Tan M, Boston R, Cook MJ, D'Souza WJ. Risk factors for injury in a community-treated cohort of patients with epilepsy in Australia. Epilepsia 2019; 60:518-526. [PMID: 30720862 DOI: 10.1111/epi.14659] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 01/05/2019] [Accepted: 01/07/2019] [Indexed: 12/01/2022]
Abstract
OBJECTIVE There remains a paucity of knowledge regarding specific epilepsy-related risk factors for accidents and injuries in people with epilepsy. Injury studies in people with epilepsy are overrepresented, with tertiary based populations that are prone to bias from severe disease. This study aims to assess the contribution of epilepsy-related risk factors to injuries in a community-based cohort. METHODS We performed a retrospective nested case-control study on patients recruited into the Tasmanian Epilepsy Register (TER) from July 1, 2001 to June 30, 2002. The TER is a community-based cohort of patients with epilepsy in Tasmania, Australia, recruited from the national prescription database and interviewed for epilepsy diagnosis, injuries, and risk factors using validated questionnaires with diagnosis made by an epilepsy specialist. The primary outcome measures were lifetime and recent 12-month injury. Multivariate logistic regression with multiple imputation modeling responder nondisclosure was performed, adjusting for age, gender, region, socioeconomic status, seizure frequency, and epilepsy duration. RESULTS A total of 819 patients with epilepsy were included in this study. Ten percent of patients experienced an injury in the preceding year. Before adjusting for seizure frequency, any seizure over the past 12 months was associated with recent injury (adjusted odds ratio [OR] = 7.90, 95% confidence interval [CI] = 4.17-14.96). Impaired awareness, cluster seizures, sleep-only seizures, and convulsive seizure were characteristics found to significantly influence injuries irrespective of seizure frequency. Although a warning appeared initially protective for recent injuries (OR = 0.39, 95% CI = 0.22-0.69), this was entirely explained by seizure frequency, with the effect becoming nonsignificant. SIGNIFICANCE Likely due to their unpredictable nature, seizures expose patients with epilepsy to a high risk of life-threatening injury. These findings emphasize the importance of seizure freedom for maximizing the safety of patients with epilepsy.

Abstract
Objective To investigate whether adolescents with epilepsy are at increased risk of having self-reported eating disorder symptoms and poor quality diet compared to young people from the general population. Methods We used data from the Health Profile for Children and Youth in Akershus Study, a cross-sectional population-based study based on a voluntary self-reported questionnaire. There were 19,995 participants (response rate 85%) aged 13-19 years; 247 (1.2%) reported a lifetime diagnosis of epilepsy. Odds ratios (OR) and 95% confidence intervals (CI) for eating disorders, unhealthy diet, dieting, satisfaction with looks, and participation in sports were estimated by using a logistic regression model. All estimates were adjusted for single parents and poor family economy. Results Children and adolescents with epilepsy had more eating disorders than their peers (OR 1.8, CI 1.0-3.0, p = 0.03). They were less satisfied with their own appearance (OR 0.7, CI 0.5-0.9, p = 0.02), and they eat more unhealthily (OR 1.7, CI 1.3-2.2, p = 0.001). Males with epilepsy were more likely to have been dieting (OR 3.1, CI 1.2-7.9, p = 0.02) and less satisfied with their own appearance (OR 0.4, CI 0.3-0.7, p < 0.001). Females with epilepsy were more likely to eat unhealthily (OR 1.7, CI 1.1-2.5, p = 0.01). Significance Adolescents with epilepsy are at increased risk of having eating disorder symptoms. They eat less healthily and are less satisfied with their looks. Health workers should be aware of this and bring diet and lifestyle into the dialogue with young people with epilepsy.

