BACKGROUND: Identifying important types of social support for patients with epilepsy is valuable to construct an effective system for support in daily life. However, previous studies have been inconsistent in identifying the most important types of social support for better quality of life (QOL) due to the high correlations between the social support factors. The present study employed network visualization analysis to identify the relationships between QOL and types of social support. METHODS: Two hundred and eighty-three patients with epilepsy (age range: 18 to 75 years) completed questionnaires of the Medical Outcomes Study Social Support Survey (MOS-SSS) and the Quality of Life in Epilepsy Inventory-31-Problems in the epilepsy monitoring unit at Tohoku University. The MOS-SSS was established to measure the four types of social support including emotional/informational support, tangible support, affectionate support, and positive social interaction. Our network visualization analysis represented the entire structure of the interrelationships between the four functions of social support and QOL. In addition, the relative importance of each function of social support were estimated by the centrality indices using three commonly used centrality indices: strength, betweenness, and closeness. RESULTS: The visualized network showed that positive social interaction and emotional/informational support were directly associated with QOL, whereas tangible support and affectionate support were not. Positive social interaction had the highest value for all three centrality indices and affectionate support had the second highest. Therefore, positive social interaction had the strongest connection to the other functions of support. DISCUSSION: Our network analysis and centrality indices findings showed that positive social interaction is the most important within the network of four types of social support and QOL. The emotional informational function is also important for directly improving QOL but is less related to the other functions. The affectionate function might be an indicator of whether a patient has a foundational relationship that leads to other functions of support. CONCLUSION: These results showed the importance of increasing positive social interaction in the social environment of patients with epilepsy. Therefore, practitioners need to encourage patients with epilepsy to increase their positive social interactions such as doing something enjoyable with others or someone to associate for relaxation to ensure high QOL. Connections outside the epilepsy support are important, such as having fun regardless of epilepsy, rather than only providing emotional or tangible support for epilepsy.

BACKGROUND: The COVID-19 pandemic has transformed healthcare significantly and telepsychiatry is now the primary means of treatment in some countries. AIMS: To compare the efficacy of telepsychiatry and face-to-face treatment. METHOD: A comprehensive meta-analysis comparing telepsychiatry with face-to-face treatment for psychiatric disorders. The primary outcome was the mean change in the standard symptom scale scores used for each psychiatric disorder. Secondary outcomes included all meta-analysable outcomes, such as all-cause discontinuation and safety/tolerability. RESULTS: We identified 32 studies (n = 3592 participants) across 11 mental illnesses. Disease-specific analyses showed that telepsychiatry was superior to face-to-face treatment regarding symptom improvement for depressive disorders (k = 6 studies, n = 561; standardised mean difference s.m.d. = -0.325, 95% CI -0.640 to -0.011, P = 0.043), whereas face-to-face treatment was superior to telepsychiatry for eating disorder (k = 1, n = 128; s.m.d. = 0.368, 95% CI 0.018-0.717, P = 0.039). No significant difference was seen between telepsychiatry and face-to-face treatment when all the studies/diagnoses were combined (k = 26, n = 2290; P = 0.248). Telepsychiatry had significantly fewer all-cause discontinuations than face-to-face treatment for mild cognitive impairment (k = 1, n = 61; risk ratio RR = 0.552, 95% CI 0.312-0.975, P = 0.040), whereas the opposite was seen for substance misuse (k = 1, n = 85; RR = 37.41, 95% CI 2.356-594.1, P = 0.010). No significant difference regarding all-cause discontinuation was seen between telepsychiatry and face-to-face treatment when all the studies/diagnoses were combined (k = 27, n = 3341; P = 0.564). CONCLUSIONS: Telepsychiatry achieved a symptom improvement effect for various psychiatric disorders similar to that of face-to-face treatment. However, some superiorities/inferiorities were seen across a few specific psychiatric disorders, suggesting that its efficacy may vary according to disease type.

