Abstract
AIMS Attention-deficit hyperactivity disorder (ADHD) is a frequent comorbidity in pediatric epilepsy. Although sleep problems are commonly reported in both children with primary ADHD and epilepsy, those with epilepsy-ADHD comorbidity have not been well studied. This study aimed to compare sleep problems among three groups of children: 1) children with epilepsy, 2) children with epilepsy and ADHD (epilepsy-ADHD), and 3) children with primary ADHD. METHODS 53 children with epilepsy, 35 children with epilepsy-ADHD, and 52 children with primary ADHD completed the Children's Sleep Habits Questionnaire (CSHQ). Neurology clinic charts were reviewed for the epilepsy-related variables. ADHD subtypes were diagnosed according to the DSM-IV. RESULTS Children with epilepsy-ADHD had the highest CSHQ total scores, while children with primary ADHD had higher scores than those with epilepsy. Besides the total score, epilepsy-ADHD group differed from the primary ADHD and epilepsy groups with higher CSHQ subscores on sleep onset delay and sleep anxiety. The frequency of moderate-severe sleep problems (CSHQ>56) was 62.9% in children with epilepsy-ADHD, while it was 40.4% and 26.4% in children with primary ADHD and epilepsy, respectively. CSHQ total scores were not different between ADHD subtypes in both children with epilepsy-ADHD and those with primary ADHD. None of the epilepsy-related variables were found to be associated with CSHQ scores. DISCUSSION Epilepsy-ADHD is associated with a significantly poor sleep quality which is beyond that of primary ADHD and epilepsy.

Comparing sleep profiles between patients with juvenile myoclonic epilepsy and symptomatic partial epilepsy: Sleep questionnaire-based study. Epilepsy Behav 2017; 66:34-38. [PMID: 28012415 DOI: 10.1016/j.yebeh.2016.10.009] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2016] [Revised: 09/16/2016] [Accepted: 10/09/2016] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Patients with epilepsy commonly report excessive daytime sleepiness and daytime fatigue, which may be attributed to the direct effect of seizures, a side effect of antiepileptic drugs or a combination of the two. The aim of the study was to compare sleep profiles in patients with juvenile myoclonic epilepsy (JME) and symptomatic partial epilepsy (PE) in drug naïve and treated patients using standardized sleep questionnaires. METHODS Three study groups: - 1) juvenile myoclonic epilepsy (N=40) [drug naïve (N=20); On sodium valproate (SVA) (N=20)]; 2) symptomatic partial epilepsy (N=40) [drug naïve (N=20); On carbamazepine (CBZ) (N=20)]; 3) healthy controls (N=40) completed 3 standardized sleep questionnaires - Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and NIMHANS Comprehensive Sleep Disorders Questionnaire. Scores were compared using t-test and Chi-squared tests (P≤0.005). RESULTS The mean PSQI scores as well as the proportion of subjects with abnormal PSQI scores were higher in patients with JME and PE compared to controls. Although the mean ESS scores were comparable between patients with epilepsy and controls, the percentage of patients with partial epilepsy having abnormal ESS scores was higher. No significant differences were present between drug naïve and treatment monotherapy groups. Excessive daytime somnolence was reported more often by patients with JME compared to patients with partial epilepsy and controls. CONCLUSION This study found that patients with epilepsy have a higher prevalence of poor sleep quality compared to controls. Moreover, a significantly higher percentage of patients with partial epilepsy had higher ESS scores compared to healthy controls. However, there was no difference between ESS and PSQI scores between drug naïve and treated patients with JME or PE. SIGNIFICANCE Poor sleep quality is more prevalent in patients with epilepsy irrespective of the use of antiepileptic medications. Excessive daytime somnolence is more commonly seen in patients with partial epilepsy when compared to the general population.

Abstract
AIM The aim of this study was to analyze the prevalence of sleep disorders among patients with epilepsy and to compare the incidence of sleep disorders between the clinical and demographics factors. MATERIALS AND METHODS The study was conducted among 302 patients with epilepsy. Sleep disturbances were measured with the Polish version of the Pittsburgh Sleep Quality Questionnaire (PSQI). The questionnaire prepared and applied by the authors contained questions relating to sociodemographic characteristics, clinical status, and sleep. RESULTS AND CONCLUSION Mean PSQI score in the study group was 9±2 points, with the range of 4-16 points. PSQI test results were analyzed with regard to clinical and demographic characteristics of those suffering from epilepsy: gender, age, profession, body mass index, illness duration, number of medicines taken, type of seizures, frequency of seizures, time which elapsed since last seizure, provocative factor of seizure attacks, occurrence of adverse effects of antiepileptic drugs (AEDs). Furthermore, the existence of a relationship between PSQI test result and particular sleep-related factors or particular sleep conditions was examined. However, the examination of a relationship between certain independent variables and the final PSQI test result did not prove the existence of a statistically relevant influence (in all cases P>0.05).

