Abstract
PURPOSE Managing epilepsy may require using more than one anti-seizure medication (ASM). While combination therapy may help, risks, including psychiatric problems, are not fully explored in Africa. We examined the relationship between polytherapy and psychiatric comorbidities among attendees of an epilepsy community clinic. METHODS We prospectively assessed individuals attending an outpatient clinic in Kilifi, Kenya, for patterns of ASM prescribing (mono- or polytherapy) and reviewed psychiatric diagnoses. We used the Psychosis Screening Questionnaire and the Patient Health Questionnaire Version 9 to assess for psychosis and depression, and the Child Behavior Checklist to assess for emotional and behavioural problems. We conducted a cross-sectional logistic regression analysis to determine factors associated with polytherapy and examine the impact of polytherapy and specific medication on psychiatric comorbidities. RESULTS Of 3,016 attendees, most were on older ASM (99.7 %), with about a third (32.9 %) on polytherapy. The most commonly co-administered drugs were phenobarbital and carbamazepine (13.0 %). Children were less likely to be on multiple medications than adults, and there was no difference between the sexes. Polytherapy was associated with focal to bilateralised seizures (aOR 1.2 [95 % confidence interval:1.0-1.4]) and frequent seizures (aOR = 2.1 [1.5-2.9]). Combining drugs increased the likelihood of any psychiatric problems (aOR = 1.3 [1.0-1.8]), with polytherapy associated with depression (aOR = 2.9 [1.0-8.4]) and psychosis (aOR = 1.9 (1.0-3.6)). CONCLUSION Polytherapy, especially with older drugs, is associated with psychiatric comorbidities in this population. Resorting to polytherapy needs to be carefully considered. Prioritizing research into the long-term effects of ASM on psychiatric comorbidities is crucial for improving mental health outcomes in epilepsy, particularly in low-income settings.

Epilepsy Behav 2024; 161:110143. [PMID: 39515005 DOI: 10.1016/j.yebeh.2024.110143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2024] [Revised: 10/18/2024] [Accepted: 11/02/2024] [Indexed: 11/16/2024]
Abstract
INTRODUCTION Children with childhood absence epilepsy (CAE) are deemed to be at higher risk of attention deficit hyperactivity disorder (ADHD), however the magnitude of that risk has not been assessed in a population-based study. METHODS The Rochester Epidemiology Project database was used to identify children with a new diagnosis of CAE while resident in Olmsted County, MN between 1980-2018. For each case, four age- and sex-matched controls without epilepsy were identified. Records of cases and controls screening positive for ADHD were reviewed to confirm this diagnosis. Those with comorbid ADHD and CAE were further assessed to determine if the ADHD diagnosis preceded or followed the epilepsy diagnosis, as well as the impact of ADHD treatment on possible seizure exacerbation and long-term epilepsy course. RESULTS Forty-one cases of CAE were identified and matched to 164 controls. ADHD was diagnosed in 17 children (41.5 %) with CAE and 12 controls (7.3 %) (p < 0.001). Compared to those without epilepsy, the diagnosis of ADHD in CAE was more likely to be made by a mental health professional than a primary care provider (p = 0.047). ADHD in CAE typically followed the diagnosis of CAE and in 7/17 cases, was diagnosed after remission of epilepsy and discontinuation of antiseizure medication. There was no difference in the proportion of cases or controls treated with ADHD medication (16/17 cases and 12/12 controls). Both groups had high likelihood of favorable response to ADHD medication and no child with CAE experienced seizure exacerbation with ADHD treatment. CONCLUSIONS ADHD was 5.7-fold more common in CAE then in children without epilepsy in our population-based study. Treatment with stimulants is highly effective and not associated with worsening of seizures. Primary care providers must be vigilant to carefully screen this population for ADHD.

Abstract
Psychiatric and cognitive comorbidities have been known to play a major role in human epilepsy for a long time. People with epilepsy (PWE) frequently express signs of varying psychiatric and cognitive disorders affecting their quality and quantity of life (QoL/QaoL). Over the last few years, research on behavioural comorbidities and their effect on the underlying disease have been performed in canine epilepsy. The following article reviews manifestations of comorbidities in canine epilepsy with an emphasis on patterns of clinical signs and their effects on QoL and QaoL. Cognitive and behavioural alterations in epileptic dogs are mainly represented by fear-/anxiety related behaviour and cognitive impairment (CI). Reduced trainability and altered reactions to daily situations are common results of comorbid changes posing obstacles in everyday life of owners and their dog. In addition, clinical signs similar to attention deficit hyperactivity disorder (ADHD) in humans have been reported. Canine attention-deficit-hyperactivity-disorder-like (c-ADHD-like) behaviour should, however, be evaluated critically, as there are no official criteria for diagnosis of ADHD or ADHD-like behaviour in dogs, and some of the reported signs of c-ADHD-like behaviour could be confused with anxiety-associated behaviour. Many intrinsic and extrinsic factors could potentially influence the development of behavioural and cognitive comorbidities in canine epilepsy. In particular, seizure frequency/severity, signalment and factors concerning disease management, such as pharmacotherapy and nutrition, are closely linked with the presence of the aforementioned comorbid disorders. Further studies of behavioural alterations in epileptic dogs are needed to comprehend the complexity of clinical signs and their multifactorial origin.

