Association between cognitive capacity and metabolic indices in patients with neuropsychiatric disorders.

BACKGROUND: Although previous studies suggested the relationship between metabolic indices and cognitive capacity, results have been conflicting. The prevalence of metabolic and cognitive disorders is high in patients with neuropsychiatric disorders. We aimed to assess the relationship between laboratory metabolic indices and specific areas of cognitive capacity. MATERIALS AND METHODS: This was a retrospective review of the medical records of 423 from 452 patients with neuropsychiatric disorders who were admitted to the neuropsychiatry unit, Ayatollah Kashani Hospital, Isfahan, Iran, from September 1, 2018, to September 30, 2022. We extracted demographic factors, laboratory metabolic indices, and scores of the Neuropsychiatry Unit Cognitive Assessment tool (NUCOG). We utilized a generalized linear model (GLM) to demonstrate the effect of metabolic indices on the risk of reduction in cognitive domains. Due to the presence of missing data in the metabolic indices, we used the multiple imputation method. RESULTS: The regression coefficient of NUCOG total score and subscale scores for metabolic indices using GLM after multiple imputation method demonstrated that among the metabolic indicators, fasting blood sugar (FBS) had the reverse relationship with the total score of NUCOG (ß = -.05). Among the NUCOG subscales, executive functioning had the strongest relationship with FBS (ß = -.01). Also, there was a negative relationship between patients' age and the total score of NUCOG (ß = -.38). Educational level had a positive relationship with the total NUCOG score (ß =10.2). CONCLUSIONS: The main metabolic factors that might reduce cognitive capacity were higher FBS.

The effect of educational intervention based on the Progressively Lowered Stress Threshold extended model on the process of caregiving for people with dementia.

BACKGROUND: This study examined the impacts of an educational intervention based on the Progressively Lowered Stress Threshold (PLST) extended model on caregiving for people with dementia (PWD). METHOD: This study was conducted in Isfahan, Iran, from May 2016 to June 2018, with 38 caregivers of PWD as participants assigned to an intervention group. Data were collected using a multi-sectional, researcher-developed questionnaire that recorded the demographic characteristics, and measured the dementia-related knowledge and caregiving practices of the participants. The questionnaire and an educational program were designed in three parts according to the educational needs of caregivers to enhance their practice, skills, and ability to handle challenging behaviours in PWD. The questionnaire's face validity was confirmed by expert review, and its reliability was assessed with Cronbach's alpha coefficient (knowledge section, 0.838; practice section, 0.802). The sampling method used was convenience sampling, and none of the caregivers refused to receive the educational content. Therefore, the evaluation of the program lacks a randomized controlled group. To tailor the intervention program to the participants' needs, the educational content was based on the PLST extended model. RESULTS: The mean scores for knowledge and practice increased following the intervention (P < 0.05). An educational intervention, using the PLST extended care model, thus produced positive impacts in improving the knowledge and practice of caregivers of PWD. CONCLUSION: Educating caregivers with the PLST extended model, with a specific focus on the cultural and religious backgrounds of societies, is recommended.

Assessment of intelligence quotient in patients with neuromyelitis optica spectrum disease and multiple sclerosis.

BACKGROUND: Cognitive impairment is common in people living with neuromyelitis optica spectrum disease (NMOSD) and multiple sclerosis (MS). However, there is little published data on intelligence quotient (IQ) in NMOSD patients. Therefore, we performed the present study to compare IQ scores across NMOSD, MS, and control groups. METHOD: In this cross-sectional study, 49 NMOSD (30 with positive aquaporin4 antibody), 41 MS, and 20 control individuals were recruited. The IQ score for each person was measured using Wechsler Adult Intelligence Scale-Revised (WAIS-R). Participants were reported on eleven scores of subsets, verbal IQ (VIQ), performance IQ (PIQ), and full score IQ (FSIQ). RESULT: The scores of FSIQ, VIQ, PIQ, vocabulary, similarities, and digit-symbol in NMOSD and MS individuals were lower than the control group. Relative to control, NMOSD patients reported a lower score of information. We found no difference between NMOSD and MS groups, except in vocabulary and similarities. No significant difference between seropositive and seronegative NMOSD groups was observed except for the information and block design. In NMOSD group, a greater EDSS score was associated with decreased scores of FSIQ, VIQ, and PIQ. Being employed and being married were associated with greater scores of VIQ and PIQ, respectively. In both NMOSD and MS groups, advanced education was associated with increased scores of FSIQ and VIQ. CONCLUSION: Our study showed decreased IQ scores in NMOSD and MS. Further studies are required to examine intellectual quotient in people with NMOSD and MS.