Abstract
PURPOSE The relationship between sleep and seizures is intricate. The aim of this study was to assess whether sleep loss is an independent seizure precipitant in a clinical setting. METHODS In this prospective, observational cross-over study, 179 consecutive hospital admissions for epileptic seizures were included. A semi-structured interview regarding several seizure precipitants was performed. The sleep pattern prior to the seizure, as well as alcohol, caffeine and drug use, were recorded. The interview was repeated by telephone covering the same weekday at a time when there had been no recent seizure. The Hospital Anxiety and Depression Scale (HADS) and a visual analogue scale for perceived stress were applied at admission. Student's t-test, Fisher exact test and ANOVA were used for statistical analyses. RESULTS Complete data for analysis were retrieved in 144 patients. The sleep-time during the 24h prior to the seizure was lower (7.3h) compared to follow-up (8.3h; p<0.0005). Caffeine consumption and use of relevant non antiepileptic drugs (AED) were not different. HADS and stress scores at admission did not correlate with sleep-time difference. In ANOVA, controlled for alcohol consumption and AED use, the sleep-time difference remained significant (p=0.008). The interaction with alcohol intake was high, but the sleep-time difference remained highly significant also for the non- and low-consumption (≤2 units per day) subgroup (n=121, 7.50h vs 8.42h, p=0.001). CONCLUSION Epileptic seizures are often precipitated by a combination of various clinical factors, but sleep loss stands out as an independent seizure trigger.

Abstract
BACKGROUND AND OBJECTIVE Children with epilepsy are at increased risk of other disorders and difficulties, preceding, cooccurring with, or after the diagnosis of epilepsy. Risk estimates vary, few studies are population-based, and few provide comprehensive assessments of comorbidities. We used nationwide registry data to describe frequencies of medical, neurologic, developmental, and psychiatric conditions occurring before and after children are diagnosed with childhood epilepsy. METHODS Data were obtained from the Norwegian Patient Registry, which is an administrative database recording International Classification of Diseases, 10th Revision diagnoses from all government-funded specialist health services in Norway (outpatient consultations and hospitalizations). We included data from the years 2008 through 2013 for all children born in Norway between 1996 and 2013 (0-17 years of age at the end of follow-up). Children with epilepsy were compared with the general child population, adjusting for sex and age. We also compared children with complicated epilepsies (ie, epilepsies with additional neurologic and/or developmental disorders) to children with uncomplicated epilepsies. RESULTS The study population included 1 125 161 children. There were 6635 (0.6%) children with epilepsy. Nearly 80% of children with epilepsy had ≥1 comorbid disorder. All types of disorders were more frequent in children with epilepsy, with additional medical disorders recorded in 55%, neurologic disorders in 41%, and developmental/psychiatric disorders in 43%. Children with complicated epilepsies had the highest overall levels of comorbidity, but the risk of medical and psychiatric comorbidities was also substantial among children with uncomplicated epilepsies. CONCLUSIONS The overall frequency of comorbid disease is high in children with epilepsy, including children with presumably uncomplicated epilepsies.

Abstract
BACKGROUND Epilepsy is the most common chronic neurological disease in the United States, and 70% of diagnoses occur in late adolescence or adulthood. A disease of the brain, epilepsy can affect sleep. Lack of adequate or high-quality sleep can cause decrements in quality of life. Adults living with epilepsy are at especially high risk for sleep alterations, and these changes in sleep can worsen their epilepsy. The purpose of the study was to describe the perceived effect of epilepsy on sleep in adults who developed epilepsy in late adolescence or adulthood. Research questions included (a) "In adults with epilepsy, what is the perceived change in ability to sleep well because of having epilepsy?"; (b) "In adults with epilepsy, is there a significant relationship between perceived changes in ability to sleep well and perceived changes in overall life because of having epilepsy?"; and (c) "In adults with epilepsy, is there a significant relationship between perceived changes in ability to sleep well because of having epilepsy and total Life Changes in Epilepsy Scale (LCES) scores?". METHODS One hundred seventy-four adults with epilepsy were recruited. Utilizing data collected via the LCES, a quantitative descriptive/correlational design was utilized. Analyses were carried out to answer each research question. RESULTS The mean score for the sleep item of the LCES was 2.76 (SD = 1.31), indicating an overall negative change in ability to sleep well. There was a statistically significant, strong positive relationship between the sleep and overall life changes items of the LCES (Pearson r = .476, p < .0000) and also between the sleep item and total LCES scores (Pearson r = .620, p < .0000). IMPLICATIONS Findings from this study contribute to the extant literature by revealing epilepsy-related changes in sleep as perceived by adults living with epilepsy specifically because of having epilepsy. On the basis of findings rendered from this sample, having epilepsy can lead to perceived negative changes in a person's ability to sleep well, and these negative changes are significantly correlated with negative overall life changes. Recommendations for clinical practice and research can be made based on current results.

Abstract
Rett syndrome is a rare but severe neurological disorder associated with a mutation in the methyl CpG binding protein 2 (MECP2) gene. Sleep problems and epilepsy are two of many comorbidities associated with this disorder. This study investigated the prevalence and determinants of sleep problems in Rett syndrome using an international sample. Families with a child with a confirmed Rett syndrome diagnosis and a MECP2 mutation registered in the International Rett Syndrome Phenotype Database (InterRett) were invited to participate. Questionnaires were returned by 364/461 (78.9%) either in web-based or paper format. Families completed the Sleep Disturbance Scale for Children and provided information on the presence, nature, and frequency of their child's sleep problems. Multivariate multinomial regression was used to investigate the relationships between selected sleep problems, age group, and genotype and linear regression for the relationships between sleep disturbance scales and a range of covariates. Night waking was the most prevalent sleep problem affecting over 80% with nearly half (48.3%) currently waking often at night. Initiating and maintaining sleep was most disturbed for younger children and those with a p.Arg294* mutation. Severe seizure activity was associated with poor sleep after adjusting for age group, mutation type, and mobility. We were surprised to find associations between the p.Arg294* mutation and some sleep disturbances given that other aspects of its phenotype are milder. These findings highlight the complexities of aberrant MECP2 function in Rett syndrome and explain some of the variation in manifestation of sleep disturbances. © 2016 Wiley Periodicals, Inc.