Abstract
Objective: Anxiety is among the most common psychiatric illnesses, and it commonly co-occurs with epilepsy. This review of the existing literature on anxiety comorbid with epilepsy aims to generate new insights into strategies for assessment and treatment. Methods: The authors conducted a narrative literature review to select key publications that help clarify the phenomenology and management of comorbid anxiety and epilepsy. Results: Anxiety symptoms may be relevant even if the criteria for a diagnosis of an anxiety disorder are not met. Associating specific seizure types or seizure localization with anxiety symptoms remains difficult; however, the amygdala is a brain region commonly associated with seizure foci and panic or fear sensations. The hypothalamic-pituitary-adrenal axis may also be relevant for anxiety symptoms, particularly for the selection of treatments. Nonpharmacological treatment is appropriate for anxiety comorbid with epilepsy, particularly because relaxation techniques may reduce hypersympathetic states, which improve symptoms. Medication options include antidepressants and anticonvulsants that may have efficacy for anxiety symptoms. Benzodiazepines are a good choice to address this comorbid condition, although side effects may limit utility. Conclusions: Ultimately, there are numerous treatment options, and although there is a limited evidence base, quality of life may be improved with appropriate treatment for individuals experiencing comorbid anxiety and epilepsy.

Abstract
BACKGROUND Binge-eating disorder (BED) is a common psychiatric condition with adverse psychological and metabolic consequences. Lisdexamfetamine (LDX) is the only approved BED drug treatment. New drugs to treat BED are urgently needed. METHODS A comprehensive review of published psychopathological, pharmacological and clinical findings. RESULTS The evidence supports the hypothesis that BED is an impulse control disorder with similarities to ADHD, including responsiveness to catecholaminergic drugs, for example LDX and dasotraline. The target product profile (TPP) of the ideal BED drug combines treating the psychopathological drivers of the disorder with an independent weight-loss effect. Drugs with proven efficacy in BED have a common pharmacology; they potentiate central noradrenergic and dopaminergic neurotransmission. Because of the overlap between pharmacotherapy in attention deficit hyperactivity disorder (ADHD) and BED, drug-candidates from diverse pharmacological classes, which have already failed in ADHD would also be predicted to fail if tested in BED. The failure in BED trials of drugs with diverse pharmacological mechanisms indicates many possible avenues for drug discovery can probably be discounted. CONCLUSIONS (1) The efficacy of drugs for BED is dependent on reducing its core psychopathologies of impulsivity, compulsivity and perseveration and by increasing cognitive control of eating. (2) The analysis revealed a large number of pharmacological mechanisms are unlikely to be productive in the search for effective new BED drugs. (3) The most promising areas for new treatments for BED are drugs, which augment noradrenergic and dopaminergic neurotransmission and/or those which are effective in ADHD.

Abstract
Binge-eating disorder (BED) is the commonest eating disorder and an important causal factor in obesity. Lisdexamfetamine is the only approved pharmacological treatment. Many drugs have been clinically evaluated and several were described as potentially promising treatments. A comprehensive reassessment of the evidence from these clinical trials has been performed. The questions to be answered were: (1) Does the evidence support claims of efficacy? (2) What pharmacological mechanisms show promise for developing new BED drugs? (3) What are the clinical implications for treating BED? PubMed and internal database searches identified every available published drug trial in BED. The trials and their results were summarised and reviewed to re-evaluate the evidence. Factors taken into consideration included psychiatric diagnosis, primary endpoint, secondary outcome measures, trial size, blinding and controls, drop-out rates, placebo response rates and weight-loss. Drugs were classified according to their pharmacology and therapeutic indication to determine which mechanisms were effective and to provide insights into the psychopathology of BED. For most drugs, robust evidence of efficacy in BED is insubstantial or absent. Some catecholaminergic drugs developed for ADHD are also effective in BED; other pharmacological mechanisms are weakly efficacious at best. Reducing BED severity has little impact on weight. Conversely, weight-loss from anti-obesity therapy is ineffective in ameliorating the psychopathological drivers of BED. (1) BED is a psychiatric not a metabolic disorder. (2) Weight-loss drugs are generally ineffective in BED. (3) Efficacy in BED is restricted to powerful catecholaminergic drugs. (4) Drugs acting via noradrenaline, 5-HT, GABA, carbonic anhydrase inhibition, opioid receptors and various ion channels are generally minimally effective at best. (5) Efficacy in BED is dependent on treating its core psychopathology; reducing impulsivity and compulsivity and increasing cognitive restraint over eating. (6) Obese subjects with BED may benefit from separate treatments for these two disorders.