BACKGROUND: Self-stigma is considered to have immensely negative influences on the living and psychological states in patients with epilepsy. Understanding the stigma experienced by patients with epilepsy is essential considering its negative impact on their treatment and quality of life (QOL). However, few sufficiently validated self-report instruments are available to evaluate self-stigma in patients with epilepsy. The Epilepsy Stigma Scale (ESS) is one of the most commonly used self-reported questionnaires available to evaluate self-stigma in patients with epilepsy. The present study translated the ESS into Japanese to validate the Japanese version of the ESS (ESS-J) in Japanese adults with epilepsy. METHODS: The study included 338 patients with epilepsy (166 men, aged 18-75 years) who underwent comprehensive assessment including long-term video-electroencephalography monitoring, neuroimaging studies, and neuropsychological and psychosocial assessments in the Tohoku University Hospital Epilepsy Monitoring Unit. This study consisted of two phases: (1) translation of the ESS into Japanese using the back-translation technique; and (2) statistical analysis of the ESS-J to evaluate the factor structure, reliability, and validity. RESULTS: The 2-factor model achieved acceptable fit to the data: χ2 = 161.27, df = 34, p < 0.01, comparative fit index = 0.929, root mean square error of approximation = 0.105, standardized root mean squared residual = 0.047, Akaike's information criterion = 203.27 and, Bayesian information criterion = 283.56. These two subscales were named enacted stigma and felt stigma based on the theoretical model of self-stigma. We found the ESS-J to have acceptable internal consistency as follows: enacted (7 items; α = 0.88) and felt stigma subscale (3 items; α = 0.82). The concurrent validity was confirmed by adequate correlation with other related instruments. Both enacted and felt stigma had positive and moderate correlations with depression as measured by the Neurological Disorders Depression Inventory for Epilepsy (r = 0.44, p < 0.01; r = 0.41, p < 0.01, respectively) and with anxiety as measured by the Generalized Anxiety Disorder -7 (r = 0.48, p < 0.01; r = 0.38, p < 0.01, respectively). CONCLUSION: The ESS-J demonstrated acceptable validity and reliability. The present study provided preliminary evidence about the psychometric properties of the ESS-J, indicating the reliable factorial structure, adequate internal consistency, and satisfactory construct and concurrent validity. Measurement of the two types of self-stigma may offer a useful tool for clinical interpretation of patients' psychological state throughout epilepsy care, and as one of the patient-reported outcomes in QOL research.

BACKGROUND: Acceptance of disability (AOD) is a key concept in rehabilitation psychology that enhances psychosocial adjustment of individuals with disability. However, the impact of AOD on well-being has never been examined for patients with epilepsy. The present study investigated whether AOD affects quality of life (QOL) in patients with epilepsy in the presence of other multiple aspects of epilepsy based on the biopsychosocial model. METHODS: We retrospectively reviewed 151 consecutive patients with epilepsy (77 men, aged 18-74 years) who underwent comprehensive assessment including long-term video-EEG monitoring, neuroimaging studies, and neuropsychological and psychosocial assessment in our epilepsy monitoring unit. Data were obtained from medical records and self-reported questionnaires. The outcome variable was QOL. Predictive variables included demographic characteristics, seizure-related variables (i.e., duration of epilepsy, seizure frequency, and number of antiepileptic drugs), psychological factors (i.e., AOD, depression, and self-stigma), and social factors (i.e., social support and education level). Acceptance of disability was measured by the Adaptation of Disability Scale-Revised (ADS-R), which we translated into Japanese with the original author's approval, and examined its internal consistency reliability. Data were analyzed using four hierarchical multiple regression analysis models. RESULTS: The mean ADS-R score was 80 (range 45-115). The predictors accounted for 42% of the variance in QOL (R2 = 0.45, ΔR2 = 0.42, F[8, 141] = 14.47, p = 0.00). Higher AOD (p < 0.01), higher social support (p < 0.01), and lower depression scores (p = 0.02) were found to contribute significantly to higher overall QOL. CONCLUSION: The present study revealed AOD as an important psychological concept, in addition to social support and depression as previously reported, to improve the QOL of patients with epilepsy. Acceptance of disability should be incorporated in the intervention to increase QOL of patients with epilepsy.