Abstract
OBJECTIVE The aim of this study was to investigate birth rates and use of hormonal contraception in different age groups among women with epilepsy (WWE) in comparison to women without epilepsy. MATERIALS AND METHODS Demographic data and medical information on more than 25,000 pregnant women (40,000 births), representing 95% of all pregnancies in Oppland County, Norway, were registered in the Oppland Perinatal Database in the period 1989-2011. Data were analyzed with respect to epilepsy diagnoses, and 176 women with a validated epilepsy diagnosis (303 pregnancies) were identified. Age-specific birth rates in these women were estimated and compared with age-specific birth rates in women without epilepsy in the same county. RESULTS In WWE over 25 years of age, birth rates were significantly lower than in those of the same age group without epilepsy. In women below 20 years of age, birth rates were similar in those with and without epilepsy. The use of hormonal contraceptives prior to pregnancy was lower among WWE under 25 years than in the corresponding age group without epilepsy. CONCLUSIONS Health professionals who counsel WWE who are of fertile age should be aware of the strongly reduced birth rates in WWE over 25 years of age, and the lower rates of use of contraceptives among young WWE.

Abstract
OBJECTIVES In comparison with controls, youth with epilepsy (YWE) have greater psychosocial problems. However, information about their sexual behavior is sparse. We have performed a large, population-based questionnaire study to examine differences in sexual behavior between YWE and controls. METHODS A randomly chosen cohort of youth (13-19 years) from Akershus county, Norway (n=19,995) was asked to complete a questionnaire anonymously with questions on epilepsy and sexual activity. RESULTS The response rate was 85%. Two hundred forty-seven participants reported having or having had epilepsy, i.e., a lifetime epilepsy prevalence of 1.2%. Compared with controls, a higher proportion of YWE reported having had sexual intercourse (43.6% vs. 35.3%, p=0.009). The mean age at sexual debut was significantly lower in YWE than in controls (14.0 years vs. 15.0 years, p<0.001), and this was particularly marked among boys. A higher proportion of YWE reported not having used contraceptives at their last sexual intercourse compared with controls (31.6% vs. 22.3%, p=0.03). Ten percent of YWE, compared with 2% of the controls, reported that they had been forced into their first sexual intercourse. CONCLUSION In YWE, some aspects of sexual behavior differ from those of their peers, with earlier sexual debut and less frequent use of contraceptives. More attention should be directed toward this subject, aiming at avoiding unwanted pregnancies and potential emotional traumas in this already vulnerable patient group.

Abstract
Mutations in the voltage-gated sodium channel gene SCN1A are responsible for a number of epilepsy disorders, including genetic epilepsy with febrile seizures plus (GEFS+) and Dravet syndrome. In addition, dysfunction in SCN1A is increasingly being linked to neuropsychiatric abnormalities, social deficits and cognitive disabilities. We have previously reported that mice heterozygous for the SCN1A R1648H mutation identified in a GEFS+ family have infrequent spontaneous seizures, increased susceptibility to chemically and hyperthermia-induced generalized seizures and sleep abnormalities. In this study, we characterized the behavior of heterozygous mice expressing the SCN1A R1648H mutation (Scn1a(RH/+)) and the effect of stress on spontaneous and induced seizures. We also examined the effect of the R1648H mutation on the hypothalamic-pituitary-adrenal (HPA) axis response. We confirmed our previous finding that Scn1a(RH/+) mutants are hyperactive, and also identified deficits in social behavior, spatial memory, cued fear conditioning, pre-pulse inhibition and risk assessment. Furthermore, while exposure to a stressor did increase seizure susceptibility, the effect seen in the Scn1a(RH/+) mutants was similar to that seen in wild-type littermates. In addition, Scn1a dysfunction does not appear to alter HPA axis function in adult animals. Our results suggest that the behavioral abnormalities associated with Scn1a dysfunction encompass a wider range of phenotypes than previously reported and factors such as stress exposure may alter disease severity in patients with SCN1A mutations.

