Abstract
The impact of epilepsy is multifaceted and extensive on its effects. The occurrence of seizures is unpredictable and often dangerous, increasing the risk of injury, hospitalization and mortality, and adversely affecting a patient's mental health, often resulting in anxiety, depression or cognitive impairment. Seizures can also result in stigmatization and social exclusion, with detrimental effects on an individual's confidence and self-esteem. However, the burden of epilepsy extends beyond the effects of seizures themselves. In particular, individuals with epilepsy are significantly more likely to have medical or psychiatric comorbidities than those without epilepsy, and comorbidity in patients with epilepsy has been shown to be strongly correlated with negative impacts on subjective health status and quality of life (QoL). In addition, antiepileptic drug (AED) treatment is commonly associated with side effects, which further impair patients' QoL. Patient surveys provide valuable insights into what matters to patients in their daily lives and highlight important discrepancies between the perceptions of patients and their physicians. For example, survey data show that physicians underestimate the number of patients experiencing AED side effects and the impact of these on patients. Screening questionnaires can help physicians to quickly identify problems with treatment side effects; also, to recognize comorbidities such as depression that are otherwise difficult to identify in a time-limited consultation. Ultimately, successful management of epilepsy requires a holistic approach to care, with treatment tailored to the individual patient's needs; this can only be achieved through effective doctor-patient communication and the full involvement of a multidisciplinary care team.

Abstract
BACKGROUND The prevalence of epilepsy in sub-Saharan Africa seems to be higher than in other parts of the world, but estimates vary substantially for unknown reasons. We assessed the prevalence and risk factors of active convulsive epilepsy across five centres in this region. METHODS We did large population-based cross-sectional and case-control studies in five Health and Demographic Surveillance System centres: Kilifi, Kenya (Dec 3, 2007-July 31, 2008); Agincourt, South Africa (Aug 4, 2008-Feb 27, 2009); Iganga-Mayuge, Uganda (Feb 2, 2009-Oct 30, 2009); Ifakara, Tanzania (May 4, 2009-Dec 31, 2009); and Kintampo, Ghana (Aug 2, 2010-April 29, 2011). We used a three-stage screening process to identify people with active convulsive epilepsy. Prevalence was estimated as the ratio of confirmed cases to the population screened and was adjusted for sensitivity and attrition between stages. For each case, an age-matched control individual was randomly selected from the relevant centre's census database. Fieldworkers masked to the status of the person they were interviewing administered questionnaires to individuals with active convulsive epilepsy and control individuals to assess sociodemographic variables and historical risk factors (perinatal events, head injuries, and diet). Blood samples were taken from a randomly selected subgroup of 300 participants with epilepsy and 300 control individuals from each centre and were screened for antibodies to Toxocara canis, Toxoplasma gondii, Onchocerca volvulus, Plasmodium falciparum, Taenia solium, and HIV. We estimated odds ratios (ORs) with logistic regression, adjusted for age, sex, education, employment, and marital status. RESULTS 586,607 residents in the study areas were screened in stage one, of whom 1711 were diagnosed as having active convulsive epilepsy. Prevalence adjusted for attrition and sensitivity varied between sites: 7·8 per 1000 people (95% CI 7·5-8·2) in Kilifi, 7·0 (6·2-7·4) in Agincourt, 10·3 (9·5-11·1) in Iganga-Mayuge, 14·8 (13·8-15·4) in Ifakara, and 10·1 (9·5-10·7) in Kintampo. The 1711 individuals with the disorder and 2032 control individuals were given questionnaires. In children (aged <18 years), the greatest relative increases in prevalence were associated with difficulties feeding, crying, or breathing after birth (OR 10·23, 95% CI 5·85-17·88; p<0·0001); abnormal antenatal periods (2·15, 1·53-3·02; p<0·0001); and head injury (1·97, 1·28-3·03; p=0·002). In adults (aged ≥18 years), the disorder was significantly associated with admission to hospital with malaria or fever (2·28, 1·06-4·92; p=0·036), exposure to T canis (1·74, 1·27-2·40; p=0·0006), exposure to T gondii (1·39, 1·05-1·84; p=0·021), and exposure to O volvulus (2·23, 1·56-3·19; p<0·0001). Hypertension (2·13, 1·08-4·20; p=0·029) and exposure to T solium (7·03, 2·06-24·00; p=0·002) were risk factors for adult-onset disease. INTERPRETATION The prevalence of active convulsive epilepsy varies in sub-Saharan Africa and that the variation is probably a result of differences in risk factors. Programmes to control parasitic diseases and interventions to improve antenatal and perinatal care could substantially reduce the prevalence of epilepsy in this region.

