RESUMEN
Epilepsy is a common medical condition that affects people of all ages, races, social classes, and geographical regions. Diagnosis of epilepsy remains clinical, and ancillary investigations (electroencephalography, imaging, etc) are of aid to determine the type, cause, and prognosis. Antiseizure medications represent the mainstay of epilepsy treatment: they aim to suppress seizures without adverse events, but they do not affect the underlying predisposition to generate seizures. Currently available antiseizure medications are effective in around two-thirds of patients with epilepsy. Neurosurgical resection is an effective strategy to reach seizure control in selected individuals with drug-resistant focal epilepsy. Non-pharmacological treatments such as palliative surgery (eg, corpus callosotomy), neuromodulation techniques (eg, vagus nerve stimulation), and dietary interventions represent therapeutic options for patients with drug-resistant epilepsy who are not suitable for resective brain surgery.

Safe delivery and optimal peripartum and postpartum care in women with epilepsy (WWE) is a major concern which has received limited attention in recent years. A diagnosis of epilepsy per se is not an indication for a planned cesarean section or induction of labor, even though epidemiological studies indicate that cesarean delivery is more common among WWE compared to the general population. Pregnancy in WWE is associated with an increased risk of obstetrical complications and increased perinatal morbidity and mortality, and these risks may be greater among WWE taking ASMs. Wherever feasible, pregnant WWE should be directed to specialist care. Risk minimization includes, when appropriate, dose adjustment to compensate for pregnancy-related changes in the pharmacokinetics of some ASMs. With respect to postpartum management, WWE should be advised that the benefits of breastfeeding outweigh the small risk of adverse drug reactions in the infant.

OBJECTIVE: We investigated the frequency of coexistence of temporal lobe epilepsy (TLE) and idiopathic generalized epilepsy (IGE) in a retrospective database study. We also explored the underlying pathomechanisms of the coexistence of TLE and IGE based on the available information, using bioinformatics tools. METHODS: The first phase of the investigation was a retrospective study. All patients with an electro-clinical diagnosis of epilepsy were studied at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, Shiraz, Iran, from 2008 until 2023. In the second phase, we searched the following databases for genetic variations (epilepsy-associated genetic polymorphisms) that are associated with TLE or syndromes of IGE: DisGeNET, genome-wide association study (GWAS) Catalog, epilepsy genetic association database (epiGAD), and UniProt. We also did a separate literature search using PubMed. RESULTS: In total, 3760 patients with epilepsy were registered at our clinic; four patients with definitely mixed TLE and IGE were identified; 0.1% of all epilepsies. We could identify that rs1883415 of ALDH5A1, rs137852779 of EFHC1, rs211037 of GABRG2, rs1130183 of KCNJ10, and rs1045642 of ABCB1 genes are shared between TLE and syndromes of IGE. CONCLUSION: While coexistence of TLE and IGE is a rare phenomenon, this could be explained by shared genetic variations.

BACKGROUND: The stigma toward epilepsy is a daily challenge for people with epilepsy (PWE) and can influence the well-being and prognosis of these individuals. However, the cultural origins of such stigma have sparsely been examined. In this study, we aimed to investigate the classic Persian literature to gain insight into the historical and cultural beliefs and opinions regarding epilepsy as a determinant in developing stigma towards PWE. METHODS: In this narrative review of the classic Persian literature, we investigated the opinions and beliefs regarding epilepsy and PWE. In February 2023, we searched https://ganjoor.net (an open-access database of Iranian literature) for the relevant literary materials (poem and prose) using the Persian translation of the terms epilepsy (Sar'e) and epileptic (Masroo'e). Two clinical researchers went through the results and extracted the related materials under the supervision of two experts in Persian literature. A bilingual academic translated the included literary materials from Persian to English. RESULTS: Our search yielded 57 literature materials by 31 poets and writers from the 4th to 14th Hijri centuries, roughly coinciding with the past Gregorian millennium (1000-2000 AC). We classified the literary concepts related to epilepsy stigma into five subgroups: (i) a simile for pain and suffering; (ii) an atonement for blasphemous beliefs or a disease caused by supernatural power; (iii) a sign of madness, insanity, and lack of wisdom; (iv) a celestial observation; and (v) a subject for jokes. CONCLUSIONS: Classic Persian literature considered epilepsy as a simile for suffering and a sign of insanity that is caused by blasphemous beliefs or celestial objects, with PWE classified as insane and unwise. While such depictions became less prevalent after the 14th century CE, they can give rise to misconceptions and negative stigma toward PWE and should be addressed in modern culture. Each society should critically investigate its socio-cultural origins of stigma and rectify such misbeliefs.