Abstract
One of the drugs used to treat attention deficit hyperactivity syndrome is atomoxetine. Usually, the drug is well tolerated but in rare cases adverse advents may occur. An 18-year-old female under atomoxetine (60 mg/d) since 2 years for attention deficit hyperactivity syndrome since age 13 years, developed sudden onset headache, hemianopia to the right, hypoesthesia of the tongue and right arm, aphasia, and depersonalisation. Blood tests revealed hyper-CK-emia of 2860U/L, cerebral magnetic resonance imaging showed disturbed perfusion on the left temporo-parieto-occipital region, and electroencephalography (EEG) revealed focal slowing and spikes and sharp waves in the same projections. After discontinuation of atomoxetine, symptoms, EEG, and magnetic resonance imaging findings resolved spontaneously within 48 hours. In conclusion, atomoxetine may rarely cause severe side effects such as complex partial seizures with CK-elevation, transient hypoperfusion of the temporal, parietal and occipital lobes, and prolonged reorientation. Atomoxetine should be discontinued if such side effects occur.

Abstract
Background Individuals with Down syndrome are predisposed to a number of chronic health conditions, but the relationship between these conditions and cognitive ability is not clear. The primary objective of this systematic review is to assess this relationship by evaluating studies that measure cognitive performance in the context of Down syndrome-associated chronic health conditions. Methods A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Studies included in this review (1) included children, adolescent, and young adult participants with Down syndrome and one or more co-occurring health conditions; (2) were quantitative; and (3) reported outcomes related to both chronic health conditions and cognitive performance. A set of predetermined chronic health conditions that are common in Down syndrome (e.g. sleep disorders, congenital heart disease, thyroid disease, seizure disorders, and pulmonary hypertension) were selected based on prevalence rates in Down syndrome. Results Fifteen studies met inclusion criteria. The majority these of studies assessed cognitive performance in association with sleep disorders (47%) and congenital heart disease (47%). Fewer studies reported on the effect of thyroid disease (7%) and seizure disorders (7%) on cognitive ability. None of the studies reported cognitive outcomes related to pulmonary hypertension. Of the chronic health conditions evaluated, associations between sleep disorders and cognitive dysfunction were most common among individuals with Down syndrome. Conclusions Individuals with Down syndrome exhibit deficits in cognitive ability, particularly related to attention, executive function and verbal processing. These deficits may be further exacerbated by the presence of chronic health conditions, particularly sleep disorders. Individuals with Down syndrome and co-occurring sleep disorders may benefit from early interventions to mitigate their risk for adverse cognitive outcomes.

Abstract
Pediatric epilepsy is a prevalent childhood neurological disorder. Youth with a diagnosis of medically uncontrollable or intractable epilepsy are at increased risk for poor neurocognitive and psychosocial functioning. To date, there is a paucity of clinical research examining and/or characterizing the relations of neuropsychological, clinical, and epilepsy-specific medical factors in clinical outcomes among youth with diagnosed intractable epilepsy. One hundred and twenty-six patients (6-20 years) with diagnosed intractable epilepsy and who were evaluated as part of a presurgical work-up and medical standard of care participated in a neuropsychological evaluation, including parent completion of the Behavior Assessment System for Children - Second Edition Parent Report Scale (BASC-2 PRS). Medical chart review was conducted to obtain demographic and epilepsy-specific information. Results indicated that an increase in the BASC-2 PRS Adaptive Symptoms Index T-Scores was associated with a decrease in the BASC-2 PRS Internalizing, Externalizing, and Behavioral Symptoms Index score. Additionally, the Wechsler (Wechsler Intelligence Scale for Children - Fourth Edition [WISC-IV], Wechsler Intelligence Scale for Children - Fifth Edition [WISC-V], Wechsler Adult Intelligence Scale - Fourth Edition [WAIS-IV]) Similarities z-score was associated with the BASC-2 PRS Externalizing Symptoms Index T-Score. No demographic or clinical medical factors remained in any of the three final models. Findings highlight the importance of verbal reasoning and adaptive functioning as protective factors in clinical outcomes among youth with diagnosed intractable epilepsy and may provide future direction for targeted interventions.

