The mean age in the group of patients with mimics and real stroke were 66.5&plusmn;16.4 years and 72.4&plusmn;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%)<span dir="RTL">.</span></span></span></p> <p><span style="font-size:14px;"><span style="font-family:times new roman;"><span style="color:#0000FF;"><strong><em>Conclusion: </em></strong></span>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<span dir="RTL">.</span></span></span></p> frequency, brain stroke, stroke mimics 213 216 http://caspjim.com/browse.php?a_code=A-10-286-2&slc_lang=en&sid=1 Mozzafar Hosseininezhad hosseininezhadm@gmail.com 10031947532846009155 10031947532846009155 No Guilan university Reza Sohrabnejad 10031947532846009156 10031947532846009156 Yes Mobility Impairment Research, Health Research Institute, Babol, University of Medical Sciences, Babol, Iran