Abstract
The cerebellum assists coordination of somatomotor, respiratory, and autonomic actions. Purkinje cell alterations or loss appear in sudden infant death and sudden death in epilepsy victims, possibly contributing to the fatal event. We evaluated breathing patterns in 12 wild-type (WT) and Lurcher mutant mice with 100% developmental cerebellar Purkinje cell loss under baseline (room air), and recovery from hypercapnia, a concern in sudden death events. Six mutant and six WT mice were exposed to 4-min blocks of increasing CO2 (2, 4, 6, and 8%), separated by 4-min recovery intervals in room air. Breath-by-breath patterns, including depth of breathing and end-expiratory pause (EEP) durations during recovery, were recorded. No baseline genotypic differences emerged. However, during recovery, EEP durations significantly lengthened in mutants, compared to WT mice, following the relatively low levels of CO2 exposure. Additionally, mutant mice exhibited signs of post-sigh disordered breathing during recovery following each exposure. Developmental cerebellar Purkinje cell loss significantly affects compensatory breathing patterns following mild CO2 exposure, possibly by inhibiting recovery from elevated CO2. These data implicate cerebellar Purkinje cells in the ability to recover from hypercarbia, suggesting that neuropathologic changes or loss of these cells contribute to inadequate ventilatory recovery to increased environmental CO2. Multiple disorders, including sudden infant death syndrome (SIDS) and sudden unexpected death in epilepsy (SUDEP), appear to involve both cardiorespiratory failure and loss or injury to cerebellar Purkinje cells; the findings support the concept that such neuropathology may precede and exert a prominent role in these fatal events.

Abstract
PURPOSE The purpose of this study was to document the frequency of sleep problems including poor sleep quality, excessive daytime sleepiness, and insomnia in subjects with epilepsy compared with healthy controls and to determine the factors associated with these sleep disturbances. METHODS We recruited 180 patients with epilepsy (age: 43.2 ± 15.6 years, men: 50.0%) and 2836 healthy subjects (age: 44.5 ± 15.0 years, men: 49.8%). Sleep and the anxiety/mood profiles were measured using the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Insomnia Severity Index, Goldberg Anxiety Scale, and Patient Health Questionnaire-9 depression scale. Associations of sleep problems with epilepsy and other factors were tested by multiple logistic regression analysis, adjusted for age, gender, body mass index, alcohol intake, smoking, perceived sleep insufficiency, and habitual snoring. RESULTS Sleep disturbances were more common in the group with epilepsy than in the controls (53.3% vs. 25.5%; p<0.001). Poor sleep quality, excessive daytime sleepiness, and insomnia were significantly associated with epilepsy (odds ratio [95% confidence interval]: 3.52 [2.45-5.05], 2.10 [1.41-3.12], 5.91 [3.43-10.16], respectively). Depressive mood, anxiety, and perceived sleep insufficiency contributed to the presence of sleep disturbances. In the group with epilepsy, seizure remission for the past year related to a lower frequency of insomnia, whereas age, sex, type of epilepsy, and number of antiepileptic drugs were not correlated with sleep problems. CONCLUSION Epilepsy was significantly associated with the higher frequency of sleep disturbances, which supports the importance of screening sleep problems in patients with epilepsy and providing available intervention.

Abstract
A growing body of research reveals strong relationships between sleep disturbance, sleep architecture, and neuropsychological functioning in children. Children with epilepsy experience numerous neuropsychological comorbidities, including cognitive deficiencies and emotional/behavioral difficulties; thus, it is reasonable to consider the moderating role of sleep in this population. This review summarizes findings involving the prevalence and characteristics of sleep problems often experienced by children with epilepsy. The complex and bidirectional relationship between sleep and seizure frequency is discussed. Research pertaining to the relationship between sleep disturbance and daytime cognition as well as behavior reveals a substantial association between these variables. Clinically relevant practices related to the assessment and treatment of sleep-related complications are reviewed, and directions for further research involving intervention and assessment are also reviewed.

Abstract
PURPOSE For patients with uncontrolled epilepsy, the severity and postictal sequelae of seizures might be more impactful than their frequency. Seizure severity is often assessed using patient-reported outcome (PRO) instruments; however, evidence of content validity for existing instruments is lacking. Our aim was to understand the real-life experiences of patients with uncontrolled epilepsy. METHODS A preliminary conceptual model was developed. The model was refined through (1) a targeted literature review of qualitative research on seizure severity; (2) interviews with four clinical epilepsy experts to evaluate identified concepts; and (3) qualitative interviews with patients with uncontrolled epilepsy, gathering descriptions of symptoms and impacts of epilepsy, focusing on how patients experience and describe "seizure severity." Findings were summarized in a final conceptual model of seizure severity in epilepsy. RESULTS Twenty-five patients (12 who experienced primary generalized tonic-clonic seizures and 13 who experienced partial-onset seizures) expressed 42 different symptoms and 26 different impacts related to seizures. The final conceptual model contained a wide range of concepts related to seizure frequency, symptoms, and duration. CONCLUSION Our model identified several new concepts that characterize the patient experience of seizure severity. A seizure severity PRO instrument should cover a wide range of seizure symptoms alongside frequency and duration of seizures. This qualitative work reinforces the notion that measuring seizure frequency is insufficient and that seizure severity is important in defining the patient's experience of epilepsy. This model could be used to assess the content validity of existing PRO instruments, or could support the development of a new one.