OBJECTIVE: Repeated routine electroencephalography (EEG) or even long-term video-EEG monitoring (VEM) does not always record interictal epileptiform discharges (IEDs) in some patients with epilepsy. The present study investigated whether focal seizures detected by VEM and focal abnormalities on neuroimaging are useful for the diagnosis of patients with focal epilepsy without IEDs. METHODS: We retrospectively reviewed 409 consecutive patients with focal epilepsy (207 men, aged 9 to 76 years) who underwent 4- or 5-day VEM, magnetic resonance imaging (MRI), and fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) for diagnosis to identify patients without IEDs. The occurrence of focal seizures during VEM and the presence of focal abnormalities on neuroimaging were investigated in those patients. The occurrence rate of seizures during VEM was investigated in patients with daily, weekly, monthly, and yearly seizure frequency based on history-taking. RESULTS: Ninety-five (23.2%) of 409 patients with focal epilepsy did not have IEDs. Fifty-five (57.9%) of the 95 patients had focal seizures during VEM. Fifty-four patients (56.8%) showed focal abnormalities compatible with seizure semiology on neuroimaging investigations. Neither seizure recordings nor neuroimaging abnormalities were seen in 16 (16.8%) of the 95 patients. The occurrence rate of seizures during VEM depended on the seizure frequency at history-taking. However, 28 (45.9%) of 61 patients with monthly and yearly seizure frequency had focal seizures during 4- or 5-day VEM with seizure induction. CONCLUSIONS: Video-EEG monitoring can detect focal seizures in patients with focal epilepsy but no IEDs. Comprehensive assessment including VEM and neuroimaging study is important for the diagnosis.

BACKGROUND: Tuberous sclerosis complex (TSC)-associated neuropsychiatric disorders (TAND) have a large impact on patients and their families. Improving intellectual ability outcomes using preventive vigabatrin (VGB) treatment has recently been reported. AIM: The aim of this study was to investigate the severity of behavioral problems and degree of distress among families of patients with TSC with and without a history of VGB treatment. METHOD: The study enrolled 21 children and adolescents who were patients with TSC from four hospitals: 14 in the VGB group and 7 in the no-VGB group. To evaluate patients' psychiatric and neurological symptoms, we used the TAND Checklist, Aberrant Behavior Checklist (ABC), Social Communication Questionnaire (SCQ), and Social Responsive Scale-2nd edition (SRS-2). RESULTS: All VGB-group patients were administered VGB after the onset of epileptic seizures. No obvious differences were observed between the VGB and no-VGB groups in behavioral problem scores on the TAND Checklist, or on the ABC, SCQ, and SRS-2 total scores. Behavioral problem scores were lower in patients with normal intelligence than in those with mild intellectual disability (ID; P = 0.042). Degrees of family distress assessed with the TAND Checklist were not correlated with the intelligence quotient/developmental quotient (IQ/DQ) or seizure frequency but were correlated with the total SRS-2 scores (P = 0.022). For several patients, there were large discrepancies between familial and physician ratings of the TAND impact score. CONCLUSION: Children and adolescents with TSC may present with significant behavioral difficulties and family distress, regardless of whether they were treated with VGB or not after the onset of seizures. Difficulties in social communication may have the strongest "TAND impact" on families.

BACKGROUND: To evaluate whether a teleconference-based lecture provides similar understanding of seizure semiology to a face-to-face lecture for physicians. METHODS: Subjects were 66 physicians consisting of adult and pediatric neurologists, neurosurgeons, psychiatrists, and general practitioners. All attended the 30-minute lecture to introduce various types of seizure semiology using video-clips by one of the authors (Yo.K.) and then joined the comprehensive case conference which discussed three cases in 1.5 h. Group A received the lecture and conference using a teleconference system (N = 43) and Group B attended in person (N = 23) for geographical reasons. After the conference, 32 subjects (23 in Group A and nine in Group B) scored their own post-lecture understanding of seizure semiology using the four-point Likert scale from 1 (not at all) to 4 (very well) as well as the estimated pre-lecture score. Data was analyzed to assess whether their understanding was improved after the lecture. RESULTS: No significant difference was found in improvement of understanding after the lecture between Group A (43%) and Group B (22%; p = 0.42). Pre-lecture score of subjects with improved understanding was significantly lower (2.3 +/- 0.2) than those without improvement (3.7 +/- 0.1) (p < 0.05). SIGNIFICANCE: Teleconference-based lectures can be a useful tool to educate seizure semiology for physicians, especially at the inexperienced level, by overcoming geographical limitations.