Attention deficit hyperactivity disorder (ADHD) is a psychiatric condition that affects attention, concentration, impulse control and awareness. Not only these symptoms, but also the medications used to treat ADHD (psychostimulants) pose a risk to both the diver and his or her buddy. This article presents guidelines for recreational diving in combination with ADHD and psychostimulants. These guidelines are based solely on 'expert' opinion and were adopted at a meeting of the Dutch Association for Diving Medicine in 2017.

Abstract
This study aimed to assess the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) and its characteristics and risk factors in children with epilepsy at a tertiary medical center in New Delhi. Children with active epilepsy, aged 6 to 12 years, were assessed for ADHD using DSM-IV-TR criteria. Epilepsy and psychiatric characteristics, sociodemographic indicators, and use of antiepileptic drugs were analyzed for differences between the ADHD and non-ADHD groups. Among the 73 children with epilepsy, 23% (n = 17) had comorbid ADHD, of whom 59% (n = 10) had predominantly inattentive type, 35% (n = 6) combined type, and 6% (n = 1) predominantly hyperactive-impulsive type. Lower IQ scores, epileptiform EEG activity, not attending school, and male sex were significantly associated with comorbid ADHD in children with epilepsy. Groups were similar in terms of age, socioeconomic indicators, family history of psychiatric disorders, seizure frequency in the last six months, seizure etiology, and seizure type. Epilepsy is a common pediatric neurological condition with frequent psychiatric comorbidities, including ADHD. Specialists should collaborate to optimize treatment for children with epilepsy and ADHD, especially for families in developing countries where the burden of disease can be great.

Abstract
BACKGROUND Epilepsy and attention-deficit/hyperactivity disorder (ADHD) are strongly associated; however, the underlying factors contributing to their co-occurrence remain unclear. A shared genetic liability has been proposed as one possible mechanism. Therefore, our goal in this study was to investigate the familial coaggregation of epilepsy and ADHD and to estimate the contribution of genetic and environmental risk factors to their co-occurrence. METHODS We identified 1,899,654 individuals born between 1987 and 2006 via national Swedish registers and linked each individual to his or her biological relatives. We used logistic regression to estimate the association between epilepsy and ADHD within individual and across relatives. Quantitative genetic modeling was used to decompose the cross-disorder covariance into genetic and environmental factors. RESULTS Individuals with epilepsy had a statistically significant increased risk of ADHD (odds ratio [OR] = 3.47, 95% confidence interval [CI] = 3.33-3.62). This risk increase extended to children whose mothers had epilepsy (OR = 1.85, 95% CI = 1.75-1.96), children whose fathers had epilepsy (OR = 1.64, 95% CI = 1.54-1.74), full siblings (OR = 1.56, 95% CI = 1.46-1.67), maternal half siblings (OR = 1.28, 95% CI = 1.14-1.43), paternal half siblings (OR = 1.10, 95% CI = 0.96-1.25), and cousins (OR = 1.15, 95% CI = 1.10-1.20). The genetic correlation was 0.21 (95% CI = 0.02-0.40) and explained 40% of the phenotypic correlation between epilepsy and ADHD, with the remaining variance largely explained by nonshared environmental factors (49%, nonshared environmental correlation = 0.36, 95% CI = 0.23-0.49). The contribution of shared environmental factors to the cross-disorder overlap was not statistically significant (11%, shared environmental correlation = 0.32, 95% CI = -0.16-0.79). CONCLUSIONS This study demonstrates a strong and etiologically complex association between epilepsy and ADHD, with shared familial factors and risk factors unique to the individual contributing to co-occurrence of the disorders. Our findings suggest that epilepsy and ADHD may share less genetic risk as compared with other neurodevelopmental disorders.

[PMID: 26773515 DOI: 10.1016/j.yebeh.2015.11.014] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2015] [Revised: 11/09/2015] [Accepted: 11/14/2015] [Indexed: 12/18/2022]
Abstract
OBJECTIVES Epilepsy in humans and rodent models of epilepsy can be associated with behavioral comorbidities including an increased prevalence of attention-deficit/hyperactivity disorder (ADHD). Attention-deficit/hyperactivity disorder symptoms and seizure frequency have been successfully reduced in humans and rodents using a ketogenic diet (KD). The aims of this study were (i) to describe the behavioral profile of dogs with idiopathic epilepsy (IE) while on a standardized nonketogenic placebo diet, to determine whether ADHD-like behaviors are present, and (ii) to examine the effect of a ketogenic medium chain triglyceride diet (MCTD) on the behavioral profile of dogs with idiopathic epilepsy (IE) compared with the standardized placebo control diet, including ADHD-like behaviors. METHODS A 6-month prospective, randomized, double-blinded, placebo-controlled, crossover dietary trial comparing the effects of the MCTD with a standardized placebo diet on canine behavior was carried out. Dogs diagnosed with IE, with a seizure frequency of at least 3 seizures in the past 3months (n=21), were fed the MCTD or placebo diet for 3months and were then switched to the alternative diet for 3months. Owners completed a validated behavioral questionnaire to measure 11 defined behavioral factors at the end of each diet period to report their dogs' behavior, with three specific behaviors hypothesized to be related to ADHD: excitability, chasing, and trainability. RESULTS The highest scoring behavioral factors in the placebo and MCTD periods were excitability (mean±SE: 1.910±0.127) and chasing (mean±SE: 1.824±0.210). A markedly lower trainability score (mean±SE: 0.437±0.125) than that of previously studied canine populations was observed. The MCTD resulted in a significant improvement in the ADHD-related behavioral factor chasing and a reduction in stranger-directed fear (p<0.05) compared with the placebo diet. The latter effect may be attributed to previously described anxiolytic effects of a KD. CONCLUSIONS These data support the supposition that dogs with IE may exhibit behaviors that resemble ADHD symptoms seen in humans and rodent models of epilepsy and that a MCTD may be able to improve some of these behaviors, along with potentially anxiolytic effects.

