“…Regarding ischemic stroke, the most frequent in terms of etiology, two Finnish studies have opposite conclusions: Jakovljevic et al report the highest frequency on Monday and the lowest frequency on Saturday [12], while Haapaniemi et al describe the highest incidence during weekends and holidays [13].…”

Introduction. Circaseptan or weekly rhythm, despite not belonging to terrestrial rhythms and being a conventional one, influences the incidence of stroke through short-term lifestyle changes. Objectives. To investigate the presence of a weekly variation pattern in the onset of cerebrovascular pathology in patients admitted to Neurology Departments I and II of the County Hospital Cluj-Napoca over the course of 2012. Material and method. The study is based on demographic data, data referring to the day of onset, the type of stroke and the subtype of ischemic stroke, collected retrospectively from the observation sheets of 1083 patients with stroke admitted through the Emergency Room to Neurology Departments I and II of the County Hospital Cluj-Napoca. Diagnosis was defined according to updated World Health Organization criteria and the Trial of ORG 10172 in Acute Stroke Treatment Classification. Results and conclusions. The circaseptan variation of stroke onset reveals two incidence peaks, one over the weekend continuing through Monday, and one in the middle of the week. Age, sex and the type/subtype of stroke enhances one of these peaks.

“…Preventive factors are smoking, low socioeconomic status (SES), hypertension (HTN), dyslipidemia, hyperuricemia, cardiovascular disorders, carotid artery diseases, and obesity. [4][5][6][7] Some of the abovementioned risk factors have role on prognosis and also hospitalization period which are responsible for a part of cost and economic burden of stroke. 8 The major drugs abused in Iran are opium and its byproducts.…”

Background: Ischemic stroke as the major cause of mortality and morbidity worldwide has different risk factors. One of its modifiable risk factors is opium addiction whose role is not clear yet. This study aimed at assessing the hemodynamic parameters in ischemic stroke patients addicted to opium using transcranial Doppler (TCD) ultrasonography and comparing them with non-addicted patients. Methods: This comparative cross-sectional study was conducted in an academic hospital in the north of Iran in 2016. All the patients diagnosed as ischemic stroke underwent cerebrovascular ultrasound in the first 4 days of symptoms onset. Frequency of hemodynamic abnormalities confirmed by pulsatility index (PI) and mean flow velocity (MFV) were determined and compared between the two groups. The data were analyzed by chi-square test, t-test, and multiple logistic regression models using SPSS software. Results: A total of 353 patients with ischemic stroke (92 addicted and 261 non-addicted patients) were enrolled in the study. Univariate analysis indicated that the PI and MFV differences were statistically significant between two groups of addicted and nonaddicted patients (P = 0.0001). By multivariate logistic regression model, the age [odds ratio (OR) = 1.143], diabetes mellitus (DM) (OR = 3.875), hypertension (HTN) (OR = 2.557), and opium usage (OR = 9.615) had influence on PI and only opium usage (OR = 3.246) had influence on MFV. Conclusion: Opium usage affects the cerebral hemodynamic parameters and increases the chance of having abnormal PI as ten-fold and abnormal MFV as three-fold.

“…Stroke is considered as a prominent problem in public health and it is one of the major causes of mortality in many countries, all over the world, especially in Iran. There are huge annual costs for the diagnosis and treatment of these patients in addition to the high rate of mortality [1,2]. This shows the necessity of introduction and identification of the disease and providing effective methods for better treatments.…”

Among neurological patients, stroke is the most common cause of mortality. It is a health problem that is very costly all over the world. Therefore, the mortality due to the disease can be reduced by identifying and modifying the risk factors. Controllable factors which are contributing to stroke including hypertension, diabetes, heart disease, hyperlipidemia, smoking, and obesity. Therefore, by identifying and controlling the risk factors, stroke can be prevented and the effects of this disease could be reduced to a minimum. Therefore, for the quick and timely diagnosis of the disease, we need an intelligent system to predict the stroke risk. In this paper, a method has been proposed for predicting the risk rate of stroke which is based on fuzzy cognitive maps and nonlinear Hebbian learning algorithm. The accuracy of the proposed NHL-FCM model is tested using 15-fold cross-validation, for 90 actual cases, and compared with those of support vector machine and k-nearest neighbours. The proposed method shows superior performance with a total accuracy of (95.4 ± 7.5)%.