Abstract
Sleep-wake cycle disturbances are prevalent in patients with medical conditions and frequently present as part of a symptom cluster. Sleep disturbances impair functioning and quality of life, decrease adherence to treatments of the primary medical condition, and increase morbidity and mortality. The pathophysiology of sleep disturbances in these patients involves alterations in immune and neuroendocrine function and shares common pathophysiologic pathways with comorbidities such as fatigue and depression. Emphasis is placed on the evaluation and management of medical and psychiatric comorbidities and other factors contributing to sleep problems. Primary treatments include cognitive-behavioral therapy and pharmacotherapy.

Abstract
Epilepsy in children is occasionally associated with variable comorbidities although the frequency of such comorbidity is often difficult to determine. They can be divided into three categories: neurological, psychological, and physical comorbidities. The goal of the present review is to discuss the reported comorbidities of epilepsy in children. The possible mechanisms and associated risk factors-including the effect of seizure frequency and seizure control, types of epilepsy, age of seizure onset, duration of illness, and the possible detrimental effect of antiepileptic drugs-will be described.

Abstract
Dravet Syndrome (DS) is caused by heterozygous loss-of-function mutations in voltage-gated sodium channel NaV1.1. Our mouse genetic model of DS recapitulates its severe seizures and premature death. Sleep disturbance is common in DS, but its mechanism is unknown. Electroencephalographic studies revealed abnormal sleep in DS mice, including reduced delta wave power, reduced sleep spindles, increased brief wakes, and numerous interictal spikes in Non-Rapid-Eye-Movement sleep. Theta power was reduced in Rapid-Eye-Movement sleep. Mice with NaV1.1 deleted specifically in forebrain interneurons exhibited similar sleep pathology to DS mice, but without changes in circadian rhythm. Sleep architecture depends on oscillatory activity in the thalamocortical network generated by excitatory neurons in the ventrobasal nucleus (VBN) of the thalamus and inhibitory GABAergic neurons in the reticular nucleus of the thalamus (RNT). Whole-cell NaV current was reduced in GABAergic RNT neurons but not in VBN neurons. Rebound firing of action potentials following hyperpolarization, the signature firing pattern of RNT neurons during sleep, was also reduced. These results demonstrate imbalance of excitatory vs. inhibitory neurons in this circuit. As predicted from this functional impairment, we found substantial deficit in homeostatic rebound of slow wave activity following sleep deprivation. Although sleep disorders in epilepsies have been attributed to anti-epileptic drugs, our results show that sleep disorder in DS mice arises from loss of NaV1.1 channels in forebrain GABAergic interneurons without drug treatment. Impairment of NaV currents and excitability of GABAergic RNT neurons are correlated with impaired sleep quality and homeostasis in these mice.

Abstract
Comorbidities are common in epilepsy, and their role in quality of life (QOL) is receiving increasing scrutiny. Considerable attention has been focused on the role of depression, the most common comorbidity, with rather less attention paid to its frequent concomitant, anxiety, and other conditions known to be at increased prevalence among people with epilepsy (PWE) when compared to the general population. In this paper, we report findings from a UK-based survey in which we examined self-reporting of two common comorbidities, anxiety and sleep problems, factors associated with them, and their role in QOL in people with and without epilepsy. Data were obtained via mailed questionnaires, supplemented by an internet survey, from PWE and age- and gender-matched controls. Based on self-reported symptoms, PWE were at higher risk of anxiety and sleep problems. Contributory factors for anxiety included poorer general health, worry about seizures, and self-reported antiepileptic drug (AED) side effects. Good social support emerged as protective for anxiety in PWE. Nighttime sleep problems were very common even in controls but were further elevated in PWE. Antiepileptic drug adverse events emerged as an important contributory factor for sleep problems. Trait anxiety emerged as significant for defining overall QOL, and its importance over state anxiety supports the notion of anxiety in PWE as a primarily premorbid condition. In contrast, sleep quality was not consistently predictive of QOL. Our study has important implications for clinical management, emphasizing the need for a holistic approach to address wider patient-reported problems as well as any epilepsy-specific ones.

Abstract
AIMS To observe prevalence of sleep disturbance (SD) in cerebral palsy (CP) children in a specific age-group and its correlation with SD in primary caregivers and other associated factors. MATERIALS AND METHODS This was a prospective cross-sectional study. SD assessed using Sleep Disturbance Scale for Children (SDSC) in CP children and Pittsburgh Sleep Quality Index (PSQI) in caregivers. Fifty cases of clinically diagnosed CP [27 females, mean age: 107.9 29.5 months (range: 78-180 months)] fulfilling criteria were included. RESULTS Eighteen (36%) children had pathological sleep total score (TS) and Disorders of Initiating and Maintaining Sleep (DIMS) was the commonest SD (n = 25, 50%). All primary caregivers were mothers. Twenty-five (50%) mothers had SD on PSQI scale. DIMS, Disorders of Excessive Somnolence (DES), and TS had significant correlation with PSQI (P < 0.05). Disorders of Arousal (DA) and TS had significant correlation with seizures (P < 0.05) in CP children. Bed-sharing had significant correlation with SD in caregivers (P < 0.001) but not with CP children. No significant correlation was observed between SD in CP and gross motor function (Gross Motor Function Classification System), use of orthoses, and dental caries. INTERPRETATION Children with CP have underreported significant SD, which negatively impacts caregiver's sleep also. Seizure disorders and medications contribute significantly to SD.