Abstract
AIM To examine self-report data on seizure-related injuries and hospitalizations. METHOD We analyzed data from the 2010 Australian Epilepsy Longitudinal Survey, distributed to registrants on the Australian Epilepsy Research Register. 343 responses were received (55% response rate), providing insight into experiences of living with seizures. This article examines self-report data on injuries related to seizures and hospitalizations. RESULTS 64% of those reporting injuries required hospital treatment. Respondents with seizure-related injuries had significantly earlier seizure onset, with risk of injury related to myoclonic and atonic seizures and currently taking 3 or more AEDs. Soft tissue injuries were the most frequently reported (85%), with 27% indicating facial injuries. CONCLUSIONS The high rate of hospitalizations largely for soft tissue injuries suggests that access to more appropriate care was not available. Further research into care-seeking behavior by Australians suffering injury following seizure is required. Additionally, awareness of injury risks is important for appropriate self-management of epilepsy.

Abstract
Impaired consciousness in epilepsy has a significant negative impact on patients' quality of life yet is difficult to study objectively. Here, we develop an improved prospective Responsiveness in Epilepsy Scale-II (RES-II) and report initial results compared with the earlier version of the scale (RES). The RES-II is simpler to administer and includes both verbal and non-verbal test items. We evaluated 75 seizures (24 patients) with RES and 34 seizures (11 patients) with RES-II based on video-EEG review. The error rate per seizure by test administrators improved markedly from a mean of 2.01 ± 0.04 with RES to 0.24 ± 0.11 with RES-II. Performance during focal seizures showed a bimodal distribution, corresponding to the traditional complex partial vs. simple partial seizure classification. We conclude that RES-II has improved accuracy and testing efficiency compared with the original RES. Prospective objective testing will ultimately lead to a better understanding of the mechanisms of impaired consciousness in epilepsy.

Abstract
In this study, we present long-term results from patients with medial temporal lobe (MTL) epilepsy treated with deep brain stimulation (DBS). Since 2001, 11 patients (8M) with refractory MTL epilepsy underwent MTL DBS. When unilateral DBS failed to decrease seizures by > 90%, a switch to bilateral MTL DBS was proposed. After a mean follow-up of 8.5 years (range: 67-120 months), 6/11 patients had a ≥ 90% seizure frequency reduction with 3/6 seizure-free for > 3 years; three patients had a 40%-70% reduction and two had a < 30% reduction. In 3/5 patients switching to bilateral DBS further improved outcome. Uni- or bilateral MTL DBS did not affect neuropsychological functioning. This open study with an extended long-term follow-up demonstrates maintained efficacy of DBS for MTL epilepsy. In more than half of the patients, a seizure frequency reduction of at least 90% was reached. Bilateral MTL DBS may herald superior efficacy in unilateral MTL epilepsy.

Abstract
A seizure prediction algorithm is proposed that combines novel multivariate EEG features with patient-specific machine learning. The algorithm computes the eigenspectra of space-delay correlation and covariance matrices from 15-s blocks of EEG data at multiple delay scales. The principal components of these features are used to classify the patient's preictal or interictal state. This is done using a support vector machine (SVM), whose outputs are averaged using a running 15-minute window to obtain a final prediction score. The algorithm was tested on 19 of 21 patients in the Freiburg EEG data set who had three or more seizures, predicting 71 of 83 seizures, with 15 false predictions and 13.8 h in seizure warning during 448.3 h of interictal data. The proposed algorithm scales with the number of available EEG signals by discovering the variations in correlation structure among any given set of signals that correlate with seizure risk.

Abstract
Children with disabilities that limit mobility are at increased risk for osteoporosis. In the United States, 10 million people have osteoporosis and 34 million people are estimated to be at risk of acquiring this condition. Typically, bone fragility and osteoporosis have been associated with older adults; however, these problems can also affect children. The childhood and adolescent years are critically important in producing healthy bone mass. Yet cerebral palsy and epilepsy, which are both chronic disorders that frequently coexist, are predictors of muscular and skeletal compromise. Nurse practitioners should be aware of recommendations for promoting and achieving optimal bone health in children with these disabilities and screening patients who are at risk of sustaining fractures.

Abstract
Central cord syndrome (CCS) is extremely rare as a direct consequence of generalized epileptic seizure. CCS is associated with hyperextension of the spinal cord and has characteristic radiologic findings including posterior ligamentous injury and prevertebral hyperintensity following magnetic resonance imaging (MRI). We experienced the case of a 25-year-old man who suffered CCS after status epilepticus. Cervical spinal MRI revealed high signal intensity at the C1 level but with no signal or structural changes in other sites. After rehabilitation management, the patient significantly improved on the ASIA (American Spinal Injury Association) motor scale and bladder function. We proposed that epilepsy related CCS may be caused by muscle contractions during generalized seizure, which can induce traction injury of the spinal cord or relative narrowing of spinal canal via transient herniated nucleus pulposus or transient subluxation of vertebra. We also suggest CCS without radiologic findings of trauma has good prognosis compared with other CCS.

