Risk factors
By Mayo Clinic staffInterestingly, high blood pressure and high cholesterol — which are closely linked to strokes — are not risk factors for transient global amnesia. Your sex doesn't seem to affect your risk, either.
The clearest risk factors are:
- Age. People age 50 and older have a higher risk of transient global amnesia than do younger people.
- History of migraines. If you have migraines, your risk of transient global amnesia is significantly higher than that of someone without migraines.
