The exact number of people who have had a transient ischemic attack (TIA) is not known for certain, because people do not always recognize a TIA nor do they always seek medical help when they experience symptoms.
The following table estimates the prevalence of TIA by gender and age.1
| Age | Percentage who have had a TIA | |
|---|---|---|
| Men | 65–69 | 2.7% |
| 75–79 | 3.6% | |
| Women | 65–69 | 1.6% |
| 75–79 | 4.1% |