OBJECTIVE: Genetic factors have long been debated as a cause of failure of surgery for mesial temporal lobe epilepsy (MTLE). We investigated whether rare genetic variation influences seizure outcomes of MTLE surgery. METHODS: We performed an international, multicenter, whole exome sequencing study of patients who underwent surgery for drug-resistant, unilateral MTLE with normal magnetic resonance imaging (MRI) or MRI evidence of hippocampal sclerosis and ≥2-year postsurgical follow-up. Patients with either sustained seizure freedom (favorable outcome) or ongoing uncontrolled seizures since surgery (unfavorable outcome) were included. Exomes of controls without epilepsy were also included. Gene set burden analyses were carried out to identify genes with significant enrichment of rare deleterious variants in patients compared to controls. RESULTS: Nine centers from 3 continents contributed 206 patients operated for drug-resistant unilateral MTLE, of whom 196 (149 with favorable outcome and 47 with unfavorable outcome) were included after stringent quality control. Compared to 8,718 controls, MTLE cases carried a higher burden of ultrarare missense variants in constrained genes that are intolerant to loss-of-function (LoF) variants (odds ratio [OR] = 2.6, 95% confidence interval [CI] = 1.9-3.5, p = 1.3E-09) and in genes encoding voltage-gated cation channels (OR = 2.4, 95% CI = 1.4-3.8, p = 2.7E-04). Proportions of subjects with such variants were comparable between patients with favorable outcome and those with unfavorable outcome, with no significant between-group differences. INTERPRETATION: Rare variation contributes to the genetic architecture of MTLE, but does not appear to have a major role in failure of MTLE surgery. These findings can be incorporated into presurgical decision-making and counseling. ANN NEUROL 2022.
RESUMEN
PURPOSE: The current systematic review aimed to investigate whether living under the sea or in space is detrimental for patients with epilepsy (PWE). We hypothesized that living under such conditions may predispose PWE to experience seizure recurrence by altering their brain function in a way that predisposes them to seizures. METHODS: This systematic review is reported according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. On October 26, 2022, we systematically searched PubMed, Scopus, and Embase for relevant articles. RESULTS: Our endeavor yielded six papers. One study provided level 2 of evidence, while the rest of the publications provided level 4 or 5 of evidence. Five publications were about the effects of space missions (or simulations), and one manuscript discussed the impacts of underwater experience. CONCLUSION: Currently, there is no evidence to make any recommendations about living in extremes of the universe (space and under the sea) with epilepsy. The scientific community should invest more time and effort in comprehensively investigating the potential risks associated with missions and living in such conditions.

BACKGROUND: We investigated childhood-onset functional seizures (FS) and late-onset FS and hypothesized that there are differences in their characteristics. METHODS: In this retrospective study, we investigated all patients with confirmed FS with an age at onset of 14 years or younger and those with an age at onset of 50 years or older, who were admitted to the epilepsy monitoring units at one center in Iran (Shiraz Comprehensive Epilepsy Center, from 2008 until 2022) and one center in the USA (Vanderbilt University Medical Center, from 2011 until 2022). RESULTS: One-hundred and forty patients were included. They included 80 patients with childhood-onset FS and 60 with late-onset FS. Those with late-onset FS were more likely to have medical comorbidities compared with the patients with childhood-onset FS (OR = 13.9). Those with late-onset FS more likely had a history of head injury compared with the patients with childhood-onset FS (OR = 5.97). Duration of illness was significantly longer in patients with childhood-onset FS compared with the patients with late-onset FS (6 years vs. 2 years). CONCLUSION: Our study identified several similarities and differences in the clinical characteristics and predisposing factors of patients with childhood-onset and late-onset FS. In addition, we found that childhood-onset FS is more likely to remain undiagnosed and thus untreated for many years. These findings provide additional evidence that FS is a heterogenous condition and we propose that a proportion of the differences between patients may be accounted for by age-associated factors.