Relationship between cognitive profile and neuroradiographic parameters in patients with idiopathic normal pressure hydrocephalus.

Background: Normal pressure hydrocephalus (NPH) is a reversible type of dementia, which affects 0.2 to 5.9 percent of elders. It manifests with triad of gait disturbances, urinary incontinence, and cognitive decline. In this study, association between cognitive and neuroradiographic parameters of idiopathic NPH (iNPH) was appraised to find out possible biomarkers for preventive intervention. Methods: In a cross-sectional study, 16 patients with iNPH were evaluated for third and fourth ventricle diameter, diameter of temporal horn of lateral ventricle, Evans index (EI), callosal angle (CA), callosal bowing, and ballooning of frontal horn. The Neuropsychiatry Unit Cognitive Assessment Tool (NUCOG) was used to take cognitive profile. Relation between brain magnetic resonance imaging (MRI) indices and cognitive domains was extracted, using generalized linear model (GLM). Results: Patients with mild callosal bowing had better function in memory (P = 0.050) and language (P = 0.001) than those with moderate to severe callosal bowing. Negative or mild ballooning of frontal horn was also associated with higher scores in memory (P = 0.010), executive function (EF) (P = 0.029), and language (P = 0.036) than moderate to severe ballooning of frontal horn. Increased 3rd ventricle diameter was associated with decline in total cognition (P = 0.008), memory (P = 0.019), EF (P = 0.012), and language (P = 0.001). Relation between other radiographic indices and cognitive function was not significant. Conclusion: Third ventricular diameter, rounding of frontal horn of lateral ventricle, and callosal bowing are more accurate neuroradiographic parameters to predict cognitive decline in iNPH.

Presurgical Language Mapping in Patients With Intractable Epilepsy: A Review Study.

INTRODUCTION: about 20% to 30% of patients with epilepsy are diagnosed with drug-resistant epilepsy and one third of these are candidates for epilepsy surgery. Surgical resection of the epileptogenic tissue is a well-established method for treating patients with intractable focal epilepsy. Determining language laterality and locality is an important part of a comprehensive epilepsy program before surgery. Functional Magnetic Resonance Imaging (fMRI) has been increasingly employed as a non-invasive alternative method for the Wada test and cortical stimulation. Sensitive and accurate language tasks are essential for any reliable fMRI mapping. METHODS: The present study reviews the methods of presurgical fMRI language mapping and their dedicated fMRI tasks, specifically for patients with epilepsy. RESULTS: Different language tasks including verbal fluency are used in fMRI to determine language laterality and locality in different languages such as Persian. there are some considerations including the language materials and technical protocols for task design that all presurgical teams should take into consideration. CONCLUSION: Accurate presurgical language mapping is very important to preserve patients language after surgery. This review was the first part of a project for designing standard tasks in Persian to help precise presurgical evaluation and in Iranian PWFIE.

Outcome of epilepsy surgery in lesional epilepsy: Experiences from a developing country.

