Screening for depression in patients with epilepsy: What are the benefits for physicians and patients in the real-life setting. Epilepsia 2024. [PMID: 39140982 DOI: 10.1111/epi.18089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 07/18/2024] [Accepted: 07/26/2024] [Indexed: 08/15/2024]
Abstract
OBJECTIVE Screening for depression in people with epilepsy (PWE) is highly recommended in order to avoid underdiagnosis, misdiagnosis, or delayed diagnosis of this highly impacting comorbidity. Here we evaluated the impact of reporting and suggesting depression via the Beck Depression Inventory (BDI) on medical decision-making, and thereby the value of a depression screening for good medical practice. METHODS Of 445 BDI data sets, PWE with scores indicating moderate (BDI 19-29) to severe depressive disorder (BDI >29) were extracted and clinical reports were retrospectively reviewed regarding decisions on antidepressants, anti-seizure medications (ASMs), and non-pharmaceutical interventions. RESULTS Sixty-four PWE (14%; 56% female; mean age 39.7 years) showed elevated BDI scores, with 40 (63%) categorized as moderate depression and 24 (37%) as severe depression. Thirty-nine percent of PWE already had a pre-existing diagnosis of depression and 53% left the clinic with the diagnosis of depression, half of them with antidepressants. High depression scores were associated with any intervention in 53%, interventions with potentially mood affecting ASM in 19%, treatment with antidepressants in 11%, and non-pharmaceutical interventions in 41%. Non-pharmaceutical interventions were related to BDI scores. Changes of potentially mood-affecting ASMs were more frequent in PWE with moderate scores, and introduction of antidepressants appeared as a trend related to higher depression scores. SIGNIFICANCE The finding of an only weak relation between high depression scores, diagnoses of depression, and treatment consequences questions the diagnosis and treatment pathway and the clinical value of the BDI screening in PWE. Prospective standard procedures need to be established for depression diagnosis and treatment including follow-up evaluations of the validity of the diagnosis and effectiveness of the decisions taken.

Abstract
People with intellectual disabilities (PwID) have a bidirectional relationship with epilepsy. Nearly 25% of PwID have seizures and 30% people with epilepsy are thought to have a significant intellectual impairment. Furthermore, 70% of PwID are thought to have treatment-resistant epilepsy. In the United Kingdom, antiseizure medications (ASMs) are the second most widely prescribed psychotropic agent for PwID. However, it is unclear what the current evidence and patterns is on current prescribing of ASMs, including when and how a case is made to withdraw them. A narrative review along with an analysis of large-scale NHS Digital published data (2015-2020) on several aspects of ASM prescribing by general practices for PwID was undertaken. The review results and data analysis are consolidated and presented as 11 themes to provide a comprehensive overview of the study topic. Recent studies estimate that one-third and one-fifth of PwID are prescribed ASMs. A history of epilepsy is seen as the primary prescribing reason; however, often it is a legacy, and the indication is no longer clear. The proportion receiving ASMs continues to rise with age. This pattern of use does not correlate well with seizure onset. There are limited data on de-prescribing ASMs in PwID. The study population heterogenicity, associated polypharmacy, multimorbidity and higher sudden unexpected death in epilepsy risks are outlined. Suggestions are made from available evidence for improving prescribing practices for PwID and seizures, and key areas for further research in this complex clinical area are outlined.

Abstract
Autism spectrum disorder (ASD) with regression (ASD-R) involves the loss of previously attained developmental milestones, typically during the first or second year of life. As children age, it is not uncommon for them to develop comorbid conditions such as aggressive behaviors or epilepsy, which can inhibit habilitation in language and social function. In this paper, we hypothesize that aggressive behaviors and epilepsy more commonly develop in patients with ASD-R than in those without a history of regression (ASD-NR). We conducted a retrospective review of non-syndromic patients with ASD over 12 years of age and compared the rates of epilepsy and aggression between ASD-R and ASD-NR patients. Patients with ASD-R, as compared to ASD-NR patients, demonstrated non-significantly higher rates of epilepsy (51.8% vs. 38.1%, p = 0.1335) and aggressive behaviors (73.2% vs. 57.1%, p = 0.0673) when evaluated separately. The rates for combined epilepsy and aggression, however, were statistically significant when comparing ASD-R versus ASD patients (44.5% vs. 23.8%, p = 0.0163). These results suggest that epilepsy with aggression is more common in ASD-R as compared to ASD-NR patients. When considering the impact of epilepsy and aggression on quality of life, these co-morbidities effectively cause a second regression in patients who experienced an earlier regression as toddlers. A larger, prospective trial is recommended to confirm these associations and further define the timeline in which these characteristics develop from early childhood to adolescence.

