Abstract

Stroke is the third major reason of death in developed countries and the most prevalent disabling neurologic disorder. One of the approaches to recognize the brain damage is MRI. Presence of an acute damage in MRI of brain with DWI (diffusion weighted imaging) in patients suffering from TIA (transient ischemic attack). Therefore, cognition of the risk factors which can clinically interfere the DWI, might be helpful for making the best decision about the patients suffering from TIA. The purpose of this study is evaluation of the amount of positivity of DWI in the patients suffering from TIA and the correlation of these patients with ABCD scoring. Contributors were patients suffering from TIA hospitalized in neurology department of Sina hospital, who have been randomly selected among patients who had no problem with being studied. These patients were surveyed for one week. After the results of DWI were submitted, the study cases were divided into two groups, one the persons with positive DWI and the other one with typical DWI, and ABCD2 scorings and effecting parameters in ABCD2 scores in these two groups were compared. Raw data were entered in the SPSS software ver.17, and then the non-parametric statistic Chisquared test was used to analysis the data and the meaningful levels were surveyed (P-Value> 0.05). In this study, 240 male took part, 73.8% of these persons had AC-TIA and 26.2% had PCTIA. Among 177 persons with AC-TIA, 79.7% of them were normal DWI and 20.3% equal to 36 persons were positive DWI. Then continuing the study, the same score of positive DWI person (36 persons) were selected from normal DWI persons randomly. The average of the age in the normal DWI group was 65.5±10.13, and in the positive DWI group was 68.2±8.3 years old. According to the results obtained from variable statistical tests, totally the ABCD2 scores have no meaningful relationship to the results obtained from DWI (p-Value<0.05), whilst the results depict a meaningful statistical correlation between results from DWI and two other parameters of ABCD2 which are Clinical Features and Symptom Duration (p-Value>0.05). However, discoveries of this study demonstrated no meaningful relationship between results of DWI (normal/positive) and other parameters of ABCD2 scoring such as age, blood pressure, and diabetes in the patients suffering from TIA (p-Value <0.05). The results of this study demonstrates that the total score of ABCD2 have no correlation with DWI results, but some of the parts defining the ABCD2 scores, have meaningful correlation with the results obtained from DWI.