Abstract
This study evaluated the resource use of patients with epilepsy in the German district of Marburg-Biedenkopf. A cross-sectional cohort of consecutive adults with epilepsy, irrespective of seizure severity, duration of illness and epilepsy syndrome, was investigated in all health-care sectors. Costs of inpatient and outpatient treatment were derived from billing data of participating hospitals and office-based physicians. Data on socioeconomic status, course of epilepsy and further direct and indirect costs were recorded using patient questionnaires. We enrolled 366 patients from the district of Marburg-Biedenkopf and calculated annual epilepsy-specific costs of €7738 per patient. Direct costs contributed 31.1% (€2406) and indirect costs 68.9% (€5332) of the total costs. Direct medical costs were mainly due to hospitalization (33.2% of total direct costs) and anticonvulsants (26.7%). Costs of admissions were due to status epilepticus (24.4%), video-EEG monitoring (14.8%), newly diagnosed patients (14.4%) and seizure-related injuries (8.8%). Indirect costs were mainly due to early retirement (38.0%), unemployment (35.9%) and days off due to seizures (26.2%). The mean costs of epilepsy found in our study were lower than those found in studies conducted at European epilepsy centers due to the inclusion of patients in all health-care sectors.

Abstract
OBJECTIVES The aim of this study was to investigate the quality of life (QOL) in people with epilepsy (PWE) living in Khartoum State, Northern Sudan. The region offers a model of urban and suburban communities in developing countries. METHODS A cross-sectional study was carried out in the neurology clinic of Khartoum State Hospital and Omer Ibn Alkhatab Health Center in the suburb of Khartoum State. We interviewed PWE living in the city, the suburbs and adjacent villages. Our subjects were known to have been on antiepileptic drugs (AED) for at least 6 months. The impact of epilepsy on the QOL was assessed in the clinic using a 23-item questionnaire with graded scales and check-lists to explored demographic characteristics, seizure control, adverse effects of antiepileptic medication, physical harm, social and psychological impact and stigmatization. RESULTS Fifty-two females and 48 males between the ages of 10 and 80 years were interviewed. Sixty percent of participants were between 20 and 39 years of age. While on AED treatment, 63% developed at least one seizure at any given time, 49% in the past 6 months and 27% in the past week. Twenty six percent experienced one or more side effect of AEDs. A significant number of respondents admitted that epilepsy had a negative impact on several aspects of their daily life activities, education and social functioning. Of individuals eligible for work, 17% were unemployed or had their job terminated because of epilepsy. Relationships with spouses were affected in 20 % of cases. Fifteen percent felt stigmatized by their illness. None of the participants had received any formal health education or counseling about epilepsy. CONCLUSION Epilepsy has a significant impact on several aspects of QOL, particularly physical injury and socioeconomic functioning affecting PWE living in Khartoum State. Poor seizure control, a risk factor for impaired QOL, was common. The overall perceptions of QOL and self satisfaction as stated by our PWE was more favorable when compared to those in developed countries and the Gulf. Nevertheless, this could be more reflective of social circumstances and better seizure control, health education and counseling for PWE and their families is still encouraged and recommended.

Abstract
OBJECTIVE Motor vehicle accidents direct legislators to ensure pubic safety. We attempted to characterize and quantify driving risk in patients with seizures (PWS). METHODS We delivered 12-question surveys to 287 consecutive PWS at an epilepsy clinic in Florida. Illegal and disobedient driving practices were analyzed. RESULTS Eighty-three of 236 (35.2%) PWS were eligible to drive and 62.3% were ineligible with a seizure in <6 months (P<0.001, 95% CI: 0.57-0.70). Among the ineligible responders, 23.8% (35/147) of ineligible responders were illegally driving (14.83% of cohort); 11.86% (28/236) of PWS were disobedient refusing to obey the law, and 8.9% (21/236) of PWS were defiant and knew the law. Sadness (75/236, 31.8%) was the most common reaction to restriction, but disobedient PWS were angry (10/28, 35.7%). CONCLUSION Overall, a small number of PWS are disobedient and illegally driving. A targeted approach to high-risk drivers with repeated verbal and supplemental driving information may help avoid unnecessary universal physician reporting for PWS.