Unlike several epilepsies with onset in pediatric age, adult-onset epilepsies do not typically have a time course that is predictably self-remitting in the large majority of people. Still, about one-half of individuals with adult-onset epilepsy who have been seizure-free for an extended period (two years or longer) on antiseizure medications (ASMs) will remain in remission when their drug therapy is discontinued. Although a number of predictors of outcome have been identified (including specific adult-onset syndromes associated with a low probability of spontaneous remission), in most cases, the only way to establish whether the epilepsy has remitted in a given individual is to gradually withdraw ASMs. ASM withdrawal can be beneficial, particularly when the currently used treatment is not well tolerated, or could lead to adverse outcomes in the future (i.e., teratogenic effects should pregnancy occur in a female of childbearing potential). However, the risks associated with ASM withdrawal are significant. Relapse of seizures can have major adverse psychosocial consequences and also may carry a risk of morbidity and mortality. Most importantly, evidence suggests that in about 20% of individuals whose seizure relapsed following ASM withdrawal, re-institution of pharmacological therapy may not readily restore seizure control. Ultimately, management decisions should prioritize the preference of the well-informed person with epilepsy. Particularly, when adverse drug effects are a concern, options to be discussed should include not only withdrawal or continuation of the current treatment but also dose reduction or substitution with a different ASM.

BACKGROUND: Three years ago (in 2020), we at the epilepsy center in Shiraz, Iran, started an endeavor to initiate a surgical program for patients with hypothalamic hamartoma (HH). We discussed that although minimally invasive techniques are desired, they are not available in the nation. We decided to proceed with open disconnection and resection surgery techniques. The current manuscript presents the results of the HH surgery program at our center as a case series. METHODS: This study included all patients with a diagnosis of HH who were referred to Shiraz Epilepsy Center with drug-resistant epilepsy and who underwent HH surgery from October 2020 to January 2023 at our epilepsy center, Namazi Hospital, Shiraz, Iran. RESULTS: Seven patients were included. All patients had gelastic seizures. Four patients (57%) underwent total resection of HH, and the lesions were disconnected and partially resected in three other patients (43%). Three patients (43%) became seizure-free after surgery, and three patients (43%) had more than 50% reduction in their seizure frequencies. Three patients (43%) had no post-operative complications. Only one patient (14.3%) suffered from a permanent postoperative complication (right hemiparesis). The mortality rate was zero. Five parents (71%) were satisfied with the surgery outcomes. CONCLUSION: Hypothalamic hamartoma surgery is feasible even in centers with limited resources if a close collaboration exists between the epileptology and neurosurgery teams. Careful planning based on the expertise of the team members and the available resources is required to foster success.
RESUMEN
OBJECTIVE: The goal of the current study was to investigate the opinions of adult patients with epilepsy (PWE) with regard to the application of epilepsy surgery for their condition. METHODS: We surveyed all the consecutive adult PWE with at least one year history of epilepsy who were referred to our neurology clinics (Shiraz University of Medical Sciences) from September 2022 until January 2023. Using a questionnaire, the degree of acceptance of epilepsy surgery was measured depending on the chance of seizure freedom and risk for surgery complications. RESULTS: In total, 393 adult PWE participated in the study; 180 patients (45.8%) expressed that they would be willing to have surgery if their epilepsy doctor told them that brain surgery was guaranteed to stop their seizures, without regard to the potential surgery complications. The most common reasons for the patients to be willing to have epilepsy surgery were as follows: to become seizure-free and to be able to discontinue their antiseizure medications. The most common reasons for the patients not to be willing to have epilepsy surgery were as follows: feeling of having the seizures under the control with antiseizure medications and fear of surgery complications. CONCLUSION: Many patients with epilepsy are willing to have epilepsy surgery if their physician presented epilepsy surgery to them as an established safe and effective treatment option. The important values and priorities of PWE must be considered when designing epilepsy surgery educational materials and programs for preoperative counseling for PWE with drug-resistant seizures.