Abstract
Antiseizure medications (ASMs) are the second most widely prescribed psychotropic for people with intellectual disabilities in England. Multiple psychotropic prescribing is prevalent in almost half of people with intellectual disabilities on ASMs. This analysis identifies limited evidence of ASM benefit in challenging behaviour management and suggests improvements needed to inform clinical practice.

Abstract
OBJECTIVE This study presents the proportion of adults with intellectual disability using psychotropic medications including antipsychotics, antidepressants, anxiolytics, hypnotics and sedatives, and psychostimulants. METHODS A search was performed in PubMed, Embase, PsycINFO, Web of Science, and Scopus up to 31 December 2021. Articles were included if they reported the proportion of adults with intellectual disability using psychotropic medications. Frequency of use was estimated using a random effects meta-analysis. Meta-regression analysis was used to assess the association between study-level characteristics and variability in estimates, when heterogeneity was considerable. RESULTS Twenty-four articles were included in pooled analysis. The pooled prevalence of psychotropic medications was 41% (95% confidence interval: 35-46%). Pooled prevalences of subclasses were as follows: antipsychotics 31% (27-35%), antidepressants 14% (9-19%), anxiolytics 9% (4-15%), hypnotics/sedatives 5% (2-8%), and psychostimulants 1% (1-2%). Heterogeneity was considerable between studies, except for psychostimulants. There was no significant association between assessed characteristics and variability in prevalence estimates. CONCLUSION Two-fifths of adults with intellectual disability were prescribed psychotropic medications. Antipsychotics and antidepressants were used by one-third and one-seventh of adults, respectively. There was considerable variability between studies, and further investigation is required to determine the source of variability. More studies are needed to better characterise prescribed psychotropic medications, including effectiveness and adverse effects, to ensure appropriate use of these drugs.

Abstract
Background Different epidemiologic aspects of drug-induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in children are scarce. Aim To compare the clinical and epidemiological features of patients with drug-induced SJS and TEN in children and adults. Method This retrospective study was conducted at two academic referral centers (Isfahan, Iran) over 5 years. SJS and TEN were clinically diagnosed and confirmed by skin biopsy as needed. Results One hundred one patients (31 children and 70 adults) with a female to male ratio of 1.1 : 1 was identified in the present study. SJS was more commonly diagnosed in both pediatric and adult patients. The most frequent reason for drug administration identified was the infection (45.2%) and seizure (45.2%) in children and infection (34.3%) and psychiatry disorder (27.1%) in adults (P = 0.001). The most common culprit drugs in the pediatric were phenobarbital (9/31), cotrimoxazole (4/31), and amoxicillin (4/31); however, in the adult group, the most common drugs were carbamazepine (11/70) and lamotrigine (9/70). Fever was significantly more common in adults (44.3%) compared to pediatric patients (22.6%) (P = 0.03). Multiple logistic regression models showed that pediatric patients had significantly lower odds of hospitalization (OR [odds ratio]: 0.14; 95% CI 0.02, 0.67). In addition, patients with SCORTEN 1 had significantly higher odds of hospitalization (OR: 6.3; 95% CI: 1.68, 23.79) compared to patients with SCORTEN 0. Conclusions The present study showed several differences between the pediatric and adult patients with SJS and TEN, including the reason for drug administration, culprit drugs, length of hospital stay, presence of fever, and final diagnosis of disease.

The relationship between antiepileptic drug load and challenging behaviors in older adults with intellectual disability and epilepsy. Epilepsy Behav 2021; 122:108191.