Abstract
Data on the relationship between sleep disturbances and refractory epileptic encephalopathies (EEs) are scarce. Our aim was to assess, by means of nocturnal polysomnography, if children with EEs present with objective alterations in sleep organization. Twenty-three children with EEs (12 males; mean age: 8.7±1.4years) and 40 healthy controls (22 males; mean age: 8.8±1.1years) underwent an overnight full polysomnography (PSG). Relative to controls, children with EEs showed a significant reduction in all PSG parameters related to sleep duration time in bed (TIB-min p<0.001), total sleep time (TST-min p<0.001), and sleep percentage (SPT-min p<0.001), as well as significantly higher REM latency (FRL-min p<0.001), rate in stage shifting (p=0.005), and number of awakenings/hour (p=0.002). Relative to controls, children with EEs also showed significant differences in respiratory parameters (AHI/h p<0.001, ODI/h p<0.001, SpO2% p<0.001, SpO2 nadir% p<0.001) and a higher rate of periodic limb movements (PLMs% p<0.001). Our findings suggest that sleep evaluation could be considered mandatory in children with refractory epileptic encephalopathy in order to improve the clinical management and the therapeutic strategies.

Abstract
Despite the profound reduction in conscious awareness associated with sleep, sensory cortex remains highly active during the different sleep stages, exhibiting complex interactions between different cortical sites. The potential functional significance of such spatial patterns and how they change between different sleep stages is presently unknown. In this electrocorticography study of human patients, we examined this question by studying spatial patterns of activity (broadband gamma power) that emerge during sleep (sleep patterns) and comparing them to the functional organization of sensory cortex that is activated by naturalistic stimuli during the awake state. Our results show a high correlation (p < 10(-4), permutation test) between the sleep spatial patterns and the functional organization found during wakefulness. Examining how the sleep patterns changed through the night highlighted a stage-specific difference, whereby the repertoire of such patterns was significantly larger during rapid eye movement (REM) sleep compared with non-REM stages. These results reveal that intricate spatial patterns of sensory functional organization emerge in a stage-specific manner during sleep.

Abstract
Background. Sleep complaints are common in patients with epilepsy (PWE). Excessive daytime sleepiness (EDS) is one of the most reported complaints and its impact is still a matter of debate. Objective. Evaluate the relationship between EDS and epilepsy, with emphasis on prevalence, assessment, and causes. Methods. A systematic review on PubMed database in the last 10 years (2002 to 2012). The search returned 53 articles and 34 were considered relevant. After citation analysis, 3 more articles were included. Results. Most studies were cross-sectional and questionnaire based. 14 papers addressed EDS as the primary endpoint. 14 adult and 3 children studies used subjective and objective analysis as methodology. The number of studies increased throughout the decade, with 21 in the last 5 years. Adult studies represent almost three times the number of children studies. EDS prevalence in PWE varies from 10 to 47.5%. Prevalence was higher in developing countries. Conclusion. EDS seems to be related more frequently to undiagnosed sleep disorders than to epilepsy-related factors, and although it affects the quality of life of PWE, it can be improved by treating comorbid primary sleep disorders.

Abstract
PURPOSE The purposes of this study were to explore the prevalence of sleep disturbances in a large cohort of school-aged children with partial epilepsy, to compare the findings with those in children without epilepsy of the same age and gender, and to evaluate the relationship between sleep disturbances and health-related quality of life (HRQoL). METHODS One hundred thirty children with partial epilepsy aged 4 to 10years, who were treated in the outpatient setting of a Dutch epilepsy clinic, and 161 age- and sex-matched controls participated in this study. In addition to providing information about their child's demography and health, parents of both groups of children completed three questionnaires to measure their child's sleep [Sleep Disturbance Scale for Children (SDSC), Medical Outcomes Study-Sleep Scale (MOSS-S), and Groningen Sleep Quality Scale (GSQS)] and one questionnaire to measure quality of life (Kidscreen-27). Parents of children with epilepsy also completed the Hague Scales to measure the severity of epilepsy. The prevalence of sleep disturbances and scores on HRQoL in children with and without epilepsy were compared. Additionally, the HRQoL scores were compared between children with and without sleep disturbances in children both with and without epilepsy. RESULTS The answers for all three questionnaires suggested worse sleep in children with epilepsy than in children of the same age and gender without epilepsy. Pathological scores (T-value>70) for total SDSC were seen twelve times more frequently in children with epilepsy (36.92% vs. 3.01%, p<0.001). Children with epilepsy also scored significantly lower for all dimensions of HRQoL. Between subgroups of children with and without disturbed sleep, insignificant differences in quality of life were found, with the lowest scores in children with sleep disturbances in both groups. CONCLUSION This study confirms the high prevalence of disturbed sleep, as well as its effect on quality of life, in a large group of children with partial epilepsy. The abnormalities are both more prevalent and more severe than in children without epilepsy.

