Overview

The estimated incidence of TIA may range from 200,000 to 500,000 per year. The estimated prevalence of TIA approximates to about 5 million people which correlates to population prevalence of 2.3%. ^[1]^[2]^[3]

Epidemiology

There may be certain limitations to assess the accurate incidence and prevalence data on transient ischemic stroke due to different criterias used for TIA in different epidemiological studies. Also, there may be underestimation of transient focal neurological symptoms by public and health care system. However, the estimated incidence and the prevalence of TIA in USA in year the 1999 is as follows:^[1]^[2]^[3]

Demographics

Age

The incidence of TIA increases remarkably with age irrespective of gender and race.^[1]

Gender

The incidence of TIA is more common in males.^[1]

Race

The incidence of TIA is high among African American race in older age group. However, the incidence of TIA is reported to be high in Mexican Americans compared with non-Hispanic whites at younger ages.^[1]