Abstract
Antiepileptic drugs (AEDs) may affect mood and behavior in people with epilepsy and intellectual disability. A high AED load, derived from AED polytherapy and/or high doses of AEDs, has been suggested to be a risk factor for behavioral side effects. Data were drawn from Wave 3 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA). The Behavior Problems Inventory Short Form (BPI-S) was used to assess challenging behaviors. AED load was calculated and median AED loads obtained. Non-parametric tests and binary logistic regression were performed to determine the relationship between AED load and challenging behaviors. Of participants with a reported diagnosis of epilepsy who were taking a regular AED and had completed BPI-S (n = 142), 62.7% (n = 89) exhibited challenging behaviors. Challenging behavior was found to be more prevalent in those with more severe levels of intellectual disability (p < 0.001). Aggressive/destructive behavior and stereotyped behavior were significantly more likely in participants living in residential/campus settings. For participants with a severe/profound intellectual disability, a significantly higher median AED load was found for participants exhibiting aggressive/destructive behavior and self-injurious behavior (SIB) compared to participants not exhibiting these behaviors, indicating a high AED load may contribute to some behavioral problems in this population group. However, many factors can influence behavioral outcomes, creating difficulties in determining those that are associated and the nature of the association. Careful monitoring of AED load, together with increased vigilance for breakthrough behavioral issues is essential for dealing with these complex cases. Larger studies are needed to account for the potential confounding factors.

Abstract
Psychogenic non-epileptic seizures (PNES) superficially resemble epileptic seizures, but are not associated with abnormal electrical activity in the brain. PNES are a heterogeneous entity and while there is increasing interest in the characterisation of PNES sub-groups, little is known about individuals with PNES who have an intellectual disability (ID). ID is a lifelong condition characterised by significant limitations in cognitive, social and practical skills. ID (commonly with comorbid epilepsy) has been identified as a risk factor for developing PNES. However, people with ID are often excluded from research in PNES. This has unfortunately resulted in a lack of evidence to help inform practice and policy for this population. This narrative review synthesises the currently available evidence in terms of the epidemiology, demographic and clinical profile of adults with PNES and ID. There is a particular focus on demographics, aetiological factors, PNES characteristics, diagnosis and treatment of the condition in this population. Throughout this article, we critique the existing evidence, discuss implications for clinical practice and highlight the need for further research and enquiry. What emerges from the evidence is that, even within the sub-group of those with ID, PNES are a heterogeneous condition. Individuals with ID and PNES are likely to present with diverse and complex needs requiring multidisciplinary care. This review is aimed at the broad range of healthcare professionals who may encounter this group. We hope that it will stimulate further discussion and research initiatives.

Abstract
N-(2-hydroxyphenyl)-2-propylpentamide (HO-AAVPA) is a novel arylamide derivative of valproic acid (VPA) designed in silico, with better antioxidant and antiproliferative effect on cancer cell lines than VPA. This study was aimed to evaluate the anticonvulsant activity, the toxicity and teratogenicity produced in HO-AAVPA-treated CD1 mice using VPA as positive control. With the maximal electroshock (MES)- and pentylenetetrazole (PTZ)-induced seizure models, HO-AAVPA reduced the time of hind limb extension, stupor and recovery, the number of clonic and tonic seizures and the mortality rate in a dose-dependent manner, obtaining an ED50 of 370 and 348 mg/kg for MES and PTZ, respectively. On the rotarod test, mice administered with 600 mg/kg HO-AAVPA manifested reduced locomotor activity (2.78%); while HO-AAVPA at 300 mg/kg and VPA at 500 mg/kg gave a similar outcome (∼60%). The LD50 of 936.80 mg/kg herein found for HO-AAVPA reflects moderate toxicity. Concerning teratogenicity, the administration of HO-AAVPA to pregnant females at 300 and 600 mg/kg on gestation day (GD) 8.5 generated less visceral and skeletal alterations in the fetuses, as well as, minor rate of modifications in the expression pattern of the neuronal marker Tuj1 and endothelial marker PECAM1 in embryos, that those induced by VPA administration. Altered embryonic development occurred with less frequency and severity with HO-AAVPA at 600 mg/kg than VPA at 500 mg/kg. In conclusion, the protective effect against convulsions provided by HO-AAVPA was comparable to that of VPA in the MES and PZT seizure models, showed lower toxicity and less damage to embryonic and fetal development.