Methylphenidate improves the quality of life of children and adolescents with ADHD and difficult-to-treat epilepsies. Epilepsy Behav 2015; 46:215-20.

Abstract
OBJECTIVE Comorbidity between difficult-to-treat epilepsies and ADHD is frequent and impacts negatively on quality of life. The commonly held (yet poorly substantiated) view that stimulants may worsen seizure control has prevented studies from evaluating the impact of such treatment in this population. Our aim was to study the effect of methylphenidate on the quality of life of children and adolescents with difficult-to-treat epilepsies and comorbid ADHD. METHODS The study was an open-label, noncontrolled trial with intention-to-treat analysis following 30 patients for 6months. Subjects received methylphenidate following 3months of baseline, during which antiepileptic drugs (AEDs) were adjusted and epilepsy, ADHD, and quality-of-life variables were assessed. Multivariate regression analysis identified the main variables correlated with outcome. RESULTS Only one patient withdrew because of seizure worsening. Following methylphenidate introduction, doses were titrated up to 0.40-0.50mg/kg/day. A marked improvement in quality-of-life scores and a significant reduction in seizure frequency and severity were observed. Female sex, reduction of core ADHD symptoms, and tolerability to adequate doses of methylphenidate were significantly associated with improved quality-of-life scores. CONCLUSION These preliminary data suggest that methylphenidate treatment is safe and effective in patients with ADHD and difficult-to-treat epilepsies, positively impacting on quality-of-life scores.

Behav Brain Res 2014; 278:542-8. [PMID: 25446754 DOI: 10.1016/j.bbr.2014.10.050] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2014] [Revised: 10/27/2014] [Accepted: 10/30/2014] [Indexed: 02/07/2023]
Abstract
Autism is a complex neurodevelopmental disorder that is characterized by social abnormalities. Genetic, dietary and gut-related factors are implicated in autism, however the causal properties of these factors and how they may interact are unclear. Propionic acid (PPA) is a product of gut microbiota and a food preservative. PPA has been linked to autism, and PPA administration to rats is an animal model of the condition. Seizure-prone (FAST) and seizure-resistant (SLOW) rats were initially developed to investigate differential vulnerability to developing epilepsy. However, FAST rats also display autistic-like features, and have been proposed as a genetic model of autism. Here we examined the effects of PPA on social behavior in FAST and SLOW rats. A single intracerebroventricular injection of PPA, or phosphate-buffered saline (PBS), was administered to young-adult male FAST and SLOW rats. Immediately after treatment, rats were placed in same-treatment and same-strain pairs, and underwent social behavior testing. PPA induced social abnormalities in both FAST and SLOW rat strains. While there was no evidence of social impairment in FAST rats that were not treated with PPA, these rats were hyperactive relative to SLOW rats. Post-mortem immunofluorescence analysis of brain tissue indicated that PPA treatment resulted in increased astrogliosis in the corpus callosum and cortex compared to PBS treatment. FAST rats had increased astrogliosis in the cortex compared to SLOW rats. Together these findings support the use of PPA as a rat model of autism, but indicate there are no interactive effects between the PPA and FAST models.