BACKGROUND: Our aim was to report the postoperative seizure outcome and associated factors in patients with lesional epilepsy, in a low-income setting. METHODS: This longitudinal prospective study included patients who underwent epilepsy surgery at Kashani Comprehensive Epilepsy Center between 2014 and 2019. Post-surgical outcomes were reported according to the Engel score, and patients were classified into two groups of seizure free (SF) and not-seizure free (NSF). RESULTS: A total of 148 adult patients, with a mean age of 30.45 ±â€¯9.23 years were included. The SF outcome was reported in 86.5% of patients and antiepileptic drugs (AEDs) were reduced or discontinued in 45.9%. The mean follow-up duration was 26.7 ±â€¯14.9 months. Temporal lobe lesions (76.3%) and mesial temporal sclerosis (MTS) (56.7%) were the most frequent etiologies. Temporal lesion (Incidence relative risk (IRR): 1.76, 95% CI [1.08-2.87], p = 0.023), prior history of CNS infection (IRR:1.18, 95% CI [1.03-1.35], p = 0.019), use of intra-operative ECoG (IRR:1.73, 95% CI [1.06-2.81], p = 0.028), and absence of IEDs in postoperative EEG (IRR: 1.41, 95% CI [1.18-1.70], p < 0.001) were positive predictors for a favorable outcome. CONCLUSION: Many patients with drug-resistant lesional epilepsy showed a favorable response to surgery. We believe that resective epilepsy surgery in low-income settings is a major treatment option. The high frequency of patients with drug-resistant epilepsy in developing countries is associated with high rates of morbidity and mortality. Hence, strategies to increase access to epilepsy surgery in these settings are urgently needed.

Comparison of Design Fluency Test Results among Patients with Parkinson's Disease, Frontotemporal Dementia, and the Control Group.

BACKGROUND: Design Fluency Test (DFT) is a nonverbal frame-free, nonstructured assessment of executive function (EF). Since previous studies evaluating EF in Parkinson's disease (PD) have mainly used verbal assessments for EF, this study aims to evaluate the pattern of executive domains in PD using DFT and to compare it with behavioral variant frontotemporal dementia (FTD) as a prototype for executive dysfunction and also with normal controls (NCs). MATERIALS AND METHODS: Twenty-eight patients with PD, 27 with FTD, and 27 NCs were included in the study in Ayatollah Kashani Neuropsychiatry Clinic affiliated to Isfahan University of Medical Sciences from September 2019 to February 2020. All participants were assessed via semi-structured neuropsychiatric interview, questionnaire for demographic profile (age, handedness, gender, education, and marital status), duration of illness, comorbid medical condition, comorbid psychiatric illnesses and medications, DFT, Short Parkinson's Evaluation Scale, Frontal Assessment Battery, Judgment of Line Orientation, and Neuropsychiatry Unit Cognitive Assessment Tool. RESULTS: Fixed condition novelty score was significantly different between FTD and PD (P < 0.001), FTD and control (P < 0.001), and also between PD and control (P = 0.001). When free and fixed condition novelty scores were considered to predict diagnostic attribution, multinomial logistic regression revealed that odds ratio for free condition novelty score was 0.705 (P = 0.005, 95% confidence interval [CI] = 0.553-0.899) and 0.494 (P = 0.001, 95% CI = 0.328-0.744) in PD and FTD, respectively. The odds ratio for fixed condition novelty score was 0.772 (P = 0.011, 95% CI = 0.632-0.942) and 0.449 (P = 0.00, 95% CI = 0.292-0.691). CONCLUSION: DFT subscores can be helpful in diagnosis and differentiation between FTD and PD.

National Guidelines for Cognitive Assessment and Rehabilitation of Iranian Traumatic Brain Injury Patients.

BACKGROUND: Individuals with moderate to severe traumatic brain injury (TBI) often have prolonged cognitive impairments, resulting in long-term problems with their real-life activities. Given the urgent need for evidence-based recommendations for neuropsychological management of Iranian TBI patients, the current work aimed to adapt eligible international guidelines for cognitive assessment and rehabilitation of the TBI patients in Iran. METHODS: The project was led by an executive committee, under the supervision of the Iranian Ministry of Health and Medical Education (MOHME). Following a systematic literature search and selection process, four guidelines were included for adaptation. Clinical recommendations of the source guidelines were tabulated as possible clinical scenarios for 90 PICO clinical questions covering all relevant phases of care. After summing up the scenarios, our initial list of recommendations was drafted according to the Iranian patients' conditions. The final decision-making, with the contribution of a national interdisciplinary panel of 37 experts from across the country, was conducted in two rounds using online and offline survey forms (Round 1), and face-to-face and telephone meetings (Round 2). RESULTS: A total of 63 recommendations in six sections were included in the final list of recommendations, among which 24 were considered as key recommendations. In addition, some of the recommendations were identified as fundamental, meaning that proper implementation of the other recommendations is largely dependent on their implementation. CONCLUSION: Iranian health policy makers and rehabilitation program managers are recommended to address some fundamental issues to provide the necessary infrastructure to set up an efficient cognitive rehabilitation service system.