PURPOSE: We conducted an observational study to investigate the opinions of neurologists and psychiatrists all around the world who are taking care of patients with seizures [epilepsy and functional seizures (FS)]. METHODS: Practicing neurologists and psychiatrists from around the world were invited to participate in an online survey. On 29th September 2022, an e-mail including a questionnaire was sent to the members of the International Research in Epilepsy (IR-Epil) Consortium. The study was closed on 1st March 2023. The survey, conducted in English, included questions about physicians' opinions about FS and anonymously collected data. RESULTS: In total, 1003 physicians from different regions of the world participated in the study. Both neurologists and psychiatrists identified "seizures" as their preferred term. Overall, the most preferred modifiers for "seizures" were "psychogenic" followed by "functional" by both groups. Most participants (57.9%) considered FS more difficult to treat compared to epilepsy. Both psychological and biological problems were considered as the underlying cause of FS by 61% of the respondents. Psychotherapy was considered the first treatment option for patients with FS (79.9%). CONCLUSION: Our study represents the first large-scale attempt of investigating physicians attitudes and opinions about a condition that is both frequent and clinically important. It shows that there is a broad spectrum of terms used by physicians to refer to FS. It also suggests that the biopsychosocial model has gained its status as a widely used framework to interpret and inform clinical practice on the management of patients.

INTRODUCTION: We investigated the longevity of COVID-associated brain fog in patients who have survived the COVID-19. METHODS: This was a follow-up study of 2,696 adult patients with COVID-19 from our previous study. We selected every other patient in our database. The follow-up data were collected during a phone call to the participants in January-February 2022 (11 months after the initial study): concentration difficulty and the patient's self-declared status in their ability to concentrate. RESULTS: In total, 1,164 people were included; 35 people (3.0%) had concentration difficulty and 65 individuals (5.6%) had a worsened status in their ability to concentrate and think; 26 people (2.2%) responded yes to both questions and were considered as having long-lasting brain fog. People with long-lasting brain fog were more often admitted to ICUs during the initial hospitalization (23.1% vs. 9.3%; p = 0.032) compared with those without long-lasting brain fog. CONCLUSION: We may conclude that a minority of the hospitalized patients with COVID-19 may suffer from long-lasting post-COVID brain fog, at least for more than 1 year after their initial illness. Long-lasting post-COVID brain fog has a significant association with the severity of the initial illness.

AIM: Psychogenic nonepileptic seizures (PNES) or functional seizures are universal phenomena. However, data on their epidemiology is limited. The aim of the current study was to review the literature on the epidemiology of PNES and to provide analytical estimates of its incidence and prevalence based on the direct data that are available from previous studies on PNES. METHODS: The methods of this work had two parts: (1) MEDLINE, PsycINFO, and Scopus from inception to 19 October 2019 were systematically searched. (2) The analytical study of the incidence and prevalence of PNES was performed, based on the following data from previous studies: incidence of PNES, duration of PNES before making a diagnosis, outcome and mortality of PNES. RESULTS: The search strategy yielded five articles; three were on the incidence and two on the prevalence. In the analytical part of the study, the incidence of PNES was calculated to be 3.1 (95% Confidence Interval: 1.1-5.1) per 100,000 population per year. The calculated prevalence rate of PNES in 2019 was 108.5 (95% Confidence Interval: 39.2-177.8) per 100,000 population, in the USA. CONCLUSION: While, the generalizability of these calculated incidence and prevalence rates to other places in the world is limited, they give us a reasonable hint that PNES is a common condition and the prevalence is much more than that it was thought before.Supplemental data for this article is available online at https://doi.org/10.1080/00207454.2021.1942870.

We investigated the frequency of brain fog in a large cohort of patients with documented coronavirus disease-2019 (COVID-19) who have survived the illness. We also scrutinized the potential risk factors associated with the development of brain fog. Adult patients (18-55 years of age), who were referred to the healthcare facilities anywhere in Fars province from February 19, 2020 to November 20, 2020 were included. All patients had a confirmed COVID-19 diagnosis. In a phone call, at least 3 months after their discharge from the hospital, we obtained their current information. A questionnaire was specifically designed for data collection. In total, 2696 patients had the inclusion criteria; 1680 (62.3%) people reported long COVID syndrome (LCS). LCS-associated brain fog was reported by 194 (7.2%) patients. Female sex (odds ratio [OR]: 1.4), respiratory problems at the onset (OR: 1.9), and intensive care unit (ICU) admission (OR: 1.7) were significantly associated with reporting chronic post-COVID "brain fog" by the patients. In this large population-based study, we report that chronic post-COVID "brain fog" has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness (ICU admission).

