. METHODS: Participants included children with severe closed TBI (n = 14) and healthy control (NC) children (n = 20) of comparable age, sex, and socioeconomic status. Participants completed (1) the Child Autobiographical Interview (Willoughby et al., 2012, Front. Psychol., 3, 53), which required recall of autobiographical events and distinguished episodic (internal) from non-episodic (external) details, and self-rating of event phenomenological qualities, and (2) a battery of neuropsychological tests. RESULTS: Children with TBI recalled significantly fewer internal details relative to NCs, but the between-group difference was eliminated when specific probes were provided. The groups did not differ in either recall of external details or in ratings of events' phenomenological qualities. The gap between the groups in recall of internal details increased with age, as the greater number of internal details was associated with older age in the NC group, but not in the TBI group. Poorer verbal memory and lower IQ were related to recall of fewer internal details in the TBI group. CONCLUSIONS: This study unveils, to our knowledge for the first time, that severe child TBI is associated with a selective deficit in autobiographical memory that involves episodic, but spares semantic details, and identifies the risk factors for this impairment.

Accelerated long-term forgetting and behavioural difficulties in children with epilepsy.

Patients with epilepsy have been shown to exhibit a range of memory deficits, including the rapid forgetting of newly-learned material over long, but not short, delays (termed accelerated long-term forgetting; ALF). Behavioural problems, such as mood disorders and social difficulties, are also overrepresented among children with epilepsy, when compared to patients with other chronic diseases and the general population. We investigated whether ALF was associated with behavioural or psychosocial deficits in children with epilepsy. Patients with either idiopathic generalised epilepsy (IGE; n = 20) or temporal lobe epilepsy (TLE; n = 23) and healthy controls (n = 53) of comparable age, sex, and socioeconomic status completed a battery of neuropsychological tests, including a list-learning task that required recall after short (30-min) and long (7-day) delays. Parents or guardians of all participants also completed the Child Behavior Checklist (CBCL). Compared to control participants, patients with IGE and TLE had higher scores on all but one of the indices of behavioural problems. When patients with IGE and TLE were merged into a single group, they were found to have negative correlations between 7-day recall and internalising, social and total problem behaviour domains, where poorer 7-day recall was associated with behavioural problems of greater severity. These findings suggest that impaired episodic recall is associated with behavioural deficits, including social problems, which are routinely observed in patients with epilepsy.

Accelerated Long-Term Forgetting Is Not Epilepsy Specific: Evidence from Childhood Traumatic Brain Injury.

Accelerated long-term forgetting (ALF) is characterized by adequate recall after short, but not long delays. ALF is not detected by standardized neuropsychological memory tests. Currently, the prevailing conceptualization of ALF is of a temporal lobe seizure-related phenomenon. Nevertheless, Mayes and colleagues (2003) proposed that ALF may occur when any of the components of the brain network involved in long-term memory formation, or their interaction, is disrupted. This disruption does not have to be caused by temporal lobe seizures for ALF to occur. Here, we investigate this possibility in a group of school-age children who have sustained traumatic brain injury (TBI) (n = 28), as TBI typically disrupts the brain network that is important for long-term memory formation and recall. Healthy control children (n = 62) also participated. Contrary to the dominant conceptualization of ALF being a seizure-related phenomenon, children with TBI showed ALF. Sustaining a severe TBI and diffuse subcortical damage was related to ALF. Individually, 8 of the 13 children with severe TBI presented with ALF. ALF would remain undetected on standardized testing in six of these eight children. One child had the opposite pattern of dissociation, an impaired score on standardized testing, but an average long-term memory score. This is the first study, to our knowledge, to show ALF in patients with TBI, which has remained undiagnosed and untreated in this patient population. Our study also challenges the dominant hypothesis of ALF being a temporal lobe seizure-related phenomenon, and raises a possibility that short-term and long-term memory systems may be independent.

Ecstasy and the concomitant use of pharmaceuticals.

Recent anecdotal evidence suggests that it is becoming increasingly popular among ecstasy users to attempt to negate certain side-effects or enhance the drug experience through the concomitant use of pharmaceutical drugs or supplements. This study was designed to explore the practice of deliberately using pharmaceuticals for any reason in association with ecstasy and related drug (ERD) use. A cross sectional survey was conducted with 216 adults who had used ecstasy at least once in the previous 6 months. Generally, this sample was young, well educated, and likely to be in some form of paid employment. Males were slightly overrepresented within the sample. About one quarter of the sample had deliberately taken a pharmaceutical substance for its putative effects on the euphoric effects of, or recovery from, ecstasy use. Those who reported using pharmaceuticals were significantly more likely to be male, had more 'apparent' years of use, and were more likely to have injected ERDs. As a result, there appears to be a need for harm reduction information for ecstasy users regarding the risks associated with the mixture of ERDs with pharmaceuticals and supplements. Particular attention should be paid to informing users of the potentially fatal serotonin syndrome that is likely to arise from combining serotonin-enhancing substances, such as ecstasy or SSRI and MAOI groups of antidepressants.

The consumption of alcohol by Australian adolescents: a comparison of revenue and expenditure.

AIMS: To estimate (i) Australian government taxation revenue collected from the consumption of alcohol by adolescents and (ii) the amount spent by the government on interventions aimed at educating adolescents about the potential dangers of alcohol use. DESIGN: Secondary data analysis. SETTING: Australia. FINDINGS: Australian adolescents (aged between 12 and 17 years, inclusive) spent approximately US dollars 217 million on alcoholic beverages in 2002, netting the Australian government approximately US dollars 112 million in tax revenue. This resulted in an average of US dollars 195 earned in tax per adolescent drinker. It is estimated that the Government spent approximately US dollars 17 million on adolescent drinking interventions in 2002, equating to an expenditure of about US dollars 10.51 per adolescent on the delivery of alcohol interventions. For every dollar spent on alcohol interventions aimed at adolescents, it is estimated that the government receives around US dollars 7 in alcohol tax revenue. CONCLUSIONS: A substantial disparity exists between the amount of tax revenue received by the Australian government from adolescent drinkers and the overall amount spent in attempting to prevent and relieve some of the problems associated with adolescent problem drinking.

Autobiographical memory in children with Idiopathic Generalised Epilepsy.

Autobiographical memory involves the recall of both personal facts (semantic memory) and the re-experiencing of past personal events (episodic memory). The recall of autobiographical episodic details has been associated with a specific network, which involves the prefrontal and medial temporal lobes, in addition to posterior regions of the brain. Seizure activity has been previously shown to disrupt the consolidation of newly-learned information into long-term memory, but it is not yet known whether primary generalised seizures alone are also associated with deficits in the recall of autobiographical memories. Here we examined this recall in children who experience generalised rather than localisation-related seizures: children with Idiopathic Generalised Epilepsy (IGE). In this study, 18 children with IGE and 42 healthy controls of comparable age (6-16 years), sex and socio-economic status were administered the Children's Autobiographical Interview (CAI). Compared with controls, children with IGE recalled significantly fewer episodic details, even when retrieval prompts were provided. In contrast, no group difference was found for the recall of semantic autobiographic details. Within the IGE group, hierarchical regression analyses showed that patient age and earlier age of diagnosis were significantly related to the recall of episodic autobiographical details over different conditions of the CAI, explaining up to 37% of variance. To our knowledge, this study provides the first evidence of autobiographical episodic memory deficits in patients with primary generalised seizures. As no evidence of localisation-related epilepsy is apparent in patients with IGE, our findings suggest that generalised seizures alone, especially when developed at an early age, could compromise memories for personally-experienced events.