Abstract
Examine the hospital admission risk in young children who are subsequently diagnosed with attention deficit hyperactivity disorder (ADHD). We conducted a population-based, record linkage study. Records of all non-Aboriginal children under 18 years who met the DSMIV/ICD10 criteria for ADHD and prescribed stimulant medication in Western Australia between 2003 and 2007 (n = 11,902) were linked to two other health data systems-the hospital morbidity data system and the midwives notification system (MNS). The non-ADHD reference population (n = 27,304) was randomly selected from the MNS. Compared with controls, children under 4 years who subsequently were diagnosed and treated for ADHD were 70% [odds ratio (OR) 1.70; 95% confidence intervals (CI) 1.62-1.77] more likely to be admitted to hospital under 4 years of age. There was an increased risk for injury or poison (OR 1.73; 95% CI 1.59-1.88), respiratory disease (OR 1.49; 95% CI 1.40-1.59), ear disease (OR 2.03; 95% CI 1.86-2.21), infectious diseases (OR 1.68; 95% CI 1.53-1.85) and neurological conditions (OR 2.03; 95% CI 1.68-2.44). Admissions under 4 years of age for head injuries, burns, poisons, all other injuries, diseases of the tonsils and adenoids, asthma and early infections were all more common amongst children subsequently diagnosed with and treated for ADHD. There is significant early hospital morbidity for children subsequently diagnosed with ADHD. Multiple aetiologies and causal pathways need to be considered where some of these may include early infections, inflammatory conditions, epilepsy and injuries. Future studies should look at which of these conditions may be on the causal pathway or likely early markers for ADHD.

Abstract
The objective was to investigate the prevalence of attention-deficit hyperactivity disorder (ADHD) in children with frontal lobe epilepsy and related factors. The medical records of 190 children diagnosed with frontal lobe epilepsy at Qilu Hospital of Shandong University between 2006 and 2011 were retrospectively collected, and a follow-up analysis of the prevalence of ADHD in these children was conducted. Of the 161 children with an effective follow-up, 59.0% (95/161) with frontal lobe epilepsy suffered from ADHD as well. Analysis of epilepsy and ADHD-related factors indicated that the incidence of ADHD was 89.4% (76/85) in children with abnormal electroencephalogram (EEG) discharges on the most recent EEG, which was significantly higher than the ADHD incidence of 25% (19/76) in children with normal readings on the most recent EEG (P < .01). Children with frontal lobe epilepsy have a high incidence of ADHD. Sustained abnormal discharge on the electroencephalogram is associated with increased comorbidity of ADHD with frontal lobe epilepsy.

Abstract
PURPOSE To establish the efficacy and safety of methylphenidate (MPH) treatment for attention deficit hyperactivity disorder (ADHD) in a group of children and young people with learning disability and severe epilepsy. METHODS This retrospective study systematically reviewed the case notes of all patients treated with methylphenidate (MPH) for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) ADHD at a specialist epilepsy center between 1998 and 2005. Treatment efficacy was ascertained using clinical global impressions (CGI) scores, and safety was indexed by instances of >25% increase in monthly seizure count within 3 months of starting MPH. KEY FINDINGS Eighteen (18) patients were identified with refractory epilepsies (14 generalized, 4 focal), IQ <70, and ADHD. Male patients predominated (13:5) and ADHD was diagnosed at a median age of 11.5 years (range 6–18 years). With use of a combination of a behavioral management program and MPH 0.3–1 mg/kg/day, ADHD symptoms improved in 61% of patients (11/18; type A intraclass correlation coefficient of CGI 0.85, 95% confidence interval [CI] 0.69–0.94). Daily MPH dose, epilepsy variables, and psychiatric comorbidity did not relate to treatment response across the sample. MPH adverse effects led to treatment cessation in three patients (dysphoria in two, anxiety in one). There was no statistical evidence for a deterioration of seizure control in this group with the use of MPH. SIGNIFICANCE Methylphenidate with behavioral management was associated with benefit in the management of ADHD in more than half of a group of children with severe epilepsy and additional cognitive impairments. Eighteen percent had significant side effects but no attributable increase in seizures. Methylphenidate is useful in this group and is likely to be under employed.

Abstract
BACKGROUND Medication is an important element of therapeutic strategies for ADHD. While medications for ADHD are generally well-tolerated, there are common, although less severe, as well as rare but severe adverse events AEs during treatment with ADHD drugs. The aim of this review is to provide evidence- and expert-based guidance concerning the management of (AEs) with medications for ADHD. METHODS For ease of use by practitioners and clinicians, the article is organized in a simple question and answer format regarding the prevalence and management of the most common AEs. Answers were based on empirical evidence from studies (preferably meta-analyses or systematic reviews) retrieved in PubMed, Ovid, EMBASE and Web of Knowledge through 30 June 2012. When no empirical evidence was available, expert consensus of the members of the European ADHD Guidelines Group is provided. The evidence-level of the management recommendations was based on the SIGN grading system. RESULTS The review covers monitoring and management strategies of loss of appetite and growth delay, cardiovascular risks, sleep disturbance, tics, substance misuse/abuse, seizures, suicidal thoughts/behaviours and psychotic symptoms. CONCLUSION Most AEs during treatment with drugs for ADHD are manageable and most of the times it is not necessary to stop medication, so that patients with ADHD may continue to benefit from the effectiveness of pharmacological treatment.