Comparison of Cognitive Rehabilitation versus Donepezil Therapy on Memory Performance, Attention, Quality of Life, and Depression among Multiple Sclerosis Patients.

BACKGROUND: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system that affects cognitive performance and leads to depression and decreased quality of life (QOL). The current study aims to assess the effects of cognitive rehabilitation versus donepezil therapy on memory, attention, depression, and QOL in MS patients compared to placebo and control groups. METHODS: Eighty MS patients were randomly selected from parallel randomized trials and divided into four groups: A: cognitive rehabilitation (10 sessions of 120 minutes), B: control (no intervention), C: donepezil (10 mg daily), and D: placebo. Patients received the intervention for three months. They were assessed for cognitive status, depression, and QOL prior to the intervention and immediately after that using abbreviated mental test (AMT), prospective and retrospective memory questionnaire (PRMQ), everyday memory questionnaire (EMQ), digit span, MSQOL-54, and second edition Beck depression inventory (BDI). We compared scores between groups after the intervention, as well as the progression of scores in every single group. RESULT: s. The cognitive rehabilitation group showed improvement in EMQ, RPMQ, digit span, physical and mental health subscales of MSQOL54, and depression (P < 0.05). We observed the same effect for donepezil except for the digit span test (P = 0.15). Intergroup comparison of scores showed the superiority of cognitive rehabilitation over donepezil in digit span, depression, and mental health scores. CONCLUSION: Both donepezil and cognitive rehabilitation effectively improve memory performance, attention, depression, and QOL in MS patients. Cognitive rehabilitation is superior altogether. This study is registered with the Iranian registry of clinical trials http://clinicaltrials.gov/ct2/show/IRCT2016042227522N1.

Language representation and presurgical language mapping in pediatric epilepsy: A narrative review.

As one of the most common neurological diseases in children, epilepsy affects 0.9-2% of children. Complex interactions among the etiologies of epilepsy, interictal discharges, seizures, and antiepileptic drugs lead to cognitive impairments in children with epilepsy. Since epilepsy is considered as a network disorder, in which seizures have a widespread impact on many parts of the brain, childhood epilepsy can even affect the normal development of language. About 25% of children with epilepsy do not respond to medications; therefore, brain surgery is considered as a treatment option for some of them. Presurgical neuropsychological evaluations including language mapping are recommended to preserve cognitive and language abilities of patients after surgery. Functional magnetic resonance imaging as a non-invasive technique for presurgical language mapping has been widely recommended in many epileptic centers. The present study reviewed language representation and presurgical language mapping in children with epilepsy. Mapping language in children with epilepsy helps to localize the epileptogenic zone, and also, to predict the cognitive outcome of epilepsy surgery and possible cognitive rehabilitation. This review collected information about language representation and language mapping in pediatric epilepsy settings.

The Epigenetic Overlap between Obesity and Mood Disorders: A Systematic Review.

(1) Background: Obesity and mood disorders are considered as the most prevalent morbidities in many countries. We suppose that epigenetic mechanisms may induce higher rates of obesity in subjects who suffer from mood disorders. In this systematic review, we focused on the potential roles of DNA methylation on mood disorders and obesity development. (2) Methods: This systematic review was conducted in accordance with the PRISMA statement and registered in Prospero. A systematic search was conducted in MEDLINE, Scopus, Web of Science, Cochrane Central database, EMBASE, and CINHAL. We also conducted a Grey literature search, such as Google Scholar. (3) Results: After deduplication, we identified 198 potentially related citations. Finally, ten unique studies met our inclusion criteria. We have found three overlap genes that show significant DNA methylation changes, both in obesity and depression. Pathway analysis interaction for TAPBP, BDNF, and SORBS2 confirmed the relation of these genes in both obesity and mood disorders. (4) Conclusions: While mechanisms linking both obesity and mood disorders to epigenetic response are still unknown, we have already known chronic inflammation induces a novel epigenetic program. As the results of gene enrichment, pathways analysis showed that TAPBP, BDNF, and SORBS2 linked together by inflammatory pathways. Hypermethylation in these genes might play a crucial rule in the co-occurrence of obesity and mood disorders.

