Abstract
Background & Objectives: Stroke incidence is a multifactorial phenomenon and investigation of the relationship between seasonal-regional variation and stroke is the focus of current studies. Based on seasonal, diurnal and hourly variations, incidence of different stroke was compared in this study. Material & Methods: In this retrospective study, 1817 medical records of stroke patients admitted in 2010 were reviewed from Ahvaz medi-educational hospitals. The type of aphasia was diagnosed according to the patients’ speech and language characteristics. SPSS-16 was used to analyze the data. Results: 39.9% of the patients had stroke-induced aphasia, and the highest rate of stroke incidence was found to be in the Summer time (38.2%) on Saturdays (16.1%), and between 8-12 A.M. (P<0.05). Conclusion: It seems that incidence of all kinds of stroke is influenced by time variation, and future works are needed to strengthen the results of our study.