Abstract
Peripheral nerve injury is a complex condition with a variety of signs and symptoms such as numbness, tingling, jabbing, throbbing, burning or sharp pain. Peripheral nerves are fragile in nature and can easily get damaged due to acute compression or trauma which may lead to the sensory and motor functions deficits and even lifelong disability. After lesion, the neuronal cell body becomes disconnected from the axon's distal portion to the injury site leading to the axonal degeneration and dismantlement of neuromuscular junctions of targeted muscles. In spite of extensive research on this aspect, complete functional recovery still remains a challenge to be resolved. This review highlights detailed pathophysiological events after an injury to a peripheral nerve and the associated factors that can either hinder or promote the regenerative machinery. In addition, it throws light on the available therapeutic strategies including supporting therapies, surgical and non-surgical interventions to ameliorate the axonal regeneration, neuronal survival, and reinnervation of peripheral targets. Despite the availability of various treatment options, we are still lacking the optimal treatments for a perfect and complete functional regain. The need for the present age is to discover or design such potent compounds that would be able to execute the complete functional retrieval. In this regard, plant-derived compounds are getting more attention and several recent reports validate their remedial effects. A plethora of plants and plant-derived phytochemicals have been suggested with curative effects against a number of diseases in general and neuronal injury in particular. They can be a ray of hope for the suffering individuals.

Abstract
Focal-onset seizures are among the most common forms of seizures in children and adolescents and can be caused by a wide diversity of acquired or genetic etiologies. Despite the increasing array of antiseizure drugs available, treatment of focal-onset seizures in this population remains problematic, with as many as one-third of children having seizures refractory to medications. This review discusses contemporary concepts in focal seizure classification and pathophysiology and describes the antiseizure medications most commonly chosen for this age group. As antiseizure drug efficacy is comparable in children and adults, here we focus on pharmacokinetic aspects, drug-drug interactions, and side effect profiles. Finally, we provide some suggestions for choosing the optimal medication for the appropriate patient.

Abstract
OBJECTIVE Depression and anxiety symptoms are common among patients with epilepsy, but are relatively under-researched in patients with both epilepsy and intellectual disability (ID). The aim was to investigate whether epilepsy and ID characteristics are associated with mood, anxiety, and quality of life. MATERIALS AND METHODS Adult patients with epilepsy and ID who rely on tertiary epilepsy care were included (N = 189). Mood, anxiety, and quality of life were assessed by standardized questionnaires. Epilepsy and ID characteristics were retrieved from patient charts or determined by psychometric instruments. RESULTS Elevated levels of depressive and anxiety symptoms were present in 21.7% and 12.7%, respectively. Anxiety was significantly associated with a focal epilepsy type and ID domain discrepancy (substantial difference between two domains of adaptive behavior), but was negatively related to seizure frequency and drug load of mood-stabilizing antiepileptic drugs. Depressive symptoms were not significantly related to epilepsy characteristics, but a severe ID and ID domain discrepancy was associated with more depressive symptoms. Quality of life was significantly worse in those with multiple seizure types and ID domain discrepancy. CONCLUSION Whereas anxiety and quality of life are associated with individual epilepsy characteristics, this could not be confirmed for depressive symptoms in patients with epilepsy and ID, despite its high prevalence.

Abstract
PURPOSE The purpose of the present study was to compare depression and QoL between patients with epilepsy and healthy controls, evaluating potentially related factors to depression and QoL in patients with epilepsy in Northwest Greece. METHODS A case study was conducted in adult patients with epilepsy followed up at the University Hospital of Ioannina and in healthy controls. The Patient Health Questionnaire (PHQ-9) for depression's severity evaluation, the WHOQOL-BREF questionnaire for the QoL estimation and the Adverse Event Profile (AEP) questionnaire for the Antiepileptic Drugs (AEDs) adverse effects assessment were used. RESULTS Seventy patients with epilepsy and 70 controls were recruited. The PHQ-9 score was higher in patients compared to controls and slightly higher than reported in patients with epilepsy. PHQ-9 was significantly associated with the AEP score. Our patients had a poorer QoL compared to controls. The level of education, the AEP and the PHQ-9 scores were associated to QoL, the last two being the most powerful predictors of QoL. CONCLUSION Patients with epilepsy in Northwest Greece had higher rates of depression than reported in patients with epilepsy and poorer QoL compared to controls. The adverse effects of AEDs were related to depression in our study, while the adverse effects of AEDs and depression were more powerful predictors of QoL compared to demographics and other characteristics of epilepsy.