A systematized review of cognitive load theory in health sciences education and a perspective from cognitive neuroscience.

INTRODUCTION: To design instructions in health sciences education, it is highly relevant to heed the working memory and the approaches for managing cognitive load. In this article, we tried to mention the implications of cognitive load theory (CLT) for optimizing teaching-learning in health sciences education and discussing cognitive load from the perspective of cognitive neurosciences as brain-aware medical education. MATERIALS AND METHODS: We searched databases of Pubmed, Proquest, SCOPUS, and ISI Web of Science for relevant literature in September 1, 2018. RESULTS: The 27 articles out of a total of 46 records, along with 23 papers from snowballing and hand searching were included in this study. Main items encompassed; "Various types of cognitive loads," "Aim of cognitive load theory," "Strategies to managing Cognitive Load," "Cognitive Load Theory in novice and experienced learners and "expertise reversal effect," Medical and Health Sciences Curriculums and Cognitive Load Theory," "Challenges of Cognitive Load Theory." CONCLUSIONS: We discussed six important themes for CLT in health sciences education according to the literature. Mental imagery (visualization) as one of the useful techniques to optimize germane load was suggested, as it processes further gain access to neural circuits that are engaged in sensory, motor, executive, and decision-making pathways in the brain.

Effect of Donepezil on Cognitive Impairment, Quality of Life, and Depression in Multiple Sclerosis Patients: A Randomized Clinical Trial.

BACKGROUND: Cognitive impairment is one of the debilitating consequences of multiple sclerosis (MS) with negative effects on daily life, individual and social activities, quality of life (QOL), and depression. No approved medication is introduced so far for affected individuals. We aimed to evaluate the efficacy of donepezil on cognitive performance, QOL, and depression in MS. METHODS: This is a double-blinded randomized clinical trial conducted on 100 patients with MS during 2018. Patients were assessed prior to intervention abbreviated mental test (AMT), prospective and retrospective mental questionnaire (PRMQ), everyday memory questionnaire (EMQ), digit span test, Beck depression inventory (BDI), and MSQOL questionnaire. Then patients were randomly divided into two groups of treatment (daily regimen of 10 mg donepezil) and placebo for 3 months. Subjects were reassessed using the same instruments at the end of intervention. RESULTS: Fifty patients remained in each group at the end of study. The mean age in donepezil and placebo groups was 31.9 ± 5.89 and 30.65 ± 5.43 years, respectively. EMQ, PRMQ, digit span test, MSQOL, and depression scores improved following donepezil therapy (P < 0.001) while no statistically significant difference was found in the placebo group (P > 0.05). Comparison of two groups also showed more favorable scores in donepezil group with respect to all assessment tools (P < 0.001). CONCLUSIONS: Donepezil could effectively improve cognitive impairment in MS patients. Also, its positive effect on QOL and depression could result in a smaller number of interventions in this group of patients.

Lavender and dodder combined herbal syrup versus citalopram in major depressive disorder with anxious distress: A double-blind randomized trial.

BACKGROUND: Major depressive disorder (MDD) accompanied by anxious distress is a chronic and disabling disorder. Its conventional drug therapies often have low patient compliance due to drug-related side effects. In Persian medicine, lavender-dodder syrup is one formula often recommended for such disorders. OBJECTIVE: This study compares the effects of lavender-dodder syrup to the standard drug, citalopram, for treating MDD with anxious distress. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This six-week, double-blind, randomized, clinical trial was carried out in a psychiatric outpatient clinic. During the six-week intervention period, patients in citalopram group received citalopram tablets 20 mg/d plus 5 mL placebo syrup every 12 h; patients in group B received placebo tablets once daily plus 5 mL of lavender-dodder herbal syrup every 12 h. MAIN OUTCOME MEASURES: Primary outcome measures, depression and anxiety, were evaluated using the Hamilton Depression/Anxiety Rating Scales, and were scored at the beginning of the study and at weeks three and six. Secondary outcome measures including response to treatment and remission rates were also compared between the two groups. RESULTS: Fifty-six participants with MDD and anxious distress were randomly assigned to two groups. Mean depression scores significantly decreased in citalopram and herbal groups at weeks three and six (time effect: P < 0.001), although the observed changes were not significantly different between the groups (intervention effect: P = 0.61). Mean anxiety scores were not significantly different between the two groups at week three (P = 0.75). However, at the end of week six, the observed decrease was significantly higher in the herbal syrup group than the citalopram group (intervention effect: P = 0.007). CONCLUSION: The herbal syrup is an effective and tolerable supplement for treating MDD with anxious distress. TRIAL REGISTRATION NUMBER: IRCT2016102430459N1 on Iranian Registry of Clinical Trials.