Abstract
AIM To determine the distribution and risk characteristics of comorbid neurodevelopmental and mental health comorbidities among children and adolescents (6-18y) with epilepsy or migraine (i.e. a neurological condition with shared features and potential etiology) compared with lower extremity fracture (LEF). METHOD This case-control study involved a subset analysis of surveillance data in South Carolina, USA. Hospital admission, outpatient, and emergency department visits for individuals with an International Classification of Disease, 9th revision Clinical Modification diagnosis of epilepsy (n=6730; 54.5% females, 45.5% males; mean age [SD] 14y 2mo [4y 5mo]); migraine (n=10 495; 74.5% females, 25.5% males; 15y 6mo [2y 6mo]), or LEF (n=15 305; 40.3% females, 59.7% males; 13y 11mo [2y 11mo]) from January 1 2000 to December 31 2011 were identified. The association of epilepsy, migraine, or LEF with any mental health comorbidity was evaluated with univariate and multivariate polytomous logistic regression. RESULTS Comorbidities were highly prevalent in children and adolescents, with epilepsy with a rate of 29.7% (95% confidence interval [CI]: 28.6-30.8) for mental health comorbidities and 30.8% (95% CI: 29.7-31.9) for neurodevelopmental comorbidities. The odds of mental health comorbidity was 2.20 (95% CI: 2.02-2.39) for children and adolescents with epilepsy and 1.60 (95% CI: 1.48-1.73) for migraine, in reference to children and adolescents with LEF after adjusting for potential confounders. Prevalence and risk for specific comorbidities are presented. INTERPRETATION Neuropathophysiological and psychosocial factors specific to epilepsy may provide more risk for adolescents with epilepsy compared to migraine.

Abstract
BACKGROUND From a population based study of epilepsy in Swedish children a subgroup designated well-functioning with an epilepsy diagnosis in 1997 was worked up from a medical point of view 10 years later. AIM To describe the psychological and social outcome in this subgroup. METHODS Thirty-one patients aged 11-22 years and their parents/partners responded to a questionnaire according to Achenbach System of Empirically Based Assessment (ASEBA) to evaluate behavioural and emotional problems, and social competence. RESULTS Active epilepsy, diagnosed in 32%, was related to attention problems, somatic complaints, and school problems. Polytherapy, used in 16%, was related to attention problems and aggressive behaviour. School problems were found in six of seven children younger than 18 years. Internalizing, externalizing, and 'other' syndromes were found in 29% of the individuals, but a grouping of these syndromes in the clinical range only in two (6.5%), a girl with generalized tonic-clonic seizures alone, and a boy with structural focal epilepsy. Both had active epilepsy and were treated with polytherapy. All ten individuals with Rolandic epilepsy were classified as normal. The answers to the ASEBA questionnaire of individuals and parents/partners were inconsistent, and parents generally stated more problems than the individuals. SUMMARY This 10-year follow-up study of psychological and social outcome in well-functioning children and adolescents with childhood onset epilepsy shows some emotional, behavioural, and social problems. Thus, early information to increase knowledge about epilepsy and associated psychological co-morbidities in order to decrease risk of low self-esteem, social anxiety, and depression later in life is of importance.

Abstract
This review examines the neurodevelopmental contribution to the cognitive and behavioural complications of epilepsy. Following a brief review of the lifespan complications of childhood epilepsies, attention turns to cognitive, psychiatric and social correlates of childhood epilepsies reported in population-based and tertiary care studies. The focus then becomes the neurobehavioural status of children with new-onset epilepsy; a point in time not confounded by the effects of years of recurrent seizures, medications, and social reactions to epilepsy. Recent research shows that abnormalities in cognition, brain structure and behaviour are present at or near the time of diagnosis. Further, careful history taking indicates that neurobehavioural problems may be present in advance of the first seizure suggesting the potential influence of epileptogenesis, antecedent neurodevelopmental abnormalities, genetic and environmental susceptibilities, and other risk factors. This becomes the substrate upon which to characterise the effects of epilepsy and its treatment on subsequent neurodevelopment. The review concludes with suggestions for future clinical care and research.