BACKGROUND AND PURPOSE: Antiseizure medications (ASMs) should be tailored to individual characteristics, including seizure type, age, sex, comorbidities, comedications, drug allergies, and childbearing potential. We previously developed a web-based algorithm for patient-tailored ASM selection to assist health care professionals in prescribing medication using a decision support application (https://epipick.org). In this validation study, we used an independent dataset to assess whether ASMs recommended by the algorithm are associated with better outcomes than ASMs considered less desirable by the algorithm. METHODS: Four hundred twenty-five consecutive patients with newly diagnosed epilepsy were followed for at least 1 year after starting an ASM chosen by their physician. Patient characteristics were fed into the algorithm, blinded to the physician's ASM choices and outcome. The algorithm recommended ASMs, ranked in hierarchical groups, with Group 1 ASMs labeled as the best option for that patient. We evaluated retention rates, seizure freedom rates, and adverse effects leading to treatment discontinuation. Survival analysis contrasted outcomes between patients who received favored drugs and those who received lower ranked drugs. Propensity score matching corrected for possible imbalances between the groups. RESULTS: Antiseizure medications classified by the algorithm as best options had a higher retention rate (79.4% vs. 67.2%, p = 0.005), higher seizure freedom rate (76.0% vs. 61.6%, p = 0.002), and lower rate of discontinuation due to adverse effects (12.0% vs. 29.2%, p < 0.001) than ASMs ranked as less desirable by the algorithm. CONCLUSIONS: Use of the freely available decision support system is associated with improved outcomes. This drug selection application can provide valuable assistance to health care professionals prescribing medication for individuals with epilepsy.

OBJECTIVE: To re-assess the definition of drug-resistant epilepsy based on the evidence from a large-scale, long-term study including both adults and children. We categorized the patients as idiopathic generalized epilepsies (IGEs), focal epilepsies, or structural-metabolic-genetic generalized epilepsies [symptomatic generalized epilepsies (SGEs)] and provided the definition of drug-resistance based on the epilepsy types of the patients. METHODS: This was a longitudinal study of a prospectively developed and maintained database. All patients with an electro-clinical diagnosis of IGE, focal epilepsy, or SGE, who received treatment from 2008 to 2021, were recruited at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, Shiraz, Iran. All patients had to be followed at our center for at least 24 months. The receiver operating characteristic curve (ROC curve) was used for the statistical analysis. RESULTS: The included patients were as follows: 523 with focal epilepsy, 218 with IGE, and 211 with SGE. For all epilepsy types, the ROC curves of the number of appropriately prescribed antiseizure medications (ASMs) were acceptable indicators to anticipate drug-resistance. The best cutoff point for focal epilepsies was at 4 ASMs (sensitivity: 0.56, specificity: 0.81); for IGE, at 3 ASMs (sensitivity: 0.51, specificity: 0.80); and for SGEs, at 4 ASMs (sensitivity: 0.78, specificity: 0.58). CONCLUSION: The definition of drug-resistant epilepsy should be different in various epilepsy types. It is the time for the scientific community to reappraise the definition of drug-resistant epilepsy in the light of the new evidence that has become available in the past 11 years since the previously published definition.

The aim of this systematic review was to provide the required information regarding different aspects of the relationship between epilepsy/antiseizure medications and non-alcoholic drinks. The recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement were followed. MEDLINE and Scopus from the inception until 7 August 2021 were systematically searched. These key words were used: "epilepsy" OR "seizure" OR "antiepileptic" OR "antiseizure" OR "anticonvulsant" AND "coffee" OR "tea" OR "soda" OR "juice" OR "drink" OR "cola" OR "diet" (35 key word combinations). The primary search yielded 21 458 publications (PubMed, n = 4778; Scopus, n = 16 680). Only 50 studies met all the inclusion criteria and were included in the current systematic review. In total, 17 articles investigated various non-alcoholic drinks in human studies, 11 studies were case reports/series, and 22 articles were animal/in vitro studies. None of the studies provided a class 1 of evidence. There is limited evidence suggesting that certain drinks (eg, caffeinated energy drinks) might trigger seizures. Patients with epilepsy should avoid excessive consumption of certain fruit juices (eg, grapefruit, lime, pomegranate, kinnow, and star fruit) and caffeinated drinks. However, daily coffee and tea intake can be part of a healthy balanced diet, and their consumption does not need to be stopped in patients with epilepsy. Coffee/tea consumption is not harmful if consumed at levels of 200 mg (caffeine) in one sitting (about 2½ cups of coffee) or 400 mg daily (about five cups of coffee).

