Stable TIA incidence amid aging supports sustained prevention; leaves open sex-specific factors in later female onset.
BACKGROUND: We describe the epidemiological trends of transient ischemic attack (TIA) in a 20-year population-based pilot study. METHODS: Trends in the incidence, risk factors and pre-TIA use of preventive treatments for TIA were observed from 1985 to 2004 according to the classic definition in the population of the city of Dijon, France (150,000 inhabitants). RESULTS: The raw and standardized incidence of TIA were stable over time. We observed a significant increase in the mean age at TIA onset in women only. The prevalence of hypercholesterolemia and diastolic blood pressure > or =90 mm Hg among patients with TIA increased significantly. This contrasts with falls in smoking and in history of previous myocardial infarction. CONCLUSION: The stability of classic TIA incidence, despite the rise in the proportion of elderly people, and the increase in the mean age at onset in women may be considered as a medical progress.

Béjot et al. (2006) conducted an observational in Transient Ischemic Attack (TIA). Time period (1985-2004) was evaluated on Incidence of TIA. The raw and standardized incidence of TIA remained stable from 1985 to 2004 in Dijon, France, while the mean age at TIA onset significantly increased in women.