Abstract
It is well-known that the prevalence of attention deficit hyperactivity disorder (ADHD) is higher in epileptic children than in the general pediatric population. The aim of this study was to compare the accompaniment of ADHD in epileptic children with well-controlled seizures and no significant intellectual disability with that in healthy controls. We included epileptic children between the ages of 6 and 12 yr visiting our clinic for six consecutive months and controls without significant medical or psychiatric illnesses. We excluded patients with intellectual disability or persistent seizures during the recent three months. The diagnosis of ADHD was based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). After exclusion of 84 patients, we enrolled 102 (54.8%) children (mean age, 9.4 ± 2.0 yr). Seven (7 of 102, 6.9%) were diagnosed with ADHD. As compared to control group (4 of 110, 3.6%), there was no difference in ADHD accompaniment (P = 0.29). No difference was observed in ADHD accompaniment according to seizure type and epilepsy syndrome. In conclusion, the accompaniment of ADHD in epileptic children with well-controlled seizures and no intellectual disability may not differ from that of the general pediatric population.

Abstract
OBJECTIVES: To describe the prevalence of ADHD in mothers of children with comorbid ADHD and epilepsy (ADHD+E) and to compare ADHD symptoms in mothers with (Fam(+)) and without (Fam(-)) additional relative(s) with epilepsy. PATIENTS & METHODS: Mothers (n = 16) of children with ADHD+E were assessed by the Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children ADHD module and the ADHD Rating Scale IV. Information was collected on the presence (Fam(+)) or absence (Fam(-)) of first- or second-degree relatives with epilepsy in the sample. RESULTS: A total of 50% of mothers met the DSM-IV criteria for ADHD. ADHD was more prevalent in Fam(+) mothers (80%) compared with Fam(-) mothers (36%; p = 0.14). Fam(+) mothers had more current hyperactivity symptoms than Fam(-) mothers (p = 0.002), higher current ADHD severity (p = 0.02) and higher ADHD Rating Scale IV hyperactivity scores (p = 0.008). CONCLUSION: The prevalence of ADHD in mothers of children with ADHD+E is elevated in this pilot study, suggesting that ADHD symptoms in children with epilepsy and their mothers reflects shared familial genetic or environmental risks, potentially resulting in a higher prevalence of both disorders among family members. This is a pilot study and larger controlled studies are warranted.

Abstract
SLC9A9 (solute carrier family 9, member 9, also known as Na+/H+ exchanger member (NHE9)) is a membrane protein that regulates the luminal pH of the recycling endosome, an essential organelle for synaptic transmission and plasticity. SLC9A9 has been implicated in human attention deficit hyperactivity disorder (ADHD) and in rat studies of hyperactivity. We examined the SLC9A9 gene sequence and expression profile in prefrontal cortex, dorsal striatum and hippocampus in two genetic rat models of ADHD. We report two mutations in a rat model of inattentive ADHD, the WKY/NCrl rat, which affect the interaction of SLC9A9 with calcineurin homologous protein (CHP). We observed an age-dependent abnormal expression of SLC9A9 in brains of this inattentive model and in the Spontaneous Hypertensive Rat (SHR) model of ADHD. Our data suggest a novel mechanism whereby SLC9A9 sequence variants and abnormalities in gene expression could contribute to the ADHD-like symptoms of rat models and possibly the pathophysiology of ADHD in humans.

Abstract
Pediatric epilepsy is a common, chronic, and challenging physical illness for children and their families. This article provides a medical overview and discusses the cognitive functioning and psychosocial adjustment as well as the psychiatric management for children and adolescents with pediatric epilepsy. The management of these children involves establishing a collaborative health care approach, evaluating academic functioning, considering psychotherapy, and managing psychopharmacologic treatment. A thorough understanding of the biopsychosocial concerns in pediatric epilepsy can enable medical providers and mental health clinicians to promote resiliency and adaptation in children and their families facing troubling seizure disorders.