Abstract
Mood dysregulation is a common feature in the psychopathology of people with intellectual disability (ID) and co-occurring behavioral/psychiatric disorders. It can present with a host of dangerous behaviors, including aggression, self-injury, and property damage. There are special techniques that are used to assess these behaviors in people with ID, that can eventually inform an appropriate approach to pharmacologic and nonpharmacologic treatment. Two case studies are presented that illustrate the elements in the assessment and treatment of mood dysregulation in ID.

Abstract
It is known that for all adults, prevalence of potentially inappropriate prescribing (PIP) and polypharmacy increases with advancing age and morbidity. This has been associated with adverse drug reactions and poor outcomes. As a result, screening tools have been developed to identify PIP and to improve prescribing and health outcomes. A growing body of evidence supports the fact that there are even greater concerns among older adults with intellectual disability (ID) who are living longer than before but still have premature mortality and poorer health outcomes compared with the general population. They have different patterns of multimorbidity, with higher rates of epilepsy and mental health conditions. Polypharmacy is prevalent and some prescribing practices may be inappropriate. High exposure to anticholinergic and sedative medicines has additional adverse effects on quality of life. There may also be underutilization of clinically needed therapies. There has been substantial controversy internationally relating to extensive use of psychotropic medicines, particularly off-label use for challenging behaviours. Despite the mounting evidence and concerns about the impact of PIP on quality of life, health and safety for people with ID, appropriate methods to measure PIP are lacking, which represents an important gap in the research literature. Differences in morbidity and medicines use patterns in this population mean instruments used to identify inappropriate medicines in the older population are not suitable. In this perspective article we outline the specific health and medicinal needs for people with ID, the prevalence of polypharmacy and presentation of chronic health conditions in older adults with ID. We provide an overview of the psychotropic medicine classes most frequently used in people with ID which carry substantial risk. We highlight studies to date that have attempted to assess PIP and present research priorities to improve prescribing, health outcomes and quality of life for people with ID.

Challenging behavior in adults with epilepsy and intellectual disability: An analysis of epilepsy characteristics. Epilepsy Behav 2018; 86:72-78.

Abstract
PURPOSE The study aimed to describe the frequency and severity of self-injurious, stereotyped, and aggressive/destructive behavior in adults with both epilepsy and intellectual disability (ID) who reside at a tertiary epilepsy center and to investigate the associations between challenging behavior and epilepsy and ID characteristics. METHOD The frequency and severity of self-injurious, (motoric) stereotyped, and aggressive/destructive behavior among 189 patients was assessed using the Behavior Problem Inventory. Comparisons were made with an adult reference population with ID, based on gender, to determine whether the behavior was clinically deviant. Epilepsy characteristics, including age at onset, epilepsy type, seizure types, seizure frequency, and use of antiepileptic drugs (AEDs), were retrieved from patient files. The level of ID was classified using the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) and an ID domain discrepancy was allocated if there was a substantial difference between two domains of adaptive behavior within a subject. RESULTS Self-injurious behavior was present in 35% of subjects, stereotyped behavior in 60%, and aggressive/destructive behavior in 63%. The behavior exceeded clinical norms in 7%, 18%, and 12%, respectively. Aggression was the behavior evaluated most often as being problematic, despite its reported frequency being the lowest. When adjusting for level of ID and use of psychotropic medication, logistic regression analyses showed that self-injurious behavior was significantly associated with a lower number of AEDs (odds ratio (OR) = 0.4); that stereotyped behavior was significantly associated with a higher number of seizure types (OR = 1.4) and a lower number of AEDs (OR = 0.4); and that aggression was significantly associated with the presence of an ID domain discrepancy (OR = 3.1). CONCLUSION Challenging behavior is a serious issue among adults with epilepsy and ID. Although some of the epilepsy and ID characteristics seemed to contribute independently to these types of challenging behavior, the effects of epilepsy-related characteristics are modest when compared with ID.

