RESUMO
CLINICAL RELEVANCE: Understanding the causes of visual symptoms in epilepsy patients is important for early diagnosis and taking precautions. BACKGROUND: The aim of this study is to evaluate the anterior and posterior segment parameters in patients with generalized tonic-clonic epilepsy (GTCE). METHODS: This retrospective study included 50 eyes of 50 patients with GTCE and 55 eyes of 55 healthy controls. For all participants, detailed ophthalmic examinations were obtained from the files of patients. Anterior segment parameters were measured using corneal topography and non-contact specular microscopy, and posterior segment parameters were measured using swept-source optical coherence tomography. RESULTS: The mean age of the patients with GTCE was 43.3 ± 13.2 years, and in the healthy controls it was 47.6 ± 10.7 years (p = 0.405). In GTCE patients, 34 patients were treated with monotherapy (MT) and 16 patients with polytherapy (PT). Central macular thickness (CMT) was statistically significantly thin in GTCE patients (p = 0.001). The average and four quadrants (superior, inferior, nasal, temporal) retinal nerve fibre layer (RNFL) were thinner in GTCE patients than in the healthy controls, but there was no statistically significant difference (p > 0.05, all). The central corneal thickness was statistically significantly thin in GTCE patients (p = 0.04). Endothelial cell density (ECD), endothelial cell number (ECN), and average cell area (ACA) were statistically significantly lower in GTCE patients than in the healthy controls (p < 0.05, all). Although the CMT, average, and four-quadrants RNFL were thinner in the PT group compared to the MT group, no statistically significant difference was observed (p > 0.05, all). Total high-order aberrations (HOAs) were 0.6 ± 0.4 in the MT group and 0.4 ± 0.1 in the PT group (p = 0.01). ECD, ECN, and ACA measurements were observed to be lower in the PT group compared to the MT group, but no statistically significant difference was detected (p > 0.05, all). CONCLUSION: There could be statistically significant differences between GTCE patients and healthy controls in anterior and posterior segment parameters. This situation may be due to the epilepsy itself or to the antiepileptic drugs.
RESUMO
OBJECTIVE: The link between headache and epilepsy is more prominent in patients with idiopathic/genetic epilepsy (I/GE). We aimed to investigate the prevalence of headache and to cluster patients with regard to their headache and epilepsy features. METHODS: Patients aged 6-40 years, with a definite diagnosis of I/GE, were consecutively enrolled. The patients were interviewed using standardized epilepsy and headache questionnaires, and their headache characteristics were investigated by experts in headache. Demographic and clinical variables were analyzed, and patients were clustered according to their epilepsy and headache characteristics using an unsupervised K-means algorithm. RESULTS: Among 809 patients, 508 (62.8%) reported having any type of headache; 87.4% had interictal headache, and 41.2% had migraine. Cluster analysis revealed two distinct groups for both adults and children/adolescents. In adults, subjects having a family history of headache, ≥5 headache attacks, duration of headache ≥ 24 months, headaches lasting ≥1 h, and visual analog scale scores > 5 were grouped in one cluster, and subjects with juvenile myoclonic epilepsy (JME), myoclonic seizures, and generalized tonic-clonic seizures (GTCS) were clustered in this group (Cluster 1). Self-limited epilepsy with centrotemporal spikes and epilepsy with GTCS alone were clustered in Cluster 2 with the opposite characteristics. For children/adolescents, the same features as in adult Cluster 1 were clustered in a separate group, except for the presence of JME syndrome and GTCS alone as a seizure type. Focal seizures were clustered in another group with the opposite characteristics. In the entire group, the model revealed an additional cluster, including patients with the syndrome of GTCS alone (50.51%), with ≥5 attacks, headache lasting >4 h, and throbbing headache; 65.66% of patients had a family history of headache in this third cluster (n = 99). SIGNIFICANCE: Patients with I/GE can be clustered into distinct groups according to headache features along with seizures. Our findings may help in management and planning for future studies.

BACKGROUND: The population-based information on the prevalence of stroke from rural areas of Middle East countries including Turkey is unknown. Our aim is to evaluate the prevalence of stroke in those ⩾18 years in the Turkish population in a rural area of Istanbul. METHODS: A cross-sectional door-to-door study was conducted in a rural area of Istanbul between 1 March and 30 March 2013. A research protocol recommended by World Health Organization for developing countries was used. Each screening teams consisted of one neurologist, one local nurse, and five surveyors. Teams were trained about the survey and questionnaire. The patients, who claimed to have suffered a stroke, were examined, and the diagnosis was confirmed by a neurologist on site. The findings and medical records were documented. RESULTS: In total, 2906 people ⩾18 years were screened. 50 stroke cases were detected. 80% of those were found to have had an ischemic stroke, 14% of those were hemorrhagic cases, and 6% of those had an unclassified stroke type. The overall prevalence rate in those ⩾ 18 years was 1.7%. The male/female ratio was 0.92. Young (<45) stroke prevalence was found to be 0.6%. CONCLUSION: This study was the first of its kind to show the stroke prevalence among Turkish population ⩾ 18 years in a rural area of Istanbul. When compared to other studies which investigate people ⩾45 years from Turkey, the result (in the same age group) was moderate high. The male/female ratio was low compared to many other studies.
RESUMO
INTRODUCTION: The aims of this study were to determine the severity of cognitive impairment with Brief Repeatable Battery Neuropsychology (BRB-N) and to show the benefits of cognitive rehabilitation programs to develop coping strategies for the retardation of cognitive losses in relapsing remitting multiple sclerosis (RRMS) patients. METHODS: The cognitive screening with BRB-N was performed in RRMS patients who had applied to the MS outpatient clinic of Bakirköy Psychiatric and Neurological Diseases Hospital, had an Expanded Disability Status Scale (EDSS) score between 1.0 and 5.5, and had no other cognitive disease or used drugs that effected the cognitive status. Thirty two patients with cognitive impairment underwent consecutive computer-assisted cognitive rehabilitation program once a week for 8 weeks conducted by psychologists. The effects of the program were evaluated with the tests repeated every 4 weeks. RESULTS: The mean age of the patients was 36.09±7.19 years. Their initial and control test scores were found to be paced auditory serial addition test (PASAT) 29.21±17.97; 42.43±15.43, Selective Reminding Test-Total Learning (SRT-TL) 8.03±2.36; 10.09±1.77, Selective Reminding Test-Long-term Memory (SRT-DR) 6.72±2.74; 9±2.29, Spatial Recall Test-Total Learning (SPART-TL) 4.72±2.02; 4.22±1.74, Spatial Recall Test-Long-term Memory (SPART-DR) 5.94±2.54; 5.16±2.23, Symbol Digit Modalities Test (SDMT) 40.44±17.04; 46.47±17.94, Word Fluency Test (WLG) 32.88±9.87; 40.44±9.95 respectively. There was no significant statistical difference between Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ) and SPART values of preface, 1st control and 2nd control (p>0.05). There was significant statistical difference between PASAT, WLG, SDMT, SRT-TL, SRT-DR values of Preface, 1st control, and 2nd control (p=0.0001). CONCLUSION: It was determined that on distinctive improvement on sustaining attention, working memory and information processing speed, and verbal fluency and verbal learning with cognitive rehabilitation, no changes were observed on visuospatial learning. This approach is hopeful and further comprehensive studies are needed.
