How is transient global amnesia treated?
No treatment is needed for transient global amnesia. It resolves on its own and has no known lasting effects.
How often can Transient global amnesia occur?
It’s not a risk factor for stroke or epilepsy. It’s possible to have a second episode of transient global amnesia, but it’s extremely rare to have more than two.
What drugs can cause transient global amnesia?
Iatrogenic amnesia is one of the main aetiologies of transient amnesia. Benzodiazepines and anticholinergic drugs are considered to be the drugs most often responsible for iatrogenic amnesia.
Is transient global amnesia a sign of dementia?
Transient global amnesia (TGA) is characterized by the sudden onset of anterograde amnesia, generally lasting up to 24 hours. It has an annual incidence of 3.4 to 10.4 per 100,000 people.

What triggers TGA?
Possible triggers of TGA include: Sudden immersion in cold or hot water. Strenuous physical activity. Sexual intercourse.
How long does transient global amnesia last?
Memory loss usually lasts 1 to 8 hours but may last 30 minutes up to 24 hours (rarely). Most people with transient global amnesia have only one episode in a lifetime, unless the cause is seizures or migraines.
Can transient global amnesia recur?
Background: Transient global amnesia (TGA) is a syndrome characterized by sudden anterograde amnesia off less than 24hs of duration, without other neurological symptoms. The annual recurrence risk is approximately 6-10[percnt].
What are the symptoms of transient global amnesia?
The main identifiable symptom of transient global amnesia is the sudden, but temporary, loss of short-term memory and not being able to form new memories. Symptoms include: Anxiety and agitation. Repeatedly asking questions about what is happening.
Can stress cause transient global amnesia?
The findings suggest a role of emotional stress factors in the manifestation of TGA in a subgroup of patients. Stress may be one trigger involved in the emergence of transient lesions in the hippocampal CA1 region, which are thought to be the structural and functional correlate of TGA.
Is transient global amnesia a TIA?
While transient decrease in blood flow (a transient ischemic attack or “TIA“) to the hippocampus can mimic TGA, TGA usually lasts longer than a typical transient ischemic attack. 1 There is no clear relationship between stroke risk factors and TGA.
Is a TGA a stroke?
Although neurologists generally view TGA as a benign entity, its exact prognosis remains unclear. Although many studies have supported the benign nature of TGA,6,8–17 others have suggested that TGA may be a vascular prelude18 that confers the same risk of stroke as transient ischemic attack (TIA).
Do statins cause transient global amnesia?
This is a first report of what may be transient global amnesia linked to rosuvastatin, although is as likely to be a general problem linked to statin intake. There are reports of possible transient global amnesia linked to simvastatin or pravastatin.
