Common Triggers of Transient Global Amnesia (TGA)
While the likelihood of experiencing a TGA episode after certain activities is generally low, there are several triggers that have been commonly identified. These triggers include strenuous physical activity, sudden exposure to extreme temperatures (hot or cold), minor head injuries, sexual intercourse, medical procedures like endoscopy or angiography, and psychological or emotional distress. Additionally, TGA episodes have been known to occur as a result of excessive alcohol consumption or the use of prescription or illicit drugs.
Risk Factors for Transient Global Amnesia (TGA)
When it comes to the risk factors associated with transient global amnesia (TGA), it is important to note that high blood pressure and high cholesterol, although significant risk factors for stroke, do not increase the likelihood of experiencing TGA. Gender also does not seem to play a role in the risk of developing TGA. However, there are two confirmed risk factors that have been identified.
The first confirmed risk factor for TGA is age. Individuals over the age of 50 have a higher risk of experiencing transient global amnesia. This suggests that age plays a significant role in the development of this condition.
The second confirmed risk factor for TGA is a history of migraines. Individuals with a history of migraines have a significantly increased risk of experiencing transient global amnesia. This indicates that there may be a link between migraines and the occurrence of TGA.