PURPOSE: Predictive factors of higher drug load for seizure freedom were investigated in idiopathic generalized epilepsy (IGE), focusing on the difference between juvenile myoclonic epilepsy (JME) and other types of IGE (non-JME IGE). METHODS: Twelve patients with JME and 12 patients with non-JME IGE, who achieved seizure freedom for 1 year or longer with appropriate antiepileptic drugs (AEDs) after video electroencephalography monitoring, were reviewed retrospectively. The sum of prescribed daily dose/defined daily dose ratio of all prescribed AEDs at the final visit was defined as total AED load. Patients requiring total AED load >1 were classified into the higher AED load group. Clinical background and the presence of interictal focal epileptiform abnormalities (FEAs) were compared between the higher and lower AED load groups. RESULTS: Higher AED load group of patients with JME had interictal FEAs and family history of epilepsy more frequently than the lower AED load group (p = 0.03 and p = 0.03). Similar comparison of patients with non-JME IGE showed no significant differences. CONCLUSIONS: The presence of interictal FEAs and a family history of epilepsy are significantly associated variables for higher AED load for seizure freedom in patients with JME, but not in patients with non-JME IGE.

OBJECTIVE: Intellectual disability (ID) is associated with weight gain caused by antiepileptic drugs such as valproic acid. The present study analyzed the relationship between ID and weight loss caused by topiramate (TPM). METHODS: Seventy-eight patients with epilepsy (35 women, aged 18 to 70years) were enrolled in this prospective study. Body weight was measured before and 1, 6, 12, and 18months after initiation of TPM treatment. Both patients and caregivers were provided information about TPM-related weight loss. The patients were divided into the group with no or mild ID (intelligence quotient >50) and the group with moderate to profound ID (intelligence quotient ≤50). RESULTS: Body weight of both groups significantly decreased until 6months but stabilized after 12months. Weight loss at 6, 12, and 18months was significantly greater in the group with no or mild ID than in the group with moderate to profound ID. Body weight change at 18months was correlated with intellectual levels (ß=0.274, p=0.011) and baseline body mass index (ß=-0.322, p=0.002) by multiple linear regression analysis. CONCLUSIONS: The present study suggests that the pattern of weight loss during TPM administration differs according to intellectual levels. Patients with ID maintained their body weight. Weight loss due to TPM might be weakened by caregiver control of food intake or inactivity.

Multiple chemical sensitivity (MCS) is a disorder of unknown etiology with no effective treatment. Many clinicians accept that a diagnosis of somatic symptoms disorder (SSD) is an appropriate diagnostic category for MCS. We found that administration of levetiracetam improved recurrent symptoms of MCS in a patient. A 23-year-old female presented with recurrent multiple symptoms of musculoskeletal, airway or mucous membrane, heart/chest-related, gastrointestinal, cognitive, affective, neuromuscular, head-related, and skin-related induced by exposure to diesel or gas engine exhaust, tobacco smoke, insecticide, gasoline, paint or paint thinner, cleaning products, fragrances, tar or asphalt, nail polish or hairspray, and new furnishings. Gastrointestinal, cognitive, and skin-related symptoms were precipitated by some food additives. She suffered partial seizures from the age of 17 years, and was diagnosed with right parietal lobe epilepsy. Administration of levetiracetam (250 mg/day) eliminated her MCS symptoms. Levetiracetam reduces the release of presynaptic neurotransmitter including glutamate by binding to presynaptic vesicle protein. A recent study established the presence of glutamatergic overactivation in somatization disorder, a form of SSD. Our case may indicate that a subset of patients with SSD have glutamatergic overactivation, which levetiracetam can normalize. J. Med. Invest. 64: 296-298, August, 2017.

We present a 28-year-old female patient whose epilepsy started at the age of 19. MRI showed right perisylvian polymicrogyria. She exhibited various seizure symptoms, such as somatosensory aura involving the left leg, dyscognitive seizures, and amnesic seizures. Her mother indicated that the patient sometimes had "sleep talking", which was associated with presence of epileptic seizures of the next day. Long-term video electroencephalography (EEG) revealed that her episodes of "sleep talking" were epileptic events, specifically ictal speech, originating in the right hemisphere. The present case demonstrates the importance of considering "sleep talk" as an epileptic symptom. Careful history taking is fundamental to carry patients with possibly pathological "sleep talk" to the long-term video EEG, which will contribute correct diagnosis and treatment.