Prevalence and patterns of anti-epileptic medication prescribing in the treatment of epilepsy in older adults with intellectual disabilities. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2018; 62:245-261. [PMID: 29314463 DOI: 10.1111/jir.12461] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Revised: 09/28/2017] [Accepted: 11/29/2017] [Indexed: 06/07/2023]
Abstract
BACKGROUND The prevalence of epilepsy is higher in people with intellectual disability (ID) and increases with the degree of ID. Although life expectancy for people with ID is increasing, people with ID coexisting with epilepsy have a higher mortality rate, particularly those who had recent seizures. There have been few observational studies of the prevalence and patterns of anti-epileptic prescribing among older people with ID and epilepsy. The aim of this study was to investigate prevalence and patterns of anti-epileptic prescribing in the treatment of epilepsy in a representative population of older people with ID and epilepsy. METHODS This was an observational cross-sectional study from wave 1 (2009/2010) of Intellectual Disability Supplement to the Irish Longitudinal Study on Aging, a nationally representative sample of 753 persons with ID aged between 41 and 90 years. Participants and/or proxies recorded medicines used on a regular basis and reported doctor's diagnosis of epilepsy; medication data were available for 736 (98%). Prescribing of anti-epileptic drugs (AEDs) for epilepsy in those with a doctor's diagnosis of epilepsy (N = 205) was the primary exposure of interest for this study. Participant exposure to these AEDs was then categorised into AED monotherapy and polytherapy. Participants/carers reported seizure frequency, when epilepsy was last reviewed and which practitioner reviewed epilepsy. In addition, medications that may lower the seizure threshold that were listed in the Maudsley prescribing guidelines in psychiatry were examined. RESULTS Of the 736 participants with reported medicines use, 38.9% (n = 287) were exposed to AEDs, and 30.6% (225) had a doctor's diagnosis of epilepsy. Of those with epilepsy (n = 225), 90.9% (n = 205) reported concurrent use of AEDs and epilepsy. Of these 205 participants, 50.3% (n = 103) were exposed to AED polytherapy, and 63 different polytherapy regimes were reported. The most frequently reported AEDs were valproic acid (n = 100, 48.7%), carbamazepine (n = 89, 46.3%) and lamotrigine (n = 57, 27.8%). In total, 13.7% had a concurrent psychotropic, which should be avoided in epilepsy, and 32.6% had a psychotropic where caution is required. Antipsychotics with potential epileptogenic potential accounted for 80% of these medications. Of those with AED polytherapy (n = 103), 29.5% (28) reported being seizure free for the previous 2 years. CONCLUSIONS Prevalence of epilepsy was high among older people with ID, and half were exposed to two or more AEDs. Despite the use of AED therapy, over half had seizures in the previous 2 years. As the primary goals of optimal AED treatment are to achieve seizure freedom without unacceptable adverse effects, this was not achievable for many older patients with ID and epilepsy. Our findings indicated that people with ID and epilepsy were often exposed to psychotropic medications that may lower the seizure threshold. Regular review of epilepsy and medicines (including medicines that may interact with AEDs or lower the seizure threshold) by multidisciplinary teams working to agreed standards may improve quality of prescribing. Improved exchange of information and coordination of care between specialists and primary care practitioners in line with expert consensus recommendations could bring substantial benefit.

Abstract
INTRODUCTION Autism and behavioral characteristics in adults with Dravet syndrome (DS) have rarely been systematically studied. METHOD Three scales were used to assess the outcomes of DS in adulthood in terms of autism and behavior. All the adult patients with DS, nine male and four female, aged between 18 and 60 years, living at the Epilepsy Center Kempenhaeghe in The Netherlands were included in the study. In addition, the past medical history of each patient was systematically screened for diagnoses like autism, Pervasive Development Disorder-Not Otherwise Specified (PDD-NOS), autism spectrum disorder (ASD), hyperactivity, Attention Deficit Hyperactivity Disorder (ADHD), and self-mutilation. Information concerning past and current use of psychoactive drugs was also evaluated. RESULTS Eight patients (61.5%) were classified as having autism spectrum disorder (ASD) according to the AVZ-R or according to the medical record. Self-mutilation was seen in four patients (30.8%), hyperactivity in none. Three patients (23.1%) currently used psychoactive drugs. CONCLUSION Autism spectrum disorders persist in adult patients with DS, while certain characteristics associated with behavioral problems, such as hyperactivity or use of psychoactive medication, seem to be less prominent than in childhood.