Abstract
PURPOSE Impaired consciousness in epileptic seizures has a major negative impact on patient quality of life. Prior work on epileptic unconsciousness has mainly used retrospective and nonstandardized methods. Our goal was to validate and to obtain initial data using a standardized prospective testing battery. METHODS The responsiveness in epilepsy scale (RES) was used on 52 patients during continuous video-electroencephalography (EEG) monitoring. RES begins with higher-level questions and commands, and switches adaptively to more basic sensorimotor responses depending on patient performance. RES continues after seizures and includes postictal memory testing. Scoring was conducted based on video review. KEY FINDINGS Testing on standardized seizure simulations yielded good intrarater and interrater reliability. We captured 59 seizures from 18 patients (35% of participants) during 1,420 h of RES monitoring. RES impairment was greatest during and after tonic-clonic seizures, less in partial seizures, and minimal in auras and subclinical seizures. In partial seizures, ictal RES impairment was significantly greater if EEG changes were present. Maximum RES impairment (lowest ictal score) was also significantly correlated with long postictal recovery time, and poor postictal memory. SIGNIFICANCE We found that prospective testing of responsiveness during seizures is feasible and reliable. RES impairment was related to EEG changes during seizures, as well as to postictal memory deficits and recovery time. With a larger patient sample it is hoped that this approach can identify brain networks underlying specific components of impaired consciousness in seizures. This may allow the development of improved treatments targeted at preventing dysfunction in these networks.

Abstract
Epilepsy is responsible for falls that are not systematically associated with seizures and that therefore suggest postural impairment. There are very few studies of postural control in patients with epilepsy and none of them focus on temporal lobe epilepsy (TLE), although part of the vestibular cortex is located in the temporal cortex. The aim of this study was to evaluate the characteristics of postural control in a homogeneous population of patients with complex partial TLE. Twenty-six patients with epilepsy and 26 age-matched healthy controls underwent a sensory organization test combining six conditions, with and without sensory conflicting situations. Patients with epilepsy displayed poorer postural control, especially in situations where vestibular information is necessary to control balance. In addition to potential antiepileptic drug side effects, vestibular dysfunction could be related to the temporal pathology. Our study allows for a better understanding of the mechanism underlying falls in this population of patients.

Abstract
An adequate early treatment of a long-lasting convulsive seizure is critical in reducing potential morbidity, and in particular, brain damage. In pre-hospital settings the use of benzodiazepines should become standard. Nowadays, rectal diazepam is used frequently, but midazoloam and lorazepam are becoming more popular, both being given either intranasally or orally. The buccal route is to be preferred because of its easy use and high efficacy. A generally accepted policy for early treatment of convulsive seizures is a crucial issue in the elaboration of an overall treatment plan for the child with epilepsy. Such a plan should include instruction and education of the parents and the caregivers surrounding the child.

Abstract
PURPOSE Ictal asystole (IA) and ictal bradycardia (IB) are rare autonomic symptoms during epileptic seizures and may be potentially life-threatening. Guidelines for the care of these patients are missing. The aim of this multicenter study was to evaluate the management and long-term outcome in patients with IA and IB. PATIENTS AND METHODS All patients with IA and IB were included from four epilepsy centers (Bielefeld, Kork, Marburg, and Zürich) from 2002 until 2009. Using a standardized assessment form, clinical data, treatment decisions, and outcomes were extracted from patient charts and simultaneous electroencephalography/electrocardiography (EEG/ECG) recordings. KEY FINDINGS Seizures with IA or IB were identified in 16 patients. In all patients an associated temporal seizure pattern was recorded and in 15 patients, sudden falls, fainting, or trauma was previously reported or recorded during the monitoring. In three patients (18.8%) diagnosis of focal epilepsy was newly established and anticonvulsive treatment was initiated. Two patients with refractory epilepsy underwent epilepsy surgery. In seven patients (43.8%) a cardiac pacemaker was implanted. In 14 of 16 treated patients, seizure freedom (n = 5) or absence of sudden falls, fainting, or trauma (n = 9) could be achieved. Two patients denied epilepsy surgery as well as a pacemaker and continue to have frequent falls and trauma. SIGNIFICANCE Our study demonstrates that epilepsy surgery and antiepileptic drugs may lead to sustained freedom of seizures as well as ictal syncope. In drug-resistant patients not suitable for epilepsy surgery, implantation of a cardiac pacemaker may prevent sudden falls as well as trauma. Based on our results and previously reported cases we propose a treatment algorithm.

Abstract
OBJECTIVE The goal of this study was to assess the characteristics and risk factors for injuries caused by seizures in older persons. METHODS All patients aged 65 years or older having injuries secondary to seizures between July 1, 1999, and June 30, 2009, were identified through the diagnostic coding system. RESULTS Over the assessment period, a total of 615 patient episodes of seizures were recorded. Nineteen seizure-related injury events occurred in 18 persons with a total of 31 injuries. In the control group, 34 non-seizure-related injuries that were not seizure related occurred in 27 patients (28 patient episodes) (P = 0.21). The majority of injuries in both groups resulted from falls. Fifty-three percent of seizures occurred indoors, and the majority of seizures were generalized tonic-clonic seizures. Of the seizure-related injury events, 8 (42%) were single injuries, and 11 (61%) were multiple injuries. The predominant injuries were soft tissue injuries (55%), fractures (35%), and head injuries (10%). The groups did not differ significantly with respect to fractures (P = 0.06) or soft tissue injuries with lacerations (P = 0.41), or injury severity (P = 0.16), or treatment of osteoporosis (P = 0.56). CONCLUSION These findings suggest that falls rather than seizures per se are the dominant influence in the pathogenesis of fractures in older patients with epilepsy.