In Escherichia coli, the [2Fe-2S] transcriptional factor, SoxR, functions as a sensor of oxidative stress. The transcriptional activity in SoxR is regulated by the reversible oxidation and reduction of [2Fe-2S] clusters. We previously proposed that superoxide (O2•-) has a direct role as a signal for E. coli SoxR and that the sensitivity of the E. coli SoxR response to O2•- is 10-fold higher than that of Pseudomonas aeruginosa SoxR. The difference between the two homologues reflects interspecies differences in the regulatory role of O2•- activation. To investigate the determinants of SoxR's sensitivity to O2•-, we substituted several amino acids that are not conserved among enteric bacteria SoxR homologues and investigated the interaction of SoxR with O2•- using pulse radiolysis. The substitution of E. coli SoxR Lys residues 89 and 92 with Ala residues (K89AK92A), located close to [2Fe-2S] clusters, dramatically affected this protein's reaction with O2•-. The second-order rate constant of the reaction was 3.3 × 107 M-1 s-1, which was 10 times smaller than that of wild-type SoxR. Conversely, the corresponding substitution of Ala90 with Lys in P. aeruginosa SoxR increased the rate approximately 10-fold. In contrast, introductions of the Arg127Ser128Asp129 → Leu127Gln128Ala129 substitution into E. coli SoxR, and the corresponding substitution (Leu125Gln126Ala127 → Arg125Ser126Asp127) in P. aeruginosa SoxR, did not affect the reaction rates. In addition, the Lys mutation in E. coli SoxR (K89AK92A) showed a defect in vivo transcriptional activity by measuring ß-galactosidase expression in response to paraquat. Our findings clearly support the idea Lys is critical to the response to O2•- and further transcriptional activity of SoxR.

BACKGROUND: Interictal behavioral symptoms in frontal lobe epilepsy (FLE) are variable and often difficult to discriminate from other localization-related epilepsies. METHODS AND RESULTS: We report two female patients with right FLE who exhibited fantastic confabulations. One of the patients had a 14-year history of hypermotor seizures, and the other had a 10-year history of dyscognitive seizures with automatism. Their fantastic confabulations arose in the context of moderate-to-severe cognitive impairment and of a variety of behavioral abnormalities, including emotional withdrawal and compulsive behaviors. CONCLUSION: Fantastic confabulations are rare but may be a relatively specific behavioral marker for FLE-associated psychosis.

We present a case of epilepsy with multiple types of focal seizures that were misdiagnosed as psychiatric disorders. A 20-year-old female patient presented with a variety of episodes, including loss of consciousness, deja vu, fear, delusion of possession, violent movements, and generalized convulsions. Each of these symptoms appeared in a stereotypic manner. She was initially diagnosed with a psychiatric disorder and treated with psychoactive medications, which had no effect. Long-term video electroencephalography revealed that her episodes of violent movement with impaired consciousness and secondarily generalized seizure were epileptic events originating in the right hemisphere. High-field brain magnetic resonance imaging for detecting subtle lesions revealed bilateral lesions from periventricular nodular heterotopia. Her final diagnosis was right hemispheric focal epilepsy. Carbamazepine administration was started, which successfully controlled all seizures. The present case demonstrates the pitfall of diagnosing focal epilepsy when it presents with multiple types of psychiatric aura. Epilepsy should thus be included in differential diagnoses, considering the stereotypic nature of symptoms, to avoid misdiagnosis.

A novel antiepileptic drug, levetiracetam, has been reported to cause several psychiatric adverse effects in spite of its effectiveness on epilepsy. However, a possible relationship between levetiracetam and obsessive-compulsive behavior has only been reported in a few studies with adult epilepsy patients. We treated a pediatric patient with epilepsy without past or family history of psychiatric disorder. Levetiracetam was started to control generalized tonic-clonic seizure. Two months after initiation of levetiracetam with favorable seizure control, she started to show an obsessive-compulsive behavior such as repetitive checking of her back, pants, and chair. Based on the course of its appearance, levetiracetam administration was identified as a possible cause. After termination of levetiracetam, her obsessive-compulsive behavior completely disappeared with reappearance of seizures. This case provides clear evidence that levetiracetam may cause obsessive-compulsive behavior even in a pediatric epilepsy patient without psychiatric background, possibly mediated by modulation of the glutamate system by levetiracetam.

