Abstract
We conducted a nation-wide survey using a questionnaire to clarify the current status of clinical practice of transient ischemic attack (TIA) in stroke specialized facilities in our country. We sent a questionnaire to directors of 683 stroke teaching hospitals certified by Japan Stroke Society. The response rate was 72.3%. According to this questionnaire survey, clinical practice of TIA in stroke specialized hospitals seemed to be generally reasonable. In addition, the present results demonstrated that new definition of TIA as duration of symptom <1 hour and the predictive scores of stroke risk after TIA such as ABCD2 score were hardly widespread, and that the rate of accurate diagnosis of TIA by general physicians was supposed to be considerably low.