Stress as a challenge in promoting mental health among dementia caregivers.

BACKGROUND: Caregiver stress is harmful to the health of both caregivers and people living with Alzheimer's disease or other dementias. The present study was conducted to assess stress and its predictors of people living with Alzheimer's disease or other dementias' caregivers. METHODS: The present descriptive, analytical, cross-sectional study was conducted in December 2017-June 2018 in Isfahan, Iran. Data were collected by interviewing 99 caregivers had at least 6 months of experience caring for a patient diagnosed with Alzheimer's disease, through questionnaires developed by the researcher. A convenience sample (easy access) of caregivers was recruited from calling the home of formally diagnosed with Alzheimer's patient, that have registered in educational hospitals affiliated to Isfahan University of Medical Sciences and psychiatrists' office both paid caregivers (formal) and unpaid caregivers (family). All caregivers provided informed consent. The type and severity of the relationship between the dependent (stress) and independent variable were assessed using Pearson's and Spearman's correlation coefficients, the independent t-test, and the multivariate regression analysis. RESULTS: The caregivers' mean stress score was 25.4 ± 10.9 (range: 4-54). About 80% of the caregivers were female. Age and stress score was correlated (P = 0.004), the mean stress score was significantly higher in female caregivers (P = 0.04), informal caregivers (P < 0.001), and significantly lower in the caregivers with previous experience of caring for Alzheimer's patients (P = 0.02) or those introduced by service companies (P = 0.005). Variables including the family relationship with the patient (P = 0.01), kind of caregiving (P = 0.03), and previous experience of caring for Alzheimer's patients (P = 0.04) were stronger predictors of the stress score. CONCLUSION: Stress is a challenge in promoting mental health among dementia caregivers. Providing social support with an emphasis on physical, mental, and social health is mandatory, especially for female and family caregivers, to promote stress management, mental health in this group, and enable optimal and purposeful care.

The Relationship between Aura and Postoperative Outcomes of Epilepsy Surgery in Patients with Mesial Temporal Sclerosis.

BACKGROUND: We conducted a study to evaluate the relationship between aura types and postoperative outcomes in patients with mesial temporal sclerosis (MTS) to predict the prognosis of patients, accordingly. MATERIALS AND METHODS: In this cross-sectional study, 99 patients with MTS-temporal lobe epilepsy were enrolled based on inclusion and exclusion criteria. The types of aura were evaluated, and the outcomes were categorized according to the Engel scale. Preoperative and postoperative results of patients were compared and analyzed with the Kruskal-Wallis test. RESULTS: About 73.7% of patients had seizure-free after their surgeries. The most of patients (n = 81) were in Class I of Evaluating Engel criteria. About 36.3% had not experienced any aura before their seizures, and among those with aura, the most prevalent aura was abdominal aura in 29 patients (29.3%) followed by other types of aura and affective aura. Most of the patients in Class I, II, III, and IV of Engel scale had an abdominal aura, without aura, effective aura, and abdominal aura, respectively, but this difference was not statistically significant (P = 0.691). CONCLUSION: According to this study, the type of aura cannot predict postoperative outcomes in MTS patients. More studies are needed to evaluate this relation in better-planned studies with greater sample size.

What motivates informal caregivers of people with dementia (PWD): a qualitative study.