Abstract
A reciprocal relationship exists between sleep and epilepsy. The quality of sleep is affected by the presence and frequency of seizures, type of antiepileptic therapy utilized, and coexisting primary sleep disorders. Daytime somnolence is one of the most common adverse effects of antiepileptic therapy, with specific pharmacologic agents exhibiting a unique influence on components of sleep architecture. The newer generation of antiseizure drugs demonstrates improved sleep efficiency, greater stabilization of sleep architecture, prolongation of REM sleep duration, and increased quality of life measures. The emerging field of chronoepileptology explores the relationship between seizures and circadian rhythms, aiming for targeted use of antiseizure therapies to maximize therapeutic effects and minimize the adverse events experienced by the patients.

Abstract
Background: On the basis of clinical experience, it seems that sleep disturbances are common in children with cerebral palsy (CP); however, there is a lack of research and objective data to support this observation. Aim of Work: Our aim was to assess sleep of children with cerebral palsy, using validated sleep questionnaire. Subjects and Methods: one hundred children with diagnosis of CP were investigated via sleep questionnaires, with their ages from 2-12 years. The 100 children with CP were divided into two groups, pre-school group (52 children had a mean age 2.35 ± 1.04 years) and school ages group (48 children had a mean age 10.21 ± 3.75 years). Results: We found high incidence of sleep problem in both pre-school and school age groups. We found that pre-school children have more prevalence of early insomnia (46.2%, P value 0.028) and sleep bruxism (50%, P value 0.000), while school group suffer more sleep disordered breathing (SDB) (50%, P value 0.001), more nightmares (50%, P value 0.001), more sleep talking (12.5% P value 0.049), and more excessive daytime sleepiness (EDS) (62.5%, P value 0.001). Conclusion: Results of our study indicate that CP children have high incidence of sleep problem in both pre-school and school age groups.

Abstract
PURPOSE To evaluate morning dream recall frequency and content in patients with temporal lobe epilepsy (TLE). METHODS Fifty-two patients with pharmacoresistant TLE submitted to a written dream diary during five consecutive days and continuous video-electroencephalographic (video-EEG) monitoring. A matched control group of 41 healthy subjects completed the same diary at home. The number of recalled dreams (including long dreams) and nonrecalled dream mentation were collected, and the Dream Recall Rate (DRR) was calculated. Hall and Van de Castle dream content analysis was performed. KEY FINDINGS Greater than 70% of patients with TLE (37 of 52) recall their dreams, but DRR rate in these patients is lower than in controls (p ≤ 0.001). Dream recall does not appear to be influenced by the presence of neuropsychological deficits nor seizure frequency. In dreams descriptions, TLE patients (vs. controls) have a higher percentage of familiarity in settings and fewer dreams with at least one success. SIGNIFICANCE Onirical activity of patients with TLE is different from that of healthy subjects. Our results support the role of mesial and neocortical temporal structures in dream experience. The selective activation of dysfunctional mesial structures may be responsible for some of the observed variability. However, dream content changes can also mirror social and psychological comorbidities of patients with epilepsy.

Epilepsy Res 2011; 98:216-22. [PMID: 22005005 DOI: 10.1016/j.eplepsyres.2011.09.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2011] [Revised: 08/23/2011] [Accepted: 09/24/2011] [Indexed: 11/28/2022]
Abstract
The current study investigated the possible inherent relationship between convulsions and sleep involving the GABA(A)/benzodiazepine site complex. The aim of this study was to determine if rats with high (HTR) and low (LTR) thresholds for clonic convulsions induced by DMCM, a benzodiazepine inverse agonist, differ in the following aspects: (1) sensitivity to the hypnotic effects of the GABA(A) positive allosteric modulators diazepam, pentobarbital and ethanol and (2) in the binding of [(3)H]-flunitrazepam, a benzodiazepine agonist, measured by autoradiography, and [(3)H]-Ro 15-4513, a benzodiazepine partial inverse agonist, to membranes from discrete brain regions. The LTR subgroup presented a shorter diazepam-induced sleeping time compared to that of the HTR subgroup. Biochemical assays revealed that the LTR subgroup did not differ in [(3)H]-flunitrazepam binding compared to the HTR subgroup. With respect to the binding of [(3)H]-Ro 15-4513, the LTR subgroup had higher binding in the brainstem and lower binding in the striatum compared to the HTR subgroup. These results suggest that differences in the benzodiazepine site on the GABA(A) receptor may underlie the susceptibility to DMCM-induced convulsions and sensitivity to the hypnotic effect of diazepam.

Abstract
Multiple forms of the ketogenic diet (KD) have been successfully used to treat drug-resistant epilepsy, however its mainstream use as a first-line therapy is still limited. Further investigation into its clinical efficacy as well as the molecular basis of activity is likely to assist in the reversal of any resistance to its implementation. In this review we shall attempt to elucidate the current state of experimental and clinical data concerning the neuroprotective and cognitive effects of the KD in both humans and animals. Generally, it has been shown by many research groups that effective implementation of KD exerts strong neuroprotective effects with respect to social behavior and cognition. We will also elucidate the role of KD in the interesting relationship between sleep, epilepsy and memory. Currently available evidence also indicates that, under appropriate control, and with further studies investigating any potential long-term side effects, the KD is also a relatively safe intervention, especially when compared to traditional anti-epileptic pharmacotherapeutics. In addition, due to its neuroprotective capacity, the KD may also hold potential benefit for the treatment of other neurological or neurodegenerative disorders.