Abstract
BACKGROUND/AIMS We prospectively assessed the frequency, type, severity and cause of treatment among the long-term residents of the Kork Epilepsy Centre in the year 2005. METHODS All long-term residents were exclusively referred to the general surgeon practicing on the campus. Patients were divided into 2 groups comprising 285 patients with active epilepsy and 53 controls who either never had epileptic seizures or have remained seizure free for at least 4 years. RESULTS The 1-year incidence of injuries was 54.2% among the active epilepsy group and 36.8% among controls (p = 0.0275). Several admissions due to differing reasons occurred in 16.8% of people with active epilepsy and in 7.5% of the controls (not significant). More than 2 admissions due to various reasons only occurred in patients with active epilepsy (range 3-9). Of all injuries, 41.3% were directly related to seizures. Among patients with active epilepsy, the 3 most frequent injuries were lacerations, bruises and fractures (29.6, 17.0 and 11.7%, respectively). CONCLUSION According to this prospective study, active epilepsy turned out to be a significant risk factor for injuries under homogenous patient and observer conditions.

Safety of Long-Term Video-Electroencephalographic Monitoring for Evaluation of Epilepsy. Noe KH, Drazkowski JF. Mayo Clin Proc 2009;84(6):495–500. OBJECTIVE: To determine the rate of medical complications from long-term video-electroencephalographic (EEG) monitoring for epilepsy. PATIENTS AND METHODS: We reviewed the medical records of 428 consecutive adult patients with epilepsy who were admitted for diagnostic scalp video-EEG monitoring at Mayo Clinic's site in Arizona from January 1, 2005 to December 31, 2006; 149 met inclusion criteria for the study. Seizure number and type as well as timing and the presence of seizure-related adverse outcomes were noted. RESULTS: Of the 149 adult patients included in the study, seizure clusters occurred in 35 (23%); 752 seizures were recorded. The mean time to first seizure was 2 days, with a mean length of stay of 5 days. Among these patients, there was one episode of status epilepticus, three potentially serious electrocardiographic abnormalities, two cases of postictal psychosis, and four vertebral compression fractures during a generalized convulsion, representing 11% of patients with a recorded generalized tonic–clonic seizure. No deaths, transfers to the intensive care unit, falls, dental injuries, or pulmonary complications were recorded. An adverse event requiring intervention or interfering with normal activity occurred in 21% of these patients. Length of stay was not affected by occurrence of adverse events. CONCLUSION: Prolonged video-EEG monitoring is an acceptably safe procedure. Adverse events occur but need not result in substantial morbidity or increase length of hospitalization. Appropriate precautions must be in place to prevent falls and promptly detect and treat seizure clusters, status epilepticus, serious electrocardiographic abnormalities, psychosis, and fractures.

Abstract
Eslicarbazepine is a new dibenzazepine antiepileptic agent. It is a high affinity antagonist of the voltage-gated sodium channel. It is closely related to both carbamazepine and oxcarbazepine. Eslicarbazepine has similar affinity to inactivated sodium channels (channels in just activated neurons) as carbamazepine, and greater efficacy in animal models of seizure than oxcarbazepine. In human placebo-controlled trials of a single daily dose of eslicarbazepine added to other anti-epileptic agents, significant seizure reductions occurred with 800 and 1200 mg daily, with nearly half of the patients experiencing a greater than 50% reduction in seizure frequency. Adverse events (AEs) occurred in over 50% of patients receiving therapeutic doses of eslicarbazepine (compared to 31.4%–44.7% of placebo-treated subjects), but were generally mild or moderate. Eight to 19.6% of eslicarbazepine treated patients discontinued due to AEs (compared to 3.9%–8.5% of placebo-treated subjects). In these patients receiving combination anticonvulsant therapy, the most common AEs were dizziness, nausea and vomiting, somnolence, and diplopia. Eslicarbazepine is an effective and reasonably well-tolerated adjunct in patients with suboptimal control of their partial seizures.

