Is transient global amnesia a mental illness?
Transient global amnesia is a sudden, temporary episode of memory loss that can’t be attributed to a more common neurological condition, such as epilepsy or stroke. During an episode of transient global amnesia, your recall of recent events simply vanishes, so you can’t remember where you are or how you got there.
Is transient global amnesia serious?
There is no treatment for transient global amnesia (TGA). The condition resolves on its own within 24 hours. However, treatment for a suspected cause may be recommended.
How long can transient global amnesia last?
Treatment. Transient global amnesia goes away on its own within 24 hours.
How common is transient epileptic amnesia?
In some people, they are very infrequent (less than one per year) whereas others experience them as often as once a week. The episodes are usually very similar to each other. Cognitive functions other than memory are judged to be intact during typical episodes by a reliable witness.
How long can TGA last?
TGA typically lasts for several hours, but can last up to ten hours. Since no memories are made during a TGA episode, the person will never remember what happened during this period, but all other memory is usually intact. Most people have only one episode of TGA during their lifetime.
What part of the brain is affected by TGA?
Transient global amnesia (TGA) is an episodic memory disorder that affects the hippocampus (Eustache et al., 1999). It typically occurs in middle-aged to elderly populations (Arena and Rabinstein, 2015). A large proportion of TGA cases are preceded by stressful events which may be emotional or physical (Fisher, 1982).
Is TGA a mini stroke?
It is often wrongly diagnosed as a transient ischemic attack (TIA) or ‘mini’ stroke. However, transient global amnesia does not have the sinister implications of a transient ischemic attack, it is not the precursor to a stroke.
What part of brain is affected in transient global amnesia?
Transient global amnesia (TGA) is an episodic memory disorder that affects the hippocampus (Eustache et al., 1999).
Can TGA be caused by Covid vaccine?
Of all TGA cases, 289 were associated with a COVID-19 vaccine, which represented the most frequent association. Women were mostly involved, with 87 (64.7%) reports.
Can transient global amnesia be caused by stress?
The main clinical feature of transient global amnesia (TGA) is an acute anterograde memory disturbance that resolves within 24 h. It often occurs in the context of physical or emotional stress.
Is transient epileptic amnesia hereditary?
The Oxford TGA study found a 1.75% of familial cases and no-one in control series. We are building such control series. TGA could be a hereditary disease with late age of symptoms and low penetrance.
Does Covid cause TGA?
An increased incidence of TGA has been suggested since the beginning of the COVID-19 pandemic, but still has to be confirmed, pertaining to COVID-19 infection itself or the stress induced by the constraints endured by the population. (Werner et al., 2020; Ramanathan and Wachsman, 2021; Hornick et al., 2022).

No treatment is needed for transient global amnesia. It resolves on its own and has no known lasting effects.
Can anxiety cause TGA?
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.
How rare is transient global amnesia?
Transient global amnesia (TGA) is a rare clinical syndrome with an incidence of 5.2-10/100,000 per year in the general population and 23.5-32/100,000 in individuals greater than 50 years old [1].
How often does TGA occur?

Are migraines genetic?
For example, if a child has hemiplegic migraine, a type that causes temporary weakness and paralysis, they may have a mutation in any of the following genes: Research into the causes of other types of migraine is ongoing. People with migraine often find that certain foods, situations, or environmental factors triggers migraine episodes.