From sleep spindles of natural sleep to spike and wave discharges of typical absence seizures: is the hypothesis still valid? Pflugers Arch 2011; 463:201-12. [PMID: 21861061 PMCID: PMC3256322 DOI: 10.1007/s00424-011-1009-3] [Citation(s) in RCA: 61] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2011] [Revised: 07/22/2011] [Accepted: 08/01/2011] [Indexed: 11/15/2022]
Abstract
The temporal coincidence of sleep spindles and spike-and-wave discharges (SWDs) in patients with idiopathic generalized epilepsies, together with the transformation of spindles into SWDs following intramuscular injection of the weak GABAA receptor (GABAAR) antagonist, penicillin, in an experimental model, brought about the view that SWDs may represent ‘perverted’ sleep spindles. Over the last 20 years, this hypothesis has received considerable support, in particular by in vitro studies of thalamic oscillations following pharmacological/genetic manipulations of GABAARs. However, from a critical appraisal of the evidence in absence epilepsy patients and well-established models of absence epilepsy it emerges that SWDs can occur as frequently during wakefulness as during sleep, with their preferential occurrence in either one of these behavioural states often being patient dependent. Moreover, whereas the EEG expression of both SWDs and sleep spindles requires the integrity of the entire cortico-thalamo-cortical network, SWDs initiates in cortex while sleep spindles in thalamus. Furthermore, the hypothesis of a reduction in GABAAR function across the entire cortico-thalamo-cortical network as the basis for the transformation of sleep spindles into SWDs is no longer tenable. In fact, while a decreased GABAAR function may be present in some cortical layers and in the reticular thalamic nucleus, both phasic and tonic GABAAR inhibitions of thalamo-cortical neurons are either unchanged or increased in this epileptic phenotype. In summary, these differences between SWDs and sleep spindles question the view that the EEG hallmark of absence seizures results from a transformation of this EEG oscillation of natural sleep.

Abstract
The purpose of this study was to examine how sleep impacts memory function in temporal lobe epilepsy (TLE). Patients with TLE (n=7) and control subjects (n=9) underwent training and overnight testing on (1) a motor sequence task known to undergo sleep-dependent enhancement in healthy subjects, and (2) the selective reminding test, a verbal memory task on which patients with TLE have shown impaired performance 24 hours after training. Sleep data were collected by polysomnography. Results indicate that patients with TLE display greater forgetting on the selective reminding test compared with controls over 12 hours of daytime wakefulness, but not over a similar period including a night of sleep. Slow wave sleep is correlated with overnight performance change on the selective reminding test. Patients with TLE show no deficit in sleep-dependent motor sequence task improvement. The findings provide potential insight into the pattern and pathophysiology of forgetting in TLE.

Abstract
This study evaluated the sleep-wake pattern, plasma melatonin levels and the urinary excretion of its metabolite, 6-sulphatoxy-melatonin among children with severe epileptic disorders, before and after a therapeutic trial with melatonin. Ten paediatric patients, suffering from severe epileptic disorders, were selected and given a nightly dose of 3 mg of a placebo, for 1 wk; for the next 3 months, the placebo was replaced with a nightly dose of 3 mg of melatonin. At the end of each treatment period, the urinary excretion of 6-sulphatoxy-melatonin (for the intervals 09.00 - 21:00 hr or 21:00-09:00 hr) and plasma levels of melatonin (recorded at 01:00, 05:00, 09:00, 13:00, 17:00 and 21:00 hr) were recorded, over a period of 24 hr; an actigraph record was also kept. Sleep efficiency among patients who received melatonin was significantly higher than among those given the placebo, with fewer night-time awakenings. Periodic plasma melatonin levels were regained and a better control gained of convulsive episodes, in that the number of seizures decreased. We conclude that melatonin is a good regulator of the sleep-wake cycle for paediatric patients suffering from severe epilepsy, moreover, it to a better control of convulsive episodes.

Abstract
Sleep has long been considered as a passive phenomenon, but it is now clear that it is a period of intense brain activity involving higher cortical functions. Overall, sleep affects every aspect of a child's development, particularly higher cognitive functions. Sleep concerns are ranked as the fifth leading concern of parents. Close to one third of all children suffer from sleep disorders, the prevalence of which is increased in certain pediatric populations, such as children with special needs, children with psychiatric or medical diagnoses and children with autism or pervasive developmental disorders. The paper reviews sleep physiology and the impact, classification, and management of sleep disorders in the pediatric age group.

Abstract
Epilepsy and sleep disorders are considered by many to be common bedfellows. Several sleep phenomena may occur during nighttime taking a wide variety of forms and which can mimic seizures. Although most seizure sub-types have the potential to occur during sleep or wakefulness, sleep has a well-documented and strong association with specific epilepsy syndromes. Seizures in sleep also tend to occur during lighter stages of non-REM (NREM) sleep. The neurophysiologic process involved in the deepening of NREM sleep may also facilitate both seizures and IEDs. Epilepsy per se and/or seizures themselves promote sleep disruption and significantly affect the quality, quantity, and architecture of sleep. There are many causes of sleep disruption in patients with epilepsy, including inadequate sleep hygiene, coexisting sleep disorders, and circadian rhythm disturbances. Seizures themselves can disrupt sleep, even when they occur during wakefulness. Anti-epileptic drugs (AEDs) can also alter sleep in positive and negative ways, and these effects are independent of anticonvulsant actions. The end result of sleep disruption is excessive daytime sleepiness, worsening seizures, and poor quality of life. Screening for sleep disorders in the epilepsy population and appropriate intervention strategies will lead to overall improved quality of life and seizure control.