Abstract
Antiepileptic drugs (AEDs) are used increasingly in clinical practice to treat a number of conditions. However, the relationship between the use of these medications, particularly the newer AEDs, and fracture risk has not been well characterized. We used data from the Women's Health Initiative (WHI) to determine the relationship bewteen the use of AEDs and falls, fractures, and bone mineral density (BMD) over an average of 7.7 years of follow-up. We included 138,667 women (1,385 users of AEDs and 137,282 nonusers) aged 50 to 79 years in this longitudinal cohort analyses. After adjustment for covariates, use of AEDs was positively associated with total fractures [hazard ratio (HR) = 1.44, 95% confidence interval (CI) 1.30-1.61], all site-specific fractures including the hip (HR = 1.51, 95% CI 1.05-2.17), clinical vertebral fractures (HR = 1.60, 95% CI 1.20-2.12), lower arm or wrist fractures (HR = 1.40, 95% CI 1.11-1.76), and other clinical fractures (HR = 1.46, 95% CI 1.29-1.65) and two or more falls (HR = 1.62, 95% CI 1.50-1.74) but not with baseline BMD or changes in BMD (p > or = .064 for all sites). Use of more than one and use of enzyme-inducing AEDs were significantly associated with total fractures (HR = 1.55, 95% CI 1.15-2.09 and HR = 1.36, 95% CI 1.09-1.69, respectively). We conclude that in clinical practice, postmenopausal women who use AEDs should be considered at increased risk for fracture, and attention to fall prevention may be particularly important in these women.

Abstract
Although it is known that depressive symptoms have significant impact on quality of life (QOL) in epilepsy and that atypical symptoms are common in interictal depression, less is known about the clinical significance of the atypical form of interictal depression as opposed to major depressive disorder (MDD). We compared quality of life among 30 patients with epilepsy (1) with major depressive disorder (group D), (2) with interictal dysphoric disorder (group ID), and (3) without MDD or IDD (group ND). The mean t scores on the 31-item Quality of Life in Epilepsy questionnaire were lower in groups D (20.3, 95% CI 9.02-31.7, n=3) and ID (38.7, 95% CI 34.2-43.2, n=19) compared with group ND (59.1, 95% CI 52.2-66.1, n=8). These results underscore the clinical significance of IDD that not only accounts for a large portion of mood symptoms in the population with epilepsy, but also is not adequately captured by the DSM-IV criteria for MDD.

Abstract
OBJECTIVE To assess and compare the effect of Pre-existing epilepsy/seizure disorder and drug/alcohol problem on the hazard of repeat traumatic brain injury (TBI) in persons with TBI who participated in a follow-up study. DESIGN Retrospective cohort. SETTING Acute care hospitals in South Carolina. PARTICIPANTS Participants were from the South Carolina Traumatic Brain Injury Follow-up Registry cohort of persons (N=2118) who were discharged from an acute care hospital in South Carolina and who participated in a year-1 follow-up interview. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Repeat TBI was defined by 2 isolated events of TBI in the same person at least 72 hours apart and recorded in hospital discharge or emergency department records from 1999 through 2005. RESULTS A Cox proportional hazards model was used to assess the associations of Pre-existing epilepsy/seizure disorder and drug/alcohol problem with time to repeat TBI, controlling for other confounding factors. There were 2099 persons with information on both Pre-existing conditions. There were 147 (7%) persons who sustained repeat TBI after recruitment to the follow-up study, and 82 (3.9%) had a previous TBI before recruitment for which they were seen in the hospital discharge or emergency department since 1996. The hazard of repeat TBI for persons with Pre-existing epilepsy/seizure disorder was 2.3 times the hazard for those without (hazard ratio, 2.3; 95% confidence interval, 1.2-4.4; P=.011). Pre-existing drug/alcohol problem was not associated with repeat TBI. Other variables significantly associated with repeat TBI were having a prior TBI, being insured under Medicaid, and having no insurance. CONCLUSIONS Pre-existing epilepsy/seizure disorder predisposes to repeat TBI. Appropriate management of seizure control may be an important strategy to allay the occurrence of repeat TBI.

Abstract
Several studies show that the risk of accidents involving patients with epilepsy is much higher compared to the general population. The objective of this study was to identify the frequency and type of seizure related injuries in children diagnosed with epilepsy. In addition we also assessed possible risk factors associated with this seizure related accidents in childhood. This study was conducted at the pediatric epilepsy clinic of Unicamp, from January 2005 to August 2006. We evaluated 100 consecutive children with epilepsy. Parents were interviewed by one of the authors using a structured questionnaire that included questions about seizure related accidents and related injuries. Forty-four patients reported seizure related accidents. Eighteen patients needed medical assistance at an emergency room due the severity of their seizure related accident. Forty patients reported having a seizure related accident prevented by a bystander. Another 14 patients reported avoiding a seizure related accident by luck alone. Contusions and lacerations were the most common type of lesion associated with seizures. Patients with symptomatic/probable symptomatic epilepsy and those using higher numbers of anti-epileptic drugs (AEDs) were at greater risk for seizure related accidents (p<0.05). We conclude that patients with symptomatic/probable symptomatic epilepsy and on multiple AEDs are at increased risk of seizure related accidents. Parents and caretakers should be even more cautious about risk of injury in such patients.