The [2Fe-2S] transcriptional factor SoxR, a member of the MerR family, is regulated by the reversible oxidation and reduction of [2Fe-2S] clusters and functions as a sensor of oxidative stress in Escherichia coli. In the oxidized state, distortion of the target DNA promoter region initiates transcription by RNA polymerase, thereby activating transcription. The inactive reduced state of the protein has remained uncharacterized. Here, we directly observed redox-dependent conformational changes in the promoter DNA by site-specifically replacing selected adenine (A) and cytosine (C) bases in the promoter oligonucleotide with the fluorescent probes 2-aminopurine (2Ap) and pyrrolocytosine (pyrrolo-dC), respectively. Reduction of the [2Fe-2S] cluster in the SoxR-DNA complex dramatically weakened the fluorescence intensity of the 2Ap moieties incorporated into the central part of the DNA. In contrast, the fluorescence of 2Ap moieties incorporated at A in other regions and the fluorescence of pyrrolo-dC moieties in the central region of the DNA (C3 and C3') were only slightly decreased by the reduction. These results strongly suggest that the redox change causes a large conformational change within a region confined to the central A-T base pairs in the promoter region of the DNA.

The [2Fe-2S] transcriptional factor SoxR, a member of the MerR family, functions as a sensor of oxidative stress in Escherichia coli. The transcriptional activity of SoxR is regulated by the reversible oxidation and reduction of [2Fe-2S] clusters. Electrochemistry measurements on DNA-modified electrodes have shown a dramatic shift in the reduction potential of SoxR from -290 to +200 mV with the promoter DNA-bound [ Gorodetsky , A. A. , Dietrich , L. E. P. , Lee , P. E. , Demple , B. , , Newman , D. K. , and Barton , J. K. ( 2008 ) DNA binding shifts the reduction potential of the transcription factor SoxR , Proc. Natl. Acad. Sci. U.S.A. 105 , 3684 - 3689 ]. To determine the change of the SoxR reduction potential using the new condition, the one-electron oxidation-reduction properties of [2Fe-2S] cluster in SoxR were investigated in the absence and presence of the DNA. The [2Fe-2S] cluster of SoxR was completely reduced by nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome P450 reductase (CRP) in the presence of a NADPH generating system (glucose 6-dehydrogenase and glucose-6 phosphate), indicating that CRP can serve as an NADPH-dependent electron carrier for SoxR. The reduction potential of SoxR was measured from equilibrium data coupled with NADPH and CRP in the presence of electron mediators. The reduction potentials of DNA-bound and DNA-free states of SoxR were -320 and -293 mV versus NHE (normal hydrogen electrode), respectively. These results indicate that DNA binding causes a moderate shift in the reduction potential of SoxR.

PURPOSE: The purpose of this study was to assess the impact of a cognitive behavioral therapy (CBT) anxiety intervention on social phobia, social skill development, and self-concept. METHOD: Fifteen children with epilepsy and a primary anxiety disorder participated in a CBT intervention for 12 weeks plus a 3-month follow-up visit. Children were assessed at baseline, week 7, week 12, and 3 months post treatment to measure changes in social phobia using the Screen for Child Anxiety Related Emotional Disorders (SCARED). Self-concept was also assessed by using the Piers-Harris Children's Self-Concept Scale II (Piers-Harris 2). RESULTS: There was a significant reduction in symptoms of social phobia and improved self-concept at the end of the 12-week intervention and at the 3 month follow-up. Repeated measures ANOVA's of child ratings revealed significant change over time on the SCARED-Social Phobia/Social Anxiety subscale score (p=0.024). In terms of self-concept, significant change over time was detected on the Piers-Harris 2-Total score (p=0.015) and several subscale scores of Piers-Harris 2, including: Physical Appearance and Attributes (p=0.016), Freedom from Anxiety (p=0.005), and Popularity (p=0.003). CONCLUSION: This pilot investigation utilized an evidenced based CBT intervention to reduce symptoms of social phobia, which in turn provided a vehicle to address specific social skills improving self-concept in children with epilepsy.
