Stroke mimic is a major diagnostic challenge and may be difficult to distinguish from real strokes. The aim of this study was to evaluate the relative frequency of stroke mimics in patients with clinical signs of stroke.
In this cross sectional-study, the medical records of 1985 patients with stroke admitted to Poursina Hospital were enrolled using the census technique. Data collection tool was a checklist which include age, sex, imaging results (MRI and CT scan and primary and final diagnoses.
Of the 1985 patients, 295 (14.9%) were identified with brain stroke mimics. The mean age in the group of patients with mimics and real stroke were 66.5±16.4 years and 72.4±9.6 years, respectively. The highest number of stroke belonged to 61-80 years in stroke groups (68.8%) and mimics (58.3%), respectively. There was a significant correlation between age and early diagnosis of stroke or stroke mimic (P<0.0001). The highest frequency of stroke mimics was related to brain tumors (10.5%), hypoglycemia (9.2%) and toxic poisoning (8.5%).
Due to the high number of stroke mimics, further attention is necessary to aid in differential diagnosis and clinical procedures in patients with stroke signs.
类卒中是一项重大的诊断挑战，可能难以与真正的卒中相区分。本研究的目的是评估具有卒中临床体征的患者中类卒中的相对发生率。
在这项横断面研究中，采用普查技术纳入了1985例入住普尔西纳医院的卒中患者的病历。数据收集工具是一份清单，包括年龄、性别、影像学结果（MRI和CT扫描）以及初步和最终诊断。
在1985例患者中，295例（14.9%）被确诊为类卒中。类卒中和真正卒中患者组的平均年龄分别为66.5±16.4岁和72.4±9.6岁。卒中组和类卒中组中，61 - 80岁年龄段的卒中患者数量最多，分别为68.8%和58.3%。年龄与卒中或类卒中的早期诊断之间存在显著相关性（P<0.0001）。类卒中的最高发生率与脑肿瘤（10.5%）、低血糖（9.2%）和中毒（8.5%）有关。
由于类卒中数量众多，在对有卒中体征的患者进行鉴别诊断和临床诊疗过程中，需要进一步予以关注。