Abstract
This study aims to examine trends in outpatient psychotropic drug use among people with intellectual disabilities in Taiwan. The NHI outpatient medication records between January 1, 1997 and December 31, 2007 for people with intellectual disabilities were analyzed to observe the percent change, prevalence and prescription trends in psychotropic drugs. The overall prevalence of psychotropic medication increased from 17.82% to 23.22% during the study period. Results from stepwise logistic analysis demonstrated that females, the elderly, and individuals suffering from catastrophic disease were more prone to receive psychotropic drugs and that those with mild intellectual disability were less likely to receive psychotropic drugs. The percentage change in prescription rates of antipsychotics, hypnotics/sedatives, and antidepressants were 85.30%, 127.25%, and 167.50%, respectively, and the trends were statistically significant (p<0.05). Taiwan's NHI program and off-label use of psychotropic drugs might have attributed to this trend.

Abstract
The Matson Evaluation of Drug Side Effects (MEDS) is currently the best established and most researched measure of drug side effects in the intellectual disability (ID) literature. Initial research was conducted on its psychometric properties such as reliability and validity. More recent research studies have used the measure to determine the interactive effects of severity of drug side effects on adaptive and social behaviors as well as symptoms of commonly medicated psychiatric conditions among persons with ID. Most recently the MEDS has been used to study potential risk factors of psychotropic drugs. The present study was written to review the current status of MEDS research in the broader context of psychotropic drug side effect research in general.

Abstract
BACKGROUND Previous reports have suggested that there may be gene × gender interaction for bipolar disorder (BD)-associated genes/loci at 22q11-13. This study aimed to investigate the associations of SEZ6L genetic variants with bipolar disorder I (BD-I) and to examine gender-specific genetic associations. METHODS 605 BD-I Caucasian cases and 1034 controls were selected from the publicly available data of the Whole Genome Association Study of BD. To increase power, an additional 362 Caucasian controls were added to this study from the Genome-Wide Association Study of Schizophrenia. In total, 605 BD-I cases and 1396 controls (934 males and 1067 females) were available for genetic association analysis of 118 SNPs within the SEZ6L gene using PLINK software. RESULTS 16 SNPs showed significant gene x gender interactions influencing BD-I (P<0.01). In addition, significant differences in the distribution of the alleles for these 16 SNPs were observed between the female BD-I patients and healthy controls (P<0.015) but no significant associations were found for the male sample (P>0.05). The SNP rs4822691 showed the strongest association with BD-I in the female sample (P=2.18 × 10(-4)) and the strongest gene × gender interaction in influencing BD-I (P=9.16 × 10(-5)). LIMITATIONS The findings of this study need to be replicated in independent samples. CONCLUSIONS This is the first demonstration that genetic variants in the SEZ6L gene are associated with BD-I in female patients and provides additional compelling evidence for genetic variation at 22q11-13 that influences BD-I risk. The present findings highlight the gene x gender interactions modifying BD-I susceptibility.

Abstract
Histone deacetylases (HDACs) function in a wide range of molecular processes, including gene expression, and are of significant interest as therapeutic targets. Although their native complexes, subcellular localization, and recruitment mechanisms to chromatin have been extensively studied, much less is known about whether the enzymatic activity of non-sirtuin HDACs can be regulated by natural metabolites. Here, we show that several coenzyme A (CoA) derivatives, such as acetyl-CoA, butyryl-CoA, HMG-CoA, and malonyl-CoA, as well as NADPH but not NADP(+), NADH, or NAD(+), act as allosteric activators of recombinant HDAC1 and HDAC2 in vitro following a mixed activation kinetic. In contrast, free CoA, like unconjugated butyrate, inhibits HDAC activity in vitro. Analysis of a large number of engineered HDAC1 mutants suggests that the HDAC activity can potentially be decoupled from "activatability" by the CoA derivatives. In vivo, pharmacological inhibition of glucose-6-phosphate dehydrogenase (G6PD) to decrease NADPH levels led to significant increases in global levels of histone H3 and H4 acetylation. The similarity in structures of the identified metabolites and the exquisite selectivity of NADPH over NADP(+), NADH, and NAD(+) as an HDAC activator reveal a previously unrecognized biochemical feature of the HDAC proteins with important consequences for regulation of histone acetylation as well as the development of more specific and potent HDAC inhibitors.