OBJECTIVE: This survey aimed to investigate the opinions of the parents of children with epilepsy with regard to the application of epilepsy surgery for their children. METHODS: We surveyed all the parents of children with epilepsy referred to our neurology clinic (Shiraz University of Medical Sciences) in April-July 2022. We collected their opinions about epilepsy surgery based on a predesigned questionnaire. The inclusion criteria included parents of all children with epilepsy (1 to 16 years of age, with at least one-year history of epilepsy, and with at least one drug used in the past 12 months). RESULTS: In total, 472 people participated in the study; 277 participants (58.7%) were willing to have epilepsy surgery for their child; the most common reason was to be able to discontinue the drugs. Sex (male), age (younger), and education (college) of the parents had significant associations with the parental willingness to have surgery for their children. The patient's drug regimen (polytherapy) and history of ictal injury (in the child) also had significant associations with the parental willingness to have surgery for the children. CONCLUSION: Most parents of children with epilepsy are willing to have epilepsy surgery for their children if their physician presents epilepsy surgery to them as an established, safe, and effective treatment option. Patient and parental-related factors should be considered when designing educational materials and programs for preoperative counseling for the parents of children with drug-resistant seizures.

OBJECTIVES: We applied the Two-Step cluster analysis on a large cohort of patients with functional seizures (FS). We studied whether the background risk factors differed between the patient clusters. METHODS: All patients with a diagnosis of FS were studied at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, Shiraz, Iran, from 2008 until 2021. The Two-Step cluster analysis was applied considering the age at onset, sex, and seizure semiology. We also studied whether the background risk factors (e.g., a history of sexual abuse, physical abuse, etc.) differed between these patient clusters. RESULTS: Three-hundred and fifty four patients were studied. The Two-Step cluster analysis was applied to the 230 patients who reported any associated risk factors; there were three clusters of patients. The most prominent feature of cluster 1 included akinetic seizures. The most prominent features of cluster 2 included motor seizures and no ictal injury. The most prominent features of cluster 3 included motor seizures with ictal injury. Compared with patients in cluster 3, a history of sexual abuse was more often reported by patients in cluster 1 (OR: 3.26, 95%CI: 1.12-9.47; pâ¯=â¯0.03). Compared with patients in cluster 3, a history of physical abuse was less often reported by patients in cluster 2 (OR: 0.45, 95%CI: 0.22-0.90; pâ¯=â¯0.026). CONCLUSION: The Two-Step cluster analysis could identify three distinct clusters of patients based on their demographic and clinical characteristics. These clusters had correlations with the associated risk factors in patients with FS.

OBJECTIVES: We applied the Two-Step cluster analysis on a large cohort of patients with temporal lobe epilepsy (TLE). We hypothesized that there are distinct clusters of patients with TLE based on their clinical characteristics and these clusters may predict their seizure outcome. METHODS: This was a longitudinal study of a prospectively developed database. All patients with a diagnosis of TLE were studied at the outpatient epilepsy clinic, Shiraz, Iran, from 2008 until 2021. The Two-Step cluster analysis (Schwarz's Bayesian Criterion: BIC) was applied to the whole dataset considering the demographic data, clinical characteristics, imaging, and electroencephalography data. The seizure outcome was compared between the clusters of patients. RESULTS: Three hundred and seventy-four patients had the inclusion criteria and were studied. The Two-Step cluster analysis showed that there were two distinct clusters of patients with TLE. The most important clinical predictors were the presence (or absence) of focal impaired awareness seizures or focal to bilateral tonic-clonic seizures, aura with seizures, and the brain imaging findings. The seizure outcomes were significantly different between these two clusters (pâ¯=â¯0.008). CONCLUSION: The Two-Step cluster analysis could identify two distinct clusters of patients with TLE; these data are helpful in providing prognosis and counseling for patients and their care-givers. These data may also be used to develop a practical outcome prediction tool for patients with TLE.