BACKGROUND: The burden of caring for People with Dementia (PWD) is heavy; identifying incentives that motivate them in providing care is essential in facilitating and optimizing care. This study aims to explore and describe these motivating factors. METHODS: We conducted this qualitative study between January 2016 and January 2017 in Isfahan, Iran. Data were extracted through in-depth, semi-structured interviews with 19 caregivers of PWD. These data were then examined through thematic content analysis. RESULTS: We identified four categories of psychological motives based on the caregivers' feedback and experience. These include 1) Moral-based motives, 2) Religious, and spiritual motives; 3) Financial motives, and 4) Wicked motives. CONCLUSIONS: Our results revealed several aspects of caregivers' motives. They include moral, religious, and spiritual aspects; sharing housing accommodations, and the likelihood of inheriting a portion of the patient's assets based on unspoken rules and informal arrangements in the family, and wicked and immoral aspects. These findings can inform future efforts in enhancing the experiences of caregivers of PWD, and subsequently, the quality of care these patients receive. It further suggests that family members, members of a religious and spiritual organization, as well as social media, could play important roles in setting the stage.

Outcome of lesional epilepsy surgery: Report of the first comprehensive epilepsy program in Iran.

BACKGROUND: We investigated the utility of epilepsy surgery and postoperative outcome in patients with lesional epilepsy in Iran, a relatively resource-poor setting. METHODS: This prospective longitudinal study was conducted during 2007-2017 in Kashani Comprehensive Epilepsy Center, Isfahan, Iran. Patients with a diagnosis of intractable focal epilepsy, with MRI lesions, who underwent epilepsy surgery and were followed up ≥ 24 months, were included and evaluated for postoperative outcome. RESULTS: A total of 214 patients, with a mean age of 26.90 ± 9.82 years (59.8% men) were studied. Complex partial seizure was the most common type of seizure (85.9%), and 54.2% of the cases had auras. Temporal lobe lesions (75.2%) and mesial temporal sclerosis (48.1%) were the most frequent etiologies. With a mean follow-up of 62.17 ± 19.33 months, 81.8% of patients became seizure-free postoperatively. Anticonvulsants were reduced in 86% of the cases and discontinued in 40.7%. In keeping with previous studies, we found that seizure freedom rates were lower among patients with longer follow-up periods. CONCLUSIONS: We found high rates of seizure freedom after surgery in lesional epilepsy patients despite limited facilities and infrastructure; antiepileptic medications were successfully tapered in almost half of the patients. Considering the favorable outcome of epilepsy surgery in our series, we believe that it is a major treatment option, even in less resource-intensive settings, and should be encouraged. Strategies to allow larger scale utility of epilepsy surgery in such settings in the developing world and dissemination of such knowledge may be considered an urgent clinical need, given the established mortality and morbidity in refractory epilepsy.

Evaluation of dual pathology among drug-resistant epileptic patients with hippocampal sclerosis.

PURPOSE: Dual pathology (DP) is defined as simultaneous presence of hippocampal sclerosis (HS) and any other pathology in the brain. Since this is a less probed concept, we aimed to evaluate the frequency and characteristics of DP among drug-resistant epileptic patients with HS. METHODS: This is a cross-sectional study conducted during 2007-2016 in Kashani Comprehensive Epilepsy Center, Isfahan, Iran. Patients with diagnosis of drug-resistant epilepsy and HS were enrolled in the study, and demographic data, seizure semiology, EEG findings, and MRI findings were collected. We compared these variables between three groups of DP, unilateral HS, and bilateral HS. RESULTS: Of the 200 enrolled cases, 29 patients (14.5%) had DP and 21 patients (10.5%) had bilateral HS; the remaining patients had unilateral HS. The average age of patients with DP was 30.03, and 65.5% of them were male. Patients with DP had more EEG discharges from regional and multi-focal sites compared to unilateral HS (P value < 0.001). Also, complex partial seizure (CPS) was more commonly presented in patients with unilateral HS (96.8%). Comparison of disease characteristics between DP and bilateral HS showed no difference in most categories (P > 0.05). CONCLUSIONS: We found DP among 14.5% of our drug-resistant epileptic patients with HS. DP patients mostly presented with CPS and had high proportion of ictal and interictal EEG discharges from regional and multi-focal areas. Gliosis and focal cortical dysplasia were the most common pathologies among DP patients. Patients with DP showed a similar behavior to bilateral HS in many features.