Abstract
This 6-month observational, prospective, multicenter study assessed the influence of changes in seizure severity on quality of life in patients with refractory partial epilepsy. Patients (N = 262) diagnosed with partial epilepsy and receiving two antiepileptic drugs as determined by usual clinical practice were enrolled in this study. The primary endpoint was the mean seizure severity score obtained from the Seizure Severity Questionnaire. Reductions in seizure severity were detected from baseline to months 3 and 6 (P<0.0001). Improvements compared with baseline were found for several secondary measures: Hamilton Anxiety and Depression scales (P<0.0001), most Medical Outcomes Study-Sleep subscales (P<0.05), and seven subscales of the Quality of Life in Epilepsy Inventory-31 (QOLIE-31; P<0.0005). Seizure severity correlated directly with anxiety (P<0.0001) and inversely with QOLIE-31 measures (P<0.0001). In conclusion, reducing seizure severity with appropriate medication may lead to improvement in the overall quality of life of patients with refractory partial epilepsy.

Abstract
The pathophysiology of Sturge-Weber syndrome is poorly understood, and ear, nose, and throat involvement is possible. These issues can result in frequent illnesses or airway obstruction, affecting patients' neurologic status. Patients with definite brain involvement who reported potential ear, nose, and throat issues on intake questionnaires underwent retrospective reviews of their medical records. We examined the relationships between these issues, secondary surgical interventions, and patients' neurologic status. The most common complaints involved the sinuses and frequent ear infections. Six patients underwent placement of ear tubes, leading to improvements in migraines and stroke-like episodes in one patient, and improved seizure control in four others. Obstructive sleep apnea was confirmed in three patients who underwent sleep studies. Tonsil or adenoid removal occurred in another three patients. Surgery resulted in marked improvements regarding excessive drooling, daytime sleepiness, and breathing problems. These findings suggest that ear, nose, and throat problems occur frequently in patients with Sturge-Weber Syndrome, and when repeated ear infections are associated with uncontrolled seizures, early placement of ear tubes may be beneficial. Furthermore, patients with facial tissue hypertrophy may be at risk for obstructive sleep apnea, and should be appropriately evaluated.

Abstract
A 23-year-old woman without history of antecedent vocal, respiratory, or sleep disorders received vagus nerve stimulation (VNS) therapy for refractory partial epilepsy and developed sleep-related stridor during the course of parameter titration. Reduction of VNS current during polysomnography completely eliminated stridor. We conclude that VNS may cause sleep-related stridor in rare cases, expanding the spectrum of known sleep-disordered breathing disorders associated with VNS therapy. Parameter adjustment during polysomnography may resolve nocturnal stridor caused by VNS.

Abstract
OBJECTIVE Growing interest in seizure prediction exists as a means to deliver newer antiepileptic therapies, though patient self-termination of seizures has received little attention. METHODS Two hundred twenty-three patients able to recognize seizure onset were surveyed in an outpatient epilepsy clinic. A seven-question survey administered prospectively assessed self-reported seizure prediction and clinical techniques used for self-termination. Survey responses targeted percentage predictability of seizures, timing of clinical prediction, likelihood/timing of termination, frequency and effectiveness of methods used, and perspectives of patient and physician belief in self-termination. RESULTS Two hundred twenty-three patients (89 males) with a mean age of 42.7 years, average duration of epilepsy of 20.8 years and monthly mean seizure frequency of 4.1 comprised the study group. Thirty-eight percent completed >75% of the survey. Prior treatment included a mean of 6.0 AEDs (40/192 had surgery); 65% had ongoing seizures. Sixty percent of 223 patients reported a history of an aura, and 39% consistently noted auras for >75% of their current seizures. Of the patients with auras, seizure triggers were reported in 74%, with worry and stress (N=69), sleep deprivation (N=60), and missed medication (N=56) most frequently cited. Seventeen percent were positive/somewhat sure they could predict onset, with approximately 20% noting rapid onset in <15 seconds. Twenty-two of 82 noted that they had some ability to self-terminate their seizures, and 9% were positive that they could do so. Methods to self-terminate were effective (>75% certainty) in 35% (26/75). The primary methods were lying down/resting and taking extra medication. CONCLUSION The majority of patients with partial seizures recognize triggers of seizure onset. In addition, more than one-third believe they can effectively self-terminate their partial-onset seizures. Lying down, resting, and taking extra medication were the most common techniques instituted by patients. Correlating clinical symptoms at seizure onset with termination may help improve the sensitivity in seizure prediction.

Abstract
The aim of the study was to evaluate excessive daytime sleepiness and subjective sleep quality in patients who undergo epilepsy surgery for treatment of refractory partial seizures. Forty-eight patients were enrolled in this research study. All of them were evaluated 2 days before and 3 months after the surgery. Two questionnaires were used to assess daytime sleepiness (Epworth Sleepiness Scale [ESS]) and sleep quality (Pittsburgh Sleep Quality Index [PSQI]). Global PSQI was high (mean=5.65 SD=3.71) before the surgical procedure (P<0.001). PSQI evaluation revealed higher and statistically significant scores in three components as well as in the global score, when analyzed by predominance of daytime or nocturnal seizures. ESS and PSQI scores were also analyzed by gender, antiepileptic drug class, age, and seizure frequency, with no significant differences. We concluded that patients with partial recurrent seizures of temporal origin have poor subjective sleep quality that improves significantly after epilepsy surgery.