Abstract
An electroencephalogram (EEG) has not been routinely utilized in the evaluation of children with attention deficit hyperactivity disorder (ADHD). The utility of the EEG in ADHD is unclear. A recent study in our laboratory using sleep and sleep deprivation routinely found one in four non-epileptic children evaluated for attention deficit disorder has epileptiform discharges in the EEG, more than half focal. The majority of abnormalities (97.5%) occur in sleep and sleep-deprived records compared to 7% in prior wake only records. A review of eight publications showed that laboratories using awake only as routine EEG recordings report a relatively low prevalence of epileptiform discharges, whereas the higher prevalence of epileptiform discharges is seen in those with more prolonged sleep recordings. We have determined that sleep deprivation and sleep are essential to rule out an abnormal EEG in attention deficit disorder. In patients with attention deficit disorder complicated by epilepsy, stimulant therapy is generally safe, provided seizures are controlled by antiepileptic medication. Patients with epilepsy or subclinical electrographic abnormalities not treated with anticonvulsants are at increased risk of seizures when stimulant therapy is introduced, especially extended-release methylphenidate. Apart from an increase in risk of seizures and need for caution in use of stimulants, studies show that epileptiform discharges in the electroencephalogram are linked to a better response of attention deficit to methylphenidate and a higher cognitive performance. Transient cognitive impairment related to subclinical electrographic abnormalities responds to antiepileptic medication. An EEG is important in selected cases of attention deficit disorder and is useful in choice of medication, especially in children with lack of awareness and transient cognitive impairment.

Abstract
To analyze mediatory mechanisms underlying attention-deficit hyperactivity disorder (ADHD) and their association with epilepsy, the electroencephalogram (EEG) responses to various centrally applied neurotransmitter agonists were studied in spontaneously hypertensive (SH), kainate-treated (KA), and normotensive (control) rats, with chronically implanted electrodes into the frontal cortex and hippocampus and a cannula into the lateral cerebral ventricle. In SH rats, the baseline EEG showed increased delta and beta2 activity in the hippocampus and decreased alpha/beta1 activity in both brain areas. In KA rats, these delta and alpha/beta1 effects were observed 2 weeks post-kainate, while the beta2 activity increase occurred after 5 weeks in the hippocampus and, to a greater extent, 9 weeks post-injection in both brain areas. In SH rats, NMDA increased delta and decreased alpha/beta1 activity, similar to KA rats 5 weeks post-injection. In SH rats, clonidine augmented theta/beta2 increase in the cortex and alpha suppression in both brain areas, in parallel with induction of beta2 activity in the hippocampus. These beta2 effects were observed 5 and 9 weeks post-kainate. In SH rats, baclofen produced robust delta/theta enhancement and alpha/beta1 suppression in both brain areas, with additional beta2 activity increase in the hippocampus, while muscimol was ineffective in both groups of rats. In KA rats, EEG responses to GABA agonists were similar to those in control. Our results demonstrate sensitization of NMDA receptors and α2-adrenoceptors both in SH and KA rats and that of GABAb receptors specifically in SH rats.

Abstract
An adult cohort with tuberous sclerosis complex was investigated for the prevalence of sleep disturbances and the relationship with seizure variables, medication, and psychological functioning. Information on 35 adults was gathered using four questionnaires: Epworth Sleepiness Scale (ESS), Sleep and Epilepsy Questionnaire (SEQ), Sleep Diagnosis List (SDL), and Adult Self-Report Scale (ASR). In addition, clinical, genetic and electrophysiological data were collected. Of 35 respondents, 25 had a history of epilepsy. A subjective sleep disorder was found in 31% of the cohort. Insomnia scores showed a significant positive correlation with obstructive sleep apnea syndrome and restless legs syndrome scores. Significant correlations were found between daytime sleepiness and scores on depression, antisocial behavior, and use of mental health medication. A subgroup using antiepileptic medication showed high correlations between daytime sleepiness, attention deficits, and anxiety scores.

Abstract
OBJETIVO: Identificar na literatura elementos para explicar uma possível associação entre o transtorno de déficit de atenção e hiperatividade (TDAH) e a epilepsia e orientar quanto ao manejo clínico dos pacientes que compartilham esses transtornos. MÉTODOS: Realizou-se revisão da literatura dos últimos 10 anos nas bases de dados MedLine e Lilacs com a combinação dos descritores "attention deficit hyperactivity disorder", "ADHD" e "epilepsy". RESULTADOS: Sintomas de TDAH são frequentes em síndromes epilépticas idiopáticas. Vários fatores podem contribuir para a coexistência desses transtornos: 1) possibilidade de uma mesma propensão genética; 2) participação dos neurotransmissores noradrenalina e dopamina no TDAH e na modulação da excitabilidade neuronal; 3) anormalidades estruturais do cérebro evidenciadas em epilépticos portadores de TDAH; 4) influência dos efeitos crônicos das crises e das descargas epileptiformes interictais sob a atenção; 5) efeitos adversos das drogas antiepilépticas sob a cognição. CONCLUSÕES: As evidências atuais apontam que crises epilépticas e TDAH podem apresentar bases neurobiológicas comuns. Estudos que avaliam disfunções nas vias de sinalização das catecolaminas cerebrais e o papel das descargas epileptiformes interictais na geração dos sintomas são fundamentais na investigação desses mecanismos. Drogas psicoestimulantes são seguras e eficazes para o tratamento do TDAH na maioria dos portadores de epilepsia.