Abstract
The objective of this retrospective claims database study was to compare the costs of care from a U.S. payer perspective before and after epilepsy treatment in emergent care settings and, secondarily, to describe the frequency of toxic effects and physical injuries occurring on the date of the emergent care. Nine and four-tenths percent of patients receiving emergent care for epilepsy (114/1213) had an injury or adverse antiepileptic drug effect on the same date. The majority of incidents were superficial injuries and contusions (28%), fractures (21%), open wounds or injury to blood vessels (19%), intracranial injury (10%), and/or medication toxicity (10%). Both non-epilepsy-related (US$12,745.56) and epilepsy-related (US$2013.62) direct medical costs of care pre-index were significantly different from those post-index (US$15,274.95 and US$7087.53, respectively). The cost of care for possible reestablishment of epilepsy control and treatment of co-occurring injuries is significant when compared with that for the period prior to seizure.

Abstract
Women with epilepsy face additional challenges when compared to their peers. Hormonal influences may increase seizure activity, alter endocrine function, and affect fertility. In this population, antiepileptic drugs (AEDs) reduce the efficacy of contraception methods and increase the risk of fetal malformations. Other pertinent issues to women with epilepsy include breastfeeding as well as bone mineral health. This article summarizes our current, collective knowledge of these issues and makes specific recommendations with respect to management.

Abstract
BACKGROUND The proper clinical context to initiate or discontinue antiepileptic drug (AED) treatment has been extensively studied over the past 40 years. Differences in study design and methodology have led to reports of seizure recurrence rates of 7% to 96% in drug initiation trials and seizure relapse rates of 12% to 67% in drug withdrawal trials. A number of different historical and clinical factors have been cited in various studies as altering seizure risk. Our objective was to review the data from large, well-conducted, prospective studies. REVIEW SUMMARY We performed an electronic search of 3 medical and scientific databases for articles on initiating or withdrawing antiepileptic medication. Our review focused primarily on articles meeting specific inclusion and exclusion criteria. We discuss the risk of seizure recurrence after a first seizure and the factors associated with an elevated risk of recurrence. The risks of treatment, including life-threatening idiosyncratic reactions and dose-related physical and cognitive side effects are reviewed. We also summarize the data on the seizure relapse risk after drug discontinuation and the factors associated with an increased relapse risk. Benefits of successful AED withdrawal are highlighted. The special considerations of treatment initiation and withdrawal in the pediatric population are explored. We propose general guidelines to assist the clinician in evaluating the risk/benefit ratio of initiating and withdrawing antiepileptic drugs. CONCLUSION Drug initiation after a first seizure decreases early seizure recurrence, but does not affect the long-term prognosis of developing epilepsy. Medication withdrawal after a period of seizure remission increases the risk of relapse, but the benefits of successful AED discontinuation may be substantial. In the end, the decision of whether to initiate treatment after a single seizure and whether to withdraw AED therapy in patients enjoying a prolonged period of seizure freedom should be made on an individual case basis, which balances the risk of seizure relapse and subsequent disability against the likely impact of medication-related physical, cognitive, and psychologic adverse effects.

Abstract
OBJECTIVE To determine the rate of medical complications from long-term video-electroencephalographic (EEG) monitoring for epilepsy. PATIENTS AND METHODS We reviewed the medical records of 428 consecutive adult patients with epilepsy who were admitted for diagnostic scalp video-EEG monitoring at Mayo Clinic's site in Arizona from January 1, 2005, to December 31, 2006; 149 met inclusion criteria for the study. Seizure number and type as well as timing and presence of seizure-related adverse outcomes were noted. RESULTS Of the 149 adult patients included in the study, seizure clusters occurred in 35 (23%); 752 seizures were recorded. The mean time to first seizure was 2 days, with a mean length of stay of 5 days. Among these patients, there was 1 episode of status epilepticus, 3 potentially serious electrocardiographic abnormalities, 2 cases of postictal psychosis, and 4 vertebral compression fractures during a generalized convulsion, representing 11% of patients with a recorded generalized tonic-clonic seizure. No deaths, transfers to the intensive care unit, falls, dental injuries, or pulmonary complications were recorded. An adverse event requiring intervention or interfering with normal activity occurred in 21% of these patients. Length of stay was not affected by occurrence of adverse events. CONCLUSION Prolonged video-EEG monitoring is an acceptably safe procedure. Adverse events occur but need not result in substantial morbidity or increase length of hospitalization. Appropriate precautions must be in place to prevent falls and promptly detect and treat seizure clusters, status epilepticus, serious electrocardiographic abnormalities, psychosis, and fractures.

Abstract
Epilepsy during adolescence can impede the development of psychosocial independence and typical biological maturational processes. We examined in parallel the experiences and perceptions of adolescent patients with epilepsy and their caregivers. Specifically, we focused on frequency and type of seizures, comorbid conditions, adherence to therapies, productivity, clinical and quality of life consequences of seizures, estimated use and content of seizure emergency plans, and the patient-physician relationship. Two cross-sectional online surveys were conducted among 153 adolescent patients with epilepsy and their respective caregivers. A total of 35% of adolescents indicated that they had been nonadherent to antiepileptic medications in the prior month. Adolescents scored significantly lower compared with their peers on quality-of-life measures. Adolescents and caregivers reported similarly on nearly all domains. An adolescent-centered epilepsy management program may help alleviate concerns and also help the adolescent independently manage their epilepsy as they transition into adulthood.

Abstract
INTRODUCTION Physical activity in sports comes with an inherent risk for injury. For children with disabilities, their injury risk may be complicated by preexisting disability. However, very little research exists on sports injuries to young athletes with disabilities. To best manage potential injuries to children with disabilities, data on sports injury patterns are needed. The purpose of this study was to measure the frequency of and risk factors for injury to high school athletes with disabilities. METHODS A total of 210 athletes from 8 special education high schools that are part of an interscholastic sports league participated in the study. Seven of the 8 schools were followed for 1 season each of basketball, softball, soccer, and field hockey, and 1 school enrolled only during field hockey. Data were collected from coaches on daily exposure sessions (game, practice, and conditioning, as well as length of session), athlete characteristics (disability, gender, age, seizure history, and behavioral problems), and nature of injuries resulting in any type of medical treatment. RESULTS Thirty-eight injuries were reported among 512 special athletes for a rate of 2.0 per 1000 athlete exposures. Soccer (3.7 per 1000) had the highest rate of injury. More than half of the injuries were abrasions and contusions. Those at highest risk for injury were athletes with autism, athletes with histories of seizures, and starters. Athletes with autism had approximately 5 times the injury rate of athletes with mental disabilities. Athletes with seizures had >2.5 times the rate of injury reported among those with no seizure history. CONCLUSIONS This adapted sports program is a reasonably safe activity for children with disabilities. Nonetheless, findings have important implications for prevention. The preparticipation medical examination may be an excellent opportunity to create special guidelines, particularly for athletes with autism and seizure history.

Abstract
PURPOSE The purpose of this descriptive study was to assess whether the Humpty Dumpty Falls Scale (HDFS) identifies hospitalized pediatric patients at high risk for falls. DESIGN AND METHODS The study was a matched case-control design. A chart review of 153 pediatric cases who fell and 153 controls who did not fall were pair-matched by age, gender, and diagnosis. RESULTS High-risk patients fell almost twice as often as low-risk patients (odds ratio 1.87, confidence interval = 1.01, 3.53, p = .03). PRACTICE IMPLICATIONS A Falls Prevention Pediatric Program with the HDFS tool addresses the Joint Commission Patient Safety Goals, but further research is needed to examine HDFS sensitivity-specificity.

Abstract
Non-adherence to epilepsy medications can interfere with treatment and may adversely affect clinical outcomes, although few studies have examined this relationship. This study assessed barriers and drivers to adherence, its impact on quality of life, and the importance of the patient-physician relationship to adherence. Two cross-sectional online surveys were conducted among 408 adult patients with epilepsy and 175 neurologists who treat epilepsy patients. Twenty-nine percent of patients self-reported being non-adherent to antiepileptic medications in the prior month. Non-adherence was found to be associated with reduced seizure control, lowered quality of life, decreased productivity, seizure-related job loss, and seizure-related motor vehicle accidents. Patient-oriented epilepsy treatment programs and clear communication strategies to promote self-management and patients' understanding of epilepsy are essential to maximizing treatment and quality of life outcomes while also minimizing economic costs.

Abstract
OBJECTIVE: To compare the risk of accidents in patients with uncontrolled seizures, in seizure-free patients, and in patients with chronic headache. METHOD: This was a prospective longitudinal case-controlled study with interviews. A semi-structured questionnaire was used in the epilepsy and headache outpatient clinics of the Hospital das Clínicas of UNICAMP. RESULTS: Group I was composed of 48 patients with uncontrolled seizures, group II was composed of 24 seizure-free patients and group III was composed of 32 patients with headache. Thirty-nine patients (81%) in group I, 13 (54%) in group II, and 19 (59%) in group III reported accidents in the last two years. In the first group, 649 accidents (89%) were related to epileptic seizures and the average number of accidents not related to seizures was 1.7. The average number of accidents in groups II and III were both 2.4. CONCLUSION: Epileptic seizure was the most important factor determining the occurrence of accidents in people with epilepsy.
